摘要: A technique for more smoothly moving a reflective prism to a target position is provided. A surveying instrument 100 includes a leg part 101, a base 102 supported by the leg part 101, a movable part 112 held by the base 102 and being movable straight in any direction within a two-dimensional plane relative to the base 102, a reflective prism 113 mounted on the movable part 112, and a laser pointer 114 that is mounted to the movable part 112 and that emits a guiding light in a vertical direction.
