  • Patent number: 8209942
    Abstract: There is provided a medicine packing device, which prevents a free end of a bottom plate of a tablet dispensing measure from tilting due to its own weight. A bottom plate 43 is provided at a lower opening of a tablet dispensing measure 42. The bottom plate 43 includes a pin 44 at its base end. A leading end of the bottom plate is a free end. When the tablet dispensing measure 42 reaches corresponding stepped portions 37a to 37d by a movement of a tablet dispensing member 36, an opening protrusion 144b of a fixed plate 37 is fitted to an opening recess 43c of the bottom plate 43 and thus the bottom plate 43 pivots about the pin 44 from a closed position to an open position. If the bottom plate 43 moves to the open position, then tablets in the tablet dispensing measure 42 drop.
