A rotor (4) is received rotatably in a cassette body (3) for receiving tablets. The rotor comprises a tablet guiding path (4b) formed between a slanted inner face (6a) of the cassette body and a slanted outer face(22a) of the rotor for guiding the tablets received in the cassette body to a tablet discharging hole (7) disposed to the cassette body. The rotor comprises a separating member (8) disposed above the tablet discharging hole of the cassette body for separating a space between a tablet at a bottom position and a tablet at an upper position, a tablet supporting pedestal (53) disposed elevatably to the tablet guiding path for supporting the tablet at the bottom position in the tablet guiding path and a height adjustment mechanism (50) for adjusting a tablet discharging height between the tablet supporting pedestal and the separating member. The height adjustment mechanism makes the tablet supporting pedestal elevate to a direction inclined to a rotation shaft of the rotor along the tablet guiding path.
