Abstract

A reader/writer apparatus for a contact-type smart card and having a frame forming a card slot for receiving a smart card and a landing contact mechanism carried on the frame for making electrical contact with contact pads on the smart card when inserted in the card slot. The landing contact mechanism includes a connector carriage carrying a card contact set thereon facing the card slot and mounted to the frame on a pivot axis defined thereon such that the connector carriage rotates generally in a plane parallel to the card slot. A drive post formed on the connector carriage contacts a leading edge of a smart card inserted in the card slot to rotate the connector carriage through a prearranged angle as the card moves to a predetermined read position within the card slot. Cooperative screw threads on the connector carriage and the frame move the connector carriage a predetermined distance into the card slot as it rotates through the prearranged angle to thereby bring the connector carriage to a read position with the card contact set in contact with contact pads on the smart card.
