Abstract
A method of detecting a reference angular position of a rotary body. Two detectable portions are spaced apart from each about the periphery by a predetermined angle in the rotational direction thereof. Two detection signals and produced from two detectors spaced apart from each other by the same angular distance as the detectable portions in the rotational direction of the rotary body in the vicinity of the locus of the detectable portions. It is first detected that at least one of the detectors produces a detection signal and thereafter it is determined that the rotary body takes a reference angular position when both of the detectors produce the detection signals.
