Abstract: Parallel laser beams #1, #2 and #3 produced by splitting one laser beam into three, are introduced to an optical scanning device (2) along the central axis of a recording cylinder (24), the optical scanning device being disposed on the central axis of the recording cylinder and rotated thereabout, having an inclined mirror surface (4), the recording cylinder holding a recording sheet (S) on an interior surface thereof. The laser beam #2 incident upon the mirror surface at its center of rotation is reflected at the point of incidence, while the laser beams #1 and #3 are deflected by acousto-optical devices (10X, 14X) back and forth in the opposite directions in synchronism with the rotation of the optical scanning device, in parallel planes held at a distance and including the laser beams #1 and #3 therein, thereby to give the laser beams #1 and #3 angles of incidence upon the mirror surface necessary in order for the laser beams #1, #2 and #3 after reflected to produce scanned loci running parallel to each other at a given interval on the recording sheet, regardless of rotational positions of the optical scanning device. To adjust a relative difference in the lengths of the scanned loci, timing at which the laser beams #1, #2 and #3 are turned on/off is controlled. When the laser beams #1 and #3 are deflected so as to gyrate along a conical plane whose central axis is that of the recording cylinder, the laser beams #1, #2 and #3 produce scanned loci always running parallel to each other at a given interval with the same scanning lengths on the recording sheet.

Abstract: An optical scanner includes a light source modulated based on image data, an optical deflection and scanning part deflecting a light beam emitted from the light source, and a scanning and imaging optical system condensing the deflected light beam toward a scanning surface so as to form a light spot optically scanning the scanning surface. The effective scanning region of the scanning surface is divided into a plurality of regions according to a scanning line curving characteristic. Suitable image data for optically scanning the divided regions are selected from image data of a plurality of image lines every time the light spot optically scans the effective scanning region, so that the image data of each of the image lines is written with scanning line curving being corrected.
