Image scanning system for copy machines

摘要

The apparatus disclosed herein is a copy machine wherein a document may be supported on a fixed plane and the image thereon scanned by a scanning mirror arranged to sweep past the document and by the use of a series of mirrors will position the image on a drum rotated on an axis parallel to the direction of movement of the scanning mirrors. This scanning system utilized a first and a second carriage which are moved relative to each other and are driven by a cam and linkage affording initially movement of the mirrors from a home position across the scanning area to a start position to begin the scanning mode at uniform speed, said cam affording continuous controlled acceleration, velocity and displacement of the scanning mirrors.
