摘要： In an optical scanning device using two polygon mirrors, the present invention achieves both a simplification of the device and a reduction of vibrations. An optical scanning device is provided with a first optical system including a polygon mirror and a second optical system including a polygon mirror. The polygon mirror provided in the first optical system and the polygon mirror provided in the second optical system are configured such that they rotate in mutually opposite directions. Further, the optical scanning device is provided with one BD sensor for detecting laser beams that are scanned with the polygon mirrors. Slits with mutually different widths are arranged between the BD sensor and the respective polygon mirrors of the first and second optical systems.

摘要： In an overfilled optical scanner in which a plurality of light beams are used, a uniform luminous-energy distribution is achieved on a scanning plane to be scanned. The optical scanner includes: a light source 3 for producing a first light beam L1 and a second light beam L2; a polygon mirror; a first image formation optical system for leading the light beams L1 and L2 to a deflecting plane of the polygon mirror and for forming, on the deflecting plane, a line image whose width is greater than the plane width of the deflecting plane; and a second image formation optical system for leading the light beams L1 and L2 from the polygon mirror to the scanning plane of a photosensitive drum and forming an image on the scanning plane. The first image formation optical system is adjusted so that the optical axes A1 and A2 of the first and second light beams L1 and L2 are approximately symmetrical about the optical axis A0 of the first image formation optical system. The powers of the first and second light beams L1 and L2 are thus balanced with each other on the scanning plane.

摘要： A reflector 10 is formed so as to have a long side along a scanning direction of a ray bundle. The reflector 10 includes a thin-plate-shaped reflector body having one plane to be a reflection plane 20 and upper and lower ribs 21a and 21b each extending from the reflector body in a back side. The reflector plane 20 is formed of a curved plane having positive power at least in the scanning direction, i.e., a so called free-form plane. The reflector 10 is supported by protrusions 31, 32 and 33 at three points, i.e., first, second and third support points S1, S2 and S3 located in the vicinities of one end portion of the reflector, the other end of thereof, and a center portion thereof, respectively. A distance L1 between an imaginary straight line V1 joining the first and second support points S1 and S2 and the third support point S3 is larger than a sag L2 of the reflector 20. The center of gravity G of the reflector is located inside of an imaginary triangle V3 joining the first, second and third support points S1, S2 and S3.

摘要： By a first image forming optical system (42a to 42d), a plurality of light beams from light sources (41a to 41d) form linear images on a common deflecting surface (46) of an optical deflector (44). Light beams reflected off the optical deflector (44) are reflected by a plurality of curved surface mirrors (45a to 45d) and are allowed to scan over photosensitive members (4a to 4d), respectively. The plurality of curved surface mirrors (45a to 45d) are disposed on the same side with respect to a plane that includes a normal line at a center of the deflecting surface (46) and is parallel to a main scanning direction. Further, curved surfaces of the plurality of curved surface mirrors (45a to 45d) vary in shape. Thus, a tandem type color image forming apparatus that achieves low cost and has excellent optical performance and an optical scanning device that is used favorably in the color image forming apparatus can be provided.

摘要： Defect inspection of repeated pattern on a surface is executed by reducing influence of a base layer. Thus, surface-inspecting apparatus and method include unit irradiating repeated pattern on specimen's surface with illuminating light, units setting an angle formed by direction on an incidence plane's surface including irradiating direction of illuminating light and a normal to the surface and repeated direction of repeated pattern to predetermined value except zero, a light detecting unit detecting regular reflected light from repeated pattern when illuminating light is irradiated and outputs information about light intensity of regular reflected light, and a detecting unit detecting the repeated pattern's defect on information, from light detecting unit. Additionally, an angle formed by the direction on incidence plane's surface and repeated direction, an angle formed by irradiating direction of illuminating light and normal to surface, a wavelength of illuminating light, and a pitch of repeated pattern satisfy conditional expression.
