Description

Detailed Description of the Invention 8. Detailed Description of the Invention [Field of Industrial Application] This invention relates to an IC card, and particularly to the shape and arrangement of a light-emitting element, a light-receiving element, and a solar cell.

Display on 1. Since the IC card tel having the above-mentioned characteristic sound has a rectangular shape as shown in FIG. 4, it is used by being removably inserted and fixed in the position shown in FIG.

[Problem that the invention seeks to solve]

Conventional IC cards have the shape shown in Figure 4, so if the IC card is installed incorrectly, it becomes impossible to read or write, and the position must be corrected, and the IC card must be inserted into the cassette. There were problems such as the need for a special automatic conveyance machine to attach the pocket for this part.

This invention was made to solve all of the above problems, and it allows signals to be sent and received no matter what position the IC card is placed in the cassette, and it can be transported using an automatic transport machine similar to the QUEHA. The purpose is to obtain an IC card.

[Means for solving problems]

The IC card according to the present invention has a disk-shaped substrate similar to a semiconductor wafer, and an optical signal transmitter, an optical signal receiver, and a solar cell are arranged concentrically with respect to the center of the disk-shaped IC' card. This is what I did.

[Effect]

The IC card according to the present invention has a disc shape similar to that of the QUAHA, and an optical signal transmitting/receiving section and a solar cell are disposed concentrically with the center of the disc of the IC card. No displacement of the input/output section of the reading/writing device occurs.

〔Example〕

An embodiment of the present invention shown in FIG. 1 will be described below.

In the figure, reference numeral 111 denotes an optical signal transmitting unit (2

This is the built-in IC card body.

The figures will be explained below. 1lol H Kueha Kasenoto, uli Kueha, 1j2) H Kueha Kasesoto +
The IC card 15+ is provided at the end of the card 101 at a portion where the IC card 15+ is inserted, and this entire portion is a window through which optical energy and optical signals can be received between the XC card reading and writing device.

When all the IC cards (5) are inserted into the Quahar cassette (!0), the IC card 161 has a circular shape,
In addition, since the optical signal transmitter 111, the optical signal receiver (2), and the solar cell (31) are arranged concentrically with respect to the center, no matter how the IC card (6) is inserted in any orientation, the optical signal will not be transmitted. Since the positions of section H1, optical signal receiving section (2), and solar cell (31) remain the same, the optical signal transmitting/receiving section of the IC card reading/writing device (not shown) and the section that emits light energy are integrated into IC.
If the configuration corresponds to the arrangement of the optical signal transmitting section II+, optical signal receiving section, and solar cell (3) of the card (6), and that these match, then the IC card ~ 61 and the IC card reading/writing device and O information exchange is possible.

Furthermore, since it has the same shape as the Quahar 1111, no special equipment is required for attachment and detachment.

〔Effect of the invention〕

As described above, in the IC card according to the present invention, the substrate is circular with the same dimensions as the semiconductor wafer, and the optical signal transmitter, the optical signal receiver, and the solar cell are arranged concentrically with respect to the center of the circular IC card. Because of this arrangement, it is easy to attach and remove the IC card to the Quahar cassette, etc., and it has the advantage of being able to be transported by an automatic transport machine similar to the Quahar cassette.
