Integrated circuit card having memory errasable with ultraviolet ray

Claim 1

An integrated circuit card for use in an electronic arrangement, said card being capable of being received in a slot of said electronic arrangement, said slot having a plurality of mating connection terminals therein, said integrated circuit card comprising: a card body having a flat rectangular shape and a first and second primary surface, said first primary surface having a recess formed therein; a printed circuit board being mounted in said recess of said card body, said circuit board having a first and second side, said circuit board being mounted in said recess in a manner to permit said first side of said printed circuit board to form a flat, continuous surface with the first primary surface of said card body; an integrated circuit chip being carried on the second side of said printed circuit board and including a memory capable of storing information which can be erased by ultraviolet rays irradiated thereupon, said chip being adhered to said circuit board and encapsulation by a molding adhesive; a window being formed in the second primary surface of said card body to communicate with said recess, said window being located adjacent to the printed circuit board when said board is mounted in said recess of said card body, said window being smaller in size than said recess, and having an edge tapered in the direction from the second side of said circuit board to the second primary surface of said card body; a plate for covering said window, said plate being made from material which is permeable to ultraviolet rays, said plate being positioned in said window to permit ultraviolet rays to pass through the window and to reach the integrated circuit chip to thereby erase any information stored in said memory of the integrated circuit chip; a frame having an outer edge tapered to mate with the tapered edge of said window for carrying said plate; a plurality of connection terminals extending along an edge of the first primary surface of the card body, said plurality of connection terminals establishing electrical connections with said plurality of mating connection terminals of said electronic arrangement when said card is received in said slot; and a plurality of connection wires being mounted on the second side of said printed circuit board, each said connection terminal having a connection wire extending therefrom to the integrated circuit chip through throughholes formed in the printed circuit board, said plurality of connection wires serving to connect said integrated circuit chip with the connection terminals.
