OPTICAL AXIS ADJUSTING JIG, MULTIPLE OPTICAL AXIS PHOTOELECTRIC SENSOR AND OPTICAL AXIS ADJUSTING METHOD OF THIS SENSOR

摘要

PROBLEM TO BE SOLVED: To facilitate the adjusting of an optical axis, in a multiple optical axis photoelectric sensor. ;SOLUTION: An optical axis adjusting projecting part 15 and a target mark 18 are provided in both sides of a projector 11 of a multiaxis electric photosensor. A target mark 16 for receiving light from the adjusting projecting part 15 and an adjusting projecting part 17 for incidence of light to the projector 11 are provided in a light receiver 12. An optical axis of the adjusting projecting parts 15, 17 is provided so as to be in parallel to an optical axis of the projector 11 and the light receiver 12. thus by adjusting light of the adjusting projecting part so as to be incident in a prescribed position of the target mark, the optical axis of the projector 11 and the light receiver 12 can be adjusted.;COPYRIGHT: (C)1997,JPO
