ABSTRACT:
A photographic film take-up device having: a holding device for holding a cartridge main body accommodating a spool having a trailing end engaging member in an interior thereof, the trailing end engaging member engaging a trailing end portion of an elongated photographic film, an interior portion of the cartridge main body being shielded from light; and a guiding member having an engaging portion which engages the longitudinal direction trailing end portion of the film, and engaging the engaging portion with the trailing end portion of the film, and guiding the engaging portion and the trailing end portion of the film to the spool via a film path provided in the cartridge main body, and engaging the trailing end portion of the film with the trailing end engaging member. The engaging portion is provided at a leading end portion of the guiding member in a direction of guiding the film to the spool, and engages an engagement hole provided in a central portion of the film at the longitudinal direction trailing end portion thereof. When the engagement portion is engaged with the engagement hole of the trailing end portion of the film, curling of the film such that a longitudinal direction central portion thereof is separated from the guide member can be deterred. Guiding and engagement can be effected smoothly and reliably.
