が必要とされていた。When such a conventional IC card has a built-in power source as a lithium battery, it is difficult to make the IC card smaller and thinner, and moreover, the lithium battery has a limited lifespan, which is inconvenient. In addition, when the power is supplied from the reader/writer, the power is supplied by contact between the IC card and the reader/writer through the connectors provided on each of the readers/writers, and the signal line is connected to the contact part of the power line. Because large currents flow through them, special consideration was required at the contact points.

ネルギを各部へ供給する太陽電池をその電源として内蔵
したものである。In order to solve the above-mentioned problems, the built-in power supply type IC card of the present invention has a built-in solar cell as its power source, which converts light energy into electrical energy and supplies this electrical energy to various parts.
ＩＣカードの電源は外部から与えられる光エネルギによ
シ非接触式に得られる。Power for the IC card is obtained in a contactless manner by externally applied optical energy.
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

１の各部へ電圧および電流を供給する太陽電池６とから
構成される。1 is an IC card with a built-in power supply (hereinafter abbreviated as an IC card) which is an embodiment of the present invention, and 2 is a reader/writer for transmitting and receiving signals to and from the IC card 1. As shown in FIG. This IC card 1
is an input/output section 3 that sends and receives signals to and from the input/output device 7 of the reader/writer 2, and a central processing section 4 that processes the signals.
and a memory 5 that stores the working procedure of the central processing unit 4 and temporarily stores the calculation data of the central processing unit 4.
and a solar cell 6 that converts light energy given from a light source 8 built into the reader/writer 2 into electrical energy and supplies voltage and current to each part of the IC card 1 described above.
とのような回路構成を有するＩＣカード１は、その使用
時に光源８を持つリーダ／ライタ２に挿入されることに
より、その光源８からＩＣカード１の太陽電池６へ光エ
ネルギが与えられてその電源が供給され作動することに

供給する。When the IC card 1 having the circuit configuration shown in FIG. Power will be supplied and it will start working. That is, the solar cell 6 to which this light energy is applied converts the light energy into electrical energy within itself, that is, converts the light energy into voltage and current, and transmits this power to the input/output section 3 and the central processing section 4. , is supplied to the memory 5.
そのため、ＩＣカード１はその電源を非接触式に得るこ

有するリチウム電池のように不便なことはない。As explained above, the built-in power supply type IC card according to the present invention has a built-in solar cell as its power source, so that it can obtain power in a non-contact manner. There is no need to give special consideration to this. However, since this solar cell can be manufactured thinner than conventional lithium batteries, it is still possible to manufacture solar cells with a built-in power source.
Since the C card can be made small and thin and can be used indefinitely, it is not inconvenient like conventional lithium batteries with a limited lifespan.
