Abstract
A powder-weighing apparatus and a powder-weighing method having a high weighing speed and a high weighing accuracy are provided. For weighing powder within a predetermined allowable range of a target weight Wt, the powder-weighing apparatus may be configured to have a primary-charge weighing portion for weighing and retaining a weight Wof primary-charge powder smaller than the target weight Wt and at least two auxiliary-charge weighing portions each for weighing and retaining a weight Wof auxiliary-charge powder within a predetermined range of an auxiliary-charge weight Ws. When a weight Wof the powder retained in the primary-charge weighing portion is smaller than a lower limit of the predetermined allowable range of the target weight Wt, one of the two weights Wmay be selected so that a sum (W+W) becomes closest to the target weight Wt, and the powder retained in the primary-charge weighing portion and the powder retained in the selected auxiliary-charge weighing portion are discharged.
