<p>PURPOSE:To prevent a cassette from getting over a stopper without providing special members by extending the stopper in the thickness direction of the cassette and tapering the stopper to avoid the operation range of a tape protecting cover of the cassette. CONSTITUTION:A position control part 3a of a cassette 3 inserted to a cassette holder 1 in the direction of an arrow is brought into contact with a stopper 1b and is stopped in a prescribed position. The stopper 1b is extended in the thickness direction of the cassette 3 and is tapered to avoid the operation range of a tape protective cover 3b of the cassette 3. When the cassette 3 whose movement in the thickness direction is controlled by a bend 1d or the like prescribing the operation range of a cassette pressing member 1c tries to get over the stopper 1b, the cassette 3 is smoothly returned to the prescribed position because of the taper of the stopper 1b. Thus, the cassette 3 is prevented from getting over the stopper 1b.</p> |
