Abstract

A transport mechanism for film cards having two rocker levers supported on a pivoting lever that can swivel around a shaft, with the rocker levers being capable of pivoting around a rocker lever shaft. The two rocker levers, in turn, support two opposite discs, one of which is driven by a motor. A gripping motion of the discs is brought about by provision of guide grooves located on the rocker levers, with each groove accommodating a stationary pin. Through provision of an intermediate carrier, the upper disc is fixed to the upper rocker lever in a manner that it can pivot around a horizontal axis which is at right angles to the rocker lever shaft. Therefore the upper disc can be tilted in the respective direction of transport.
