Claims

[Scope of utility model registration request]

It has a cassette holder that can freely move back and forth between a cassette insertion position where a cassette is inserted and a cassette installation position where the inserted cassette is installed, and a worm mechanism having a worm and a worm wheel is interposed and is driven by a motor. In the cassette attachment/detachment device configured to drive the cassette holder in reciprocating motion by a driven gear drive mechanism, at least the worm mechanism and the cassette holder in the gear drive mechanism are slidable in an axial direction within a transmission path or between the worm mechanism and the cassette holder. A cassette attaching/detaching device characterized in that a movable gear is interposed, and the sliding of the gear disconnects the transmission state in the transmission path so that the cassette holder can be manually reciprocated.
