Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a card-type telephone system configured such that a card-type telephone device communicates with an IC card via a card interface unit, obtains necessary ID information from the IC card, and makes a telephone call by radio telephone, and the system The present invention relates to an IC card and a card-type telephone device used in the field.
[0002]
[Prior art]
For example, when a user purchases a car phone device or a mobile phone device, ID information data necessary for the user to make a call is assigned to each phone device. The ID information data is written and stored in a non-volatile storage means such as an EEPROM inside the device via a dedicated interface, and the telephone device in which the ID information data is written can actually be used. It becomes. Therefore, if the user wants to change the ID information at a later date, the user needs to go to a store or service shop to change the ID information written in the telephone device. It was very inconvenient.
[0003]
In addition, when the telephone device is built in a navigation device, a radio unit, or the like to form a module, there is a possibility that the telephone device cannot be taken out.
[0004]
As a solution to such a problem, a system using a card type telephone device has been considered. The card-type telephone device includes a card interface to which an IC card as an external storage device can be connected. Then, the ID information data is stored in the IC card, and if the user obtains the IC card and connects it to the apparatus main body, the telephone number stored in the IC card is stored in the RAM on the apparatus main body side. It is configured to be transferred to the means to make a call. Therefore, the ID information can be easily changed, and moreover, a plurality of ID information can be properly used by one telephone device as necessary.
[0005]
Further, it is considered that the card type telephone apparatus as described above is applied to a car telephone apparatus. For example, when a card-type telephone device is incorporated in a car in advance and the user wishes to use the car phone as an option when purchasing the car, an IC card storing ID information data is supplied from the dealer. Conventionally, an employee of a telephone device store writes ID information data at a store. In this case, for example, an employee of a dealer can also write ID information data at another store. Furthermore, a user who has acquired an IC card can use it as an automobile telephone device by connecting the IC card to a card type telephone device.
[0006]
In other words, assuming that an automobile telephone unit (sold separately) will be installed later in the automobile, the interior of the vehicle must be complicated due to the installation of each component and the routing of wiring. Therefore, if the card-type telephone device is incorporated in the car in advance as described above and the function is activated by the user acquiring the IC card, the interior design of the vehicle compartment is unified and the space is obtained. Makes it more functional and enhances aesthetics.
[0007]
[Problems to be solved by the invention]
However, the conventional card-type telephone system is based on the idea that the IC card and the card-type telephone device should be used together. When using the card-type telephone device, the IC card is always used as the main body of the telephone device. It is configured on the assumption that it will be installed. Therefore, when there is a possibility that the user uses the telephone device, the IC card has to be always mounted on the telephone device, which is troublesome.
[0008]
On the other hand, most of them are security problems, etc., and writing ID information is only serviced by the telephone device store, and it is impossible to purchase only the telephone device or write only the ID information later. It was.
[0009]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a card-type telephone system capable of easily changing ID information without always mounting an IC card on the apparatus body, in addition to the conventional system. An object is to provide an IC card and a card type telephone device.
[0010]
[Means for Solving the Problems]
According to the card-type telephone system of claim 1 or 5, the card-side control means transfers the ID information data necessary for making a call read from the storage means to the card-type telephone apparatus side via the interface unit. The ID information data stored in the storage means is erased (Claim 1), or the transfer of subsequent ID information data is prohibited (Claim 5). Then, the apparatus-side control means stores the ID information data transferred from the IC card via the card interface unit in the nonvolatile storage means.
[0011]
That is, if the IC card is temporarily connected to the card type telephone device to transfer the ID information data, the ID information data is stored in the non-volatile storage means on the card type telephone device side. Therefore, there is no need to always connect the IC card to the apparatus main body, and the user does not need to always carry the IC card in preparation for using the card type telephone device, so that convenience can be improved.
[0012]
If an IC card in which different ID information is stored is supplied, the user can easily change the ID information. In addition, after the ID information data is stored in the card-type telephone device body, the ID information data stored in the storage means of the IC card is deleted (Claim 1) or cannot be read out. (Claim 5) It is possible to ensure the security of the personal information of the user.
[0013]
According to the card type telephone system of claim 2 or 6, the apparatus side control means determines whether or not the data value of the ID information transferred from the IC card is normal, and if it is normal, the IC ID information stored in the storage means when the card-side control means receives the erasure permission signal or the transfer prohibition signal by transmitting an erasure permission signal (claim 2) or a transfer prohibition signal (claim 6) to the card. Data is erased (Claim 2), or transfer of ID information data is prohibited (Claim 6).
[0014]
Accordingly, when it is confirmed that the ID information data stored on the IC card side is normally read by the card-type telephone device side, deletion (claim 2) or transfer is prohibited (claim 6). Therefore, it is possible to prevent the ID information data from being erased (claim 2) and being prohibited from being transferred (claim 6) even though the reading of the ID information data is abnormal.
[0015]
According to the card type telephone system of the third aspect, since the device-side control means uses the IC card from which the ID information data has already been deleted as the external memory, it can be registered as, for example, a telephone book or a memory dial. The number of cases can be increased.
[0016]
According to the card type telephone system of the fourth aspect, when the user performs an operation for issuing an ID information erasure command, the apparatus side control means is nonvolatile with respect to the IC card in which the ID information data has already been erased. The ID information data stored in the storage means is transferred, and the ID information data stored in the storage means is controlled to be erased. The card side control means transfers the ID information data transferred by the apparatus side control means. To write to the storage means.
[0017]
That is, when the user determines that the currently used ID information is unnecessary and issues an erasure command, the ID information data of the card type telephone device is transferred to the IC card, and then the ID information data Is erased. Since the ID information data transferred to the IC card is written again in the storage means on the IC card side, the ID information unnecessary for the user can be collected by the IC card. It is also possible to reuse the IC card.
[0018]
According to the card type telephone system of the seventh aspect, the apparatus-side control unit stores the ID information data transferred from the plurality of IC cards in the non-volatile storage unit, and according to the user's selection operation, Since any one of a plurality of ID information data stored in the storage means can be selected and used, the user can use the ID information properly as necessary. Therefore, for example, a plurality of users can perform billing processing or the like for each user by using one telephone apparatus using different ID information.
[0019]
According to the IC card of the eighth aspect, when used in the card type telephone system according to any one of the first to eighth aspects, when the ID information data is stored in the card type telephone device body, the storage means Since the ID information data stored in is erased or cannot be read out, it is possible to ensure the security of the personal information of the user.
[0020]
According to the card type telephone device of the ninth aspect, the data transferred from the IC card is stored in the nonvolatile storage means when used in the card type telephone system according to any one of the first to eighth aspects. Therefore, it is not necessary to always connect the IC card to the apparatus main body, and convenience can be improved.
[0021]
According to the card type telephone apparatus of claim 10 or 14, the control means stores the ID information data including the telephone number read from the storage means of the IC card via the card interface unit on the non-volatile storage means on the apparatus side. Remember me. Then, the ID information data stored in the storage means of the IC card is deleted (Claim 10), or the stored ID information data cannot be read (Claim 14).
[0022]
Therefore, similarly to the first or fifth aspect, it is not necessary to always connect the IC card to the apparatus main body, and the user can easily change the ID information. And the security regarding a user's personal information is securable.
[0023]
According to the card type telephone device of claim 11 or 15, the control means determines whether or not the data value of the ID information read from the storage means of the IC card is normal. The ID information data stored in the storage means of the card is erased (Claim 11), or the ID information data cannot be read (Claim 15). Accordingly, as in the case of claim 2 or 6, it is possible to prevent the ID information data from being erased (claim 11) even if the reading of the ID information data is abnormal (claim 11). can do.
[0024]
According to the card type telephone device of the twelfth aspect, the control means uses the IC card from which the ID information data has already been erased as the external memory. The number of items that can be registered can be increased.
[0025]
According to the card type telephone system of the thirteenth aspect, when the user performs an operation for issuing an ID information deletion command, the control means is nonvolatile with respect to the IC card in which the ID information data has already been deleted. Since the ID information data stored in the storage means is transferred and written, and the ID information data stored in the storage means is deleted, the ID information unnecessary for the user is collected by the IC card as in the case of claim 4. In addition, the IC card can be reused.
[0026]
According to the card type telephone device of the sixteenth aspect, the control means stores the ID information data transferred from the plurality of IC cards in the non-volatile storage means, respectively, and the storage means according to the user's selection operation. Since any one of a plurality of ID information data stored in the device can be selected and used, for example, as in claim 7, for example, a plurality of users can change one telephone device to a different ID information. By using them separately, billing processing and the like can be performed for each user.
[0027]
According to the card type telephone device of the seventeenth aspect, since the card type telephone device is mounted on the automobile and configured as the automobile telephone device, for example, the card type telephone device is previously incorporated in the automobile and the user can optionally use the automobile telephone. If desired, it is possible to easily configure a system in which the ID information stored in the IC card is given to the telephone device side via the card interface unit to activate the function.
In addition, similarly to the first or fifth aspect, the user need not always carry the IC card with the telephone device, and convenience can be improved.
[0028]
DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. FIG. 3 is a functional block diagram showing the electrical configuration of the automobile telephone device 1. An automobile telephone device (card type telephone device) 1 includes a radio device 3 for performing communication with other telephone devices via an antenna 2, a cradle 4 connected to the radio device 3, and a cradle 4. The handset 5 is detachably mounted.
[0029]
The wireless device 3 and the cradle 4 are connected via a handset 5 by a reception voice line RA for transmitting a reception voice of a call voice and a transmission voice line TA for transmitting the transmission voice. The wireless device 3 and the handset 5 are connected via serial communication lines SL1 and SL2 for transmitting various control serial signals.
[0030]
The handset 5 buffers the serial signal transmitted by the serial communication lines SL1 and SL2 that are inserted in the reception voice line RA and the transmission voice line TA and control the reception voice and the transmission voice. A serial signal control unit 7 that performs operation, an operation unit 8 that outputs operation signals in response to operations of various key switches (not shown), and a controller (device side) that receives various signals output from these signals and performs control based on the various signals Control means) 9 is incorporated. The controller 9 includes an EEPROM 9a which is a nonvolatile storage means.
[0031]
Also, the cradle 4 is inputted to the receiving amplifier 10 for amplifying the received voice, the speaker 11 for outputting the received voice amplified by the receiving amplifier 10, the microphone 12 to which the voice of the caller is inputted, and the microphone 12. A transmission amplifier 13 for amplifying the voice is incorporated. That is, the built-in speaker 11 and the microphone 12 in the cradle 4 are configured so that a so-called hands-free call of the automobile telephone device 1 by a vehicle occupant is possible.
[0032]
In addition, the cradle 4 is provided with a connector 13, and a card reader (card interface unit) 14 is detachable via the connector 13. The card reader 14 is connected to a SIM card (IC card) 15 and is connected to the connector 13 only when it is necessary to transfer data between the SIM card 15 and the controller 9. It has become.
[0033]
Here, FIG. 5 shows an example of a state in which the automobile telephone device 1 is mounted on the automobile 16. For example, the cradle 4 and the handset 5 are disposed between a driver seat and a passenger seat in the passenger compartment, and the antenna 2 and the radio device 3 are disposed at the rear portion of the automobile 16.
[0034]
FIG. 4 is a functional block diagram showing an electrical configuration of the SIM card 15. The SIM card 15 includes a CPU (card side control means) 17, a system control logic 18, a ROM 19, a RAM 20, an EEPROM (storage means) 21, an I / O port (interface unit) 22, and the like.
[0035]
The ROM 19 stores a control program for the CPU 17, and the EEPROM 21, which is a rewritable nonvolatile memory, includes, for example, a card manufacturing number (or a serial number that uniquely identifies the card), an access authentication number (so-called telephone number). ), Password, SIM holder (user) information (free area), and the like. These pieces of information stored in the EEPROM 21 are collectively referred to as ID information. However, the above is an example, and the ID information may be the minimum information necessary for making a call. The RAM 20 is used as a work area.
[0036]
The CPU 17 accesses the memories 19 to 21 through the system control logic 18 and communicates with the outside (the automobile telephone device 1) through the I / O port 22 which is a serial port. ing.
[0037]
That is, the controller 9 of the automobile telephone device 1 is connected to the I / O port 22 of the SIM card 15 via the connector 13 and the card reader 14. The card reader 14 is an interface between the controller 9 and the SIM card 15. For example, the card reader 14 is configured to perform parallel / serial conversion on data when the controller 9 accesses the SIM card 15.
[0038]
When the CPU 17 of the SIM card 15 receives the control code issued from the controller 9 via the card reader 14 and the I / O port 22 or the like, the CPU 17 reads necessary data from the EEPROM 21 according to the control code, and the controller 9 side. To be transferred to.
[0039]
The controller 9 transmits the ID information to the base station side via the wireless device 3 prior to the call. Then, the base station side collates the transmitted ID information. If there is no problem as a result of the collation, the base station side permits the telephone call to the automobile telephone device 1. When the call is permitted by the base station, the controller 9 performs a procedure for establishing a call line with a call destination desired by the user, thereby enabling the call.
[0040]
Next, the operation of this embodiment will be described with reference to FIGS. FIG. 1 and FIG. 2 are flowcharts showing the control contents of the controller 9 on the automobile telephone device 1 side and the CPU 17 on the SIM card 15 side, and mainly show the part according to the gist of the present invention. In FIG. 1, the controller 9 first determines whether or not the SIM card 15 is connected to the connector 13 via the card reader 14 (step A1).
[0041]
For example, when the card reader 14 is connected to the connector 13 and the SIM card 15 is connected to the card reader 14, one of the input pins is high at the port on the controller 9 side. The level is changed from the low level to the low level, and the controller 9 performs the reference by referring to the level.
[0042]
In step A1, if the SIM card 15 is not connected (“NO”), the controller 9 proceeds to step A9 and determines whether or not the ID flag set in step A5 is set as will be described later. To do. If the ID flag is not set, “NO” is determined and the process returns to Step A1 and waits until the SIM card 15 is connected.
[0043]
As described above, if the SIM card 15 is connected during the loop of steps A1 and A9, the controller 9 determines “YES” in step A1, and the ID flag is set as in step A9. If it is not set (“NO”), the process proceeds to step A3. Then, a control code for reading the ID information is given to the SIM card 15 to read the ID information.
[0044]
Reference is now made to FIG. When the SIM card 15 is connected to the connector 13 via the card reader 14, the power is supplied from the automobile telephone device 1 side together with a reset signal, a clock signal, etc. to each built-in electrical component. Then, execution of the flowchart of FIG. 2 is started by the CPU 17.
[0045]
The CPU 17 stands by until the control code of the ID information read command is given from the side of the automobile telephone device 1 (step B1). When the control code is given (“YES”), the ID information data is read from the EEPROM 21. To the car telephone device 1 (steps B2 and B3). Subsequently, the CPU 17 determines whether or not an “OK code (erase permission signal)” indicating that the data transfer has been normally performed is received within a predetermined time from the automobile telephone device 1 side.
[0046]
Referring again to FIG. 1, when controller 9 reads the ID information data transferred from SIM card 15 in step B3 (step A3), controller 9 writes the ID information data in EEPROM 9a and stores it (step A4). ). Then, an error check is performed based on an error check code (for example, checksum) attached to the ID information data (step A5). As a result, if the data read from the SIM card 15 is normal (“ YES ”), the above-mentioned“ OK code ”is transmitted to the SIM card 15 (step A6). If there is an abnormality as a result of the error check, the process returns to step A3, and ID information data is read from the SIM card 15 again.
[0047]
When the controller 9 transmits “OK code” in step A6, the controller 9 sets an “ID flag” indicating that the ID information has been read from the SIM card 15 in the flag storage area of the RAM (not shown) (step A7). Processing is executed (step A8). Here, the normal process is a process such as start of a call as necessary. After executing the normal process, the process returns to Step A1.
[0048]
Referring to FIG. 2 again, when the CPU 17 of the SIM card 15 receives the “OK code” transmitted in step A6 from the automobile telephone device 1 side in step B4 within a predetermined time (“YES”), The ID information is erased by writing, for example, data “0” in all the areas where the ID information is stored (zero clear, step B5). Then, the process ends. If “OK code” is not received within the predetermined time in step B4 (“NO”), the process returns to step B1 and waits until the ID information data read command code is transmitted again from the car telephone apparatus 1 side. To do.
[0049]
Thereafter, the controller 9 of the automobile telephone device 1 performs the SIM car in step A1. 1 Regardless of whether 5 is connected (“YES”) or not (“NO”), it is determined whether or not the ID flag is set in steps A2 and A9. And the process proceeds to step A10. When the ID information data stored in the EEPROM 9a is read, the process proceeds to step A8.
[0050]
As described above, according to the present embodiment, the CPU 17 of the SIM card 15 transfers the ID information data necessary for making a call read from the EEPROM 21 to the car phone device 1 side via the I / O port 22. The ID information data stored in the EEPROM 21 is erased. The controller 9 of the automobile telephone device 1 stores the ID information data transferred from the SIM card 15 via the card reader 14 in the EEPROM 9a.
[0051]
That is, if the SIM card 15 is temporarily connected to the automobile telephone device 1 to transfer the ID information data, the ID information data is stored in the EEPROM 9a on the automobile telephone device 1 side. Accordingly, it is not necessary to connect the SIM card 15 to the main body of the telephone device 1 at all times, and the user does not need to always carry the SIM card 15 in preparation for using the car telephone device 1, thereby improving convenience. Can do.
[0052]
If a SIM card in which different ID information is stored is supplied, the user can easily change the ID information. In addition, the ID information data stored in the EEPROM 21 of the SIM card 15 is erased after the ID information data is stored in the main body of the automobile telephone device 1, so that security regarding personal information of the user is ensured. Can do. Accordingly, it is possible to reliably prevent two or more automobile telephone devices having the same ID information from existing. In addition, since the card reader 14 can be attached to and detached from the automobile telephone device 1 via the connector 13, the number of components arranged in the automobile 16 can be reduced.
[0053]
Further, according to the present embodiment, the controller 9 determines whether or not the data value of the ID information transferred from the SIM card 15 is normal. When the “code” is transmitted and the “OK code” is received, the CPU 17 deletes the ID information data stored in the EEPROM 21.
[0054]
Accordingly, since the ID information data stored on the SIM card 15 side is erased when it is confirmed that the car telephone apparatus 1 has read it normally, the reading of the ID information data is abnormal. Nevertheless, the data can be prevented from being erased. Then, if the reading of the ID information data is abnormal, the controller 9 reads the ID information data from the SIM card 15 again, so that the data can be read normally as much as possible.
[0055]
In addition, since the card-type telephone apparatus is configured as the automobile telephone apparatus 1, for example, when the automobile telephone apparatus 1 is incorporated in the automobile 16 in advance and the user desires to use the automobile telephone as an option, the SIM card 15 It is possible to easily configure a system in which the ID information stored in is transferred to the automobile telephone device 1 side and the function is validated.
[0056]
(Second embodiment)
6 and 7 show a second embodiment of the present invention. The same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted. Only different parts will be described below. The configuration of the second embodiment is basically the same as that of the first embodiment, and the control contents of the controller 9 on the side of the automobile telephone device 1 and the CPU 17 of the SIM card 15 are slightly different.
[0057]
That is, in FIG. 6, when the controller 9 determines “NO” in step A2, the controller 9 reads an area (for example, address 0) set as a flag storage area in the EEPROM 21 of the SIM card 15, and reads the read prohibition flag into the area. Is set (step A10). The read prohibition flag is a flag that is set by the CPU 17 of the SIM card 15 in step B6 described later.
[0058]
Here, referring to FIG. 7, when CPU 17 of SIM card 15 receives “OK code (in this case, transfer prohibition signal)” in step B4 and determines “YES”, it proceeds to step B6 instead of step B5. When, for example, data “1” is written in the flag storage area of the EEPROM 21 and the read prohibition flag is set, the process is terminated.
[0059]
Referring to FIG. 6 again, if the read prohibition flag is not set in step A11 ("NO"), the controller 9 proceeds to step A3 and performs the same processing as in the first embodiment. On the other hand, if the read prohibition flag is set in step A11 ("YES"), a process of notifying the user that reading of ID information from the SIM card 15 is prohibited and impossible (step A12) is performed. After the processing is completed, the processing is terminated.
[0060]
The process of notifying the user of the inability to read in step A12 is, for example, from the receiving speaker 11 arranged in the cradle 4, “Reading of ID information from this card is prohibited. Use other cards. Please do so by outputting a sound such as "Please do" or by turning on the LED.
[0061]
As described above, according to the second embodiment, when the CPU 17 transfers the ID information data read from the EEPROM 21 to the car telephone device 1 side, the flag for prohibiting the reading of the ID information data stored in the EEPROM 21 is set. The controller 9 checks whether or not the read prohibition flag is set before reading the ID information data from the SIM card 15, and reads the ID information data when the flag is not set. did.
[0062]
Accordingly, as in the first embodiment, after the ID information data is stored in the main body of the automobile telephone device 1, the ID information data stored in the EEPROM 21 of the SIM card 15 cannot be read out. Security for sensitive information.
[0063]
(Third embodiment)
8 and 9 show a third embodiment of the present invention. The same parts as those in the first embodiment are denoted by the same reference numerals and the description thereof will be omitted. Only the different parts will be described below. In FIG. 8 showing the electrical configuration, the controller 9 of the first embodiment is replaced with a controller (device-side control means) 23. Further, the connector 13 arranged in the cradle 4 is replaced with a connector (card interface unit) 24. In the second embodiment, a memory card (IC card) 25 is used instead of the SIM card 15 of the first embodiment.
[0064]
The memory card 25 is a card in which only an EEPROM (storage means) 26 storing ID information is incorporated as an IC. Accordingly, the card reader 14 is unnecessary, and the memory card 25 has a contact (interface unit) 25 a that is directly electrically connected to the connector 24. When the memory card 25 is connected to the connector 24, the address and data bus of the EEPROM 26 and each control signal line are directly connected to the bus and control signal line of the controller 23.
[0065]
Next, the operation of the third embodiment will be described with reference to FIG. If the controller 23 determines “YES” as a result of the error check in step A5,
In the first embodiment, for example, data “0” is written in all the areas where the ID information of the EEPROM 26 built in the memory card 25 is stored in the same manner as the processing performed by the CPU 17 of the SIM card 15 in step B5. If it is cleared to zero (step A13), the process proceeds to step A7. Note that since the CPU is not mounted on the memory card 25, there is no flowchart corresponding to FIG.
[0066]
That is, according to the third embodiment, when the controller 23 of the automobile telephone device 1A stores the ID information data read from the EEPROM 26 of the memory card 25 in the EEPROM 23a, the ID information data stored in the EEPROM 26 is cleared to zero. To erase. Therefore, the same effect as that of the first or second embodiment can be obtained.
[0067]
The present invention is not limited to the embodiments described above and illustrated in the drawings, and the following modifications or expansions are possible.
In the first embodiment, the connector 13 for connecting the card reader 14 is not limited to the one arranged in the cradle 4, for example, arranged in the radio device 3 arranged in the rear part of the automobile 16 and the rear trunk is arranged. You may make it open and connect. In this case, the controller 9 may be arranged on the wireless device 3 side. Further, in this case, a cable having the connector 13 may be routed from the wireless device 3 disposed in the rear part to the vehicle interior so that the connection with the card reader 14 is performed in the vehicle interior.
Further, communication between the card reader serving as the card interface unit and the controller 9 may be performed in a wireless manner.
The function of the card reader 14 may be incorporated in the controller 9 or may be incorporated on the side of the automobile telephone device 1 as a peripheral device of the controller 9.
[0068]
In this case, the SIM card 15 may be provided with a wireless communication function as an interface unit so that communication with the controller 9 is performed in a wireless manner.
The EEPROM 21 of the SIM card 15 after erasing the ID information may be used and thereafter used as an external memory card for storing a memory dial or the like. With this configuration, the storage capacity can be greatly increased.
Instead of performing an error check in step A5, the data read from the SIM card 15 in step A3 is temporarily written in, for example, a RAM work area before being written in the EEPROM 9a in step A4. If the result of the error check is OK, it may be written in the EEPROM 9a.
Also, an error check is performed on the car telephone device 1 side, and an OK code is output to the SIM card 15 side according to the result. After confirming the issuance of the OK code on the SIM card 15 side, the ID information data in the EEPROM 21 is erased. The method for prohibiting the transfer of the data may be performed as necessary, and steps A5, A6, and B4 may be deleted.
[0069]
The EEPROM on the side of the automobile telephone device 1 may be externally attached to the controller 9.
In the second embodiment, after step A12 is executed, the process may return to step A1.
Also in the case of the third embodiment, the controller 23 may set the read prohibition flag for the EEPROM 26 of the memory card 25 as in the second embodiment.
In order to further improve security, the read prohibition flag is set together with the card ID on a server or the like prepared on the system (network) side of the wireless telephone instead of setting the read prohibition flag on the SIM card 15 or the memory card 25. In this manner, the setting / reset of the card read prohibition flag may be determined by accessing the server. Alternatively, flags may be set on both the card and the server to check both.
Further, by providing a configuration in which a GPS (Global Positioning System) can be used in the card type telephone device, it may be possible to determine whether to set / reset the read prohibition flag only in a specific area.

Further, the first embodiment may be modified and configured as follows. When an operation for issuing an ID information deletion command is performed by the user in the operation unit 8, the controller 9 transfers the ID information data stored in the EEPROM 9 a to the SIM card 15 in which the ID information data has already been deleted. The ID information data on the EEPROM 9a is erased. Then, the CPU 17 of the SIM card 15 controls to write the ID information data transferred by the controller 9 in the EEPROM 21.
That is, when the user determines that the currently used ID information is unnecessary and issues an erasure command, the ID information data of the card type telephone device 1 is transferred to the SIM card 15, and then the ID information Information data is erased. Then, since the transferred ID information data is written again in the EEPROM 21 on the SIM card 15 side, the ID information unnecessary for the user can be collected by the SIM card 15. The SIM card 15 can be reused.
In addition, the third embodiment is similarly modified, and when the controller 23 performs the same operation by the user in the operation unit 8, the ID information data stored in the EEPROM 23a is already deleted. It is also possible to specify that data on the EEPROM 23a is erased by writing to the memory card 25 side.

In this case, for example, if “YES” is determined in step A1 of the flowchart of FIG. 1, the controller 9 displays a processing menu screen on a display unit (not shown), and selects “ID information processing” from among them. The user selects and processes “reading” the ID information from the card, “writing” the ID information to the SIM card 15, and “deleting” the ID information on the SIM card 15 side or the mobile phone device 1 side. You may make it do.
Further, for example, the controller 9 stores the ID information data transferred from the plurality of SIM cards 15 in the EEPROM 9a, and selects any one of the stored plurality of ID information data according to the user's selection operation. May be configured to be usable. If comprised in this way, a user can add and use ID information to the card-type telephone apparatus 1 as needed, so that, for example, a plurality of users can use different ID information for each telephone apparatus. By using them properly, billing processing and the like can be performed for each user.
The present invention is not limited to those applied to automobile telephone devices, and may be applied to mobile phone devices and the like.
