A vertical position and an entrance depth of a partitioning member are easily adjusted in accordance with the size of a tablet to be dispensed. Further, a rotor is easily demounted from a securement member fixed to a drive shaft. A side wall of a cassette body 2 is formed with a plurality of slits 27, through which at least one elastic bristle 39 penetrates, along a circumferential direction of the rotor 3. The slits extend in an axial direction of the rotor 3. A partitioning member 19 is movable along the slit 27 with the elastic bristle 39 penetrating through the slit 27. When a cap 241 is downwardly pressed, a pressing portion 243 presses a flexible portion 255 to thereby release the engagement between the flexible portion 255 and an engagement portion 259 and an elastic force of an arm portion 263 urges a rotor 221 upwardly.
