Abstract: The present invention discloses a penta-mirror multi-reflection image scanning module including at least one light source, five reflecting mirrors, a pickup lens, an image sensor, and a frame. The reflecting mirrors reflect a light beam from a document and a plurality of reflecting mirrors reflect a light beam of the document twice or more to change the light beam direction along light path, and satisfy specific optical conditions. The total tracking length (TTL) may be adjusted through an arrangement of the distance of the five reflecting mirrors, but may not be adjusted through the angle of the five reflecting mirrors. Therefore, the present invention not only increases the field of depth by increasing the length of optical path in a limited space, but also facilitates the assembling to adapt to different tracking lengths.
