Abstract
Abstract A card-type processing device such as an IC card is comprised of an electronic circuit element mounted on a circuit board and a housing which encloses them both inside. The part of the housing which actually encloses the circuit board and the circuit element is rigid but the remaining parts are made flexible such that an internal stress caused by external force is absorbed by the flexible parts and the circuit element is not damaged by the propagating stress.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
44 words
A card-type processing device comprising a circuit board with electronic circuit elements mounted thereon and a planar housing structure with a central part which is rigid and enclosingly contains said circuit board and a peripheral part which is flexible and surrounds said central part.
Claim 2
Dependent Claim
44 words
A card-type processing device comprising a circuit board with electronic circuit elements mounted thereon and a planar housing structure with a central part which is rigid and enclosingly contains said circuit board and a peripheral part which is flexible and surrounds said central part.
Claim 3
Dependent Claim
25 words
The device of claim 1 wherein said housing structure includes an upper plate and a lower plate attached to each other in a face-to-face relationship.
Claim 4
Dependent Claim
38 words
The device of claim 2 further comprising in said central part a first thermosetting tape sandwiched between said circuit board and said upper plate and a second thermosetting tape sandwiched between said circuit board and said lower plate.
Claim 5
Dependent Claim
21 words
The device of claim 3 further comprising an adhesive tape sandwiched between said upper and lower plates in said peripheral part.
Claim 6
Dependent Claim
23 words
The device of claim 2 wherein said lower plate is formed with an indentation, said electronic circuit elements being disposed inside said indentation.
Claim 7
Dependent Claim
22 words

Claim 8
Dependent Claim
30 words
The device of claim 3 wherein said thermosetting tapes are attached firmly to said circuit board and said upper and lower plates so as to form together a rigid structure.
Claim 9
Dependent Claim
14 words
The device of claim 2 wherein said upper and lower plates comprise vinyl chloride.
Claim 10
Dependent Claim
16 words
The device of claim 1 wherein said circuit board is contained only in said central part.
Claim 11
Dependent Claim
26 words
