<p>PURPOSE:To let a cassette be automatically set in a performance state by providing a head mounting plate stopper which detects that the cassette has moved perpendicularly. CONSTITUTION:Arrangement is so made that, as the cassette is inserted, primary unlocking of a head mounting plate 54 (unlocking of a stopper 64) is accomplished and as the cassette 2 is set in the performance state, the head mounting plate 54 is moved, whereby moving timing of a head 55 and pinch roller 62 may be surely performed.</p> |
