Claims

[Scope of utility model registration request]

first and second tape recorder mechanisms, a first electronic switch circuit that derives a tape playback signal from one of the first and second tape recorder mechanisms that is in a playback state; a function switch that selectively switches and derives the line input and microphone input, respectively; and when both the first and second tape recorder mechanisms are in a non-operating state, the function switch derives the line input and microphone input. When one of the first and second tape recorder mechanisms is in the playback state and the other is in the recording state, the signal led out by the first electronic switch circuit is sent to the sound reproduction system. a second electronic switch circuit leading to the reproduction system;
A switching circuit for a tape recorder device, comprising: a recording circuit that supplies the signal derived by the second electronic switch circuit to the recording signal input terminal of the tape recorder mechanism set to the recording state.
