PROBLEM TO BE SOLVED: To provide a combination weighing apparatus capable of improving weighing accuracy.SOLUTION: A combination weighing apparatus 1 comprises: a plurality of weighing hoppers 40 that accommodates and discharges objects to be weighed; a weight detection section 42 that detects a weight value of each of the weighing hoppers 40; a weighing value correction section 62 that calculates a corrected weighing value W2 by subtracting a weight correction value E1 obtained from a weight value M2 detected for each of the weighing hoppers 40 immediately before an object to be weighed is accommodated with a zero point correction value V0 (V1) as a reference from a weighing value W1 of the object to be weighed obtained from the weight value M1 detected for the weighing hopper 40 accommodating the object to be weighed with the zero point correction value V0 (V1) as a reference; and a computing section 63 that selects a combination of the objects to be weighed so that a value of one weighing value W2 or a value obtained by combining a plurality of corrected weighing values W2 among the corrected weighing values W2 of each of the weighing hoppers 40 is within an allowable range with a target value as a reference. |
