Appearance inspection method for goods

An appearance inspection method for goods, the method being for performing appearance inspection on a to-be-inspected object by using an appearance inspection device including:

• a planar tray having a plurality of transparent pockets in which a plurality of the respective to-be-inspected objects are placed away from each other, each of the pockets having a support which, when the corresponding to-be-inspected object is placed in the pocket, supports the to-be-inspected object through contact with the to-be-inspected object so as to extend along an outer periphery of the to-be-inspected object;
• a plurality of first cameras disposed away from each other on a front surface side and a back surface side of the planar tray, the first cameras being capable of collectively and simultaneously imaging the plurality of to-be-inspected objects from the front surface side and the back surface side of the tray;
• and
• a second camera capable of imaging the plurality of to-be-inspected objects from side surfaces of the planar tray other than the front surface and the back surface, wherein
• the pockets of the tray are formed in a grid pattern as seen from the front surface side, and the to-be-inspected objects are arranged such that one of the to-be-inspected objects is placed per specific longitudinal direction or lateral direction of the pockets in the grid pattern and such that only one of the to-be-inspected objects is placed in a same direction as seen from any of the side surfaces, and
• the plurality of to-be-inspected objects are imaged from the front surface side and the back surface side of the tray by the first cameras and are imaged from the side surfaces by the second camera such that the to-be-inspected objects are simultaneously imaged and inspected from the front surface, the back surface, and the side surfaces of the tray.
