ABSTRACT:
An arrangement for developing or fixing film has a container for accommodating a developing or fixing solution. A pair of spaced strips or sheets extend across the container. The surfaces of the strips or sheets which face one another are provided with a series of aligned slots. The slots are designed to receive roller racks for transporting film through the developing of fixing solution. The spacing and arrangement of the slots are such that several racks having the same width, or several racks having different widths, may be arranged side-by-side in the container. Each rack has a main gear which drives all of the rolls of the respective rack. The main gears of adjacent racks are coupled to one another while the main gear of one of the racks is further connected to a drive located outside of the container. This drive thus actuates all of the racks in the container. The racks have alignment rods for aligning the racks relative to one another and to the container. The arrangement makes it possible to process several films simultaneously regardless of whether or not the various films have the same width or different widths. The racks may have different lengths so that different dwell times in the developing or fixing solution may be obtained. This makes it possible to simultaneously process films having different sensitivities and/or films produced by different manufacturers.
