ABSTRACT:
An IC card has a shutter reciprocatively mounted on a frame in order to protect a plurality of external-element connection terminals which are mounted on the frame. Guide grooves formed in the frame include those which receive corresponding projections formed on spring-mounting portions of the shutter to keep the projections in engagement therewith, thereby enabling both the base portion and the spring-mounting portion of the shutter to be guided. End portions at one end of those guide grooves determine a position of the shutter such that the shutter is prevented from overshooting the frame. Thus, the IC card is capable of ensuring stable opening and closing action of the shutter.
