[0027] FIG. 9 is a schematic operational view of the disc storage box having a disc positioning device as shown in FIG. 7.

[0028] Referring to the drawings and initially to FIGS. 4-7, a disc storage box having a disc positioning device in accordance with a preferred embodiment of the present invention comprises a main body 51, and a disc positioning device 50 integrally formed on the main body 51.

[0029] The disc positioning device 50 includes a placing portion 60, a plurality of insertion portions 70, and a locking portion 80.

[0030] The placing portion 60 of the disc positioning device 50 has a circular shape, and is formed on and protruded from the main body 51. The placing portion 60 of the disc positioning device 50 has an inner periphery formed with a support flange 61.

[0031] Each of the plurality of insertion portions 70 of the disc positioning device 50 has a concave shape, and is formed on the placing portion 60. Each of the plurality of insertion portions 70 of the disc positioning device 50 is formed with an arcuate support plte 71.

[0032] The locking portion 80 of the disc positioning device 50 is formed on the center of the placing portion 60. The locking portion 80 of the disc positioning device 50 has an outer periphery formed with an annular lug 81 and an inner periphery formed with a plurality of arcuate hook slots 82. The locking portion 80 of the disc positioning device 50 has a central portion formed with a protruding locking knob 83 which has a top formed with a press face 84. The locking knob 83 of the locking portion 80 of the disc positioning device 50 has a periphery formed with a plurality of insertion blocks 85 and a plurality of locking arms 86 arranged in a staggered manner.

[0033] The periphery of the locking knob 83 of the locking portion 80 of the disc positioning device 50 is formed with a plurality of gaps 87 each located between each of the insertion blocks 85 and each of the locking arms 86. Each of the insertion blocks 85 of the locking knob 83 of the locking portion 80 of the disc positioning device 50 is formed with a slit 851 which is extended outward and connected to one of the hook slots 82 of the locking portion 80. Each of the locking arms 86 of the locking knob 83 of the locking portion 80 of the disc positioning device 50 is formed with a protruding boss 88. Each of the locking arms 86 of the locking knob 83 of the locking portion 80 of the disc positioning device 50 has a top formed with an oblique arcuate guide face 861 located adjacent to the press face 84.

[0034] In operation, referring to FIGS. 6 and 7 with reference to FIGS. 4 and 5, the positioning hole 91 of the disc 90 is mounted on the locking knob 83 of the locking portion 80 of the disc positioning device 50. Then, the user slightly exerts a force to press the press face 84 of the locking knob 83. At this time, the insertion blocks 85 and the locking arms 86 of the locking knob 83 are separated by the gaps 87, and each of the insertion blocks 85 is formed with a slit 851 extended outward and connected to one of the hook slots 82. Thus, when the press face 84 of the locking knob 83 is pressed downward, the locking arms 86 are retracted inward and downward, so that the locking knob 83 is retracted inward, thereby shortening the diameter of the locking knob 83, so that the diameter of the locking knob 83 is smaller than that of the positioning hole 91 of the disc 90. Thus, the wall of the positioning hole 91 of the disc 90 is easily moved downward to pass through the protruding boss 88 of each of the locking arms 86 by guidance of the oblique arcuate guide face 861 of each of the locking arms 86.

[0035] After the pressing force applied on the press face 84 of the locking knob 83 is removed, the locking knob 83 is expanded outward by its restoring force, so that the wall of the positioning hole 91 of the disc 90 is locked on the locking knob 83 by the protruding boss 88 of each of the locking arms 86. In such a manner, the disc 90 is placed in the placing portion 60, and is supported by the support flange 61 of the placing portion 60. In addition, the support plate 71 of each of the plurality of insertion portions 70 provides an auxiliary positioning effect on the disc 90.

[0036] Thus, the disc 90 is actually mounted on the locking knob 83 easily and conveniently. In addition, the disc 90 is exactly locked on the locking knob 83 stably and rigidly, thereby preventing from detachment of the disc 90 due to a violent vibration or shock.

[0037] On the other hand, referring to FIGS. 8 and 9 with reference to FIGS. 4 and 5, when the user wishes to remove the disc 90 out of the locking knob 83, the user slightly exerts a force to press the press face 84 of the locking knob 83. At this time, the insertion blocks 85 and the locking arms 86 of the locking knob 83 are separated by the gaps 87, and each of the insertion blocks 85 is formed with a slit 851 extended outward and connected to one of the hook slots 82. Thus, when the press face 84 of the locking knob 83 is pressed downward, the locking arms 86 are retracted inward and downward, so that the locking knob 83 is retracted inward, thereby shortening the diameter of the locking knob 83, so that the diameter of the locking knob 83 is smaller than that of the positioning hole 91 of the disc 90. Thus, the wall of the positioning hole 91 of the disc 90 is easily detached from the protruding boss 88 of each of the locking arms 86, so that the disc 90 is detached from the locking knob 83 easily and conveniently.

[0038] In addition, each of the plurality of insertion portions 70 of the disc positioning device 50 has a concave shape, thereby facilitating the user removing the disc 90 from the placing portion 60.

[0039] Accordingly, the disc 90 is actually mounted on the locking knob 83 easily and conveniently. In addition, the disc 90 is exactly locked on the locking knob 83 stably and rigidly, thereby preventing from detachment of the disc 90 due to a violent vibration or shock. Further, the disc 90 is detached from the locking knob 83 easily and conveniently.

[0040] While the preferred embodiment(s) of the present invention has been shown and described, it will be apparent to those skilled in the art that various modifications may be made in the embodiment(s) without departing from the spirit of the present invention. Such modifications are all within the scope of the present invention.
