Abstract
Work piece feeding machine capable of correctly and efficiently setting a work piece in a through-hole of a carrier. The machine includes a positioning unit which detects the amount of displacement of the work piece with respect to the through-hole and corrects the position of the work piece in the though-hole. The positioning unit includes: a lighting source provided on the work piece side or the carrier side and directing polarized light on the work piece and the carrier; a camera provided on the carrier side or the work piece side and receiving the polarized light from the lighting source so as to catch images of an out edge of the work piece and an inner edge of the through-hole in a visual field thereof; and an image processor which measures the amount of displacement on the basis of positions of the outer edge and the inner edge.
