Abstract

PURPOSE:To make a circuit configuration simple and small-sized, by providing a recording signal primary means for changeover-controlling a time constant circuit to repeated charge and discharge in a prescribed level or less, and charge up to a prescribed level, in accordance with whether a recording signal exists or not. CONSTITUTION:A recording signal primary means 11 consisting of transistors Q1-Q5 and a time constant circuit TC is provided, and it is connected to an electronic governor circuit 13 for controlling a tape driving motor M. When there is no signal from a recording amplifier A, the time constant circuit TC is entirely charged, a transistor Q6 is turned off, running of a motor is stopped, and when a signal has been inputted, the time constant circuit TC is made a repeated charge and discharge state of full charge or less, and the motor M is made to run through the transistor Q6. Accordingly, it is possible to make a tape run immediately when a recording signal is inputted, and to stop the tape after a time which is decided by the time constant circuit TC has passed, by stop of the recording signal, and the circuit configuration is simplified.
