PROBLEM TO BE SOLVED: To provide a powder drug supply device 10 comprising simple division powder drug supply mechanisms 70-71 capable of transmitting quickly, powder drug to a supply destination, even when an amount of the divided powder drug is a minute amount.SOLUTION: The powder drug supply device 10 comprises: a storage hopper 61 having an on-off valve 62 for receiving powder drug which is fallen and discharged from a powder drug cassette (90) by a minute amount, and temporarily storing the powder drug and measurement means (52),(60) for determining a powder drug transmission amount of the powder drug, and division of powder drug is performed by opening and closing of the on-off valve 62. The powder drug supply device further comprises: a groove-shape tub-state member 70 which is disposed on a lower side of the storage hopper 61 in an inclined posture (inclination angle φ) which allows sliding down of the powder drug by self weight and an oscillation mechanism 71 for oscillating the member 70. In the oscillation of the groove-shape tub-state member 70, longitudinal direction movement of it is permitted, but movement in other directions is suppressed. In addition, oscillation speed which is obtained by dividing amplitude of the groove-shape tub-state member 70 in oscillation by a half period is set in a predetermined speed range. During division of powder drug, the oscillation speed is varied from a lower limit speed side to an upper limit speed side in the speed range.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】分割後の散薬が微量でもそれを供給先へ速やかに送れる簡素な分割散薬送給機構70~71を具備した散薬供給装置10を実現する。【解決手段】散薬カセット(90)から少しずつ落下排出した散薬を受け入れて一時貯留する開閉弁62付き貯留ホッパ61と、その散薬送出量を求める計測手段(52),(60)とを備えていて、開閉弁62の開閉にて散薬分割を行う散薬供給装置10について、受け入れた散薬を自重で滑落させる傾斜姿勢(傾斜角φ)で貯留ホッパ61の下方に設けられた溝形樋状部材70と、それ70を振動させる加振機構71とを設ける。溝形樋状部材70の振動について、その長手方向移動を許容するが他方向の移動は抑制するようにする。さらに、溝形樋状部材70の振動時の振幅を半周期で除した振動速度を所定の速度範囲に収める。また、散薬分割時に速度範囲内で下限速度側から上限速度側へ振動速度を変化させる。【選択図】 図1
