Patent ID: 8739712

Claim:
A punch data generating device that generates punch data for execution with an embroiderable sewing machine, the embroiderable sewing machine including a needle bar that is configured to allow attachment of a punch needle for forming a plurality of small holes on a sheet of workpiece by piercing the workpiece in dot-by-dot strokes of the punch needle, and a transfer mechanism that is configured to transfer the workpiece in two predetermined directions in coordination with an up and down movement of the punch needle to execute a holing operation for forming the small holes on the workpiece, the punch data generating device, comprising: a cut data generator that generates cut data constituting the punch data, the cut data being configured to instruct consecutive formation of the small holes at least along an outline of a pattern section of the workpiece in which a predetermined pattern is drawn to allow cutting of the outline; a draw data generator that generates draw data constituting the punch data, the draw data being configured to instruct formation of the small holes on the pattern section of the workpiece to draw the predetermined pattern on the workpiece, wherein the cut data generator generates the cut data so as to instruct formation of the small holes on the workpiece at a first pitch and the draw data generator generates the draw data so as to instruct formation of the small holes at a second pitch, the first pitch being less than the second pitch.
