<p>PURPOSE:To enable to easily find out a favorite tune by making a high speed reproduction state again after a prescribed short time in a reproduction state has elapsed, automatically repeating said operation, and reproducing an identification key in a short time. CONSTITUTION:When the switch 30 is closed instantaneously, an output of the FF27 and that FF28 become H and L, respectively, inputs of the driving parts 23, 25 become H, therefore the motor 15 rotates in the direction as indicated with an arrow, and the plunger becomes an exciting state. Since this state is a queue state, if there is a signal in the tape, it is reproduced. An output of the amplifier 26 becomes H by the head of the next tune through between tunes, the state of the FF28 is inverted, and its output becomes H. By this output H, the FF27 is reset and the output becomes L, therefore the queue state is released, and when an output of the FF28 becomes H, an exciting current flows into the electromagnetic plunger 17 from the driving part 24, and the reproduction state is made.</p> |
