Abstract: PROBLEM TO BE SOLVED: To obtain a linear scale by which the origin position can be obtained with high accuracy by using a simple configuration by a method wherein three center-of-gravity positions which give the origin position are set in advance and the origin position is found on the basis of the relationship between the positions and a computed center-of-gravity position.

The clock is set on the horizontal axis together with the center of gravity A, the center of gravity is set on the vertical axis, and the position (a) of the clock corresponding to the center of gravity A is found by a linear approximation on the basis of positions of the center of gravity before and after the value of the center of gravity A. The position (a) is used as the origin on the clock, and the position of the center of gravity A is used as the origin.
