Paper Abstract

Image reading techniques for high speed, high resolution document scanners were studied. The study covered high-speed line scanning using charge coupled device (CCD) image sensors, high intensity illumination system, improvement of modulation transfer function (MTF) of scanning optical system, and reliable document handling mechanism. This paper also discusses a document scanner made to demonstrate the study results. The scanner read documents at 1 second per document and 11.8 picture elements per millimeter (pels/mm) of resolution, and had more than 0.5 of the MTF. A newly developed document feed mechanism reduced the feed error rate to less than 0.05% and assured a document throughput of 60 pages/min.
