SENSOR ARRANGEMENT WITH A PLURALITY OF SENSOR ELEMENTS, AN ELECTRONIC EVALUATION DEVICE, SELECTOR LINES BETWEEN THE SENSOR ELEMENTS AND THE ELECTRONIC EVALUATION DEVICE AND LOW-TRANSIENT-SIGNAL SWITCHING ELEMENTS IN THE SELECTOR LINES

摘要

The sensor arrangement (S) comprises a plurality of sensor elements (Sij), e.g., optical sensor lines with sensors made of amorphous, hydrogenated silicon, an electronic evaluation device (AE), selector lines (Aj) which connect each input (Ej) of the electronic evaluation device (AE) with at least one sensor element (Sij), and switch elements (SEij) in the selector lines (Aj) with which each sensor element (Sij) can be disconnected from the selector line (Aj). The switch elements (SEij) contain a photoelectric cell through which they can be controlled by incident light radiation. The sensor arrangement (S) can be used, for example, for telecopiers, facsimile machines and scanners for desktop publishing.
