ABSTRACT:
An optical image reader is disclosed which effects the reading of an image on a given manuscript by moving a reading head provided with a plurality of photosensors over the surface of the manuscript and enabling the photosensors to directly discern the image information on the manuscript. In the optical image reader, the photosensors in the reading head are sequentially deviated in a direction perpendicular to the direction of the movement of the reading head and, therefore, are able to read the image information on the read points on the manuscript face to correspondingly deviated time intervals. Thus, the optical image reader operated at a high speed without any interruption.
