Data processing system for sewing machine

A data processing system for a sewing machine, comprising:

• a needle adapted to be moved upward and downward;
• holding means for holding a material to be stitched;
• means for causing a relative movement between said needle and said holding means on the basis of a pattern data indicating a positional relationship therebetween;
• first memory means for storing a plurality of unit pattern data related to said relative movement for forming stitching patterns respectively;
• pattern selecting means for selecting unit pattern data from said first memory means;
• second memory means for storing said selected unit pattern data;
• manual designating means for designating a plurality of optional points on a desired curve and generating coordinate data related to said designated points;
• standard line determining means for determining a standard line which passes through said designated points based on said coordinate data;
• setting means for setting basic points of the selected stitching patterns stored in said second memory means so that said stitching patterns are individually positioned along said standard line;
• and
• means for rotating said unit pattern data around said basic points so that said stitching patterns are positioned in a direction substantially perpendicular to said standard line.

• first memory means for storing a plurality of unit pattern data related to said relative movement for forming a stitching pattern respectively;
• pattern selecting means for selecting unit pattern data from said first memory means;
• second memory means for storing said selected unit pattern data;
• designating means for designating a plurality of points on a desired curve;
• standard line determining means for determining a standard line passing through the plural points designated by said designating means;
• setting means for setting basic points of the selected stitching patterns stored in said second memory means so that said stitching patterns are individually positioned along said standard line;
• and
• mens for rotating said unit pattern data around said basic points so that said stitching patterns are positioned in a direction substantially perpendicular to said standard line, said setting means comprising means for setting gaps between the individual ones of said stitching patterns on the basis of the total length of said standard line and the total sum of the lengths of ranges along said standard a line of the individual ones of said stitching patterns.

A data processing system for a sewing machine, comprising:

• a needle adapted to be moved upward and downward;
• holding means for holding a material to be stitched;
• and
• means for causing a relative movement between said needle and said holding means in two axial directions intersecting each other in a horizontal plane, on the basis of a pattern data indicating a positional relationship therebetween,
• wherein the improvement comprises:
• first memory means for storing a plurality of unit pattern data related to said relative movement for forming stitching patterns respectively and a plurality of polygonal fundamental block data relative to said stitching pattern, fundamental blocks determined by said plurality of polygonal fundamental block data containing said stitching pattern determined by said unit pattern data therein;
• pattern selecting means for selecting unit pattern data from said first memory means;
• second memory means for storing said selected unit pattern data;
• manual designating means for designating a plurality of optional points on a desired curve and generating coordinate data related to said designated points;
• standard line determining means for determining a standard line which passes through said designated points based on said coordinate data;
• setting means for setting the starting points and end points of said fundamental blocks on said standard line on the basis of the fundamental data corresponding to the stitching pattern stored in said second memory means;
• and
• means for computing the angles, which segments joining said starting points and said end points form, and for rotating the individual ones of said pattern data.
