Abstract

A memory card includes a card body having an integrated circuit incorporated therein, and having a plurality of internal and external electric signal-connection terminals. The respective terminals of the integrated circuit are electrically connected to a plurality of electric signal-carrying members. The electric signal-carrying members have contact terminals for electrical connection to a card information-processing unit. The contact terminals are exposed on the upper surfce of the card body. The memory card has a protective cover which is slidably movable in two predetermined directions on the card surface. When the memory card is in use, the protective cover is movable in one of the two predetermined directions, whereby the respective contact terminals are exposed, and when the memory card is not being used, it is movable in the other direction, whereby it covers the respective contact terminals. The protective cover has a surface which faces the card body. The protective cover also has a short-circuiting member for electrically short-circuiting the respective contact terminals at the facing surface side of the protective cover, when the protective cover covers the respective contact terminals.

Dependent claims

A memory card for use in a card information-processing unit, to allow information contained in the card to be processed, comprising:

a card body having a main surface;
at least one integrated circuit incorporated in the card body, and having a plurality of internal and external signal-connection terminals;
a plurality of electric signal-carrying members electrically connected to respective terminals of the integrated circuit, and having contact terminals for electrical connection to the card information-processing unit, the contact terminals being exposed in a predetermined pattern on the main surface of the card body;
a protective cover having a surface facing the main surface of the card body, and being slidably movable in two predetermined directions on the main surface of the card body, the protective cover being movable in one of the two directions, so that when the memory card is being used, the respective contact terminals may be exposed, and being movable in the other direction, so that when the memory card is not being used, the respective contact terminals may be covered;
and
short-circuiting means provided on the surface of the protective cover, for electrically short-circuiting the respective contact terminals when the protective cover covers the respective contact terminals.
