<p>PURPOSE:To prevent the occurrence of an accident before it happens by stopping rotation of a forward/backward rotating driving motor and excitation of a play solenoid with a time lag between them. CONSTITUTION:When a rotation stop signal of a forward/backward rotating driving motor 2 is outputted, excitation of a play solenoid 48 is stopped after a prescribed time to release pressing of pinch rolls 6 and 7 to capstan shafts 4 and 5. That is, since excitation of the play solenoid 48 and rotation of the forward/backward rotating driving motor 2 are stopped with a time lag between them, excitation of the play solenoid 48 is stopped about at the time of the end of rotation of flywheel due to inertia. Consequently, momentary fast forwarding of a reel is eliminated to prevent the occurrence of slack of the tape. Thus, the occurrent of an accident of tape jam or the like is prevented.</p> |
