By the way, in the telephone device 1 equipped with the TV intercom 21, when there is a visitor or the like during absence and the call button of the intercom is pressed, this intercom image is stored in the image memory and reproduced after returning home. You can check who visited. However, if the absence is for a long time, there is a problem that the visitor cannot be confirmed at any time during that time. Therefore, in the case of absence for a long time, by registering the telephone number of the destination (stay) in the telephone device 1 in advance, when the doorphone is called, the destination is called and the doorphone image is transmitted. It can be so.

FIG. 1 is a flow chart showing the operation of such a telephone device 1. The operation of the main part of the present invention will be described with reference to this flowchart. When the call button of the TV door phone 21 is pressed, the control unit 11 detects this and causes the speaker SP to ring the door ring tone (step S).
1). Subsequently, the intercom image (image of the visitor) taken by the TV intercom 21 is processed by the image processing unit 22 and displayed on the TV monitor 24 (step S2).
Next, start the intercom incoming call timer (step S
3).

Here, the telephone device 1 has a function of a base station (CS) for the wireless slave device 1, and the control unit 11
In this case, the wireless slave unit 3 (that is, the PS) detects whether or not the wireless slave unit 3 (that is, the PS) is within its own area through the wireless transmission / reception unit 21 and determines (step S4). If the wireless slave device 3 is within range, the intercom image data processed by the image processing unit 22 is transmitted as a wireless signal via the wireless transmitting / receiving unit 12 to the wireless slave device 3.
To display on the display unit 34 of the wireless slave device 3. That is, a user of the telephone device 1 who uses the wireless slave device 3 to make a call via the telephone device 1 carries the wireless slave device 3 and uses the wireless slave device 3.
If the user is in the wireless range (i.e., in the self-employed mode) at that time, if there is an intercom call, the intercom image is sent to the wireless slave device 3 and displayed on the display unit 34. As a result, the user can confirm who has visited from the displayed image, and can immediately return home and respond to the visitor. Further, in this case, as will be described later, the intercom communication can be performed by responding to the incoming call of the intercom on the wireless slave device 3 side.

On the other hand, when the user carrying the wireless slave device 3 is absent for a long period of time, and therefore is not in the range of the telephone device 1, and the absence mode is set in the device 1 (that is, step S6). In the case of "Y"), it is next judged whether or not there is an automatic call (step S7). If the automatic call mode is set, the telephone of the destination where the user stays for a long time is stored in the memory 25 of the device 1. It is determined whether or not the number is registered (step S8). If the telephone number is registered, the control unit 11 sets the telephone number to the line I / F unit 13
To execute the calling protocol by sending
Acquisition and dialing for the SDN line L are performed (steps S9 and S10). As a result, a telephone number registered in advance in the telephone device 1 by the user is transmitted, so that the base provided at the destination of the user through the ISDN line L and a switching network (not shown). The station calls the wireless handset 3 carried by the user. If the automatic transmission mode is not set in the device 1, the intercom image data is stored in the image memory 23 (step S11).

Next, the intercom image is transmitted within the range of the telephone device 1 and the response signal is returned from the wireless handset 3 which is displaying the image, so that the "door incoming response" in step S12 is "Y". Then, the TV intercom 21 and the wireless slave device 3 are wirelessly connected to each other via the call channel of the wireless transmitter / receiver unit 12, whereby the wireless transmitter / receiver unit 12 of the wireless slave device 3 is connected.
An intercom call is made via the telephone (step S13).
Further, when the called mobile station 3 which has received the call responds to the call, a message indicating "response" is received from the ISDN line L side, and the "outside line partner response" of step S14 becomes "Y". , A remote wireless handset 3 that responded
Then, the intercom image data is transmitted via the ISDN line L and displayed on the display unit 34 (step S15). Then, at this time, the control unit 11 controls the connection of the communication path between the TV door phone 21 and the outside line L to make the door phone call by the wireless slave device 3 at the remote place (step S13). In addition,
When the response of the wireless slave device 3 cannot be detected and the above-mentioned intercom incoming call timer times out and becomes "Y" in step S22, door incoming call termination processing such as stop of ringing of the door incoming call tone is performed (step S23).

When the end of the wireless handset 3 is detected during such a doorphone call and the determination in step S16 becomes "Y", the doorphone is opened (step S17) and the doorphone call is transmitted / received by the wireless transmitter / receiver 12 as well. If it is through (in the case of “Y” in step S18), the wireless channel is opened (step S19). If this intercom call is through an outside line (ISDN line) (“Y” in step S20), the outside line is opened by executing a predetermined protocol (step S21).

Next, FIG. 2 is a flow chart showing the operation in the case where the user of this device 1 retrieves the intercom image stored in the telephone device 1 from a moving destination at a remote place and confirms it. That is, when the dial number addressed to the telephone device 1 is transmitted via the base station using the wireless slave device 3, the device 1 receives the IS number.
An incoming call arrives via the DN line L and an outside line ring tone sounds (step S31). Here, it is determined whether or not the answering mode is set in the device 1 (step S32). If the answering mode is set, the answering outside line is automatically answered (step S33), and the answering outside line ( ISDN
The response message recorded in the voice recording / reproducing unit 19 is reproduced and transmitted to the line L) (step S34).

After that, the wireless slave unit 3 through the ISDN line
The presence or absence of the remote control signal from is determined (step S3
5) If the remote control signal is not received, an answering machine process is performed to record a message message via the wireless slave device 3 of the other party (user of the device 1) in the voice recording / playback unit 19 (step S36). Thereafter, the termination of the other party is detected by executing a predetermined protocol, or the BT (busy tone) output by the termination of the other party is detected via the analog control unit 18, and the determination in step S37 is "Y". "
Then, the outside line is opened (step S38).

When a response message is sent from the voice recording / playback unit 19 in response to an outside line automatically, the wireless slave unit 3
When the remote control signal is received from the side and the remote control signal indicates an image data request and the determination in step S39 is "Y", the requested intercom image data stored in the image memory 23 is searched (step S40). The searched image data is transmitted to the wireless slave device 3 (step S41). As a result, this intercom image is displayed on the display unit 34 of the wireless slave device 3, so that the user of the telephone device 1 can confirm from time to time what kind of visitor there is from a remote place during a long stay. You can In addition to such a TV door phone, a monitor camera is connected to the telephone device 1 and the image data of the monitor camera is input via an outside line to determine the current state of the installation location of the device 1. Can be easily identified.

In this way, after the intercom image is displayed on the wireless slave device 3 and the wireless slave device 3 ends the call, step S42
When the "BT detection" of is "Y", the outside line is opened (step S38). In addition, the image data is transmitted to the wireless slave device 3
When the remote control signal from the wireless slave device 3 is received and the determination in step S43 becomes "Y" after the transmission to
Returning to step 39, it is determined again whether this remote control signal is an image data request signal. If it is not the image data request, another remote control process is performed (step S44).

If the answering machine is not set when the outside line is received, the outside line answering operation (step S
45) and termination of the incoming call (step S48), and if an outside line response operation is detected by off-hook or the like, the outside line is captured and a call is made by responding to the incoming line call (step S46). Then, when the termination of the call is detected by the on-hook (“Y” in step S47), the outside line is released (step S38), and the process ends. If the "call termination" in step S48 becomes "Y" due to the call origination of the other party, the ring tone is stopped (step S4).
9) Finish.
