PROBLEM TO BE SOLVED: To provide a feeding device capable of precisely feeding grains in each prescribed amount even when the amount of the grains to be fed is increased or decreased.SOLUTION: The feeding device for feeding the grains in each prescribed amount is constituted so that when a perforated plate 60 is rotated and a perforated plate hole 61 of the perforated plate 60 is positioned over a feeding port 55a of a lower member 55, the perforated plate hole 61 of the perforated plate 60 may communicate with the feeding port 55a of the lower member 55, and the grains accumulated in the perforated plate hole 61 of the perforated plate 60 may be fed from the feeding port 55a of the lower member 55. The feeding device is constituted so that the volume of the perforated plate hole 61 of the perforated plate 60 may be increased or decreased by allowing the perforated plate hole 61 of the perforated plate 60 to be expanded or contracted in the axis center direction of the perforated plate hole 61.COPYRIGHT: (C)2013,JPO&INPIT【課題】繰出される粒状物の量を増減させても、より確実に粒状物を所定量毎に繰出すことができる繰出し装置を提供することを課題とする。【解決手段】粒状物を所定量毎に繰出すものであり、目皿60が回転して下方部材55の繰出し口55aの上方に目皿60の目皿孔61が位置すると目皿60の目皿孔61と下方部材55の繰出し口55aとが連通して目皿60の目皿孔61に溜まった粒状物を下方部材55の繰出し口55aから繰出すように構成される、繰出し装置であって、目皿60の目皿孔61を目皿孔61の軸心方向に伸縮させるようにして目皿60の目皿孔61の容積を増減可能に構成される。【選択図】図3
