PURPOSE:To avoid the unnecessary running of the sound recording tape by giving the up-counting action to the up/down-counter at the time of reproduction and then stopping the reproducing action of the recording tape by the output signals given from the logic circuit when the coincidence is obtained between the up-count value and the counter's value. CONSTITUTION:With arrival of the call signals, automatic telephone answering device's primary part 2 has the closure connection to the telephone circuit and sends the recorded answer message to the caller to then set the answering device under the recording state. When the recording is over for the message sent from the caller, the 1st control signals are counted via up/down-counter 14 and counter 15, and at the same time the down-counting is given to counter 14 via the 2nd control signals recorded at the rewinding time of the tape through the remote hearing operation. Then the up-counting is given to counter 14 at the reproducing time. And when the coincidence is obtained between the value of the up-counting and the value of counter 15, the reproducing action of the recording tape is stopped by the output signals given from the logic circuit. Thus the unnecessary running can be avoided for the recording tape. |
