Embroidery stitch data producing device and sewing machine

A device for producing embroidery stitch data for an apparatus having a vertically reciprocating needle, a thread catching means cooperating with the needle to catch the needle thread to form stitches on a work to be stitched, a work holding means for holding the work and a mechanism for moving the work holding means in the X-Y directions relative to the needle, said device comprising:

• pattern data supplying means for supplying pattern data including stitch data for a plurality of different patterns, and indication data for indicating said patterns;
• pattern selecting means operated to select a desired one or ones from said plurality of patterns;
• display means for indicating the selected pattern or patterns thereat;
• pattern positioning means operated to optionally set the position or positions of the selected pattern or patterns;
• discrimination means for discriminating if said selected and positionally set patterns are wholly received in a predetermined stitch area where said work holding means is movable;
• and
• data modifying means for modifying the stitch data of the patterns in reference to reference points which are specific to the patterns respectively if the discrimination means discriminates that said selected and positionally set patterns are wholly received in said stitch area.

• pattern data supplying means for supplying pattern data including at least stitch data for a plurality of different patterns, data for indicating said patterns, data for indicating reference marks defining the relative positions and angles between said patterns;
• pattern selecting means operated to select a desired one or ones from said plurality of patterns;
• pattern positioning means operated to optionally set the position or positions of the selected pattern or patterns;
• calculating means for calculating the distance between said patterns defined by said reference marks;
• display means for indicating thereat the selected patterns and the calculated distance therebetween.

• pattern data supplying means for supplying pattern data including at least stitch data for a plurality of different patterns, indication data for indicating said patterns, reference mark data for reference marks defining the positions and angles of the pattern relative to the work holding means to which the work is attached;
• pattern selecting means operated to select a desired one or ones from said plurality of patterns;
• pattern positioning means operated to optionally set the position or positions of a selected pattern or patterns;
• and
• print data producing means for producing print data for printing said selected and positionally set pattern or patterns in the actual size thereof to be stitched and said reference marks.
