Abstract: An embroidery sewing machine calculates the number of designs to be used for sewing for a length that is closest to a desired sewing length, based on the desired sewing length and information regarding the designs. The embroidery sewing machine calculates the sewing length based on the calculated number of designs and the information regarding the designs. Furthermore, the embroidery sewing machine adjusts the length of each design such that the calculated sewing length matches the desired sewing length, and converts the adjusted data of the designs into embroidery data. This enables sewing such that the sewing start and end points match each other or junction matching is secured, even in a case of sewing in the form of various kinds of combinations of curves and lines or the like. In addition, this provides an embroidery sewing machine that is capable of executing sewing with an improved appearance.
