Claims

[Scope of Claim for Utility Model Registration] A turntable, a disk set part in which a large-diameter disk or a small-diameter disk is set, and a large-diameter or small-diameter disk set in this disk set part directed toward the turntable. a disk moving means for moving the small-diameter disk in the opposite direction, and a disk moving means for moving the small-diameter disk in the opposite direction; a small-diameter disk positioning position for positioning, and a large-diameter disk for positioning the large-diameter disk at a position where its center coincides with the rotation center of the turntable when a large-diameter disk is moved by the disk moving means. A disk positioning member is provided so as to be movable to a disk positioning position. Usually, the disk positioning member is locked at a small diameter disk positioning position, and when a large diameter disk is moved by the disk moving means, this a locking member that releases the lock in conjunction with the movement and allows the disk positioning member to move from the small diameter disk positioning position to the large diameter disk positioning position; and a locking member whose center coincides with the rotation center of the turntable. When a certain large-diameter disk is moved toward the disk set section by the disk moving means, the disk positioning member operates in conjunction with this movement to move the disk positioning member from the large-diameter disk positioning position to the small-diameter disk positioning position. 2. A disk player comprising: a reset member for moving the disk positioning member and for allowing the locking member to move to a lock position in which the disk positioning member is locked at a small diameter disk positioning position.
