Abstract
A pattern-matching sewing machine that constantly samples photo-intensity data during calculation of a mismatch distance and during adjustment of the feeding mechanism based on the calculated mismatch distance. When the adjustment is finished, a new mismatch-distance calculation is quickly started, not by waiting for sampling new photo-intensity data of a predetermined number, but by using photo-intensity data of the predetermined number including the data thus sampled during the previous calculation and adjustment, and the previously stored data which have been used in the previous calculation.
