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.
Claims13
A light beam scanner comprising:
- a light source;
- an optical deflector for repeatedly scanning a surface to be scanned in a series of scanning lines in a predetermined direction with a beam from said source, starting each scan at a desired time instant;
- means for moving said surface to be scanned in a linear direction substantially perpendicular to the direction of scanning lines formed on said surface;
- means movable with said surface and receiving a beam from said source for producing a signal whenever said surface to be scanned is moved a predetermined distance;
- and
- means for operating said optical deflector in synchronization with said signal.
