Abstract
PURPOSE: To detect accurately an edge formed by two planes of a black object or the like by arranging the position of a reflex type photoelectric-switch which uses the light-emitting diode of a red light as a light source so that only one of the detecting planes can be detected.
CONSTITUTION: To detect the edge line 13 formed by two planes 12a and 12b of a black object 12 crossing each other, a reflex type photoelectric-switch 9 is so arranged that it detects the surface 12a but not the section face 12b. In other words, previously the switch 9 is experimentally placed at the distance L' from where it can not detect the section face 12b, and the rubber object 12 is moved in the direction of the arrow 14. The point at which the switch 9 is turned off is the location of the edge line 13. Thus, the position of the edge 13 can be detected.
