Abstract
261,275. Debrie, A. L. V. C. May 11, 1926. Kinematograph apparatus.- In a camera, a single rotary movement of the film guide displaces the film from the exposure position and substitutes a focusing screen. The film guide 5 having an exposure aperture 6 may be carried by a rotary circular plate 4 carrying a focusing screen 7. The plate 4 may turn within a ring 2, or about a pivot. The feeding claws may be freed from the film before rotation, or may move with the plate 4.
