出装置。 A pair of rotation sensors are arranged with different detection phases relative to the rotating body, and changes in the output of these pair of rotation sensors are used as interrupt inputs, and the output of the rotation sensor is detected when a certain period of time unique to the device has elapsed. The central processing unit that calculates the rotational position of the rotating body and the central processing unit that calculates the rotational position of the rotating body, and if the output of the rotation sensor disappears at the time when this central processing unit captures the output of the rotation sensor, it is assumed that there is no interrupt input. A rotational position detection device consisting of a working monitoring means.
