<P>PROBLEM TO BE SOLVED: To efficiently assemble a scanning optical device. <P>SOLUTION: The method comprises: an inspection step in which focal depth ends in a main scanning direction and a sub-scanning direction of a scanning lens are obtained by inspecting the scanning lens; an adjustable amount arithmetic step in which adjustable amounts Zml, Zmu, Zsl and Zsu are calculated from the focal depth ends obtained by the inspection step for the focal depth ends; an adjustment amount determining step (S6) in which if Zml<Zmu, Zsl<Zsu, maxäZml, Zsl}<minäZmu, Zsu} are all satisfied, an adjustment amount Scp in an optical axis direction of a coupling lens is determined in the range of maxäZml, Zsl} to minäZmu, Zsu}; and fitting steps (S7 to S9) in which the scanning lens inspected in the inspection step is fitted to a housing, the position of the coupling lens in the optical axis direction is determined according to the adjustment amount Scp determined by the adjustment amount determining step, and the coupling lens is fitted to the housing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
