PROBLEM TO BE SOLVED: To provide a medicine supply device capable of surely supplying medicines such as tablets and capsules having different shapes and sizes one by one. A drug supply device includes a transfer path for transferring a drug, a movable restricting body that restricts a size of a region defined in the transfer path, a detection unit that detects a drug that has passed through the region, and a restrictor. A central control unit 83 that moves the body and arranges the body at a predetermined position, and a memory that stores, as drug information, the position of the regulator that allows the drug to pass through the region for each of a plurality of types of drugs having different shapes or sizes .. The central control unit moves the regulation body so that the area becomes larger, and the first position adjustment for arranging the regulation body at the position of the regulation body when the detection unit detects the medicine and the medicine information stored in the memory It is possible to execute the second position adjustment for arranging the regulation body based on the above. [Selection diagram] Fig. 11【課題】形状や大きさが異なる錠剤やカプセル剤などの薬剤を１個ずつ確実に供給可能な薬剤供給装置を提供する。【解決手段】薬剤供給装置は、薬剤を移送する移送経路と、移送経路の定められた領域の大きさを規制する可動式の規制体と、領域を通過した薬剤を検出する検出部と、規制体を移動させて所定位置に配置する中央制御部８３と、形状又は大きさが異なる複数種類の薬剤毎に、薬剤が領域を通過可能な規制体の位置を薬剤情報として記憶したメモリとを備える。中央制御部は、領域が大きくなるように規制体を移動させ、検出部が薬剤を検出した時の規制体の位置に、規制体を配置する第１位置調整と、メモリに記憶された薬剤情報に基づいて規制体を配置する第２位置調整とを実行可能である。【選択図】図１１
