PURPOSE:To allow the smooth delivery of a film to the outside of a cartridge body without flawing the film by inclining at least either of a pair of flanges with a spool and partially forming the spacing larger than the film width between a pair of the flanges, then discharging the film. CONSTITUTION:A pair of the flanges 5a, 5b which regulate the loosening of the film 2 are provided on the spool 3 and at least one 5a of the flanges 5a, 5b rotates integrally with the spool 3. In addition, the flanges 5a, 5b are consti tuted freely inclinably with the spool 3 so as to partially form the spacing larger than the film width with the other flange 5b. At least the one flange 5a, therefore, rotates together with the spool 3 and the rotating force thereof is transmitted to the film 2. The flange 5a inclines to form the spacing larger than the width of the film 2 between this flange and the other flange 5b at the time of delivering the front end 2a of the film and, therefore, the film 2 is smoothly delivered from this spacing toward a discharge port. The housed roll film is surely delivered to the outside without flawing the film in this way.
