Abstract

Abstract In an easy loading camera comprising a film magazine receiving chamber formed in the camera body on one side of the film aperture and shaped to permit insertion of a film magazine having a film leader thereinto in one axial direction of the film magazine, and a film leader guiding means for guiding the film leader in between the film aperture and a pressure plate from one longitudinal edge thereof when the magazine is inserted into the chamber, there are provided first and second edge limiting members. The first edge limiting member is disposed in the camera body to abut against said one longitudinal edge of the film leader to limit its position in the transverse direction thereof when the film leader is introduced into the space between the film aperture and the pressure plate. The second edge limiting member is mounted on the back lid of the camera body so as to abut against the other longitudinal edge of the film leader to limit its position in the transverse direction thereof when the back lid is closed.
