Abstract:
1. An integrated circuit (IC) card connector comprising: a housing forming a card accommodating portion configured to selectively and detachably house any one of a first IC card and a second IC card, the first and second IC cards each having a plurality of electrode pads, the first and second IC cards having data transmission speeds different from each other, the electrode pads of the first IC card being arranged at the same intervals as those at which the electrode pads of the second IC card are arranged; grounding contact terminals, respectively, for the first IC card and the second IC card, the grounding contact terminals being disposed in the card accommodating portion, the grounding contact terminals including contact portions configured to come into contact with grounding line electrode pads of the first IC card and the second IC card when the IC card is mounted in the card accommodating portion; a first data transmission contact terminal and a second data transmission contact terminal provided in the card accommodating portion and disposed so as to be adjacent to the respective ground contact terminals and to face each other along a direction of mounting and demounting of the first IC card and the second IC card, each of the first data transmission contact terminal and the second data transmission contact terminal including a contact portion configured to come into contact with data transmission electrode pads of the first IC card and the second IC card when the IC card is mounted in the card accommodating portion; and a card detection contact terminal being provided substantially at a central part of the card accommodating portion and adjacent to the first data transmission contact terminal and the second data transmission contact terminal, the card detection contact terminal including a contact portion configured so that, when one of the first IC card and the second IC card is mounted in the card accommodating portion, the contact portion comes into contact with a card detection electrode pad of the mounted IC card, thereby detecting the mounting of the mounted IC card, wherein, when any one of the first IC card and the second IC card is inserted to the card accommodating portion, the contact portions of the grounding contact terminals are brought into contact with the grounding line electrode pads, the contact portions of the first data transmission contact terminal and the second data transmission contact terminal are then brought into contact with the data transmission electrode pads, and the contact portion of the card detection contact terminal is brought into contact with the card detection electrode pad after a lapse of a predetermined time period, thereby detecting the mounting of the inserted IC card.
