摘要： An optical scanning device deflects, by a common optical deflecting part, a plurality of groups of light beams emitted from a plurality of light sources and directs, by a scanning and imaging optical system, the groups of deflected light beams to respective scan surfaces so as to optically scan the scan surfaces. Each of the groups of light beams deflected by the optical deflecting part passes through at least two scanning lenses while being directed to a corresponding one of the scan surfaces. A first scanning lens arranged nearest to the optical deflecting part among the scanning lenses transmits the groups of light beams directed to the respective scan surfaces and satisfies Pm>0≧Ps, where Pm is a power in a main scanning direction and Ps is a power in a sub-scanning direction. A second scanning lens arranged nearest to the corresponding scan surface among the scanning lenses possesses a positive power in the sub-scanning direction and transmits only the group of light beams directed to the corresponding scan surface.

摘要： An optical scanner includes a light source, an optical coupler, an optical line image unit, a deflector, and an optical scanning unit. The optical scanning unit includes scanning lenses that guide the beams to a surface to be scanned. A surface on the deflector side of the scanning lens closest to a deflection reflecting surface has a negative power in a vertical scanning direction, and is a special toric surface in which a radius of curvature in a vertical scanning changes from an optical axis of the lens surface toward a periphery of the horizontal scanning direction. An F number of the beams toward the surface to be scanned of the scanning lens in the vertical scanning direction is larger in a peripheral part than in a central part in an effective scanning width.

摘要： An object of the present invention is to avoid such a problem that white dropouts and the Moire phenomenon occur in a filter-processed image. A filter unit employed in an image processing apparatus provided within a copying machine first selects as a pixel of interest any one of a plurality of reversed density pixels which constitute an image to be processed. Next, the filter unit uses density of this interest pixel before being corrected, density of pixels located at peripheral portions of this interest pixel, and a predetermined filter coefficient so as to calculate a weighted average value for each of the density. Finally, the filter unit compares the density of this interest pixel before being corrected with the weighted average values to output as a corrected density of this interest pixel, such a value approximated to a density equivalent to a black level. Furthermore, the filter unit compares the density of the interest pixel before being corrected with the predetermined reference density and, only when the density before being corrected is less than the reference density, it outputs the above-described weighted average value as the corrected density of this interest pixel irrespect to such a large/small relationship between the density before being corrected and the weighted average value.

摘要： In an a.c. generator for vehicles, an output terminal connected to a rectifier circuit unit has a seat surface on which an electric cable for connection with a storage battery is seated. The seat surface is positioned outside a rear cover and an insulating member in the longitudinal direction of the output terminal. The electric cable is tightened to the seat surface by a nut engaged with the output terminal, while holding the electric cable from contacting the insulating member. Thus, the insulating member is restricted from being deformed and the nut is restricted from loosening even when the insulating member contracts.
