Abstract

See full text

Apparatus for scanning a data card which comprises a thin, flexible medium having leading and trailing edges and one or more data stripes formed thereon at a prearranged location and extending transverse to said leading and trailing edges. The apparatus comprises a card guide for defining a linear card guide path and an entrance slit for accepting the data card into the guide path. A card positioning assembly is cooperatively associated with the card guide and drives the data card through the entrance slit and into the card guide. The card positioning assembly positions the card in a stationary prearranged location. A transducer positioning assembly linearly scans transducers along the data stripes on the data card.
