METHOD AND DEVICE FOR IRRADIATING ACTIVE ENERGY RAY

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for irradiating an active energy ray to an object to be irradiated when an atmosphere of an inert gas is needed for the irradiation in an irradiation chamber. SOLUTION: The object to be irradiated 8 is carried in from a carrying entrance, irradiated with the active energy ray 9 under the atmosphere of the inert gas in an active energy ray irradiation part 1, and carried out from a carrying exit. An airflow resistance at the carrying entrance is controlled in a way that X/Y>=1 if an air volume passing at the carrying entrance = X and an air volume passing at the carrying exit = Y.
