Abstract
Extra printing is made possible during a set of ordinary processing operations such as film development and printing. A film is developed and dried while being fed by a leader attached thereto. After cutting the leader from the film, it is fed to the printing unit to print the images on the film onto photographic paper. A plurality of film stocking units are provided in a path from the film drying unit to the printing unit. Each stocking unit can selectively stock a single film or allow it to pass without stocking. A second film stocking unit can move laterally to change the film track. If a film requiring a long exposure time is present in the printing unit, the subsequent films that have been developed and dried can be stocked in the other film stocking units. Thus, continuous film developing operations are not interrupted.
