ABSTRACT:
An image consisting of a multitude of image points is formed by effecting relative transport between a plurality of light-emitting diodes and a recording medium. The diodes are arranged in rows. The rows are arranged successively in the transport direction. The rows extend at an angle relative to the transport direction. The diodes of each single row are offset relative to those of the other row, in direction transverse to the transport direction, by an amount equal to the distance between adjoining diodes in a single row divided by the number of rows, and/or multiples of that amount. Each diode is provided with an optical unit which projects onto the recording medium a reduced image of the light emitted by the diode. The diode-control signals corresponding to a single line of image points of the image to be formed are applied to the individual diodes with different respective time delays dependent upon the rate of transport and corresponding to the different distances among the rows as measured in the transport direction.
