Abstract: An optical reflection panel made of thermosetting plastic material as a substrate is disclosed. One surface of the substrate is coated with an adherent layer and then an optical reflecting layer is formed on the adherent layer as a reflecting surface for reflecting a light beam. The other surface of the substrate is formed with a reinforcing structure. The reinforcing structure serves to increase the mechanical strength of the optical reflection panel and control the deformation amount. The reinforcing structure includes a number of reinforcing ribs extending along the longitudinal axis of the optical reflection panel and a number of reinforcing ribs perpendicular to the longitudinal axis of the optical reflection panel.

Abstract: An adjustable chassis for variable brightness for a scanner includes a light source, a reflection means, a lens, a charge coupled device and a brightness adjuster. The brightness adjuster may be a reflection mirror adjuster which can change the angle of a first reflection mirror, or a lamp holder adjuster which can change the light emitting angle toward the scanning document, or a light source adjuster which can change the distance between the light source and the scanning document so that brightness on the document may be obtained at an optimum degree to achieve better scanning quality.
