When a bell incoming call is received by this telephone device through an outside line, the bell receiving circuit 8 detects it through the capacitor C2 and sends a bell incoming signal to the CPU1. CPU
When the incoming call signal is input, the process proceeds from step 100 to step 110, and it is determined whether the caller's telephone number signal is input through the outside line.

The exchange of the telephone company sends, for example, a telephone number signal (FSK signal) indicating the telephone number of the calling party to the called party between the first bell signal and the second bell signal. . When the telephone number signal of the called party is input to the outside terminal, the telephone number signal is received through the capacitor C1 and the signal transformer T, and the filter circuit 9 and the demodulation circuit 10 are received.
Is operated to demodulate the telephone number data from the telephone number signal which is the FSK signal and send it to the CPU 1.

When the CPU 1 receives the telephone number data, it proceeds from step 110 to step 120 and stores the telephone number data of the calling party in the temporary memory 15.
Next, in step 130, the telephone number data is collated with the telephone number (a known telephone number of the user) stored in advance in the data file memory 14.

Then, in step 140, if the telephone number of the caller matches any of the known telephone numbers stored in advance in the data file memory 14, the process proceeds to step 150, and the matched telephone number. The name, address, etc. of the owner of the are displayed on the display unit 13. At this time, it may be displayed together with the telephone number.

Next, at step 160, the bell generation circuit 1
1 is operated to cause the speaker S to ring a second ring tone. The second ring tone is different from the first ring tone when the caller's telephone number is a number that does not match a previously stored known telephone number (tone, pitch, etc.). Sound).

On the other hand, if the caller's telephone number does not match any of the known telephone numbers stored in advance in the data file memory 14 in step 140, the process proceeds to step 170 and only that telephone number is entered. Is displayed on the display unit 13.

Next, in step 180, the bell generation circuit 1
1 is operated to cause the speaker S to ring the first ring tone. The first ring tone is a tone different from the second ring tone when the telephone number of the caller matches a previously stored known telephone number.

In this way, when the user receives an incoming call from an outside line, the user hears the ringing tone or looks at the display 13 to see if the calling party is a known person or if the calling party is known. You can easily recognize whether you are a stranger or not before picking up the handset 5. Therefore, the user looks at the name of the calling party, and if he / she wants to make a call, the handset 5
Should be raised.

When the user picks up the handset 5,
The hook switch HS is turned on, and the CPU 1 proceeds to step 1
From 90 to step 200, a command signal is output to the outside line control circuit 3, and the outside line control circuit 3 causes the transistor Q
2. Turn on Q1 and close the external line terminals with direct current. As a result, a call becomes possible, and the user holds the handset 5 and talks through the peach network circuit 4.

When the call ends, the user puts the handset 5 on the hook switch HS.
Is turned off. At this time, the CPU 1 proceeds from step 210 to step 220, outputs a command signal to the outside line control circuit 3, turns off the transistors Q2 and Q1 by the outside line control circuit 3, and opens the outside line terminal.

As described above, the above operation is repeated every time there is a bell incoming call through the outside line, and the telephone numbers of incoming calls are sequentially stored in the temporary memory 15. The stored data in the temporary memory 15 can be displayed on the display unit 13 at any time by operating the button of the operation unit 17.

Since all the telephone numbers of callers who receive an incoming call from an outside line while the user is away are stored in the temporary memory 15, the user is stored in the temporary memory 15 after returning home. The displayed telephone number can be displayed on the display unit 13, and if necessary, the telephone number can be dialed to make a call. At the time of making a call, a target telephone number can be automatically dialed by operating a button of the operation unit 17, and the telephone number of the other party who dialed automatically may be erased from the temporary memory 15.

In the above embodiment, if the telephone number of the calling party is not known, the first ring tone is sounded, but the ring tone may not be sounded at all.

If the telephone number stored in the temporary memory 15 is a known telephone number stored in the data file memory 14, its name and address may be stored together.
