56,448 ABSTRACT OF THE DISCLOSURE An improved facsimile machine having at least one edge emitting thin film electroluminescent line array, each array having a plurality of pixels wherein the pixels are selectively activated. A light beam from each pixel is directed to a known point along a line on a document and reflects to a sensor. The reflected beam corresponds to a grey level at the point of reflection on the document and causes the sensor to generate a signal corresponding to that greyness level. Sufficient pixels are provided to generate sufficient light beams to strike all points along a line across a document.
