PURPOSE:To surely register a landing call and surely avert the collision between a user with a car or a car door. CONSTITUTION:A load detector 10 is installed on a landing floor 3. When the load detector 10 detects a load, a controller 13 recognizes a landing call, and operates a timer 12. The controller 13 carries out landing call registration, if the load detector 10 detects the load after the lapse of a specific time. Further, if it is detected that a car is landed and a door 1 is opened, the controller 13 operates the timer 12. The controller 13 prolongs the opening time of the door 1 if the load detector 10 detects the load after the lapse of a specific time, while if the load is not detected, a door opening/closing device 4 is operated to close the door 1. |
