<p>A rotary laser system comprising a body (1), and a plurality of object reflectors including a first object reflector (2) and a second object reflector (3). The body (1) includes a rotating unit for emitting light to the object reflectors; a detector for detecting the reflection from the object reflectors, the reflection being incident upon the body through the rotating unit; and a detecting circuit for discriminating the object reflectors depending on the output of the detector, so that the location and range to be scanned with a laser beam may be determined on the basis of the detection result. The reflection surface of each object reflector is divided into at least two. The marking operation can be accurately carried out by reciprocal scanning to confirm the position to be irradiated on the first object reflector while confirming the scanned position on the second object reflector. The dislocation, if any, of the rotary laser system after installed can be easily detected and corrected to ensure the accuracy in the marking operation. <IMAGE></p> |
