Abstract
A laser drawing apparatus is provided including a splitting means for splitting laser light emitted from a laser source into at least two groups of drawing beams, the beams of each group being aligned in a common plane; a scanning means for scanning a drawing surface with said at least two groups of drawing beams in a main scanning direction; a first adjusting means for rotating the common plane, in which one of the at least two bundles of drawing beams are aligned, about an axis extending parallel to the drawing beams; a second adjusting means for moving at least one of the at least two groups of drawing beams in said main scanning direction of the scanning means; and, a third adjusting means for moving at least one of the at least two groups of drawing beams in a sub-scanning direction perpendicular to the main scanning direction.
