FOREIGN MATTER DETECTING DEVICE AND PARTS FEEDER

摘要

PROBLEM TO BE SOLVED: To provide a foreign matter detecting device for detecting the presence of a foreign matter on a transport passage.SOLUTION: An imaging section 3 stores images obtained by simultaneously irradiating a predetermined region of a transport floor surface Y2 with light from a first light source 1 and a second light source 2 having different beams and angles of incidence different from each other. Image input means inputs the images. A first image based on the first light source 1 and a second image based on the second light source 2 are extracted from the input images. An image of a workpiece is determined on the basis of the first image. A region corresponding to the image of the workpiece determined in the first image is removed from the second image. An image having a predetermined area or larger is determined to be an image of a foreign matter on the basis of the second image from which the image of the workpiece has been removed.
