ABSTRACT:
An apparatus for detecting information indicative of the rotation of an engine is disclosed in which a multiplicity of magnetic poles are formed on a track along the circumferential periphery of a rotating member driven by an engine, thus detecting a rotational reference position and a rotational angle from the rotational reference position of the engine. A rotational reference sensor and an angle sensor for generating a signal representing a change in magnetic fluxes by detection of the magnetic fluxes from the track are arranged in opposition to the track in spaced relation from each other along the axis of the rotating member. Some of the magnetic poles on the track which are opposed to the rotational reference sensor are omitted, so that a signal representing the rotational reference position is generated in the case where the angle sensor detects magnetic fluxes but the rotational reference sensor fails to detect the same.
