Abstract

A processing apparatus is provided for immersion treating a sheet-like film unit with a processing liquid and thereafter squeegeeing excess liquid therefrom. The apparatus includes a processing tank holding a supply of liquid, a pair of pressure applying rollers for withdrawing the film unit from the tank and squeegeeing excess liquid therefrom, a movable film carrier for supporting the film unit at a processing position in the liquid and then raising the film unit to position where it feeds an end of the film into the rollers, and means responsive to rotation of the rollers for automatically moving the carrier from the processing position to the film feed position.
