Abstract
A rotary laser emitting apparatus that rotates and emits a laser beam comprises an emission-side control unit that controls an entire operation of the apparatus, a laser emitting mechanism that emits the laser beam while rotating an irradiation optical axis that is an emission direction of the laser beam, and a rotating direction detecting unit that detects a rotating direction of the irradiation optical axis. The emission-side control unit generates a rotating posture signal showing the rotating direction of the irradiation optical axis detected by the rotating direction detecting unit and drives the laser emitting mechanism for superimposing the rotating posture signal on the laser beam.
