PURPOSE: To divide powdery/granular body into a desired division number, and improve the accuracy by rotating either one of a feeder or division disk in response to the working content.

CONSTITUTION: When a subdivision packing quantity of a powdery medicine is divided into a specified number, a feeder 30 rotates together with a feeder table 20 by starting of a motor 25, and a division disk 10 side is kept under a stationary condition. While the feeder table 20 is rotating by a set speed, the powdery medicine is sent out from a gutter drop port of the feeder 30 by a fixed flow velocity, and divided into division measures 12 in order. At a position where a stopper arm 23 comes into contact with a stopper 24, rotation of the feeder table 20 stops. The division disk 10 is rotated, and a packaging mechanism 40 is operated, a plate valve 14 is opened, and the powdery medicine contained in division measures 12 is sent to a division packing operation part of the packaging mechanism 40 in order, and is packaged by one pack at a time. When powdery medicine is divided into all the division measures 12 of the division disk 10, a driving motor 19 for the division disk 12 is driven. A specified quantity of powdery medicine is placed in the feeding hopper part of the feeder 30, and the powdery medicine is fed while the division disk 10 is rotated by a rotational speed which is faster than the normal speed.
