Abstract
The film forwarding device of the present invention includes: a take up spool which takes up a film upon a circumferential outer surface of the take up spool, the film having, upon a leading end of the film, a projecting portion a normal line to which is substantially parallel to a direction of forwarding of the film, and a sloping portion, connected to the projecting portion, which slopes with respect to a transverse direction perpendicular to the direction of forwarding the film; a pressure member which presses the film against the circumferential outer surface of the take up spool; and an advancing mechanism which pushes out the film from a film cartridge and advances the film at least until taking up of the film by the take up spool has started, wherein the pressure member is located so as to initially come into contact with the projecting portion of the leading end of the film, when the taking up of the film by the take up spool starts.
