Abstract
In a multibeam scanning optical apparatus of a type where two parallel lines are simultaneously scanned by two laser beams irradiated from two semiconductor lasers, stable images are formed on the scanned surface by the two laser beams and the cost is reduced. The two laser beams irradiated from the two semiconductor lasers are directed substantially in the same direction through a beam splitter and then shaped by a condenser lens into two luminous fluxes whose optical axes are substantially parallel to each other. In another arrangement, the semiconductor lasers are directly secured to a surface of the beam splitter by use of an ultraviolet setting resin.
