PURPOSE:To reduce the cost of a weighing instrument and increase its accuracy by combining the weighed values of objects to be weighed obtained on the basis of the output signals of a plurality of the weighing instruments at every receiving place. CONSTITUTION:A plurality of objects to be weighed are fed via a feeder 11, a circular feeder 12, feeders 131-13n and intermediate hoppers 141-14n to weighing hoppers 141-14n to be accommodated therein again from discharge gates 151, 153... and via the gates 152, 154... to the hoppers 162, 164... to be accommodated therein. Thus, the objects to be weighed are accommodated in the hoppers 161-16n and the weights of the objects to be weighed in the hoppers 161-16n are stored 24 by weight signals from weighing instruments 171-17n. The combined weight of a prescribed number of the weighing hoppers is calculated in a combinational calculating unit 25a on the basis of the stored weight signals. The combination of the weighing hoppers wherein difference from a set weight that has been set 25b is minimum is discriminated in a judging unit 25c and combination selection signal is fed to a discharge controller 23. The controller 23 opens a discharge gate specified by the combination selection signal and the object to be weighed is packed 21 via a chute 19.
