<p>PURPOSE:To release lock only with no change of a program although a program switch is pushed, by pushing the program switch to actuates plunger and then actuating a lock lever to release the lock. CONSTITUTION:A quick forward lever or a rewind lever is pushed up to make the hook part of a lock lever 13 separate from the pawl of a ratchet 1. Thus a current flows to an energizing coil 12 of a plunger 8 to suck the plunger 8, and the ratchet 1 is kept at rest. A pinch roller 26 or 27 have an alternate contact with a forward rotary shaft 24 or a rewind rotary shaft 25 by pushing the quick forward lever or the rewind lever. Thus a cassette tape is quickly forwarded or rewound to switch the program and to lead out the head of the tape. The power supply current is supplied to the coil 12 by means of a program switch 9 after switching the desired program. Thus the plunger 8 is sucked to reset the quick forward lever or the rewind lever.</p> |
