Abstract
An arc-segment-shaped gate for a photographic film scanning apparatus has a six inch radius from a pivot shaft of the gate to the outermost surface at which the scanning of the film is to occur. The gate is pivoted around a pivot axis through an optical chassis of the scanning apparatus and is driven by a worm-gear segment arrangement via a reversible electric motor. The gate swings through an arc of approximately 61/2.degree. on each side of a vertical initializing position of the gate and has an aperture at which a frame of the film can be held against the gate by a clamping arrangement which is moved with the gate. The gate of the present invention is that the gate is mounted to be adjusted about a spherical bearing by the use of bearings mounted on eccentric shafts against which a wear plate on the gate is registered. Pins and biasing springs mounted on the gate and the gate system drive allow adjustment of the gate in .THETA. X and .THETA. Z directions for obtaining precise optical alignment.
