Abstract:
1. An apparatus used for active energy beam irradiation, comprising: an irradiating chamber for irradiating a target object with an active energy beam, the irradiating chamber including a transport inlet for transporting the target object into the irradiating chamber and a transport outlet for transporting the target object out of the irradiating chamber; an irradiating apparatus for irradiating the target object with the active energy beam within the irradiating chamber; and a gas supply mechanism for supplying one of an inert gas and a reactive gas into the irradiating chamber to thereby set up one of an inert gas atmosphere and a reactive gas atmosphere within the irradiating chamber, wherein the irradiating chamber includes an irradiating section for irradiating the target object with the active energy beam emitted from the irradiating apparatus, and a transport duct having a gas flow resistor to set up a condition of X/Y≧1, where X represents a gas amount passing through the transport inlet and Y represents a gas amount passing through the transport outlet, wherein the transport duct includes a transport roll and a roll cover at least partially covering the transport roll, both arranged on a first side of one of a front surface and a back surface of the target object passing through the transport duct, and wherein the gas flow resistor is arranged on a second side, wherein the gas flow resistor comprises one of: at least one partition wall, a cover arranged to conform with the shape of the transport roll and covering the target object and the transport roll, and a nip roll and a roll cover covering the nip roll.
