Abstract
A film scanner is disclosed which comprises a dynamic film gate. The film gate includes a pair of capstans for supporting the film at an imaging station and a pair of belts which clamp the film against the capstans. The capstans are driven to advance the film through the imaging station. An integrating cylinder, located between the capstans, 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 provide a more efficient drive mechanism for the capstans, the drive shaft for the capstans is incorporated in the integrating cylinder.
