  • Patent number: 10713775
    Abstract: An item inspection apparatus includes an image obtaining section and a control section. The image obtaining section obtains a captured image of at least a part of an item. The control section determines whether the item is defective by using the captured image of the item. The control section performs a first inspection for at least one of position, shape and size with respect to at least one of a first element and a second element. The first element has a predetermined shape and is formed on the item and the second element includes at least one of an opening, a depression and a through-hole formed in the item. The control section performs a second inspection for at least one of foreign substance adhesion, scratch and surface stain on the item. Thus, the defect inspection may be performed more precisely and effectively.
