Abstract
The system according to the present invention comprises means for irradiating a plurality of laser beams by separating the laser beams in a vertical direction and means for forming a plurality of laser beam reference planes by rotary irradiation of said plurality of laser beams. Because a plurality of reference planes are formed at the same time, operation can be carried out at the same time at different working sites, and the tilt reference line as desired can be promptly obtained without performing tilt setting operation for the reference plane.
Claims13
A rotary laser irradiating system for emitting a plurality of laser beams by rotary irradiation and for forming a plurality of laser reference planes, comprising a laser light emitting unit for emitting said plurality of laser beams, the light emission of which is capable of being respectively controlled, and a rotator for projecting said plurality of laser beams by rotary irradiation in predetermined angles upward and downward and for forming a plurality of laser reference planes including a plane, wherein said rotary laser irradiating system forms said plurality of laser reference planes capable of being identified by controlling said light emission.
A rotary laser irradiating system for emitting a plurality of laser beams by rotary irradiation and for forming a plurality of laser reference planes, comprising a laser light emitting unit for emitting said plurality of laser beams, a rotator for projecting said plurality of laser beams by rotary irradiation in predetermined angles upward and downward and for forming said plurality of laser reference planes including a plane and, a diffraction member provided on said rotator and for forming dividing patterns in rotating directions in such a manner that the aspect is different for each of said plurality of laser beams, wherein said plurality of laser reference planes are formed so as to be capable of being identified.
