Abstract
An apparatus for developing photosensitive material has a processing bath, and transporting devices for advancing several strips and/or sheets of photosensitive material through the bath side-by-side. The strips and sheets have various widths. A sensing system is provided to sense the surface area of the material advanced through the bath. The sensing system includes a plurality of spaced sensors arranged in a row which traverses the path of the material. The sensors are designed to sense the widths of the strips and/or sheets, and adjacent ones of the sensors are spaced from one another by a distance smaller than the magnitude of the smallest difference between the widths of the strips and/or sheets. The lengths of the strips and/or sheets are taken into account by a length measuring unit which determines the frequency with which the sensors scan the strips and/or sheets. When a predetermined total surface area is reached, a signal is sent to a control unit which opens a valve for a vessel containing a regenerating solution for the bath. A predetermined quantity of the regenerating solution then enters the bath.
