Abstract

PURPOSE: To get rid of a noise which is caused at the time when the pause is released, by stopping the bias oscillation when sound recording has paused.
CONSTITUTION: When the pause switch 2 is closed in a sound recording state that the sound recording switch 3 has been closed, the AND gate 11 is closed, application of a high level output passing through the inverter 9 is stopped, and the transistor 12 turns off. In this way, the head plate goes back through the play-solenoid 15 which is demagnetized, and sound recording pauses. On the other hand, the line voltage is not supplied to the bias oscillation circuit 16 whose transistors 27, 28 have turned off after a regular time according to the discharge time constant of the capacitor 26 by closing the switch 2, and the circuit 16 is stopped when sound recording has paused. In the same way, when the sound recording pause is released and the recording is restarted, the restart of operation of the stopped circuit 16 is decided in accordance with the charge time constant of the capacitor 26, and since generation of a noise at the instant when the sound recording head has been pressed against the tape is prevented, no noise is recorded.
