ABSTRACT:
Photographic film handling equipment is disclosed, wherein photographic film is positioned relative to a photographic lens system. The film is advanced in a first direction by a film transport mounted on a carriage which is restricted by bars to movement in opposed parallel second and third directions. The carriage is driven via an endless timing belt disposed in a loop having a straight portion extending parallel to the latter second and third directions. Motive power is transmitted from the timing belt to the carriage by a bracket connected to the straight loop portion of the timing belt. A motor drives the timing belt in opposite senses.
