Claims

[Scope of utility model registration request]

A cassette holder into which a plurality of cassettes of different sizes are selectively inserted, and the cassette holder is reciprocated between a cassette insertion position where the cassettes are inserted and a cassette installation position where the inserted cassettes are installed. a reciprocating drive device, the cassette attachment/detachment device configured to selectively mount and eject the plurality of cassettes from the cassette mounting position by reciprocating and reciprocating the cassette holder; an extrusion mechanism is provided, the cassette extrusion mechanism having a plurality of cassette extrusions selectively engaged with the plurality of cassettes and having mutually different reciprocating strokes; When the cassette is selectively inserted into the cassette holder, it is pressed by the cassette and moved forward to the forward position, and when the cassette holder is moved back from the cassette mounting position to the cassette insertion position, The cassette holder is configured to be forcibly moved back from the forward movement position to the backward movement position, and when the cassette holder moves back, the plurality of cassettes are pushed out by the plurality of cassette pushers with a stroke commensurate with the size of the cassettes. A cassette attachment/detachment device configured to be forcibly pushed out of a holder.
