Abstract
An optical axis tilting device of a laser optical system, includes a lens barrel inside of which provided with a laser optical system; a tilt frame supported at the lens barrel; a tilt sensor which is provided at the tilt frame and is configured to detect a preset reference position of the tilt frame; a fixed frame fixed to the lens barrel and provided with a tilting mechanism which tilts the tilt frame relative to a horizontal plane; a leveling mechanism which supports the lens barrel tiltably, and tilts the lens barrel so as to detect the reference position by the tilt sensor and then levels the tilt frame; a feed screw which is rotatably driven by a driving motor; a feed piece which is reciprocated by the feed screw and engages with the tilt frame and tilts the tilt frame relative to the reference position; a piece position detection device configured to detect a position of the feed piece; and a computing device configured to calculate a tilting angle based on the position of the feed piece detected by the piece position detection device.
