The disk drive 11 is fitted into the disk drive 2. In this case, the width of the disk drive 11 in the Y direction is set equal to the inner width of the shield plate 12 in the Y direction. Then, the other shield plate 13 is placed on the disk drive 11. The shield plate 13 has the same shape and dimensions as the shield plate 12, and the upper surface of the disk drive 11 fits into the shield plate 13. Thus, the upper, lower, and both sides of the disk drive 11 are covered with the shield plates 12 and 13.

In the state as described above, the front case 3 with the door 6 attached is fitted into the front frame 2c of the lower case 2, and the rear case 10 is attached to the rear end of the lower case 2. Then, the upper case 1 is placed on them. The upper case 1 has a frame 1a having a narrow width all around its circumference.
And the upper edge of the rear case 10 fits. Further, a protruding portion 1b is provided to protrude from the frame 1a of two opposing sides (one not shown) of the upper case 1, and when the upper case 1 is attached as described above, these protruding portions are provided. 1b faces the protrusion 2d of the lower case 2.

FIG. 6 shows such a state, in which the outer side surface of the frame 1a of the upper case 1 and the side frame 2b of the lower case 2 are shown.
Are on the same plane as the outer side surface of the upper case 1, but the outer side surface of the protrusion 1b of the upper case 1 and the outer side surface of the protrusion 2d of the lower case 2 are on another plane inside the plane. is there.
For this reason, a strip-shaped concave area C in the depth direction of the housing is formed by the outer side surfaces of the protruding portions 1b and 2d. The height width of the recess area C is equal to the width of the side piece 4,
The side piece 4 is fitted into the recess area C.

In the state shown in FIG. 6, the side pieces 4 are fitted into the recessed areas C on both sides of the upper case 1 and the lower case 2, and the locking pieces 15 provided on the side pieces 4 And the lower case 2. As a result, the upper case 1 and the lower case 2 are connected via the side pieces 4, and the disk drive 11 and the shield case 1 are connected.
A housing in which 2, 13 are built is completed. In the above description, the storage components other than the disk drive 11 and the shield cases 12 and 13 are omitted.

Here, the attachment of the side piece 4 will be described.

On the inner surface of the side piece 4, a locking hole 14 provided in the projection 1b of the upper case 1 and a lower case 2
The hook-shaped locking pieces 15 are provided so as to face the locking holes 14 provided in the projecting portion 2d of the lower case 2, respectively. When the drive 11, the front case 3, the rear case 10, and the upper case 1 are installed, the locking pieces 15 are attached to the upper case 1, the lower case 1 by attaching the side pieces 4 to the recessed areas C (FIG. 6). 2 can be inserted into the locking holes 14 provided in the second. After inserting the locking pieces 15 into the locking holes 14 in this manner, the side pieces 4
Is slid along the recessed area C (FIG. 6) in a direction corresponding to the shape of the locking piece 15 (here, the X direction, that is, the direction of the front frame 2c of the lower case 2), thereby locking. The piece 15 is locked in the locking hole 14, and the side piece 4 is fixed. This also allows the upper case 1 and the lower case 2
Are connected via the side piece 4. Further, a bent portion 4a formed at the rear end of the side piece 4 holds the rear case 10 from the rear. In order to prevent the side piece 4 from easily sliding in the opposite direction after the assembly of the housing, a screw 1 is provided on the rear case 10 side.
8, the rear end of the side piece 4 is screwed to the protruding portion 2d of the lower case 2.

Further, as shown in FIG.
7A, the locking holes 14 provided in the projecting portion 2d of the lower case 2 and the projecting portion 1b of the upper case 1 are aligned in the horizontal direction (that is, in the side piece 4). It has a rectangular shape elongated in the slide direction (X direction). Here, the lateral length (hereinafter, simply referred to as the length) of the locking hole 14 is L, and the length in the direction perpendicular to this is (L). Hereinafter, the width is referred to as h. The thickness of the protrusion 2d of the lower case 2 and the protrusion 1b of the upper case 1 is d.

On the other hand, the locking piece 15 provided on the side piece 4 has a hook shape, but its lateral length L ′ is slightly smaller than the length L of the locking hole 14. The thickness h ′ of the locking piece 15 is also slightly smaller than the width h of the locking hole 14. The distance d 'between the hook-shaped bent portion of the locking piece 15 (the portion parallel to the surface of the side piece 4) and the surface of the side piece 4 is substantially equal to the thickness d of the protruding portions 1b and 2d.

Since the locking piece 15 and the locking hole 14 are configured as described above, the locking piece 15 can be inserted into the locking hole 14, and in this state, the side piece 4
As shown in FIG. 7 (b), it comes into contact with the outer surfaces of the protrusions 1b and 2d in the recessed area C shown in FIG. When the side piece 4 is slid in the X direction in such a state, as shown in FIG.
The projections 1b and 2d are fitted between this portion and the surface of the side piece 4, so that the locking pieces 15 do not come out of the locking holes 14. As a result, the side piece 4 is connected to the upper case 1 and the lower case 2, so that the upper case 1 and the lower case 2 are connected via the side piece 4.

FIG. 8 shows the thus assembled FIG.
2 is a cross-sectional view of the housing taken along the section line AA, and the same reference numerals are given to portions corresponding to the preceding drawings.

In the same figure, the locking piece 1 of the side piece 4
The case 5 is locked in the locking holes 15 of the upper case 1 and the lower case 2, whereby the cases 1 and 2 are connected via the side pieces 4, thereby forming a housing. In this case, since the side frame 2b of the lower case 2 is higher than the side frame 1a of the upper case 1, the side piece 4 is located on the upper side of the side of the housing.
That is, it is arranged to be offset toward the upper case 1 side.
Now, if the center in the width direction of the side piece 4 attached to the housing is indicated by a dashed line D, the height dimension H _{0 of the} center D is shown.
Has a relationship of H ₀ > H / 2 with respect to the height H of the housing.

By arranging the side pieces in this manner, a wide area of the side frame 2b of the lower case 2 is exposed to the outside, and a sufficient area for providing the heat radiation holes 7 (FIG. 1) is secured. In addition, a space for the leg portion 8 to be provided from the outer bottom surface to the side surface of the lower case 2 can be obtained.

The boundary between the protruding portion 1b of the upper case 1 and the protruding portion 2d of the lower case 2 is opposed to the center D of the side piece 4, so that these protruding portions 1b, 2
Even if there is a gap between the leading ends of the projections d, they are blinded by the side pieces 4, so that the accuracy of the heights of the projections 1b and 2d can be reduced.

As described above, in this embodiment, the screws 18 (FIG. 4) are used to prevent the side pieces 4 from coming off.
It is possible to assemble the housing with almost no screws except for using the screws, and to fix the upper case 1 and the lower case 2 with the side pieces 4.
It is only necessary to insert the locking pieces 15 into the locking holes 15 of these cases 1 and 2 and slide the side piece 4, and the assembly work of the housing is extremely difficult as compared with the conventional method of fixing using screws. It's easy. Also, when disassembling the housing to replace the storage parts, it is only necessary to remove the screws 18 screwing the side pieces and slide the side pieces 4, and the disassembly work is very simple. Becomes

Furthermore, the amount of protrusion of the locking piece 15 from the inner surface of the side piece 4 is small, and wasteful space is reduced as compared with a conventional case in which each part is fixed using screws. Therefore, the internal volume of the housing can be reduced and the size of the device can be reduced.
