Next, regarding the operation of the above-described configuration, in particular, when the power supply is in the on state (starting state), the control circuit 16 causes the S
In the state where the IM card mode is set, the SIM card 8 is stored in the main body case 9 of the handset 5 of the telephone main body 2 in the vehicle-mounted telephone device 1, and S
The processing executed by the control circuit 16 when the IM card 8 and the in-vehicle telephone device 1 are electrically connected will be described with reference to the flowchart shown in FIG. 4 and also FIG.

In the explanation, the in-vehicle telephone device 1 and the SIM card 8 used in the present process,
In order to distinguish the vehicle-mounted telephone device 1 and the SIM card 8 used in the previous (previous) processing from this, the vehicle-mounted telephone device 1 and the SIM card 8 used in this processing are respectively referred to as a vehicle-mounted telephone. In addition to the device A and the SIM card B, the vehicle-mounted telephone device 1 and the SIM card 8 used in the previous processing are referred to as a vehicle-mounted telephone device C and a SIM card D, respectively.

First, the control circuit 16 of the in-vehicle telephone device A
Is executing a main routine (not shown) waiting for a key operation for outgoing call processing or a key operation for incoming call processing.
When a detection signal is given from the IM card interface unit 21, it detects that the SIM card B and the in-vehicle telephone device A are electrically connected, exits the main routine, and performs the specific information transfer process shown in FIG. Transition.

Now, the control circuit 16 which has shifted to the specific information transfer processing first executes the processing for discriminating the SIM card B. Specifically, the control circuit 16 is configured as shown in FIG.
As shown in (c), by transmitting a request signal (RQ1) to the SIM card B, the card serial number (IDb) of the essential information stored in the SIM card B is received from the SIM card B. (Step S
1). Then, the control circuit 16 compares the received card manufacturing number (IDb) with the card manufacturing number stored in the storage unit 19 of the self (vehicle-mounted telephone device A) at that time (step S2).

Here, if the SIM card D different from the SIM card B was used together with the vehicle-mounted telephone device A at the previous time, the storage unit 19 of the vehicle-mounted telephone device A is stored in FIG.
As shown in (a), since the card manufacturing number (IDb) of the SIM card B is stored instead of the card manufacturing number (IDb) of the SIM card B, the control circuit 16 in step S3 It is determined to be “NO”, and the process proceeds to step S4.

The control circuit 16 having moved to step S4,
The card manufacturing number of the SIM card B (ID
b), not the SIM card D serial number (ID
Since d) is stored, the specific information stored in the SIM card D may be stored instead of the specific information stored in the SIM card B. The specific information stored in the card B is transferred to the storage unit 19 of the vehicle-mounted telephone device A through the above-mentioned serial communication line and stored (overwritten) in a predetermined storage area.

The control circuit 16 uses the SIM card B
, The handset manufacturing number (ID
a) is transmitted and stored (step S5), and then the process returns to the main routine (returns).

On the other hand, if the SIM card B was used together with the vehicle-mounted telephone device A in the same manner as this time, the storage unit 19 of the vehicle-mounted telephone device A stores in FIG. As shown in (b) and (c), since the card manufacturing number (IDb) of the SIM card B is stored, the control circuit 16 returns "YES" in step S3.
Then, the process proceeds to step S6.

The control circuit 16 having moved to step S6
The card manufacturing number of the SIM card B (ID
b) is stored, so at the time SIM
Since it is possible that the same specific information as the specific information stored in the card B is stored, then,
The following processing is executed.

That is, the control circuit 16 operates as shown in FIG.
As shown in (c), the handset serial number stored in the SIM card B is received from the SIM card B by transmitting the request signal (RQ2) to the SIM card B. Then, the control circuit 16 compares the received handset manufacturing number with the own handset manufacturing number (IDa) stored in the storage unit 19 (step S7).

Here, if the SIM card B is used together with another vehicle-mounted telephone device C between the previous processing and the current processing, the SIM card B is shown in FIG. 5 (b). As described above, the handset manufacturing number (IDa) of the in-vehicle telephone device A
Instead of the handset serial number (ID
c) is stored and the content of the specific information stored in the SIM card B may be rewritten accordingly, so that the control circuit 16 returns “NO” in step S8. ", And the process proceeds to step S4 described above.

Then, in step S4, the control circuit 16 transfers the specific information stored in the SIM card B to the storage section 19 of the vehicle-mounted telephone device A by the serial communication line as in the above-described processing. Transfer and store (overwrite) in a predetermined storage area.

On the other hand, if the SIM card B is not used with the other vehicle-mounted telephone device C between the previous processing and the current processing, that is, the SIM card B is continuously used with the vehicle-mounted telephone device A. If used, SIM card B
As shown in FIG. 5C, since the handset manufacturing number (IDa) of the vehicle-mounted telephone device A used together last time is stored, the control circuit 16 at this time, in step S8. It is determined to be "YES", and thereafter, the process is returned to the main routine without executing any process.

In this way, the control circuit 16 causes the SIM card 8 and the in-vehicle telephone device 1 to be electrically connected each time.
The card manufacturing number and the handset manufacturing number stored in the SIM card 8 and the card manufacturing number and the handset manufacturing number stored in the storage unit 19 of the handset 5 of the vehicle-mounted telephone device 1 are respectively identified, Whether or not the specific information stored in the SIM card 8 indirectly matches the specific information stored in the storage unit 19 of the vehicle-mounted telephone device 1 based on the result of the identification. Then, it is determined whether or not the specific information stored in the SIM card 8 is transferred to the storage unit 19 and stored.

In this case, the case where the SIM card 8 is housed inside the main body case 9 of the handset 5 when the power is turned on has been described, but the present invention is not limited to this. Even when the power is turned on when 8 is stored inside the main body case 9 of the handset 5, the same processing as this is executed.

As described above, according to this embodiment, when the SIM card 8 is electrically connected to the vehicle-mounted telephone device 1 when the power is on (starting state), the specific information stored in the SIM card 8 is Since it is configured to be transferred to and stored in the storage unit 19, when the user thereafter performs a predetermined key operation for reading the specific information of the SIM card 8, the SIM card 8 is stored at this time. The specific information was
Since it has already been transferred from the M card 8 to the storage unit 19 and stored therein, it is never read out from the SIM card 8.
It will be read from the storage unit 19. by this,
The time required to read the specific information from the SIM card 8 can be shortened, and the usability can be improved.

In particular, in the present embodiment, the card manufacturing number and the handset manufacturing number stored in the SIM card 8 and the card manufacturing number stored in the storage unit 19 of the handset 5 in the vehicle-mounted telephone device 1 and the handset manufacturing number. The matching of the handset serial numbers is set as a predetermined condition, and when the predetermined condition is satisfied, the process described above, that is, S
Since the processing in which the specific information stored in the IM card 8 is transferred to and stored in the storage unit 19 is invalidated, unnecessary processing can be omitted. As a result, usability can be further improved, and further,
It is possible to reduce power consumption.

The present invention is not limited to the above embodiment, but can be modified or expanded as follows. The communication device is not limited to a vehicle-mounted telephone device, but may be, for example, a mobile telephone device of a type into which an IC card (SIM card) is inserted, a public telephone device of a type into which an IC card is inserted, or a type of IC card to be inserted It may be applied to a general telephone device.

The IC card identifier and the communication device identifier are not limited to the card manufacturing number and the handset manufacturing number, respectively, and a wireless device manufacturing number unique to the wireless device may be used. It is also possible to adopt another discriminable item.
