Abstract
A magnetic tape apparatus having a magnetic head, reel drive spindles for driving the reels of a magnetic tape cassette and a pressure roller-capstan combination for driving the tape within the cassette. The apparatus includes an actuating member with urging projections for sliding a slidable cover on a magnetic tape cassette of a first type, having a first thickness between its main walls, when the cassette is inserted into the apparatus. A sensor on the actuating means senses the insertion of a cassette of a second type, having a thickness between its main walls greater than the thickness of the first type of cassette, for moving the actuating member to a position which permits the second type of cassette to be fully inserted in the apparatus and cooperate with the reel drive spindles, the pressure-roller-capstan arrangement and the magnetic head.
