摘要： A chassis for mounting components in a photographic film scanning apparatus cabinet includes a planar base member, and bearing mounts integral with the base member. The mounts sized and configured to hold bearings against which an arcuate wear plate of a gate of the scanning apparatus registers. The gate is configured to move in a pendulum-like manner across the bearings, with an aperture in the planar member for rotatably accommodating a shaft of a drive system for moving the gate in the pendulum-like manner. Mounts integral with the planar base member are provided for holding an optical system of the scanning apparatus. A continuous integral rib is arranged on the rear surface of the planar member is tuned to a higher natural frequency than that of the scanning frequency for vibrationally isolating the planar base member from other components in the cabinet.
