Title: Card device and mounting device for the same
Inventor: KATAOKA YASUHIRO
IPC: G06K19/077
Filed: 1997-08-11
Abstract: PROBLEM TO BE SOLVED: To make a device thin and to secure sufficient reliability by providing a shutter, which prevents an electrode from being exposed at a protection position and exposes the electrode at a connectable position. SOLUTION: A memory card 10 has the shutter 28 arranged on the side where the card is inserted into an insertion slot, so that the shutter can be opened and closed, and the terminal connected to information equipment 11 is protected by this shutter 28. While the card is not mounted on the information equipment 11, the shutter 28 has its insertion-side tip held at the protection position nearly matching the insertion-side tip of the memory card 10. When the shutter 28 is inserted into a socket housing 15 after being set in a displaceable state by operating a shutter lock 29, it slides away from the insertion side to expose the insertion-side tip of an upper package.  Thus, the shutter clock 29 forms a limiting mechanism, which limits the displacement of the shutter 28 to the connectable position, while the memory card 10 is in a state of not being mounted on the information equipment 11.
