ABSTRACT:
An automatic film processor for passing an exposed film successively through developing, fixing and rinsing stations to effect continuous development thereof. The film is applied with ultrasonic vibrations as it moves through the treating liquids to accelerate the treating speed, the ultrasonic vibrations being applied to the film such that the surface of the film is not perpendicular to the direction along which the ultrasonic wave has its maximum directivity. Arrangements for further promoting the effect by the application of ultrasonic vibrations are also provided. By the combined use of the application of ultrasonic vibration and preheating of the film, processing speed is further increased. Preheating of the film is controlled depending on the integrated amount of the already processed film, the density of the developed image or the feed rate or moving speed of the film.
