APPARATUS FOR LASER PROCESSING A LIGHT GUIDE PLATE AND HAVING CONSTANT LIGHT PATH DISTANCE OF A LASER BEAM

摘要

The present invention relates to an apparatus for laser processing a light guide plate in which the light path is constantly maintained to provide a light guide plate having high quality. The apparatus includes a plurality of reflection mirrors for reflecting the laser beam and a block for path correction transferred in the direction in which the light path distance decreases when the laser irradiator is transferred in the direction in which the light path distance increases. At least one of the plurality of reflection mirrors is disposed on the block for path correction to maintain a constant light path distance for the traveling laser beam on the whole.
