Is connected to the mobile phone connection circuit 23 by a terminal mechanism or a holding mechanism, even if it is used as a charging device within the communication range in a dwelling unit separately from the base terminal 2. , And may be separated from the master terminal 2.

(Embodiment 2) FIG. 4 is a block diagram showing a configuration of an intercom apparatus with a transfer function according to Embodiment 2 of the present invention. In FIG. Will be explained.

In this device, a recording memory 33 is newly connected to the main control device 21 of the master terminal 2 in the configuration of the first embodiment. This recording memory 33 records the contents of a call and the time of a call.

Further, the communication terminal 8 records a communication device 81 for receiving and transmitting to the outside and transmitting to the outside, operation buttons 82 for setting communication settings and speed dials, and abbreviated dials and call records. And a memory 83 for performing the operation.

According to this configuration, as described in the first embodiment, if there is a call signal from handset terminal 1, a call between base unit terminal 2, mobile phone 4 or communication terminal 8 and handset terminal 1 is made. Starts the call. At this time, in the base unit terminal 2, the contents of the call can be recorded together with the time by the recording memory 33. The start and stop of the recording can be performed by the dial button 25 of the parent terminal 2 or the mobile phone 4.

The contents of the call and the call time recorded in the recording memory 33 are stored in the dial button 25 of the base unit terminal 2.
Alternatively, it can be reproduced or deleted by the mobile phone 4. In particular, such a recording function is advantageous in that the contents transferred to the communication terminal 8 can be confirmed by the base unit terminal 2 or the mobile phone 4.

As described above, in the present embodiment, the slave terminal 1
Can be recorded in the recording memory 33 of the base unit terminal 2 and reproduced, and by recording the time of the call, the visit record of the visitor can be left.

In the present embodiment, a case has been described where the external communication terminal 8 is called from the master terminal 2, but the external communication terminal 8 is recorded in the recording memory 33 of the master terminal 2 according to an instruction from the external communication terminal 8. It is also possible to reproduce the content and time of the call between the slave terminal 1 and the communication terminal 8 which are in operation.

For example, to call the recording memory 33 of the master terminal 2 from the communication terminal 8, call the intercom device with the transfer function from the communication terminal 8, and after starting a call, operate the operation button 82 to record the recording in the recording memory 33. Play it. Also, when it is desired to stop the reproduction of the recording memory 33, the operation button 82 is used.

(Embodiment 3) FIG. 5 is a block diagram showing a configuration of an intercom apparatus with a transfer function according to Embodiment 3 of the present invention. In FIG. Will be explained.

In this apparatus, the mobile phone 5 with a camera is connected to the mobile phone connection circuit 23 in place of the mobile phone 4 in the configuration of the first embodiment, and the security control circuit 34 is connected to the main control device 21 of the master terminal 2. Except that a security sensor 6 such as a security switch and a gas leak detector and a security switch 7 such as a toilet call and a bus call are connected to the security connection circuit 34. It has the same configuration as.

Next, the operation of the present embodiment will be described with reference to the processing flowchart shown in FIG. The operation when a call is made from the slave terminal 1 is the same as the operation shown in the above-described processing flow chart, and therefore will be omitted. Here, the operation when the security sensor 6 is operated or the security switch 7 is operated will be described. explain.

First, when the main control circuit 21 detects that the security connection circuit 34 has received a security signal from the security sensor 6 or the security switch 7 (step S31), the main control circuit 21 issues an alarm such as sounding an alarm from the alarm 27. Is performed (step S32).

Next, the main control circuit 21 detects whether or not the camera-equipped mobile phone 5 is connected to the mobile-phone connection circuit 23 (step S33). The video signal is captured, and the image is displayed on the monitor television 31 (step S34).

Next, the main control circuit 21 needs to forcibly notify the pre-registered destination communication terminal of an alarm at the time of security occurrence.
9 is read out (step S35), and the automatic calling circuit 28 is controlled to transfer the telephone number via the camera-equipped mobile phone 5 connected to the mobile phone connection circuit 23. Is called (step S36).

When the main control circuit 21 receives a response from the destination communication terminal via the camera-equipped mobile phone 5 (step S37), the main control circuit 21 transmits a security alert signal to the other party's communication terminal, and at the same time, attaches the camera. The video signal captured by the mobile phone 5 is transmitted (step S38).

Next, when the communication terminal of the other party disconnects, the main control circuit 21 ends the transmission of the alarm sound and the video signal (step S39), and disconnects the connection with the communication terminal of the other party (step S39). S40), the process ends.

If there is no response from the communication terminal for a certain period of time in step S37 (step S41), the alarm notification is stopped by operating a predetermined button (step S42).
To S43), and the process ends. Note that also in step S33, when it is detected that the camera-equipped mobile phone 5 is not connected to the mobile phone connection circuit 23, the alarm notification is stopped by the alarm stop operation (steps S42 to S43), and the process ends.

As described above, in the present embodiment, when the security sensor 6 such as a security switch or a gas leak detector is activated, or when the security switch 7 such as a toilet call or a bus call is pressed, the transfer setting button is pressed. Regardless of the setting state of 26, an alarm is issued via the camera-equipped mobile phone 5 to an external communication terminal forcibly registered in advance, and a video signal captured by the camera-equipped mobile phone 5 is transmitted. Further, since an alarm is issued via the camera-equipped mobile phone 5, it is suitable for additional installation as, for example, an emergency call device for the elderly living in a room where no telephone line is connected.
