Abstract
In a laser beam scanner apparatus for scanning the surface of a photosensitive drum or a document to be read by deflecting a laser beam emitted from a laser diode with a deflector, there is provided a drive current control circuit for controlling the magnitude of drive current of said laser diode on the basis of a beam deflection angle of said deflector.
