PROBLEM TO BE SOLVED: To provide a protective enclosure capable of reducing leakage of a laser beam.SOLUTION: There is provided a protective enclosure for enclosing an optical path of a laser beam emitted from laser equipment. The protective enclosure includes an incident opening part for allowing incidence of a laser beam emitted from the laser equipment and an emission opening part for allowing emission of the laser beam toward a conveyed irradiated body, and also includes leak prevention means for reducing intensity of the laser beam leaking from the protective enclosure.SELECTED DRAWING: Figure 3 |
