Abstract
A beam head unit including beam heads configured to scan a single laser beam on a thin-film layer of a workpiece from an irradiation start side toward an irradiation end side in a direction crossing a feeding direction of the workpiece while the workpiece is fed by a constant-speed feeder; laser oscillator configured to emit the laser beam to irradiate each beam head; a controller configured to control scanning speed of the laser beam emitted from each beam head and feeding speed of the workpiece to control a machining line formed in the workpiece fed at the predetermined feeding speed. The controller is configured to switch a beam head to use to form the machining line between the beam heads to form the machining line alternately. This configuration makes it possible to form machining lines highly efficiently in the thin-film layer of the workpiece while feeding the workpiece.
