Since the disk support member is guided by an inclined surface provided on the member and moved in and out, the disk can be moved up and down only when it is pulled into the outer casing, ensuring reliable loading and unloading from the disk table. Furthermore, it is possible to reliably prevent the disk from being moved up and down erroneously during transportation, thereby ensuring the protection of the disk.

Further, since the disk support member can be moved up and down only by moving the slider member, the mechanism is also simplified.
