Patent

CA 2066748

A film scanner is disclosed which comprises a dynamic film gate (11). The film gate (11) includes a pair of capstans (12) for supporting the film (16) at an imaging station (18) and a pair of belts (20) which clamp the film against the capstans. The cap- stans (12) are driven to advance the film through the imaging station (18). An integrating cylinder (41), located between the cap- stans (12), produces a line of light on the film (16), and light transmitted through the film is imaged onto a linear CCD image sen- sor (23). In order to provide a more efficient drive mechanism for the capstans (12), the drive shaft (17) for the capstans (12) is incorporated in the integrating cylinder (41).
