Claims

[Scope of Claim for Utility Model Registration] A housing that accommodates an inserted recording medium storage case, and a housing that connects the housing between a case insertion/removal position where the case is inserted or removed and a case attachment position where the case is installed. The housing support mechanism is comprised of a housing support mechanism movably supported in a substantially L-shape, a motor, a worm gear device including a worm rotated by the motor, and a worm gear, and the housing support mechanism is operated by rotation of the worm gear. A recording medium storage case automatic loading/unloading device comprising a drive mechanism for moving the drive mechanism, the drive mechanism being fixed at its base side and arranged in alignment with the motor shaft of the motor, and bearing the worm, and the worm. and a joint member fixed to the motor shaft and connected to the worm with a play over a predetermined angle in the rotational direction. Attachment/detaching device.
