Abstract
PURPOSE: To smoothly reproduce immediately after automatic stop with a simple constitution, by clocking the automatic stop via the memory switch with the circuit having a given time constant.
CONSTITUTION: When the tape running is detected with the rotation detection circuit RS, the transistor T1 is conducted, the integration voltage of time constant circuit consisting of C1 and R1 is fed to the comparator COM, and it is compared with the reference voltage. On the other hand, when the count value of the tape counter is a given number and the switch S2 is open, the integrated voltage is momentarily lowered with the time constant circuit having the same time constant consisting of C2 and R2, the transistor T2 is conducted via the comparator COM, the switch S2 is open via the automatic stop plunger PL and the tape running is stopped. When the switch S2 is open and the mode is of reproducing state immediately after this, even if the switch S1 is kept closed, the integration voltage is not lowered with the parallel time constant circuit having the same time constant and no power interruption is made, allowing smooth reproduction to be restarted.
