Claims

[Scope of utility model registration request]

The recording and playback circuit has a stereo configuration, and includes one speaker that is driven when no plug is inserted, a jack that supplies a stereo signal to the outside when the plug is inserted, and an output current limiter that attenuates the stereo output current, and the above-mentioned When the plug is not inserted into the jack, the speaker is driven by a monaural signal obtained by mixing the stereo signal, and when the plug is inserted into the jack, the speaker is disconnected, and the stereo signal is driven by the output current. A tape recorder configured so that a stereo signal is attenuated by a limiter and supplied externally from a plug.
