1. An X-ray inspection device comprising:
a conveyor configured to convey an article;
an X-ray irradiation unit configured to irradiate the article conveyed by the conveyor with an X-ray;
an X-ray detection unit configured to detect the X-ray transmitted through the article;
an inspection unit configured to generate an X-ray transmission image from the X-ray detected by the X-ray detection unit and inspect the article on the basis of the X-ray transmission image;
a housing accommodating the X-ray irradiation unit and the X-ray detection unit;
a cool air blower configured to cool air inside the housing and guide cool air to the X-ray detection unit via a duct;
a monitoring unit configured to monitor a state of the cool air blower; and
a control unit configured to stop the flow of air to the X-ray detection unit when an anomaly of the cool air blower is detected by the monitoring unit.
