Claims

[Scope of Claim for Utility Model Registration] (1) A cassette holder that accommodates a tape cassette from above, a main body support chassis that pivotally supports the cassette holder at both ends of the lower part thereof so as to be rotatable in the front and back direction, and the upper part of the main body support chassis. a switch lever disposed on the tape cassette for engaging and disengaging the tape cassette from above;
a piston damper that connects the main body support chassis and the cassette holder at their sides; and a piston damper that is fixed to the main body support chassis side and has an active end connected to the cassette holder and elastically biases the cassette holder in the opening direction. In a cassette holder opening mechanism comprising a torsion spring and an eject hook attached to the main body supporting chassis side for engaging and disengaging the cassette holder, the tip of the cassette holder opens on the main body supporting chassis side until the inner surface of the cassette holder reaches an initial open rotation position. 1. An opening mechanism for a cassette holder, characterized in that an elastic contact means is provided for resiliently pressing the tape cassette, and the elastic contact means releases the locking of the tape cassette by the switch lever. (2) The cassette holder opening mechanism according to claim 1, wherein the elastic contact means is constituted by a coil spring. (3) The cassette holder opening mechanism according to claim 1, wherein the elastic contact means is constituted by a torsion spring. (4) The cassette holder opening mechanism according to claim 1, wherein the elastic contact means is constituted by a plate spring. (5) The cassette holder opening mechanism according to claim 1, wherein the elastic contact means is constituted by a U-shaped leaf spring.
