Abstract
Abstract 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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
129 words
A card-shaped information storage medium used for providing data informations to an information processing unit comprising a board member of an insulating material having an first occupation area for at least one semiconductor chip capable of preserving the data informations and a second occupation area for a plurality of communication terminals electrically coupled to the semiconductor chip, a protective member of an insulating material covering the semiconductor chip and exposing the communication terminals to the outside thereof, characterized by a protective shutter 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, the communication terminals being covered with the protective shutter in the closed state, the communication terminals being exposed in the open state.
Claim 2
Dependent Claim
129 words
A card-shaped information storage medium used for providing data informations to an information processing unit comprising a board member of an insulating material having an first occupation area for at least one semiconductor chip capable of preserving the data informations and a second occupation area for a plurality of communication terminals electrically coupled to the semiconductor chip, a protective member of an insulating material covering the semiconductor chip and exposing the communication terminals to the outside thereof, characterized by a protective shutter 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, the communication terminals being covered with the protective shutter in the closed state, the communication terminals being exposed in the open state.
Claim 3
Dependent Claim
41 words
A card-shaped information storage medium as set forth in claim 1, in which said information storage medium further comprises stopper means operative to limit the movement of said protective shutter when the protective shutter is moved out of said protective member.
Claim 4
Dependent Claim
46 words
A card-shaped information storage medium as set forth in claim 2, in which said information storage medium further comprises elastic means operative to urge said protective shutter to move for shifting the position of said information storage medium from said closed state to said open state.
