LASER MARKING APPARATUS

摘要

In a laser marking apparatus having a laser beam ramifying unit adapted to ramifying in a time sharing manner a laser beam sent out from one laser oscillator into a plurality of laser beams advancing on a plurality of different optical paths, and a plurality of marking units for scanning an upper surface of a required stamped pattern-displayed liquid crystal mask with the ramified laser beams from the laser beam ramifying unit and marking a work with the laser beam passed through the liquid crystal mask, the laser beam ramifying unit is provided with a means for condensing the laser beam from the laser oscillator, a means for ramifying in a time sharing manner the laser beam condensed by the condensation means into laser beams advancing on a plurality of different optical paths, and a plurality of means for guiding the beams from the laser beam ramifying means into the marking units, so as to enable the pitch of optical fibers to be reduced, the switching of object to which the ramified laser beams are to be applied to be done at a high speed, and the density of fiber bundles arranged in a space to be improved.
