To provide a tablet cassette rotor capable of handling tablets of more shape and size with few parts, and further capable of dealing with automatic adjustment of the depth, width and partition position of the tablet guide path.SOLUTION: In a rotor 4 rotatably housed in a cassette body accommodating a tablet T and having a plurality of tablet guide paths 4b for guiding the tablets to a tablet discharge hole, in the tablet guide path inclined with respect to the rotation axis of the rotor The upper inclined inner surface 6a and the lower inclined outer surface 22c to raise and lower the rotor with respect to the cassette body so that the distance between the upper inclined inner surface and the lower inclined outer surface of the tablet guide path can be adjusted and below the partition member The tablet support table positioned and supporting the lowest tablet was raised and lowered so that the distance between the partition member and the tablet support table could be adjusted. The first movable member and the second movable member are rotated relative to each other so that the distance between the first vertical protrusion and the second vertical protrusion constituting the tablet guide path can be adjusted.(FIG.【課題】部品点数が少なく、より多くの形状と大きさの錠剤を扱うことができ、さらに錠剤案内路の深さ、幅、仕切位置の自動調整にも対応できる錠剤カセット用ロータを提供する。【解決手段】錠剤Tを収容するカセット本体に回転可能に収容され、錠剤を錠剤排出孔に案内する複数の錠剤案内路4bを有するロータ4において、錠剤案内路にロータの回転軸に対して傾斜する上部傾斜内面6aと下部傾斜外面22cを備え、カセット本体に対してロータを昇降させて、上部傾斜内面と錠剤案内路の下部傾斜外面との間の距離を調整可能にし、仕切部材の下方に位置し最下位の錠剤を支持する錠剤支持台を昇降させて、仕切部材と錠剤支持台との間の距離を調整可能とした。また、第1可動部材と第2可動部材を相対的に回転させ、錠剤案内路を構成する第1垂直突片と第2垂直突片との間の距離を調整可能とした。【選択図】図9
