PURPOSE:To switch the function of exclusive response or of response + recording automatically in response to the content of a response message. CONSTITUTION:In recording a response exclusive message, an oscillator 33 of a control circuit 5 is driven by depressing a switch 31 and the oscillator 33 is oscillated at a frequency f1 for a prescribed time. The control signal of this frequency f1 is recorded on a response message tape 11 at first and the response message is inputted. On the other hand, in recording the response + recording message on the response message tape, a switch 32 is depressed and an oscillator 34 is driven with the control of the control circuit 5. The oscillator 34 generates a control signal in a frequency f2 different from the f1 for a prescribed time, the control signal in the frequency f2 is recorded on the tape 11 and then the required response message is recorded. In case of the response of telephone, the function of the exclusive response and of response + recording is automatically selected depending whether the control signal f1 or f2 is reproduced. |
