A film scanner is disclosed which comprises a dynamic film gate. The gate includes a pair of rollers for supporting the film at an imaging station and a pair of drive belts which clamp the film against the rollers. The belts are driven to advance the film through the imaging station. An integrating cylinder located above the film gate produces a line of light on the film, and light transmitted through the film in imaged onto a linear CCD image sensor. In order to insure that the end of the film is held flat at the imaging station, movable guides are provided to selectively engage the film adjacent the line of light on the film.
