<p>PROBLEM TO BE SOLVED: To obtain an apparatus by which a mechanism can be set surely to a stop state by adding a simple circuit by a method wherein a smoothing capacitor, a solenoid, a second capacitor, a second switch, an electricity- reception detection means and a stop-signal generation means are provided. SOLUTION: A cassette mechanism is set to a reproduction operation state, and a cassette tape is run. The supply of a power supply is stopped for some cause when a recording signal which is recorded on the cassette tape is reproduced. Then, a detections signal 3 is output from an electricity-reception means 12. By the detection signal 3, a stop-signal generation means 11 and a timer 9 start to operate. An output signal is output from the stop-signal generation means 11 for 40msec from the generation point of the detection signal 3, and the output signal is output again for 180msec after 60msec. The operation starting time T1 of the timer 9 is set in such a way that it is between the time of a first solenoid driving operation and the time of a second solenoid driving operation, and the operation finish time T2 of the timer 9 is set in such a way that the operation of the timer is finished after the finish of the second solenoid driving operation.</p> |
