Abstract
An optical apparatus for scanning an original in a copying machine or the like is disclosed. In the apparatus, a scanning mirror for scanning the original and a stationary mirror for reflecting an image of the original from the scanning mirror in a direction nearly normal to the scanned surface constitute a first optical path. The stationary mirror and a lens for receiving the reflected light from the stationary mirror and focusing the original image on a photosensitive element constitute a second optical path. During scanning of the original by the scanning mirror, the distance between the scanning mirror and the lens and the distance between the lens and the photosensitive element are kept constant.
