An apparatus for processing an elongate photographic photosensitive film has a cutting mechanism for cutting the elongate photographic photosensitive film, first and second feed mechanisms disposed one on each side of the cutting mechanism, an inserting mechanism for inserting the leading end of the elongate photographic photosensitive film into a spool, and a cam switching mechanism for changing the timing of operation of the cutting mechanism depending on any one of predetermined lengths. The leading ends of sized films of different lengths that are cut from the elongate photographic photosensitive film can automatically be inserted into spools with a relatively simple arrangement.
