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 3 housing a tablet and having a plurality of tablet guide paths 4b for guiding the tablets to a tablet discharge hole, in the tablet guide path, with respect to the rotation axis of the rotor And has an inclined outer surface opposed to the inverted conical inclined inner surface of the cassette main body. The rotor is raised and lowered with respect to the cassette body so that the distance between the inverted conical inclined inner surface of the cassette body and the inclined outer surface of the tablet guide path can be adjusted. The tablet support table 47 which is located below the partition member and supports the lowest tablet is raised and lowered so that the distance between the partition member 8 and the tablet support table can be adjusted. The first movable member 50 and the second movable member 60 are relatively rotated so that the distance between the first vertical protrusion 53 and the second vertical protrusion 63 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】錠剤を収容するカセット本体3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し、カセット本体の逆円錐状の傾斜内面と対向する傾斜外面を備える。カセット本体に対してロータを昇降させて、カセット本体の逆円錐状の傾斜内面と錠剤案内路の傾斜外面との間の距離を調整可能にした。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47を昇降させて、仕切部材8と錠剤支持台との間の距離を調整可能とした。第1可動部材50と第2可動部材60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53と第2垂直突片63との間の距離を調整可能とした。【選択図】図9
