Human detector for passenger conveyor

Provided is a human detector for a passenger conveyor. The human detector is capable of detecting states of falling, staying and approaching of users near an entrance with fewer sensors. The human detector comprises end cap portions which are formed on the end portions of skirt plates on the left and right sides of a stair and have first end face extending along the left and right ends of the stairs and second end face formed at a certain angle relative to the prolonging line, and a detection unit arranged on the end cap portion of one skirt plate, either the left or right one, and on the corner portion between the first end face and the second end face. The detection unit emits laser in the detection scope within a preset horizontal angle with a set point as the center to detect objects within the scope. The human detector further comprises a detection control unit which detects the states of falling, staying and approaching of users near an entrance according to the detection results of the detection unit. The detection scope is set as expanding towards the stair side relative to the vertical direction of the first end faces, and expanding towards the opposite side of the stair relative to the vertical direction of the second end faces.
