<p>PURPOSE:To make easy the timing adjustment of both playback systems and to simplify the constitution of a compensator, by adjusting signal timing of a compensation reference signal system at normal reproduction and a brake pulse generating system at slow still reproduction with one variable resistor. CONSTITUTION:To a remote control connector 50, a compensation reference signal processing system A at normal reproduction having the 1st time constant circuit 31 and a brake pulse generating system B having the 2nd time constant circuit 41 are connected and a remote control circuit 51 is connected to the connector 50. A variable resistor 32 is connected to the input side of the circuit 31 to enable to adjust the signal timing of the signal processing system A and the generating system B. At normal reproduction, a reference signal obtaining discharge or charge of the circuit 31 is taken as the reference frequency, and the output of the signal processing system A is applied to a phase detector 21 controlling the revolution of a capstan motor 11 and a brake pulse in phase adjustment at the circuit 41 is inputted to a brake circuit of the motor 11 at slow still reproduction.</p> |
