The first problem to be solved is to provide a template ruler on which a mandala pattern or the like can be drawn.

The second problem to be solved is that the pen tip does not hit the part of the window frame in which the shape of the template ruler is drilled, which is larger than 180 degrees and smaller than 360 degrees. It is to stick out.

The third problem to be solved is that when one line of a predetermined figure to be drawn is drawn inside another line closed in a ring shape, such as a double circle, it is fixed along the guide. If the template ruler has a window hole corresponding to the one line and a window hole corresponding to the other line, the alignment becomes difficult.

The present invention is a set consisting of a template ruler for drawing a predetermined figure and a guide used together with the template ruler, and the template ruler is fixed at every three equal or more equal division angles of 360 degrees along the guide. By rotating the template ruler, the center of rotation is constant and the template ruler is rotated only at the same equal angle, and each rotation angle is along the portion of the window frame in the window hole of the template ruler. The first feature is that the predetermined figure is drawn in one rotation by drawing the same figure for each.

The present invention is based on 180 degrees in the window frame of the window holes that are assumed to be opened when drawn with one template ruler without using the set consisting of the template ruler and the guide used together with the template ruler. The portion of the window frame that forms a corner portion that is larger than 360 degrees is an angle that is greater than 0 degrees and less than 180 degrees in the window frame of the window holes for each rotation angle in the set consisting of the template ruler and the guide used with it. The second feature is that it is composed of a portion of the window frame having a drawing instruction line indicated only at the position to be drawn forming the portion.

The present invention relates to the template ruler for drawing the one line and the other line when one line of the predetermined figure is drawn inside another line closed in a ring shape. The third feature is that the window holes are shared by the window holes for each rotation angle.

Since the set consisting of the template ruler of the present invention and the guide used together with the template ruler has the first feature, there is an advantage that it is possible to provide a template ruler capable of drawing a mandala pattern or the like.

Since the set consisting of the template ruler of the present invention and the guide used with the template ruler has the second feature, the angle of the window frame in which the shape of the template ruler is perforated is larger than 180 degrees and smaller than 360 degrees. Since the pen tip does not hit the part that constitutes the window, there is an advantage that the problem of protruding is solved.

Since the set consisting of the template ruler of the present invention and the guide used with the ruler has the third feature, one line of a predetermined figure to be drawn, such as a double circle, is a line of another line closed in a ring shape. There is an advantage that the figure drawn on the inside can be easily drawn without the difficulty of alignment.

FIG. 1, FIG. 2 or FIG. 3 of the embodiment of the present invention is a set including a template ruler 101 for drawing the figure shown in FIG. 9 and a guide 102 used together with the template ruler 101, and is a 360-degree 8 along the guide 102. By rotating the template ruler 101 by fixing it at equal division angles, the template ruler 101 rotates only at an angle of 8 equal divisions with a constant rotation center, and is among the window holes of the template ruler 101. By drawing the same figure for each rotation angle along the portion of the window frame having the drawing instruction line shown on the window frame, the figure shown in FIG. 9 is drawn in one rotation. The shape of the guide 102 shows an example, and it goes without saying that various examples such as a gear shape and a wavy shape can be considered.

FIG. 4 or FIG. 5 of an embodiment of the present invention is a set consisting of a template ruler for drawing the figure shown in FIG. 9 and a guide used together with the template ruler, and is a case where the ruler is rotated only at an angle of 360 degrees divided into eight equal parts. This is an example of the window hole portion of the template ruler.
If the drawing line 103A of FIG. 9 is drawn with one template ruler without using the set consisting of the template ruler of this embodiment and the guide used together with the drawing line 103A, the window hole expected to be opened is formed. Although not shown, it is the same as the window hole 104A. Of the assumed window holes, the pen tip does not hit the portion of the window frame that forms a corner portion larger than 180 degrees and smaller than 360 degrees, so that the pen tip protrudes.
The drawing line 103A of FIG. 9 is drawn only at the position to be drawn, which is a corner portion of the window frame of the window hole 104A that is larger than 0 degrees and smaller than 180 degrees, as shown in FIG. 4 or 5 of the embodiment. The portion of the window frame having the indicator line 105 and the window frame having the drawing indicator line 105 shown only at the position to be drawn forming the corner portion of the window frame of the window hole 104B that is larger than 0 degrees and smaller than 180 degrees. By drawing along the part at the rotation angle of 0 degrees and the rotation angle of 45 degrees, the part of the window frame to be drawn has a part that constitutes an angle larger than 180 degrees and smaller than 360 degrees. Since it is prevented from occurring, the predetermined figure is drawn and the window is drawn without following the portion of the window frame that forms a corner portion larger than 180 degrees and smaller than 360 degrees in the window frame among the assumed window holes. The problem that the pen tip does not hit the window frame at the corner of the window frame that is larger than 180 degrees and smaller than 360 degrees and sticks out is solved.
FIG. 4 is an example of a window hole portion when drawing the window frame among all the window holes according to a drawing rule of drawing along the portion of the window frame indicated by the drawing instruction line.
In FIG. 5, in the case of a window hole having a drawing instruction line, drawing is performed along the portion of the window frame indicated by the drawing instruction line, and in the case of a window hole having no drawing instruction line, drawing is performed along the entire window frame. This is an example of the window hole portion when drawing according to the drawing rule.
In the case of the example of FIG. 5, it is necessary to determine whether or not the window hole has a drawing instruction line, whereas in the case of the example of FIG. 4, the window frame of all the window holes is drawn. Since it is sufficient to draw along the part of the window frame indicated by the instruction line, the user does not get lost.

Since the drawing line 103B of FIG. 9 is drawn inside the drawing line 103C closed in an annular shape, the template ruler of the present invention is not used, and the window hole 104C and the window hole 104D are added to the template ruler that is not fixed along the guide. If the window holes have the same shape, alignment becomes difficult.
When the rotation angle is 0 degrees along the window frame in the window hole 104C and the window frame in the window hole 104D by using the set consisting of the template ruler 101 of this embodiment and the guide 102 used together with the ruler 101. By drawing at the rotation angle of 270 degrees, the difficulty of alignment is eliminated and the drawing can be easily performed.
