されている。In these figures, (1) is a hollow rectangular tube made of metal or synthetic resin, and a fixed reflecting mirror (2) having a height approximately half the vertical width of the hollow rectangular tube (1) is provided in the middle thereof. It is inclined. The angle formed by the reflecting surface of the fixed reflecting mirror (2) and the central axis of the hollow prismatic tube (1) is smaller than 45 degrees. A movable reflecting mirror (3) is rotatably attached to the side of the opening formed in the side portion of the hollow rectangular tube (1), and the rotation fulcrum of the movable reflecting mirror (3) is
It is set on the front extension of the fixed reflecting mirror (2) in the longitudinal direction.

転するため、実際の角度の1/2のスケールで目盛られて
いる。分度目盛（５）の０の位置は、可動反射鏡（３）
と固定反射鏡（２）とのなす角度が90度になる位置であ
る。Since the image projected on the reflecting surface of the movable reflecting mirror (3) is rotated by 2θ when the movable reflecting mirror (3) is rotated by θ, the degree scale (5) is on a scale of 1/2 of the actual angle. It is graduated. The position of 0 on the degree scale (5) is the movable reflecting mirror (3).
It is a position where the angle between the fixed reflecting mirror (2) and the fixed reflecting mirror (2) becomes 90 degrees.
なお、固定反射鏡（２）の反射面と中空角形筒（１）の
中心軸線とのなす角度を45度よりも小さくしているの
