Embroidery sewing machine, thread color grouping method, and program

A thread color grouping method employed in an apparatus comprising:

• a thread color storage unit that stores thread colors to be sewn in a sewing order for each of a plurality of designs to be sewn;
• a thread color comparison unit;
• and a thread color grouping unit, the thread color grouping method comprising:
• a first step in which the thread color comparison unit judges whether or not a thread color of a comparison target is the same as a thread color of a comparison reference;
• and
• a second step in which the thread color grouping unit groups the comparison target with the comparison reference when they are the same color,
• wherein:
• the comparison target is a portion having a design and a thread color;
• and
• the comparison reference is another portion that differs from the comparison target and has a design and a threat color, the design and the threat color of the comparison reference being stored in the thread color storage unit, and
• wherein, in the second step, when the thread color comparison unit has judged that the comparison target is the same as the comparison reference, the thread color storage unit stores information such that the comparison target is to be sewn together with the comparison reference that has been judged to be the same, and the sewing data for the comparison target is removed.

A non-transitory recording medium that records a program for instructing a computer to execute a thread color grouping method employed in an apparatus comprising:

• a thread color storage unit that stores thread colors to be sewn in a sewing order for each of a plurality of designs to be sewn;
• a thread color comparison unit;
• and a thread color grouping unit,
• wherein the thread color grouping method comprises:
• a first step in which the thread color comparison unit judges whether or not a thread color of a comparison target is the same as a thread color of a comparison reference;
• and
• a second step in which the thread color grouping unit groups the comparison target with the comparison reference when they are the same color,
• wherein:
• the comparison target is a portion having a design and a thread color;
• and the comparison reference is another portion that differs from the comparison target and has a design and a threat color, the design and the threat color of the comparison reference being stored in the thread color storage unit, and
