Abstract
An anagraphic stand comprises a base frame, a camera support structure and a mobile stage. The stage is driven relative to the camera by octhogonally-mounted linear drive means attached to the base and by a gear-reduced rotary drive means. All of the drive means are electronically converted microstepping devices and the drive structure is specially adapted to provide smooth, vibration-free motion.
