(1985-12-6) [IC card market, 249-262, and ■ JP,56-109166,U. Hereinafter, the composition is explained using figures. The block diagram showing the example of 1 composition of the information card of the former [ Drawing / 2 ] and Drawing 3 are perspective views showing the example. An external device for 1 to perform read-out of information and writing in Drawing 2 and 2 are information cards, and are direct-current power supply ■ from external device 1 to information card 2. E is supplied, and person and output signal l101~I10 n is delivered and received between the external device 1 and information card 2. As shown in Drawings 2 and 3, while information card 2 has rectangle-like main part 3 of a card made from the plastic etc. and the main part 3 of a card is provided with the power supply and two or more contacted type terminals 4 for signals which are exposed to the surface, Electronic integrated circuit (henceforth IC) 5 is provided in the inside. IC5 has semiconductor memory 6 and microprocessor 7 which controls writing and read-out of the information on the memory 6. In this kind of information card 2, if it is inserted in external device 1, the terminal by the side of external device 1 is contacted, and terminal 4 by the side of card 2 will read the information stored in memory 6 through these terminal 4 grades with external device 1, or will write in the information by the side of external device 1 in memory 6. It is with the information card of the above-mentioned composition, carrying out only (the problem which an invention tends to solve), Since terminal 4 is outside exposed, the loose connection by the dirt of the terminal contact part, oxidization, corrosion, wear, etc., malfunction by leakage current, and destruction of IC5 according to static electricity or external voltage common start, and a problem is rash in reliability. Although a battery, Shedder, a loop antenna, etc. are built in main part 3 of a card and the information card of the non-contact form which sends out a signal from a loop antenna using a battery is also proposed, without exposing terminal 4 on the surface of main part 3 of a card, in order to remove this problem, Main part 3 of a card becomes thick by battery attachment, or problems, such as battery exchange, arise. Since the necessity of contacting terminal 4 by the side of card 2 and a terminal by the side of external device 1 is in a direction which inserts information card 2 in external device 1, it is restricted to a certain direction. When a direction was inserted accidentally, it had to insert from the right direction again, and it was disadvantageous-on use inconvenience.

(Means for solving a problem) in the information card which performs read-out or read-out, and the writing of information in order that the present invention may solve the above-mentioned problem . -- almost -- rectangle-like the main part of a card, The receiving medium which is symmetrically arranged to the center line of each neighborhood of this main part of a card, and receives electric power and a signal from the exterior by non-contact, The power supply circuit which transforms into the direct-current electric power for power supplies the electric power inputted through this receiving medium, The recovery circuit which restores to the signal inputted through the above-mentioned receiving medium, and the memory which memorizes information, The memory control circuit which controls operation of the above-mentioned memory based on the output of the above-mentioned recovery circuit, It has an optical medium of penetration light type of the above-mentioned main part of a card arranged mostly at the center, and is by what stored the optical modulation circuit which modulates the light from the outside by the optical medium by the output of the above-mentioned memory control circuit, and it makes penetrate in the above-mentioned main part of a card. (OPERATION) The present invention constituted an information card as mentioned above. Therefore, without receiving supply of electric power and a signal from the exterior, without receiving restriction in the path of insertion of the information card, and similarly an optical medium receiving restriction in the path of insertion, by making light from the outside modulate and penetrate, a receiving medium works so that an internal signal may be outputted. Thereby, a signal can be delivered and received by a non-power supply and non-contact, without receiving restriction in the path of insertion. Therefore, the above-mentioned problem is removable. (EXAMPLE) Drawing 1 is a configuration block figure of the path-of-insertion freestyle information card of the penetration luster information read-out method showing the example of the present invention.

It is changed into input signal Si that the signal in transmission medium X supplied to the information card 20 side is also in intermediary transmitting @ / electric signal transformation circuit 22, and memory control circuit 24 is given. After memory control circuit 24 specifies an address based on the information included in the input signal Si, for example, fortune-telling lump information, and comes out of information to memory 25, it outputs the write-in completion signal, and gives it to optical modulation circuit 26. Optical modulation circuit 26 modulates light OPT from light source 12, and supplies penetration light 0PTo of the Modulation Shun to lightwave signal recovery circuit 13. Then, lightwave signal recovery circuit 13 restores to penetration 0PTo, and sends out output signal S0. Here, main part 21 of a card of the optical medium by the side of information card 20 is while being mostly provided in a center, Since the receiving medium is symmetrically allocated to center lines X and Y of main part 21 of a card, Even if which direction, the sand straw upper and lower sides, right and left, and the back and front are made reverse and it inserts information card 20 in external device 10, Since a combined state with an optical medium, light source 12, and lightwave signal recovery circuit 13 and also the combined state of receiving medium 22, and an electric signal / transmission signal conversion circuit 11 are constant, the always above operations are attained. 5th [ The ] figure~figure 10 shows other examples of the present invention which further materialized Drawing 1.
