Abstract:
An IC protective in a memory card operating electronic apparatus comprising a plurality contacts arranged in a front and a rear row such that they come in contact with a corresponding plurality of electrode pads arranged in a front and a rear row on a memory card when the memory card is inserted into an electronic apparatus, in order to prevent an electrical charge of a charged part held by an electronic circuit within the electronic apparatus from flowing to an IC within the memory card or IC of an electronic circuit within the electronic apparatus when the contacts in the front and the rear row slide on surfaces of the electrode pads in the front and the rear row at the same time during a process for inserting and withdrawing the memory card into and from the electronic apparatus, wherein a discharge circuit for the charge part is formed in operative connection with the inserting and withdrawing movement of the memory card.
