Abstract
For the line-by-line optical scanning of a film as it passes at high speed through a scanning region, particularly to obtain television image signals, a light source directs light to a sensor. To reduce friction of the film adjacent the scanning region, two rollers or endless belts support the film at positions on the film outside the film frames. These rollers or belts replace the previously usual stationary film guide shoes adjacent the film gate. Lateral guidance of the film can be provided by rollers.
