Abstract
Abstract A method of setting visually balanced spacing between characters to be embroidered by an embroidering sewing machine in which character forming information which is stored with a preset reference size is successively read out and the characters are displayed and aligned between two parallel line segments. The aligned characters are first arranged in such a manner that the contours of consecutive characters contact each other at least at one point. Then the space areas between characters are calculated and a maximum area of the calculated space areas is set as a reference space area; then increasing the distances between the characters such that the other space areas between the characters become equal to the reference space area; and finally arranging the characters at spacings which have been increased by a computed minimum distance.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
108 words
A method for setting a space between selected characters to be embroidered by an embroidering sewing machine in which corresponding character forming information which is stored with a preset reference size is successively read out and displayed, comprising the steps of: individually, calculating space areas between characters when the characters are arranged in contact with each other; setting a maximum area of the calculated space areas as a reference space area; increasing the distance between characters delimiting the other space areas such that the other space areas become equal to the reference space area; and arranging the characters at spacings which have been increased by a minimum distance.
Claim 2
Independent Claim
108 words
A method for setting a space between selected characters to be embroidered by an embroidering sewing machine in which corresponding character forming information which is stored with a preset reference size is successively read out and displayed, comprising the steps of: individually, calculating space areas between characters when the characters are arranged in contact with each other; setting a maximum area of the calculated space areas as a reference space area; increasing the distance between characters delimiting the other space areas such that the other space areas become equal to the reference space area; and arranging the characters at spacings which have been increased by a minimum distance.
Claim 3
Dependent Claim
130 words
A method of setting spacing between selected characters to be embroidered by an embroidering sewing machine as defined in claim 1, in which the step of calculating the space areas between characters includes the steps of setting reference lines at substantially central positions of the characters, said lines being nornal to a direction of the character alignment; setting a plurality of contour specifying lines at spaced relationship, said contour specifying lines extending in the character alignment direction; calculating the distance information on the distance between a reference line and external contour of a character along the contour specifying lines; adding the information corresponding to the distance information at opposing sides of adjacent characters to obtain an added value; and calculating the space areas between characters by using the added value.
Claim 4
Dependent Claim
28 words
A method as defined in claim 1 wherein the minimum distance is determined as a quotient of the reference space area and a height factor of the characters.
Claim 5
Independent Claim
138 words
A method for setting a space between characters to be sewn by an embroidery sewing machine in which character forming information is stored with a preset reference size and characters to be sewn are successively read out, comprising the steps: (a) selecting a plurality of characters to be sewn; (b) arranging the selected characters in alignment between two parallel segment lines in such a manner that the adjacent contours of the characters are in contact with each other at least at one point to thereby provide space areas defined by the two parallel segment lines and the adjacent contours of the characters; (c) individually calculating the space areas between the characters; (d) setting a maximum area of the calculated space areas as a reference area; and (e) rearranging the characters with space areas corresponding to the reference area.
Claim 6
Independent Claim
138 words
A method for setting a space between characters to be sewn by an embroidery sewing machine in which character forming information is stored with a preset reference size and characters to be sewn are successively read out, comprising the steps: (a) selecting a plurality of characters to be sewn; (b) arranging the selected characters in alignment between two parallel segment lines in such a manner that the adjacent contours of the characters are in contact with each other at least at one point to thereby provide space areas defined by the two parallel segment lines and the adjacent contours of the characters; (c) individually calculating the space areas between the characters; (d) setting a maximum area of the calculated space areas as a reference area; and (e) rearranging the characters with space areas corresponding to the reference area.
Claim 7
Dependent Claim
143 words
The method as defined in claim 4 wherein the steps of individually calculating the space areas between the characters include the steps of: setting reference lines passing substantially through center portions of the adjacent characters respectively and being vertical to the two parallel segment lines; setting a plurality of spaced lines each perpendicular to the reference lines to thereby provide a plurality of sets of contour segments between the adjacent characters, extending from the reference lines to the adjacent contours of the adjacent characters; individually calculating a total length of each set of the contour segments; setting a maximum total length of the calculated total lengths; subtracting the calculated total length of each set of the contour segments from the maximum total length; and adding the differences between the maximum total length and each of the calculated total lengths to the reference area.
