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.
