Optical write head, and method of assembling the same

摘要

In an optical write head, a rod lens array, a substrate support member for supporting a substrate, and a driver circuit board are fixedly held by a support member. The support member and the substrate support member are formed from metallic material, and a frame of the rod lens array is formed from a glass plate. Further, distance between a light-emitting section of a light-emitting device array and a light-incident end face of the rod lens array is adjusted, by means of rotating eccentric pins. Further, light-emitting device array chips are die-bonded on the substrate bonded at predetermined positions on the substrate support member while the position of the substrate support member is taken as a reference plane.
