Abstract:
In an elevator apparatus, a reference position switch is a usually closed switched that is opened by a car moving to a reference position. A detected body is installed inside a hoistway. A detected body detector that detects the detected body is disposed on the car. A car position detecting portion stores as detected position information of the detected body an amount of movement of the car from where the detected body is detected until the car is detected by the reference position switch by a learning run that is implemented in advance. After completion of the learning run, the car position detecting portion detects the car position based on information from the detected body detector, the stored detected position information, and information from a movement detector that outputs a signal that corresponds to an amount of movement of the car.
