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

A control device for a passenger conveyor includes an upward moving device for moving the passenger conveyor upward, a downward moving device for moving the passenger conveyor downward, a detection device of detecting an anomaly of the movement of the passenger conveyor, an emergency stopping device for stopping the movement of the passenger conveyor by emergency stopping either the upward moving device or the downward moving device which is operated when the detection device detects an anomaly, a control device for operating the other of the upward moving device and the downward moving device after the emergency stopping device stops the passenger conveyor to forcibly move the passenger conveyor in a direction opposite to that in which it is moving before it is stopped, and a forcible operation stopping device for stopping the forcible movement of the passenger conveyor when the detection device is reset due to the passenger conveyor being forcibly moved by the control device.
