Powder (b) cut and attached to tablet pieces (T1, T2) can be removed smoothly. A tablet dividing feeder (A1) cuts and divides a tablet (T) in a receiving pocket into two halves with a fixed blade as a rotor rotates. Powder removing plates (64a, 64b, 66) are installed in a tablet supplying passage (14) of the feeder. The powder removing plate (64b) is vibrated by a vibration motor (71) to peel the powder (b) attached to the tablet on the powder removing plate and drop the powder (b) from a slit (a). The peeling operation is performed by temporarily leaving the tablet pieces (T1, T2) between the powder removing plates (64a, 64b). The powder removing plate (64b) is fluctuated by a plunger, and the tablet pieces may be left and dropped due to the fluctuation. The tablet piece drops along the powder removing plate (66), and the attached powder is peeled to be guided to a packaging process through a supply opening (90).
