動方向の検出装置。[Claims for Utility Model Registration] Reflective surfaces of a certain width in the direction of movement are arranged in advance on the surface of a moving object, alternating with non-reflective surfaces,
A device that simultaneously detects the moving speed and moving direction of the moving object using reflected light from the reflecting surface, comprising: a light emitting element that irradiates light onto the reflecting surface of the moving object; and a light emitting element parallel to the moving direction of the moving object. a light-receiving element having two light-receiving elements or two light-receiving parts disposed in the area and receiving reflected light from the reflecting surface of the moving object; and exclusive logic of output signals of the two light-receiving elements or two light-receiving parts. A first exclusive OR circuit that calculates the sum, calculates the exclusive OR of the output signal of one of the two light receiving elements or the two light receiving sections, and a signal that is inverted by an inverter and delayed by a delay circuit. a second exclusive OR circuit; a counter for counting the pulse train of the output of the first exclusive OR circuit within a unit time given by a clock signal;
a D-flip-flop that outputs the state of the output signal of the first exclusive OR circuit at the time of pulse input of the output signal of the exclusive OR circuit; output signals of the two light receiving elements or the two light receiving sections; 1. A device for detecting the moving speed and direction of a moving object, characterized in that a circuit element for simultaneously detecting the moving speed and moving direction of a moving object is incorporated into one package to form an integrated structure.
