The device also includes a position detecting unit configured to detect a position of an elevator car within a shaft, a storage unit configured to store the position of the elevator car within the shaft and an acceleration of the elevator car in association with each other. The device also includes a control unit configured to extract the acceleration in the lateral direction of the elevator car detected by the position detecting unit from the storage unit. The control unit also controls the drive unit so as to adjust the pressing force of the guide unit against the guide rail to a pressing force that is derived from at least the extracted acceleration in the lateral direction of the elevator car.

Abstract: When a specific destination floor call is made, the control unit assigns an elevator of which waiting time is within the reference time from the plurality of elevators to the specific destination floor call, the waiting time being a time from a time when the specific destination floor call is made to a time when the specific user can get on an elevator at the specific floor. Further, when a general destination floor call is made, the control unit assigns one of the plurality of elevators in response to the general destination floor call such that an elevator of which waiting time to the specific destination floor call that is made after the general destination floor call is within the reference time is left.
