However, since the information of the registration number 110 is secret information, in the normal secret concealment mode, only the registration number is displayed as shown in FIG. It is not displayed, but is laid down, for example, by displaying an asterisk.

In the portable telephone terminal of this embodiment, a secret confirmation process is executed by the secret confirmation routine shown in FIGS. 3 and 4 as follows.

That is, in this secret confirmation processing routine 20, the terminal is in the normal secret confidential mode and the initial screen 7a indicating the date and time as shown in FIG. First, in step 21, the CPU 12 determines whether or not the telephone directory call key 64 has been pressed.

When the user wants to confirm a part of the information registered as secret information in the memory 15 in the secret mode, the user first presses the telephone directory call key 64.

When the CPU 12 determines in step 21 that a key other than the telephone directory call key 64 has been pressed, the process proceeds to step 22 and performs other processing corresponding to the pressed key. Return.

If it is determined in step 21 that the telephone directory call key 64 has been pressed, the CPU 12 proceeds to step 23
Then, the mode is set to the telephone directory mode, the telephone directory information is displayed on the LCD 7, and the process proceeds to step 24, where it is determined whether or not a key operation for calling the secret information is performed.

The CPU 12 initially calls, for example, the telephone directory information of the last registration number on the LCD 7, and when the user inputs a specific registration number with the dial key 61, the telephone directory information of the registration number is accordingly displayed on the LCD 7.
Call on 7.

The user can, for example, select a screen 7e shown in FIG.
In order to confirm the secret information of the registration number 110 shown in FIG. If registration number 110 is directly input, CPU 12 immediately determines that a key operation for calling secret information has been performed.

When the user inputs the registration number 109 or 111, for example, due to the wrong registration number of the secret information, the CPU 12 proceeds to FIG.
As shown in the screen 7b or 7f of (B) or (F), the non-secret information of the registration number 109 or 111 is displayed on the LCD 7, and it is determined that the key operation for calling the secret information has not been performed yet. Wait for the next operation by the user. The user sees the non-secret information of the registration number 109 or 111 displayed on the LCD 7 and presses the down key 66 or the up key 65. As a result, the CPU 12 determines that a key operation for calling secret information has been performed.

If it is determined in step 24 that the key operation for calling the secret information has been performed, the CPU
Next, at step 25, the registration number of the secret information is displayed on the LCD 7. That is, as shown in a screen 7c of FIG. 5C, only the registration number 110 is displayed, and the secret content is not displayed, but is displayed by, for example, an asterisk.

Next, in step 26, the CPU 12 determines whether or not the secret confirmation key 67 has been pressed. The user presses the secret confirmation key 67 when trying to confirm the secret content of the secret information in which only the registration number is displayed.

If the CPU 12 determines in step 26 that a key other than the secret confirmation key 67 has been pressed, it proceeds to step 27, performs other processing corresponding to the pressed key, and returns to step 21. .

At step 26, the secret confirmation key 67
When it is determined that is pressed, the CPU 12 proceeds to step 28 to display a lock code input screen 7d on the LCD 7 as shown in FIG. The user sees this and inputs a lock code consisting of a four-digit number registered in advance using the dial key 61.

Next, in step 29, the CPU 12 determines whether or not the input lock code is correct.
If it is determined that the lock code is not correct, the process proceeds to step 31, and after performing processing such as displaying a screen indicating that the lock code is incorrect on the LCD 7, the process proceeds to step 2.
Return to 8.

If it is determined in step 29 that the input lock code is correct, the CPU 12 proceeds to step 3

The secret content of the secret information is displayed on D7, and the process proceeds to step 33 to determine whether or not the transmission key 68 has been pressed.

The user looks at the displayed secret content and presses the call key 68 when calling the telephone number.

When it is determined in step 33 that the transmission key 68 has been pressed, the CPU 12 proceeds to step 34, performs a transmission process to the telephone number displayed on the LCD 7, and further proceeds to step 35. , Wait for the call to end, and when the call ends, go to step 36,
The secret confirmation mode is released, that is, the mode is returned to the secret mode, the initial screen 7a as shown in FIG. 5A is displayed on the LCD 7, and the process returns to step S21.

Therefore, after the end of the call, the secret property of the information registered in the memory 15 as the secret information is maintained without the user pressing the secret concealing key 63.

If it is determined in step 33 that the transmission key 68 has not been pressed, the CPU 12 proceeds to step 37
The program proceeds to step 32, where it is determined whether or not a predetermined time has elapsed since the contents of the secret were displayed on the LCD 7 in a step 32.
If it is determined that the predetermined time has elapsed, then step 36
To release the secret confirmation mode, that is, return to the secret mode, and display on the LCD 7 as shown in FIG.
The initial screen 7a as shown in (A) is displayed, and the process returns to step 21.

Therefore, after confirming the secret information,
Even if the user does not press the secret concealment key 63, the secret property of the information registered in the memory 15 as the secret information is maintained.

After the secret content is displayed on the LCD 7 in step 32, the user can be allowed to modify the secret content. In this case,
Immediately after the correction by the user or after a certain period of time, the mode automatically returns to the secret mode.

In the above example, after the call is made, the system automatically returns to the secret mode after waiting for the end of the call. However, once the call is started, it is not necessary to display the secret contents. Thereafter, after the start of the call, the mode may be automatically returned to the secret mode.
