X-ray device

Abstract

An X-ray device includes a conveying unit, an X-ray irradiation unit, an X-ray detection unit, and a control unit. The conveying unit is configured to convey an article. The X-ray irradiation unit is configured to irradiate the article being conveyed by the conveying unit with X-rays. The X-ray detection unit is configured to detect the X-rays in a detection region within which the article is conveyed. The control unit is configured to compare a detection value from the X-ray detection unit and a threshold value to sense a front end and a rear end of the article in a conveying direction. The control unit is configured to switch the threshold value from a first threshold value to a second threshold value after the front end of the article has passed through the detection region and before the rear end of the article passes through the detection region.
