PROBLEM TO BE SOLVED: To provide a weighing apparatus capable of accurately determining in a short time whether time change of weighed values is stable or not as compared with the case where the weighed values themselves are determined.SOLUTION: A weighing apparatus includes: a weighing part which outputs time change of the weighed values in accordance with the mass of articles inputted from the outside; and a control part which determines whether the time change of the weighed values is converged in a predetermined range at least using a first change amount which is the amount of change per unit time of the weighed amount outputted from the weighing part and a second change amount which is the amount of change per unit time of the first change amount.SELECTED DRAWING: Figure 4 【課題】計量値の時間変化が安定しているか否かを、計量値そのものを判定する場合と比べて短時間で正確に判定できる計量装置を提供する。【解決手段】計量装置は、外部から投入された物品の質量に応じた計量値の時間変化を出力する計量部と、前記計量部により出力された前記計量値の単位時間当たりの変化量である第１変化量、及び、前記第１変化量の単位時間当たりの変化量である第２変化量を少なくとも用いて、前記計量値の時間変化が所定の範囲に収束したか否かを判定する制御部と、を備える。【選択図】図４
