  The main elevators 56 to 59 can circulate in the shafts 52 and 53 in a fixed direction and can be stopped only on the fifth, tenth and fifteenth floors of the shafts 51 and 54. Therefore, the main elevators 56 to 59 are on standby at any of the fifth, tenth, and fifteenth floors in the shafts 51 and 54 when waiting for a command. In FIG. 1, the main elevator 56 is stopped on the 10th floor of the shaft 51. Further, the main elevators 56 to 59 are similarly operated by using the shafts 51 and 54 when a person gets on and off or when the main elevators 56 to 59 are temporarily retracted when overtaken by another main elevator. The sub elevators 61 to 68 move by interpolating between the floors where the main elevators 56 to 59 are stopped, and one sub elevator is installed in each interpolation range, and can be stopped for each floor. For example, the sub-elevator 64 moves only in the 1st to 4th floor interpolation range of the shaft 54.
