[Effect of idea]

As described above, in the present invention, the disk chuck arm, which moves up and down together with the disk transport mechanism, is brought into abutment engagement with the contact portion provided on the main body of the device immediately before the completion of the lowering operation of the disk transport mechanism, and the disk chuck arm is rotated. Since the disk placed on the disk table of the player section is clamped by the disk chuck section provided on the disk chuck arm, an independent drive source is provided to operate the disk chuck section. The mechanism can be simplified without the need for complicated control.

Furthermore, since the disc can be clamped onto the disc table at the same time as being transported to the disc player section, the clamping operation can be performed quickly and the performance can be started quickly.

Furthermore, the disk chuck arm is rotated in conjunction with the lowering movement of the relatively heavy disk transport mechanism, which is provided with a disk storage case and a disk pull-out mechanism for holding the same, thereby clamping the disk to the disk table. Therefore, the load applied to the drive motor of the disk transport mechanism can be reduced, and it is possible to prevent the drive motor from becoming larger due to the disk chuck arm being associated therewith.
