It is considered that the telephone can be used as a general subscriber telephone.

In this case, an identification code (subscriber number or telephone number) peculiar to the telephone subscriber is stored in the ID card, and the identification code is used when a call is made with the mobile telephone mounted. Corresponding charges will be made.

By the way, a mobile phone using such an ID card can be used as a member of a different telephone subscriber only by replacing the ID card, so that it may be used jointly by a plurality of people.

[0005]

However, even if each telephone subscriber attaches his or her own ID card to the mobile telephone, he / she cannot see the subscriber number, so the ID card is certainly his / her own. I couldn't confirm if there was. Also,
It is conceivable to store not only the subscriber number but also personal data such as the name of each telephone subscriber in the ID card, and in order to confirm the contents, a predetermined operation for confirmation must be performed. There wasn't.

As information that can be handled by such a mobile phone system, in addition to voice services such as a normal voice call service and voice mail service (so-called voice mail), various information services (data services other than voice) Is being considered. On the other hand, I was not able to know the service that can handle ID cards.

Further, in the case where the subscriber number or personal data is stored in the main body memory and the ID card, it was not possible to recognize whether the subscriber number was read from the main body memory or the ID card. .

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a portable communication terminal that allows a subscriber of a removable storage medium to confirm unique information.

Further, according to the invention of claim 2, the subscriber-specific information stored in the storage medium has at least an identification code for identifying the subscriber, and the identification code is displayed on the display means. For example, at least what the identification code stored in the currently mounted storage medium can be recognized.

If the information unique to the subscriber is read from the storage medium by a key operation as in the third aspect of the present invention, for example, the identification information currently used when the power is turned on or when the call is made can be obtained. You can easily recognize something.

According to the invention of claim 4, in a portable communication terminal device in which a storage medium storing identification information for identifying subscribers is detachable, the identification information and the identification information of a plurality of subscribers are associated in advance. Storage means for storing information peculiar to the subscriber, search means for searching the storage means for information peculiar to the subscriber corresponding to the identification information obtained by reading the identification information from the storage medium, and peculiar to the subscriber retrieved by the search means And a display means for displaying the information.

Thus, the subscriber-specific information can be stored in the terminal, and the removable storage medium can be used as a removable storage medium in which the subscriber-specific information is not stored.

According to the invention of claim 5, in a portable communication terminal device having a removable storage medium storing identification information for identifying a subscriber, the identification information for identifying the subscriber is fixed to the terminal. Storage means, reading means for reading the identification information for identifying the subscriber from the storage medium or the storage means, and display means for displaying which of the storage medium or the storage means the identification information for identifying the subscriber has been read by the reading means. It was equipped with.

As a result, it is possible to recognize whether the currently used identification information is read from the internal memory of the terminal or read from the removable storage medium.

In the second embodiment, the identification code and personal data are displayed when the call key is pressed. However, the display is not limited to this, and may be displayed when a key other than the call key is operated.

Therefore, according to such an embodiment,
When the call key is pressed, the identification code and personal data are read out from the ID card or the main body memory and displayed on the display unit. With this, the user can know the contents of the identification code and the personal data from the displayed contents when making a call, and can recognize whether or not the attached ID card is his / her own ID card, and can surely identify himself / herself. It can be used as a billing phone.

Next, a third embodiment of the present invention will be described. Also in this case, the schematic circuit configuration of the mobile phone in the third embodiment is basically the same as that in the above-mentioned first embodiment, and the description thereof will be omitted.

However, in the ROM 12 of FIG. 3, as shown in FIG. 7, a name, a telephone number, an address, an address corresponding to an address (an address corresponding to a subscriber number stored in an ID card), Character data such as available services is stored. Then, the operation based on such a configuration will be described based on the flowchart shown in FIG.

For example, when the power switch 8n is turned on with the ID card 11 mounted, the standby state is entered. Then, when the transmission key 8a of the key input unit 8 is operated (step S40), a predetermined transmission process is performed and I
The address (for example, “01”) corresponding to the subscriber number stored in the D card 11 is read out, and the RAM 13 is read.
(Step S42).

Next, based on the address stored in the RAM 13, the ID / subscriber name table T stored in the ROM 12 is searched for a corresponding one (step S4).

On the other hand, when it is determined in step S76 that the identification code of the ID card 11 is not stored in the RAM 13 of the main body, the display unit 9 displays that the identification code of the ID card 11 is not present (step S80). For example, a message such as "No ID card identification code exists" is displayed. Then, the identification code is read from the ROM 12 of the main body (step S82), and the fact that it is the identification code of the main body memory is displayed (step S84). For example, as shown in FIG. 11, the "MEMORY" mark is turned off. Further, the identification code used in step S74 is I
ROM 12 of the main unit, which is not set on the D card 11 side
If it is determined that the identification code is set to the side, the identification code is read from the ROM 12 of the main body (step S82), and the fact that it is the identification code of the main body memory is displayed (step S84).
For example, as shown in FIG. 11, the "MEMORY" mark is turned off.

At this time, the display may be changed depending on whether the read identification code is public or self-employed. When the identification code to be read is public, that is, if it is a subscriber number, for example,
As shown in FIG. 11, the "PUBLIC" mark is displayed. In addition, the identification code to be read is a self-employed stick, that is,
If the CS-ID is used, for example, as shown in FIG.
The VATE mark is displayed.

As a result, the setting state of the identification code to be used can be recognized.
