るテープレコーダー回路。In a tape recorder that listens to tape playback signals through headphones, a high-potential control voltage is output that sets a muting transistor connected to a tape playback signal path to a conductive state and sets a microphone signal amplification circuit to an operating state. A control circuit is provided, a time constant circuit is connected to the control circuit, and when a normally open mute switch is closed, a high potential control voltage is output from the control circuit, and after the mute switch is opened, the time constant circuit is output. A tape recorder circuit characterized in that it is configured to output the control voltage for a certain period of time.
