PURPOSE: To reduce the rate of wasteful stop to enhance the efficiency of overall group control by providing a plurality of landing buttons at each landing, setting car sorting requirements, and selecting and sending, by use of a car sorting means, a car suited to the sorting requirements. CONSTITUTION: Up buttons A1 -C1 , and down buttons A2 -C2 , for which sorting requirements are set such that the degrees of jamming in a car are 100% or less, 50% or less, and 20% or less, are placed at the landing of each story. A group control means 11 selects an optimum car in response to a landing call registered by means of landing buttons A-C at that story, and generates an allotment signal to either of first to fourth car controllers 12-15. However, a car sorting means 16 compares the degree of jamming in the car required by the landing buttons A-C with current in-cage jamming information input from the controllers 12-15, and if they are coincident, responds to the landing call; if they are not coincident, the allotment is canceled, and the optimum car is re-selected. Thus, the rate of wasteful stop can be reduced, and the efficiency of overall group control can be enhanced. |
