PROBLEM TO BE SOLVED: To provide a control device of a passenger conveyor in which a volume of wiring for detecting which safety device is operated is reduced. SOLUTION: The control device of a passenger conveyor includes a plurality of detection contact points which are connected in series to a voltage supply source and opened according to the operation of each of a plurality of safety devices installed in the passenger conveyor, a plurality of voltage lowering circuits which are installed in proximity to the plurality of detection contacts, respectively, and connected in parallel to the respective plurality of detection contact points, and a monitoring device for detecting which safety device is operated by detecting a voltage at the end of the detection contact point farthest from the voltage supply source at the opposite side of the voltage supply source.
