Claims

[Scope of utility model registration request]

An incoming circuit that confirms the reception status, a holding circuit that holds the output of this circuit, a relay and drive motor that are excited and driven by the output, and a line that is connected in parallel to the telephone through the contacts of the relay and -. a transformer, a recording/reproducing amplifier connected to the transformer for reproducing a called party response message from an answer tape and transmitting it to the line or recording a caller's message on a receiving tape; a timer for switching the operation mode of the amplifier and stopping the operation of the holding circuit after a certain period of time;
a timer cut circuit that changes the timer one hour by switching the timer between response, reception mode and response-only mode; a pulse detection circuit that detects a caller's cut midway through; and a pulse delay circuit that delays the detection pulse of the mid-cut by a predetermined time,
An answering machine configured to change one hour of a timer via a timer cut circuit using a delay pulse obtained from this circuit, and to stop the operation and restore the line after a predetermined period of time has elapsed since the detection of the cut. Telephone device.
