摘要

PROBLEM TO BE SOLVED: To provide a stitch data structure for allowing a sewing machine to sew a stippling pattern.SOLUTION: A stitch data structure for sewing a stippling pattern in which projections 25 are formed so as to contact or nearly contact first points A1 to A7, and recesses 26 are formed so as to be spaced at a predetermined distance from first corresponding points a1 to a7 on a lower side reference line 77, and the recesses 26 are formed so as to be spaced at a predetermined distance from second points B1 to B4 on an upper side reference line 76, and the projections 25 are formed so as to contact or nearly contact second corresponding points b1 to b4 on the lower side reference line 77. In this manner, on the upper side reference line 76 and the lower side reference line 77 facing each other, the projections 25 and the recesses 26 are formed at the first points A and the first corresponding points a corresponding to each other, respectively, and the recess 26 and the projections 25 are formed at the second points B and the second corresponding points b corresponding to each other, respectively, so that curves bent in opposing directions to each other are formed at the corresponding points on the upper side reference line 76 and the lower side reference line 77.
