BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC card application device that uses an IC card to implement desired functions.

0002

[Prior Art] In recent years, large-capacity IC cards have been used in processor-applied equipment in which a CPU (processor) executes control and various arithmetic processing based on a program to obtain desired functions.
With the advent of memory cards, programs for various applications can be stored in IC cards, and when a desired application is used, the IC card for the application to be used is inserted into the application equipment, and this A system has appeared in which a program stored in an IC card is read into the memory of the application device and executed.

In this case, the basic program of the application device is stored in the device, a part of the application program is stored in an IC card, and when the IC card is attached to the device, the IC card is transferred from the device. - By reading the program stored in the card, storing it in the device, and executing it, one device can be provided with different functions by replacing the IC card.

By the way, in such processor application equipment (hereinafter referred to as IC card equipment), when an IC card is inserted into the equipment, the IC card equipment first reads the program stored in the IC card. It performs the following operations: reads the program, writes it to its own memory, and then executes the program placed in its own memory. Therefore,
It takes time to read a program stored on an IC card, and even when an IC card containing the same program is used repeatedly, it takes time from inserting the IC card to starting the service. Therefore, there is a problem of poor operability.

[0005]

[Problems to be Solved by the Invention] As mentioned above, IC cards
For card devices, when the IC card is inserted into the device, the IC
A card device first reads a program stored in an IC card, writes it into its own memory, and then executes the program placed on its own memory. Therefore, in the above device, when the IC card is reinstalled into the device, the process starts by reading the program on the IC card, so the
Even if you reinstall the C card, you will have to start by reading the program on the IC card, so especially if the system is configured to eject the IC card when the work is finished, the IC card with the same content will be replaced. There is a drawback that when the card is used repeatedly, it takes time from inserting the IC card to starting the service.

[0006] Therefore, an object of the present invention is to provide an IC card application device that can shorten the service start time when an IC card storing the same program is reinstalled. It's about doing.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention is constructed as follows. In other words, the IC card is configured to be removable, and the program read from the inserted IC card is transferred to the internal memory, and then the program on the memory is executed by the CPU. - In an IC card application device that can realize the necessary functions by replacing the card, information on the type of program stored in each IC card is added to the IC card application device. The program read from the IC card and its type information are held in the memory, and when the IC card is replaced, the type information is read from the IC card and compared with the type information on the memory to match. When this happens, the program is not read from the IC card, and when there is a mismatch, the program and type information are read from the IC card, and then the program in memory is executed. Configure.

[0008]

[Operation] In such a configuration, the IC card is configured to be removable, and the program read from the installed IC card is transferred to the internal memory, and then the program on the memory is transferred to the CPU. By running it, you can realize the necessary functions by replacing the IC card, but
Type information of the stored program is added to each IC card, and the IC card application device retains the program read from the IC card and its type information in the memory, and also stores the program read from the IC card and its type information. When replacing the IC card, the type information is read from the IC card, and when it is compared with the type information on the memory, the program is not read from the IC card. It reads the program and type information from the host, and then starts executing the program in memory.

[0009] In this way, in this device, a type function is assigned to the device program stored in the IC card, and a function for checking this is provided on the device side. When an IC card is inserted or removed, the device first checks the program type symbol, and if they are the same, it skips reading the program and operates with the program already stored in the device. Therefore, when IC cards with the same contents are inserted, the time required from the insertion operation to the start of service can be shortened. Also, if the program type symbol of the IC card checked when the IC card is inserted is different from the previous one, the program type symbol and IC card program stored in the device will be rewritten. You can get the desired functionality without any problems.

Therefore, according to the present invention, if the IC card storing the same program is reinstalled, the service
It is possible to provide an IC card application device that can shorten the time required to start a service.
