Regarding the telephone configured as described above,
First, an example of the operation when receiving a call will be described based on the flowcharts shown in FIGS. 4 and 5.

When the user gives a registration instruction using the operation panel 15 and inputs a telephone number,
When the cola ID arrives from the communication line 1 and is detected by the cola ID circuit 14 (step F1) in the state where the data shown in (a) is stored in the storage circuit 16, a signal based on the detection result. Is the external input unit 18
The telephone number of the other party included in the caller ID is stored in the temporary storage area of the storage circuit 16 based on the detection signal from the caller ID circuit 14 supplied to the central control unit 18e (step F2) and the storage circuit. Predetermined information is read from 16 and it is determined whether the encryption setting is turned on (step F3).

At this time, when it is determined that the encryption setting is turned on in the central control unit 18e (step F3), the central control unit 18e causes the other party's telephone stored in the temporary storage area of the storage circuit 16. When the number is compared with the telephone number stored in the data area of the storage circuit 16 (step F4) and it is determined that there is a matching telephone number, the central control unit 18e encrypts the matching telephone number. At the same time (step F5), the muting of the mute circuits 5 and 10 and the encryption of the encryption circuits 7 and 12 are turned on by the external control unit d to prohibit the call using the speaker 8 and the microphone 9. (Step F
6) After that, the external control unit d drives the display circuit 17 based on the encrypted telephone number in the central control unit 18e to display the encrypted telephone number (step F).
7).

Before the Coke ID is received,
If the encryption setting is turned off (step F3), or if the telephone number matching the telephone number based on the cola ID is not stored in the storage circuit 16 (step F4), the telephone number based on the cola ID is set. Without encryption, the external control unit d drives the display circuit 17 based on the telephone number based on the cola ID to display the regular telephone number of the other party (step F7).

After that, when the incoming signal is detected by the incoming detection circuit 13 (step F8), a signal based on the detection result is supplied to the external input section 18a, and the central control section 1 is operated.
8e is based on the detection signal from the incoming detection circuit 13,
A ringer or the like (not shown) is driven to notify the incoming call (step F9).

At the time of this incoming call notification, the user judges that the telephone number displayed by the display circuit 17 is encrypted and operates the operation panel 15 to input the personal identification number, and the operation panel is operated. When the personal identification number input by 15 is recognized by the panel monitoring unit 18b (step F10), the central control unit 18e recognizes the personal identification number recognized by the panel monitoring unit 18b and the personal identification number stored in the storage circuit 16. It is determined whether or not they match (step F11). Only when it is determined that they match, the telephone number is decrypted (step F12), and the regular telephone number is displayed by the display circuit 17, and the external control unit The speaker 8 is turned off by muting the mute circuits 5 and 10 turned on by d or turning off the encryption of the encryption circuits 7 and 12. Releasing the call prohibition by fine microphone 9 (step F13).

Incidentally, with regard to the operation for judging the input of such a personal identification number (steps F10 to F12), the same operation control is carried out even after shifting to the talking state.

On the other hand, when the user responds to the incoming call notification by instructing the off-hook by the operation of picking up the handset including the speaker 8 and the microphone 9 or the operation of the operation panel 15 (step F14), the hook switch 3 is activated. Off-hook to close the communication line 1, shift to a call state with the other party's telephone, and the user does not respond to the incoming call notification, the other party gives up the call and stops dialing, etc.
When the incoming signal does not arrive further and is detected by the incoming detection circuit 13 (step F15), a signal based on the detection result is supplied to the external input unit 18a,
Based on the detection signal from the incoming detection circuit 13, the central control unit 18e turns on / off the data stored in the storage circuit 16 and mute in the mute circuits 5 and 10 and turns on the encryption in the encryption circuits 7 and 12. / OFF is returned to the initial state (step F16), and the state shifts to the standby state.

Therefore, according to the above operation control, the cola I
When the telephone number based on D and the telephone number stored in the storage circuit 16 match, the display of the other party's telephone number and the call with the other party can be prohibited, and unless the personal identification number is input, the other party It is possible to prevent the display of the other party's telephone number and the call to the other party, and for the other party who has not been set in advance, the telephone number etc. is displayed at the time of alerting the incoming call, preventing mischievous calls and Preliminary preparations can be done accurately.

A method for comparing telephone numbers and encryption,
And, if one method of comparing the personal identification numbers is represented in hardware,
As shown in FIG. 2, an encryption registration memory A that stores a telephone number to be encrypted, a temporary storage memory B that stores a telephone number of the other party based on a cola ID, and an encryption registration memory A.
The comparison search unit C for comparing and searching the telephone number stored in the above and the telephone number based on the cola ID, and the matching telephone number in the comparison search unit C are converted from decimal numbers to binary numbers 10
A bit-to-binary number conversion unit D, a bit-to-bit exchange unit E for exchanging the upper bit direction and the lower bit direction of the binary number data converted by the decimal-to-binary number conversion unit D, and bit exchange in the bit exchange unit E. A delay unit F that gives such a time delay to the binary number data converted by the decimal number → binary number conversion unit D, and an output of the bit replacement unit E and an output of the delay unit F, ExOR (Exclusive OR /
Exclusive OR circuit) G and the output data of ExORG is 2
Binary number to decimal number conversion unit H to convert from decimal number to decimal number
And a personal identification number input section I for inputting a personal identification number, and a comparison section J for comparing the personal identification number from the personal identification number input section I with the telephone number stored in the temporary storage area B and outputting a coincident telephone number. It can be configured by (and the switch in the drawing shall automatically switch to the one that has input).

According to such a hardware configuration,
For example, when "1234" is stored in the encryption registration memory A as the telephone number to be encrypted, when the cola ID representing "1234" is detected as the other party's telephone number, the other party's telephone number is detected. "1234" is stored in the temporary storage memory B, and is compared and searched by the comparison / retrieval unit C with the telephone number stored in the encrypted registration memory A. Since there is a matching telephone number, the telephone number "1234" Is output from the match output.

Then, the decimal number data such as "1234" from the coincidence output of the comparison and retrieval section C is a decimal number →
After being converted into binary data such as “1011010010” by the binary number conversion unit D, it is converted into data such as “0100101101” by the bit replacement unit E and delayed by the delay unit F, and then the two data Based on ExORG, "111111"
Binary number data such as “1111” is output, and the output is converted by the binary number → decimal number conversion unit H into decimal number data such as “1023” and output as display data.

On the other hand, when "1234" is input by the personal identification number input section I in such a state, the input "1234" and "1234" stored in the temporary storage memory B are compared with each other by the comparison section J. Are compared, and since they match, the number “1234” is output from the match output and is output as display data.

For example, when the caller ID "1234" is stored in the encryption registration memory A as the telephone number to be encrypted and the caller ID "2345" is detected as the telephone number of the other party, , Nothing is output from the match output of the comparison search unit C, and “234
5 ”is output, and this output is output as display data.

Next, another example of the operation at the time of an incoming call in the telephone configured as described above will be described based on the flowcharts shown in FIGS. 6 and 7.

When the user gives a registration instruction through the operation panel 15 and inputs a telephone number and a personal identification number and selects a display character, the data shown in FIG. 3B is stored in the storage circuit 16. In this state, the cola ID arrives from the communication line 1 and the cola I
When detected by the D circuit 14 (step F21),
A signal based on the detection result is supplied to the external input unit 18a, and the central control unit 18e, based on the detection signal from the cola ID circuit 14, stores the other party telephone number included in the cola ID in the temporary storage area of the storage circuit 16. In addition to storing (step F22), predetermined information is read from the storage circuit 16 to determine whether the encryption setting is turned on (step F23).

At this time, when it is determined that the encryption setting is turned on in the central control unit 18e (step F23), the central control unit 18e causes the other party's telephone stored in the temporary storage area of the storage circuit 16. Number and memory circuit 16
Of the image stored in the first data area of the storage circuit 16 when it is determined that there is a matching telephone number (step F24). The data is read, and the external control unit d drives the display circuit 17 based on the read image data to display the character based on the image data stored in the first data area (step F25).
At the same time, the first flag indicating the use of the first data area is set from "0" to "1" (step F26).

On the other hand, as a result of the comparison between the telephone number of the other party stored in the temporary storage area of the storage circuit 16 in the central control unit 18e and the telephone number stored in the first data area of the storage circuit 16, the same telephone number is obtained. If it is determined that there is no number (step F24), the central controller 18e determines the other party's telephone number stored in the temporary storage area of the storage circuit 16 and the telephone number stored in the second data area of the storage circuit 16. (Step F27), and when it is determined that there is a matching telephone number, the central control unit 18e reads the image data stored in the second data area of the storage circuit 16, and based on the read image data. The external control unit d is the display circuit 17
Is driven to display a character based on the image data stored in the second data area (step F2
At the same time, the first flag indicating the use of the second data area is set from "0" to "1" (step F29).

Before the cola ID is received,
If the encryption setting is turned off (step F23),
Alternatively, if a telephone number matching the telephone number based on the cola ID is not stored in both the first storage area and the second storage area of the storage circuit 16 (steps F24 and F27), display a predetermined character. No, cola id
The external control unit d displays the display circuit 1 based on the telephone number based on
7 is displayed, and the legitimate telephone number of the other party is displayed (step F30).

After that, when the incoming signal is detected by the incoming detection circuit 13 (step F31), a signal based on the detection result is supplied to the external input section 18a, and the central control section 18e detects the incoming signal from the incoming detection circuit 13. Based on the signal, a ringer or the like (not shown) is driven to notify the incoming call (step F32).

At the time of notification of the incoming call, the display circuit 17 displays a character to determine that the user is an incoming call from a predetermined partner, and operates the operation panel 15 to input a personal identification number, and the operation is performed. When the personal identification number input by the panel 15 is recognized by the panel monitoring unit 18b (step F33), the central control unit 18e makes a first decision.
It is determined which of the flag and the second flag is "1" (step F34).

Then, in the central controller 18e, the first
It is determined that the flag is "1" (step F34).
Then, the central control unit 18e determines whether the personal identification number recognized by the panel monitoring unit 18b and the personal identification number stored in the first data area of the storage circuit 16 match (step F35), and determines that they match. Only when the telephone number is set, the first flag is set from "1" to "0" (step F36), the telephone number stored in the temporary storage area of the storage circuit 16 is read, and the external device is read based on the read image data. The control section d drives the display circuit 17 to display the telephone number of the calling side (step F37).

On the other hand, the central controller 18e determines that the second flag is "1" (step F34).
Then, the central control unit 18e determines whether or not the personal identification number recognized by the panel monitoring unit 18b and the personal identification number stored in the second data area of the storage circuit 16 match (step F38), and determines that they match. Only when the telephone number is set, the second flag is set from "1" to "0" (step F39), the telephone number stored in the temporary storage area of the storage circuit 16 is read, and the external device is read based on the read image data. The control section d drives the display circuit 17 to display the telephone number of the calling side (step F37).

The central controller 18e is the panel monitor 18
When it is determined that the personal identification number recognized by b does not match the personal identification number stored in the storage circuit 16 (step F38), the external control unit d drives the display circuit 17 to display an error. May be.

When the user responds to the incoming call notification by instructing the off-hook by the operation of picking up the handset including the speaker 8 and the microphone 9 or the operation of the operation panel 15 (step F41), the central control is performed. Part 18e is first
Only when it is determined that either the flag or the second flag is set to "1" (step F42), and it is determined that either the first flag or the second flag is set to "1", The hook switch 3 is turned off-hook to close the communication line 1, and the state of communication with the partner telephone is entered.

Further, the user does not respond to the incoming call notification, the other party gives up the call and stops dialing, and the incoming signal does not arrive from the communication line 1. If detected (step F40), a signal based on the detection result is supplied to the external input unit 18a, and the central control unit 18e sets the first flag or sets the first flag based on the detection signal from the incoming detection circuit 13. 2 Flag settings are returned to the initial state (step F4
3) Shift to the standby state.

Therefore, according to the above operation control, the cola I
When the telephone number based on D and the telephone number stored in the storage circuit 16 match, the display of the other party's telephone number and the call with the other party can be prohibited, and unless the personal identification number is input, the other party It is possible to disable the display of the side telephone number and the call with the other party, and a large number of people can individually perform such setting.
