DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a system equipped with a plurality of contact-type IC cards each having a microcomputer 2 semiconductor memory mounted on a card-like member. - It relates to an IC card processing system that allows data to be directly copied, written, and read between IC cards without using a writing device.

(Prior Art) Magnetic recording media such as floppy disks and cassette tapes have traditionally been widely used as external storage devices for computers and computer-based electronic equipment. In order to achieve this, RAM
, card-shaped or package-shaped recording media equipped with semiconductor memories such as ROM have been used. on the other hand,
In the fields of credit cards, ID cards, bank cards, etc., microprocessors and RAM are used in card-like components to replace magnetic cards.

2. Description of the Related Art In recent years, so-called IC cards have been developed which are equipped with electronic circuits including semiconductor memories such as ROMs. This IC
Cards are superior in capacity, functionality, confidentiality, reliability, etc. compared to magnetic cards, and therefore data processing systems using IC cards are expected to become widespread in the future.

Since data can be freely read and written to this IC card using a reading/writing device, data can be copied from one IC card to another. FIG. 4 is a block diagram showing an example of a conventional configuration for copying data. That is, as shown in FIG. 4, first, an IC card from which data is to be read (hereinafter referred to as a reading card) (CR) is loaded into the card loading section 31, and this reading card (CR) is loaded into the card loading section 31.
Data is read from the external computer 32 according to instructions. Next, the IC card (
A write-side card (Cw) (hereinafter referred to as a write-side card) is loaded into the card loading section 31, and the read data is written to the write-side card (Cw). In FIG. 4, reference numeral 33 indicates a reading card (CR) loaded into the card loading section 31 under the control of the external computer 32.
, a controller that accesses the writing side card (Cw). Further, 34 is a reading side card (CR) and a writing side card (CW) under the control of the controller 33.
This is a power/clock supply section that supplies power and clock to the card loading section 31 for accessing the card loading section 31. here,
By the controller 33 and the power supply/clock supply section 34,
It constitutes a reading/writing device.

Although the outline of conventional data copying is as described above, the processing procedure of the external computer 22 in this case is shown in FIG. A detailed explanation of FIG. 5 will be omitted, but the general outline will be as follows. That is, step 8
Steps 1 to S9 represent processing for reading data from the reading card (CR), and steps SIO to S16 represent processing for writing data to the writing card (Cv).

(Problems to be Solved by the Invention) However, in such a conventional data copying method, the first problem is that it takes a long time to copy data. That is,
For example, if the memory capacity of the IC card is 64 Kbit, there will be 960 bits of space between the external computer 32 and the controller 33.
Using the 08PS serial interface, the data format is set to 1 bit for the start bit and 8 bits for the data length.
When the pin and stop bits are 2 bits, the data transfer time between the external computer 32 and the controller 33 is (64X210/8) XI IX (1/96
00)=9. 39 [sec]. Since this is necessary twice, once when reading data and once when writing data, the time required to copy the data becomes as long as about 19 seconds.

In addition, in the conventional data copying method, the reading side card (
Since the data of CR') is developed on the data area of the external computer 32, there is a problem in terms of confidentiality.

Furthermore, since a dedicated reading/writing device is always required to perform data copying and writing/reading processing, the actual situation is that system construction is difficult due to issues of installation location and cost. be.
