In a control apparatus for a passenger conveyor, passenger detecting devices provided on right and left 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 the outside of the first zones so as to cover the first zones. The control apparatus body controls operation of the passenger conveyor in accordance with a plurality of operating modes including a standby mode for stopping operation for standby, an intermediate mode switched over from the standby mode, a conveying mode switched over from the intermediate mode for conveying a passenger and an alarm mode for alerting a passenger who is about to enter from the exit gate side that the conveyor is operating in the opposite direction. In the case where a passenger is detected in at least one second zone on the entrance gate side and the exit gate side in the standby mode, the mode switching circuit switches the operating mode to the intermediate mode, and in the case where 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 the conveying mode. Also, in the case where a passenger is detected in the first zone on the exit gate side in the intermediate mode, the mode switching circuit switches the operating mode to the alarm mode. <IMAGE> |
