To provide a passenger conveyor inspection device that can inspect the fastening state of fixtures under various environments.SOLUTION: In a passenger conveyor comprising a circulating chain and a plurality of steps connectable to the chain, a passenger conveyor inspection device that can inspect the fastening state of fixtures colored in a predetermined color used for fixing each of the plurality of steps to the chain comprises a calculation unit that calculates a threshold value for detecting the fixtures based on an image of a calibration member captured by an imaging device for detecting the fixture provided in the vicinity of the fixture, and a determination unit for determining the fastening state of the fixture based on the threshold value calculated by the calculation unit for the image of the fixture captured by the imaging device.SELECTED DRAWING: Figure 1

    【課題】多様な環境下において固定具の締結状態を点検し得る乗客コンベア点検装置を提供する。【解決手段】循環移動するチェーンと、チェーンに連結可能な複数のステップとを備える乗客コンベアにおいて、複数のステップの各々をチェーンに固定するために用いられる所定の色に着色された固定具の締結状態を点検する乗客コンベア点検装置であって、固定具の近傍に設けられている固定具を検出するためのキャリブレーション部材が撮像装置により撮像されたキャリブレーション部材の画像をもとに、固定具を検出する閾値を算出する算出部と、固定具が撮像装置により撮像された固定具の画像について、固定具の締結状態を算出部により算出された閾値に基づいて判定する判定部と、を設けるようにした。【選択図】図1
