A combined weighing apparatus 1 includes: a dispersion feeder 3 which conveys an article A supplied from the outside; a load cell 3b which detects an amount of the article A loaded on the dispersion feeder 3; and a control unit 14 which sets a force of conveying the article A in the dispersion feeder 3 on the basis of a detection result of the load cell 3b and controls an operation of the dispersion feeder 3 and the control unit 14 sets the conveying force of the dispersion feeder 3 to be smaller than a current conveying force when a state in which a change amount of the loading amount of the article A on the dispersion feeder 3 is smaller than a threshold value is maintained for a predetermined time or more in the detection result of the load cell 3b.
