PROBLEM TO BE SOLVED: To enable a pressing operation of a gear switching mechanism at the time of finishing of centering in disks having different diameters. SOLUTION: This device has a disk centering member 81 which has a disk abutting part 82 and an operating part 83 and in which these are made rotatably by a shaft 84, when a transported disk is abutted to the disk abutting part 82 and pressed, after the disk is rotated centering the shaft 84, rotation is stopped by a stopper 85, and centering is performed, and the gear changeover mechanism 81 press-operated by the operating part 83. The disk abutting part 82 is constituted of a first disk abutting part 82A for rotating the disk centering member 81 to a centering position by the prescribed quantity when a first disk 6 is transported, and a second disk abutting part 82B for rotating the disk centering member 81 by almost same quantity as that of the first disk abutting part 82A when a second disk 7 of which the diameter is different from that of the first disk is transported.
