PROBLEM TO BE SOLVED: To provide an abnormality detection device for a passenger conveyor, which is capable of improving an attaching operation to the passenger conveyor.SOLUTION: This abnormality detection device for a passenger conveyor is provided with: a reflection plate that is provided to the side surface of a comb plate of the passenger conveyor; a photoelectronic sensor that projects light to the reflection plate and receives reflected light from the reflection plate; and an abnormality detection unit that acquires light reception information indicating the light reception state of the photoelectronic sensor. The abnormality detection unit is configured to detect that the passenger conveyor is abnormal when it is determined that the photoelectronic sensor does not receive the reflected light from the reflection plate from the received light information obtained from the photoelectric sensor.SELECTED DRAWING: Figure 3
【課題】乗客コンベアへの取り付け作業の改善を図った乗客コンベアの異常検出装置を得る。【解決手段】乗客コンベアの異常検出装置は、乗客コンベアのコムプレートの側面に設けられた反射板と、反射板に光を投光して反射板から反射光を受光する光電センサと、光電センサの受光状況を示す受光情報を光電センサから取得する異常検出部とを備え、異常検出部は、光電センサから取得した受光情報から、光電センサが反射板からの反射光を受光していないと判断した場合、乗客コンベアが異常であることを検出するように構成されている。【選択図】図3
