PURPOSE:To construct a mechanism part which adjusts the posture of a projector for range-finding at low cost and to efficiently execute adjusting operation. CONSTITUTION:A supporting shaft 16 is protrusively provided on a holding plate 15 and fitted in the recessed part 23 of an adjusting plate 22 where the projector 20 is stuck and fixed. A coil spring 18 is interposed between the holding plate 15 and the adjusting plate 22 so that the surface of the adjusting plate 22 is pressed to be inclined in one direction. Adjusting screws 26a and 26b are screwed in the screw holes 17a and 17b of the holding plate 15 through holes 24a and 24b. By adjusting the screwing amount of the screws 26a and 26, the direction of the surface of the adjusting plate 22 is changed and the direction of the optical axis of projected light is adjusted. |
