(Problem) The width and depth of the guide groove of the rotor are easily adjusted according to the size of the tablet to be dispensed. (Solution) A plurality of tablet guide grooves (88) are arranged so as to be movable in the radial direction of the rotor (3), and a plurality of tablet guide grooves (88) form a radial surface of the rotor (3). The movable piece (13) and a movable piece moving mechanism (15) for moving the movable piece (13) in the radial direction of the rotor (3) are provided. Further, a groove width adjusting mechanism (17, 18, 19) for moving the side surfaces on both sides of the tablet guide groove (88) relatively in the circumferential direction of the rotor (3) is provided. [Selection] Figure 4(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、深さなどを簡単に調整する。(解決手段)複数の錠剤案内溝（８８）の各々にロータ（３）の半径方向に移動可能に配設され、錠剤案内溝（８８）におけるロータ（３）の半径方向の面を形成する複数の可動片（１３）と、可動片（１３）をロータ（３）の半径方向に移動させる可動片移動機構（１５）とを設ける。また、錠剤案内溝（８８）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。【選択図】図４
