Abstract

PROBLEM TO BE SOLVED: To attain an emergent notice with economical and a simple mount by using a public telephone line for purposes of home medical treatment, aged person care and home security or the like. SOLUTION: A voice signal received through a microphone is stored in a memory 10 in the case of call transmission via a recording and reproducing circuit 11 and an A/D converter circuit 13. Simultaneously a CPU 9 extracts a connection destination telephone number stored in advance from the memory 10 and sends the number to a dial circuit 3, in which the number is digitized and the digitized voice signal and the digitized recording part time in pairs are used to start automatic dialing. In the case of call reception, when a call reception detection circuit 1 detects a call tone from a telephone line 19, the CPU 9 replies it automatically and uses a voice synthesizer D/A converter circuit to send a voice message urging the transmission of the ID number to a caller. Only when the ID number sent by the caller is coincident with a preset ID number, a reception circuit, a speaker and a microphone are coupled via the recording/reproducing circuit 11 to attain a speech enable state.

Use when you want to detect the sound of. The switch (SW2) is mounted close to the microphone,
The caller turns ON each time a call is made and speaks, which has the effect of preventing sending in response to unnecessary sound. The voice input through the microphone is stored in the memory 10 by passing through the A / D conversion circuit 13 from the recording / playback circuit 11. At the same time, the CPU 9 takes out the connection destination telephone numbers □□□... □ stored in advance from the memory 10 and digitizes them by sending the numbers to the dial circuit 3. The CPU 9 activates automatic dialing by pairing the digitized voice with the recording start time. After the automatic dialing, when the response detection circuit 2 detects a response by reversing the polarity of the telephone line, the CPU 9 starts transferring a voice message.

[0010] As shown in FIG. 2, the message includes a calling telephone number, a reproduced voice, and a recording time. Also, as shown in FIG. 2, the outgoing voice is recorded, and by the time the transfer is completed, the fact that the message is being transferred is displayed by flashing LAMP, so that the caller can tell whether the other party is busy or not. In the case of a response, it is possible to know that the transfer has not been completed, and it is possible to confirm the completion of the transfer by ending the blinking. If the next call is made while one message remains stored, the next voice will be stored with the new recording time and the call will be forwarded continuously when the other party answers because the connected phone does not answer Is done. If the connection destination number is a pager, a message such as an outgoing telephone number is transmitted by a signal (for example, a PB signal) from a pager message reception station if the fact is designated at the time of presetting. In this case, the call is made when a call back is received from the pager recipient.

Next, the operation at the time of an incoming call will be described. When an incoming call is received, when the incoming call detection circuit 1 detects a ringing tone transmitted from the telephone line 19, the CPU 9 automatically responds, and the voice synthesis D / A conversion circuit 13 sends a voice message prompting transmission of the ID number to the calling side. I do.
