It is preferable that one end of the rotating shaft is configured to protrude from the end of the rotating body.
[0034]
The second rotating body 30 is movable in the axial direction by screwing the male screw portion and the female screw portion. However, the second rotating body 30 is constituted by a guide groove extending in the axial direction and a convex portion engaging with the guide groove. You may.
[0035]
Further, the second rotating body 30 is positioned at a predetermined position by the engagement between the positioning groove 24 extending in the axial direction and the ball member 34 urged inward. The positioning recess may be provided.
[0036]
Further, the fixing means is constituted by the magnetic body 36 provided on the flange portion and the ball member 37 urged outward, but may be constituted by only one of them. Further, the core 1b may be configured to protrude by a predetermined amount from the edge of the wrapping paper 1a around which the core material 1b is wound, and a structure for sandwiching the protruded edge may be provided.
[0037]
In the above-described embodiment, the second rotator 30 that is movable in the axial direction is disposed on the side of the base (the frame 8) of the fixed shaft 11. It may be located.
[0038]
In the above-described embodiment, the mounting member 15 and the first rotating body 26 are provided separately, but may be provided integrally.
[0039]
As described above, the core material mounting portion 10 in the medicine packaging device of the present invention can be variously modified.
