Abstract
PURPOSE: To make it possible to move a body to be detected while discriminating its direction, by facilitating installation construction and also by simplifying the structure of a projection-photodetection part by constituting a projection part and photodetection part in one body.
CONSTITUTION: Light emitting elements 21 and 22 of projection part 7 provide light modulation with the output of modulating oscillator OSC1. To discriminate objective light from other natural light, driving circuit 10 is controlled by the output of oscillator OSC2 to supply the output of OSC1 to elements 21 and 22 by turns. At photodetection part 8, photodetector 4 detects reflected light of projected light from detected body 5 and its output is supplied to signal processing circuit 9 after amplification 11. Circuit 9, supplied with the output of OSC2 as well, discriminates between projected light from element 21 and that from 22 at its timing and then detects changes of photodetection signals to decide the existence of detected body 5. Further, its moving direction is decided by discriminating the order of the photodetection signals.
