ABSTRACT:
A movable reflective panel is devised for an optical scanner to facilitate the scanning of a document from underside so that there is no need to place an opaque panel above the document. The optical scanner comprises a base housing having a transparent top, an upper housing pivotally mounted on the base housing above the transparent top, a scanning mechanism movably mounted within the base housing for scanning an image-bearing document positioned on the transparent top. The scanning mechanism comprises a light source for emitting light to the document from underside, an optical sensor for transforming light into corresponding electric signals, and optical means for transmitting light reflected from the document along a predetermined optical path to the optical sensor. The optical scanner further comprises a reflective panel movably mounted within the upper housing which moves in parallel with the scanning mechanism for reflecting light transmitted through the document back to the scanning mechanism along the optical path so as to enhance the light received by the optical sensor.
