Abstract

The figure shows a system which scans an original document without the standard linearly moving platen or scanning optics configuration. A document to be copied is placed in the pocket 12 afixed to the surface of transparent flexible mylar web 14 .Web 14 is entrained about a pair of drive rollers 16,18. In a single copy mode, web 14 is rotated in a clockwise direction until the leadin edge of the pocket is sensed by registration sensor 20. At this point,

The figure shows a system which scans an original document without the standard linearly moving platen or scanning optics configuration. A document to be copied is placed in the pocket 12 afixed to the surface of transparent flexible mylar web 14 .Web 14 is entrained about a pair of drive rollers 16,18. In a single copy mode, web 14 is rotated in a clockwise direction until the leadin edge of the pocket is sensed by registration sensor 20. At this point,

14 is slowed down and syncronized with the speed of photoreceptor drum 22

As the document inserted in pocket 12 moves through illurnination zone 24, lamp 25 is enerszed and an incremental image is reflected and projected by a linear short focal length lens 26 onto the drum surface. After the entire document has passed through the illumination zone, it IS removed from the pocket which has now been returned to its initial position.

For multiple copy runs, after the entire document has passed through the illumination zone, a second sensor 28 generates a signal to change the speed of web 14 and quickly returns it to the repstration point.
