To provide a chain elongation detection device of a passenger conveyor that can accurately detect an elongation of a chain remotely.SOLUTION: A chain elongation detection device of a passenger conveyor according to an embodiment comprises: a first sensor unit 11 that detects a rotation state of one sprocket of a pair of sprockets having a chain hung thereacross and outputs a first rotation-detected signal; a second sensor unit 12 that detects a rotation state of the other sprocket and outputs a second rotation-detected signal; and a control part 13 that detects an elongation of the chain on the basis of a difference between a phase of the first rotation-detected signal and a phase of the second rotation-detected signal.SELECTED DRAWING: Figure 3

    【課題】チェーンの伸びを遠隔においても正確に検出することができる乗客コンベアのチェーン伸び検出装置を提供する。【解決手段】実施形態の乗客コンベアのチェーン伸び検出装置は、チェーンが掛け渡された一対のスプロケットのうち、一方のスプロケットの回転状態を検出して第1回転検出信号を出力する第1センサユニット11と、他方のスプロケットの回転状態を検出して第2回転検出信号を出力する第2センサユニット12と、第1回転検出信号の位相と、第2回転検出信号の位相と、の差に基づいてチェーンの伸びを検出する制御部13と、を備える。【選択図】図3
