Deviation detection device, rotary laser apparatus with the same, and position determining system with deviation detecting/correcting device |
摘要 |
<p>The present invention is directed to a deviation detecting device that detects a deviation angle of a rotary unit of a laser light projector relative to a projector body. The deviation detecting device (190) includes a light emitter (193) attached to the projector body of the laser light projector for emitting laser light, a reflector (195) attached to the rotary unit of the laser light projector for reflecting light emitted from the light emitter, and a light receiving unit (194) attached to the projector body of the laser light projector for receiving the light reflected by the reflector. In the deviation detecting device, a position at which the light reflected by the reflector is incident upon the light receiving unit is utilized to determine a deviation angle of the rotary unit relative to the projector body. <IMAGE></p> |
