Are attached, and the supported pin 100 is attached at a position near the front end at the left end (see FIGS. 33 and 34). These supported pins 100, 100, 100
Originally, it is attached to a screw hole formed for attaching the optical disk drive 98 to the chassis.

The supported pin 100 has an outer flange portion 100b and an inner flange portion 100c located on opposite sides of the shaft portion 100a, and an optical disk is provided via a screw (not shown) projecting from the inner flange portion 100c. It is attached to the drive 98. The width of the guide grooves 73 and 74 provided in the chassis 56 is slightly larger than the diameter of the outer flange portion 100b of the supported pin 100 attached to the optical disk drive 98. Further, the width of the slit formed in the falling-off preventing pieces 73a, 73b, 74a provided in the guide grooves 73, 74 is
It is substantially the same as the shaft portion 100a of the supported pin 100.

In the upper surface 98b of the optical disk drive 98, insertion holes 101, 101,.
Are formed, and the insertion holes 101, 101,...
Is originally formed as a screw hole for attaching the optical disk drive 98 to the chassis.

The optical disk drive 98 is mounted on the chassis 56 as follows.

First, the optical disk drive 98 is inserted from the front into the drive insertion opening 60a formed in the front support portion 60 of the chassis 56, and the supported pins 100, 1 attached to the upper end of the right side surface 98a of the optical disk drive 98 are inserted.
00 is inserted into the guide groove 73 of the chassis 56 from the front. At this time, as described above, since the front end of the guide groove 73 is formed as the introduction portion 73c in which the groove width is gradually increased as going forward, the supported pin 100,
100 can be easily inserted.

The supported pins 100, 100 are inserted into the guide grooves 73.
Into the optical disk drive 98
b is slidably contacted with the insertion pin 78 inserted into the regulating protrusion 77 of the upper surface support 59, and the regulating protrusion 77 is elastically displaced in the direction in which the tip moves upward. When the rear supported pin 100 is inserted to the end of the guide groove 73, the insertion pin 78 is positioned corresponding to the one insertion hole 101 on the front side of the optical disk drive 98, and the regulating protrusion 77 is elastically moved. After returning, the insertion pin 78 is inserted into the one insertion hole 101. Therefore, the movement of the optical disk drive 98 in the front-rear direction and the left-right direction is restricted.

When the supported pin 100 on the rear side is inserted to the end of the guide groove 73, the supported pin 100 attached to the lower end of the right side surface 98a is simultaneously inserted into the guide groove 74. When the supported pins 100 on the upper end side are inserted into the guide grooves 73 and the supported pins 100 on the lower end side are inserted into the guide grooves 74, the supported pins 100, 10
The shaft portions 100a, 100a, 100a of 0, 100 are inserted into the slits formed by the fall-off preventing pieces 73a, 73b, 74a, respectively, to prevent the optical disk drive 98 from falling off from the guide grooves 73, 74 (see FIG. 35). ). Also, the supported pins 100, 100 are
When inserted to the end of 3, 74, the shaft 100
a, 100a, 100a are fall-off preventing pieces 73a, 73b,
Since the optical disk drive 98 is inserted into the slit formed at 74a in a press-fit manner, the user can easily determine that the optical disk drive 98 has been inserted to an appropriate position.

The connection line may be attached to the optical disk drive 98 in a state where the supported pin 100 is inserted up to the end of the guide groove 73.
It may be performed in a state before 0 is inserted to the last part of the guide groove 73. If the operation is performed before the supported pin 100 is inserted to the end of the guide groove 73, a large working space is provided on the rear side of the optical disk drive 98, so that connection wires can be easily attached.

The optical disk drive 98 includes the supported pin 1
00, 100, 100 outer flange portions 100b, 10
0b and 100b are regulated by the guide grooves 73 and 74, and the movement in the vertical direction is regulated.

As described above, the optical disk drive 98
To the chassis 56 is completed. When the optical disk drive 98 is mounted on the chassis 56, the optical disk drive 98 and the hard disk drive 86 mounted on the chassis 56 are positioned with a slight left and right separation, and the optical disk drive 98 is hidden by the hard disk drive 86. (See FIG. 4).

Conversely, when removing the optical disk drive 98 from the chassis 56, the restricting projection 77 is bent upward and the insertion pin 78 is inserted into the insertion hole 101 of the optical disk drive 98.
From the optical disk drive 98 and the front support 6
This can be done by pulling out the front side from the drive insertion slot 60a of No. 0. Since the holding projection 77a is provided at the tip of the regulating projection 77, when the insertion pin 78 is pulled out, the insertion pin 78 can be removed by grasping the holding projection 77a and bending the regulating projection 77. Removal of the 98 from the chassis 56 can be performed very easily.

As described above, when the optical disk drive 98 is attached to the chassis 56, the optical disk drive 98 is moved forward to insert the supported pins 100, 100, 100 into the guide grooves 73, 74 and to insert the insertion pin 78. Since it suffices to insert into the insertion hole 101, no jig such as a screwdriver is required at all, the mounting work is easy, and the workability can be improved.

In addition, the removal of the optical disk drive 98 from the chassis 56 can be achieved simply by bending the regulating projection 77 to pull out the insertion pin 78 from the insertion hole 101 and pulling the optical disk drive 98 forward from the drive insertion opening 60a. For example, when replacing the optical disk drive 98, the operation can be easily performed in a short time,
Also in this case, the workability can be improved.

Furthermore, since the optical disk drive 98 is directly attached to the chassis 56 without using a bracket holder or the like, the positional accuracy of the optical disk drive 98 with respect to the chassis 56 can be improved.

In addition, the regulating projection 77 provided on the upper surface support 59 of the chassis 56
Is provided as an elastic displacement portion that is elastically deformed by sliding contact with the upper surface 98b of the optical disk drive 98 when the optical disk drive 98 is inserted into the guide groove 73, so that a complicated configuration for attaching the optical disk drive 98 to the chassis 56 is not required. The position of the optical disk drive 98 attached to the chassis 56 can be regulated simply and reliably.

As described above, the distance from the front end of the chassis 56 to the insertion pin 78 and the distance from the front end of the chassis 56 to the drop prevention pieces 73b of the guide groove 73 and the drop prevention piece 74a of the guide groove 74 are equal to each other. Since they are the same, a stable mounting state of the optical disk drive 98 mounted on the chassis 56 can be ensured, and the optical disk drive 98 is less likely to vibrate.

As described above, the optical disk drive 98
When the hard disk drive 86 is attached to the chassis 56, the optical disk drive 98 is located at a position hidden by the hard disk drive 86.
Since the optical disk drive 98 is inserted from the drive insertion opening 60a of the front support 60 and is attached to the chassis 56, it does not interfere with the hard disk drive 86 when the optical disk drive 98 is attached.

Accordingly, the hard disk drive 86 is once removed from the chassis 56 and the optical disk drive 98 is removed.
Need not be mounted on the chassis 56, and the chassis 5 of the hard disk drive 86 and the optical disk drive 98
6 can be separately attached and detached, and the workability can be further improved. Further, since a jig such as a driver is not required for mounting the optical disk drive 98, even if the hard disk drive 86 is already mounted on the chassis 56, the jig such as a driver interferes with the hard disk drive 86 and is mounted. There is no worry that it will cause trouble.

In the above description, the guide groove 7 is formed in the chassis 56.
3 and 74, and the optical disk drive 98 is mounted on the chassis 5
6, the optical disk drive 9 is shown.
