Since power is supplied to Fz from power supplies A and B, only the car position indicator lights 3F, 1, 3F, 3F, and 3F are lit, and the car position indicator lights installed on other floors are In this state, power is not supplied and the lamp does not turn on.

According to this embodiment, since the car position indicator light on the floor where the car is stopped for inspection is turned on, the power supply from power supplies A and B lights up all the car position indicator lights provided on that floor. Power supplies A and H
The power supply equipment is sufficient to cover this capacity, and the power consumption can be reduced, making it highly economical as well as eliminating the need to turn on all the car position indicator lights on other floors at the same time as in the past. Therefore, it is possible to prevent users waiting at landings on other floors from misunderstanding or misunderstanding that there is an elevator abnormality when all the displays are lit.

In addition, if an inspection operation switch D is provided inside the car, if you operate this inspection operation switch D every time you arrive at the floor to be inspected, the car position indicator light on the other floor will display the car position only at that time. When the car position indicator light is turned off and the inspection operation switch D is returned, the current car position can be displayed, eliminating the phenomenon of the car position being completely unknown during inspection on another floor. Even if the car is in a dormant state, users who are unaware of this can be informed that the car is not in a dormant state and is ready for operation.
