Abstract
Disclosed is an improved transport mechanism for cyclically conveying an original past an optical scanning device in an electrophotographic copying machine of the type in which a gripping unit engages a leading edge of an original during the entire cycling time, which reduces distortion, maximizes utilization of the transport mechanism, and enables the use of lower illumination intensities by optically scanning the original as a planar surface and by providing a pair of transport rollers downstream of the optical scanning device to insure a fast cycling and delivery of the original.
