An apparatus which can function either in a copier mode or in a raster scan mode. A first unit of the apparatus, containing elements to produce an information modulated, scanning light beam, is movably mounted upon a second unit of the apparatus, containing optical elements for directing light upon a photosensitive medium, such that the movable unit can be located clear of the document supporting platen of the second unit to provide copier operation or can be located immediately adjacent the platen of the second unit to provide raster scanning operation. Optical means are provided in the movable unit to provide light focusing capabilities for the raster scan mode of operation.
