検出装置。 A sensor section consisting of an incremental encoder with a zero point having the same rotational axis as the rotating body, a rotating slit disk attached to the same rotating shaft, and a group of proximity switches for detecting the slit position of the rotating slit disk, and an incremental encoder.・The rotation angle of the rotating slit disk is calculated based on the phase determination circuit that determines the phase of the two-phase signal that is the output of the encoder and generates up/down signals to the counter, and the signals from the proximity switch group of the sensor section. A rotation angle decoding circuit, a system reset circuit that generates a counter set signal when the system is set, and a system reset circuit that reversibly counts the up/down signals of the phase determination circuit and resets the count value using the zero point signal of the incremental encoder. A rotation angle detection device for a rotating body, comprising: a rotation angle signal processing section comprising a counter having a function of setting an initial value of the counter which is an output of the rotation angle decoding circuit in response to a set signal from the reset circuit; .
