Floors are each provided with: a hall registration device that places a plurality of car calls for moving a car to destination floors different from one another; and a display device that displays the car that has been assigned the plurality of car calls. Limit value setting means sets, for each of the plurality of floors separately, a limit value for limiting a count of the plurality of car calls that can be assigned to the same car. Count-up means obtains, when a new car call is made, a call count of the each car by a given method, based on information about the plurality of car calls that have been assigned to the car. Candidate car selecting means compares the limit value set to a floor where the new car call is made and the call count of the each car, to thereby select, as a candidate car, the car to which the new car call can be assigned from among the cars.
