Abstract
A light beam scanner having an optical deflector which can repeatedly scan one surface to be scanned in a predetermined direction with a light beam and can start each scan at a desired time instant. A drive mechanism moves the surface to be scanned, in a direction substantially perpendicular to the direction of scanning lines formed on said surface. A signal is outputted whenever the surface to be scanned is moved a predetermined distance and a mechanism is employed for operating the optical deflector in synchronization with the output signal.
