Abstract

PURPOSE: To enable circular arc running and straight line running with one photo detector, by assembling a photo element for circular arc running control and another photo element for straight line running with a photo detector.
CONSTITUTION: In a photo detector 1, when incident light is received from an opening 2a, the first photo detection signal incident through a half mirror 30 is received at a photo detection element for circular arc running, and the second photo detection signal reflected on the mirror 30 is received at a photo detection element for straight line running. In circular arc running control, a projector 10 is placed on the center of a circular arc and it is rotated along the working plane, and the photo detector 1 is located orthogonally to the progressing direction of a car. In case of straight line running control, the projector 10 is placed in front of the car and fixed toward the car and the photo detector 1 is located toward the car progressing direction. Thus, one set of photo detector can serve to circular arc and straight line running.
