摘要： A light scanning device has a light deflector for deflecting in a scanning mode a light beam outputted by a light source; and an optical system for image-forming on a scanning medium the light beam deflected by the light deflecting means, with a convergent or divergent light beam in an optical path between the light source and the scanning medium. A plane-parallel plate is moved into and out of the optical path of the convergent or divergent light beam, so as to change a beam spot diameter on the scanning medium.

摘要： In a laser printer wherein a photoconductive drum is scanned by utilizing a plurality of laser beams, there are detected spacings between the plural laser beams, such detection being confined to a blanking time. On the basis of the detected results, the spacings between the plural laser beams are controlled; and this state is maintained for a printing time. With this arrangement, it is possible to accurately detect the spacings between the plural laser beams thereby to obtain the practicable laser printer employing the plural laser beams.

摘要： Electric-photosensitive printing is accomplished with an LD providing a laser scanning beam that is modulated to affect printing, and the power output of the LED is maintained constant through negative feedback by a holding voltage provided by a capacitor having its charge determined only during a non-printing portion of the printing period wherein a plurality of sheets are printed. During the non-printing period, contact of the scanning laser beam with the electro-photosensitive material is disabled while the laser beam is maintained on so that its power may be measured and compared with a reference level to provide a feedback signal for controlling the output of the laser beam, particularly the feedback signal being provided to the holding capacitor only during the non-printing portion of the period, and the holding capacitor being isolated from the feedback signal during the printing portion of the period. As a specific embodiment, a rectangular sheet of electric-photosensitive material is replaceable wound around a drum so that its opposite ends are spaced apart to provide a seam to affect the disablement of the laser beam from contracting the electro-photosensitive material during the non-printing portion of the period, and a separate light source used to detect this seam portion to determine the non-printing portion of the period.

摘要： A light scanning device has a light deflector for deflecting a light beam in a scanning mode which is outputted by a light source, and a scanning lens for compensating or reducing an amount of shift in scanning position which is due to the error of the light deflector. The device also forms an image of the light beam thus deflected. At least one surface of the scanning lens is non-arcuate when a section is taken with a plane which is perpendicular to the surface scanned with the light beam and which contains the normal of the section taken with the surface. Owing to this construction, the light scanning device is suitable for a high precision laser printer.

摘要： A laser scanner which includes a rotary polyhedral mirror for scanning a light beam from a laser light source, and an F.theta. lens system which includes first and second lenses through which the light beam is radiated onto a scanning plane. The first lens of the F.theta. lens system is provided on the rotary polyhedral mirror side and is constructed with a joined lens, to increase the degree of design of the first lens. This design freedom for the F.theta. lens system improves the F.theta. characteristic (i.e., characteristic of displacement on a scanning plane), the field curvature characteristic (i.e., characteristic of image defocusing on the scanning plane) and similar problems.

摘要： An optical scanner and method in which light beams from a plurality of sources are directed onto a medium to form a composite spot. The relative positions of the beams are detected and changed to change the diameter of the composite spot so that lines formed by such spots appear unbroken. The modulating times, intensities and number of sources of the beams can also be varied to provide a linear relation between the dither matrix and the picture element density.

摘要： In a laser beam scanning apparatus, first and second laser beam emitters emit a laser beam polarized in a specific direction and a laser beam polarized in the direction orthogonal with this specific direction. A prism passes a laser beam emitted from the first laser beam emitter but reflects a laser beam emitted from the second laser beam emitter, and amalgamates two laser beams emitted from the first and second laser beam emitters in almost the same direction. A rotating polygonal mirror and a scanning lens simultaneously scan on a scanned plane two laser beams amalgamated by the prism. A 1/4 wavelength plate is inserted between the rotating polygonal mirror and the prism to change the laser beam from the prism from a linearly polarized state to a circularly polarized state. By the above arrangement, a difference of reflection factors between two laser beams incident to the rotating polygonal mirror can be eliminated so that two uniform laser beams can be scanned at the same time.

摘要： An optical scanning apparatus has a scanning lens with a rotationally asymmetric aspheric surface having individual curvature radii in the main scanning direction and in the sub-scanning direction. The curvature radius in the sub-scanning direction is asymmetrically increased in the lateral direction with the distance from the optical axis. A field curvature aberration which may be generated in the sub-scanning direction on the scanning surface due to an oblique incident of optical beams on the rotating polygonal mirror or the movement of the reflective surface caused by rotation of the rotating polygonal mirror is compensated for by the scanning lens and the focusing properties of the system can be kept at a level of high resolving power.
