PURPOSE: To prevent the generation of electric conduction failure, etc. due to abrasion of a conductive part even if a memory card is attached and detached many times, by providing a freely openable and closable cover body so as to cover a containing part of the memory card on which a press-contact type connector is provided.

CONSTITUTION: A contact pattern 10 is provided on the upper face of the tip part of a memory card 4, a freely openable and closable cover body 12 is provided on the reverse side of a lower side case 1b of an electronic apparatus body, and a containing part 13 of the memory card 4 is formed on the inside of this cover body 12. A press-contact type connector 11 which is in contact with the contact pattern 10 of the memory card 4 is provided on a part of the containing part 13. The cover body 12 is opened, the memory card 4 is fitted into the containing part 13, the contact pattern 10 and the press-contact type connector 11 are brought into contact with each other, and the cover body 12 is closed. As for contact of the contact pattern 10 and the press-contact type connector 11, they are connected electrically without executing fitting or sliding, therefore, no abrasion is caused.
