发明名称 STABILIZING DEVICE FOR SURFACE OF LOADED FILM IN CAMERA
摘要 PURPOSE:To improve the flatness of a photographic film which has dispersed magnetic material powder, by attracting this film to a film pressure plate which has an attractive surface of a magnet during photography. CONSTITUTION:A photographic film F1 is exclusively used. A normal film is formed of only a photosensitive film 3 made of an emulsion layer and an antihalation film on the surface of a film base 2 and another antihalation film 4 on the reverse surface, although this film F1, in addition, has magnetic material powder dispersed in the film base 2. When this film F1 is loaded in a camera equipped with a film pressure plate 14 consisting of two flat plates 14a and 14b of magnetic materials, the film F1 at a photographic position is attracted to the film pressure plate to fix the position of the film, so that its flatness is increased, obtaining an excellent picture.
