    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.

    Abstract: A contact image sensor comprises a housing, a light source provided on the upper part of the housing to irradiate light to a document, lenses arranged in the housing and provided at least on an entering side and an outgoing side to focus reflected light from a reading position of the document, an aperture angle regulation member having an inclined surface to reflect a part of light irradiated from the light source at the reading position of the document and an aperture portion into which the reflected light enters directly to regulate an aperture angle to permit the reflected light passing through the aperture portion to be irradiated to the lens on the entering side, and a light receiving element array to receive and photoelectrically convert the reflected light focused after passing through the lenses.
