ABSTRACT:
A card-receiving host having a simple push latch/unlatch mechanism to aid in withdrawal of an inserted IC card. The host (24, FIG. 2) has dual push latch/unlatch mechanisms (54) which allows the card (16) to be fully inserted and latched when first pushed forward, and, after a second push on the card, unlatches the mechanisms and moves the card rearward by an amount predetermined by the latch implementation to facilitate grasping it to pull it out of the host. In one arrangement the host connector has a male pin assembly that is free to move in and out to accommodate the latch lost motion and to provide the means to transfer the latch spring pressure and motion to the IC card for its rearward travel. The host connector male pins are, in this implementation, terminated to the electronic device frame via a flexible cable (94), in another system (FIG. 9), a pair of actuators, (164, 166), are implemented to operate the latch mechanisms and can be implemented such that the second thrust of the card (to unlatch), will cause the card to be pushed out far enough so that the card contacts (50) are substantially unmated from the host connector contacts, (172).
