DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the personal computer of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a PC main body 2 of a personal computer (PC) 1 according to an embodiment of the present invention as viewed from the rear side. Although not shown, a central processing unit, a storage device, and the like are mounted in the housing 3 of the PC main body 2. Although not shown, an input device such as a keyboard,
Output devices such as a CRT and a printer are connected. Data input from these input devices can be processed by a central processing unit or the like in the PC main body 2 and output to an output device.

Two additional boards can be mounted on the PC main body 2, and two first board openings 31 and second board openings 32 corresponding to positions where the respective extension boards are mounted. Is provided. These first and second board openings 31 and 32 are L-shaped with a width of several cm from the upper surface to the rear surface of the housing 3. Board openings 31, 3
2, a connector (not shown) for mounting an additional board is provided on the bottom surface in the PC main body 3.

The first and second board openings 31, 3
The second extension cover 2 is closed by an L-shaped first extension cover 4 and a second extension cover 5 having substantially the same width as these board openings. Since these additional covers 4 and 5 have the same structure, a side view of the additional cover 4 is typically shown in FIG. As shown in the figure, the additional cover 4 includes a cover portion 41 for closing the board opening 31 and a mounting portion 42 for mounting the additional board, and the mounting portion 42 is fixed to the inner surface side of the cover portion 41. I have.

The cover 41 has an upper surface 43 for closing the board opening 31 on the upper surface of the housing 3 and a rear surface 44 for closing the board opening on the rear surface of the housing 3. A in FIG.
FIG. 3 shows an example of a cross section of the cover portion 41 taken along the line A.

The cover 41a shown in FIG. 3A is made of a material such as rubber having elasticity, and has a fitting groove 44 formed along the center of the edge. Using the elasticity of the cover 41a, the fitting groove 4 is formed in the edge of the board opening 31 of the housing 3.
4 and the cover 41 is connected to the board opening 3 of the housing 3.
It is fixed to 1. When the cover 41a is removed from the board opening 31 of the housing 3 by lifting the cover 41a upward from one end side of the board opening 31, the cover 41a is deformed and the housing 3 is removed. Is released, and the cover 41a can be removed from the housing.

The cover 41b shown in FIG.
Is made of, for example, an elastic plastic material. The width of the cover portion 41b is equal to the board opening 3 of the housing 3.
1, and the edge of the cover 41b presses the edge of the housing 3 of the board opening 31 when the cover 41b is attached to the board opening 31. . An overhanging portion 46 is provided on an upper portion of the edge of the cover portion 41b so as to project laterally.
Functions as a stopper when attached to the board opening 31.

When the cover 41b is mounted on the board opening 31 of the housing 3, the board opening 3
By fitting the cover portion 41b into the cover portion 1,
1b fits into the board opening 31 and the stopper 46 allows the cover 41b to be accurately attached to the board opening 31.

On the rear surface of the cover 41, a discarding member 47 for opening a portion corresponding to the external interface of the extension board is formed integrally with the rear surface 44 of the cover via a notch 48 so as to be cut off. I have.

The mounting portion 42 is a member for mounting an extension board. FIG. 4 is a sectional view taken along the line BB in FIG.
Shown in The mounting portion 42 is fixed to the upper surface portion 43 of the cover portion by integral or bonding with the cover portion 43. A board groove 42a that fits with the upper end of the extension board is formed at the lower edge of the mounting section 42, and the extension board can be attached to the mounting section 42 by inserting the upper end of the extension board into the board groove 42a. It has become. Mounting part 42
Is a material having elasticity such as rubber and elastomer,
It is made of a flexible material such as plastic.

Next, a procedure for mounting an extension board on a PC having such an extension cover will be described with reference to FIGS.

First, the first and second PC main units shown in FIG.
One of the additional covers 4 and 5 is removed from the housing 3 of the PC body 2. In this case, since the additional covers 4 and 5 do not use attachment parts such as screws, no storage parts are generated when the extension covers 4 and 5 are removed from the housing 3.

Next, as shown in FIG. 5A, after the discarded member 47 of the removed additional cover 4 is cut off,
As shown in (b), the additional board 6 is fitted into the board groove 42a of the mounting portion 42. Then, as shown in FIG. 5C, with the additional board 6 attached to the additional cover 4, the additional board 6 is removed from the board opening 31 of the housing 3.
The connector 61 of the extension board 6 is connected to a connector (not shown) on the bottom surface of the main body 2, and the extension cover 4 is fitted into the board opening 31 of the housing 3 to close the board opening 31. .

As a result, as shown in FIG. 6, the extension board 6 is mounted on the PC body 2 and the board opening 3
1 can be closed by the additional cover 4 to prevent dust and the like from entering the main body. The rear surface of the board opening 31 of the PC body 2 is closed by the interface 62 with the outside of the additional board and the rear surface 44 of the additional cover.

As described above, according to the PC 1 of the present embodiment, the extension cover 4 can be easily removed from the PC main body 2, the extension board 6 is attached to the detached extension cover 4 with one touch, and the extension cover 4 is again attached to the PC. It can be performed by the work of fitting into the main body 2.

Therefore, it is possible to remove the time and labor of removing the roof cover with the screws and mounting the extension board, and then further fixing the roof cover with the screws, thereby saving time and labor by a simple operation. Can be. In addition, when mounting the extension board 6, since no fixing parts such as screws are used, there is no risk of losing the removed screws and the like.

In the above embodiment, the discarding member is formed integrally with the extension cover. However, the interface with the outside of the extension board can be closed by a cover member different from the extension cover. A cover disposable is not required.

The form of attachment of the additional cover to the housing is not limited to the above example. For example, one end of the additional cover may be rotatably attached to the housing, or a hinge may be used. May be fitted together.

[0032]

As described above, according to the personal computer of the present invention, the extension board can be mounted by a simple operation, and the time and labor for mounting the extension board can be saved.
