照射装置。[Scope of Claim for Utility Model Registration] A base material in which vertical magnetization magnetic poles facing each other are provided around the irradiation window of a vacuum chamber equipped with an electron beam source inside, and a magnetic paint is coated on the surface. In an electron beam irradiation device that transports a tape between the magnetic poles and vertically magnetizes and hardens the magnetic paint by an electron beam passing through the irradiation window, the lower magnetic pole of the magnetic poles is exposed to the electron beam. A beam catcher for protection is installed so that its surface coincides with the center line between the magnetic poles, and the base tape is brought into sliding contact with the surface of the beam catcher to transport the electron. Line irradiation device.
