IC MEMORY CARD, HOST APPARATUS SIDE CONNECTOR AND CONNECTING SYSTEM USING THE SAME

摘要

PURPOSE:To obtain an erroneous insertion preventing mechanism for preventing erroneous insertion of an IC memory card into a host apparatus side connector by enhancing multipolarization of the connector of the card. CONSTITUTION:A connector 11 is provided at a long side of an IC memory card 18. A thickness t1 of a connector part 18a provided with the connector 11 is formed thinner than that t2 of a body part 18b of the other region of the card 18 except the part 18a, and a height (h) of inside of a connector guide of a host apparatus side connector is set to a range of t1
