Abstract

Abstract An IC card includes a circuit board for mounting electronic parts, a frame surrounding the circuit board, and panel covering each of the front and back sides of the circuit board and the frame. Spacers serving as supporting members are adhered to the circuit board by soldering. Soldering can be performed by the same process as soldering electronic parts to the circuit board so as to prevent deformation of the panels and application of excessive force to the electronic parts even if an external force is applied to the panels.

Dependent Claim 66 words
An IC card comprising: a circuit board for mounting electronic parts; a frame surrounding said circuit board; respective panels covering each of front and back sides of said circuit board and said frame; and a supporting member arranged in a gap between said circuit board and one of said panels for supporting said panel, wherein said supporting member and said circuit board are a unitary body.
Claim 3
Dependent Claim 69 words
An IC card comprising: a circuit board; electronic parts mounted on said circuit board; a frame surrounding said circuit board; respective panels covering each of front and back sides of said circuit board and said frame; and a supporting member disposed in a gap between said circuit board and one of said panels for supporting said panel, wherein said supporting member and said one of said panels are unitary.
Claim 4
Dependent Claim 69 words
An IC card comprising: a circuit board; electronic parts mounted on said circuit board; a frame surrounding said circuit board; respective panels covering each of front and back sides of said circuit board and said frame; and a supporting member disposed in a gap between said circuit board and one of said panels for supporting said panel, wherein said supporting member and said one of said panels are unitary.
Claim 5
Dependent Claim 79 words
An IC card comprising: a circuit board; electronic parts mounted on said circuit board; a frame surrounding said circuit board; respective panels covering each of front and back sides of said circuit board and said frame; and a supporting member disposed in a gap between said circuit board and one of said panels, said supporting member including a transverse part in the gap for supporting said panel and a lateral part extending between an electronic part and said panel.
Claim 6
Dependent Claim 79 words
An IC card comprising: a circuit board; electronic parts mounted on said circuit board; a frame surrounding said circuit board; respective panels covering each of front and back sides of said circuit board and said frame; and a supporting member disposed in a gap between said circuit board and one of said panels, said supporting member including a transverse part in the gap for supporting said panel and a lateral part extending between an electronic part and said panel.
Claim 7
Dependent Claim 52 words
The IC card of claim 3 wherein said supporting member includes a second transverse part extending from the lateral part and disposed in the gap between said circuit board and said one of said panels for supporting said panel wherein the electronic part is surrounded on three sides by said supporting member.
