Abstract

In a device for friction-driven conveyance of a card-shaped recording medium (14), such as an I.D. card, relative to an evaluation device (16) which is situated on an extended linear transport path (36) between an inlet (38) and an outlet or reversal point (40), the linear transport path (36) is bordered on the one side by a section of a closed-loop conveyor (26) and on the other side by a pressure strip (28) which runs approximately parallel to the path (36) and is stressed toward the conveyor (26) with the aid of a pressure device (52). Rollers as active transport elements are thereby eliminated, insuring error-free transport of even deformed recording media.
