PROBLEM TO BE SOLVED: To prevent undesired leakage of granules and granule-biting in delivery means.SOLUTION: A delivery mechanism 35 includes a shutter member 50 capable of sliding freely from a closed state for blocking a supply route 36 and an open state for forming a passing opening in the supply route 36, and a solenoid 41 that changes over the shutter member 50 between the closed state and the open state. The shutter member 50 can slide freely so as to cross a side wall 46 at one side in a wall part forming the supply route 36, and a first clearance 62 through which mainly powder among granules is allowed to pass is disposed between a top face 50A of the shutter member 50 and an end of the side wall 46 at the one side.COPYRIGHT: (C)2014,JPO&INPIT【課題】粉粒体の望ましくない漏れを防ぎつつ、繰出し手段における粉粒体の噛み込みを防止できるようにする。【解決手段】繰出し機構35に、供給経路36を閉塞する閉状態と供給経路36内に通過用開口を形成する開状態とにわたりスライド移動自在なシャッター部材50と、シャッター部材50を閉状態と開状態とに切り換えるソレノイド41と、が備えられ、シャッター部材50が、供給経路36を形成する壁部のうち一方側の側壁46と交差するようにスライド移動自在とされており、シャッター部材50の上面50Aと一方側の側壁46の端部との間に、粉粒体のうち主に粉体の通過を許す第一クリアランス62が設けられてある。【選択図】図6
