PURPOSE:To improve operability, by moving auxiliary hoppers to discharge receiving positions from measuring hoppers and positions, which are deviated from the receiving positions. CONSTITUTION:Auxiliary hoppers 12 are provided in correspondence with measuring hoppers 11 in a combination scale. When the hopper 12, which is selected in combination, discharges a material and becomes vacant, a measured material is discharged from the upper hopper 11. When the hopper 11, which is not selected in combination, is located above the hopper 12, in which a material that is not selected in combination is contained, an air cylinder 13 is actuated and the hopper is moved to 12a shown by an imaginary line. Then the material in the hopper 11 is discharged. When the hopper 12, which is selected in combination, is located under the hopper 11, which is selected in combination, the discharge operations are performed by both hoppers. The material in the hopper 11 is discharged on a conveyer 14 through the hopper 12. Since one half the number of the hoppers, which take parts in combination, is the measuring hoppers, the number of the measuring systems is few. Since the material is inputted to the measuring hoppers, number of input positions becomes few, operability is good and costs can be reduced.
