ABSTRACT:
A photographic film separation method. A spool has a slit, a first rod-shaped member and a second rod-shaped member. The second rod-shaped member has a lower rigidity than that of the first rod-shaped member so that the second rod-shaped member is flexibly deformable. The first rod-shaped member has an engagement member which engages one longitudinal direction end portion of a photographic film. The second rod-shaped member has a presser pawl which maintains engagement between the photographic film and the engagement member. The separating member has a higher rigidity than that of the second rod-shaped member, and has a tip end portion which penetrates substantially simultaneously to positions at which the engagement member and the presser pawl are provided. The separating member is inserted between the engagement member and the photographic film positioned inside the slit, and releases the engagement between the photographic film and the engagement member. The second rod-shaped member as a whole has a low rigidity. Accordingly, when the separating member is inserted into the slit, the second rod-shaped member is lifted upward together with the presser pawl by the separating member, so that the photographic film engaged by the engagement member can easily be pulled out by a small force and without any damage, such as rubbing or the like, to the film.
