うにどの部分も均一に伸縮する素材に等分目盛り
を付けた等分尺を用い、その一方の端を固定しも
う一方の端を任意の長さに応じ自在に移動できる
ようにし両端を直線に合わせ、等分尺の目盛りを
直線に打つだけで、求める直線の等分割点が得ら
れる仕組みを有する直線等分割器。 A part of the main body becomes a ruler, using a material like rubber or a spring that expands and contracts uniformly, and using an equal scale with equal division scales, one end is fixed and the other end is A straight line divider that can be moved freely according to the length, and has a mechanism that allows you to obtain the desired equal division points of the straight line by simply aligning both ends with a straight line and marking the same scale on the straight line.
