Abstract
A light guide device includes a first light guide part, a polygon mirror, a second light guide part, and an adjustment part. The first part reflects and guides a laser light emitted from a laser generator. The polygon mirror has a reflective part which reflects the light guided by the first part while the reflective part rotates. The second part reflects the light reflected at the reflective part and directs the light so that the light is illuminated to the workpiece at each reflective part, respectively. The adjustment part adjusts the position of the light incident on the polygon mirror in the rotation axis direction of the optical axis, thereby changing the positions of light incident on the irradiation target in the line width direction. The irradiation target is irradiated with the light while the position of the light in a line width direction.
