ーの保守作業の能率を向上する効果がある。Thus, when the teeth of the comb are damaged by foreign matter fitted in the grooves between the crosspieces of the tread, the damaged comb is removed and a detector is temporarily provided at that position. When the passenger conveyor is operated in this state, the detection plate corresponding to the groove in which the foreign matter is present is pushed and displaced by the foreign matter in the groove. For this reason, the presence of the foreign matter fitted in the groove can be easily and reliably recognized, and the fitted foreign matter can be accurately removed. Therefore, when the teeth of the comb are damaged due to the collision of the foreign matter, it is possible to solve the problem that the damage of the same foreign matter occurs again on the tooth of the new comb which is replaced by overlooking the fitted foreign matter. This has the effect of improving the efficiency of maintenance work on the passenger conveyor.

ヤーの保守作業の能率をさらに向上する効果がある。In this way, when the teeth of the comb are damaged by foreign matter fitted in the grooves between the crosspieces of the tread, the damaged comb is removed and a detector is temporarily provided at that position. When the passenger conveyor is operated in this state, the detection plate corresponding to the groove in which the foreign matter is present is pushed and displaced by the foreign matter in the groove. Then, the notification device operates by the displacement of the detection plate, and the presence of the foreign matter is automatically notified by the notification device. This makes it possible to more easily and surely recognize the presence of the foreign matter fitted in the groove, and to remove the foreign matter fitted properly. Therefore, when the teeth of the comb are damaged due to the collision of the foreign matter, it is possible to eliminate the problem that the fitted foreign matter is overlooked and the damaged tooth of the new comb is replaced by the same foreign matter. Therefore, there is an effect that the efficiency of the maintenance work of the passenger conveyor is further improved.
