PROBLEM TO BE SOLVED: To simply adjust the width, depth, and tablet separation position of a guide groove of a rotor according to the size of tablets to be delivered.SOLUTION: There are included a plurality of movable pieces 13 that are movable in a radial direction of a rotor 3 and constitute a face in a radial direction of each of the rotors of a plurality of tablet guide grooves 88. A movable piece moving mechanism 15 that moves each of the movable pieces 13 is provided and allows the plurality of movable pieces to be radially moved according to sizes of tablets, thereby regulating depths of the plurality of tablet guide grooves. Furthermore, groove width regulating mechanisms 17, 18, 19 are provided that relatively move a side face on both sides of the tablet guide grooves in a circumferential direction of the rotor 3. Further provided are a tablet pressing member 20 that is elastically deformable so that it may enter the table guide groove from the open end of table guide groove of the rotor to press the tablet in the tablet guide groove; and a pressing member 4 that, when the tablet guide groove arrives at a position that corresponds to a tablet outlet provided in the cassette body, presses the tablet pressing member toward the table guide groove.【課題】払い出す錠剤の大きさに応じて、ロータの案内溝の幅、深さ、錠剤の分離位置を簡単に調整する。【解決手段】ロータ3の半径方向に移動可能な複数の可動片13により複数の錠剤案内溝88のそれぞれのロータの半径方向の面を形成する。可動片13を移動させる可動片移動機構15を設け、この可動編移動機構により、錠剤の大きさに応じて、複数の可動片を半径方向に移動させて複数の錠剤案内溝の深さを調整可能とする。また、錠剤案内溝の両側の側面をロータ3の周方向に相対的に移動させる溝幅調整機構17,18,19を設ける。さらに、ロータの錠剤案内溝の開口端から当該錠剤案内溝に進入して当該錠剤案内溝内の錠剤を押圧するように弾性変形可能な錠剤押さえ部材20と、錠剤案内溝がカセット本体に設けた錠剤出口に対応する位置にきたときに、錠剤押さえ部材を錠剤案内溝に向かって押し付ける押し付け部材4とを設ける。【選択図】図4
