Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a telephone device,
In particular, the present invention relates to a telephone device in which a card storing personal information is detachable.

[0002]

2. Description of the Related Art In recent years, telephone devices typified by portable telephones, PHSs, car telephones, and the like have become widespread for both young and old. Such a telephone device has an answering machine function that records a message from the other party in the built-in memory when there is a situation where you cannot answer the call when you receive a call, and a telephone number of the other party you call And the corresponding speed dial or registration are stored in advance in the built-in memory (hereinafter referred to as "phonebook data"), and when making a call, simply enter the speed dial or registered name or select with the select button, Many have a memory dial function for dialing the corresponding telephone number. Furthermore,
The ringing pattern of the ringtone can be selected from a plurality of patterns according to personal preference, or a pattern can be created by the user, and the pattern is stored in memory. There is also an increasing number of devices provided with a function for setting a sound pattern to be performed.

[0003]

As one form of such a telephone device, a telephone device with a card is being developed. For example, in the case of a telephone device equipped with a card, for example, in the case of a car telephone device, a card slot is provided in a handset, a card such as an IC card is inserted into the card slot, and personal information stored in the card is stored. It is like using. This card stores various personal information of the card owner (for example, telephone number, telephone directory data in the memory dial function, sound pattern in the sound pattern setting function, and the like). In such a telephone device with a card, a PIN (Personal Identity Number) which is a personal identification number before inserting the card and before using the telephone so that others cannot use the card for personal use without permission. Key, and the telephone device checks the entered PIN against the PIN stored in the card, and permits use of the card only when both match, which is important for maintaining security. It is.

According to such a telephone device with a card, for example, when a certain person has such a card, the card is inserted into his / her own mobile phone and used at one time. Can insert the card into a company-owned mobile phone and use it, so that data such as the phone number stored on the card can be shared by multiple mobile phones, and the phone number of your own mobile phone as in the past You do not need to remember the phone numbers of your and your company's mobile phone separately. Further, since the telephone directory data and the sound pattern created by the individual can be used immediately just by inserting the card, it is not necessary to individually create the telephone directory data and the sound pattern.

[0005] By the way, in such a telephone device, the power supply may be temporarily interrupted during the operation thereof. However, in consideration of convenience, if the power supply is interrupted for a short time, it is the same as the state before the power supply was interrupted. A configuration that operates as follows. In other words, if the data is reset each time after a short interruption, the data must be reset from the beginning, or if data is being created, the data must be recreated from the beginning. It is. Such an instantaneous interruption that can operate in the same manner as the state before the interruption of the power supply is referred to as an “instantaneous interruption of the power supply”. It should be noted that the time that can be called instantaneous interruption is not constant because it differs depending on the device to which the power is supplied, but it is usually, for example, at most about a few seconds.

However, it is the telephone apparatus itself that is configured to automatically return to the state before the instantaneous interruption even when the instantaneous interruption for a maximum of about 2 or 3 seconds occurs. In this case, the card is reset. In other words, since the state returns to the state where the PIN is not verified, the user cannot use the key as it is.
The so-called "manual PIN verification", that is, verification of N with the PIN stored in the card, must be executed. Although PIN collation is important in maintaining security, manual PIN collation every time an instantaneous interruption occurs is an improvement issue in terms of convenience improvement.

[0007] Even when the power switch is turned on in normal use instead of such an instantaneous interruption, the PIN must be input every time as described above. Although important for maintaining security, having to enter a PIN each time the same user uses it is still an improvement in terms of convenience. If the only purpose is to eliminate the troublesomeness without considering security, a flag is set on the card to set that PIN verification is not required. If the PIN input is to be omitted, the verification unnecessary flag is set. Should be set. However, a card set so as not to require PIN collation can be used by anyone because it is not necessary to input a PIN when using the card.

Therefore, especially for a user who does not need to consider security, it is sufficient to set the collation unnecessary so as to improve the convenience. However, actually, it is desirable to obtain both of them, that is, to use both. It is required to secure the security while eliminating the trouble of having to manually input the PIN every time, thereby improving the convenience.

[0009] Therefore, the present invention provides a PIN at the start of power supply.
It is an object of the present invention to provide a telephone device that can reduce user's time and effort in performing collation, improve user-friendliness, and ensure security.

[0010]

According to the first aspect of the present invention, there is provided a telephone apparatus in which a PIN, that is, a personal identification number is input from a main body input means while a card is mounted on the telephone apparatus main body. Upon input, the control means checks the entered PIN against the PIN stored on the card, and if the two match, permits the use of the card, and if the two do not match, prohibits the use of the card. I do.
Here, the use of the card means, for example, reading or writing of personal information stored in the card, or using a telephone number if the card stores a telephone number (in this case, , The telephone number is charged to the registrant). Also. If the results of the PIN verification do not match, there is a high possibility that the operator is a third party trying to use the card without the card owner's permission. For this reason, if such a third party is allowed to read and write the card, there is a possibility that personally important message messages stored on the card will be erased or phonebook data will be falsified, In order to prevent this, use of the card (reading or writing of personal information stored in the card) is prohibited. Also, if such a third party uses the telephone number stored on the card without permission, the card holder will be charged. The use of telephone numbers). In this way, PIN collation for ensuring security is performed.

However, it is troublesome if the user must input the PIN every time the power supply for operating the telephone device is started. However, if you do not execute the PIN verification itself,
The above security cannot be ensured.

Therefore, the telephone device of the present invention, as a result of PIN collation by the control means, receives the P
When the IN matches the PIN stored in the card, the matched PIN is stored in the PIN storage means, and when power supply is subsequently started, the control means stores the PIN in the PIN storage means. P using the PIN
The IN collation is automatically performed. Therefore, when an authorized user uses the same card continuously on the same device, the result of automatic PIN matching is "match", so that the user can use the card without inputting the PIN each time. And contribute to improved convenience. On the other hand, if a person who has illegally acquired another person's card attempts to use the card with a telephone device different from the one in which the card was used, the result of the automatic PIN verification is, of course, "unmatched."". Therefore, the card cannot be used as it is. In the case where the PIN is manually entered and collated, the PIN for another person's card is used.
They don't know themselves and eventually can't use the card. Thereby, security can be ensured.

[0013] The "when the power supply is started" includes, for example, a case where the user intentionally operates the power switch by himself / herself and a case where the power supply from the power supply side is temporarily stopped for some reason. Later, there is a case where it is not intended to resume. As an example of the latter, for example, "power interruption" can be considered. As described in claim 2, in consideration of this momentary interruption of power supply, when the power supply is restarted, it is conceivable that the power supply can be operated in the same state as before the momentary power interruption. That is, if the data is reset each time due to a short interruption, the data must be reset from the beginning, or if the data is being created, the data must be created again from the beginning. If it is possible to operate in the same state as before the momentary power interruption, such trouble is eliminated, but it is the telephone device itself that automatically returns to the state before the instantaneous interruption described above, and on the card side, Even if there is a momentary interruption, the state is reset and the state returns to the state where the PIN verification is not performed. Therefore, it cannot be used as it is, and cannot be used in the same manner as before the instantaneous interruption without the pin collation again. However, it is troublesome if a PIN must be manually input every time an instantaneous interruption occurs.

Therefore, as a result of the PIN collation by the control means, if the PIN input from the main body input means matches the PIN stored in the card, the matched P
The IN is stored in the PIN storage unit, and the control unit automatically executes the PIN verification using the PIN stored in the PIN storage unit when the power supply is restored after the instantaneous power interruption. As a result, the PIN verification itself for security is executed, but as long as the same card is used, the result of the PIN verification becomes “match”. Therefore, it is possible to use the PIN without inputting the PIN each time. And contribute to improved convenience.

It should be noted that PI at the time of power restoration after the momentary interruption of the power is
The N automatic verification may be performed in the same manner for all cards, but the execution target may be limited. That is, the users who can obtain the advantage of improvement in usability are limited. For example, the identification information unique to the card is also stored in the card, and when the power supply is restored after the instantaneous interruption of the power supply, first, the identification information unique to the card is read from the card, and the card having the specific identification information is read out. Only for PI
The automatic matching of N is executed. Therefore, the card having no specific identification information is subjected to the manual collation as before. That is, the user needs to input the PIN again.

By the way, the control means performs a predetermined process when the power supply is restored after an instantaneous interruption of the power supply. It is also assumed that the restored power supply voltage does not return to a level necessary for normal operation. You. Therefore, it may be determined whether or not the restored power supply voltage is at a level necessary for normal operation, and if the power supply voltage has not reached the required level, automatic PIN verification may not be performed.

This is because if the power supply voltage is at such a level that the telephone device main body cannot operate normally, the same operation as before the instantaneous interruption cannot be performed. Note that the unique identification information stored in the card may be, for example, a serial number of the card or a telephone number corresponding to the owner of the card. 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 described above, any information that can store personal information including PIN and unique identification information and that can be detachably attached to the main body of the telephone device can be used. 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,
Either 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.

The telephone apparatus of the present invention can be applied to various telephone apparatuses. In consideration of the above-mentioned "power supply interruption", a typical example is an automobile telephone apparatus. In other words, the power supply for operating the telephone
This is a case where the power is supplied from a battery mounted on the vehicle and supplying power to various parts of the vehicle. In this case, for example, power supply is usually prioritized for starting the engine, and during that period, it is considered that power interruption to other electric devices often occurs. Needless to say, a case in which a momentary power interruption occurs due to other causes is also assumed.

Of course, the present invention is not limited to a mobile telephone device, but also a mobile telephone device (so-called mobile telephone or PHS) which is a mobile telephone device which is also wirelessly connected to a telephone line network.
The same applies to a home telephone device, which is a fixed telephone device connected to a telephone network via a transmission line, as long as an instantaneous power interruption can occur. For example, in the case of a mobile phone device, a battery is built in as a power source. However, even when the battery is temporarily removed and then re-mounted, a power interruption may occur. In the case of an in-home telephone, a power adapter is often connected to an outlet of a commercial power supply, and if the power adapter is removed and reconnected, a momentary power interruption may occur.

The PIN is compared with the PIN stored in the card 5 and the collation result is OK, that is, P
When IN matches, normal operation can be executed,
If they do not match, normal operation cannot be performed.

Here, the normal operation refers to various control processes for realizing a function as a general telephone device, and examples thereof include the following processes. Call processing for transmitting a call signal for calling another telephone device to the telephone network via the wireless device 3 When a call signal is transmitted from the base station, the card 5 is transmitted from the speaker 27 of the cradle 13 to the card 5.

When the operation of updating the telephone directory data is performed, the updated contents are stored in the card 5 for the telephone directory data update processing. In a state where normal operation cannot be performed, the above-described function as a general telephone device cannot be used. Therefore, only auxiliary functions such as displaying the current time can be used.

Further, the present mobile telephone device 1 has a battery B
Even if an instantaneous interruption of the power supplied from T to the telephone device main body, that is, the wireless device 3, the cradle 13, and each unit in the handset 15 via the power supply circuit 60 in the wireless device 3 occurs, the power supply is thereafter performed. When restarted, it is assumed that it is configured to be operable in the same state as before the momentary power interruption. In other words, if the data is reset each time after a short interruption, the data must be reset from the beginning, or if data is being created, the data must be recreated from the beginning. It is.

However, it is the telephone apparatus itself that automatically returns to the state before the momentary interruption, and the card 5 is reset even if the momentary interruption occurs.
That is, since the state returns to the state where the PIN collation has not been performed, the terminal cannot be used as it is, and the same operation as before the instantaneous interruption, such as using the telephone directory data in the card 5, must be performed again after the pin collation processing is executed. Can not. However, it is troublesome if the user must input the PIN from the operation unit 45 every time a momentary interruption occurs.

Therefore, in the mobile telephone device 1 of the present embodiment, in such an instantaneous interruption, the PIN collation is automatically executed without the user inputting the PIN from the operation unit 45. If the power supply from the battery BT is started by operating the power switch 33 instead of such an instantaneous interruption, it is naturally necessary to perform PIN verification for security. Of course, when using for the first time, it is necessary to manually enter the PIN. However, even when the same user repeatedly uses the same card, the PI is required for each use.
If it is necessary to input N manually, it is troublesome.

Therefore, the mobile telephone device 1 of this embodiment is
In, when the user who used last time continues to use this time, the PIN collation is automatically executed without inputting the PIN from the operation unit 45. In the following description, paying particular attention to these points, the operation of the mobile telephone device 1 having the above configuration will be described.

FIG. 4 is a flowchart showing a process executed by the control unit 50 in the wireless device 3. This process is started when the power supply voltage supplied from the battery BT via the power supply circuit 60 and the power supply control circuit 65 exceeds a predetermined value. More specifically, the following two cases can be considered for starting this processing.

First, the power switch 33 provided in the handset 15 is turned on, and the control unit 50 controls the power control circuit 65 in response to the on operation, whereby power is supplied from the power control circuit 65 to each unit. Is executed. In other words, it is assumed that an ignition switch (not shown) of the vehicle is operated and power is supplied from the battery BT to the power supply circuit 60. In this state, the user operates the power switch 33 to turn on from the off state. In this state, power is supplied from the power control circuit 65 to each unit, and the control unit 50 determines that the supply voltage has exceeded a predetermined value, and starts this processing.

Another is a state in which power is not supplied from the power supply circuit 60 (or the supply voltage is low) even though the power switch 33 itself is operated to the ON side to allow power supply. The power supply circuit 6
This is the case where power supply from 0 is started or restarted.

In S110, which is the first step, it is determined whether or not the activation is made by the power switch 33. That is, it is determined whether or not the activation is caused by operating the power switch 33 from the off state to the on state. In the case of activation by the power switch 33 (S110:
YES), the process shifts to S150 without executing the processes of S120 to S140 described later. In S150, a signal indicating “normal startup” is transmitted to handset 15 via serial signal control unit 56. Then, S17
In step S180, the RTC generated by the RTC generation unit 58 is read and updated and stored in the backup RAM.
Then, a normal main process is executed. Thus RTC
At an arbitrary timing during execution of the normal main processing while updating and saving, for example, an ignition key of a vehicle (not shown) is turned off to stop the power supply from the battery BT, or the power switch 33 is turned off.
If the operation has been performed, this processing routine ends. If the power switch 33 is turned on while the power is supplied from the battery BT as described above, or if the power supply from the battery BT is restarted while the power switch is turned on, the processing of FIG. Starts again.

On the other hand, if the activation is not performed by the power switch 33 (S110: NO), the flow shifts to S120, where RT
The current RTC generated by the C generator 58 is read. The RTC read from the RTC generator 58 is referred to as RT
C (B). Then, in S130, the RTC stored in the backup RAM is read. The RTC read from the backup RAM is stored in the RTC (A)
Called.

In the following S140, RTC (B)-
It is determined whether the RTC (A) is less than 2 seconds. Where R
TC (B) -RTC (A) indicates the time during which the power supply was stopped. That is, since the main process is being executed while the RTC is being updated in the backup RAM in S170, the R read out in S130 is read.
TC (A) is the RTC immediately before the power supply is stopped, and RTC (B) read in S120 is the current RTC read from the RTC generation unit 58. Therefore, the difference [RTC (B) -RTC (A)] is the power supply stop time. “2 seconds” used as the criterion value is an example of the instantaneous interruption allowable time. The "permissible instantaneous interruption time" is the longest time for automatically returning to the state before the instantaneous power failure when the power supply voltage returns to normal within this time.

Therefore, an affirmative determination is made in S140,
That is, the power supply stop time is the predetermined instantaneous interruption allowable time 2
If the time is less than or equal to the second, the process proceeds to S160 because it is determined to be “power momentary interruption”. In S160, a signal indicating "there is an instantaneous interruption state and has been activated thereafter" is transmitted to the handset 15 via the serial signal control unit 56. After that, it moves to S170.

On the other hand, if a negative determination is made in S140, that is, if the power supply stop time is longer than the predetermined instantaneous interruption allowable time of 2 seconds, the flow shifts to S150, and as described above,
A signal indicating “normal startup” is transmitted to the handset 15 via the serial signal control unit 56.

As described above, in this embodiment, the wireless device 3 receives power supply from the battery BT3, and supplies power from the power supply control circuit 65 of the wireless device 3 to the power supply circuit 70 of the cradle 13. Therefore, the wireless device 3 determines whether or not the power supply is “instantaneously interrupted”,
The result is serially transmitted as "normal" or "momentary interruption".

Next, the processing executed by the control unit 31 in the handset 15 will be described with reference to the flowcharts of FIGS. In this process, when power is supplied from the power supply control circuit 65 of the wireless device 3 to the power supply circuit 70 in the cradle 13 via the power supply line LBT, and power is supplied from the power supply circuit 70 to the control unit 31, The process shown in FIG. 5 starts.

In S210, which is the first step, whether the control unit 31 has received the serial signal transmitted from the wireless device 3 via the serial signal line LS via the serial signal control unit 23 in the handset 15 is determined. Judge. If not received (S210: N
O), proceed to S220 and determine whether a timeout has occurred. For example, about 500 ms can be considered as the time for determining whether or not the timeout has occurred. And
If not a timeout (S220: NO), S230
Then, the process returns to S210 after making an inquiry about the serial signal to the wireless device 3 side. If a timeout has occurred (S220: YES), the present process is terminated.

On the other hand, if the serial signal from the wireless device 3 has been received (S210: YES), the flow shifts to S240 to detect the card 5, and then activates the card 5 in S250. The detection of the card 5 in S240 can be performed based on an output signal from a card detection sensor such as an optical sensor (not shown) provided in the slot when the card 5 is inserted into a slot (not shown), for example. The activation of the card 5 in S250 is a process of supplying power and an operation clock to the card 5 via the card I / F unit 29.

At S260, it is determined whether the content of the serial signal received from the wireless device 3 is "normal". If the content of the serial signal is "normal" (S26
0: YES), and proceeds to S270 to determine whether or not the card 5 is set to require no collation. The presence / absence of the setting that does not require collation is stored in the card 5 and is set in advance via an MMI (man-machine interface). Of course, there is no problem if the card 5 does not require the setting of the collation, but the determination in S270 is performed because the card 5 can be set without the collation. Then, if the collation unnecessary setting has not been made for the card 5 (S270: NO), S
The process proceeds to 280, and it is determined whether the automatic collation flag is “0” or “1”.

This automatic collation flag is changed in the mode setting process shown in FIG. 8, which is executed when the operation unit 45 is operated to set the mode while the telephone device 1 is running. be able to. The mode setting process of FIG. 8 will be described.

In the first step S710, a setting function is called. This can be instructed by the user operating the operation unit 45. Then, when the personal identification number is input in subsequent S720, in the next S730, P
A screen for selecting “whether” or “whether” the IN automatic collation is displayed on the display unit 22. The user looks at this display and performs an operation to instruct which mode to select. If there is an input for selecting this mode (S740: YES), the flow shifts to S750 to determine whether or not the result of the selection is a mode for performing automatic matching. If the result of the selection is a mode in which automatic collation is performed (S750: YES), the automatic collation flag is set to 1 (S760), and the present processing routine ends. On the other hand, if the mode is not the automatic collation mode (S750: NO), the automatic collation flag is set to 0 (S770), and the processing routine ends. In addition,
The automatic comparison flag (0 or 1) set in S760 or S770 is stored in the storage unit 24.

Returning to the description of the flowchart of FIG.
At 80, the automatic collation flag set as described above and stored in the storage unit 24 is determined. If the flag is 0, the process proceeds to S290 to perform manual PIN collation. On the other hand, if the flag is 1, the flow shifts to S300 to execute automatic PIN verification. Although these matching processes will be described later, when the matching processes (S290, S300) are completed, the process proceeds to S320. Note that if the collation unnecessary setting is not set for the card 5 (S270: YE
S), proceed to S320 as it is.

On the other hand, if a negative determination is made in S260, that is, if the content of the serial signal received from the wireless device 3 is not "normal", the flow shifts to S310, and the collation with the card 5 is unnecessary as in the process of S270 described above. Determine if the settings have been made. Then, if the card 5 has not been set to require no collation (S310: NO), the flow shifts to S300 to perform automatic PIN collation. On the other hand, if the collation unnecessary setting has been made (S310: YES), the process proceeds to S320.

Here, the respective matching processes in S290 and S300 will be described in order with reference to FIGS. First, the manual PIN collation processing in S290 will be described with reference to the flowchart in FIG.

This manual PIN matching process is a process of prompting the user to input a PIN and matching the input PIN with a PIN stored in the card 5. PIN
The contents prompting the input are displayed, and the system waits for the input of the PIN via the operation unit 45 (S520). When the PIN is input (S520: YES), the flow shifts to S530.
In S530, the input PIN is sent to the card 5, and an instruction is made to collate with the PIN stored in the memory 5a in the card 5. Then, in subsequent S540, the collation result is received from the card 5. When the collation result is received in S540, the present processing routine ends, the process returns to the process in FIG. 5, and the process proceeds to S320.

Next, the automatic PIN collation processing in S300 will be described with reference to the flowchart in FIG. This automatic PIN matching process is a process in which the user does not have to enter a PIN and the PIN is automatically matched. Therefore, in the first step S610, the registered PIN is registered.
Is read. The registration of the PIN will be described later in detail, but if the collation result is OK in either the manual collation or the automatic collation, the PIN itself that has become OK is registered in the storage unit 24 ( S30 in FIG.
5). Therefore, in this S610, the registered PIN is read.

After reading the PIN, the process goes to S62.
Then, the process goes to 0 and sends the read PIN to the card 5 to instruct the card 5 to collate with the PIN stored in the memory 5a in the card 5. Then, in subsequent S630, the collation result is received from the card 5. When the collation result is received in S630, the present processing routine ends, the process returns to the process in FIG. 5, and the process proceeds to S320.

Returning to the description of FIG. 5, in S320, it is determined whether or not the collation result obtained from the card 5 in S540 in FIG. 6 or S630 in FIG. 7 is OK (that is, the PIN matches). If the collation result is OK (S320: YES), the process proceeds to S330, and the PIN itself for which the collation result is OK is registered in the storage unit 24.
Then, in S340, the main process is started in the card use permission mode, and the process proceeds to the main process. When the main processing is executed in the card use permission mode, normal operation can be performed by freely reading data stored in the memory 5a in the card 5. Since the contents of the normal operation have already been described, they will not be repeated here.

On the other hand, if the collation result is not OK (S32
0: NO), that is, if the two PINs to be collated do not match, the process proceeds to S350, activates the main process in the card use prohibition mode, and proceeds to the main process. When the main processing is executed in the card use prohibition mode, reading of data stored in the memory 5a in the card 5 is prohibited, and only a very restricted operation can be performed. Regarding this restricted operation, it has been described that the function as the general telephone device described above cannot be used, and only auxiliary functions such as displaying the current time can be used. Part 22
In addition, a message notifying that the PIN cannot be used because the PIN does not match may be displayed. Further, the function may not be used at all.

When the process shifts to the main process as described above, the cradle 1 is transmitted from the power supply control circuit 65 of the wireless device 3 at an arbitrary timing when the process is executed.
When the power supply to the third power supply circuit 70 is stopped, the main processing itself ends. This power supply stop occurs in the following cases. First, an ignition switch (not shown) is turned off, and the power supply circuit 60 of the wireless device 3 is disconnected from the battery BT.
This is a case where the power supply itself to the power supply is stopped. Although the power supply itself from the battery BT to the power supply circuit 60 of the wireless device 3 is continued, when the power switch 33 provided on the handset 15 is turned off, the wireless device 3 is turned off.
This also occurs when the control unit 50 stops power supply from the power supply control circuit 65.

As described above, the mobile telephone device 1 of the present embodiment
, The PI input by the user via the operation unit 45
PIN that matches N with the PIN stored in card 5
If the collation result obtained by the manual collation (S290 in FIG. 5) is OK (S320: YES), the PIN
Is registered in the storage unit 24. Then, when the power supply is started by operating the power switch 33 at the next use, or when the power supply is restored after the instantaneous interruption of the power supply, the serial signal from the wireless device 3 is not normal and is “instantaneously interrupted”. Since there is (S260 in FIG. 5: NO), the storage unit 24
PIN automatic verification using PIN registered in
S280) is performed.

Therefore, an authorized user can use the same card 5
To use the same telephone device 1 continuously,
The result of the automatic matching of
It can be used without inputting N, contributing to improved convenience. On the other hand, if a person who has illegally acquired another person's card 5 attempts to use the card with a telephone device 1 different from the one in which the card has been used, naturally, the automatic PIN verification will be terminated. "Unmatched" (S30
0, S320). Therefore, the card 5 cannot be used as it is. Also, “PIN” shown in S290 of FIG.
Even when performing “manual collation”, the user himself / herself needs to input the PIN, and if the user does not know the PIN itself for the card 5 of another person, the card cannot be used after all. Thereby, security can be ensured. That is, it is possible to improve convenience and ensure security at the same time.

Further, even when an instantaneous interruption occurs, there is no need for the user to input a PIN each time the power is restored, and the usability is improved. In other words, the mobile telephone device 1 uses the power supply circuit 60 in the wireless device 3 from the battery BT.
Even if a momentary interruption of the power supplied to the telephone device main body, that is, the radio unit 3, the cradle 13, and each unit in the handset 15 via the power supply occurs, if the power supply is resumed thereafter, It can operate in the same state as. However, the card 5 is reset even if the momentary interruption occurs, and the same operation as before the momentary interruption such as using the telephone directory data in the card 5 is required until the pin collation processing is executed again, for example. Can not. It is troublesome if the user has to input the PIN from the operation unit 45 every time the instantaneous interruption occurs, but as described above,
In the case of an instantaneous interruption, the PIN is automatically checked without the user inputting the PIN from the operation unit 45, so that the usability is improved.

In the present embodiment, it is assumed that “collation-free setting” can be performed on the card 5 and FIG.
In S270 and S310, the presence or absence of the setting was determined. However, if only the card 5 for which such collation unnecessary setting cannot be performed is targeted, S270 and S3
The processing of 10 becomes unnecessary. Even if such a collation unnecessary setting cannot be made, the regular user does not need to manually enter the PIN as long as the authorized user repeatedly uses the same telephone device 1, so that the conventional collation unnecessary. You get the same benefits as if you could set it up. In other words, by adopting the present invention, there is no disadvantage in terms of convenience even for only the card 5 for which the collation unnecessary setting cannot be performed, and on the contrary, the merit of ensuring the security can be obtained again, and the effectiveness of the present invention can be obtained. Can be heard.

Although the embodiment has been described above, various embodiments are possible as follows. (1) In the above embodiment, when the power is restored after a momentary power interruption (FIG. 5
("NO" in S260) PIN automatic matching (S300)
Is executed on all the cards 5 in the same manner, but the execution target may be limited. In other words, the number of users who can obtain the advantage of improved usability is limited. For example, the card-specific identification information is also stored in the memory 5a in the card 5, and when the power supply is restored after the momentary power interruption, first, the card-specific identification information is read from the card 5 and the specific identification information is read. P only for card 5
The automatic matching of IN is executed. Therefore, for the card 5 having no specific identification information, the manual collation is executed.

(2) As the PIN, for example, a user may use an arbitrary number registered in the card 5 in advance, or use the unique identification information itself stored in the card as the PIN. May be. The identification information unique to the card may be, for example, a serial number of the card or a telephone number corresponding to the owner of the card. The point is that in principle, the number should only be known to the user.

(3) In the above embodiment, the card 5
Although the C card is used, for example, a magnetic card or the like may be used, or a memory unit having a memory function substantially equivalent to that of the card 5 may be used. However, an IC card generally has a higher security function and a larger storage capacity than a magnetic card, and therefore has high versatility. Therefore, it is more appropriate for practicing the present invention.

(4) In the above embodiment, the handset 15 to which the card 5 is attached does not directly judge whether or not the power supply is momentarily interrupted. Was to be notified. However, the present invention is not limited to such an embodiment. For example, the handset 15 itself may determine whether there is an instantaneous power interruption.

For example, the handset 15 is provided with an RTC generator 58 as provided in the wireless device 3 and the controller 31
It monitors the power supply voltage supplied from the power supply circuit 70 itself. Specifically, the time from when the voltage falls below a predetermined voltage level at which the device can operate to when the voltage again becomes equal to or higher than the predetermined voltage level is calculated based on the RTC. It can be determined by whether it is within.

(5) The above embodiment has been described with reference to an example in which the present invention is implemented as an automobile telephone device. This is because if the power for operating the telephone device is supplied from the battery BT mounted on the vehicle and supplying power to each part of the vehicle, the power supply for the engine is started during the period in which the power supply is prioritized. This is because it is considered that a momentary power interruption to the electric device often occurs. Needless to say, a case in which a momentary power interruption occurs due to other causes is also assumed.

Further, the present invention is not limited to an automobile telephone apparatus, but also a mobile telephone apparatus (so-called mobile telephone or PHS) which is a mobile telephone apparatus which is also wirelessly connected to a telephone line network,
The same applies to a home telephone device, which is a fixed telephone device connected to a telephone line network via a transmission line, as long as an instantaneous power interruption can occur. For example, in the case of a mobile phone device, a battery is built in as a power source. However, even when the battery is temporarily removed and then re-mounted, a power interruption may occur. In the case of an in-home telephone, a power adapter is often connected to an outlet of a commercial power supply, and if the power adapter is removed and reconnected, a momentary power interruption may occur.
