Abstract

Abstract A credit card type small thin rectangular IC card (10) includes a battery (14) and an IC comprising a CPU (15), a ROM (15ʺ) and a RAM (15ʹ) mounted on a flexible printed circuit (11) and bonded within an insulative plastic material (12). The printed circuit of the card includes a plurality of electrode terminals (13) exposed in a parallel array along at least one edge of the card which are adapted to engage electrodes of a mating contact. The printed circuit terminals are manufactured by coating copper, nickel and gold over polyamide resin and squeeze finishing the leading edge. The mating socket comprises a generally U-shaped frame having a U-shaped channel adapted to receive the IC card and having internal recessed contacts adapted to engage the terminals of the IC card. The contacts extend from an exterior surface of the frame for interconnection with the circuits of the mating device. Downwardly projecting portions thereof are bent at least twice in the portion penetrating the bottom of the frame.

Claim 1
Independent Claim 64 words
A flexible IC card of the kind provided with plural electrode terminals in parallel and separate array on at least part of its perimeter, which card is coated and bonded with insulating material, characterised in that the card (10) has at least one circuit part including active devices (15, 15ʹ and 15ʺ) and a battery (14) connected by printed circuit (11) on the card.
Claim 2
Dependent Claim 64 words
A flexible IC card of the kind provided with plural electrode terminals in parallel and separate array on at least part of its perimeter, which card is coated and bonded with insulating material, characterised in that the card (10) has at least one circuit part including active devices (15, 15ʹ and 15ʺ) and a battery (14) connected by printed circuit (11) on the card.
Claim 3
Dependent Claim 40 words
A card as claimed in claim 1, characterised in that the electrode terminals (13) are provided and coated on both sides of the card (10) and interconnect the circuit part (11), active devices (15, 15ʹ and 15ʺ) and battery (14).
Claim 4
Dependent Claim 27 words
A card as claimed in claim 1 or 2, characterised in that the circuit part (11) comprises a CPU (15), a ROM (15ʹ) and a RAM (15ʺ).
Claim 5
Dependent Claim 41 words
A card as claimed in any one of the preceding claims, characterised in that the insulating material (12) has voids (16) of about the width of each electrode terminal with a space between each terminal being covered by the insulating material.
Claim 6
Dependent Claim 37 words
A card as claimed in any one of the preceding claims, characterised in that the card (10) is of rectangular shape with the terminals (13) arranged along at least a portion of a side of the rectangle.
Claim 7
Dependent Claim 36 words
A card as claimed in claim 5, characterised in that two sides of the rectangle card (10) at right angles to the side having the terminals (13) are of different cross section to polarise the card.
Claim 8
Dependent Claim 100 words
A mating socket for a card as claimed in any one of the preceding claims characterised in that it has an outer U-shaped frame (21) made of insulating material and having a U-shaped channel (25) in the wall of the frame in cross direction and a number of metal connecting pins (22) in parallel and separate array mounted in the bottom part of the U-shaped frame (21), the pins having terminals (26) projecting downwardly out of the bottom of the U-shaped frame and extending through the frame upwardly inside the channel but not beyond the brim (27) of the channel.
Claim 9
Dependent Claim 37 words
A mating socket as claimed in claims 6 and 7, characterised in that the inside walls of the channel (25) have right and left sides different from each other in configuration of polarisation with the card (10).
Claim 10
Dependent Claim 33 words
A mating socket as claimed in claim 7 or 8, characterised in that the upward portions of the terminals comprise two pieces (24) spring biased together to hold a card terminal (13) therebetween.
Claim 11
Dependent Claim 42 words
A mating socket as claimed in any one of claims 7 to 9, characterised in that the downwardly projecting portion of the terminals (26) are bent twice (28, 29) at least where they extend through the bottom of the U-shaped frame (21).
