Abstract
An X-ray film processor having a double tank construction wherein the drive rollers for transporting the film in a straight line horizontally through the processor are disposed in an upper film processing tank and above the normal level of the processing liquid in a lower, reservoir tank. A pump is used to artificially raise the level of the liquid in the upper tank to a level above the drive rollers so as to submerge both the drive rollers and the film being transported in the processing liquid.
