When a disk tray stops beyond or before a predetermined rotational position, there has heretofore been a likelihood of the disk tray being unable to be inhibited its rotation. As an arm portion 261b is displaced counterclockwise, a shaft portion 262b of a rotary stopper 262 moves toward an engaging groove 223, so that a sharp portion 262a1 is inserted into the engaging groove 223. At this time, slant faces formed on both sides of the tip of the sharp portion are guided along slant faces of the engaging groove 223 and are inserted to an inner part of the engaging groove. Thus, even when a rotary tray 220 stops at a position deviated from the predetermined rotational position, it is possible to surely inhibit the rotation of the rotary tray 220.
