Position determining apparatus and rotary laser apparatus used with the same |
摘要 |
The present invention provides a position determining apparatus that has a simplified configuration adapted to produce a horizontal reference plane and an inclined reference plane simultaneously. A position determining apparatus (100) according to the present invention comprises a rotary laser apparatus (151) that emits at least two fan-shaped laser beams diverting in a plane other than horizontal plane while rotating the laser beams about a given optical axis, and an optical sensor (154) that has at least one light receiving section receiving the fan-shaped laser beams. One of the fan-shaped laser beams is different in inclination angle from the other, and in terms of a state of the laser beams received at the light receiving section, a relative position of the optical sensor to the rotary laser apparatus can be determined.
