Will end up. Conventionally, in consideration of such a slightly protruding drug, the stop position of the partition plate 14 is finely adjusted to a position slightly ahead of the designed partition plate position shown in FIG. 7 to adjust the protruding amount of the drug. The method of doing is adopted. Alternatively, even if the partition wall at a specific position is formed to have a slightly larger width and the partition plate stops at the same position as the position where the partition plate stops with respect to the other partition walls, the drug that has squeezed out must always be retained at the partition wall at the specific position. Consideration is given so that the entire amount can be accommodated.

However, in the former adjusting method, it is necessary to accurately adjust the moving amount of the partition plate with respect to the dividing rod at the position where the partition plate is stopped, and even if the partition plate is stopped at the correct position, the protruding amount is completely zero. You cannot do it. Further, in the latter adjusting method, since the dividing rod at a specific position must be designed large, it is necessary to form a divider having a special shape with respect to the dividing rod having the same capacity, which is costly and cumbersome to manufacture. There's a problem.

In consideration of the above problems, the present invention provides a range of divided containers in which a drug is dropped by providing a simple member without finely adjusting the position of the partition plate in the V-container when the opening / closing plate is opened. An object of the present invention is to provide a drug dividing device in which a drug does not flow out to a container portion adjacent to the.

It is equipped with a container and a dividing container consisting of a plurality of small containers arranged below the V container in parallel along the groove, and stores the drug in the range of the groove defined by the partition plate and evenly divides the drug in the V container. A partitioning auxiliary plate that closes the gap between the opening / closing plate and the front lower part of the partition plate when the opening / closing plate is abutted against the lower front part of the partition plate to close the groove The drug dividing device is characterized by being provided along the plate.

According to the medicine dividing device having such a structure, when the medicine is dropped from the V-shaped container into the dividing container, the medicine in the dividing container is dropped within a predetermined range in which the medicine should be dropped, and the lower gap of the partition plate is outside the predetermined range. The drug will not flow out. Close the opening / closing plate and stop the partition plate at a predetermined range position to set a fixed amount of the drug to V
After leveling over the entire reservoir in the groove of the box, open the open / close plate and drop it into the split container.

At this time, the opening of the opening / closing plate causes the auxiliary partition plate to move so as to close the gap formed between the lower part of the front surface of the partition plate and the opening / closing plate, and the gap is closed. Therefore, a part of the dropped medicine does not flow out from the gap to the container portion adjacent to the predetermined range of the divided container.
