Abstract
PURPOSE: To provide an apparatus for detecting direction of movement of a moving body, in which quantity of light received by a light receiving element within a given time is changed with direction of movement of a moving body, whereby it is enabled to detect the direction of movement by means of a set of photo-sensors.
CONSTITUTION: A set of photo-sensor is constituted by a light source 11 and a light receiving element 12 and they are placed such that they face each other and body 14 passes between them. A screen plate 21 is further placed in the manner that its surface faces the light receiving surface of the light receiving element 12, and a plurality of thru-holes 22, 23 having different areas are formed in the portion of screen plate 21 facing the light receiving element 12, along the direction of movement of moving body. Output of the element 12 is afforded to variation detecting circuit 24 which detects change of output signal from the element 12 caused with movement of moving body 14 and variation of quantity of light received by the element 12 a certain time after starting of the variation, whereby it gives a judgement signal indicating the direction of movement of body 14.
