Patent ID: 7282726

Claim:
An electron beam irradiation apparatus comprising: a turn-transfer mechanism configured to transfer an irradiation target; a turn-transfer chamber in which the turn-transfer mechanism is disposed; an electron beam irradiation section disposed at a part of the turn-transfer chamber, and configured to irradiate the irradiation target with an electron beam while the irradiation target is rotated; a replacement room disposed at a part of the turn-transfer chamber, and configured to bring the irradiation target into and out of the turn-transfer chamber; an outer irradiation target holding table disposed outside the turn-transfer chamber, configured to form a part of the replacement room, and including an X-ray shielding mechanism, an airtightness maintaining mechanism, and an irradiation target holding mechanism; an inner irradiation target holding table disposed inside the turn-transfer chamber, configured to form a part of the replacement room, and including an X-ray shielding mechanism, an airtightness maintaining mechanism, and an irradiation target holding mechanism, the inner irradiation target holding table being supported by the turn-transfer mechanism; a turning mechanism configured to turn the turn-transfer mechanism and an elevator mechanism configured to move the turn-transfer mechanism up and down; and a rotation mechanism disposed at the electron beam irradiation section and configured to rotate the irradiation target.
