Abstract
A photographic camera is adapted for use with a film cartridge having a tongue portion from which a curled film leader projects. The projecting leader comprises a relatively short full width section adjacent the tongue portion and a relatively long reduced width section separated from the tongue portion by the full width section. Integral means is provided in a loading chamber of the camera body for supporting the cartridge at its throat portion to locate the full width section of the leader away from the camera body during axial insertion of the cartridge initially into the loading chamber. This will prevent the forward longitudinal edge of the full width section of the leader from jamming against the camera body to interfere with film loading. A straightening member along the camera body contacts the forward longitudinal edge of the reduced width section of the leader to uncurl that section in response to continued axial insertion of the cartridge into the loading chamber.
