Embroidery data processing apparatus and process of producing an embroidery product
First Claim
1. An apparatus for processing embroidery data needed to control a sewing machine to form an embroidery pattern on a work sheet, the apparatus comprising:
- an outline-data memory which stores original-outline data representing at least one original outline of an original embroidery pattern, said original outline including a plurality of segments;
a reference-vector memory which stores data indicative of a reference vector specifying a reference direction and a reference length; and
shadow-pattern embroidery-data producing means for producing, based on said original-outline data and said reference vector, shadow-pattern embroidery data needed to control the sewing machine to form stitches of at least one shadow embroidery pattern which is contiguous with the original embroidery pattern and whose outline is defined by at least one of said segments of said original outline and at least one of two straight width-defining segments which extend in said reference direction from opposite two ends of said one segment, respectively, and each of which has said reference length defining a width of the shadow embroidery pattern in said reference direction.

Abstract
An apparatus for processing embroidery data needed to control a sewing machine to form an embroidery pattern on a work sheet, the apparatus including an outline-data memory which stores original-outline data representing at least one original outline of an original embroidery pattern, the original outline including a plurality of segments, a reference-vector memory which stores data indicative of a reference vector specifying a reference direction and a reference length, and a shadow-pattern embroidery-data producing device for producing, based on the original-outline data and the reference vector, shadow-pattern embroidery data needed to control the sewing machine to form stitches of at least one shadow embroidery pattern which is contiguous with the original embroidery pattern and whose outline is defined by at least one of the segments of the original outline and at least one of two straight width-defining segments which extend in the reference direction from opposite two ends of the one segment, respectively, and each of which has the reference length defining a width of the shadow embroidery pattern in the reference direction.

21. A process of producing an embroidery product by forming an embroidery pattern on a work sheet, the process comprising the steps of:
-
producing, based on original-outline data representing at least one original outline of an original embroidery pattern, and data indicative of a reference vector specifying a reference direction and a reference length, shadowed-pattern embroidery data needed to control a sewing machine to form stitches of a shadowed embroidery pattern including the original embroidery pattern and at least one shadow embroidery pattern which is contiguous with the original embroidery pattern and whose outline is defined by at least one of a plurality of segments of said original outline and at least one of two straight width-defining segments which extend in said reference direction from opposite two ends of said one segment, respectively, and each of which has said reference length defining a width of the shadow embroidery pattern in said reference direction; and operating a computer of the sewing machine to control, according to the produced shadowed-pattern embroidery data, a stitch-forming device of the sewing machine to form the stitches of the shadowed embroidery pattern on the work sheet and thereby produce the embroidery product. - View Dependent Claims (22, 23, 24)

25. A recording medium in which an embroidery-control program is recorded which is readable by a computer and usable to control the computer to process embroidery data according to which a sewing machine forms an embroidery pattern on a work sheet, the program comprising steps of:
-
obtaining original-outline data representing at least one original outline of an original embroidery pattern, said original outline including a plurality of segments; obtaining data indicative of a reference vector specifying a reference direction and a reference length; and producing, based on said original-outline data and said reference vector, shadow-pattern embroidery data according to which the sewing machine forms stitches of at least one shadow embroidery pattern which is contiguous with the original embroidery pattern and whose outline is defined by at least one of said segments of said original outline and at least one of two straight width-defining segments which extend in said reference direction from opposite two ends of said one segment, respectively, and each of which has said reference length defining a width of the shadow embroidery pattern in said reference direction. - View Dependent Claims (26, 27, 28, 29, 30)
