PROBLEM TO BE SOLVED: To provide a pharmaceutical packaging machine, even when a user tries to pull out a currently-locked powder distribution/division device, preventing a shelf board or the like of the powder distribution/division device from being easily deformed.SOLUTION: A pharmaceutical packaging machine is so configured that an upper powder distribution/division device 20, as well as a lower packaging device 15, can be pulled out forward from a housing 13. Further, when a reinforcement member 22 is attached to the lower surface of a shelf board 21 of the powder distribution/division device 20, a reinforcement member 22a is disposed only at the outside of a hole font/back belt-like-part lower surface 23 that is located on the upper side of a loading hopper 16 in front view. A mechanical lock mechanism 30 is provided for preventing simultaneous pulling-out of the packaging device 15 and the powder distribution/division device 20. Furthermore, a plurality of lock mechanisms 30 are provided, and the lock mechanisms 30 are disposed at both of the leftward position and rightward position of the loading hopper 16 in the front view.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】ロック中の散薬分配分割装置を引き出そうとしても散薬分配分割装置の棚板等が変形し難い薬剤分包機を実現する。【解決手段】下側の包装装置15に加えて上側の散薬分配分割装置20も筐体13から前方へ引き出せるようにするとともに、散薬分配分割装置20の棚板21の下面に補強部材22を付設する際には正面視で投入ホッパ16の上方に位置することある穴前後帯状部下面23部分の外にだけ補強部材22aを配置し、包装装置15と散薬分配分割装置20との同時引出を阻止する機械式のロック機構30を設け、更に、ロック機構30は、複数にし、それら30を正面視で投入ホッパ16の左方位置と右方位置との何れにも配置する。【選択図】 図1
