PROBLEM TO BE SOLVED: To improve a tablet cassette compatible with a single rotation type tablet feeder which is detachable and easy to be replaced so that it can be commonly used for various medicines. SOLUTION: The container portion 20 that randomly stores tablets and the alignment board 40 that defines a plurality of compartments 67 therein are provided, and the tablets that have fallen into the compartments 67 are rotated by the axis rotation of the alignment board 40. In the tablet cassette 10 that is sequentially dropped from the discharge port 28 at the bottom of the container portion 20, the aligning plate 40 is mounted on the inner insertion portion of the rotary transmission shaft 41 that penetrates the bottom portion 25 of the container portion 20 and that is located in the tablet storage space 22. The radial expansion/contraction mechanism 6080 and the radial expansion/contraction mechanism 90 are provided. The circumferential expansion/contraction mechanism 6080 can expand/contract in the circumferential direction by interlocking a plurality of compartments 67. The plurality of compartments 67 can be interlocked with each other to expand and contract in the radial direction. [Selection diagram]【課題】着脱式で付け替え容易な一重回転タイプ錠剤フィーダ対応の錠剤カセットを種々の薬剤に共用しうるように改良する。【解決手段】錠剤をランダム収容する容器部２０と、その中で複数の区画室６７を画成する整列盤４０とを備え、整列盤４０の軸回転にて区画室６７に落ち入った錠剤を容器部２０の底部の排出口２８から逐次落下させる錠剤カセット１０において、整列盤４０が、容器部２０の底部２５を貫く回転伝動軸４１のうち錠剤収容空間２２に位置する内挿部分に外装された周方向拡縮機構６０８０と径方向拡縮機構９０とを具備しており、周方向拡縮機構６０８０が、区画室６７を複数連動させて周方向に拡縮しうるものであり、径方向拡縮機構９０が、区画室６７を複数連動させて径方向に拡縮しうるものである。【選択図】 図１
