Claims

[Scope of utility model registration request]

On the periphery, there are a large number of letters and symbols 9a and 9b with holes at equal intervals in the circumferential direction, and one hole 10a,
A plurality of stencils 6a, 6b provided with stencils 10b are arranged coaxially so that the position provided with the above-mentioned characters etc. is located within the beam path of the laser beam from the laser oscillator 1, and each stencil 6a, 6
servo motors 7a, 7b having encoders 8a, 8b are connected to b, and each of the above stencils 6a
, 6b, a galvano-scanner mirror 12 that reflects the laser beam and a concave arc-shaped reflection mirror 13 that reflects the reflected laser beam from the galvano-scanner mirror 12 toward the workpiece 14 are provided in the beam path on the downstream side of the galvano-scanner mirror 12. Furthermore, the servo motors 7a, 7 are provided.
