ABSTRACT:
An image is formed on a recording medium by illuminating a multitude of points on the surface of the recording medium to form lines of image points. Relative movement is effected between the recording medium and a plurality of light-emitting diodes. The light-emitting diodes are arranged in a plurality of rows. Each row extends parallel to the direction in which a line of image points to be formed upon the recording medium extends. The rows are arranged successively in the direction of relative movement. A plurality of projector lenses is operative for projecting reduced-scale images of the light emitted by the light-emitting elements of the plurality of rows onto a portion of the recording medium on which a single line of image points is to be formed. The projector lenses are arranged in a plurality of lens rows, each of which extends parallel to the direction of the line of image points to be formed. The lenses of each row project the light emitted by the elements of only a single respective one of the rows of light-emitting elements. Successive lenses within each lens row project onto the recording-medium line images of the light emitted by successive respective groups of the light-emitting elements of the associated row of light-emitting elements.
