In order to solve the above-mentioned problem, the present invention uses one circle having a radius in the range of 80.0 mm to 500.0 mm as a base circle, is concentric with the base circle and the base circle, and has a larger radius than the base circle. Among the intersections of small circles and a group of centerlines with a constant central angle in the range of 0.1 to 5.0 degrees, the radius is the largest from the intersection that is the starting point on the base circle A basic figure that connects a line segment connecting a selected intersection point and a basic figure connecting a circular arc to a point of intersection on a basic circle via a circle or a small circle is a connected chain .

  By using the present invention, it is possible to easily draw a cutting line on the cloth based on the sewing line on the pattern, and to correct the pattern by enlarging or reducing the sewing line to a desired size. You can also. Then, it is possible to make a fold or the like on the cloth, or to mark stitches such as applique or quilting. Also, the present invention can be used in the same way when working on paper or the like.

  By using the present invention, it is possible to make a pattern with sewing lines and cutting lines, or to make a pattern with a plurality of sewing lines so that the sewing lines can be selected according to the size. It becomes easy, and a pattern sheet for sewing can be made as well.

  In addition, since the present invention can be manufactured in various shapes, the shape can be selected according to the application.

  Although the size of the present invention is not particularly defined, for convenience of explanation, an example in which a synthetic resin sheet is cut out based on a figure drawn with a central angle in the range of a maximum of about 65.0 degrees is described here. The details will be described below.

  Example 1 is an auxiliary tool for drawing a cutting line of 5.0 mm or 10.0 mm which is generally used based on a sewing line of a pattern, and is shown in FIG. FIG. 2 is a diagram for explaining how to draw the original form of the first embodiment. As shown in FIG. 2, the first embodiment uses a base circle 1 having a radius of 125.0 mm and a circle concentric with the base circle 1 as a floor circle, and a floor circle having a radius of 130.0 mm and a floor circle having a radius of 150.0 mm. Up to 2e, a group of floor circles whose radius increases at intervals of 5.0 mm, and a floor circle 3a with a radius of 120.0 mm to a floor circle 3e with a radius of 100.0 mm, the radius decreases at intervals of 5.0 mm. The original figure which connected the basic figure drawn by connecting the line segment connecting the selected intersection among the intersections of the floor circle group and the center line group having a central angle of 1.25 degrees. Based on.

  In order to make the explanation of FIG. 2 easier to understand, the intersection point to be selected will be represented by the coordinates of the center line and the circle. A certain intersection on the basic circle 1 is selected as the starting point for drawing the first basic figure, the coordinates are represented as (0, 1), the center line passing through the first intersection rightward from the starting point and the floor circle 2a The coordinates of the intersection point are represented by (1, 2a), and the coordinates of the intersection point of the center line passing through the second intersection point from the start point to the left and the floor circle 3c are represented by (-2, 3c). A procedure for drawing the original drawing of the first embodiment according to this notation will be described. First, draw the upper side of the original drawing. When the intersections to be selected for drawing the first basic figure on the upper side are sequentially listed, the intersection 4 (0, 1), the intersection (1, 2a), the intersection (-1, 2c), the intersection (1, 2c), the intersection ( −1, 2e), intersection (1, 2e), intersection (2, 2d), intersection (3, 2e), intersection (5, 2e), intersection (3, 2c), intersection (5, 2c), intersection ( 3, 2a), intersection (4, 1), intersection (5, 2a), intersection (7, 2a), and intersection 5 (8, 1). Then, using the intersection 5 (8, 1) as the starting point of the next basic figure, the drawing of the basic figure is repeated in the same manner, and the upper part of the original drawing can be drawn by drawing to the intersection 6 (4, 1) which is the final point. Next, the lower side is drawn in the direction opposite to the upper side. In order to balance the figure, in the upper coordinate display, the starting point (0, 1) of the basic figure that draws the second left intersection 7 (-2, 1) of the intersection 4 (0, 1) below The intersection points to be selected for drawing the first basic figure on the lower side are sequentially enumerated, and the intersection point 7 (0, 1), the intersection point (1, 3a), the intersection point (-1, 3c), the intersection point (1, 3c) ), Intersection (-1, 3e), intersection (1, 3e), intersection (2, 3d), intersection (3, 3e), intersection (5, 3e), intersection (3, 3c), intersection (5, 3c) ), Intersection point (3, 3a), intersection point (4, 1), intersection point (5, 2a), intersection point (7, 3a), intersection point 8 (8, 1). Then, repeating the drawing of the lower basic figure in the same manner with the intersection 8 (8, 1) as the starting point of the next basic figure, and drawing up to the intersection 9 (4, 1) which is the final point, the lower part of the original figure I can draw. Then, the intersection 4 and the intersection 7 which are the first starting points on the upper side and the lower side are connected, and further, the intersection 6 and the intersection 9 which are the final points of each are connected, and the closed figure which is the original form of the first embodiment can be drawn.

  In Example 1, the original shape drawn in this way was transferred to a polypropylene sheet having a thickness of 0.3 mm and cut out with a knife or the like. When Example 1 is used, it is possible to draw a seam allowance having a width of 5.0 mm or 10.0 mm on a pattern or fabric. Further, when it is desired to change the size to be sewn, it is possible to draw a sewing line that increases or decreases the size by a width of 5.0 mm or 10.0 mm.

  When the second embodiment is used when sewing an object smaller than the first embodiment in handicraft or the like, it is possible to draw a copied figure with a finer mark. Since the figure which shows the shape of Example 2 was shown in FIG. 3 for demonstrating how to draw the original form, it abbreviate | omitted. As shown in FIG. 3, the second embodiment uses a base circle 1 having a radius of 110.0 mm and a circle concentric with the base circle 1 as a floor circle, and a floor circle having a radius of 115.0 mm and a floor circle having a radius of 135.0 mm. Floor circles with a radius increasing at intervals of 5.0 mm up to 2e and floor circles with a radius decreasing at intervals of 5.0 mm from a floor circle 3a with a radius of 105.0 mm to a floor circle 3b with a radius of 100.0 mm Based on the original drawing that connected the basic figures drawn by connecting the line segments connecting the selected intersections of the intersections with the center line group having the center angle of 0.625 degrees. .

  In order to make the explanation of FIG. 3 easy to understand, the intersection point to be selected will be represented by the coordinates of the center line and the circle. A certain intersection point on the basic circle 1 is selected as the starting point for drawing the first basic figure, the coordinates are represented as (0, 1), the center line passing through the second intersection point to the right from the starting point, and the floor circle 2a The coordinates of the intersection point are represented as (2, 2a), and the coordinates of the intersection point between the center line passing through the fourth intersection point in the right direction from the start point and the floor circle 3b are represented as (4, 3b). A procedure for drawing the original drawing of the second embodiment according to this notation will be described. First, draw the upper side of the original drawing. When the intersections to be selected for drawing the first basic figure on the upper side are sequentially listed, the intersection point 4 (0, 1), the intersection point (2, 2a), the intersection point (2, 2b), the intersection point (4, 2b), the intersection point (4 , 1), intersection (6, 2a), intersection (6, 2b), intersection (2, 2c), intersection (6, 2c), intersection (2, 2d), intersection (6, 2d), intersection (2, 2e), intersection (8, 2e), intersection 5 (8, 1). Then, using the intersection 5 (8, 1) as the starting point of the next basic figure, the drawing of the basic figure is repeated in the same manner, and when drawing to the intersection 6 (8, 1) which is the final point, the upper part of the original drawing can be drawn. Next, the lower side is drawn in the direction opposite to the upper side. In order to balance the figure, in the upper coordinate display, the right second intersection 7 (2, 1) of the intersection 4 (0, 1) is defined as the starting point (0, 1) of the basic figure drawn below. Then, if the intersections to be selected for drawing the first basic figure on the lower side are sequentially enumerated, the intersection 7 (0, 1), the intersection (2, 3a), the intersection (2, 3b), the intersection (4, 3b), This is intersection 8 (4, 1). Then, using the intersection 8 (4, 1) as the starting point of the next basic figure, the drawing of the basic figure is repeated in the same manner, and when drawing up to the intersection 9 (4, 1), the lower part of the original drawing can be drawn. Then, the intersection 4 and the intersection 7 that are the upper and lower starting points are connected, and the intersection 6 and the intersection 9 that are the final points are connected to each other, whereby a closed figure that is the original form of the second embodiment can be drawn.

  In Example 2, the original shape drawn in this way was transferred to a polypropylene sheet having a thickness of 0.5 mm and cut out with a knife or the like. This Example 2 is convenient when drawing a seam allowance with a width of 5.0 mm on a fabric based on a small pattern such as applique or quilting. Marks can also be marked at regular intervals.

  In the third embodiment, the imprinted figure is drawn with a larger mark than the other embodiments based on the sewing line having a large mold. Since the figure which shows the shape of Example 3 was shown in FIG. 4 which is a figure for demonstrating how to draw the original form, it abbreviate | omitted. In Example 3, as shown in FIG. 4, a base circle 1 having a radius of 250.0 mm and a circle concentric with the base circle 1 are used as floor circles, a floor circle 2a having a radius of 255.0 mm, and a floor circle having a radius of 260.0 mm. 2b, a group of floor circles increasing from the floor circle 2c having a radius of 270.0 mm to the floor circle 2f having a radius of 300.0 mm at intervals of 10.0 mm, a floor circle 3a having a radius of 245.0 mm, and a floor circle having a radius of 240.0 mm Floor circle 3b, floor circle 3c with a radius of 230.0mm, floor circle 3d with a radius of 220.0mm, floor circle group of floor circle 3e with a radius of 200.0mm, and a center line having a central angle of 0.625 degrees Each intersection with the group was obtained, and based on the original drawing in which basic figures drawn by connecting line segments connecting the selected intersections were connected and chained.

  In order to make the explanation of FIG. 4 easy to understand, the intersection point to be selected will be expressed by the coordinates of the center line and the circle. A certain intersection on the basic circle 1 is selected as the starting point for drawing the first basic figure, the coordinates are represented as (0, 1), and the center line passing through the first intersection to the right from the starting point and the floor circle 2a The coordinates of the intersection point with the center line are represented by (1, 2a), and the coordinates of the intersection point of the center line passing through the second intersection point from the start point to the left and the floor circle 3c are represented by (-2, 3c). The procedure for drawing the original drawing of Example 3 according to this notation will be described. First, draw the upper side of the original drawing. When the intersections to be selected for drawing the upper basic figure are sequentially listed, the start point (0, 1), the intersection point (2, 2b), the intersection point (−1, 2b), the intersection point (−1, 2c), the intersection point (2, 2c), intersection (2, 2d), intersection (-1, 2d), intersection (-1, 2e), intersection (2, 2e), intersection (-1, 2f), intersection (9, 2f), intersection ( 6, 2e), intersection (9, 2e), intersection (9, 2d), intersection (6, 2d), intersection (6, 2c), intersection (9, 2c), intersection (9, 2b), intersection (6 , 2b), intersection point (8, 1), intersection point (9, 2a), intersection point (11, 2a), intersection point 5 (12, 1). When the intersection 5 (12, 1) is the starting point of the next basic figure and the basic figure is similarly drawn seven times, the upper part of the original drawing can be drawn. Next, the lower side is drawn in the direction opposite to the upper side. In order to balance the figure, the upper coordinate display defines the intersection (-2, 1) as the starting point of the basic figure to be drawn below, and sequentially lists the intersections necessary to draw the lower basic figure. , Start point (0, 1), intersection point (3, 3b), intersection point (1, 3b), intersection point (1, 3c), intersection point (4, 3c), intersection point (4, 3d), intersection point (1, 3d), Intersection (1, 3e), intersection (11, 3e), intersection (11, 3d), intersection (8, 3d), intersection (8, 3c), intersection (11, 3c), intersection (11, 3b), intersection (9, 3b), intersection 8 (12, 1). Then, when the intersection 8 (12, 1) is the starting point of the next basic figure and the basic figure is similarly drawn seven times, the lower part of the original figure can be drawn. Then, the intersection (4, 2f) on the upper side of the left and right ends and the intersection (6, 3e) on the lower side are connected to each other, and both ends are cut to form a closed figure obtained by deforming the basic figures at both ends. The shape of In FIG. 4, a black-painted portion 10 is a portion that has been cut out so as to be more flexible and easier to handle, and is not related to the creation of the original shape of the third embodiment.

  In Example 3, the original shape drawn in this way was transferred to a polypropylene sheet having a thickness of 0.3 mm, cut out with a knife or the like, and the cut portion 10 was further cut out to produce Example 3. In the third embodiment, a sewing allowance can be easily drawn with a width of 10.0 mm based on a sewing line having a large mold by sewing or the like, and the size is enlarged or reduced with a width of 10.0 mm. It is also easy to draw a sewing line. Furthermore, using Example 3, it is also possible to mark a folding margin such as a skirt or trouser hem, or to draw a cutting line including a folding margin. Also, if you put a mark on the folding margin part and the stitching part, align the mark and hit the needle, it will be easier to sew the folding margin part to the sewing part. By tucking the looseness of the folding margin that occurs when the needle is put on after aligning the marks, it is possible to sew with a fine finish.

  Although the present invention has been specifically described with reference to examples and use examples, the shape, material to be manufactured, thickness, size, and the like are not limited thereto. Further, the application of the present invention is not limited to this.
