<p>PROBLEM TO BE SOLVED: To provide a passenger conveyor capable of cutting off a control power source of a control circuit performing control of a motor.SOLUTION: A passenger conveyor has a cut-off circuit 104 being provided between a power source 105 and a control circuit 102 and cutting off a control power source by a cut-off switch CUT provided to the passenger conveyor. When an operator turns a key from a position of STOP to a position of CUT while the key is being inserted into a control panel or a key switch of the control panel and performs one-shot input so as to completely cut off the control power source of the control circuit 102 and a safety circuit 103, the cut-off switch CUT of the cut-off circuit 104 is brought into an OFF state, currents do not flow through cut-off relays PCR, and a first cut-off relay PCR1 and a second cut-off relay PCR2 are brought into OFF states. On this account, the control circuit 102 and the safety circuit 103 are not supplied with the control power source and consumption of standby power is eliminated.</p> |
