Abstract
A reader for chip cards with a housing (3) featuring an insertion slot (1) for the chip card (2), a number of pairs of contacts (6,7) corresponding to the number of read tracks, and a contact support frame (5) connected to the contact lead-ins (4), in which the contact lead-ins (4) held in the housing (3) are inserted in parallel from one side into the contact support frame (5) held in a free suspension by the contact lead-ins (4). On the side of the contact support frame (5) turned away from the contact lead-ins (4) there is an actuator element designed as a double arm lever (9, 10). The actuator element is held in the housing (3) by a transverse torsion spring arm (8) and its power arm (9) lies in the insertion path of the chip card (2) such that the work arm (10) of the actuator lever is twisted during insertion of the chip card (2) under tension of the torsion spring arms (8) and the contact support frame (5) and thus its associated contacts (6,7) are pressed against the chip card (2). The contact support frame (5) is provided with lateral pins (14) and the work arm (10) of the actuator element (8, 9, 10) is designed as a fork whose tines in their released position rest loosely…
