Claims

[Scope of Claim for Utility Model Registration] (1) A laser beam adjustment jig used in a laser processing machine when cutting vulcanized rubber 3 using a laser beam 1, the laser beam adjustment jig being used in a laser processing machine. a conduit 5 provided on the oscillation side of the laser beam and guiding the laser beam 1; a ring-shaped member 6 provided on the opening side of the conduit 5; and a ring-shaped member 6 closer to the vulcanized rubber 3 than the ring-shaped member 6. The ring-shaped member 6 and the condenser lens 2 are arranged such that their centers coincide with the optical axis of the laser beam 1, and The shaped member 6 has a central hole whose size corresponds to the polymer decomposition region a of the laser beam 1, which consists of a portion corresponding to the polymer decomposition region a and a portion corresponding to the polymer decomposition process region b. A laser beam adjustment jig characterized in that the size is such that only a corresponding portion of the laser beam 1' passes through. (2) The ring-shaped member 6 has a polished upper surface,
2. The laser beam adjusting jig according to claim 1, wherein the laser beam adjusting jig is adapted to reflect the laser beam corresponding to the region b of the polymer decomposition process in the laser beam 1.
