A tablet cassette in which a tablet is not discharged during a mounting or dismounting operation of the tablet cassette. The tablet cassette (1) incorporates a rotor (6) having pocket portions (7) for holding tablets (T). When the tablet cassette 1 is mounted on a mount base (2), rotation of the rotor (6) causes the tablets (T) held in the pocket portions (7) to be discharged though a discharge port (8). The tablet cassette (1) includes a press member (16) which is pressed when the tablet cassette (1) is mounted on the mount base (2) and a rotor reversing member (19) for reversing the rotor (6) by a predetermined quantity in conjunction with pressing of the press member (16).
To automatically eliminate clogging of tablets, a tablet filling device provides a cassette body including a tablet cassette, having tablets, a rotor having a groove for holding a tablet, and a discharge port for discharging the tablet held by the groove. The cassette body includes a worm gear in mesh with a gear fixed to a shaft of the rotor. A carrying member is adapted to approach the tablet cassette while holding a tablet container. The tablet filling device is equipped with a drive shaft engaged with the worm gear to rotate the rotor via the gear. The tablet container is carried to the tablet cassette by the carrying member and, when a rotation of the rotor stops halfway through dispensing of tablets, the worm gear is moved in the axial direction of the drive shaft of the carrying member to cause the rotor to make a reverse rotation.
