The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

[0053] The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology.

The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

[0055] According to an embodiments, the antenna module 197 may form an mmWave antenna module. According to an embodiment, the mmWave antenna module may include a printed circuit board, a RFIC disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high-frequency band (e.g., the mmWave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the designated high-frequency band.

[0056] At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

[0057] According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 or 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service.

[0060] According to an embodiment, the electronic device 101 may be configured to provide a user with augmented reality (AR), virtual reality (VR), or mixed reality (MR) combining the augmented reality and the virtual reality. For example, the electronic device 101 may be configured to provide virtual reality (or virtual space) to the user, based on receiving data about an image from outside of the electronic device 101. Virtual reality may be represented based on two dimensions and/or three dimensions. For example, an image provided by the electronic device 101 may include a still image and/or video for realizing virtual reality. For example, the electronic device 101 may be configured to provide augmented reality to the user, by superimposing a virtual object on a real image representing an external environment of the electronic device 101. The real image may correspond to the external environment. The virtual object may include at least one of text and image corresponding to various information related to an object included in the real image. However, the virtual object is not limited thereto, and the virtual object may include at least one of text and image corresponding to various information related to another object distinguished from the object included in the real image. For example, the electronic device 101 may be referred to as at least one of a virtual reality (VR) device and a mixed reality (MR) device. For example, since the electronic device 101 may be used when being worn on the user's head, it may be referred to as a head mounted display device (HMD device).

[0061] According to an embodiment, the first housing 210 may form (or define) a part of an outer surface of the electronic device 101. The first housing 210 may form (or define) a part of a space in which various components of the electronic device 101 may be disposed. The first housing 210 may support various components of the electronic device 101. For example, the plurality of lens supports 230, the cover 240, and/or the first pad 250 may be coupled to the first housing 210. The first housing 210 may surround (or cover) the part B1 of the user's body when the electronic device 101 is worn by the user. For example, the first housing 210 may at least partially accommodate the part B1 of the user's body when the electronic device 101 is worn by the user. For example, the first housing 210 may be in contact with the part B1 of the user's body when the electronic device 101 is worn by the user, but the first housing 210 is not limited thereto. For example, the first housing 210 may be referred to as a main housing. For example, since the first housing 210 provides the overall framework of the electronic device 101, it may be referred to as a frame.

[0062] According to an embodiment, the second housing 220 may form (or define) another part of the outer surface of the electronic device 101. The second housing 220 may form (or define) another part of a space in which various components of the electronic device 101 may be disposed. The second housing 220 may support various components of the electronic device 101. For example, the second housing 220 may support the second pad 260. The second pad 260 may be disposed on the second housing 220. The second housing 220 may surround (or cover) the part B1 of the user's body when the electronic device 101 is worn by the user. For example, the second housing 220 may at least partially accommodate the part B1 of the user's body when the electronic device 101 is worn by the user. For example, the second housing 220 may be in contact with the part B1 of the user's body when the electronic device 101 is worn by the user, but the second housing 220 is not limited thereto. The second housing 220 may be movable with respect to the first housing 210. For example, the second housing 220 may be movable with respect to the first housing 210 so that the part B1 of the user's body is accommodated in a space s1 between the first housing 210 and the second housing 220. For example, the second housing 220 may be movable with respect to the first housing 210 so that it is close to the first housing 210 or away from the first housing 210. As the second housing 220 is movable with respect to the first housing 210, a size of the space s1 between the first housing 210 and the second housing 220 may be adjusted (or changed) to correspond to a size of the part B1 of the user's body. The second housing 220 may be referred to as a sub-housing. The second housing 220 may be referred to as a band housing.

[0063] According to an embodiment, each of the plurality of lens supports 230 may correspond to the user's eyes of the electronic device 101. Each of the plurality of lens supports 230 may face the user's eyes when the electronic device 101 is worn by the user. Each of the plurality of lens supports 230 may be coupled to the first housing 210. For example, a part of each of the plurality of lens supports 230 may be disposed (or accommodated) inside the first housing 210. For example, another part of each of the plurality of lens supports 230 may protrude outside the first housing 210. The plurality of lens supports 230 may include a first lens support 231 and a second lens support 232.

[0064] According to an embodiment, the first lens support 231 may be movable with respect to the first housing 210 to face the user's eyes. For example, the first lens support 231 may be movable with respect to the first housing 210 to be close to or away from the second lens support 232. The first lens support 231 may be coupled to a first lens 231a. The first lens 231a may refract (or distort) light emitted from at least one display of the electronic device 101 so that the electronic device 101 may provide virtual reality. The first lens 231a may be exposed to the outside of the first housing 210. The first lens 231a may be disposed outside the first housing 210.

[0065] According to an embodiment, the second lens support 232 may be movable with respect to the first housing 210 to face the user's eyes. For example, the second lens support 232 may be movable with respect to the first housing 210 to be close or away from the first lens support 231. As the first lens support 231 and the second lens support 232 are movable with respect to each other, a distance between the first lens 231a and a second lens 232a may be adjusted to correspond to an ‘inter pupillary distance’ (in short, gIPD) of the user. The second lens support 232 may be coupled to the second lens 232a. The second lens 232a may refract (or distort) light emitted from at least one display of the electronic device 101 so that the electronic device 101 may provide virtual reality. The second lens 232a may be exposed to the outside of the first housing 210. The second lens 232a may be disposed outside the first housing 210.

[0066] According to an embodiment, the cover 240 may reduce (or suppress) dispersing light passing through the first lens 231a and the second lens 232a to the outside of the cover 240, in a state that the electronic device 101 is worn by the user. As the cover 240 reduces a transfer of light passing through the first lens 231a and the second lens 232a to the outside of the cover 240, the electronic device 101 may provide, to the user, an environment of immersed virtual reality. The cover 240 may cover (or surround) the part B1 of the user's body when the electronic device 101 is worn by the user. For example, the cover 240 may be in contact with the part B1 of the user's body when the electronic device 101 is worn by the user. The cover 240 may be disposed on the first housing 210. For example, the cover 240 may be disposed on a surface of the first housing 210 facing the part B1 of the user's body when the electronic device 101 is worn by the user. The cover 240 may be penetrated by the first lens support 231 and the second lens support 232. For example, the cover 240 may include a plurality of holes 241 accommodating each of the first lens support 231 and the second lens support 232. For example, since the cover 240 covers the user's face when the electronic device 101 is worn by the user, it may be referred to as a face cover.

[0067] According to an embodiment, the first pad 250 may support the electronic device 101 when the electronic device 101 is worn by the user. The first pad 250 may maintain a position of the electronic device 101 with respect to the part B1 of the user's body when the electronic device 101 is worn by the user. The first pad 250 may be in contact with the user's forehead when the electronic device 101 is worn by the user. The first pad 250 may be coupled to the first housing 210. The first pad 250 may be disposed on the first housing 210. According to an embodiment, the first pad 250 may be movable with respect to the first housing 210. For example, the first pad 250 can be rotated (or be tilted) with respect to the first housing 210. As the first pad 250 is movable with respect to the first housing 210, a posture (or angle) of the first pad 250 with respect to the first housing 210 may be adjusted (or changed). As the posture of the first pad 250 with respect to the first housing 210 is changed, the first pad 250 may be stably in contact with the user's forehead. For example, since the first pad 250 supports the user's forehead when the electronic device 101 is worn by the user, it may be referred to as a front pad (or front cushion).

[0068] According to an embodiment, the second pad 260 may support the electronic device 101 when the electronic device 101 is worn by the user. The second pad 260 may maintain the position of the electronic device 101 with respect to the part B1 of the user's body when the electronic device 101 is worn by the user. For example, the second pad 260 may be in contact with the user's back of head when the electronic device 101 is worn by the user. The second pad 260 may be coupled to the second housing 220. The second pad 260 may be disposed on the second housing 220. The second pad 260 may be disposed on a surface of the second housing 220 facing the part B1 of the user's body when the electronic device 101 is worn on the user.

[0080] According to an embodiment, the first support part 211a may face the printed circuit board 281. The printed circuit board 281 may be disposed on (or within) the first support part 211a. The printed circuit board 281 may be disposed (or interposed) between the first support part 211a and the bracket 270. The first pad 250 may be disposed on the first support part 211a.

[0081] According to an embodiment, at least one first band part 211b may surround (or cover) a part of the user's body (e.g., the user's body part B1 of FIG. 2C), in a state that the electronic device 101 is worn by the user. The at least one first band part 211b may have a shape extending from the first support part 211a. For example, the first band part 211b may extend in a direction away from the first support part 211a. For example, the first band part 211b may include a plurality of first band parts spaced apart from each other, but the first band part 211b is not limited thereto.

[0082] According to an embodiment, the second case 212 may include a second support part 212a and/or at least one second band part 212b.

[0083] According to an embodiment, the second support part 212a may be coupled to the first support part 211a. For example, a shape of the second support part 212a may correspond to the shape of the first support part 211a. The first support part 211a and the second support part 212a may be coupled with each other to provide a space in which components of the electronic device 101 may be disposed. For example, a part of each of the bracket 270, the printed circuit board 281, and the plurality of lens supports 230 may be disposed between the first support part 211a and the second support part 212a. The second support part 212a may include a plurality of lens openings through which another part of each of the plurality of lens supports 230 passes. The other part of each of the plurality of lens supports 230 may be exposed to the outside of the first housing 210 by penetrating the plurality of lens openings. The second support part 212a may support the cover 240. For example, the cover 240 may be disposed on the second support part 212a.

[0084] According to an embodiment, at least one second band part 212b may be coupled to at least one first band part 211b. For example, a shape of at least one second band part 212b may correspond to the shape of at least one first band part 211b.

The part of the band 291a may be surrounded (or surrounded) by the first band part 211b and the second band part 212b.

[0085] According to an embodiment, the front panel 213 may cover at least one of components in the first housing 210 so that the components in the first housing 210 are not visible from the outside. The front panel 213 may be disposed on the first housing 210. For example, the front panel 213 may be disposed on the first support part 211a of the first housing 210.

[0086] According to an embodiment, the visor 214 may be disposed on the first housing 210. The visor 214 may be disposed on the front panel 213. For example, at least part of the visor 214 may be formed of a material that is substantially transparent or substantially translucent. Thus, a camera (e.g., the camera module 180 of FIG. 1) of the electronic device 101 may receive light from the outside of the electronic device 101, but the camera is not limited thereto.

[0087] According to an embodiment, the second housing 220 may include a third case 221 and/or a fourth case 222. The third case 221 and the fourth case 222 may be coupled to each other. The third case 221 and the fourth case 222 may be coupled to each other to form (or define) the second housing 220.

[0088] According to an embodiment, the third case 221 may face the second case 212. The third case 221 may support the second pad 260. The second pad 260 may be disposed on the third case 221. A part of the second adjustment module 292 may protrude (or be exposed) to the outside of the third case 221.

[0089] According to an embodiment, the fourth case 222 may be coupled to the third case 221. Another part of the band 291a may extend within the third case 221 and the fourth case 222. The knob 291b may protrude to the outside of the fourth case 222.

[0090] For example, in order to provide more realistic virtual reality to the user, a distance between the first lens support 231 and the second lens support 232 may be adjusted (or changed), based on the user's inter pupillary distance.

[0091] FIG. 4A is a top plan view of an example electronic device according to an embodiment when a distance between a first lens and a second lens is a first distance. FIG. 4B is a top plan view of an example electronic device according to an embodiment when a distance between a first lens and a second lens is a first distance.

[0092] Referring to FIGS. 4A and 4B, according to an embodiment, an electronic device 101 may include the first lens support 231, the second lens support 232, a supporting member 310, a pinion gear 320, a first adjusting structure 330, and a second adjusting structure 340.

[0093] According to an embodiment, the first lens support 231 may support a first lens 231a. The first lens support 231 may be coupled to the first lens 231a. The first lens 231a may move together with the first lens support 231 when the first lens support 231 moves, by being coupled to the first lens support 231. The first lens 231a may be exposed to the outside of the supporting member 310. The first lens 231a may be disposed outside the supporting member 310. The first lens support 231 may be movable with respect to the supporting member 310. For example, the first lens support 231 may be movable with respect to the supporting member 310 along a first direction (e.g., +x direction) away from the second lens support 232 or a second direction (e.g., −x direction) approaching the second lens support 232. According to an embodiment, the first lens support 231 may include a first rack gear 231b.

[0094] According to an embodiment, the first rack gear 231b may be coupled to the first lens support 231. For example, the first rack gear 231b may be integrally formed with the first lens support 231, but the first rack gear 231b is not limited thereto. For example, the first rack gear 231b may be formed separately from the first lens support 231, and then, coupled to the first lens support 231. The first rack gear 231b may be engaged with the pinion gear 320. For example, the first rack gear 231b may include a plurality of gear teeth engaged with the pinion gear 320. The plurality of gear teeth of the first rack gear 231b may be arranged to be spaced apart from each other along the first direction (e.g., +x direction) and/or the second direction (e.g., −x direction).

[0095] According to an embodiment, the second lens support 232 may support the second lens 232a. The second lens support 232 may be coupled to the second lens 232a. The second lens 232a may move together with the second lens support 232 when the second lens support 232 moves, by being coupled to the second lens support 232. The second lens 232a may be exposed to the outside of the supporting member 310. The second lens 232a may be disposed outside the supporting member 310. The second lens support 232 may be movable with respect to the supporting member 310. For example, the second lens support 232 may be movable relative to the supporting member 310 along the second direction (e.g., −x direction) away from the first lens support 231 or the first direction (e.g., +x direction) approaching the first lens support 231. According to an embodiment, the second lens support 232 may include a second rack gear 232b.

[0096] According to an embodiment, the second rack gear 232b may be coupled to the second lens support 232. For example, the second rack gear 232b may be integrally formed with the second lens support 232, but the second rack gear 232b is not limited thereto. For example, the second rack gear 232b may be formed separately from the second lens support 232, and then, coupled to the second lens support 232. The second rack gear 232b may be engaged with the pinion gear 320. For example, the second rack gear 232b may include a plurality of gear teeth engaged with the pinion gear 320. The plurality of gear teeth of the second rack gear 232b may be arranged to be spaced apart from each other along the first direction (e.g., +x direction) and/or the second direction (e.g., −x direction). According to an embodiment, the second rack gear 232b may face the first rack gear 231b. For example, the second rack gear 232b may face away from the first rack gear 231b. For example, the second rack gear 232b may be spaced apart from the first rack gear 231b in a direction perpendicular to the first direction (e.g., +x direction).

[0097] According to an embodiment, the supporting member 310 may accommodate a part of the first lens support 231, a part of the second lens support 232, the first adjusting structure 330, and/or the second adjusting structure 340. For example, a part of the first lens support 231, a part of the second lens support 232, the first adjusting structure 330, and/or the second adjusting structure 340 may be disposed inside the supporting member 310. For example, the supporting member 310 may be one of a first housing (e.g., the first housing 210 in FIGS. 2A, 2B, and 2C), and a bracket (e.g., the bracket 270 in FIG. 3), but the supporting member 310 is not limited thereto.

[0098] According to an embodiment, the pinion gear 320 may be engaged with the first rack gear 231b and the second rack gear 232b. For example, the pinion gear 320 may include a plurality of gear teeth engaged with the first rack gear 231b and the second rack gear 232b. The pinion gear 320 may be disposed on the supporting member 310. For example, the pinion gear 320 may be coupled to the supporting member 310. The pinion gear 320 may be rotatable with respect to the supporting member 310 by a movement of the first lens support 231 and the second lens support 232. For example, the pinion gear 320 may be rotatable with respect to the supporting member 310, in a first rotation direction r1 and/or a second rotation direction r2. When the pinion gear 320 rotates, a distance between the first lens 231a and the second lens 232a may be changed. For example, when the pinion gear 320 rotates, the distance between the first lens 231a and the second lens 232a may be changed. The pinion gear 320 is engaged with the first rack gear 231b and the second rack gear 232b to maintain the distance between the first lens 231a and the second lens 232a. For example, the pinion gear 320 may restrict a movement of the first lens support 231 and the second lens support 232, by engaging with the first rack gear 231b and the second rack gear 232b before an external force (e.g., a force applied by a user) is applied to the first lens support 231 and the second lens support 232. For example, when the first lens support 231 moves in the first direction (e.g., +x direction) away from the second lens support 232, the first rack gear 231b may move with respect to the second rack gear 232b along the first direction (e.g., +x direction). The distance between the first lens 231a and the second lens 232a may be changed from a first distance d1 to a second distance d2, by a movement of the first rack gear 231b with respect to the second rack gear 232b in the first direction (e.g., +x direction).

[0099] The first distance d1 may indicate a first position of the first lens support 231 with respect to the second lens support 232. For example, the first distance d1 may be represented as the first position of the first lens support 231 with respect to the second lens support 232. The second distance d2 may indicate a second position of the first lens support 231 with respect to the second lens support 232. For example, the second distance d2 may be represented as the second position of the first lens support 231 with respect to the second lens support 232. The second distance d2 may be different from the first distance d1. For example, the second distance d2 may be greater than the first distance d1, but the second distance d2 is not limited thereto. For example, the second distance d2 may be less than the first distance d1. When the distance between the first lens 231a and the second lens 232a is changed from the first distance d1 to the second distance d2, the pinion gear 320 may rotate along the first rotation direction r1. For example, as the pinion gear 320 rotates along the first rotation direction r1, the distance between the first lens 231a and the second lens 232a may increase. For example, as the pinion gear 320 rotates along the first rotation direction r1, the first lens support 231 may move along the first direction (e.g., +x direction), and the second lens support 232 may move along the second direction (e.g., −x direction) opposite to the first direction (e.g., +x direction).

[0100] For example, when the first lens support 231 moves in the second direction (e.g., −x direction) approaching the second lens support 232, the first rack gear 231b may move with respect to the second rack gear 232b along the second direction (e.g., −x direction). The distance between the first lens 231a and the second lens 232a may be changed from the second distance d2 to the first distance d1 by a movement of the first rack gear 231b with respect to the second rack gear 232b in the second direction (e.g., −x direction). When the distance between the first lens 231a and the second lens 232a is changed from the second distance d2 to the first distance d1, the pinion gear 320 may rotate along the second rotation direction r2 opposite to the first rotation direction r1. For example, as the pinion gear 320 rotates along the second rotation direction r2, the distance between the first lens 231a and the second lens 232a may be reduced. For example, as the pinion gear 320 rotates along the second rotation direction r2, the first lens support 231 may move along the second direction (e.g., −x direction), and the second lens support 232 may move in the first direction (e.g., +x direction).

[0101] According to an embodiment, the first adjusting structure 330 and the second adjusting structure 340 may be configured to guide a movement of the first lens support 231 with respect to the second lens support 232. For example, since an inter pupillary distance is different for each user, the distance between the first lens support 231 and the second lens support 232 needs to be precisely adjusted (or changed). Hereinafter, the first adjusting structure 330 and/or the second adjusting structure 340 capable of precisely adjusting the distance between the first lens 231a and the second lens 232a will be described.

[0102] Hereinafter, the first adjusting structure 330 and the second adjusting structure 340 will be described based on the first lens support 231, but embodiments of the disclosure are not limited thereto. For example, the first adjusting structure 330 and the second adjusting structure 340 may be configured to guide a movement of the second lens support 232 with respect to the first lens support 231.

[0103] FIG. 5A illustrates a first lens support and a first adjusting structure according to an embodiment. FIG. 5B illustrates a coupling relationship of an example first adjusting structure according to an embodiment.

[0104] Referring to FIGS. 5A and 5B, according to an embodiment, a first adjusting structure 330 may include a first flange part 331, a first protruding part 332, a first opening 333, a second flange part 334, a second protruding part 335, and a second opening 336.

[0105] Hereinafter, the first adjusting structure 330 will be described as being coupled to the first lens support 231, but the first adjusting structure 330 is not limited thereto. For example, the first adjusting structure 330 may be coupled to a supporting member (e.g., the supporting member 310 in FIGS. 4A and 4B). For example, the first adjusting structure 330 may be coupled to a second lens support (e.g., the second lens support 232 in FIG. 2B).

[0106] According to an embodiment, the first adjusting structure 330 may be coupled to the first lens support 231. For example, the first flange part 331, the first protruding part 332, and the first opening 333 of the first adjusting structure 330 may be integrally formed with the first lens support 231, but the first adjusting structure 330 is not limited thereto. For example, the first flange part 331, the first protruding part 332, and the first opening 333 may be formed separately from the first lens support 231, and then, coupled to the first lens support 231 through a fastening member f1 (e.g., screw, rivet, and/or pin). The second flange part 334, the second protruding part 335, and the second opening 336 may be formed separately from the first lens support 231, and then, coupled to the first lens support 231 through the fastening member f1, but the second flange part 334, the second protruding part 335, and the second opening 336 are not limited thereto. For example, the second flange part 334, the second protruding part 335, and the second opening 336 may be integrally formed with the first lens support 231.

[0107] According to an embodiment, the first flange part 331 may be connected to the first protruding part 332. The first flange part 331 may have a shape extending in a first direction (e.g., +x direction) or a second direction (e.g., −x direction). For example, the first flange part 331 may extend along the first direction (e.g., +x direction) or the second direction (e.g., −x direction) to have a length in the first direction (e.g., +x direction) or the second direction (e.g., −x direction). According to an embodiment, the first flange part 331 may be formed of a metal or polymer material. For example, the first flange part 331 may be formed of plastic.

[0108] According to an embodiment, the first protruding part 332 may protrude from the first flange part 331. For example, the first protruding part 332 may protrude to outside of the first flange part 331. For example, the first protruding part 332 may protrude (or extend) along a direction away from the first flange part 331. For example, the first protruding part 332 may protrude (or extend) in a direction away from the first opening 333.

[0109] According to an embodiment, the first opening 333 may penetrate the first flange part 331. The first opening 333 may be formed (or defined) in the first flange part 331. The first opening 333 may be surrounded (or covered) by the first flange part 331. As the first flange part 331 is penetrated by the first opening 333, the first flange part 331 may be deformable by an external force. For example, the first flange part 331 may be compressed by an external force. A shape of the first opening 333 may be deformed when a shape of the first flange part 331 is deformed.

[0110] According to an embodiment, the first opening 333 may include a first protruding area 333a. The first protruding area 333a may be formed to reduce damage caused by stress on the first flange part 331. For example, the first protruding area 333a may be formed to maintain a thickness of the first flange part 331 to be substantially constant. The thickness of the first flange part 331 may indicate a distance in a direction perpendicular to the extending direction when the first flange part 331 extends along the circumference of the first opening 333. The first protruding area 333a may correspond to the first protruding part 332. For example, a shape of the first protruding area 333a may correspond to the shape of the first protruding part 332. For example, a position of the first protruding area 333a may correspond to a position of the first protruding part 332. For example, the first protruding area 333a may be symmetrical to the first protruding part 332 based on the first direction (e.g., +x direction).

[0111] According to an embodiment, the second flange part 334 may be connected to the first protruding part 332. The second flange part 334 may have a shape extending along the first direction (e.g., +x direction) or a second direction (e.g., −x direction). For example, the second flange part 334 may have a length in the first direction (e.g., +x direction) or the second direction (e.g., −x direction) by extending along the first direction (e.g., +x direction) or the second direction (e.g., −x direction). According to an embodiment, the second flange part 334 may be disposed (or stacked) on the first flange part 331. The second flange part 334 may overlap with at least a part of the first flange part 331. The second flange part 334 may be aligned with the first flange part 331. For example, the second flange part 334 may be fully overlaid on the first flange part 331, but the second flange part 334 is not limited thereto. For example, the second flange part 334 may be misaligned with the first flange part 331. When the second flange part 334 and the first flange part 331 are misaligned with each other, a part of the second flange part 334 may not overlap with the first flange part 331. According to an embodiment, the second flange part 334 may be formed of a metal or polymer material. For example, the second flange part 334 may be formed of plastic.

[0112] According to an embodiment, the second flange part 334 may include at least one guide protrusion 334a. The guide protrusion 334a may protrude from the second flange part 334. For example, the guide protrusion 334a may extend along a direction (e.g., −y direction) toward the first flange part 331.

[0113] According to an embodiment, the second protruding part 335 may protrude from the second flange part 334. For example, the second protruding part 335 may protrude to the outside of the second flange part 334. For example, the second protruding part 335 may protrude (or extend) along a direction away from the second flange part 334. According to an embodiment, the second protruding part 335 may be disposed (or stacked) on the first protruding part 332. The second protruding part 335 may overlap with at least a part of the first protruding part 332. The second protruding part 335 may be aligned with the first protruding part 332. For example, the second protruding part 335 may be fully overlaid on the first protruding part 332, but the second protruding part 335 is not limited to thereto. For example, the second protruding part 335 may be misaligned with the first protruding part 332. When the second protruding part 335 and the first protruding part 332 are misaligned with each other, a part of the second protruding part 335 may not overlap with the first protruding part 332.

[0114] According to an embodiment, the second opening 336 may penetrate the second flange part 334. The second opening 336 may be formed (or defined) on the second flange part 334. The second opening 336 may be surrounded (or covered) by the second flange part 334. As the second flange part 334 is penetrated by the second opening 336, the second flange part 334 may be deformable by an external force. For example, the second flange part 334 may be compressed by an external force. A shape of the second opening 336 may be deformed when a shape of the second flange part 334 is deformed. According to an embodiment, the second opening 336 may be disposed (or stacked) on the first opening 333. The second opening 336 may overlap with at least a part of the first opening 333. The second opening 336 may be aligned with the first opening 333. The second opening 336 may be fully overlaid on the first opening 333, but the second opening 336 is not limited thereto. The second opening 336 may be misaligned with the first opening 333. When the second opening 336 and the first opening 333 are misaligned with each other, a part of the second opening 336 may not overlap with the first opening 333.

[0115] According to an embodiment, the second opening 336 may include a second protruding area 336a. The second protruding area 336a may be formed to reduce damage (e.g., caused by stress) on the second flange part 334. For example, the second protruding area 336a may be formed to maintain a thickness of the second flange part 334 to be substantially constant. The thickness of the second flange part 334 may indicate a distance in a direction perpendicular to the extending direction when the second flange part 334 extends along the circumference of the second opening 336. The second protruding area 336a may correspond to the second protruding part 335. For example, a shape of the second protruding area 336a may correspond to a shape of the second protruding part 335. For example, a position of the second protruding area 336a may correspond to a position of the second protruding part 335. For example, the second protruding area 336a may be symmetrical to the second protruding part 335 based on the first direction (e.g., +x direction).

[0116] According to an embodiment, the first lens support 231 may further include at least one guide hole 231c. The at least one guide hole 231c may penetrate the first lens support 231. The at least one guide hole 231c may correspond to at least one guide protrusion 334a. The at least one guide hole 231c may accommodate at least one guide protrusion 334a. The at least one guide protrusion 334a may be inserted into at least one guide hole 231c. When the first adjusting structure 330 is formed, the second flange part 334 may be stacked on the first flange part 331. For example, since at least one guide protrusion 334a of the second flange part 334 is inserted into at least one guide hole 231c, the second flange part 334 and the first flange part 331 may be aligned. As the fastening member f1 penetrates the first flange part 331 and the second flange part 334 after the second flange part 334 is stacked on the first flange part 331, production of the first adjusting structure 330 may be completed.

[0121] According to an embodiment, the plurality of second grooves 341b may correspond to a second protruding part 335. The plurality of second grooves 341b may be arranged with respect to the second protruding part 335. For example, the plurality of second grooves 341b may face the second protruding part 335. The plurality of second grooves 341b may be disposed (or stacked) on the plurality of first grooves 341a. According to an embodiment, each of the plurality of second grooves 341b may be misaligned with each of the plurality of first grooves 341a. For example, when each of the plurality of second grooves 341b and each of the plurality of first grooves 341a are misaligned with each other, a part of each of the plurality of second grooves 341b may not overlap with a part of each of a plurality of first grooves 341a.

[0122] According to an embodiment, the plurality of protrusions 342 may be spaced apart from each other. For example, the plurality of protrusions 342 may be arranged to be spaced apart from each other. For example, the plurality of protrusions 342 may be arranged to be spaced apart from each other along the first direction (e.g., +x direction), and/or the second direction (e.g., −x direction).

[0123] According to an embodiment, the plurality of first protrusions 342a may correspond to the first protruding part 332. The plurality of first protrusions 342a may be arranged with respect to the first protruding part 332. For example, the plurality of first protrusions 342a may face the first protruding part 332. The plurality of first protrusions 342a may be disposed (or interposed) between the plurality of first grooves 341a. According to an embodiment, at least one of the plurality of second grooves 341b may be disposed (or stacked) on the plurality of first protrusions 342a. For example, the at least one groove of the plurality of second grooves 341b may overlap with the plurality of first protrusions 342a. For example, the plurality of first protrusions 342a may be referred to as ‘a plurality of first gear teeth.’

[0124] According to an embodiment, the plurality of second protrusions 342b may correspond to the second protruding part 335. The plurality of second protrusions 342b may be arranged with respect to the second protruding part 335. For example, the plurality of second protrusions 342b may face the second protruding part 335.

[0125] According to an embodiment, the first adjusting structure 330 and the second adjusting structure 340 may be coupled to the supporting member 310. The first adjusting structure 330 and the second adjusting structure 340 may be located inside the supporting member 310. The first adjusting structure 330 and the second adjusting structure 340 may be disposed on the supporting member 310.

[0126] FIG. 7A is a top plan view illustrating a relationship between a first adjusting structure and a second adjusting structure when a distance between a first lens and a second lens is a first distance, according to an embodiment. FIG. 7B is a rear view illustrating a relationship between a first adjusting structure and a second adjusting structure when a distance between a first lens and a second lens is a first distance, according to an embodiment. FIG. 7C is a top plan view illustrating a relationship between a first adjusting structure and a second adjusting structure when a distance between a first lens and a second lens is a second distance, according to an embodiment. FIG. 7D is a rear view illustrating a relationship between a first adjusting structure and a second adjusting structure when a distance between a first lens and a second lens is a second distance, according to an embodiment.

[0127] Referring to FIG. 7A, according to an embodiment, a second adjusting structure 340 may be fastened on the supporting member 310. A position of the second adjusting structure 340 may be maintained when the first adjusting structure 330 moves with respect to the second adjusting structure 340. For example, the second adjusting structure 340 may be fixed when the first adjusting structure 330 moves with respect to the supporting member 310. For example, the second adjusting structure 340 may be fastened to the supporting member 310 by at least one fastening member f2 penetrating the second adjusting structure 340 and supporting member 310.

[0128] According to an embodiment, when a distance between a first lens (e.g., the first lens 231a of FIG. 2B) and a second lens (e.g., the second lens 232a of FIG. 2B) is a first distance (e.g., the first distance d1 of FIG. 4A), the first protruding part 332 may be positioned (or accommodated) inside a groove 341a-1 of the plurality of grooves (e.g., the plurality of first grooves 341a). For example, when the distance between the first lens 231a and the second lens 232a is the first distance d1, the first protruding part 332 may be positioned between the plurality of first protrusions 342a. For example, when the distance between the first lens 231a and the second lens 232a is the first distance d1, the first protruding part 332 may be engaged with the plurality of first protrusions 342a. As the first protruding part 332 and a plurality of first protrusions 342a are engaged with each other, the distance between the first lens 231a and the second lens 232a may be maintained at the first distance d1.

[0129] Referring to FIG. 7B, according to an embodiment, when the distance between the first lens 231a and the second lens 232a is the first distance d1, the second protruding part 335 may be positioned outside the plurality of grooves 341 (341b). For example, when the distance between the first lens 231a and the second lens 232a is the first distance d1, as the second flange part 334 is deformed by a contact with the second adjusting structure 340, the second protruding part 335 may be positioned outside the plurality of second grooves 341b. When the distance between the first lens 231a and the second lens 232a is the first distance d1, the second flange part 334 may be deformed in a direction away from the second adjusting structure 340 (e.g., −z direction) by a contact between the second adjusting structure 340 and the second protruding part 335. For example, when the distance between the first lens 231a and the second lens 232a is the first distance d1, the second flange part 334 may be deformed in a direction away from the plurality of second protrusions 342b (e.g., −z direction) by a contact between a protrusion 342b-1 of the plurality of second protrusions 342b and the second protruding part 335. For example, when the distance between the first lens 231a and the second lens 232a is the first distance d1, the second flange part 334 may be compressed by a contact with the second adjusting structure 340. A shape of the second opening 336 may be changed by a deformation of the second flange part 334. For example, the second opening 336 may be compressed by the deformation of the second flange part 334. For example, when the distance between the first lens 231a and the second lens 232a is the first distance d1, the engagement between the second protruding part 335 and the plurality of second protrusions 342b may be released.

[0130] According to an embodiment, as the first lens support 231 moves with respect to the second lens support 232 in a first direction (e.g., +x direction), the distance between the first lens 231a and the second lens 232a may be changed from the first distance d1 to a second distance (e.g., the second distance d2 of FIG. 4B).

[0131] Referring to FIG. 7C, according to an embodiment, when the distance between the first lens 231a and the second lens 232a is the second distance d2, the first protruding part 332 may be positioned outside the plurality of grooves 341. For example, when the distance between the first lens 231a and the second lens 232a is the second distance d2, as the first flange part 331 is deformed by a contact with the protrusion 342a-1 among the plurality of protrusions 342, the first protruding part 332 may be positioned outside the plurality of grooves 341. For example, when the distance between the first lens 231a and the second lens 232a is changed from the first distance d1 to the second distance d2, the first protruding part 332 may move toward the outside of the plurality of first grooves 341a by sliding to the protrusion 342a-1 among the plurality of first protrusions 342a. The first flange part 331 may be deformed in a direction (e.g., −z direction) away from the plurality of protrusions 342 by a contact between the first protruding part 332 and the protrusion 342a-1 among the plurality of first protrusions 342a. For example, the first flange part 331 may be compressed by a contact between the first protruding part 332 and the protrusion 342a-1 among the plurality of protrusions 342. A shape of the first opening 333 may be changed by the deformation of the first flange part 331. For example, the first opening 333 may be compressed as the first flange part 331 is compressed. For example, when the distance between the first lens 231a and the second lens 232a is the second distance d2, the engagement between the first protruding part 332 and the plurality of first protrusions 342a may be released.

[0132] Referring to FIG. 7D, according to an embodiment, when the distance between the first lens 231a and the second lens 232a is the second distance d2, the second protruding part 335 may be positioned (or accommodated) inside yet another groove 341b-1 among the plurality of grooves 341. For example, when the distance between the first lens 231a and the second lens 232a is the second distance d2, the second protruding part 335 may be positioned (or accommodated) inside the yet another groove 341b-1 among the plurality of second grooves 341b. For example, when the distance between the first lens 231a and the second lens 232a is the second distance d2, the second protruding part 335 may be positioned between the plurality of second protrusions 342b. For example, the second protruding part 335 may be engage with the plurality of first protrusions 342a When the distance between the first lens 231a and the second lens 232a is the second distance d2. For example, when the distance between the first lens 231a and the second lens 232a is changed from the first distance d1 to the second distance d2, the second protruding part 335 may move toward the inside of the other groove 341b-1 among the plurality of second grooves 341b by sliding to the protrusion 342b-1 of the plurality of second protrusions 342b. When the distance between the first lens 231a and the second lens 232a is changed from the first distance d1 to the second distance d2, as a contact between the second protruding part 335 and the protrusion 342b-1 of the plurality of second protrusions 342b is released, a shape of the second flange part 334 may be restored. As the shape of the second flange part 334 is restored, a shape of the second opening 336 may be restored. As the second protruding part 335 and the plurality of first protrusions 342a are engaged with each other, the distance between the first lens 231a and the second lens 232a may be maintained at the second distance d2.

[0133] As described above, according to an embodiment, as the plurality of first protrusions 342a and the plurality of second protrusions 342b are misaligned with each other, the electronic device 101 may provide a structure in which a distance between the first lens 231a and the second lens 232a is precisely adjusted. When the plurality of first protrusions 342a and the plurality of second protrusions 342b are aligned, when the distance between the first lens 231a and the second lens 232a is the first distance d1 and the second distance d2, the first protruding part 332 and the second protruding part 335 may be positioned to be aligned with each other. When the first protruding part 332 and the second protruding part 335 are positioned to be aligned with each other. When the distance between the first lens 231a and the second lens 232a is the first distance d1 and the second distance d2, the distance between the first lens 231a and the second lens 232a may not be precisely adjusted. According to an embodiment, since the plurality of first protrusions 342a and the plurality of second protrusions 342b are misaligned with each other, the electronic device 101 may provide a structure in which the first protruding part 332 and the second protruding part 335 are misaligned with each other when the distances between the first lens 231a and the second lens 232a are the first distance d1 and the second distance d2, respectively. Since the first protruding part 332 and the second protruding part 335 are misaligned with each other when the distances between the first lens 231a and the second lens 232a are the first distance d1 and the second distance d2, respectively, the distance between the first lens 231a and the second lens 232a may be precisely adjusted.

[0136] The second adjusting structure 340 of FIG. 8B may be a structure in which the structure of the second adjusting structure 340 of FIGS. 4A and/or 4B is changed, so redundant descriptions will be omitted.

[0137] Referring to FIG. 8A, according to an embodiment, the first flange part 331 (shown in FIG. 7C) and the second flange part 334 may be misaligned with respect to each other. For example, at least a part of the first flange part 331 may not overlap with the second flange part 334. For example, when the first adjusting structure 330 is viewed from above, at least a part of the second flange part 334 may be spaced apart from the first flange part 331 along a first direction (e.g., +x direction).

[0138] According to an embodiment, the first protruding part 332 and the second protruding part 335 may be misaligned with each other. For example, at least a part of the first protruding part 332 may not overlap with the second protruding part 335. For example, when the first adjusting structure 330 is viewed from above, at least a part of the second protruding part 335 may be spaced apart from the first protruding part 332 along a first direction (e.g., +x direction).

[0139] According to an embodiment, the first opening 333 and the second opening 336 may be misaligned with respect to each other. For example, at least a part of the first opening 333 may not overlap with the second opening 336. For example, when the first adjusting structure 330 is viewed from above, at least a part of the second opening 336 may be spaced apart from the first opening 333 along the first direction (e.g., +x direction).

[0140] Referring to FIG. 8B, according to an embodiment, a thickness of a plurality of first grooves 341a may correspond to a sum of a thickness of the first protruding part 332 and a thickness of the second protruding part 335. A thickness of one component may indicate a distance in +y direction, and the corresponding expression may be used substantially the same hereinafter. For example, the thickness of the plurality of first grooves 341a may be greater than or equal to the sum of the thicknesses of the first protruding part 332 and the thickness of the second protruding part 335.

[0141] According to an embodiment, the thickness of the plurality of first protrusions 342a may correspond to the sum of the thickness of the first protruding part 332 and the thickness of the second protruding part 335. For example, the thickness of the plurality of first protrusions 342a may be greater than or equal to the sum of the thickness of the first protruding part 332 and the thickness of the second protruding part 335.

[0142] FIG. 9A is a rear view illustrating a relationship between a first adjusting structure and a second adjusting structure when a distance between a first lens and a second lens is a first distance, according to an embodiment. FIG. 9B is a rear view illustrating a relationship between a first adjusting structure and a second adjusting structure when a distance between a first lens and a second lens is a second distance, according to an embodiment.

[0143] FIGS. 9A and 9B illustrate a relationship between the first adjusting structure 330 in FIG. 8A and the second adjusting structure 340 in FIG. 8B, according to a distance between a first lens (e.g., the first lens 231a of FIG. 2B) and a second lens (e.g., the second lens 232a of FIG. 2B).

[0144] Referring to FIG. 9A, according to an embodiment, when the distance between the first lens 231a and the second lens 232a is a first distance (e.g., the first distance d1 of FIG. 4A), the first protruding part 332 may be positioned outside a plurality of first grooves 341a. When the distance between the first lens 231a and the second lens 232a is the first distance d1, as the first flange part 331 is deformed by a contact between the first protruding part 332 and the second adjusting structure 340, the first protruding part 332 may be positioned outside the plurality of first grooves 341a. For example, when the distance between the first lens 231a and the second lens 232a is the first distance d1, the first flange part 331 may be deformed in a direction (e.g., −z direction) away from the plurality of first protrusions 342a by a contact between the first protruding part 332 and the protrusion 342a-1 among the plurality of first protrusions 342a. When the distance between the first lens 231a and the second lens 232a is the first distance d1, the first protruding part 332 may be positioned outside the plurality of first grooves 341a by being deformed in the direction (e.g., −z direction) away from the plurality of first protrusions 342a. When the distance between the first lens 231a and the second lens 232a is the first distance d1, the engagement between the first protruding part 332 and the plurality of first protrusions 342a may be released.

[0145] According to an embodiment, when the distance between the first lens 231a and the second lens 232a is the first distance d1, the second protruding part 335 may be positioned (or accommodated) inside the groove 341a-1 among the plurality of first grooves 341a. When the distance between the first lens 231a and the second lens 232a is the first distance d1, the second protruding part 335 may be positioned between the plurality of first protrusions 342a. When the distance between the first lens 231a and the second lens 232a is the first distance d1, the second protruding part 335 may be engaged with (any one of) the plurality of first protrusions 342a. As the second protruding part 335 and (any one of) the plurality of first protrusions 342a are engaged with each other, the distance between the first lens 231a and the second lens 232a may be maintained at the first distance d1.

[0146] According to an embodiment, as the first lens support 231 moves with respect to the second lens support 232 in the first direction (e.g., +x direction), the distance between the first lens 231a and the second lens 232a may be changed from the first distance d1 to the second distance d2.

[0147] Referring to FIG. 9B, according to an embodiment, when the distance between the first lens 231a and the second lens 232a is the second distance d2, the first protruding part 332 may be positioned (or accommodated) inside another groove 341a-2 among the plurality of first grooves 341a. For example, when the distance between the first lens 231a and the second lens 232a is changed from the first distance d1 to the second distance d2, the first protruding part 332 may move toward the inside of the other groove 341a-2 among the plurality of first grooves 341a by sliding to the protrusion 342a-1 of the plurality of first protrusions 342a. For example, when the distance between the first lens 231a and the second lens 232a is the second distance d2, the first protruding part 332 may be engaged with the plurality of first protrusions 342a.

[0148] According to an embodiment, when the distance between the first lens 231a and the second lens 232a is the second distance d2, the second protruding part 335 may be positioned outside the plurality of first grooves 341a. For example, when the distance between the first lens 231a and the second lens 232a is the second distance d2, as the second flange part 334 is deformed by a contact with the second adjusting structure 340, the second protruding part 335 may be positioned outside the plurality of first grooves 341a. For example, when the distance between the first lens 231a and the second lens 232a is the second distance d2, the second flange part 334 may be deformed in a direction (e.g., −z direction) away from the plurality of first protrusions 342a by a contact between the second protruding part 335 and the protrusion 342a-1 among the plurality of first protrusions 342a. For example, when the distance between the first lens 231a and the second lens 232a is changed from the first distance d1 to the second distance d2, the second protruding part 335 may slide with respect to the protrusion 342a-1 among the plurality of first protrusions 342a, by moving from the groove 341a-1 among the plurality of first grooves 341a in the first direction (e.g., +x direction). When the distance between the first lens 231a and the second lens 232a is changed from the first distance d1 to the second distance d2, the second protruding part 335 may be positioned outside the plurality of first grooves 341a by sliding with respect to the protrusion 342a-1 among the plurality of first protrusions 342a. When the distance between the first lens 231a and the second lens 232a is the second distance d2, as the second flange part 334 is deformed in a direction (e.g., −z direction) away from the plurality of first protrusions 342a, the second protruding part 335 may be positioned outside the plurality of first grooves 341a. When the distance between the first lens 231a and the second lens 232a is the second distance d2, the engagement between the second protruding part 335 and (any one of) the plurality of first protrusions 342a may be released.

[0149] As described above, according to an embodiment, the electronic device 101 may provide a structure in which a distance between the first lens 231a and the second lens 232a may be precisely adjusted by the first protruding part 332 and the second protruding part 335, which are misaligned with each other.

[0150] FIG. 10 is a perspective view illustrating a first adjusting structure and a second adjusting structure, according to an embodiment.

[0151] The first adjusting structure 330 of FIG. 10 may be a structure in which the structure of the first adjusting structure 330 of FIG. 8A is changed, so redundant descriptions will be omitted.

[0152] The second adjusting structure 340 of FIG. 10 may be a second adjusting structure in which the structure of the second adjusting structure 340 of FIG. 8B is changed, so redundant descriptions will be omitted.

[0153] Referring to FIG. 10, according to an embodiment, the first adjusting structure 330 may be deformable. For example, the first flange part 331 and the first protruding part 332 may be formed by a plate, which is to be bent. For example, the second flange part 334 and the second protruding part 335 may be formed by a plate, which is to be bent.

[0154] According to an embodiment, the first flange part 331 may include a first deformation groove 331a. The first deformation groove 331a may be formed at a position where a plate forming the first flange part 331 and the first protruding part 332 is bent. For example, the first deformation groove 331a may be surrounded (or covered) by the first protruding part 332. A shape of the first deformation groove 331a may be changed according to deformation of the first flange part 331.

[0155] According to an embodiment, the second flange part 334 may include a second deformation groove 334b. The second deformation groove 334b may be formed in a position where a plate forming the second flange part 334 and the second protruding part 335 is bent. For example, the second deformation groove 334b may be surrounded (or covered) by the second protruding part 335. A shape of the second deformation groove 334b may be changed according to deformation of the second flange part 334.

[0156] According to an embodiment, the second adjusting structure 340 may be deformable. For example, the second adjusting structure 340 may be formed by a plate, which is to be bent. For example, the second adjusting structure 340 may be transformable along a direction (e.g., +y direction) approaching to the first adjusting structure 330 and/or a direction (e.g., −y direction) away from the first adjusting structure 330.

[0157] FIG. 11A is a cross-sectional view illustrating a relationship between a first adjusting structure and a second adjusting structure when a distance between a first lens and a second lens is a first distance, according to an embodiment. FIG. 11B is a cross-sectional view illustrating a relationship between a first adjusting structure and a second adjusting structure when a distance between a first lens and a second lens is a second distance, according to an embodiment.

[0158] FIGS. 11A and 11B illustrate a relationship between the first adjusting structure 330 of FIG. 10 and the second adjusting structure 340 of FIG. 10, based on a distance between a first lens (e.g., the first lens 231a of FIG. 2B) and a second lens (e.g., the second lens 232a of FIG. 2B).

[0159] Referring to FIG. 11A, according to an embodiment, when the distance between the first lens 231a and the second lens 232a is a first distance (e.g., the first distance d1 of FIG. 4A), as the first flange part 331 is deformed by a contact between the protrusion 342a-1 among a plurality of the first protrusions 342a and a part of the first protruding part 332, a part of the first protruding part 332 may be positioned outside the plurality of first grooves 341a. For example, when the distance between the first lens 231a and the second lens 232a is the first distance d1, the first flange part 331 may be deformed in a direction (e.g., −z direction) away from the plurality of first protrusions 342a, by a contact between the protrusion 342a-1 among the plurality of first protrusions 342a and the first protruding part 332. The second adjusting structure 340 may be deformed by a contact with a part of the first protruding part 332. For example, the second adjusting structure 340 may be deformed in a direction away from the first protruding part 332, by a contact with a part of the first protruding part 332.

[0160] According to an embodiment, when the distance between the first lens 231a and the second lens 232a is the first distance d1, a part of the second protruding part 335 may be positioned (or accommodated) inside the groove 341a-1 among the plurality of first grooves 341a. When the distance between the first lens 231a and the second lens 232a is the first distance d1, a part of the second protruding part 335 may be positioned between the plurality of first protrusions 342a.

[0161] According to an embodiment, as the first lens support 231 moves with respect to the second lens support 232 in a first direction (e.g., +x direction), the distance between the first lens 231a and the second lens 232a may be changed from the first distance d1 to the second distance d2.

[0162] Referring to FIG. 11B, according to an embodiment, when the distance between the first lens 231a and the second lens 232a is the second distance d2, a part of the first protruding part 332 may be positioned (or accommodated) inside the groove 341a-1 among the plurality of first grooves 341a. For example, when the distance between the first lens 231a and the second lens 232a is changed from the first distance d1 to the second distance d2, a part of the first protruding part 332 may move toward the inside of a groove 341a-1 among the plurality of first grooves 341a, by sliding to the protrusion 342a-1 among the plurality of first protrusions 342a. For example, when the distance between the first lens 231a and the second lens 232a is the second distance d2, a part of the second protruding part 335 may be engaged with (any one of) the plurality of first protrusions 342a.

[0163] According to an embodiment, when the distance between the first lens 231a and the second lens 232a is the second distance d2, a part of the second protruding part 335 may be positioned outside the plurality of first grooves 341a. For example, when the distance between the first lens 231a and the second lens 232a is the second distance d2, as the second flange part 334 is deformed by a contact with the second adjusting structure 340, a part of the second protruding part 335 may be positioned outside the plurality of first grooves 341a. For example, when the distance between the first lens 231a and the second lens 232a is the second distance d2, the second flange part 334 may be deformed in a direction (e.g., −z direction) away from the plurality of first protrusions 342a, by a contact between another protrusion 342a-2 among the plurality of first protrusions 342a and a part of the second protruding part 335. When the distance between the first lens 231a and the second lens 232a is the second distance d2, as the second flange part 334 is deformed in a direction (e.g., −z direction) away from the plurality of first protrusions 342a, a part of the second protruding part 335 may be positioned outside the plurality of first grooves 341a. When the distance between the first lens 231a and the second lens 232a is the second distance d2, the engagement between a part of the second protruding part 335 and (any one of) the plurality of first protrusions 342a may be released.

[0164] As described above, according to an embodiment, the electronic device (e.g., the electronic device 101 of FIGS. 2A, 2B, and 2C) may provide a structure in which a distance between the first lens 231a and the second lens 232a may be precisely adjusted by the first protruding part 332 and the second protruding part 335 which are misaligned with each other.

[0165] FIG. 12A is a cross-sectional view illustrating a relationship between a first adjusting structure and a second adjusting structure when a distance between a first lens and a second lens is a first distance, according to an embodiment. FIG. 12B is a cross-sectional view illustrating a relationship between a first adjusting structure and a second adjusting structure when a distance between a first lens and a second lens is a second distance, according to an embodiment.

[0166] The first adjusting structure 330 of FIGS. 12A and 12B may be an adjusting structure in which the structure of the first adjusting structure 330 of FIGS. 4A and/or 4B is changed, so redundant descriptions will be omitted.

[0167] The second adjusting structure 340 of FIGS. 12A and 12B may be an adjusting structure in which the structure of the second adjusting structure 340 of FIGS. 4A and/or 4B is changed, so redundant descriptions will be omitted.

[0168] Referring to FIGS. 12A and 12B, according to an embodiment, the first adjusting structure 330 may be coupled to the first lens support 231 and the second lens support 232. For example, the first flange part 331, the first protruding part 332, and the first opening 333 of the first adjusting structure 330 may be coupled to the first lens support 231. The second flange part 334, the second protruding part 335, and the second opening 336 of the first adjusting structure 330 may be coupled to the second lens support 232. The first flange part 331, the first protruding part 332, and the first opening 333 may be movable together with the first lens support 231. For example, the first flange part 331, the first protruding part 332, and the first opening 333 may be movable together with the first lens support 231, independently of the second lens support 232, by being coupled to the first lens support 231 movable independently of the second lens support 232. The second flange part 334, the second protruding part 335, and the second opening 336 may be movable together with the second lens support 232. For example, the second flange part 334, the second protruding part 335, and the second opening 336 may be movable together with the second lens support 232, independently of the first lens support 231, by being coupled to the second lens support 232 movable independently of the first lens support 231.

[0169] According to an embodiment, the second adjusting structure 340 may be disposed on the supporting member 310. The second adjusting structure 340 may be formed (or defined) in the supporting member 310. For example, as shown in FIG. 12A, the second adjusting structure 340 may include a plurality of third grooves 341c, a plurality of fourth grooves 341d, a plurality of third protrusions 342c, and a plurality of fourth protrusions 342d.

[0170] According to an embodiment, the plurality of third grooves 341c may be arranged with respect to the first protruding part 332. For example, the plurality of third grooves 341c may be arranged to be spaced apart from each other along a first direction (e.g., +x direction) or a second direction (e.g., −x direction). For example, the plurality of third grooves 341c may face the first protruding part 332.

[0171] According to an embodiment, the plurality of fourth grooves 341d may be arranged with respect to the second protruding part 335. For example, the plurality of fourth grooves 341d may be arranged to be spaced apart from each other along the first direction (e.g., +x direction) or the second direction (e.g., −x direction). For example, the plurality of fourth grooves 341d may face the second protruding part 335. According to an embodiment, the plurality of fourth grooves 341d may be spaced apart from the plurality of third grooves 341c. For example, the plurality of fourth grooves 341d may be spaced apart from the plurality of third grooves 341c along the second direction (e.g., −x direction). For example, a part of the supporting member 310 in which the plurality of fourth grooves 341d are formed may be spaced apart from another part of the supporting member 310 in which the plurality of third grooves 341c are formed along the second direction (e.g., −x direction).

[0172] According to an embodiment, the plurality of third protrusions 342c may be disposed between the plurality of third grooves 341c. The plurality of third protrusions 342c may be arranged with respect to the first protruding part 332. The plurality of third protrusions 342c may be spaced apart from each other. For example, the plurality of third protrusions 342c may be arranged to be spaced apart from each other along the first direction (e.g., +x direction) or the second direction (e.g., −x direction).

[0173] According to an embodiment, the plurality of fourth protrusions 342d may be disposed between the plurality of fourth grooves 341d. The plurality of fourth protrusions 342d may be arranged with respect to the second protruding part 335. The plurality of fourth protrusions 342d may be spaced apart from each other. For example, the plurality of fourth protrusions 342d may be arranged to be spaced apart from each other in the first direction (e.g., +x direction) or the second direction (e.g., −x direction).

[0174] Referring to FIG. 12A, according to an embodiment, when a distance between a first lens (e.g., the first lens 231a of FIG. 2B) and a second lens (e.g., the second lens 232a of FIG. 2B) is a first distance (e.g., the first distance d1 of FIG. 4A), the first protruding part 332 may be positioned (or accommodated) inside the groove 341c-1 among the plurality of third grooves 341c. For example, when the distance between the first lens 231a and the second lens 232a is the first distance d1, the first protruding part 332 may be engaged with (any one of) the plurality of third protrusions 342c.

[0175] According to an embodiment, when the distance between the first lens 231a and the second lens 232a is the first distance d1, the second protruding part 335 may be positioned outside the plurality of fourth grooves 341d. For example, when the distance between the first lens 231a and the second lens 232a is the first distance d1, the second protruding part 335 may be positioned outside the plurality of fourth grooves 341d by a contact with the second adjusting structure 340 (or the supporting member 310). When the distance between the first lens 231a and the second lens 232a is the first distance d1, the engagement between the second protruding part 335 and (any one of) the plurality of fourth protrusions 342d may be released.

[0176] According to an embodiment, as the first lens support 231 moves with respect to the second lens support 232 in the first direction (e.g., +x direction), the distance between the first lens 231a and the second lens 232a may be changed from the first distance d1 to a second distance (e.g., the second distance d2 of FIG. 4B).

[0177] Referring to FIG. 12B, according to an embodiment, when the distance between the first lens 231a and the second lens 232a is the second distance d2, the first protruding part 332 may be positioned outside the plurality of third grooves 341c. For example, when the distance between the first lens 231a and the second lens 232a is the second distance d2, the first protruding part 332 may be positioned outside the plurality of third grooves 341c by contacting with a protrusion 342c-1 of the plurality of third protrusions 342c. For example, when the distance between the first lens 231a and the second lens 232a is the second distance d2, the engagement between the first protruding part 332 and the plurality of third protrusions 342c may be released.

[0178] According to an embodiment, when the distance between the first lens 231a and the second lens 232a is the second distance d2, the second protruding part 335 may be positioned outside the plurality of fourth grooves 341d. For example, since the second protruding part 335 and the first protruding part 332 may move independently from each other, a relationship between the second protruding part 335 and the plurality of fourth grooves 341d (when the distance between the first lens 231a and the second lens 232a is the second distance d2) may be substantially the same as a relationship between the second protruding part 335 and the plurality of fourth grooves 341d (when the distance between the first lens 231a and the second lens 232a is the first distance d1).

[0179] According to an embodiment, as the second lens support 232 moves with respect to the first lens support 231 in a second direction (e.g., −x direction), the distance between the first lens 231a and the second lens 232a may be changed from the second distance d2 to a third distance that is different from the first distance d1 or the second distance d2. When the distance between the first lens 231a and the second lens 232a is the third distance, the second protruding part 335 may be positioned (or accommodated) inside the groove 341d-1 among the plurality of fourth grooves 341d. A relationship between the first protruding part 332 and the plurality of third grooves 341c (when the distance between the first lens 231a and the second lens 232a is the third distance) may be substantially the same as a relationship between the first protruding part 332 and the plurality of third grooves 341c (when the distance between the first lens 231a and the second lens 232a is the second distance d2).

[0180] As described above, according to an embodiment, since the first protruding part 332 (which is movable with respect to the plurality of third grooves 341c) is movable independently of the second protruding part 335 (which is movable with respect to the plurality of fourth grooves 341d), the electronic device 101 may provide a structure in which the distance between the first lens 231a and the second lens 232a may be precisely adjusted.

The first flange part 331, the first protruding part 332, and the first opening 333 may be fastened to the supporting member 310. For example, positions of each of the first flange part 331, the first protruding part 332, and the first opening 333 with respect to the supporting member 310 may be maintained when the first lens support 231 and the second lens support 232 move with respect to the supporting member 310. The first flange part 331 may be disposed on at least one of the first rack gear 231b and the second rack gear 232b. For example, the first flange part 331 may be disposed on the second rack gear 232b, but the first flange part 331 is not limited thereto.

The second flange part 334 may be disposed on the first flange part 331. For example, the first flange part 331 may be disposed (or interposed) between the second rack gear 232b and the second flange part 334. The second protruding part 335 may be stacked on the first protruding part 332 to be misaligned with the first protruding part 332.

For example, the plurality of fifth grooves 341e may be arranged to be spaced apart from each other along a circumferential direction of the pinion gear 320.

[0188] According to an embodiment, the plurality of sixth grooves 341f may be arranged with respect to the second protruding part 335. For example, the plurality of sixth grooves 341f may be arranged to be spaced apart along the rotation direction (e.g., the first rotation direction r1 in FIG. 4A and/or the second rotation direction r2 in FIG. 4B) of the pinion gear 320. For example, the plurality of sixth grooves 341f may be arranged to be spaced apart along the circumferential direction of the pinion gear 320.

For example, the plurality of sixth protrusions 342f may be arranged to be spaced apart along the circumferential direction of the pinion gear 320. The plurality of sixth protrusions 342f may be disposed between the plurality of sixth grooves 341f.

For example, the plurality of fifth grooves 341e and the plurality of fifth protrusions 342e may be formed on the first adjusting member 343. The first adjusting member 343 may be disposed on the pinion gear 320. The first adjusting member 343 may be rotatable with the pinion gear 320 by rotation of the pinion gear 320. The first adjusting member 343 may not be engaged with the first rack gear 231b and the second rack gear 232b. For example, a rotation direction of the first adjusting member 343 may be substantially the same as a rotation direction of the pinion gear 320. For example, the first adjusting member 343 may be coupled to a rotation shaft 320a of the pinion gear 320.

For example, the first adjusting member 343 may be disposed (or interposed) between the second adjusting member 344 and the pinion gear 320.

[0193] Referring to FIG. 13A, according to an embodiment, when a distance between a first lens (e.g., the first lens 231a of FIG. 2B) and a second lens (e.g., the second lens 232a of FIG. 2B) is a first distance (e.g., the first distance d1 of FIG. 4A), the first protruding part 332 may be positioned (or accommodated) inside a groove 341e-1 among the plurality of fifth grooves 341e. When the distance between the first lens 231a and the second lens 232a is the first distance d1, the first protruding part 332 may be positioned between the plurality of fifth protrusions 342e. For example, when the distance between the first lens 231a and the second lens 232a is the first distance d1, the first protruding part 332 may be engaged with the plurality of fifth protrusions 342e.

When the distance between the first lens 231a and the second lens 232a is the second distance d2, the second protruding part 335 may be positioned between the plurality of sixth protrusions 342f. For example, when the distance between the first lens 231a and the second lens 232a is the second distance d2, the second protruding part 335 may be engaged with the plurality of sixth protrusions 342f.

[0198] According to an embodiment, as the first lens support 231 moves in the second direction (e.g., −x direction) with respect to the second lens support 232, the pinion gear 320 may rotate in the second rotation direction r2. The first adjusting member 343 and the second adjusting member 344 may rotate along the second rotation direction r2, by the rotation of the pinion gear 320 in the second rotation direction r2. As the pinion gear 320 rotates in the second rotation direction r2, the distance between the first lens 231a and the second lens 232a may be changed from the second distance d2 to the first distance d1.

[0199] As described above, according to an embodiment, as a relative position of the first protruding part 332 and the second protruding part 335 with respect to the plurality of grooves 341e and 341f that rotate according to a rotation of the pinion gear 320 when the pinion gear 320 rotates are changed, the electronic device 101 may provide a structure in which a distance between the first lens 231a and the second lens 232a may be precisely changed.
