ABSTRACT:
A disk recording-reproducing device including a clamp mechanism and eject mechanism for a disk, which is characterized by an eject board abutable on an insertion front end of the disk and urged toward an insertion opening for the disk, a lock mechanism for locking the eject board when the disk is inserted up to a drive position, a lock-release member for releasing the locked state of the eject board, and a cam member rotatable as it is rubbed by the lock-release member at the time of insertion of the disk. Either the cam member or the lock-release member is movable in cooperation with the eject board to shift in the direction of insertion and ejection of the disk, and the other is movable in cooperation with the clamp mechanism to shift substantially perpendicularly to the revolution plane of the cam member, whereby a comparatively large dimensional clearance is allowed for the cam member and lock-release member.
