Abstract: An IC card adapter is connectable to an electronic device such as a computer or printer. The adapter removably stores a plurality of IC cards which are connected to the electronic device through a connector portion. The adapter has a housing with three slots each having a card receptor portion. A first slot on the rear side of the housing is larger than the other two slots on opposed sides of the housing. This first slot and card receptor portion are located closer to the bottom of the housing than the other two slots and card receptor portions. Indicators and a phone connection device can also be provided on the housing and a printed circuit board with electronic mechanisms can be provided within the housing so that the adapter can operate without the IC cards.

Abstract: An IC card adapter to be connected to an electronic device such as electronic computers includes an IC card receptor portion for removably storing a plurality of IC cards, a connector portion to be connected to the electronic device and a device for selectively connecting one or more of the IC cards to the computer.

Abstract: An integrated circuit card for use in an electronic arrangement when inserted into a receiving slot of the arrangement includes a card body having a flat and rectangular shape, a printed circuit board mounted on the card body, and an integrated circuit chip carried on the circuit board. The circuit board has a plurality of rows of connecting terminals which are arranged along an edge of the rectangular shape of the card body for establishing electrical connections with mating connecting terminals of a receiving slot of the electronic arrangement into which slot the card is inserted. The circuit board also has connecting wires printed thereon for electrically connecting circuitry of the chip with the rows of connecting terminals.

Abstract: In an IC card and electronic equipment using an IC card inserted in its connector slot, a specially-shaped member is provided relatively at both the IC card and the card insertion connector on the electronic equipment. The member allows the IC card to be inserted into the insertion end on the insertion connector only when the IC card is inserted into the card slot in the correct direction with the correct face orientation with respect to the card insertion connector. The member stops the card from being inserted into the connector slot so that the card edge does not reach the terminals on the connector if the card is inserted in the opposite direction or with the card face oriented incorrectly.

Abstract: An IC card having a built-in IC chip within its thickness includes a window for exposing the IC chip to ultraviolet rays. The window has ultravoilet-ray-permeable material placed in a position corresponding to the built-in chip on the surface of the card. The ultraviolet-ray-permeable material placed over the window protects the built-in IC chip from contamination due to dirt, and also from damage due to contact with objects external to the card.
