PURPOSE: To secure safety at boarding-alighting time by arranging a lighting system to illuminate a boarding-alighting port part above a landing elevator hall doorway, lighting it when a landing door is opened, and putting it out when the door is closed. CONSTITUTION: A car reaches the object floor, and when a landing door 1 is opened, a contact point Da is turned on. Therefore, a circuit of electric power supply P - a contact point Ha - the contact point Da- a relay R - electric power supply Nis constituted, and the relay R is excited, and a contact point Ra is turned on, and a circuit of the electric power supply P - the contact point Ha - the contact point Ra - a lighting system 4 the electric power supply N is constituted, and the lighting system 4 is lighted, and a boarding-aligting port part 2 is illuminated. Boarding and alighting of passengers are finished, and when the landing door 1 is closed, the contact point Da is turned off. Therefore, circuit constitution of the electric power supply P - the contact point Ha - the contact point Da - the relay R - the electric power supply N is lost, and the relay R is demagnetized. Therefore, the contact point Ra is turned off, and circuit constitution of the electric power supply P - the contact point Ha - the contact point Ra the lighting system 4 - the electric power supply N is also lost, and the lighting system 4 is put out. Therefore, safety at boarding-alighting time can be secured. |
