PURPOSE:To avoid the unclearness of the beginning of message delivered, by connecting the response tape to telephone line through the operation of the tape switch when callout signal is incoming, and stopping the tape run for a given time. CONSTITUTION:When the callout signal is incoming from telephone linen, the tape switch is operated to deliver the message recorded on the reponse tape and the message for the caller is recorded on the recording tape. In this case, if the caller uses a public phone, the pay tone signal is caused when the line is connected to make unclear the beginning of message. Thus, to avoid it, the unit is provided with the pay tone payse circuit 67 interlocking with the tape switch 21, motor control circuits 30,38, and relay circuit 16, and the tape 20 is stopped for a given time after the response tape 20 is connected to the line. Thus, after waiting the pay tone signal is disappeared, the tape 20 is run. |
