To provide a positioning device capable of positioning control with high accuracy.SOLUTION: A positioning device includes an actuator consisting of a DC motor, a reduction mechanism, and a single-phase rotation sensor that detects the amount of rotational displacement of the reduction mechanism, and an electronic control device 1 for electrically driving the DC motor. The electronic control device 1 defines a target rotation stop position MP as a location roughly midway between a rising edge N+4f and a falling edge N+4r of an output pulse of the rotation sensor and performs a deceleration control to stop the DC motor.SELECTED DRAWING: Figure 5 【課題】高精度の位置決め制御を可能とする位置決め装置を提供する。【解決手段】位置決め装置は、直流モータと減速機構及び減速機構の回転変位量を検出する単相式の回転センサーとによって構成されたアクチュエータと、直流モータを電気的に駆動する電子制御装置１とから成る。電子制御装置１は、回転センサーの出力パルスの立ち上がりエッジＮ＋４ｆと立下りエッジＮ＋４ｒとの略中間位置を目標回転停止位置ＭＰとして、直流モータを停止させるように減速制御する。【選択図】図５
