ARTICLE SUPPORTING STRUCTURE |
摘要 |
A horizontal platform is shiftable sideways on an underlying carrier frame which in turn is horizontally shiftable on a stationary base at right angles to the platform movement on the carrier frame. A feed screw shifts the carrier frame back and forth on the base, and a friction wheel drive shifts the platform back and forth on the carrier frame.
