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 respective holding levers 61, 62. A hook part 76 holding the disk D is formed at a tip of the insertion part 75 abutting on the lower surface of an edge of the disk hold Dh. An insertion part 79 is formed at a third holding lever 63, but the hook part 76 is not formed. The respective holding levers 61 to 63 are rotated between a holding position at which the disk D is held and a releasing position at which holding is released. A stopper 93 abutting on the wall surface Df of the disk hole Dh when the respective holding levers 61 to 63 are rotated from the holding position to the releasing position and separating the disk D from the hook part 76 is provided at a disk presser 90 holding the disk D between the hook part and the holding lever.
