PROBLEM TO BE SOLVED: To reliably hold a disk on a disk holder when storing the clamped disk on the disk holder. SOLUTION: When the disk is transported in a storing direction from a clamp location, and even when the disk is not transported to a prescribed position, the central hole of a disk is pressed in the storing direction by turning force from the retreat attitude to the regulation attitude of an arm 16 cooperatively operating when retreating a drive unit 50. An actuation arm 70 to actuate the arm 16 is provided, and a detection switch 74 operated by the turning actuation of the actuation arm 70 is provided. The detection switch 74 is turned on when the arm 16 takes the regulation attitude. COPYRIGHT: (C)2003,JPO
