An optical automatic counting machine that can count the number of piston rings used in a car engine is developed. Both edges on a piston ring are illuminate with two LEDs from the direction of±60° which is measured from the z-axis normal to the surface of the piston ring. The light scattered by the edges is detected perpendicularly upward. In this research, the technology to maintain the integrated value of the radiant fluxes of the light scattered by both edges, by controlling independently the radiant flux of the light generated by each LED, is developed. With this technology, a discontinuous point does not appear in the detected output signal, even if each LED is turned on or off. As a result, a continuous output signal can be detected when the bobbin with piston rings is driven horizontally. The number of piston rings is counted by counting the cross points between the output signal and the threshold signal, by adding the threshold signal to the detected output signal.
