Claims

[Scope of utility model registration request]

A portion that is located near either side or one side of the aperture in the film wheel drive area and is located on the emulsion-coated side of the film, and that contacts the emulsion-coated side of the film when the film is stretched across the aperture. is a film transport roller that is displaced in a direction in which the emulsion-coated side of the film is inwardly curved; In a film flattening device for a camera, which is equipped with a bearing member for the transfer roller disposed on the side and a pressure plate that presses the film against the aperture during photographing, the film flatness is adjusted depending on the degree of curvature of the film. The film transport roller is elastically supported opposite to the film so that the position of the contact surface with the film changes, and the portion of the transport roller that contacts the film is displaced in a direction in which the emulsion coated side of the film curves inwards. 1. A film flattening device for a camera, characterized in that the stress distribution of the film is made uniform and the film is made flat with respect to the aperture surface by pressing the film with the pressure plate.
