Optical device for scanners, has concave mirrors with reflecting surface to focus and reflect light to predetermined route, stop on light traveling route between image device and mirror rejects extra light

摘要

The device has concave mirrors (170, 190) with a reflecting surface to focus and reflect light to a pre-determined route. An image device (86) accepts the light reflected from a mirror and converts the light into a digital signal. A stop (80) is on the light traveling route between image device and a mirror to reject extra light. An image-adjusting module (87) adjusts the image formed by the mirror. An Independent claim is also included for an image adjusting method.
