<p>PURPOSE:To smoothly fix a cassette to the prescribed position of a cassette holder by using the member rotating integrally with the gear which is engaged with the gear rotating according to the movement of a cassette holder and pressing from the back face the cassette of under moving to a loading completion position. CONSTITUTION:A pressing member 7a is located at the position obstructing no insertion of a cassette in case of inserting the cassette 1. This can be realized by adequately setting the phase that a semi-circular gear 6 and gear 5 are meshed therewith. When a cassette holder starts to move, the gear 5 is rotated in a clockwise direction and the semicircular gear 6 and lever 7 are rotated in a counterclockwise direction accordingly. The cassette 1 is meanwhile going to move to the rear part [arrow mark (b) direction] but the pressing member 7a presses the back face of the cassette 1, so the cassette 1 is surely fixed to the prescribed position inside the cassette holder.</p> |
