Elevator device

An elevator device comprising:

• a car frame provided so as to be able to rise and descend in a shaft;
• an upper car vertically movably provided inside the car frame;
• a lower car vertically movably provided below the upper car inside the car frame;
• a driving device configured to vertically move both the upper car and the lower car inside the car frame;
• a memory configured to store a car interval that is a current interval between both the cars;
• a car interval change quantity detection device configured to detect a change quantity of the interval between both the cars;
• a control part configured to cause the driving device to vertically move both the cars to adjust the interval between both the cars based on the car interval stored in the memory and the change quantity of the interval between both the cars detected by the car interval change quantity detection device;
• initial car interval detection means configured to detect that the interval between both the cars has reached a predetermined initial car interval;
• and
• a learning part configured to, when the car interval is not stored in the memory, cause the driving device to vertically move both the cars until the initial car interval detection means detects that the interval between both the cars has reached the initial car interval to learn the car interval,
• wherein the memory stores the car interval learned by the learning part,
• wherein the driving device reduces a moving speed of both the cars inside the car frame as compared to that in a normal time in learning by the learning part.
