えは好ましいものではなかった（第１図参照）。(Conventional technology) Conventional line drawing embroidery sewing methods using an embroidery sewing machine include straight line sewing or zigzag sewing along the contour of a motif (a method of sewing by oscillating a needle bar in a lateral direction and a method of reciprocating a cloth left and right). In particular, the zigzag stitching at the curved portion is dense on the inside of the curve (FIG. 1I) and coarse on the outside (FIG. 1O). The balance between the inside and the outside is lost, and furthermore, the seam overlaps on the inner side, so that thread breakage is likely to occur. Also, when the swing width (m) is considerably increased, the thread bulges and the embroidery is not preferable (No. (See FIG. 1).

In an automatic embroidery sewing machine provided with an upholstery frame sometimes supported so as to be able to move horizontally, and a control data storage section for storing control data for controlling the horizontal movement of the upholstery frame, a motif contour line is provided. The embroidery that is sewn by repeating the basic configuration continuously along is represented by D = log (n 1 × n 2 /m)/log(1/1.41×N 1 / a) Is approximately 1.

次に刺しゅう縫い方法について述べる。 Next, the embroidery sewing method will be described.
一般に相似比ｒが縮小してＮ個の部分に分解できる幾
何学的形状は下記の基本式（１）により非整数の次元Ｄ
をもつ。該次元Ｄが位相的次元よりも大きい場合フラク
タル図形と云われている。In general, a geometric shape whose similarity ratio r can be reduced and decomposed into N parts is a non-integer dimension D according to the following basic expression (1).
With. If the dimension D is larger than the topological dimension, it is called a fractal figure.
Ｄ＝logN/log（1/r）…基本式（１） 上記の概念をミシンによる縫い方法に当てはめると次
の式（２）となる（第２図参照）。D = logN / log (1 / r) Basic formula (1) When the above concept is applied to a sewing method using a sewing machine, the following formula (2) is obtained (see FIG. 2).
Ｄ＝log（２×ｎ×n2／N1）/logn…式（２） 但しn2：縫目の長さ N1：基本構成間の距離 n:N1の分割数 然し乍ら上記式（２）のD1はｎの値によって大きく変
化してしまうので、相似変換の見方を変えて前記式
（１）のＮに対しては線分の数n1、1/rに対しては糸の
太さａに対する２つの基本構成の間の距離N1を夫々当て
はめ、更に基本構成の各線分の長さが均一でないので重
みづけをして平均長さをn2、ジグザグ幅をｍとし、そし
て縮小率1/r＝１の場合にジクザグ縫をすれば縫い結果
は面となるから、ここで次元D1は点の場合にはD1＝０、
線の場合にはD1＝１、面の場合にはD1＝２であるから、
次元D1＝２となるように定数1/1.41を式に入れる。D = log (2 × n × n 2 / N 1 ) / logn Equation (2) where n 2 : stitch length N 1 : distance between basic structures n: number of divisions of N 1 However, the above equation (2) since D 1 of the) is greatly changes depending on the value of n, the formula by changing the view of the similarity transformation n against the yarn with respect to the number n 1, 1 / r of the line segment of (1) the distance n 1 between the two basic configurations for the thickness a each fitting, n 2 the average length and the weighted because not uniform more line segments of the length of the basic structure, the zigzag width is m, and If zigzag stitching is performed when the reduction ratio is 1 / r = 1, the sewing result will be a surface. Here, when the dimension D 1 is a point, D 1 = 0,
Since D 1 = 1 for a line and D 1 = 2 for a face,
The constant 1 / 1.41 is inserted into the equation so that the dimension D 1 = 2.
以上により上記基本式（１）は次のようになる。 As described above, the above-mentioned basic expression (1) becomes as follows.
D2＝log（n1×n2/m）/log（1/1.41×N1/a）…式（３） 上記式（３）のジグザグ縫（密着による）におけるD2
を求めると、N1＝2a、n1＝２、n2＝ｍであるから次のよ
うになる。D 2 = log (n 1 × n 2 /m)/log(1/1.41×N 1 /a)...Equation (3) D 2 in zigzag sewing (by close contact) of the above equation (3)
Is obtained, since N 1 = 2a, n 1 = 2, and n 2 = m, the following is obtained.
D2＝log（２×m/m）/log（1/1.41×2a/a）＝log2/log1.
41＝２ つまり２次元となり面として考えられる。D 2 = log (2 × m / m) / log (1 / 1.41 × 2a / a) = log2 / log1.
41 = 2 That is, it becomes two-dimensional and can be considered as a surface.
しかし現実には糸の太さ（ａ）、布の構造、模様の形
状等により曲線部にては縫が不可能となるから実験的に
得られる最良の縫い方法は次元がD2＝１であることが解
った。However, in actuality, it is impossible to sew at a curved portion due to the thickness (a) of the thread, the structure of the cloth, the shape of the pattern, and the like. Therefore, the best sewing method experimentally obtained has a dimension of D 2 = 1. I understand that there is.
次に本発明による実験例を以下に示す。 Next, an experimental example according to the present invention will be described below.
例1:第３図に示す線Ｃに沿って縫う場合 １−（１）:A部をN1＝10a＊とするとＤ＝0.26 Ｂ部をN1＝3aとするとＤ＝0.48 ＊印はＡ部を現実に縫うことの出来る最小の値である。Example 1: If sew along the line C shown in FIG. 3 1- (1): When the Part A and N 1 = 10a * D = 0.26 B unit is referred to as N 1 = 3a D = 0.48 * mark A This is the minimum value that can be used to actually sew the section.
１−（２）:A・Ｂ各部をN1＝10aとするとＤ＝0.26とな
り、上記１−（１）の例ではＡ・Ｂ各部間の差があるの
でバラツキが目立ち、上記１−（２）の例では次元Ｄが
１よりかなり小さくなるので模様の糸の密着度が低くな
るから直線部Ｂ部での面構成が良くないので刺しゅうと
しての出来栄えが悪くなる。1- (2): When N 1 = 10a for each part of A and B, D = 0.26. In the example of 1- (1), there is a difference between each part of A and B, so that the variation is conspicuous, and In the example of (1), since the dimension D is considerably smaller than 1, the degree of adhesion of the pattern thread is low, so that the surface configuration at the straight portion B is not good, and the performance as embroidery is poor.
例2:第４〜６図に示す夫々異なる種類の基本構成により
縫う場合 ２−（１）：第４図に示す基本構成では 仮にN1＝10a、n1＝８、n2/m＝1.2（図形からの計算値）
とすると、Ｄ＝0.85となる。従ってＤ＝１を得るために
はN1＝6.8aとすれば得られる。Example 2: Sewing with different types of basic configurations shown in FIGS. 4 to 6 2- (1): In the basic configuration shown in FIG. 4, tentatively N 1 = 10a, n 1 = 8, n 2 /m=1.2 (Calculated value from figure)
Then, D = 0.85. Therefore, in order to obtain D = 1, it is possible to obtain N 1 = 6.8a.
２−（２）：第５図に示す基本構成では 仮にN1＝10a、n1＝６、n2/m＝1.35（図形からの計算
値）とすると、Ｄ＝0.79となる。従ってＤ＝１を得るに
はN1＝5.7aとすれば得られる。2- (2): In the basic configuration shown in FIG. 5, if N 1 = 10a, n 1 = 6, and n 2 /m=1.35 (calculated value from the figure), D = 0.79. Therefore, D = 1 can be obtained by setting N 1 = 5.7a.
２−（３）：第６図の基本構成では 仮にN1＝5a、n1＝４、n2/m＝0.7（図形からの計算値）
とすると、Ｄ＝0.53となる。従ってＤ＝１にするにはN1
＝1.9aとすれば得られる。2- (3): In the basic configuration of FIG. 6, N 1 = 5a, n 1 = 4, n 2 /m=0.7 (calculated value from figure)
Then, D = 0.53. Therefore, to make D = 1, N 1
= 1.9a.
第４〜６図に示す各基本構成は単位構造であるが連続
性を有し、因みに第５図に示す基本構成の連続模様は第
７図に示す縫模様となる。第７図に示す数字１〜18は針
の順序を示すものである。Each of the basic structures shown in FIGS. 4 to 6 is a unit structure but has continuity, and the continuous pattern of the basic structure shown in FIG. 5 is a sewing pattern shown in FIG. Numerals 1 to 18 shown in FIG. 7 indicate the order of the hands.
以上により前記例２の各基本構成を利用して縫った刺
しゅうは特にＤ＝１となるように式（３）の各部n1、m2
/m、N1/aに各数値を入れて縫った刺しゅうが前記例１の
ジグザグ縫よりも縫目のバランスが保っているので安定
感を与えるものである。As described above, the embroidery sewn using the respective basic configurations of Example 2 described above is particularly applicable to the respective parts n 1 and m 2 of the equation (3) such that D = 1.
Embroidery sewn with each numerical value put in / m and N 1 / a gives a sense of stability since the stitches are more balanced than the zigzag stitches of Example 1.
