Claims

[Scope of utility model registration request]

A mechanism control circuit for switching operation modes such as recording, playback, and stop, a signal detection circuit to which a monitor signal output during recording or a playback signal output during playback of another cassette tape recorder is applied, and this signal switch means for selectively supplying the output of the detection circuit to the recording terminal or playback terminal of the mechanism control circuit, while a monitor signal or playback signal output from another cassette tape recorder is applied to the signal detection circuit; 1. A cassette tape recorder characterized in that the cassette tape recorder is configured to be in a non-operating state and to start recording or reproducing operation when the monitor signal or reproduction signal disappears.
