Document Type and Number:
Japanese Patent JP7199996
Kind Code:
B2
Abstract:
To provide an X-ray inspection device in which friction resistance received by an inspected object when passing through a shield curtain is small, and a package of a product is hardly damaged.SOLUTION: An X-ray inspection device 1 has: a housing 2; transportation means 3; an X-ray irradiation unit 4; an X-ray detection unit 5; and a shield curtain 10 whose upper end is supported by a support shaft 11 (Fig.1). On an upstream side of a lower end of the shield curtain, a roller 15 is rotatably provided via a roller shaft 16. When an inspected object being transported pushes the shield curtain, the shield curtain is lifted up as the lower end oscillates toward a downstream side and the inspected object passes through the lower end of the shield curtain and moves to the downstream. The roller of the shield curtain rolls along a front surface of the inspected object. Friction resistance between the inspected object and the roller is small and a package of the inspected object is hardly damaged.SELECTED DRAWING: Figure 3
