Abstract:

PURPOSE: To kindly guide waiting users even if there is indication of an allotted car behind them by turning OFF a direction indication lamp when the allotted car is located on the opposite side and lighting opposite indication lamps on both sides of an operated landing button.

CONSTITUTION: When the up-button of a landing button 13 is pressed and the car G of a 7th elevator is allotted to this landing call, since an allotment signal 29aG becomes H and the output of an OR gate 32C becomes H, the output of an AND gate 38C becomes L. Accordingly, the output of an AND gate 36C becomes L, and an upward indication lamp 21C is turned OFF. At this time, since the output of a NOR gate 30C is H, the output of an AND gate 33C becomes H. Since a landing call registration signal 13a is H, the output of an AND gate 35C becomes H, and the output of an OR gate 31 also becomes H. Thus, the opposite indication lamps 23C and 23D of 3rd and 4th elevators indicate opposite sides, and the location thereof behind the allotted car is informed.
