Abstract

An apparatus in which photographic film is fed out of a film cartridge and is led through a film path to a spool chamber to be wound on a take-up spool includes a film guide that extends from the end of the film path toward the spool chamber. The film guide reliably guides the film, which has been led to the spool chamber, to the take-up spool. The film guide ensures that the film is properly wound on the take-up spool by preventing it from prematurely curling within the spool chamber. The film guide also ensures that magnetic recording operations performed on the film by a recording head, if present, are also reliably performed.
