PURPOSE:To increase the effect on practical usage for an automatic answering telephone with remote monitor, by recoring the total stored time through the integration of time operated from the first and reproducing this at any time. CONSTITUTION:When a response tape T-1 starts running with the incoming call from the 3rd party and a response message and a control signal are reproduced, a reception tape T-2 starts running at recording state and a pulse width switching circuit 16 and a 2-pulse generating circuit 13 are driven. On the other hand, when the control signal is reproduced, power is fed to a stop watch 14, a contact y3-1 is closed with the 2nd pulse of the circuit 13 after 1 second, and the announcement of the watch 14 (after one second) is recorded on the tape T-2. Next, when the reproduction of the control signal is finished, a beat tone oscillation circuit 8 is operated and the message from the caller is recorded on the tape T-2, and when the elapsed time of the watch 14 is temporarily stopped, a voice (e.g. ''one minute and 15 seconds has elapsed'') is recorded with a 4-second timer 10. |
