PROBLEM TO BE SOLVED: To synchronously control another elevator based on the farthest elevator from a specified destination position to improve a follow-up property, by turning OFF an actuator of an elevator the positional deviation of which is out of a prescribed range relative to the position of the reference elevator, and turning ON actuators of an elevator the positional deviation of which is within the prescribed range and the reference elevator. SOLUTION: A control device 1 detects present positions of respective elevators 11, 12, 13, 14 with detectors D1, D2, D3, D4, sets the most slowly moving elevator as a reference elevator, derives deviations between this and the other three elevators, turns off voltage of an electric motor of the elevator positioning out of a synchronous control range relative to the reference elevator, and turns on the elevator positioning in the synchronous control range. Thus, the elevator approaching a destination position beyond the synchronous control range is turned off and decelerated based on the farthest elevator from the destination position to shorten a positional deviation for the reference elevator. In addition, the elevator positioning in the synchronous control range (including the reference elevator) is turned on to keep the synchronous control state.
