Abstract
A transport mechanism has two driven gears driven by a driving gear therebetween and having pivotally attached cranks at pivot points maintained at the same elevation as the driven gears rotate. The upper end of the cranks are attached to a horizontal moving guide bar. The moving mechanism is supported beside a fixed guide plate formed with a loading slot at the input end, a sloping edge at the output end and a number of equally spaced vertical slots therebetween. A film carrier has end rods which may rest on the moving guide bars and be lowered in the slots. Film chips in the film carrier advance from the loading slot into a developing tank. The mechanism then lifts the carrier with the film chips above the carrier tank and into a wash tank, then from the wash tank into a fixing tank, then from the fixing tank into a wash tank, then into a drying chamber and then upon an output ramp.
