ABSTRACT:
A film processor of the type which includes a sheet transport having a finger pushing the rear edge of the film sheet while edge guides guide the edges of the film along a path that leads down into each of a series of tanks and up out of each tank in a loop over to the next tank, including a loop guide at the end of each loop for guiding the middle of the film sheet around the loop. The loop guide includes a pair of guide plates lying near the center of the film path on either side of a finger-moving belt, each plate having a concave surface extending along the radially outside portion of a loop to guide the leading edge of a film sheet which tends to bow outwardly as the sheet moves along a curve.
