Abstract
Abstract An IC card has a contact portion which is exposed on one surface of a printed circuit board and has multiple terminals provided to electrically contact an external device. Wirings are arranged on the other surface of the printed circuit board at a position facing the contact portion with the printed circuit board in between, and are printed at least at positions opposite to gaps between the terminals. The arrangement of the wirings thus prevents that portion of the IC card at the gaps from becoming thinner than the other portion of the IC card.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
83 words
An integrated circuit card device comprising: a printed circuit substrate for supporting at least one of electronic component; contact means disposed on one surface of printed circuit substrate having multiple terminals provided with gaps therebetween for electrically contacting with an external device; and a circuit printed on the printed circuit substrate, for connecting the contact means and the electronic component and having at least a portion placed below said gaps, said printed circuit being broader than each of said gaps between said terminals.
Claim 2
Dependent Claim
83 words
An integrated circuit card device comprising: a printed circuit substrate for supporting at least one of electronic component; contact means disposed on one surface of printed circuit substrate having multiple terminals provided with gaps therebetween for electrically contacting with an external device; and a circuit printed on the printed circuit substrate, for connecting the contact means and the electronic component and having at least a portion placed below said gaps, said printed circuit being broader than each of said gaps between said terminals.
Claim 3
Dependent Claim
39 words
An IC-card according to claim 1, wherein the conductor tracks which are opposite to the intermediate spaces and which extend parallel thereto are broader in the region of the parallel arrangement than in the region of the non-parallel arrangement.
Claim 4
Dependent Claim
36 words
An IC-card according to claim 1, wherein the electronic component is arranged opposite to the contact portion on the other side of the substrate and the conductor tracks lie between the electronic component and the substrate.
Claim 5
Dependent Claim
112 words
An IC-card device comprising: a substrate having conductor structures as a carrier for at least one electronic component; a contact portion which is disposed on a surface of the substrate and which has multiple terminals for electrical connection to an external device and is provided with gap-like intermediate spaces between the terminals; and conductor tracks which are disposed on the side of the substrate opposite to the contact portion and which connect the contacts of the contact portion to the electronic component, the intermediate spaces being bridged over on the side of the substrate opposite to the contact portion by portions of conductor tracks which are broader than the respective intermediate spaces.
Claim 6
Dependent Claim
112 words
An IC-card device comprising: a substrate having conductor structures as a carrier for at least one electronic component; a contact portion which is disposed on a surface of the substrate and which has multiple terminals for electrical connection to an external device and is provided with gap-like intermediate spaces between the terminals; and conductor tracks which are disposed on the side of the substrate opposite to the contact portion and which connect the contacts of the contact portion to the electronic component, the intermediate spaces being bridged over on the side of the substrate opposite to the contact portion by portions of conductor tracks which are broader than the respective intermediate spaces.
Claim 7
Dependent Claim
16 words
An IC-card according to claim 4, wherein portions of conductor tracks perpendicularly cross the intermediate spaces.
