KARTENFOERMIGES INFORMATIONSSPEICHERMEDIUM.

摘要

For protecting a semiconductor chips from an electric destruction due to electrostatic charges, there is disclosed a card-shaped information storage medium used for providing data informations to an information processing unit comprising a) a board member (1) of an insulating material having an first occupation area for at least one semiconductor chip (3/4/5/6/7) capable of preserving the data informations and a second occupation area for a plurality of communication terminals (10) electrically coupled to the semiconductor chip, b) a protective member (8) covering the semiconductor chip and exposing the communication terminals to the outside thereof, and c) a protective shutter (9) movable into or out of the protective member for shifting a position of the information storage medium between a closed state and an open state, so that the communication terminals are covered with the protective shutter in the closed state, thereby preventing the communication terminals from a human body with the electrostatic charges.
