Abstract
An apparatus for recording an image with a plurality of laser beams on a recording surface comprises a plurality of laser source units each generating a laser beam and a first lens for directing the laser beam from each one of the plurality of laser source units to the recording surface. In the apparatus, the laser source units are each disposed on a holding member in such a manner that the principal ray of the laser beam therefrom passes through a front focal point of the first lens. Thus, the apparatus is advantageous in that it is not necessary to employ an enlarged lens despite increase in the number of the laser source units, or the channel numbers.
