Abstract

Abstract An IC card having an integrated circuit sealed within which includes a case constructed of a card-shaped synthetic resin material and internally incorporating an integrated circuit board. The case has a recess defined in one end thereof and opposite surfaces. A connector portion is disposed on the recessed end of the case and has contact pins positioned within the recess for connecting the integrated circuit board to an external circuit. A reinforcing metal plate covers each of the opposite surfaces of the case, with each metal plate having an integral end portion bent into an L-shaped configuration toward an inlet region of the recess and covering relation to a portion of the connector portion around the inlet region of the recess. The integrated circuit board has a ground-connection point electrically connected to the reinforcing metal plates.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 123 words
An IC card having an integrated circuit sealed within, comprising: a case constructed of a card-shaped synthetic resin material and internally incorporating an integrated circuit board, said case having end faces, side faces and upper and lower surfaces; a connector portion provided on one of said end faces of said case for connecting said integrated circuit board to an external circuit; a reinforcing metal plate covering each of said upper and lower surfaces of said case; each of said metal plates having an integral end portion bent into an L-shaped configuration to cover the peripheral portion of said one end face proximate said connector portion; and means electrically connecting a ground-connection point of said semiconductor integrated circuit to both of said metal plates.
Claim 2
Dependent Claim 123 words
An IC card having an integrated circuit sealed within, comprising: a case constructed of a card-shaped synthetic resin material and internally incorporating an integrated circuit board, said case having end faces, side faces and upper and lower surfaces; a connector portion provided on one of said end faces of said case for connecting said integrated circuit board to an external circuit; a reinforcing metal plate covering each of said upper and lower surfaces of said case; each of said metal plates having an integral end portion bent into an L-shaped configuration to cover the peripheral portion of said one end face proximate said connector portion; and means electrically connecting a ground-connection point of said semiconductor integrated circuit to both of said metal plates.
Claim 3
Dependent Claim 25 words
An IC card according to claim 1 wherein said means electrically connecting said ground-connection point to both said metal plates comprises a single lead wire.
Claim 4
Dependent Claim 135 words
An IC card having an integrated circuit sealed within, comprising: a case constructed of a card-shaped synthetic resin material and internally incorporating an integrated circuit board, said case having a recess defined in an end thereof, and opposite surfaces; a connector portion disposed on said end of the case and having contact pins positioned within said recess for connecting said integrated circuit board to an external circuit; and a reinforcing metal plate covering each of said opposite surfaces of the case, each said metal plate further including an integral end portion bent into an L-shaped configuration toward an inlet region of said recess in covering relation to a portion of the connector portion around the inlet region of the recess, said integrated circuit board having a ground-connection point electrically connected to said reinforcing metal plates.
Claim 5
Dependent Claim 135 words
An IC card having an integrated circuit sealed within, comprising: a case constructed of a card-shaped synthetic resin material and internally incorporating an integrated circuit board, said case having a recess defined in an end thereof, and opposite surfaces; a connector portion disposed on said end of the case and having contact pins positioned within said recess for connecting said integrated circuit board to an external circuit; and a reinforcing metal plate covering each of said opposite surfaces of the case, each said metal plate further including an integral end portion bent into an L-shaped configuration toward an inlet region of said recess in covering relation to a portion of the connector portion around the inlet region of the recess, said integrated circuit board having a ground-connection point electrically connected to said reinforcing metal plates.
