特徴とするビーム光走査装置。 A beam light scanning means 3 scans the beam S emitted from the light source 1 over a predetermined range in the vertical direction, and the beam light scanned by the beam light scanning means 3 is scanned around the vertical axis Y by a step motor. A plurality of beam light scanning devices A each equipped with a rotary scanning means M for scanning are each rotatably supported around the vertical axis Y, and a plurality of light reflecting means CC installed at a known fixed point are connected to each other. A beam light scanning device is provided with a means for detecting positional information of a beam light S emission point based on a detection result of a reflected light reception direction of To set the initial position of the moving angle θ, a light receiving means P that receives the beam light S emitted from the beam light scanning device A is placed at a position where the direction with respect to at least one of the beam light scanning devices A is constant. The rotation angle θ around the vertical axis Y at the time when this light receiving means P receives the beam light S is set as a reference angle θ 00 , and then each beam light scanning device A
Each rotation of the plurality of beam light scanning devices A is determined based on the detection result of the relative rotation angle θna with respect to the one beam light scanning device A at the time when the beam light scanning device A receives reflected light from a specific one of the light reflecting means CC. A beam light scanning device characterized in that it is provided with means for setting an initial position of an angle θ.
