One of a second plurality of other work pieces is positioned in registration with one of the positioning targets and a detecting mechanism provided with the detectors is rotated about a prescribed reference position. Then another positioning target on the first work piece is detected by means of the detecting mechanism, so that the positions Of the plurality of second work pieces will be brought into registration with the plurality of positioning targets on the first work piece.
