Abstract: PROBLEM TO BE SOLVED: To restrain tendency that the cut fraction of a photographic film adheres to the edge body of a cutter even though the edge body is used for a purpose that the needless protruding part of the film is cut by sticking a discharge film body on at least one of a pair of edge bodies. SOLUTION: An edge surface 132a horizontally extending toward the crossing direction of the film 2 is formed on a movable upper edge body 132, and a horizontal planar edge surface 134a is formed on a fixed lower edge body 134. A discharge paper 160 is stuck to the each edge surface 132a of the body 132 in order to restrain a phenomenon that the separated fraction 2b adheres especially to the body 132 by static electricity. Thus, electrifying tendency is drastically reduced, so that the the greater part of the fraction 2b of the photographic film freely falls below the device just after the fraction is produced without adhering to the body 132 of the cutter. Consequently, a problem that the part of the adhering fraction 2b is carried to an exposure part with the photographic film while being stuck to the image surface of the photographic film main body and disturbs exposure operation can be remarkably reduced.
