のスイッチング回路。At least in a device that processes the signal picked up by a magnetic head in an operating circuit and converts it into an audio signal, and supplies the audio signal to an amplifier to drive a speaker,
The power supply current from the power supply unit is guided to the ground through the operating circuit, and a switching transistor is provided between the power supply unit and the amplifier, and the switching transistor is configured such that the operating circuit interrupts operation and is connected to the power source. A switching circuit for a vertical tape recorder, characterized in that when the flow of power supply current from the power supply section to ground is blocked, the switching circuit turns off and interrupts the supply of power supply current from the power supply section to the amplifier.
