Abstract
PURPOSE: To provide an optical angle detector for detecting the crank angle of an engine by readily mounting the detector in narrow space for measuring ignition timing and lead angle without altering any of equipment carried on a vehicle.
CONSTITUTION: A photo coupler 3 is set at predetermined position by controlling flexible links 4a, 4b. The light from a light emission diode 3a is detected by a phototransistor 3b via a reflector 2 on the surface of a crank pulley 1 rotating thereat. The compared voltage is regulated by a variable resistor 5a in response to the reflected light amount to obtain a light passage detection signal of the reflector 2 by the output from a voltage comparator 5b to thus detect the crank angle with the signal as a standard.
