Abstract

A plastic card transport apparatus and a plastic card inspection system. A group of lower support wheels is positioned with their circumferential surfaces aligned to define a card transport path having a plurality of card operation locations therealong. The wheels support a plastic card by its lower edge as the plastic card is transported along the card transport path from a first one of the card operation locations to a second one of the card operation locations. A drive source continuously drives selected ones of the lower support wheels to move the plastic card along the card transport path between card operation locations. A controller is responsive to a control signal to drive a selected one of the lower support wheel members, adjacent a first one of the card operation locations, to move the plastic card along the card transport path from that first one of the card operation locations to an adjacent one of the continuously driven lower support wheels, to transport the plastic card to a second one of the card operation locations. The plastic card inspection system includes such a plastic card transport apparatus to transport the plastic cards from a plastic card input location to a plastic card inspection location for inspection, and then to a plastic card output location selected on the basis of the inspection results. The cards are discharged to a tray having a fiber material on its side surfaces to align the cards as they are discharged.
