PROBLEM TO BE SOLVED: To provide a weighing instrument which improves a weighing speed and weighing accuracy of a material to be weighed, in comparison with conventional examples.SOLUTION: In a weighing instrument 100, such a combination of moderate amount supply weighing hoppers 64, 65, 66, and 44 is obtained by combination calculation that the total of weights of a material to be weighed in the moderate amount supply weighing hoppers 64, 65, 66 and 44 is closest to a prescribed combinational target weight, and the material to be weighed in the moderate amount supply weighing hoppers selected as the combination is selectively discharged, and the weighing speed and the weighing accuracy of the material to be weighed are adjusted by a volume supply weight MB, the combinational target weight, and a small amount supply discharge weight MR. |
