At this time, even when the caller does not transmit a message, the second memory circuit (20) is in a state where the memory is full, and when the next call arrives with a calling signal from the caller and a response message is transmitted, the third memory circuit (21) is activated. The message from the caller will be stored, and the second memory circuit (20) will not store anything at all, and the few memory circuits will not be available, meaning that almost no response message will be stored.

According to the present invention, after the reading of the response message is completed and the receiving message from the caller is stored, the caller can receive the message within the time that can be stored in the second memory circuit (20). A voice detection circuit (15) detects the presence or absence of a telephone number sent from the telephone number. If the received message cannot be detected within the above-mentioned time period, the control circuit (9) is controlled, and the second memory circuit (20) is stored in the storage state at that time.
A signal is applied to the erase terminal (20d) of the second memory circuit (20) to erase the memory of the second memory circuit (20). Then, the second memory circuit 20) will be in a state where it has not been stored, so the next time the response message is transmitted, the second memory circuit 20) will be in a state where it is not stored.
) is placed in a state where the message received from the caller is stored, and the message received from the caller is stored in each memory circuit without waste.

An automatic response switch (5) is used to read out the received messages stored in the first, second and third memory circuits (19), (20) and (21) while the owner returns home and is away.
and turn on the playback switch (7). Thereby, the second audio conversion circuit (23) is operated by the control circuit (9), and the switch circuit (24) is switched to the output terminal (24a) side. Further, the operating signal from the control circuit (9) is first applied to the selection terminal (19e) of the first memory circuit (19), and the first, second and third memory circuits (19) (20) (21) control terminal (19c) (2
0c) (21c) Since the number readout signal is supplied, first the digital signal of the reception main signal stored in the first memo 1 NO circuit (19) is sent to the readout terminal (19).
