Abstract
In order to prevent drop-out in recording and reproducing, a cassette back lid is constituted by a first swing plate having a first engagement member engageable with a first cam surface, and a second swing plate having a second engagement member engageable with a second cam surface. The first swing plate is urged by torsion springs, in the lid opening direction. Therefore, a rotational operation of a cassette front lid in the lid opening direction causes the first swing plate to swing in the lid opening direction, and the second swing plate to swing in the lid opening direction, independently of the swing motion of the first swing plate, that is, the first and second swing plates swing relative to each other and also relative to the front lid in response to the swinging movements of the front lid between its opened and closed positions. This arrangement makes it possible to add the cassette back lid behind the front lid without changing the conventional open angle, and to improve the ability of protecting the tape.
