Abstract

The object of the proposed design is to eliminate a moving optical scanner, for example a laser beam. Its place is taken by a single row (3) of electro-luminescent diodes. The raw length corresponds to the size of image to be copied. The spacing of the diodes corresponds to the number of dots required on the reproduction to give the image quality needed. In a practical application the luminescent diode strip (3) is connected to a corresponding photodiode reading strip (4). This reads the picture (6) on the original (5) to be copied. The output of the diode strip (3) alters the charge on the sensitised surface (2) of a revolving drum (1). The rest of the process is conventional. The luminescent strip can be made as a monolithic block. Reproducing speeds are approx. 0.5 microsecond per line.
