A tri-mirror multi-reflection optical path folding apparatus for optical scanner includes a light source, a reflection means, a lens set, a charged coupled device (CCD), and a base. The three reflection mirrors of the reflection means are positioned with each other at selected angles such that total reflection time of the optical path is four or five times. The optical path folding apparatus, consequently the scanner, can be made compact size, light weight and low cost.
