The disk rotation operation mechanism 100 is locked in a more stable state than when locked upward. Further, since the disk rotation operation mechanism 100 is locked in a state where the optical disk 105 held in the third disk tray 5 is not clamped, for example, the disk rotation operation mechanism 100 may break down with the optical disk stored in the apparatus. Inconvenience is prevented.

The disk player device 1 having the above-described configuration is formed so that its width is substantially the same as the width of an optical disk having a diameter of 12 cm. Then, such a disc player device 1 includes disc trays 3, 4,
5 so that the optical disk does not fly out. Specifically, it is as shown in FIG.

That is, as described above, when the optical disc is placed on the disc trays 4 and 5 and stored in the apparatus, for example, when the apparatus is tilted, the disc trays 4 and 5 are moved from the disc tray 3. Support pins 29 and 30 are provided to prevent detachment. And the third
Support pins 29 and 30 erected on the disc tray 5
Has a height dimension up to the bottom surface of the second disk tray 4 which is the upper stage thereof, and the support pins 29 and 30 erected on the second disk tray 4 have heights up to the first disk tray 3. It has a size.

The support pins 29 and 30 prevent the optical disk from shifting in the vertical direction, particularly in the depth direction of the apparatus main body in which the reproducing unit 10 is formed. Therefore, these support pins 29 and 30 are provided at intervals shorter than the diameter of the optical disc mounted on the second concave fitting portion 8, that is, 8 cm.

As described above, the first disk tray 3
Are not provided with these support pins 29, 30.
However, the projections 17 are located at positions corresponding to the support pins 29 and 30 provided on the disk trays 4 and 5 on the ceiling 172 formed above the first disk tray 3.
The arrangement of the optical disc 3 prevents the optical disc placed on the first disc tray 3 from shifting in the depth direction of the apparatus main body. The projection 173 is formed of an elastic material so as not to damage the optical disk 105 when it comes into contact with the optical disk 105. Also, this convex portion 173

Therefore, the disc player device 1 can regulate the displacement of the optical disc without increasing the size of the entire device. The first to third disk trays 3, 4, and 5 have a width dimension equal to the diameter of the optical disk.
In order to make the length shorter than 2 cm, a cutout recess 24 is formed so that a part of the outer peripheral edge of the optical disk faces outward. Therefore, the first to third disc trays 3, 4, and 5 do not have the cutout recess 24, and the holding state is worse than that of the disc tray that holds the entire outer peripheral edge of the optical disc. However, as described above, the side wall of the second concave portion 170 provided on the side walls 42 and 90, the top plate portion, and the housing 2
The vertical and horizontal deviations are restricted by the convex portions 173 provided on the ceiling portion 172 of the support member 172, and the support pins 29, 30
This prevents the device body from shifting in the depth direction, so that such inconvenience can be avoided.

As shown in FIG. 25, the first to third disk trays 3, 4, and 5 of the disk player device 1 configured as described above are moved inside and outside the device.
For example, the first disk tray 3 is moved to the outside of the apparatus, which is a disk exchangeable position at which an optical disk can be exchanged (the position of the first disk tray 3 in the figure).
When the optical disk is placed on the disk tray 3, the disk tray 3 is drawn into the apparatus and moved to the standby position. That is, the standby position is a position where the optical disk is not played back and is stocked (the position of the third disk tray 5 in the figure). When playing back the optical disk placed on the disk tray 3,
The disc tray 3 is moved from the standby position to a reproduction position in the reproduction unit 10. Then, in the reproducing unit 10,
At a place where the disk rotation operation mechanism 100 is at the height of the disk tray 3, the disk table support member 104 and the clamper support member 106 are in a standby state with being separated from each other.
