PASSENGER CONVEYOR

A power supply circuit of a passenger conveyor converts includes an electrolytic capacitor and a control power supply device configured to supply an electric power to a charging circuit configured to charge the electrolytic capacitor. A storage battery is disposed between a converter and an inverter in parallel with the electrolytic capacitor. When an operation of the passenger conveyor is stopped in response to a key operation, the power supply to the control power supply device is shut off. When the operation of the passenger conveyor is resumed in response to a key operation, a DC electric power charged in the storage battery is supplied to the inverter, to thereby allow the passenger conveyor to resume the operation.
