Abstract
An apparatus for optically writing information comprises a row of longitudinally spaced LED array chips, a photosensitive surface arranged to face the chip row in parallel thereto, and a lens system arranged between the chip row and the photosensitive surface. Each array chip has constantly spaced LEDs to provide luminescent dots. The lens system includes convex lens elements arranged in corresponding relation to the respective array chips to form magnified images, in inverted arrangement, of the luminescent dots of the respective array chips on the photosensitive surface, so that all of the dot images on the photosensitive surface are constantly spaced.
