ABSTRACT:
In some types of processing apparatus, there is a minimum length of film strip which can be processed. To overcome this problem, several film strips may be spliced together to provide the desired length and/or a leader attached to the leading edge of the film strip to guide it through the apparatus for processing. Described herein is a loading device (10) for photographic processing apparatus which allows a length of film (102) to be unloaded from its cassette (100) in a film unloading station, its length checked at a film length checking station (18), and passed to a storage station (16) prior to being directed to the processing apparatus. Any length of film not exceeding the minimum length requirement for the processing apparatus can be removed from the storage station thereby avoiding film jams because the film is too short to pass from one transport station to another in the processing apparatus.
