According to the bottom plate opening / closing member 37, when the movable collecting container 2 is moved to perform the packaging process, if the bearing 40 is at the upper position as shown in FIG.
The abutting portion 25c of No. 5 abuts. Since the shaft 40a is movable between the first positioning recess 41a and the second positioning recess 41b, as shown in FIG. 6B, the arm member 39 rotates about the support shaft 39a and the bearing 40 moves. Move to the lower position. As a result, the bottom plate 25 is not opened by the bearing 40 during the movement of the moving collection container 2. When the moving collecting container 2 has moved through the position shown in FIG. 6C and the bottom plate opening / closing member 37 has finished moving,
As shown in (d), the pressing piece 36 presses the contact piece 42 to rotate the arm portion 15 to the opposite side and position the bearing 40 at the upper position.

Then, when removing the drug remaining in each of the divided containers 19, the cleaner device 3 is driven to move the movable collecting container 2 in the opposite direction. At this time, since the bearing 40 has already returned to the upper position, when each divided container 19 is positioned below the suction port 34a of the duct 34,
The abutting portion 25c of the bottom plate 25 rides on the bearing 40 and rotates to sequentially open the lower end opening of the divided container 19 by a predetermined dimension.

In each of the above-described embodiments, the rotation angle of the bottom plate 25 is suppressed to form a slight gap below the divided container 19 to effectively remove the residual drug. The rotation angle of the bottom plate 25 is not particularly limited as long as the only purpose is to remove the remaining medicine (therefore, it may be fully opened). In this case, for the rotation of the bottom plate 25, a configuration similar to that of the first opening / closing device 4a may be adopted. In addition, the suction port 34 of the duct 34 of the cleaner device 3
You may make it cover all the upper opening part of the division container 19 with a.
