Abstract

An alternative to existing Raster Output Scanning (ROS) devices is provided which eliminates moving components and the requirement for precision alignments attending current ROS devices. In addition, the use of solid state input eliminates the cost of components required by scanners of the CRT type.

An alternative to existing Raster Output Scanning (ROS) devices is provided which eliminates moving components and the requirement for precision alignments attending current ROS devices. In addition, the use of solid state input eliminates the cost of components required by scanners of the CRT type.

Referring to the figure, the photoreceptor 5 of a xerographic system is exposed via a matrix 6 of solid state Light Emitting Diodes (LEOs) 7. LEOs 7 are selectively activated in accordance with video image signals applied thereto through X and Y leads 8, 9 from a suitable source of image data, i.e., a raster input scanner. A lens block 10 has a corresponding series of lens elements 11 mounted therein, there being one lens element 11 associated with each LED 7. Individual fiber optic cables 12 are used to optically couple each lens element 11 with a generally rectangular exposure block 14 spaced opposite to and extending across the width of photoreceptor 5.
