特徴とするカセツト着脱装置。 A pair of support plates arranged vertically on the left and right sides of the cassette holder are provided with guide grooves bent at almost right angles, and the cassette holder is guided by the guide grooves to move the cassette holder backward from the cassette insertion position. The cassette holder is configured to be capable of reciprocating along a locus of movement in which the cassette is pulled in horizontally and then lowered vertically to the cassette mounting position, and the cassette is attached to and removed from the cassette mounting position by reciprocating the cassette holder along the locus of movement. At least one cassette ejecting lever is rotatably provided on the rear side of the cassette holder, and a protrusion is provided on the inside of the at least one support plate on the horizontal path of the movement locus, so that the cassette ejection lever is inserted into the cassette holder. The cassette is used to push one end of the cassette eject lever to move the cassette eject lever from a backward position at the front side of the cassette holder to a forward position at the rear end of the cassette holder, and the cassette holder is moved from the cassette mounting position. When moving the cassette back to the insertion position, the other end of the cassette ejecting lever is brought into contact with the protrusion when the cassette ejecting lever passes along the horizontal path of the movement locus, and the cassette ejecting lever is moved from the forward movement position to the return movement position. In the cassette attachment/detachment device, the cassette ejection lever is rotated to push the cassette in the cassette holder with one end of the cassette ejection lever, and as the cassette holder moves back to the cassette insertion position, the cassette is pushed out of the cassette holder. , restricting one end of the cassette ejecting lever, which has been rotated from the backward movement position to the forward movement position by the cassette inserted into the cassette holder, from being rotated any further toward the rear side of the cassette holder. a first stopper is provided on the cassette holder;
The protrusion is configured as a rotary lever rotatably attached to the support plate, and the rotary lever is rotatable in forward and backward directions on the horizontal path of the movement locus of the cassette holder. and a rotation biasing spring that biases the rotation lever in the backward movement direction of the cassette holder so that the tip of the rotation lever protrudes inside the support plate, and rotation by the spring. a second stopper for limiting the amount of rotation of the movable lever in the backward movement direction;
When the cassette holder is moved forward from the cassette insertion position to the cassette mounting position and the other end of the cassette ejecting lever comes into contact with and passes the tip of the rotating lever, the first stopper rotates the cassette holder. While the cassette ejecting lever is held in the forward movement position by motion restriction, the rotating lever side is rotated in the forward movement direction of the cassette holder against the spring to release the cassette holder. A cassette attachment/detachment device characterized by:
