ABSTRACT:
There is disclosed a film advancing and processing apparatus for use in conjunction with self-developing film units. Included in such an apparatus is a linear actuator which steps a driving belt that selectively operates a rear film pick mechanism and positively increments a drive roller of a pair of spreading rollers. The linear actuator is operatively positioned between upper and lower belt flights of the belt for providing a compact yet efficient drive system which precisely drives the film pick and the processing rollers.
