PROBLEM TO BE SOLVED: To provide a manufacturing method of an optical scanner that, when using a common scanning lens for light sources having different wavelengths, can arrange the scanning lens at an optimal position according to the wavelengths of the light sources.SOLUTION: A manufacturing method of an optical scanner includes the steps of: selectively attaching, to a housing, either one of a plurality of types of light sources emitting light beams having different wavelengths and either one of a plurality of types of apertures according to a light source to be attached; attaching, to the housing, either one of a plurality of types of lens positioning jigs that can be selectively combined with the plurality of types of apertures; positioning and fixing a scanning lens to a predetermined position of the housing by using the lens positioning jig; and removing the lens positioning jig from the housing.SELECTED DRAWING: Figure 4 |
