摘要： A multi-beam optical scanning apparatus including a light source including a plurality of radiation points disposed spaced from each other in a main scanning direction and in a sub-scanning direction, a rotational polygon minor for deflecting a plurality of light beams radiated from the radiation points, and an imaging optical system for imaging the plurality of light beams deflected by a deflecting facet of the rotational polygon mirror. The deflecting facet has a width in which a light beam reaching a farthest location from a center of the deflecting facet is eclipsed by an edge of the deflecting facet if emitted prior to a light beam from a second radiation point when controlled by auto-power-control. Control is performed such that the light beam from the second radiation point is radiated prior to the light beam from the first radiation point when controlled by the auto-power-control.

摘要： To obtain a positioning reference portion with good processing accuracy, which is formed of a newly-formed surface, a blank is press-molded by an upper mold, whereby a vertex portion abuts on an inner wall portion of a lower mold. In such a way, an oxide film that covers the vertex portion is broken by an internal pressure of the blank, and a raw material without oxide is moved by viscous flow from an inside thereof as illustrated by arrows. The raw material without oxide moved by viscous flow is thrust against the inner wall portion of the lower mold, whereby a newly-formed surface is formed, and this newly-formed surface serves as a positioning reference portion of an optical element. The newly-formed surface has surface roughness of the inner wall portion of the lower mold transferred thereto, and the positioning reference portion having good roughness is formed.

摘要： An optical scanning apparatus in which keystone distortion non-linearity distortion in a projected image can be excellently corrected is provided. An optical scanning apparatus has light source means and deflecting means for deflecting a light beam emitted from the light source means two-dimensionally in a first direction and a second directrion, the deflection speed of the deflecting means being higher in the first direction than in the second direction. The deflecting means is driven in such a way that its angular velocity in the second direction is smaller when optically scanning a position on the surface to be scanned at which the angle of incidence of the deflected light beam in the second direction is larger than when optically scanning a position on said surface to be scanned at which the angle of incidence of the deflected light beam in said second direction is small.

摘要： A two-dimensional scanning apparatus has light source means, deflecting means for deflecting a beam emitted from the light source means in a two-dimensional direction, and scanning optical means for directing the beam deflected by the deflecting means onto a surface to be scanned. The scanning optical means has one or more scanning optical element, and one or more surfaces of one or more of the aforementioned one or more scanning optical elements are anamorphic surfaces, and the anamorphic surfaces on the aforementioned one or more surfaces are anamorphic surfaces monotonously changing in a radius of curvature of which the absolute value of the radius of curvature in a first one-dimensional direction continuously decreases from one side toward the other side along a second one-dimensional direction orthogonal to the first one-dimensional direction. Thus, there can be supplied a two-dimensional scanning apparatus which can well correct TV distortion caused by the two-dimensional deflection of the beam by the deflecting means and trapezoid distortion caused by an image being obliquely projected onto a surface to be scanned, and a scanning type image displaying apparatus using the same.
