Description

Description: TECHNICAL FIELD The present invention relates to an IC card reader / writer device for exchanging information with an IC card, and particularly enables data transfer between different types of cards. is there.

[Conventional technology]

Here, the IC card is used in place of a conventional card with a magnetic stripe, and has a memory IC, a CPU, and other semiconductor chips built into the base of the card. In addition to being able to have a large-capacity storage capacity of one digit or more, it can be provided with an arbitrary arithmetic function. A conventional reader / writer device for exchanging information with such an IC card is shown in FIG. The device shown in FIG. 2 has a read / write circuit (hereinafter referred to as an R / W circuit) 2
The data is read from the IC card 1 or written into the IC card 1 by the communication control circuit 3
Data is exchanged with an external device such as a computer terminal via the.

By the way, recently, it has been considered to use the above IC card as a life card of a product, that is, a card that stores history data from the birth (start) to the disposal of the product. For example, the manufacturing date of a certain product in the factory, manufacturing N
It is used as a card that stores various data such as o, quality information and management information, and also stores various data such as usage status in the general social system after the product is shipped out of the factory.

[Problems to be solved by the invention]

However, when using an IC card as a life card for cars and industrial machines, for example, there is a robot, a welding machine, etc. in the factory, and because the environment is very bad because it is easily polluted by oil, dust, and water, It is extremely difficult to make the IC card in the factory and the IC card in the general social system outside the factory have the same structure and function. That is, as a card used in a general social system, there is a card with a magnetic stripe, an IC card conforming to the ISO standard, etc., but these have a contact structure with a thickness of 0.76 mm,
At present, it cannot be used in factories with poor environmental conditions. Therefore, in a factory, a non-contact type IC card that does not come into contact with contacts by electromagnetic coupling, optical coupling, radio wave method or the like is generally used. Even in the contact structure, the thickness of the card and the like are often different between those in the factory and those used in the social system outside the factory.

In such a situation, if the conventional reader / writer device has the configuration,
It is impossible to realize with a single IC card.

The present invention has been made in view of such a point, and can store various data at a manufacturing stage of a certain product and data such as a usage status after being shipped out of a factory in one IC card. It is an object of the present invention to provide an IC card reader / writer device that can easily realize a card system.

[Means for solving problems]

An IC card reader / writer device according to the present invention is provided with a plurality of reading / writing units for reading and writing data from and from different IC cards, and receiving the information from one IC card. The data processing circuit receives the information from the read / write unit, processes the information, and transfers the information to the read / write unit for an IC card of a different type from the one IC card.

[Action]

According to the present invention, a plurality of read / write units for reading and writing data to different types of IC cards respectively, and the information read from the read / write unit receiving the information from one IC card The data processing circuit that receives and processes the data and transfers it to the read / write unit for an IC card of a different type from the one IC card is used. Information is read or written from different types of cards by the same reader / writer device, and data of each card can be mutually transferred via a data processing circuit.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an IC card reader / writer device according to an embodiment of the present invention. In FIG. 1, reference numeral 1 is an IC card used in a social system, for example, conforming to the ISO standard,
7 is a non-contact type IC card used in the factory, 10 is a card that can store both IC cards 1 and 7 at the same time.
A reader / writer device for reading or writing 1,7 data. In this reader / writer device 10,
Reference numerals 6 are first and second R / W circuits for reading data from or writing data to the IC cards 1 and 7, respectively. The first R / W circuit 2 has a contact. The structure and the second R / W circuit 10 have a non-contact structure. Reference numerals 4,5 denote first and second data processing circuits provided corresponding to the first and second R / W circuits 2 and 6, respectively, which are external devices (not shown) such as a computer terminal. The data of each R / W circuit 2 and 6 is processed by the support from and the data is transferred to the other data processing circuit. Reference numeral 3 is a communication control circuit that interfaces with an external device.

 Next, the operation will be described.

For the IC card 7 used in the factory, various data in the factory can be read by the reader / writer device dedicated to the non-contact type card or the reader / writer device 10 of this embodiment shown in FIG.
For example, manufacturing date, manufacturing number, quality information, management information, etc. are written. Various data stored in such an IC card 7 is used as a contact type IC card used in a social system by using the reader / writer device 10 shown in FIG. 1 immediately before the product is shipped out of the factory. Data is transferred to 1. Then, the contact-type IC card 1 is further written with various data such as usage status.

Here, the data transmission / reception between both cards is performed as follows. Various data in the factory stored in the non-contact type card 7 are read by the second R / W circuit 6 and input to the second data processing circuit 5. Then, this data is transferred to the first data processing circuit 4, and the first R /
W circuit 2 writes to contact type IC card 1. Control of each of these circuits is performed by a control signal from an external device such as a computer terminal input via the communication control circuit 3, and data transfer reverse to the above, that is, a contact type IC
Of course, data transfer from the card 1 to the contactless IC card 7 is also possible.

In the device of this embodiment, different types of cards such as a non-contact type card and a contact type card can be simultaneously read and written by the same reader / writer device, and data transfer between both cards is possible. It is possible to easily realize a product life card system that was difficult to handle with one type of card. In addition, in this embodiment, a non-contact type IC used in the factory
The card 7 can be used as a card for a new product after transferring the data to the contact type IC card 1.
It enables very efficient operation. That is, the card 7 used in the factory is more expensive than the card 1 used in the social system due to its nature, but the required number thereof is much smaller.

In the above embodiment, different types of cards are described as non-contact type and contact type, but the present invention is, for example, a case of multiple contact type cards of different thickness and other three types. It can be similarly applied to the case where data is mutually transferred by the above cards, and the same effect as the above embodiment can be obtained.

[Effects of the Invention] As described above, according to the present invention, a plurality of read / write units for reading and writing data for different types of IC cards and information from one IC card are stored. Since the information processing circuit receives the information from the received read / write unit, processes it, and transfers it to the read / write unit for an IC card of a different type from the one IC card, Different types
ICs that can transfer data between IC cards and are used as life cards when implementing a life card system
The effect is that one card can be used.
