Claims

[Scope of utility model registration request]

A cassette holder for accommodating a tape cassette from above is pivotally supported at both ends of its lower part by a main body support chassis so as to be freely rotatable in the front and back direction, and a switch lever for engaging and disengaging the tape cassette from the upper part is disposed on the main body support chassis. , the main body support chassis and the cassette holder are connected at the sides by a piston damper, a resilient means for biasing the cassette holder in the opening direction is fixed to the main body support chassis side, and the cassette holder is rotatable. In the opening mechanism of the cassette holder, which includes an eject hook attached to the main body support chassis, the springing means is moved in the opening direction only during the initial rotation of the cassette holder immediately after the eject hook releases the cassette holder. a first torsion spring that has a strong elastic force that biases the tape cassette to release the tape cassette from the switch lever; and a first torsion spring that has a weaker elastic force that biases the cassette holder in the opening direction. 1. An opening mechanism for a cassette holder, characterized in that said torsion springs are fixed to the same fulcrum on the side of said main body supporting chassis.
