装置。[Claims for Utility Model Registration] A laser oscillator that is composed of a mirror and a laser rod and emits a laser beam, a beam expander that is composed of an input lens section and an output lens section that collimates the laser beam, and an output beam from the beam expander. a beam shaping unit that shapes the beam into a desired shape; a glass mask having a character pattern that fits into the desired shape; and an optical means that images the shaped pattern light that has passed through the glass mask onto the surface to be processed. In a laser marking device, at least one of the entrance lens section and the exit lens section includes a rotary plate on which at least two lenses with different magnifications are mounted equidistantly from the center; A laser marking device comprising: a rotational drive mechanism that rotates a desired lens among the lenses so that it is switchably positioned within the laser beam.
