Claims

[Claims for Utility Model Registration] ■ In an audio device that amplifies the audio output signal of a sub-device removably attached to the main device by an amplifier circuit of the main device, a common contact is connected to the drive power source in the main device. a main power switch that supplies driving power from the common contact to the amplifier circuit through the on contact when the main power switch is turned on; A switch circuit is provided that supplies the driving power to the amplifier circuit through the common contact and the off contact of the switch, and controls the supply of the driving power depending on the presence or absence of the control signal when the main power switch is turned off. Audio equipment made like this. ■ The main device is formed by a receiver having an amplifier circuit, and the sub device is formed by a tape recorder to which the driving power is supplied, and the sub power source controls supply and cutoff of the driving power to the sub device. A utility model registration claim 1, wherein a switch is provided, and a control signal is output when the sub power switch is turned on, and the control signal is cut off when the power switch is turned off and the sub device is automatically stopped. The audio equipment listed. (2) The audio device according to claim 1, wherein the main device is formed by a receiver having an amplifier circuit, and the sub device is formed by an electronic clock.
