Description
Background of the Invention
1. Field of the Invention
This invention relates to an information processing apparatus such as a notebook-type personal computer, a word processor, and so forth. More particularly, it relates to an information processing apparatus having a thin structure.
As the portability of an information processing apparatus, such as a portable computer, has been improved in recent years, a small thickness has been required. Therefore, an information processing apparatus having a small thickness must be provided.
2. Related Art
In conventional information processing apparatuses, internal modules and units that constitute an information processing apparatus are disposed as portions in superposition with one another in the direction of height. For example, a built-in battery and a built-in hard disk drive (HDD) are disposed below a keyboard module or a main board. In the conventional information processing apparatus, an upward connector is disposed on the surface of the main board facing the keyboard module. When two PC card slots are provided to the conventional information processing apparatus, they are disposed in a stack form in the direction of height.
As examples of the prior art references, Japanese Unexamined Patent Publication (Kokai) Nos. 8-76887 and 8-76898 describe an information processing apparatus having a reduced thickness structure. Japanese Unexamined Patent Publication (Kokai) No. 8-76885 discloses an information processor equipped with speakers mounted to a substrate for peripheral processing and for a speaker, and Japanese Unexamined Patent Publication (Kokai) No. 8-76886 discloses a structure wherein a cover casing to which a liquid crystal display is fitted is provided with a reduced thickness.
As described above, the thickness of the information processing apparatus of the prior art is the sum of the height of respective internal modules disposed in superposition with one another, and becomes greater than the height of each internal module by the superposition thickness. Further, a gap is necessary between the main board and the keyboard module so that the connector and cables can be disposed inside it. Further, when two PC card slots are installed, the thickness becomes greater than when one PC card slot is disposed.
Summary of the Invention
It is therefore an object of the present invention to provide an information processing apparatus which further promotes the reduction of thickness and improves portability.
According to the present invention, there is provided a thin structure information processing apparatus comprising: a body of the information processing apparatus, the body having a substantially planar structure and accommodating therein at least a main board; a power supply board; a built-in battery; a built-in hard disk drive; and the main board, the power supply board, the built-in battery and the built-in hard disk drive being arranged in such a manner they are not imposed relatively to each other and with respect to a major plane of the substantially planar structure.
In another aspect of the present invention, there is provided a thin structure information processing apparatus comprising: a body of the information processing apparatus, the body having a substantially planar structure and accommodating therein at least a main board; a power supply board; a built-in battery; a built-in hard disk drive; and the main board, the power supply board, the built-in battery and the built-in hard disk drive being arranged in such a manner they are not imposed each other with respect to a plane of the substantially planar structure; the body further comprising: a key board module; a palm rest; and the built-in battery and the a built-in hard disk drive are arranged in such a manner that they do not occupy a space under the key board module.
The main board is provided with at least one connector projecting upward from an upper surface of the main board and the connector is arranged at a position other than an area where the main board and the key board module are imposed.
The main board and the key board module are arranged substantially in parallel to each other so that a gap is defined between the main board and the key board module and the body has at least two PC-card slots which are arranged in such a manner that these PC-card slots are not mutually imposed with respect to each other, but they are located within the gap.

Description of the Preferred Embodiments
Hereinafter, information processing apparatuses according to preferred embodiments of the present invention will be explained in detail with reference to the accompanying drawings.
FIG. 1 is a plan view showing the disposition and construction of internal modules within an interior of the information processing apparatus according to the present invention, and FIG. 2 is a perspective view when the disposition and construction is viewed from the oblique direction. In the drawings, reference numeral 1 denotes a main body of an information processing apparatus, reference numeral 2 denotes a main board, reference numeral 3 denotes a power supply board, reference numeral 4 denotes a built-in battery, reference numeral 5 denotes a built-in HDD (hard disk drive), reference numeral 6 denotes a keyboard module, reference numeral 7 denotes a palm rest, reference numeral 8 denotes a pointing device, and reference numeral 10 denotes a PC-card slot. As shown in FIG. 1, the main board 2 is positioned in a wide rear area of the interior away from the side of an operator (not shown). The power supply board 3 is disposed at the center of the front part of the main board 2, the built-in battery 4 is disposed on the right side and the built-in HDD 5 is disposed on the left side. Further, these members are so disposed within the interior as not to overlap with one another plane-wise (i.e., so as to be substantially not superimposed relatively to each other). Incidentally, the main board 2 and the built-in HDD 5 are connected by cables and a connectors 40p, and the power supply board 3 and the built-in battery 4 are connected by a cable and a connector 8p.
The built-in battery 4 and the built-in HDD 5 at the right and left sides of the front portion have a relatively large height, are not therefore disposed below the keyboard module 6 but are disposed below the palm rest 7 where the greatest height can be secured (see also FIG. 5). The power supply board 3 at the center of the front portion is lower than the built-in battery 4 and the built-in HDD 5, and is therefore disposed below the pointing device 8 for moving a cursor.
Since the main board 2 has a relatively small thickness, it is disposed in superposition with the keyboard module 6. As shown in FIG. 3, however, the upward connector 9 connected to the main board 2 is disposed at a position other than the overlapping position of the main board 2 with the keyboard module 6, such as at the front and rear end positions of the main board 2 deviated from the area of the keyboard module 6 as viewed from the side of the operator (not shown). Other electronic components (not shown) disposed on the main board 2 are far thinner than the connector 9. Therefore, even when they are disposed at overlapping positions with the keyboard module 6, the internal thickness of the information processing apparatus does not increase much as a whole. In consequence, the necessary internal thickness can be much reduced in comparison with the information processing apparatus according to the prior art (an example of which is shown in FIG. 6) wherein the connector 9 is disposed below the keyboard module 6.
By the way, the upward connector 9 may be disposed at any position of the main board 2 other than the overlapping position between the main board 2 and the keyboard module 6. For example, it can be disposed at the left end and/or at the right end of the main board 2.
FIG. 4 shows the positional relationship between the main board 2 and PC-card slots 10 when two cards for extending the functions, that is, two PC-card slots 10, are provided. As shown in this drawing, the two PC-card slots 10 are disposed at the right and left positions of the main board so as not to overlap with each other as viewed from the side of the operator (not shown). Each PC-card slot 10 is disposed between the main board 2 and the keyboard module 6 as shown in FIG. 2. Therefore, the operator can load the necessary PC-cards (not shown) from the right and left side surfaces of the information processing apparatus. Incidentally, though only one PC-card slot 10 is shown disposed on the right side in FIG. 2, two PC-card slots 10 can be disposed on both right and left sides. Furthermore, an additional PC-card slot may, of course, be disposed in addition to the right and left positions, if possible.
In order to further reduce the thickness and as shown in FIG. 8, the portion of the main board 20 corresponding to the disposition portion of the PC-card slot 10' may be cut off to define a notch portion 20, and each PC-card slot 10' can be disposed at this notch portion 20.
FIG. 7 shows the appearance of the information processing apparatus of the present invention in six views. The outer dimension of the information processing apparatus 1 of this invention is 297 mm width, 232 mm depth and 28.2 mm height, and the thickness can be thus reduced.
According to the present invention described above, the main board, the power supply board, the built-in battery and the built-in HDD are disposed in such a manner as not to overlap with one another, at portions other than the connector portions for connecting them, respectively. Therefore, the necessary internal thickness of the information processing apparatuses can be made smaller than that of the prior art apparatuses, and the present invention can contribute to the reduction of the thickness and to the improvement of portability of the information processing apparatus.
Because the built-in battery and the built-in HDD are not disposed below the keyboard module but are disposed below the palm rest portion where the greatest height can be secured, the present invention can contribute to the reduction of thickness of the information processing apparatus and to the improvement of its portability.
Because the upward connectors of the main board are disposed at the positions other than the position immediately below the keyboard module such as at the front end or the rear end when the main board is viewed from the front, the thickness of the apparatus can be reduced by the overlapping thickness with the keyboard module. Therefore, the present invention can contribute to the reduction of the thickness of the apparatus and to the improvement of its portability.
Furthermore, because the two PC-card slots are disposed so as not to be superposed in the direction of thickness, the provision of such PC-card slots does not invite an increase in the thickness but can contribute to the reduction of the thickness of the information processing apparatus and to the improvement of its portability.
It should be understood by those skilled in the art that the foregoing description relates to only a preferred embodiment of the disclosed invention, and that various changes and modifications may be made to the invention without departing from the spirit and scope thereof.
