Abstract
A drum for a rotary scanner operable in both a transmissive and a reflective mode is manufactured to high concentricity yet relatively inexpensively by mounting an oversized (in thickness) drum blank of possibly varying diameter and thickness on a cylindrical mandrel and thereafter turning it on a lathe to the required external radius. End caps containing mounting means defining the effective scan axis are then secured to the drum for subsequent mounting in a rotary scanner.
