Abstract

PURPOSE:To satisfactorily know the approach and withdrawal of a person with one light-receiving means by arranging plural light-emitting means different in irradiation angle, receiving successively the light reflected from the person, and detecting the movement of the person. CONSTITUTION:At one side part of an inlet and an outlet, three infrared rays LED5a-5c are arranged at a desired position and respective irradiation directions C1-C3 are of angles theta1-theta3 (theta1>theta2>theta3) different from the surface of the inlet and outlet. A microcomputer 3 is synchronized to a switching control signal (a), three types of code signals b1-b3 are successively repeatedly generated, and supplied to a successive lighting-up circuit 4. Thus, the LEDs 5a-5c are light-emitted corresponding to the signals b1-b3. When an infrared ray light-receiving part 6 provided at the other side part of the inlet and outlet light-receives the reflecting light from the person, the part sends the light- receiving signal to an AND gate circuit 7. Since the signals b1-b3 are inputted to the circuit 7, the AND output is sent to the microcomputer 3. Consequently, when the microcomputer 3 knows the approach when the light-receiving signal is in the sequence of the C1-C3, knows the withdrawal when it is in the reverse sequence, and the voice response corresponding to respective is executed.
