| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide means for detecting anomaly of a step shape, such as projection of fastening screw for a tread, lifting of the tread or breakage of a rear wheel even when a step tread is not in parallel with a step advancement direction.SOLUTION: A line sensor is disposed on a return side of a step to measure a substantially vertical directional position of a step tread and detects anomaly of a step shape by comparing with a normal value.SELECTED DRAWING: Figure 1
【課題】ステップ踏面がステップ進行方向と非平行な場合でも踏板の止めねじの突出、踏面の浮き上がり、あるいは、後輪の破損などのステップ形状の異常を検知する手段を提供する。【解決手段】ステップの返り側にラインセンサを配置してステップ踏面の略垂直方向位置を計測し、正常値と比較してステップ形状の異常を検出する。【選択図】 図１ |
