Abstract
A reliable machine for developing film, which minimizes the possibility of damage to the film surface and which provides close control of processing conditions. A film strip is pulled by a detachable member attached at the front end of the strip, and is guided along the machine by rollers spaced along the film path, with each roller having a film-supporting surface at each end and a wide cutaway portion between the film-supporting surfaces so that each roller touches only edge portions of the film. Chemicals in the tank are replenished by a system which includes a plunger that moves down into the tank to cause some of the chemicals to overflow into a drain and which then moves up out of the tank to lower the fluid level therein, and a bottle with an open lower end which supplies chemicals to restore the fluid to its original level.
