PROBLEM TO BE SOLVED: To provide a medicine supply device and a medicine supply method, improving the supply accuracy of a medicine.SOLUTION: A medicine supply device includes: a medicine supply means 3 supplying a medicine to a container a weight detection means 4 detecting a weight of the medicine to be stored in the container and a control means 5 controlling the medicine supply means 3 based on a detected weight value detected by the weight detection means 4. The weight detection means 4 sequentially imparts the detected weight value to the control means 5. The control means 5 determines an intermediate target weight value smaller than a target weight value, restricts the supply of the medicine once when the detected weight value exceeding the intermediate target weight value is imparted during the supply of the medicine, decides whether or not the sequentially imparted detected weight value has been stabilized in a restricted state thereof, and when having decided that the detected weight value is stabilized, controls the medicine supply means 3 to supply the medicine based on the target weight value and the detected weight value in a stable state thereof.COPYRIGHT: (C)2014,JPO&INPIT【課題】 薬剤の供給精度を向上することができる薬剤供給装置および薬剤供給方法を提供する。【解決手段】容器に薬剤を供給する薬剤供給手段3と、前記容器に収容される薬剤の重量を検出する重量検出手段4と、重量検出手段4によって検出される検出重量値に基づいて薬剤供給手段3を制御する制御手段5とを備え、重量検出手段4は、検出重量値を逐次に制御手段5に与え、制御手段5は、目標重量値よりも小さい中間目標重量値を決定し、薬剤の供給中に中間目標重量値を超える検出重量値が与えられたとき、薬剤の供給を一旦制限し、該制限した状態で、逐次与えられる検出重量値が安定したか否かの判定を行い、該検出重量値が安定したと判定したとき、この安定状態における検出重量値と目標重量値とに基づいて薬剤を供給するように、薬剤供給手段3を制御することを特徴とする薬剤供給装置。【選択図】 図1
