ABSTRACT:
A stable, continuous, high-speed roll film media path is established between supply and take-up film reels. Supply and take-up path segments isolate a core transport path section from significant non-linear forces, thereby enabling continuous, high-speed, high-accuracy scan line imaging of the media. The supply and take-up path segments each operate to continuously maintain open decoupling loops in the film media while accurately controlling the speed, tension and alignment of the film media as transported through the core transport path section. A microcontroller operates two motor driven capstans to establish the film media speed and tension within the core transport path section. Optical sensors provide feedback to the microcontroller in managing two additional motor driven capstans to maintain the decoupling loops. The film media within the core transport path section is thereby isolated from frictive, inertial, and skewing forces that could otherwise degrade the media imaging.
