The message recorded on 1 is played back, and the audio signal of the message is sent to the office line through the amplifier 17 and the office line circuit 11. The emergency contact will now know where the call is coming from.

When the message exit is completed, the process proceeds from step 160 to step 170, where cputo activates the hands-free call circuit 28. As a result, the voice from the other party's telephone is outputted from the speaker 5 via the amplifier, and the user's voice is input from the microphone, amplified by the amplifier, and sent to the central office line through the central office line circuit 11. Therefore, the user, such as a bedridden elderly person, can freely talk to an emergency contact number while remaining in the same state.

Then, when the conversation is over and the receiver of the other party's telephone is hooked on, a hook-on signal arrives and this signal is detected by the instantaneous interruption detection circuit 13, the process proceeds from step 180 to step 195, and the CPU 1O operates the central office line circuit 11. On the other hand, if the hook-on signal is not input even after the conversation ends, and for example, silence continues for 20 seconds, the silence detection circuit 16 detects this, and at this time, the CP
olo proceeds from step 190 to step 195, operates the office line circuit 11, releases the office line, and ends the call.

In addition, the fire sensor 26 and gas leak sensor 27 are activated,
When the detection signal is sent to CPU10, the operations from step 120 onward are performed in the same manner as described above, and emergency contacts are notified of fire, gas leak, etc.

On the other hand, when a call is made from an external telephone, the call receiving operation is performed as shown in the flowchart of FIG.

That is, when a bell call is received at the central office line terminal, the bell receiving circuit 12
receives this, CPU10 proceeds from step 200 to step 210, operates the office line circuit 11, and connects the office line to r.
Let it be AM. Next, in step 230, the identification code is read from the memory 24, and this identification signal is sent from the office line circuit 11 to the office line.

When the sending of the message is completed, the process proceeds from step 250 to step 260, where CPU10 activates the hands-free communication circuit 28. As a result, the voice from the other party's telephone is outputted from the speaker 5 through the amplifier of the hands-free communication circuit 28, and the user's voice is input manually from the microphone, amplified by the amplifier there, and sent to the central office line through the central office line circuit 11. Ru. Therefore, the user, such as a bedridden elderly person, can freely talk to the person on the other end of the phone without changing his/her condition.

Then, when the conversation is over and the other party's telephone receiver is hooked on, a hook-on signal arrives and this signal is detected by the instantaneous interruption detection circuit 13, the process advances from step 270 to step 290, and the CPU 10 operates the central office line circuit 11. On the other hand, if the hook-on signal is not input even after the conversation is over, and there is silence for 20 seconds, for example, the silence detection circuit 16 detects this, and at this time, the CP
U10 proceeds from step 280 to step 290, operates the office line circuit 11, and automatically opens the office line.

In this way, when a call is made by operating the call switch 1, or when a call is received from outside, after a message is sent, hands-free calling is automatically enabled, allowing people such as bedridden elderly people and people with physical disabilities to make calls. However, in case of an emergency, you can freely communicate and talk over the phone.

<Effects of the Invention> As explained above, according to the telephone device of the present invention, after the message, etc. sending means sends a message, etc. at the time of making a call or receiving a call, the hands-free calling means is activated, and the hands-free calling means is activated.
