項記載の回転体の回転方向検出装置。[Claims for Utility Model Registration] (1) In a rotational direction detection device for electrically detecting the rotational direction of a rotating body, the rotating bodies are rotatably connected to each other along a frame of the rotating body. A plurality of coil detectors are arranged in parallel in the rotational direction of the rotating body and each detects the rotating magnetic field of the rotating body as a current, and a phase detection circuit detects and compares the phase of each current signal of the coil detector. Features: A device for detecting the rotational direction of a rotating body. (2) The phase detection circuit includes a pulse signal generation circuit that generates a plurality of pulse signals synchronized with each current signal from each current signal of the plurality of coil detectors; Claim No. 1 for Utility Model Registration, characterized in that it consists of a flip-flop that detects the phase difference of signals.
The rotational direction detection device for a rotating body as described in 2.
