An optical path folding apparatus for optical scanner includes a light source, a reflection means, a lens and a charged couple device (CCD). The light source provides light which is reflected by the reflection means to the lens for converging to form light image on the CCD. The reflection means constitutes at least three reflecting mirrors which has at least one double side reflecting mirror which in turn has a first and a second reflection surface. Light transmitted in the reflection means is reflected at least once on the first and second reflection surface respectively.
