Claims

[Scope of utility model registration request]

A tape recorder equipped with a headphone jack having a signal terminal to which an output signal from an amplifier circuit is applied via an output capacitor, a signal terminal to which a DC voltage is applied for recording operation, and a ground terminal to be grounded; The plug has a plug formed with first and second terminals inserted into the jack and connected to the signal terminal and the ground terminal, and a speaker and a resistor connected in series between the first terminal and the second terminal. a headphone device having a headphone device; a switch that is incorporated in the headphone device and is in a state of shorting both ends of the resistor, and is switched during muting and pause operations to release the short circuit of the resistor;
A signal is provided in the tape recorder and includes a detection circuit that detects a voltage change at the signal terminal and stops the electric motor, and is emitted from a speaker by switching the switch when the tape recorder is in a playback operation state. Muting for a tape recorder, characterized in that the level of the tape recorder is attenuated and the rotation of the electric motor is stopped by detecting a voltage change at the signal terminal due to switching of the switch when in a recording operation state. Cum suspension device.
