PURPOSE:To secure a time for getting on again even if a car stops on a nonstop floor and a passenger gets off so as to prevent the passenger from being stuck on the nonstop floor by prolonging a closing time limit of a car door until a call is registered on other floors than the nonstop floor if the car stopped on the nonstop floor. CONSTITUTION:If a switch 2S is closed when the second floor is set as a nonstop floor, a relay 2F is energized, and a contact 2Fb1 is opened, while a call detecting relay 512 on the second floor cannot be energized even if a button 2Y is pressed, and as a result, the second floor becomes a nonstop floor. However, a call is effective as it is registered before the switch 2S is closed, so that the car stops on the second floor and its door starts to open if a call is made for the second floor. When the door finishes opening, a door close preventing relay TS is energized, because a contact 2Fa2 is closed. A door close commanding timer T cannot count as a contact 2Fb2 is opened, and the door closing relay 101 is not energized, and as a result, a door open condition is maintained. In other words, a door close time limit is prolonged, and passengers are prevented from being stuck. |
