Abstract

Present Raster Input Scanners (RIS) employ a Charge Coupled Device (CCD) for scanning a document line by line, the CCD providing a sequential digital output of image signals representing the document image. A lens is used to collect and minify the image line to CCD length, and mirrors are provided to guide the image rays from the document to the CCD via the lens, the mirrors serving additionally to provide a small package configuration.
