Abstract
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.
