【Example】

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the incoming call control device for a key telephone device according to the present invention will be described below with reference to the drawings. In FIG. 1, 1. ~1n are extension telephones, 2
indicates the main device, and 3 indicates the telephone line. In the illustrated example, there is one telephone line, but it goes without saying that a plurality of telephone lines can be accommodated. Each extension telephone 11 to In is, for example, a button telephone as shown in FIG.
, function keys 14 such as one-touch keys, and a speaker 15 as usual, and a liquid crystal display panel 11 as a display device. Further, in the main device 2, 21 is an exchange switch section, 22 is a central office line trunk for accommodating the telephone line 3, and 251 to 2
5n is an extension circuit. Further, 23 is a PB receiver as a code reception trunk that receives and decodes an identification code from a caller, and 24 is a voice synthesis trunk that outputs a voice message. Further, 26 is a control circuit for controlling each of the above-mentioned circuits, and this control circuit 26 is constituted by a microcomputer. A data table 27 and a character generator 28 are connected to this control circuit 26. In this case, the data table 27 is constructed on the memory, and includes, for example, as shown in FIG. 3, the identification code ID assigned to each called party, the data (code) USR of the called party's name, This is a comparison table with a flag FLG indicating the presence or absence of the called party. The flag FLG corresponds to the identification code, and is set to, for example, "1" when the called party corresponding to the identification code cannot answer the call, and is reset to "0" when the called party can answer the call. That is,
For example, when the called party inputs his/her identification code ID using the dial key 13 of the telephone 1 and then presses the # key and the "1° key," the flag FLG is set to "12" and the callee is registered as absent. The character generator 28 generates display data (
font data). Next, the operation when a call is received from an outside line will be explained. When an incoming call is received from the telephone line 3, in the main device 2, the ring tone signal is detected by the office line trunk 22, and the office line trunk 22 notifies the control circuit 26 of the incoming call. Then, the control circuit 26 controls the exchange switch section 21,
Telephone line 3 is connected to speech synthesis trunk 24 and PB receiver 2
Connect to 3. Then, an audio signal indicating that the identification code ID can be sent, for example, an audio signal saying "Please enter the identification code of the person you wish to speak with" is output from the speech synthesis trunk 24, and this audio signal is sent to the telephone line 3. Sent out. Therefore, if the caller wants to make a call with the identification code ID of the person he/she wants to talk to according to this voice message, for example, "Picture Book" in Figure 2, the caller should enter the identification code ID "12". Enter by pressing the key on your phone, and then press the * key, for example. Then, this identification code ID is sent from the caller's telephone through the line 3, so the main device 2 receives it with its PB receiver 23 and decodes the identification code ID. Then, this decoded identification code ID is PB
The signal is sent from the receiver 23 to the control circuit 26. Then, in the control circuit 26, the flag FLG in the data table 27 is checked using the sent identification code ID as a keyword.
If so, the corresponding person is able to answer the phone, so the sent identification code ID is converted into name data USH of the called party (the corresponding person) based on the data table 27, and further, the character generator 28 The data USR is converted into display data (font data). For example, if the sent identification code ID is "12", it will be converted to the data USR of "Picture Book" and then "
The data is converted into display data for a picture book. Then, this display data and a signal indicating the arrival of a call are sent from the control circuit 26 to all extension telephones 1 through each extension circuit 25. ~1n. Then, all extension telephones 1. ~1n, the display data sent from the control circuit 26 causes the liquid crystal display panel 11 to display the name of the called party, for example the name "Picture Book," and a ring tone is emitted from the speaker 15 as in the conventional case. , an incoming call is displayed on the LED corresponding to the line identification button. Then, the corresponding called party, in this case Mr. Ehon, looks at his name on the liquid crystal display panel 11 and selects extension telephone number 1. When the handset 12 is picked up from one of the extension telephones .about.1n, a communication path is established between the telephone line and the extension telephone that answered the call, and an incoming call can be answered. As described above, even if someone does not answer, the person receiving the call is displayed on the liquid crystal display panel 11, so that the caller can directly connect the incoming call to the desired person. Furthermore, when someone else sees the name on the LCD panel 11 earlier than the person receiving the call, the person receiving the call can be prompted to receive the call even if the person does not respond.
There is no need to answer the line once and then put it on hold, allowing for a quick response. Then, when the main device 2 receives the code from the caller and checks the flag FLG in the data table 27, if the flag FLG-"1°, this means that the called party will answer the call due to absence etc. In this case, the voice synthesis trunk 24 is controlled by the control circuit 26, and a voice signal indicating that the person in question is absent is output from the voice synthesis trunk 24, and is transmitted via the telephone line 3. Otherwise, a busy tone signal is sent to the caller through the telephone line 3. Therefore, even if someone does not answer the call, the caller is informed that the called party is unavailable. In addition, even if a request is made to send the identification code ID when receiving a call, the caller can send the identification code ID of the called party within a certain period of time.
If you do not enter , for example, if the caller does not know the callee's identification code ID, or if the caller is calling from a standard telephone with a dial ring, all telephone extensions will be 11 to 1n, only the incoming tone and LED display are performed. In this case, characters identifying the called party are not displayed on the liquid crystal display panel 11 of each extension telephone, but a message such as "Someone please answer" may be displayed. Although the above description deals with the case of an incoming call from an outside line, the name of the incoming caller can be displayed in the same way when an extension call is made between extension telephones. Furthermore, the extension telephone is not limited to the case where it is connected via a wire as in the above example, but is also applicable to the case where a cordless telephone handset is used. [Effects of the Invention] According to the present invention, when an incoming call is received, when an identification code is sent from the caller, the name of the called party is displayed on the display device of each extension telephone based on the sent identification code. Since it is displayed, the corresponding recipient can respond immediately. Therefore, there is no need for the conventional troublesome operations of having another person answer the call, hold it, and then transfer the call, which reduces the time it takes for the person receiving the call to actually answer the call. You can make calls. Furthermore, there is no need to appoint a specific person to handle the telephone calls. Furthermore, if the person receiving the call does not notice the incoming call and does not answer the call easily, the person receiving the call can see the display corresponding to the recipient on the display and notify the recipient and prompt the person to respond. can do. In addition, if the called party corresponding to the identification code sent from the caller is absent or does not wish to answer the phone, the main device will automatically make the call by registering the caller's absence in the data table. Since the caller is informed of the caller's absence, there is no need for someone to answer the incoming call and verbally inform the caller of the caller's absence, unlike in the past.
