Abstract

PURPOSE: To make a display based on color, sound, etc., possible to facilitate the installation work by digitizing a light receiving quantity and dividing it to many stages.
CONSTITUTION: Light supply equipment 2 and light receiving equipment 3 are arranged oppositely, and optical signals modulated by 1 are supplied to detect a moving object on a basis of the presence or the absence of light shielding, and light receiving signals are converted to binary signals consisting of plural bits by A/D converter 7 after demodulation, and the magnitude of the light receiving quantity in optical axis aligned at an installation time is displayed on 9 is steps by combinations of upper two bits of binary signals. Then, reporting output signal a after installation is taken out.
