Claims

[Scope of utility model registration request]

A pulse generation circuit generates pulses corresponding to the rotation of a reel shaft that runs a recording tape that records messages sent from a caller via a telephone line, and a pulse generation circuit that records messages sent from a caller via a telephone line. a first timer circuit that starts at the same time as the business message is recorded and outputs an output signal at fixed time intervals while the business message is being recorded; A first count circuit that starts counting the number of pulses, resets and starts counting again when the output signal of the first timer circuit is applied, and a count number that the first count circuit was counting before being reset. A count memory circuit that sequentially rewrites and memorizes the count number, and a count number memory circuit that is activated when the message from the calling party is no longer sent, and outputs when a specific time that is slightly longer than the predetermined time determined by the first timer circuit has elapsed. a second timer circuit that outputs a signal; a running state switching means that switches the business recording tape from a recording state to a rewinding state when the output signal of the second timer circuit is output; and an output signal of the second timer circuit; The count number stored in the count number memory circuit is read by receiving the pulse number, and the pulse generated by the pulse generation circuit in response to the rewinding operation of the business recording tape switched by the running state switching means. 1. An answering machine comprising: a second counting circuit that counts down.
