The present invention relates to a system in which a C card is connected to an external device, such as a public telephone, which provides a certain service by being connected to the IC card or uses the IC card as a memory.
従来このようなＩＣカードの結合は、いわゆるコネクタ

設けられ、ＩＣカードと外部装置双方の接点を機械的に
押し付けることによってその接触を保障１〜、電力の供
給や情報の送受を行なってきた。Conventionally, such IC cards have been connected using a so-called connector. That is, the connector is provided with contacts, and by mechanically pressing the contacts of both the IC card and the external device, the contact is guaranteed, and power is supplied and information is sent and received.

The connector is mechanically pressed (~), so there is a
It requires t and 5 degrees and is not easy to operate. Furthermore, the number of insertions and removals is limited, making it unsuitable for services that require frequent insertion and removal.

。As a non-contact power transmission means, for example, there is a method of emitting light energy from one device and converting it into electrical energy using a photovoltaic element such as a solar cell on the other hand to obtain the necessary power. For small and thin devices such as IC cards, the received power cannot be sufficiently accumulated.For example, when trying to store and rewrite information using a non-volatile memory such as a so-called Ell:FROM as a memory element. There are restrictions on the configuration of the IC card, such as a lack of power.

Furthermore, as another means of securing energy, there is a method of using a built-in battery, but the battery has a limited lifespan and needs to be replaced, and there is also a risk that the information in the IC card may be destroyed during replacement.
