ABSTRACT:
A primary drive assembly which drives photosensitive material through a photographic processor is provided at a point of a photoprocessing path of the processor at which a precise speed control is desired. A secondary drive assembly is provided downstream of the primary drive assembly at the end of the processor to pull the photosensitive material through the end of the processor. The primary drive assembly includes a control member which controls the speed of the secondary drive assembly based on the tension of the photosensitive material in the vicinity of the primary drive assembly. If the tension is below a predetermined point, the speed of the secondary drive assembly is increased, and if the tension is too high, the speed of the secondary drive assembly is decreased. The primary drive assembly uses a pivotable roller arrangement in combination with a switch to monitor tension and supply a signal to the secondary drive assembly.
