Claims

[Claims for Utility Model Registration] 1. Each true sphere of equal mass can be freely pressed into contact with both side surfaces of a weight fixed at the bottom of a pointer with a vertical indicating ruler consisting of parallel outer edges that vibrate freely. A three-dimensional angle measurement device consisting of a device attached as shown in the figure. 2. The solid angle measuring instrument according to claim 1, wherein the vertical indicating ruler is a cross-shaped ruler that intersects perpendicularly. 3. The solid angle measuring instrument according to claims 1 and 2 of the utility model registration claim, which is a hollow true spherical shell.
