Abstract
A laser scanning apparatus includes a deflecting member such as a polygonal mirror for deflecting a laser beam, a lens holder for integrally holding a plurality of lenses, the plurality of lenses for transmitting the deflected laser beam, and a housing for accommodating at least the deflecting member. The lens holder is detachably mountable to the housing, whereby proper lens-to-lens positioning may be ensured during assembly and when the lens holder is detached, such as for lens cleaning, and subsequently remounted.
