ABSTRACT:
An improved IC card ejecting mechanism including an ejecting lever that turns about two fulcrums, one after another, to eject an IC card from an underlying connector apparatus. Specifically, the ejecting lever first turns about a first fulcrum which is placed close to an ejecting end of the lever to provide a relatively large moment arm and to permit disengagement and initial ejection of the card with a relatively small applied force. The ejecting lever then turns about a second fulcrum which is placed close to the opposite end of the ejecting lever to increase the distance of travel of one end of the card outside a card opening.
