PROBLEM TO BE SOLVED: To materialize a measuring/dividing type powdered drug supply device by which powdered drug discharged little by little from a powdered drug cassette can be quickly and accurately divided in minute quantities with an opening/closing hopper.SOLUTION: With a stop valve 61 closed, and after a first bearing member 71 for a weight measuring target is made to support a measurement hopper 60, powdered drug continuous delivery parts 20-52 are made to discharge powdered drug and, at the same time, weight measurement is performed by a weight measuring member 74. On the basis of the weight measurement result, upon detection of completion of powdered drug discharge in one divided amount, the powdered drug continuous delivery parts 20-52 are made to stop discharging of the powdered drug. Simultaneously, a second bearing member 72 is made to support the measurement hopper 60 by the bearing member switching function of an elevation mechanism 73. Then, with the stop valve 61 opened, the measurement hopper 60 is knocked by a striker 81. Also, the stop valve 61 and a driving mechanism 62 for hopper opening/closing are designed to be attachable/detachable. Further, a striking mechanism 80 is put outside the weight measuring target.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】散薬カセットから少しずつ排出された散薬を開閉式ホッパにて迅速かつ正確に微量分割しうる計量分割式の散薬供給装置を実現する。【解決手段】開閉弁61を閉状態にするとともに重量測定対象の第1支承部材71に計量ホッパ60を支承させてから散薬連続送出部20~52に散薬排出を行わせつつ重量計測部材74にて重量測定を行い、その重量測定結果に基づいて一分割量の散薬排出の完了を検知すると散薬連続送出部20~52に散薬排出を停止させるとともに昇降機構73の支承部材切替機能にて第2支承部材72に計量ホッパ60を支承させてから開閉弁61を開状態にするとともに叩打子81で計量ホッパ60を叩くようにする。また、開閉弁61とホッパ開閉駆動機構62とを着脱式にする。さらに、叩打機構80を重量計測対象外に置く。【選択図】 図1
