In a control apparatus for a passenger conveyor, passenger detecting devices provided on balustrades distinguish and monitor the absence/presence of a passenger within first zones on an entrance gate side and an exit gate side including floor boards of the entrance gate side and the exit gate side, and the absence/presence of a passenger within second zones on the entrance gate side and the exit gate side adjacent to and beyond the first zones, covering the first zones. When a passenger is detected in the second zone on the entrance gate side in a standby mode, a mode switching circuit switches the operating mode to an intermediate mode, and when a passenger is detected in the first zone on the entrance gate side in the intermediate mode, the mode switching circuit switches the operating mode to a conveying mode.

Control apparatus for passenger conveyor and passenger detecting device

An escalator system has a plurality of steps connected to form an endless loop having a load-bearing run and a return run and circulatingly driven along a circulating path defined on a main frame. A movable member mounted on at least one of the steps is movable to an elevated position on the level of a tread of the step in front of that particular step in the load-bearing run. An operating mechanism is connected to the movable member for elevating the movable member. The operating mechanism comprises first and second racks mounted on the main frame at end portions of the loop. A forward-rotation pinion is mounted on the step with the movable member or on the step next to the step for engagement with the first rack, and a reverse-rotation pinion is mounted on the step with the movable member or on the step next to the step for engagement with the second rack. A drive force transmitting mechanism is connected to the operating mechanism for driving the operating mechanism in different directions by the forward-rotation pinion or the reverse-rotation pinion.
