ARTICLE INSPECTION APPARATUS AND ARTICLE INSPECTION METHOD

An article inspection apparatus inspects a workpiece W including a plurality of ingredients Wa, Wb, Wc, and Wd by using an inspection image of the workpiece. The article inspection apparatus includes an X-ray image memory 61 that stores information of a predetermined detection value related to the inspection image, a configuration determination unit 53 that determines a material configuration of a content in the workpiece W by performing predetermined recognition processing based on image data of the workpiece W obtained by capturing of the camera 41, and a proposal output unit 54 that, when the configuration determination unit 53 determines the material configuration of the content, estimates detection sensitivity to the predetermined detection value based on information stored in the X-ray image memory 61 and a management sensitivity memory 64, and proposes and outputs a determination criterion for an article inspection.
