ABSTRACT:
A sewing machine of the invention stores width dimensions and the reference needle penetration position dimensions, which all can be changed for writing and reading, according to the type of presser foot, in a memory. Based on the needle penetration position and the reference needle penetration position which are determined when the seam allowance width is set, the sewing machine calculates a distance between the left or right end of the presser foot and the position where stitches are made, and shows it on the display as the seam allowance width. Therefore, sewing can be made regarding the distance from the left or right end of the presser foot to the place where stitching is made as a seam allowance width, just by aligning the edge of the work cloth with the left or right end of the presser foot.
