To improve detection accuracy of opening/closing of an elevator door.SOLUTION: In a door opening/closing detection system including a magnetic sensor installed in a car of an elevator and an opening/closing detection device for detecting the opening/closing of a landing door made of metal based on whether or not a difference in measured values between time intervals of the magnetic sensor exceeds a threshold, a magnet is provided in the landing door or in the vicinity of the landing door.SELECTED DRAWING: Figure 1

    【課題】エレベーターのドア開閉の検出精度を向上させる。【解決手段】エレベーターのかごに設置された磁気センサーと、磁気センサーの時区間における計測値の差分が閾値を超えたか否かに基づいて金属製の乗場ドアの開閉を検出する開閉検出装置とを備えたドア開閉検出システムにおいて、乗場ドアまたは乗場ドアの近傍に磁石が備えられる。【選択図】図1
