Abstract
A device for guiding a film in a cine camera comprises a channelled plate pierced with a window for filming and along the rear face of which is displaced the film. A presser member is disposed behind the film, opposite the filming window in the channelled plate, and means are provided for applying the presser member under pressure against the film and the channelled plate, when the film is stopped during filming, and for eliminating this pressure during the descending movement of the film. The means controlling the pressure exerted by the presser member on the film comprise a periodic magnetic field generator producing, during the descending movement of the film, a magnetic film acting on the presser member, made of ferromagnetic material, to eliminate the pressure of the presser member on the film during the descent thereof.
