FIG. 2 shows a schematic configuration of an embodiment of the powder medicine container 1, wherein the stock portion 3, the supply portion 4 and the discharge portion 5 each have a void having a required inner volume and shape. Moreover, the vacant space of the stock part 3 and the vacant space of the supply part 4 communicate at least partially, and the vacant space of the supply part 4 and the vacant space of the discharge part 5 communicate at least partly. However, since various designs are possible for the inner volume, the shape, the location and the form of communication, etc. of these voids, specific illustration is omitted. For example, as an example, the supply unit 4 is arranged below the stock unit 3, the discharge unit 5 is arranged further below the supply unit 4, and the lower end of the empty space of the stock unit 3 and the empty space of the supply unit 4 are arranged. The upper end of the place communicates with the lower end of the empty space of the supply unit 4,
It is configured to communicate with the upper end of the empty space of the discharge part 5, so that the powdered medicine in the empty space of the stock part 3 will enter the empty space of the supply part 4 as long as it falls smoothly, and from there, it will be smoother. It is possible to design it so as to pass through the void of the supply part 4 and enter the void of the discharge part 5 only if it falls to the inside. An appropriate discharging member 6 is provided in the empty space of the discharging portion 5, and an appropriate shutter 7 is provided at the discharging port formed at the appropriate position in the empty space. Discharge member 6
Can be constituted by, for example, a screw formed by a spiral flange protruding around the spindle, and in this case, the void is formed in a cylindrical shape, and the screw-shaped It is preferable to dispose the discharge member 6, and it is preferable to form a discharge port at the tip of this cylinder and dispose the shutter 7 there.

Therefore, when the discharge member 6 is rotated by the motor 8 and the shutter 7 is opened by the actuating member 9, the powdered medicine in the cylindrical void of the discharge portion 5 moves toward the discharge port and is discharged from the discharge port. When the discharge member 6 is stopped from rotating and the shutter 7 is closed, the movement and discharge of the powdered medicine in the discharge unit 5 are stopped. Further, an appropriate stirring member 10 can be provided in the empty space of the supply unit 4. The stirring member 10 can be constituted by, for example, a scraper formed by protruding a plurality of arm members around the spindle as a center, and the stirring member 10 is configured to rotate the stirring member 10. The appropriate motor 11 is connected. Therefore, when the stirring member 10 is rotated by the motor 11, the powdered medicine in the empty space of the supply section 4 is smoothly supplied into the cylindrical empty space of the discharge section 5 while being stirred, and at the same time, in the empty space of the supply section 4. The powder is supplied from the helstock unit 3. Further, the powdered medicine in the empty space of the stock portion 3 gradually moves toward the empty space of the supply portion 4 according to the powdered medicine discharge operation of the discharge portion 5 and the powdered medicine supply operation of the supply portion 4 accompanied therewith, In order to carry out this movement smoothly, it is desirable that the cross-sectional area of the vacant space of the stock portion 3 be gradually increased from the upstream side to the downstream side, or at least be approximately the same from the upstream side to the downstream side. However, the upstream side can be made larger than the downstream side for the purpose of stocking a large amount of powdered medicine as much as possible with the limited external dimensions of the stock portion 3 and the purpose of suppressing the installation space of the powdered medicine container 1. Supply unit 4 if required
It is indispensable to provide an appropriate stirring member 12 on the stock portion 3 itself, separately from the stirring member 10 of FIG. The stirring member 12 may be rotated by an independent dedicated motor, but the stirring member 1 of the supply unit 4 may be rotated.
