Abstract
PURPOSE:To prevent mistaken cutting, by confirming the presence of an undeveloped part of a fixded width near an imaginary cutting position presumed located at a given distance from one end of a roll film. CONSTITUTION:It is detected by density measurement that there is an (e) wide undeveloped part on the position nearest to (a) in the range of a given distance of a+alpha-a+beta from one end O of a roll film. Then, the presence of a notch N on the upstream or downstream position gamma from the center of the undeveloped part (e) is confirmed, and the film is cut at the center C of the part (e), thus permitting an accident that the film is cut at the position of a precious image never to be caused.
