Abstract

An IC card having a connection portion, a changeover switch and card-shaped memory means in which an integrated circuit is accommodated within a prescribed case and has a processor and memory. Lead portions for connecting contact pins of said connecting portion and switch terminals of said switch to an internal circuit pattern, are packed in an insulating adhesive in order to provide a case with a hermetic structure.

Claims

1. An IC card having a connector portion and a changeover switch that are led out from a circuit pattern incorporating a semiconductor integrated circuit, the IC card comprising:

connector means formed integral with said connector portion and changeover switch;

lead means for connecting connector pins of said connector means and contact terminals of said changeover switch with said circuit pattern;

a case for accommodating said circuit pattern, which includes said semiconductor integrated circuit,

said case having a cover, a back and four sides with three of said sides being comprised of solid wall portions and one of said sides having openings therein to accommodate said connector pins and said switch whereby said connector pins and said switch are both mounted in said one side; and

an electrically insulating packing material provided inside said case around said lead means adjacent said openings in said one side to hermetically seal said case.

2. An IC card as set forth in claim 1, wherein said switch comprises a rotary switch having a circular rotatable body member with a resilient contact spring attached to an inner end thereof for contact with said contact terminals, said body member having a guide groove around its outer periphery for engaging a projection in said one side of said case.
