FIELD: imaging.
SUBSTANCE: light scanning module. The light source includes at least two light emitting points, with at least two light emitting points distributed along a straight line; the angle between the extension direction of their distribution line and the main scanning direction or the secondary scanning direction of the light scanning device includes an acute angle, wherein the main scanning direction is perpendicular to the secondary scanning direction. At least two light emitting points in the light source are distributed along a straight line, and the angle between the extension direction of the distribution line and the main scanning direction or the secondary scanning direction of the optical scanning device includes an acute angle, so that the distance between the light spots formed by the light beams emitted of at least two light emitting points incident on the scanned surface along the main scanning direction is enlarged.
EFFECT: avoidance of the occurrence of interference between light spots and improvement of image quality.
