Abstract
An optical beam scanning system has a multibeam control mechanism (4) with a beam interval adjusting mechanism for adjusting an interval between beam spots on a recording surface. The mechanism has at least one plane parallel plate (471-474). The plate is placed on an optical path. The plate is turned on an axis which is perpendicular to the optical path to thereby change the interval while maintaining the diameter of the beam spots on the recording surface. A pair of prisms may be installed in place of the plane parallel plate. The prisms are relatively moved in a parallel manner to thereby change the interval while maintaining the diameter of the beam spots.
