PROBLEM TO BE SOLVED: To enhance the weighing accuracy by reducing vibration noise included in a weighing signal as much as possible.SOLUTION: A weighed object 13 is supplied to mount bases S1 to S16 of a weighing unit rotating in a circumferential direction, a weight value of the weighed object 13 is obtained at weight obtaining positions I1 to I7 right before a plurality of sorting positions (1) to (7) corresponding to a plurality of weight ranks of the weighed object 13, a filter for response time corresponding to each of the weight obtaining positions I1 to I7 is set on the basis of the set rotational speed of the weighing unit, and each weight value is obtained from a weighing signal filter-processed by each filter. |
