X-ray inspection apparatus

An X-ray inspection apparatus comprising:

• a conveying unit configured to convey an article;
• an irradiation unit configured to irradiate the article conveyed by the conveying unit with an electromagnetic wave;
• a detection unit configured to detect the electromagnetic wave emitted from the irradiation unit and transmitted through the article;
• an inspection unit configured to inspect the article based on a detection result of the detection unit;
• and
• a determination unit configured to determine attachment of the conveying unit, wherein
• the conveying unit includes first and second conveying units arranged side by side with a passing region through which the electromagnetic wave from the irradiation unit to the detection unit passes therebetween, and
• the determination unit includes:
• a support portion attached to the first conveying unit;
• a swing member swingably attached to the second conveying unit and at least partially in contact with the support portion when the first and second conveying units are attached;
• and
• a switch configured to detect whether the swing member is present at a predetermined position in a state where the swing member is in contact with the support portion.
