Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a terminal device in which an IC card is mounted and read, and the read data is used, and particularly based on data update of the IC card. The present invention relates to an IC card terminal device capable of managing a revision of a data area.

(Prior Art) An IC card is one of portable recording media. This IC
The card is a card with a built-in semiconductor memory, CPU (microprocessor), etc.
By attaching it to a writer, you can read and write data stored in the built-in memory, execute built-in programs, etc., so it has been used in various fields such as bank cards, ID cards, credit cards, etc. .

Generally, an IC card is set in an IC card terminal device,
Communication is performed by connecting to a host computer at a center via a communication line to receive services. In addition, there is also a portable telephone directory memory card used by attaching to a telephone or the like.

A portable telephone directory memory card is a device in which the name of the other party and dial data are registered in advance, and when the portable telephone directory memory card is attached to the telephone, the registered contents of the IC card reader / writer of the telephone are registered. Is read out, and a list is displayed on the display unit of the telephone together with the reference number.For example, when a reference number of a target is input by using a dial key, the CPU of the telephone sets the corresponding dial data into the portable telephone directory memory card. Then, the data is read out as dial data, and a function of making a dial call based on the dial data as if the data was input by a dial key can be realized.

By the way, FIG. 4 shows a conventional example of an IC card telephone which reads the stored contents of the IC card when the IC card is mounted, writes the data in a built-in memory and uses the data. FIG. 1 is a block diagram showing a main part configuration.
Reference numeral 3 denotes an IC card telephone loading unit which reads stored contents in the IC card 1 when the IC card 1 is mounted, writes the data in a built-in memory and uses the data.

The IC card telephone loading section 3 has an IC card reader / writer device 4 for reading stored contents in the IC card 1 and supplying data to the IC card 1 for writing given data. This IC card reader / writer device 4
Is a reader unit 5 for reading and controlling the contents stored in the IC card 1, a detecting unit 6 for detecting when the IC card 1 is mounted on the IC card reader / writer device 4, and outputting a detection signal, and an IC card 1. And a writer unit 7 for controlling writing to write data into the memory.

The loading unit 3 has a CPU 8 and an IC
A memory 9 for storing data read from the card 1, holding other necessary data, storing a control program of the CPU 8, and a working area necessary for the CPU 8 to perform control. The reader unit 5, the detection unit 6, the writer unit 7, the CPU 8, and the memory 9 are connected by a data bus 10, which is a signal line for exchanging signals between the reader unit 5, the detection unit 6, the CPU 8, and the memory 9.

The operation of the conventional apparatus having such a configuration will be described with reference to the flowchart of FIG. First, when the IC card 1 is inserted into the IC card reader / writer device 4 of the loading unit 3 of the IC card telephone (st1), the detection unit 6 of the loading unit 3 detects that the IC card 1 has been inserted (st1).
2).

Then, the detection signal is transmitted through the data bus 10 to the CP.
Sent to U8. CPU8 receives this detection signal and IC card 1
The reader unit 5 reads the program in the IC card 1 and outputs it on the data bus 10.

Thus, the program in the IC card 1 is read (st3). The read program data is taken into the memory 9 via the data bus 10 under the control of the CPU 8 (st
4), end loading (reading) (st5).

As described above, when the IC card 1 is mounted on the IC card telephone, the IC card telephone immediately reads out the stored contents of the IC card 1 and stores it in the memory in the IC card telephone.

This kind of loading method is applied to a case where the data already loaded in the loading unit 4 of the IC card telephone is the same as the data in the IC card 1.
If a new mounting is performed, the loading is performed again. Therefore, each time the mounting is performed, the user waits until the loading is completed.

This loading time requires several tens of seconds to read all the data in the IC card 1 because the IC card 1 has a capacity of several kilobytes. Since other functions cannot be performed, the waiting time is extremely wasteful and extremely difficult for the user to use.

(Problems to be Solved by the Invention) As described above, in an IC card telephone, an IC card is
When attached to an IC card telephone, the IC card telephone immediately reads out the stored contents of the IC card and stores it in a memory in the IC card telephone.

Then, in this case, even if data of the same content has already been loaded in the memory of the IC card telephone, the operation is performed again. Therefore, for example, after a person attaches his or her IC card to an IC card phone and uses it,
If you take it out, leave your seat, and try to use your own IC card again after a while, even if the stored data in the phone is the same, read it again by installing the IC card Therefore, every time an IC card is used, the user has to wait a long time of several tens of seconds or more for loading.

In the meantime, since the IC card telephone cannot be used, the waiting time is extremely wasteful and extremely difficult for the user to use.

Therefore, an object of the present invention is to provide a mounted IC.
If the card is the same as the one used in the IC card phone last time, reading is not performed, and the previous reading data remaining in the memory in the phone is used as it is, and useless reading processing is performed. Accordingly, it is an object of the present invention to provide an IC card terminal device in which usability is drastically improved, for example, the terminal can be used immediately even if an IC card is inserted when there is no change in data.

[Configuration of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention is configured as follows. That is, an IC card terminal device comprising: an IC card; and a terminal device which reads information from the IC card when the IC card is inserted, stores the information in a built-in first storage means, and resides and uses data. In the above, the IC card has a second storage means capable of updating stored data, and the storage means is provided with revision code information including password data arbitrarily set by an individual, and when the data is changed. Second control means for updating the revision code information inside the IC card is provided, and when the IC card is mounted on the terminal device side, the revision code information including the password data in the IC card is read. And a control means for controlling to read information in the IC card only when there is a mismatch with the revision code information in the data held in the first storage means. .

(Operation) In such a configuration, when data is written to the IC card, the second control means of the IC card automatically outputs the revision code information for managing the data area in which the rewriting has occurred. On the other hand, while on the phone side IC
When the card is inserted, data is read from this IC card and read into the IC card read data holding area in the first storage means in the telephone, which corresponds to the data already read into the holding area before that. Revision code information (revision information) including personal identification data is read from the holding area, collated with the revision code information of the mounted IC card, and only when there is a mismatch, the data is read from the mounted IC card again, and the first storage is performed. The data is read into the IC card read data holding area in the means.

As described above, in the present device, since the data area in the IC card and the revision code information of the data area for holding the IC card read data in the memory of the IC card terminal are managed, the data area having the same revision code information is managed. When the data is the same, there is no reloading.

Therefore, even if a new IC card is inserted into the IC card terminal, the loading on the terminal side is not performed as long as the data does not change, so that the dead time for the loading can be eliminated, and therefore, the data is already loaded on the terminal side. If there is no difference from the data, the terminal can be used immediately even if the IC card is inserted, and an IC card terminal device with drastic improvement in usability can be provided.

Further, in the present invention, even if the contents of the revision code information other than the password data match, including the password data which can be arbitrarily set by the individual, the data is changed if the password data does not match, in the revision code information. Upon determination, the corresponding data is read from the IC card into the terminal device and updated. Therefore, when a plurality of users share a terminal device, even if the revision code information of the IC card used by each of the users coincides with each other, each user may use his / her own IC card.
By setting different password data on the card, the data in the terminal device can be updated.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the present apparatus.
1a is an IC card, 2 is a revision automatic addition circuit,
A circuit for automatically updating the revision number when writing control is performed and rewriting the revision number in the update target area of the data area of the IC card 1a, and is built in the IC card 1a.

The function of the automatic revision adding circuit 2 is an IC card.
The CPU of 1a may be provided. Reference numeral 3a denotes an IC card telephone loading unit. When the IC card 1a is mounted, the IC card telephone loading unit reads stored contents in the IC card 1a, writes the read contents into the built-in memory, and uses the data. It is.

The IC card telephone loading unit 3a has an IC card reader / writer device 4 for reading stored contents in the IC card 1a and supplying data to the IC card 1a for writing given data.

The IC card reader / writer device 4 is a reader unit 5 for reading and controlling the contents stored in the IC card 1a. When the IC card 1a is mounted on the IC card reader / writer device 4, it detects this and outputs a detection signal. And a writer unit 7 that controls writing to write data to the IC card 1a.

The loading section 3a is composed of a CPU 8 and an IC
A memory 9 for storing data read from the card 1a, holding other necessary data, storing a control program for the CPU 8, and a working area necessary for the CPU 8 to perform control. , Numeric keypad 11a for inputting numerical data, etc., and registration key 11b for registration operation
And a key input unit including

The reader unit 5, the detection unit 6, the writer unit 7, the CPU 8, the memory 9, the numeric keypad 11a and the registration key 11b are connected by a data bus 10, which is a signal line for exchanging signals with each other. .

The operation of the apparatus having such a configuration will be described with reference to the flowchart of FIG. FIG. 2 shows an example of loading telephone directory data from the IC card 1a to the IC card telephone. The IC card 1a has a built-in memory and CPU, and on the memory, a data area is provided in addition to a program area.

The data area is divided into various areas such as a telephone directory, a bankbook, and a credit, and an ADF (classification number) of the area is given to each area for each use.

Then, a revision number data column (revision code information column which is renewal information) next to the ADF in the data area.
, Where revision number data, which is update information updated every time the content is updated, is stored.

The revision number data includes area information and update data such as a number that is updated each time information is updated, in addition to personal identification data that can be arbitrarily input and set by an individual in advance.

By combining the password data with the area information and the update data, it is possible to manage the area so as not to be confused with the area number and the revision number data of the IC card of another person.

As shown in FIG. 2, in the case of telephone directory data,
Name and telephone number information can be stored in order, and in the program area, a list display function and an edit function of this telephone directory, specified information is extracted from the information displayed in the list, and based on that information Has a dial call designation function for passing dial data to a communication control unit of the telephone and automatically dialing.

Note that these functions provided to the program on the IC card side can be provided to the telephone side.

In this device, as shown in FIG. 2, an IC card is stored in a predetermined memory area in a memory 9 of the IC card telephone.
The data read from the 1a side is stored and retained in its entirety, the revision number information for each area is compared, and for areas where there is a mismatched revision number, control is performed to read the data in that area from the IC card side.
The control program of U8 is configured. Therefore, when the predetermined memory area in the memory 9 is initialized, the revision number information itself does not exist,
Since there is an area for storing the revision number information, the revision number information in this case is initialization data, for example, all zeros.

Naturally, when accessing an area in which important data is stored, collation of a personal identification code, collation of an ID code, and the like are performed.

Next, the operation of the present apparatus will be described. As shown in FIG. 3, first, the IC card 1a is inserted into the IC card reader / writer device 4 of the loading section 3a of the IC card telephone (st11). The detection unit 6 detects that the card 1a has been inserted (st12), and the detection unit 6
Send to

The CPU 8 receives this detection signal and reads the revision number added after each ADF (classification number) in the data area of the IC card 1a so as to read the respective revision numbers.
The reader unit 5 of the writer device 4 is controlled, whereby the reader unit 5 reads the revision number data in the IC card 1 and outputs the data on the data bus 10.

As a result, the revision number data for each application area in the IC card 1a is fetched into the temporary holding area of the memory 9, and the revision number data in the corresponding application area in each application area in the predetermined memory area of the memory 9 is stored. To match.

Then, as a result of the comparison, it is determined whether or not the data has already been loaded based on the match / mismatch of the revision number data (st13, st14).

If the revision number is the same as the revision number in the IC card 1a, reloading is not performed (st2
1, st22), only when there is a mismatch, read the entire area of the application area with the mismatched revision number.
U8 gives a command to the reader unit 5, whereby the CPU 8 transmits the data of the area in the attached IC card 1a to the reader unit 5.
Read through (st15, st16).

The read data is taken into the area corresponding to the area of the memory 9 by the CPU 8 via the data bus 10, and the loading is completed.

At this time, the revision number of the data taken into the memory 9 is the same as the revision number in the IC card 1a.

Next, a case where data in the IC card 1a is changed or added will be described. For example, when creating a telephone directory, operate the key input unit 11 to enter the edit mode, set the data area of the telephone directory by operating the key input unit 11, and then enter the telephone number of the other party by the key input unit 11. Set (st17 to st1
9).

After the setting, the operation of the registration key 11b in the key input unit 11 of the IC card telephone causes the CPU 8 to control the set data to be written in the corresponding area of the IC card 1a (st2).
0, st24). At this time, the IC card 1a
On the side, the revision number automatic addition circuit 2 in the IC card 1a
(Or CPU) updates the revision number added after the ADF (classification number) in the telephone directory area (st2
Five).

If the IC card is used for a single purpose such as a phone book only, the IC card will only be used if the revision numbers do not match.
Reload the entire contents of the card.

In addition, when there are a plurality of application-specific areas, the entire contents of the IC card may be reloaded when even one revision number does not match. However, only one type of revision number can be assigned to the IC card, and it can be used as the overall revision number, and if the two do not match, the entire contents of the IC card can be reloaded. Simplification can be achieved.

In this way, the data area revision management is automatically performed. When loading data, the revision number of the data read into the memory area of the IC card telephone is compared with the revision number of the IC card, and if there is no match. By performing the loading only in the case, it is possible to provide an IC card telephone in which unnecessary loading is not performed.

As described above, the present invention provides a revision number in an IC card, and when data (for example, telephone directory data) is written from an IC card telephone, the revision number of the data area (the telephone directory data area) A means for automatically updating the data, and a memory for reading and holding data of the attached IC card in the IC card telephone;
When the IC card is inserted, the revision number of the IC card is read, and the revision number data in the IC card read data holding area in the memory in the telephone is compared with the revision number data. And control means for controlling to perform reading.

When data is written to the IC card, the IC card automatically updates the revision number for managing the rewritten data area, while the IC card is mounted on the telephone side. Toru IC
The data is read from the card and read into the IC card read data holding area in the memory of the telephone. Before that, the revision number of the data already read into the holding area is read from the holding area, and the revision number of the attached IC card is read. The data is read again from the attached IC card only when the data does not match, and is read into the IC card read data holding area in the memory of the telephone.

As described above, since the present device manages the revision information of the data area in the IC card and the data area for holding the IC card read data in the memory of the IC card telephone, the data is in the data area of the same revision. Sometimes there is no reloading.

Therefore, even if an IC card is attached to or detached from an IC card telephone, loading is not performed unless the data changes, so that waste time can be eliminated and the IC is easy to use.
A card phone can be provided.

The present invention is not limited to the embodiments described above and shown in the drawings, and can be appropriately modified and implemented without departing from the scope of the invention. For example, in the above embodiments, a telephone will be described as an example. However, the present invention can be effectively applied to any terminal that once reads data from an IC card, makes the data resident in a memory, and uses the data resident in the memory.

For the revision, in addition to numbers, alphabetic characters, hiragana, katakana, codes, and, if possible, kanji and Greek characters may be used.

[Effects of the Invention] As described above, according to the present invention, the revision management of the data area of the IC card is automatically performed,
Before loading, check the revision number of the data read into the memory area of the IC card terminal device and the password data arbitrarily set by the IC card owner against the revision number and the password data of the IC card, and find a mismatch. In the case where the loaded IC card is the same as the one that was previously loaded and used in the IC card terminal device, it is not read and remains in the memory in the terminal device by loading only in the case of Since the previous read data is used as it is, unnecessary reading processing is not performed, and therefore, if there is no difference from the data already read in the terminal side, even if the IC card is attached to the terminal, the read of the terminal is immediately performed. It is possible to provide an IC card terminal device that achieves a drastic improvement in usability, such as being able to be used.
