沿って移動する状況。FIG. 1 shows a surface displaying roads whose center points and intersections are difficult to read with conventional cursors. α, β: Road, A, B, points at both ends of the road, M: Center point of the road, dotted line...center line of binary path, P: α of the road. Intersection of the center lines of β. FIG. 2 shows a coordinate reading cursor according to the present invention. Second
Figure 1 is an elevational view, Figure 2 is a front view, Figure 2 is a front view, and Figure 2 is a side view. 1: Reading part of the cursor, 2: Measuring part of the cursor, 3
: Scale that displays vertical and horizontal directions, 4: Scale that displays angle, 5: Scale that displays equicentric distance. FIG. 3 shows a situation in which an unspecified point B at a fixed position is read with respect to a point A specified by a symbol using the Carlso of the present invention. Figure 4 shows how the cursor of the present invention divides two clearly marked points A and B on a straight line at a constant ratio.
This figure shows the situation in which point P is read. Arrow points the cursor to straight A
Indicates that it is to be moved along B. FIG. 5 shows a situation in which the center point of a road or the intersection of the center lines of two roads is found using the cursor of the present invention. α, β: Road, A, B: Points at both ends of the road, M: Center point of the road, P: Intersection of each center line of two roads α, β, Dotted line: Center line of arch road, Arrow: Cursor A situation where you move along the center of the road.

Claims

[Scope of utility model registration request]

A scale that indicates the position in the vertical and horizontal directions from the center 0 of the transparent plate or lens plate by a plurality of mutually orthogonal parallel lines on the entire surface of the transparent plate or lens plate that is in contact with the surface on which the coordinate points are indicated with symbols. A cursor for reading coordinates, characterized in that it is provided with a scale for displaying the angle of radiation from the center O, and a scale for displaying the equicentric distance from the center O by concentric circles.
