Abstract:
An elevator device automatically setting a current value of an interval between upper and lower cars vertically movable inside a car frame, including: a moving mechanism vertically moving the cars; a memory storing a current interval between the cars; a car interval change quantity detector detecting a change quantity of the interval between the cars; an adjustment mechanism adjusting the interval between the cars based on the stored car interval and the detected change quantity of the interval; an initial car interval detector detecting that the interval between the cars has reached an initial car interval; and a learning mechanism causing the moving mechanism to vertically move the cars until the initial car interval detector detects that the interval between the cars has reached the initial car interval to learn the car interval when the car interval is not stored in the memory, which is then stored in the memory.
