Abstract
Abstract Described herein is a method and apparatus (10) for processing a filmstrip contained in a film cartridge. The apparatus (10) comprises an unloading/loading station (12), a film processing section (14) comprising a plurality of processing tanks (74, 76, 78, 80, 82, 84), each holding a processing solution, and a drying station (16) arranged in a housing (18). The filmstrip is loaded into a reel assembly in the unloading/loading station (12) for processing in each processing tank (74, 76, 78, 80, 82, 84) of the processing section (14), the filmstrip having a trailing edge which is secured to the cartridge with only the exposed portion thereof being retained in the reel assembly. A film drive mechanism is used for moving the film out of or back into the film cartridge while the trailing edge is still attached to the cartridge. The apparatus further includes a transport mechanism for moving the reel assembly along the apparatus so that it can be located at each processing tank (74, 76, 78, 80, 82, 84).
