  • Publication number: 20100184310
    Abstract: An IC card includes a frame with a rectangular border open on one side, a printed circuit board equipping an electronic component, a plate-shaped connector, and one pair of conductive shell plates. The connector constitutes one side of the frame. The one pair of shell plates covers both faces of the frame and the connector. The connector has a housing, a plurality of male contacts arranged in parallel in the interior of the housing, and a short circuit terminal. The male contacts are such that one end portion is a connecting portion to an external terminal and another end portion is connected to the printed circuit board. The short circuit terminals are mounted on the housing such that one end portion is in contact with a predetermined male contact among the plurality of male contacts and another end portion is in contact with an inner wall of a shell plate.

  • Publication number: 20100130041
    Abstract: A card connector includes a housing inserted a card therein, a slider, a rotating cam member having a shaft portion that is retained so as to be rotatable by the slider, and a compression coil spring that biases the rotating cam member. The slider includes second chevron teeth that engage with first chevron teeth provided at an end of the rotating cam member. The rotating cam member is provided with a first broad protrusion and a second narrow protrusion alternately at an outer circumference of the shaft portion. When inserting the card, since the rotating cam member turns by a predetermined angle so that the first protrusion faces the starting end of the passage groove, the slider is locked. When pushing the card again, since the rotating cam member turns by a predetermined angle, the second protrusion faces the starting end of the passage groove, the card can be ejected.

  • Publication number: 20100096090
    Abstract: A sticking apparatus includes a sticking table 21 for supporting a semiconductor wafer W and a sticking unit 24 that peels off an adhesive sheet S1 from a release liner PS and sticks the adhesive sheet to the semiconductor wafer W. The sticking unit 24 has a detector 60. The detector 60 is disposed above a feed-out path of a raw strip sheet L for detecting a displacement amount S of the adhesive sheet S1 in the lateral direction perpendicular to the feed-out direction thereof. When the displacement amount S is detected, a displacement correction device 51 is activated and the sticking table 21 is moved by a distance corresponding to the displacement amount S, thereby the adhesive sheet S1 can be stuck onto the semiconductor wafer W in accordance with the outer shape thereof. The adhesive sheet S1 is stuck onto the wafer W by a sticking roll 61, which is brought into a contact with the release liner PS to impart a pressing force thereto.
