摘要：
A scanning device for scanning a flat scanned surface by means of a rotating or rotatively vibrating deflector. The scanning device is provided with a rotational asymmetric image forming optical system disposed between the deflector and the scanned surface for forming an image of the scanned surface at a substantially equal distance from the deflecting surface of the deflector in the plane defined by the path of movement of the normal to the deflecting surface of the deflector in accordance with the rotation thereof.
