PROBLEM TO BE SOLVED: To prevent drop of a disk in an oblique state by surely releasing the disk.SOLUTION: First to third holding levers 61 to 63 are attached to a disk holding arm 40. An insertion part 75 inserted into a disk hole Dh of a disk D is formed at each of the holding levers 61, 62. In a leading end of the insertion part 75, a hook part 76 is formed which abuts on the lower surface of an edge of the disk hole Dh and holds the disk D. An insertion part 79 is formed in the third holding lever 63, but the hook part 76 is not formed. Each of the holding levers 61 to 63 is rotated between a holding position at which the disk D is held and a releasing position at which holding is released. In a disk presser 90 holding the disk D between the hook part 76 and the disk presser 90, a stopper 93 is provided which abuts on the wall surface Df of the disk hole Dh when the holding levers 61 to 63 are each rotated from the holding position to the releasing position and which separates the disk D from the hook part 76. |
