ABSTRACT:
A scanning clock generating device for an optical scanner which scans a selected surface by a light beam to write optical information or read image information. The scanner scans the surface by a light beam which is deflected at a constant or a non-constant angular velocity and without resorting to an F-theta lens. The scanning clock generating device generates a scanning clock the frequency of which is continuously variable responsive to changes of scanning velocity on the surface to be scanned.
