IC card with retractable tray

摘要

An IC card (210) has a tray (214) that carries a fingerprint sensor (220). The tray can be slid rearwardly (R) out of the rear end of the card to a deployed position wherein the fingerprint sensor is exposed, the tray then being slidable forwardly (F) to a stowed position. A tension spring (236) urges the tray rearward toward the deployed position and a double click mechanism releases the tray to move rearward when the stowed tray is pushed slightly forward. A cam element of the mechanism is integrally molded into the tray while a cam follower element (272) of the mechanism is integrally molded into a tray guide (250). The tension spring is located in an isolated area (350) between one side of the tray guide and a side of the IC card housing. <IMAGE>
