PROBLEM TO BE SOLVED: To provide a laser range finer capable of preventing malfunction from being occurred.SOLUTION: A laser range finder 1 includes: a housing 11; a light source 10 arranged in the housing 11, and emitting laser light; a scan mirror 20 scanning the laser light from the light source 10 in a mirror scan area; a reflection plate 52 arranged in the mirror scan area and the housing 11, and reflecting the laser light from the scan mirror 20; a light shading member 51 arranged in a range finding area out of the mirror scan area and in the housing 11, and limiting intensity of the laser light from the scan mirror 20 to transmit the laser light to the outside of the housing 11; a light reception unit 30 receiving reflected light from an object and the reflection plate 52 of the laser light scanned by the scan mirror 20; and a signal processing unit 60 calculating a direction of the object to the laser range finer 1 by using timing when the light reception unit 30 receives the reflected light.SELECTED DRAWING: Figure 1 |
