Claims

[Scope of utility model registration request]

a cassette holder that holds a cassette and reciprocates between an insertion position and a mounting position of the cassette;
a first gear that is rotatably supported on a support shaft and rotates upon being transmitted with the driving force of a drive source; a second gear that is rotatably supported on the first support shaft; In a cassette loading device, the cassette loading device is rotatably supported on a support shaft, has a gear portion that meshes with the second gear, and a rotating arm that engages with the cassette holder and moves the cassette holder. , a torsion spring that passes through the first support shaft and is interposed between the first gear and the second gear, and a torsion spring that extends between the first gear and the second gear; a first locking piece and a second locking piece that are provided at mutually symmetrical positions and capable of locking one end and the other end of the torsion spring, respectively; and mutually symmetrical positions of the opposing surfaces. , and are respectively disposed at positions that do not interfere with the first locking piece and the second locking piece when the first gear and the second gear displace each other's rotational positions. A driving force transmission mechanism comprising a third locking piece and a fourth locking piece capable of locking one end and the other end of the torsion spring, respectively.
