[0001]

The present invention relates to a telephone device,
In particular, the card storing the unique identification information is made detachable to the telephone device main body, and when the identification information is read from the inserted card, a predetermined operation different from the case where the identification information cannot be read is executed. And a telephone device configured to perform the above operation.

[0002]

2. Description of the Related Art In recent years, a card storing unique identification information has been made detachable to a telephone apparatus main body, and when the identification information is read from the inserted card, the predetermined information is different from the case where the identification information cannot be read. A telephone device configured to perform the above operation has been considered. For example, it is conceivable that the basic telephone function itself cannot be used unless the card itself is mounted.

[0003] In this case, the function as a telephone device cannot be fulfilled unless a card is inserted, so that unauthorized use by anyone other than the card owner can be prevented. The usual usage of this type of telephone device is as follows. For example, when the power is turned on by a power switch or the like, the apparatus enters a state of waiting for the card to be mounted. When the card is inserted in this state, a unique identification number is read from the card, and if the use is permitted, a normal operation is started. In other words, you can use basic functions such as making and receiving calls, or if you have a special answering function, you can store message messages, or if you have an e-mail function, you can receive mail data. Can be stored. On the other hand, when ending the use, the power is turned off by a power switch or the like, and the card is removed. The reason for removing the card after turning off the power in this way is that the data in the card may be destroyed if the card is being accessed by the phone itself, for example. This is to prevent

[0004]

As described above, in a telephone device that performs a predetermined operation on the assumption that a card is inserted,
It is not necessary to perform the same operation during the period when the card is not mounted as during the period when the card is mounted.
For example, as described above, if the basic telephone function itself cannot be used unless the card itself is mounted, there is no need to supply the power supplied by the so-called power switch. Conversely, even when the card is not mounted, supplying power in the same manner as when the card is mounted leads to wasteful power consumption.

[0005] Therefore, it is effective to control the power supply depending on whether or not a card is mounted, in terms of reducing power consumption. Further, in this case, if the power supply can be automatically controlled in response to the insertion / removal of the card, the user does not need to operate the power switch, and the power switch itself is not required.

The present invention has been made in view of the above points, and a telephone capable of reducing power consumption and improving operability by performing state switching corresponding to insertion / removal of a card from / to a telephone device body. It is intended to provide a device.

[0007]

According to a first aspect of the present invention, there is provided a telephone device comprising: a storage device built in a card detachably mounted on a main body of the telephone device; It stores unique identification information. Further, data obtained during the operation can be stored in the data storage means of the telephone device main body. The card interface can be electrically connected to the card at least when the card is at a predetermined mounting position.

Therefore, when the card is mounted at a predetermined mounting position, the card interface is electrically connected to the telephone device main body, and the telephone device main body reads the identification information from the card. Then, when the identification information can be read, a predetermined operation different from the case where the identification information cannot be read (including the case where the card is not mounted, of course) is executed.
For example, it is conceivable that the card cannot be used unless the card itself is mounted. Or,
The operation content may be restricted.

As described above, the user can use the telephone device by installing his / her own card. In other words, when the user does not install the card, the user can use the telephone device. This means that the same operation as that described above need not be performed by the telephone device main body. Therefore, in the telephone device of the present invention, the mounting detection means detects that the card is mounted at the predetermined mounting position, and the removal detecting means detects that the card has moved in the direction to be removed from the predetermined mounting position. The state switching unit performs the following control. That is, when it is detected that the card has been mounted at the predetermined mounting position, the operation state of the telephone device body is switched to the normal state, and on the other hand, the card has been moved in the direction to be removed from the predetermined mounting position. If detected , the card consumes less power than in the normal state and

You can easily find out.

[0010] Also, speaking about the sleep state, the above-mentioned
It is natural that you do not access the card as you did
Thus, for example, it is conceivable to reduce the power consumption by supplying power to only a minimum part capable of detecting that the card has been inserted. this is,
It is assumed that if the card is not installed, it will be practically impossible to use it.When the card is installed, it is sufficient to supply power to each part and perform normal operation. Supplies power only to the minimum necessary parts.

According to the above premise, claim 4
As shown in FIG. In other words, if comprehensive control of each part of the telephone device itself is performed using a microcomputer, the operation clock frequency of the microcomputer is reduced by lowering the frequency of the operation clock in the sleep state from the normal state. Reduce power. If it just needs to be able to detect that the card has been inserted,
This is because the same response as in the normal operation is unnecessary.

As described above, power consumption is reduced by performing state switching corresponding to insertion / removal of a card from / to the telephone apparatus body, and power supply is automatically performed in response to insertion / removal of a card. In this case, the user does not need to operate the power switch, thereby improving the operability. In addition, the power switch itself is not required, which contributes to simplification of the configuration.

[0013]

[0014]

The unique identification information stored in the card may be, for example, the serial number of the card as described in claim 5, or may correspond to the owner of the card as described in claim 6. May be the telephone number given. The point is that it is only necessary to be able to distinguish the users, so that any serial number, that is, no duplicate number exists.

The card used in the present invention is:
As long as the storage means for storing the unique identification information is provided as described above and can be detachably attached to the telephone device main body, it is possible to use an IC card, a magnetic card, an optical card, or the like. Is also good. In the case of an IC card, the storage means is an IC memory. More specifically, an IC card having a microprocessor and capable of writing to the IC memory (in a narrow sense), and a memory card including only the IC memory as an integrated circuit Divided into In the present invention, any of them can be applied. Further, although writing is not possible on a magnetic card or the like, the present invention can be realized as long as the identification information is stored in at least the storage means, and can be used similarly. Although a card is described, it is actually portable even if it is not a card shape, and any other shape is applicable as long as it is relatively small. However, it can be said that a card shape is preferable in terms of portability and the like, as represented by an IC card and a magnetic card which are very widely spread at present.

As a general property, an IC card has a higher security function and a larger storage capacity than a magnetic card, so that versatility is improved. As described above, since it is an object of the present invention to prevent highly private data from being known to others, it is considered that using an IC card is more appropriate in that respect.

A typical example to which the telephone device of the present invention is applied is a wireless connection to a telephone line network such as a portable telephone device (so-called portable telephone or PHS) or a car telephone device. A mobile telephone device can be considered. Of course, the present invention can be similarly applied to a home telephone device or the like which is a fixed telephone device connected to a telephone network via a transmission line.

[0019]

Embodiments of the present invention will be described below with reference to the drawings. It is needless to say that the embodiments of the present invention are not limited to the following examples, and can take various forms as long as they belong to the technical scope of the present invention.

First, FIG. 1 is a schematic configuration diagram showing the entire configuration of a car telephone apparatus as one embodiment of the telephone apparatus of the present invention. As shown in FIG. 1, the car telephone device of the present embodiment
A telephone device main body 1, an automobile telephone radio (hereinafter simply referred to as a radio) 3 for communicating with another telephone device via an antenna 2, and an IC card mounted on the telephone device main body 1 for use. 5 is comprised. The telephone device body 1 is a telephone body (hereinafter, referred to as a cradle) 1.
3, a handset telephone receiver (hereinafter, simply referred to as a handset) 15 provided detachably on the cradle 13, and a hands-free telephone microphone (hereinafter, referred to as a hand-free microphone) provided near the driver's seat of the vehicle. ) 17, and the wireless device 3 is connected to the handset 15 of the telephone device body 1. Also,
The handset 15 is provided with a slot (not shown), and the IC card 5 is configured to be attached to the handset 15 by being inserted into the slot.

As shown in FIG. 2, the cradle 13 includes a speaker 27 for generating a ring tone when a call signal is received from another telephone device or outputting a voice from a called party during a hands-free call. A power supply circuit 70 converts a voltage (usually 10 V to 15 V) from the battery BT to a predetermined power supply voltage and supplies it to each part in the handset 15 and each part in the cradle 13, and a microcomputer 31 in the handset 15. Power supply circuit 7
A power supply control circuit 75 is provided to control power supply from 0 to each part, that is, to control power supply and stop. The microcomputer 31 in the handset 15 is connected to the power supply circuit 7 without the power supply control circuit 75.
0 is supplied directly.

The handset 15 of the telephone device body 1
And the wireless device 3 are connected to a voice line L for passing voice for communication.
A and a serial signal line LS through which various control serial signals such as a call signal pass.
The handset 15 includes an audio control unit 21 that amplifies an audio signal passing through the audio line LA, and a serial signal control unit 23 that buffers a serial signal passing through the serial signal line LS.

The handset 15 displays a call control unit 25 for switching between a hand-free call and a handset call, a message transmitted from another telephone device, an operation guide of the telephone device main body 1, an operation status, and the like. A display unit 22 comprising a liquid crystal display (LCD) for performing
Storage unit 24, card presence / absence detection switch 28, card interface unit (hereinafter referred to as card I / F unit) 29
, A microphone for handset communication (hereinafter simply referred to as a microphone) 41, a speaker 43 for outputting a voice from the other party during a handset call, and various key switches for dial input and selection of a call mode. Various operation units 45, a voice control unit 21, a display unit 22,
Serial signal control unit 23, storage unit 24, call control unit 2
5, a microcomputer 31 for controlling the card I / F unit 29 and the operation unit 45, respectively.

The handset 15 is turned on when the handset 15 is taken out of the cradle 13,
A selection switch for automatically selecting a handset call as a call mode is provided. The card I / F section 29
Is an interface for electrically connecting to the IC card 5 inserted in the above-mentioned slot (not shown).

The IC card 5 has a built-in memory 5a as "storage means", and the memory 5a stores a serial number as "unique identification information". Therefore, the microcomputer 3 in the handset 15
1 can read the serial number from the IC card 5 connected to the card I / F unit 29.

The card presence / absence detection switch 28
Corresponds to "mounting detection means" and "removal detection means", IC
A switch for detecting whether or not the card 5 is mounted at a predetermined mounting position. If the IC card 5 is mounted at the predetermined mounting position, a relatively high voltage signal is required. For example, a relatively low voltage signal is output to the microcomputer 31. This I
The “predetermined mounting position” of the C card 5 is the card I / F unit 2
In relation to No. 9, it is determined as follows.

That is, the IC card 5 has an external connection terminal (not shown).
The electrical connection is made by contacting the terminal of the card I / F section 29 on the side. And I
When the C card 5 is inserted into the slot, when the C card 5 is inserted to some extent, the external connection terminal of the IC card 5 becomes the card I / F.
The position where the contact with the terminal of the part 29 is started, and the position is further inserted by a predetermined distance from the position is the above-mentioned “predetermined mounting position”. Accordingly, if the IC card 5 is moved within a predetermined distance even if the IC card 5 is moved to a direction in which the IC card 5 is at the predetermined mounting position and is removed from the predetermined mounting position, the card I
/ F section 29 can be electrically connected. This is mainly to prevent the destruction of data stored in the IC card 5. Details of this point will be described later.

Further, the microcomputer 31 comprises:
As shown in FIG. 3, the CPU corresponds to a “state switching unit”.
In addition to a well-known configuration including a ROM, a RAM, and the like (not shown) centering on 32, the present embodiment further includes the following two types of characteristic configurations roughly divided.

The first characteristic configuration is a comparator 33. The comparator 33 compares the voltage signal supplied from the card presence / absence detection switch 28 with a predetermined judgment value, and uses the comparison result as a level signal as a CP.
Output to U32. Specifically, when the IC card 5 is at a predetermined mounting position and a relatively high voltage signal is output from the card presence / absence detection switch 28, the comparator 3
Reference numeral 3 outputs a Hi level signal to the CPU 32. The Hi level signal from the comparator 33 is used as an interrupt request signal (IRQ), that is, the Lo level →
It is input to the CPU 32 only when it changes to the Hi level. In addition, instead of such an interrupt request signal, a relatively high voltage signal and a relatively low voltage signal from the card presence / absence detection switch 28 are used as normal level signals without passing through the comparator 33 to the I / O port of the CPU 32. Is input to

The second characteristic configuration is that the operation clock of the microcomputer 31 is made variable. This will be specifically described with reference to FIG. Outside the microcomputer 31, two oscillation elements 56a and 56b are provided as elements for generating an operation clock.
A clock of a frequency for normal operation (10 MHz in this embodiment) is generated by one of the oscillation elements 56a, and a clock of a lower frequency (32 KHz in this embodiment) than the above frequency is generated by the other oscillation element 56b. Is to occur. And the microcomputer 31
, Two oscillation circuits 58a and 58b for oscillating the oscillation elements 56a and 56b, respectively, and an oscillation circuit 58
a, 58b, and a selector 60 that operates one of the oscillator circuits 58a and 58b and outputs a clock obtained from the operating oscillation circuit as an operation clock. The selector 60 is controlled by the CPU 32. That is, the microcomputer 31 sets its own operation clock to 10M.
Hz and 32 KHz.

In the normal mode in which the normal operation is performed, the microcomputer 31 configured as described above operates the oscillating element 56a and the oscillating circuit 58a to operate based on the 10 MHz clock, and also gives a command to the power supply control circuit 75. Thus, the power supply voltage is supplied from the power supply circuit 70 to each part. When a predetermined condition described later is satisfied, the microcomputer 31 operates the oscillating element 56b and the oscillating circuit 58b to operate at a clock of 32 KHz, thereby entering a sleep mode with low power consumption. Immediately before entering the sleep mode, the microcomputer 31 gives a command to the power supply control circuit 75 to cut off unnecessary power supply from the power supply circuit 70 to each part.

Therefore, the telephone device body 1 is in the normal state when the microcomputer 31 is operating in the normal mode, and when the microcomputer 31 enters the sleep mode, the power consumption accompanying the operation of the microcomputer 31 is reduced and Since the power supply to unnecessary parts is cut off, the sleep state is reached, in which the power consumption is extremely low.

The storage unit 24 stores, for example, a message message transmitted from another telephone device in the answering machine function state, mail data received in the electronic mail function state, and the like. It stores the serial number read from the IC card 5 or the like.

Further, the microphone 41 and the speaker 43 for the handset call provided in the handset 15 and the handfree microphone 17 for the handfree call and the speaker 27 in the cradle 13 are respectively connected to the call control unit 25.
The microphone 41 and the speaker 43 in the handset 15 are connected to the voice control unit 21 via the call control unit 25 during a handset call, and the handfree microphone 1 is connected via the call control unit 25 during a handfree call.
7 and the speaker 27 are connected to the audio control unit 21.

In the car telephone apparatus of the present embodiment configured as described above, it is assumed that the IC card 5 is mounted on the telephone apparatus main body 1 (specifically, a slot (not shown) provided in the cradle 13) and used. I do. Then, when the serial number is read from the IC card 5, the telephone device main body 1 determines that the use is permitted and sets the normal operation. However, if the serial number cannot be read (including the case where the IC card 5 is not mounted, of course), the telephone device main body 1 is substantially disabled from being used.

As described above, users can use their own ICs.
By installing the card 5, the telephone device can be used. In other words, when the IC card 5 is not mounted, the telephone device 1 does not perform the same operation as when the card is mounted. Means that you may. Therefore, when the IC card 5 is mounted at the predetermined mounting position, the normal operation is enabled only when the IC card 5 is removed from the predetermined mounting position. In order to switch, the telephone apparatus main body 1 operates as follows.

FIG. 4 is a flowchart showing processing executed by the microcomputer 31 in the handset 15. When an ignition switch (not shown) of the vehicle is operated, the voltage from the battery BT is supplied to the microcomputer 31 via the power supply circuit 70, and the processing shown in FIG. 4 starts.

In the first step S110, a power supply process for a sleep state is performed. This is because the microcomputer 31 is directly supplied with power from the power supply circuit 70, but is supplied to other parts through the power supply control circuit 75, so that the microcomputer 31 controls the power supply control circuit 75. Then, the power is supplied only to the minimum part capable of detecting that the IC card 5 is mounted at the predetermined mounting position. Specifically, control is performed so that power is supplied only to the card presence / absence detection switch 28 other than the microcomputer 31.

Then, in S120, control is performed to set the clock mode to the Lo level. Specifically, the CPU 32 shown in FIG. 3 controls the selector 60 to operate the oscillating element 56b and the oscillating circuit 58b so that the
By operating with a clock of KHz, a sleep mode with low power consumption is entered.

Therefore, in the state where the telephone device main body 1 is operating in the sleep mode by the processing of S110 and S120, the power consumption accompanying the operation of the microcomputer 31 is reduced and the card presence / absence detection switch 2
Since the power supply to parts other than 8 is cut off, the power consumption is extremely low.

In S130, it is determined whether or not the comparator 33 shown in FIG. If there is an interrupt request signal (S13
0: YES) The process proceeds to S140, but if there is no interrupt request signal (S130: NO), the determination process of S130 is repeated. That is, as long as there is no interrupt request signal, the above-described sleep mode with low power consumption is maintained.

S14 to which there is an interrupt request signal to shift
At 0, control is performed to set the clock mode to Hi level. Specifically, the CPU 32 controls the selector 60 to operate the oscillation element 56a and the oscillation circuit 58a, thereby
It operates based on a clock of 0 MHz and enters a normal mode in which normal power consumption occurs.

Then, in S150, power is supplied to each part of the telephone device body 1. This is as a power supply process for the sleep state in S110 described above.
Since only the card presence detection switch 28 was supplied with power except for the microcomputer 31,
A command is given to the power supply control circuit 75 to supply power to other parts.

Then, at S160, the IC card 5
It is determined whether or not is mounted. This determination is made based on a signal input to the I / O port of the CPU 32 as a normal level signal from the card presence / absence detection switch 28 without passing through the comparator 33. Specifically, if a relatively high voltage signal is input, it is determined that the IC card 5 is mounted, and the process proceeds to the subsequent normal processing in S170. On the other hand, if a relatively low voltage signal is input,
It is determined that the IC card 5 is not mounted, and the flow shifts to S190. The processing content of this S190 will be described later.

Next, the normal processing in S170 will be described.
Various processes are executed in the normal process in S170, and various control processes for realizing functions as a general telephone device are as follows. That is, a calling process for transmitting a call signal for calling another telephone device to the telephone line network via the wireless device 3, and a ring tone from the speaker 27 when a call signal is transmitted from the base station. The receiving process to be generated, the connection process for connecting the telephone device main body 1 to the telephone network when the user inputs a command to connect the telephone device main body 1 to the telephone network due to the generation of a ring tone, and the calling by the calling process When the previous telephone device is connected to the telephone network and a call can be made with the telephone device of the called party, or when the telephone device main body 1 is connected to the telephone network by the connection process, a call is made. When a telephone call with the telephone device of the caller becomes possible, the user transmits an audio signal input from the microphone 41 of the handset 15 to the base station, or a telephone network (in other words, the caller side). Telephone device) At speech signal, it executes speech input and output processing or the like for also generating a sound from the speaker 43 of the handset 15.

Further, for example, a message message obtained when a ring tone pattern is set or an answering machine function is set or mail data obtained when an electronic mail function is set is stored in the storage unit 24. This process is also executed as the normal process (S170).

In the normal processing (S170), before the processing using the general telephone function described above,
The serial number is read from the mounted IC card 5.
Specifically, the serial number stored in the memory 5a in the IC card 5 is read out via the card I / F unit 29. Then, a predetermined process based on the read serial number is performed.

The predetermined processing is, for example, determining whether the read serial number is usable in the telephone apparatus main body 1, and if the use is not permitted,
This is displayed on the display unit 22 and the power is turned off after a predetermined period of time. If the serial number is different from the serial number read at the last use, the data stored at the last use is deleted. It is a process to do. Specifically, for example, if there is a so-called answering machine function, if there is a message message addressed to the previous user, it is deleted, or if there is an e-mail reception function, the mail data addressed to the previous user is deleted. If it is erased. Further, for example, it is possible to store a telephone number that the user wants to keep in the memory 5a of the IC card 5, read out the telephone number therefrom, and use it as a telephone directory function. In this case, since the telephone number read from the IC card 5 is temporarily stored in the storage unit 24 of the handset 15, it is not preferable that another person knows this data. Therefore, even in such a case, the read telephone number data is deleted. By performing these processes, it is possible to prevent highly-private data from being known to others, thereby ensuring data security. Note that these processes do not necessarily have to be performed in such a manner.

Then, in S180, the IC card 5
It is determined whether or not is mounted. This determination is exactly the same as the above-described processing of S160, and is performed based on a signal input from the card presence / absence detection switch 28 to the I / O port of the CPU 32 as a normal level signal without passing through the comparator 33. If a relatively high voltage signal is input, it is determined that the IC card 5 is mounted, and S
The normal processing at 170 is repeatedly executed. On the other hand, if a relatively low voltage signal is input, it is determined that the IC card 5 is not mounted, and the flow shifts to S190.

The transition to S190 means that the IC card 5 is not mounted (S160: NO or S160).
180: NO), in S190, power supply to unnecessary parts is stopped in the sleep state. This is a process that is exactly the reverse of the process in S150 described above. That is, in the power supply process for the sleep state in S110, power is supplied only to the card presence / absence detection switch 28 other than the microcomputer 31. Therefore, in S150, the power supply to each part of the telephone device main body 1 is performed. Supply was made. Therefore, S19
At 0, the microcomputer 31 gives a command to the power supply control circuit 75 to return to the sleep state again at S110, so that power is supplied only to the card presence / absence detection switch 28 except for the microcomputer 31, The power supply to is stopped.

Then, in S200, control is performed to set the clock mode to Lo level as in S120 described above. This content has been described in detail in S120 and will not be repeated here. In this way, the state is shifted to the state where the telephone device body 1 is operating in the sleep mode (S190, S200), and the process returns to S130. That is, the sleep mode is continued until the IC card 5 is mounted again and the interrupt request signal is generated.

In addition, at an arbitrary timing during which each of these processes is executed, for example, when the ignition key of the vehicle is turned off and the power supply from the battery BT is stopped, the present processing routine ends. As described above, power consumption is reduced by performing state switching corresponding to the attachment / removal of the IC card 5 to / from the telephone device main body 1, and power supply is performed in response to the attachment / removal of the IC card 5. Since the automatic control can be performed, the user does not need to operate the power switch, so that the operability is improved, and the power switch itself is not required in the telephone device main body 1, which contributes to simplification of the configuration.

Further, the terminals of the card I / F unit 29 are electrically connected by contact with the external connection terminals of the IC card 5, but when the IC card 5 is at a predetermined mounting position, it is needless to say that If it moves within a predetermined distance even if it moves in the direction in which it is pulled out of the predetermined mounting position, the external connection terminal of the IC card 5 and the terminal of the card I / F unit 29 remain in contact. On the other hand, when the IC card 5 moves in a direction in which the IC card 5 is removed from the predetermined mounting position, the card presence / absence detection switch 2
8, the telephone apparatus main body 1 switches to the sleep state as described in the flowchart of FIG. In this sleep state, the card I / F unit 29
Power supply to the IC card 5 is stopped.
The electrical connection between the C card 5 and the card I / F unit 29 is released. Therefore, it is effective in preventing data stored in the IC card 5 from being destroyed.

Although the embodiment has been described above, the present invention can be implemented in various modes as follows. In the above-described embodiment, in order to prevent substantially effective use when the IC card 5 is not mounted,
In the sleep state, power is supplied only to the card presence / absence detection switch 28 except for the microcomputer 31. However, if the IC card 5 is attached, all functions can be used, of course. On the other hand, even if the IC card 5 is not attached, only the restricted predetermined functions are permitted. Power may be supplied to a part related to the realization of the function. Of course, in this case, not only the interrupt request signal generated only by mounting the IC card 5 as shown in FIG. 4 may be used as a trigger, but also, for example, a power switch may be separately provided. Of course, the advantage that the interrupt request signal generated by mounting the IC card 5 as a trigger can automatically shift to normal processing is left as it is. In other words, if the use situation is inconvenient if the use is not permitted at all when there is no IC card 5, the concept is to cope by permitting the use of only the restricted functions as described above.

Although the "IC card serial number" is used as the unique identification information stored in the IC card 5, it may be, for example, a telephone number corresponding to the owner of the IC card 5. The point is that it is only necessary to be able to distinguish the users, so that any serial number, that is, no duplicate number exists.

In the above embodiment, the IC card 5 is used as an example of the "card". In the case of the IC card 5, the storage means is a memory 5a using an IC. More specifically, an IC card provided with a microprocessor and capable of writing to the IC memory 5a (in a narrow sense) and an IC as an integrated circuit It is divided into a memory card including only the memory 5a. A memory card may be used as long as the contents described in the above embodiment are only realized. However, if the IC card 5 having a microprocessor and capable of writing to the IC memory 5a (in a narrow sense), Has a special effect.

That is, the mail data stored in the storage unit 24 of the telephone device main body 1 is stored in the memory 5a of the IC card 5, and the newly created telephone number is also stored in the memory 5a by operating the operation unit 45. You can also add data to the phone book function. Further, the following processing can be executed. In the above embodiment, the serial number of the IC card 5 to which the telephone device main body 1 is attached is stored, and it is determined whether or not the IC card 5 has been replaced. When attached to 1,
If the IC card 5 receives the identification number (for example, the manufacturing number) of the telephone device main body 1 and stores it in the memory 5a, the history of the attached telephone device main body 1 can be known. By doing so, if it is known from the past mounting history that the telephone device has been mounted on the same telephone device body 1 as the previous one, it is presumed that the data in the memory 5a has not been altered. The predetermined operation may be performed without confirming the data content. on the other hand,
Telephone device body 1 that was different from the previous one
If it is determined that the data is loaded in the memory 5a, it is possible that the data in the memory 5a has been altered. Therefore, it is conceivable to perform a predetermined operation after confirming the data contents. .

A magnetic card or the like cannot be written, but can be realized if the identification information is stored in a storage means (in this case, a magnetic material such as a magnetic stripe), and can be used similarly. However, the I used in the above embodiment was
The C card 5 has a higher security function and a larger storage capacity than the magnetic card, and therefore has high versatility. That is,
If the purpose is to prevent data with a high degree of privateness, such as message messages and mail data, from being known to others, use an IC card 5 that has a low possibility of falsifying stored identification information. Is more appropriate.

Although the above embodiment has been described as an example implemented as a car telephone apparatus, the present invention is not limited to the car telephone apparatus, but is also a portable telephone apparatus (so-called portable telephone apparatus) which is a mobile telephone apparatus which is also wirelessly connected to a telephone line network. Phone or PHS),
