Abstract
PURPOSE: To clearly indicate a marking line on the ceiling, the floor, the wall surface, etc., by providing a level on the standard base mounted onto the tripod, and providing a laser apparatus for generating a laser beam (line), around the horizontal rotary shaft installed to the bearing part on the standard base, so that it can rotate freely.
CONSTITUTION: The standard base 3 equipped with a level 1 is installed to the upper surface of the tripod 2, and a horizontal rotary shaft 7 is provided through the bearing 6 of the bearing supporting part 4 fixed to said base. A laser apparatus 8 is installed to the tip 11 of the rotary shaft 7, and emits a laser beam (laser line) 9. When the level 1 is adjusted to a horizontal plane, the rotary shaft 7 becomes horizontal, as well, and when the laser apparatus is rotated around the rotary shaft 7, the laser beam 9 scans on the ceiling, the floor and the wall surface, and 4 irradiation lines for marking are indicated clearly.
