Conventional technology and the points between them Conventional ellipse compasses are made by combining large and small disks to draw an ellipse according to the scales attached to the long and short diameter disks, or by using a link mechanism. It has been proposed to draw a part of an ellipse and then sequentially move the drawing position so that a complete ellipse is drawn. However, in both the disk type and link type (actual type), the major axis and minor axis of the ellipse drawn are set by a combination of the vertical and horizontal axes. Therefore, in the former case, due to its structure, the size of the ellipse that can be drawn is small compared to the size of the ellipse compass, and it takes a lot of work to make the disk a perfect circle.

In addition, in the latter case, the ellipses are drawn part by part and added sequentially, so
The wire connections are not accurate, and the operation is difficult.Either method requires precision in processing, and has the disadvantage of being complex and expensive.

In view of this, the present invention simplifies the structure by combining circular motion rather than marking the vertical and horizontal axes, and the ellipse t, which is relatively large compared to the size of the ellipse compass itself, can be drawn with simple operations. , and to be able to provide it at a low cost.

If the radius of the second gear 8 is R1 and the radius tr of the third gear 11, then when a point P on the circumference of radius r whose center is on the circumference of radius R is on the X axis, its coordinates are (±( R+r)・0). If 0.0' on the X-axis and the angle θ on the acute side of the X-axis, then point 0' on the circumference of radius R and point P on the circumference of radius r
If the straight line connecting these rotates in the opposite direction while maintaining the same angle to the X axis, the trajectory of this point P will become an ellipse. When this third gear 1 revolves around the main shaft 1, it is meshed with the first gear 4 on the main shaft via the second gear 8t, so when the third gear revolves, the second gear 8 rotates in the normal direction. , the third gear will rotate in the opposite direction.
