Document Type and Number:
Japanese Patent JP2018052650
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To remove the high possibility of damaging a comb plate and a footboard during control executed to stop a passenger conveyor due to the entry of a foreign object into a gap between the comb plate and the footboard.SOLUTION: A displacement detection unit is attached to a comb plate of a side opposed to a footboard, and detects the height-direction displacement of the footboard which horizontally moves. A control unit detects the occurrence of an abnormality in the footboard when a displacement amount calculated from reference displacement on the basis of the displacement of the footboard exceeds a threshold value used for detecting the abnormality of the footboard before the footboard comes into contact with comb teeth, and carries out a different operation for dealing with the abnormality of the footboard for each threshold value exceeded by the displacement amount from the reference displacement.SELECTED DRAWING: Figure 1
