PROBLEM TO BE SOLVED: To provide a foreign matter detection device which can accurately detect a foreign matter such as a string caught in a door.SOLUTION: A foreign matter detection device comprises: a landing door 11-1; a detector 18; a drive device 19; a control device 20; and a detection device 21. The detector 18 can be arranged on a protrusion position where the detector protrudes to a side part of the landing door 11-1, from a plane including an end surface 11-1a of the landing door 11-1, and a non-protrusion position where the detector does not protrude. The control device 20 controls the drive device 19 when the landing door 11-1 is closed, and moves the detector 18 along the end surface 11-1a, in a state in which the detector 18 is arranged on the protrusion position. The detection device 21 detects existence of the foreign matter caught in the landing door 11-1, by movement of the detector 18.SELECTED DRAWING: Figure 3

    【課題】ドアに挟まれた紐等の異物を精度良く検出することができる異物検出装置を提供する。【解決手段】異物検出装置は、乗場ドア11−1、検出子18、駆動装置19、制御装置20及び検出器21を備える。検出子18は、乗場ドア11−1の端面11−1aを含む平面から乗場ドア11−1の側方に向けて突出する突出位置及び突出しない非突出位置に配置可能である。制御装置20は、乗場ドア11−1が閉じられると駆動装置19を制御し、検出子18を突出位置に配置させた状態で検出子18を端面11−1aに沿って移動させる。検出器21は、検出子18が移動することによって乗場ドア11−1に挟まれた異物の存在を検出する。【選択図】図3
