PROBLEM TO BE SOLVED: To provide a chain elongation detection device and a passenger conveyor with the elongation detection device capable of achieving reduction of work time for chain elongation inspection and securing re-productivity and accuracy of the chain elongation inspection.SOLUTION: By subjecting an image to image analysis, where the image obtained by photographing an engaging state between a chain and a sprocket from a side direction of the sprocket during driving a chain transmission device, change of a position of a chain pin in teeth of the sprocket is calculated to detect elongation of the chain on the basis of calculated result.SELECTED DRAWING: Figure 9

    【課題】チェーンの伸び検査の作業時間の短縮を実現するとともに、チェーンの伸び検査の再現性および精度を確保することのできるチェーン伸び検出装置およびそのチェーン伸び検出装置を備えた乗客コンベアを得る。【解決手段】チェーン伝動装置が駆動する間におけるチェーンとスプロケットとの噛み合い状態を、スプロケットの側面方向から撮影した画像を画像解析することで、スプロケットの歯内でのチェーンのピンの位置の変化を算出し、算出結果に基づいてチェーンの伸びを検出するように構成する。【選択図】図9
