ABSTRACT:
A camera that reliably prevents frame shifts of film by inserting a frame shift prevention member into a film perforation is disclosed. The camera with a frame shift prevention function includes a frame shift prevention member that is supported to move toward or away from the perforation of the film. The frame shift prevention member includes a first oblique plane that makes contact with the edge of the perforation during feeding of the film in the direction of winding in preparation for shooting the next film and a second oblique plane that makes contact with the edge of the perforation during feeding of the film in the direction of reminding that are formed on the frame shift prevention member. The angle between the second oblique angle and the rewinding direction is smaller than the angle between the first oblique angle and the winding direction.
