オ付テープレコーダ。In a tape recorder with a radio, the tape recorder is comprised of a radio section equipped with an external device connection terminal and a speaker, and a tape recorder section detachably and connectably equipped with a built-in microphone. When installed, the built-in microphone signal or the signal input to the external device connection terminal is guided through the tape recorder contact of the radio/tape mode switching switch to the recording amplifier of the tape recorder section, and these signals are also routed to the radio section. A muting circuit is connected to the line amplifier, and an opening/closing switch is provided which is turned off in conjunction with connecting an external device to the external device connection terminal, and the radio section and the tape recorder are connected to the line amplifier. First and second switching transistors are provided to which a forward bias voltage is applied when the power switch of the section is turned on, and the first switching transistor becomes conductive in connection with the turning off of the opening/closing switch, and the built-in microphone signal is output. A tape recorder with a radio, characterized in that the muting circuit is grounded and the second switching transistor is rendered conductive to render the muting circuit inoperable.
