Abstract

In the arrangement shown in Figure 1, a xerographic image is scanned by a line scanning beam 6. Beam 6 is derived from a laser 7 which (following suitable processing by optical section 8) is scanned across the surface of photoreceptor 5 for a suitable scanning element such as a rotating polygon 9. Light reflected from the surface of photoreceptor 5 is collected by an integrating cavity I1 and converted to image signals by photodetector 12. As a result, an input image scanner using components from an existing copy machine is provided.
