Abstract
In an elevator apparatus, a plurality of storage media are arranged in a hoistway so as to be spaced from one another in a hoisting direction of a car. In the car, reading device that reads information stored in the storage media is mounted. The storage media are arranged in the hoisting direction at intervals different from one another. A safety monitor is configured to: execute an operation for detecting two storage media; measure an interval between the detected storage media based on a signal from movement detector; compare the measured interval between the storage media with stored intervals of the storage media: and to grasp the position of the car by using a result of the comparison and the information of the storage media, when a position of the car cannot be grasped.
