Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an IC card reader/writer device that exchanges information with an IC card, and in particular enables data transfer between different types of cars. It is.

[Conventional technology]

Here, an IC card is used in place of a conventional card with a magnetic stripe, etc., and has a memory IC, CPU, and other semiconductor pieces built into the base of the card, and has a larger number of chips than a conventional card with a magnetic stripe. In addition to being able to have an order of magnitude greater storage capacity, it can also be provided with arbitrary arithmetic functions. And like this fi
A conventional reader/writer device for exchanging information with an IC card is shown in FIG. The device shown in FIG. 2 has a read/write circuit (hereinafter R/W).
(referred to as a circuit) 2 reads data from the IC card 1 or writes data to the IC card 1,
It also sends and receives data to and from external devices such as computer terminals via the communication control circuit 3.

By the way, recently it has become popular to use the above-mentioned IC card as a product life card, that is, a card that stores historical data from the product's birth (start) to disposal. It stores various data such as date of manufacture, magnetic quality information, and management information, as well as various data such as usage status in general social systems after the product is shipped outside the factory. There are some that can be used as cards.

[Problems to be solved by the inventionj] However, when using an IC card as a life card for cars and industrial equipment, for example, there are robots, welding ladders, etc. in the factory, and oil, It's hard.

Because the environment is very sensitive, such as being easily contaminated by water, it is extremely difficult to make the structure and function of IC cards in factories the same as those in general social systems outside factories. That is, cards used in general social systems include the above-mentioned cards with magnetic stripes, IC cards compliant with ISO standards, etc., but these have a thickness of 0.5 mm.
It is 76 m5 in size and has an open front structure, and currently cannot be used in factories with poor environmental conditions. Therefore, in general, non-contact IC cards are used in factories, where the contacts do not come into contact due to electromagnetic coupling, optical coupling, or radio waves. Even for cards with a contact structure, the thickness of the cards often differs between those inside the factory and those used in social systems outside the factory.

In such a situation, if the configuration of the conventional reader/writer device is used, all life cards for a certain product can be stored in one
This would be impossible to achieve with just one IC card.

This invention was made in view of the above points, and it is possible to store various data at the manufacturing stage of a certain product and data such as the usage status after it is shipped outside the factory in one IC card. It is an object of the present invention to provide an IC card reader/writer device that can easily implement a guard system.

Means for Solving Problem C] The 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 a certain type of IC card, and A plurality of data processing circuits are provided for processing data in each read/write section and transferring data to and from other processing circuits.

[Effect]

In this invention, for example, the same reader/writer device reads or writes information from 1,000 different types of cards, such as a contactless card and a contact card, and the data on each card is processed by a data processing circuit. It becomes possible to transfer data between each other.

(Example〕 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a block configuration diagram of a 1'C card reader/writer device according to an embodiment of the present invention.

, 7 at the same time, and reads or writes data on each card 1, 7. This reader/writer device IO reads data from IC cards 1 and 7 respectively for 2 and 6 years old, or
1st for writing data to C card 1゜7. Second F
The first R/W circuit 2 has a contact structure, and the second R/W circuit 10 has a non-contact structure. 4.5 are respectively the 1st. The first R//W circuit 2.6 is provided corresponding to the second R//W circuit 2.6. A second data processing circuit processes the data of each R/W circuit 2.6 with support from an external device 1 (not shown) such as a combiator terminal,
This is transferred to the other data processing circuit.

Further, 3 is a communication control circuit that performs an interface with an external device.

Next, the operation will be explained.

The IC card 7 used in the factory has a reader/writer device exclusively for contactless cards or the reader/writer device of this embodiment shown in FIG. Date, manufacturing date, quality information, management information, etc. are written. Various types of data stored in the IC card 7 are stored in a contact type IC card used in a social system using the reader/writer device 10 shown in FIG. 1 immediately before the product is shipped outside the factory. The data is transferred to the contact type IC card 1, and various data regarding the usage rate are subsequently written to the contact type IC card 1.

Here, data is transmitted and received between Oka cards as follows. Various in-factory data stored in the non-contact type car 1'7 are read by the second R/W circuit 6 and input to the second data processing circuit 5. This data is then transferred to the first data processing path 4, and the first R
/W circuit 2 writes to contact type IC node 1. Control of each of these circuits is performed by a control signal from an external device such as a computer terminal inputted via the communication control circuit 3, and data is transferred in the opposite manner to the above, that is, data is transferred from the contact type IC car V1 to the non-contact type IC car V1. Of course, data transfer to the contact type IC card 7 is also possible.

In the device of this embodiment, different types of cards, a contactless card and a contact card, can be simultaneously read and written by the same 5 reader/writer device, and data can be transferred between the two cards. It is now possible to easily implement a life card system for products that was previously difficult to support with one type of card. In addition, in this embodiment, a non-contact type I used in a factory is used.
After the data is transferred to the contact type IC card 1, the C card 7 can be used as a card for a new product, and extremely efficient operation is possible. That is, although the card 7 used in the factory is more effective than the card 1 used in the social system due to its nature, the number of cards 7 required is significantly smaller.

In addition, in the above embodiment, the case where there are two types of different cards, a non-contact type and a contact type, has been explained, but the present invention is also applicable to the case where there are a plurality of cards of the same type with different thicknesses, 'ζ can also be used in cases where data is transferred between cards of more than one type, and the same effects as in the above embodiment can be obtained.

〔Effect of the invention〕

As described above, according to the present invention, a plurality of reading/writing units are provided so that data can be read/written simultaneously to different types of IC cards, and furthermore, data can be transferred between the different types of cards. Since such a data processing circuit is provided, it is possible to easily implement a life card system for products, which was difficult to support with a single type of card in the past.
