PROBLEM TO BE SOLVED: To provide a seeding device in which dropout of seeds to the outside of the device is suppressed even when holding of the seeds is unnecessarily released.SOLUTION: When a seed storage 2 turns to the left, a peripheral wall penetrating hole 21 and a holding section 22 holding the seeds rotate and move in an anticlockwise direction. When the holding section 22 releases the holding of the seeds in a state that the peripheral wall penetrating hole 21 is positioned at the lowermost position of the seed storage 2, the seeds released from the holding section 22 drop to the left of a partitioning wall 25, pass through the peripheral wall penetrating hole 21, and are seeded on a medium member B. When the holding of the seeds in the holding section 22 is unnecessarily released, the seeds dropped out of the holding section 22 drop to the right or left of the partitioning wall 25. The seeds dropped to the right of the partition wall 25 are separated from the peripheral wall penetrating hole 21 by the partition wall 25, consequently there is no possibility of their dropping to the outside of the device. The seeds dropped to the left of the partition wall 25 pass through the peripheral wall penetrating hole 21 and are seeded to the medium member B, consequently there is no possibility of their dropping to the outside of the device.COPYRIGHT: (C)2014,JPO&INPIT【課題】種子の保持が無用に解除されたとしても、装置外部への種子の脱落を抑制することができる播種装置を提供する。【解決手段】種子収容体2が左回転すると、周壁貫通孔21と種子を保持した保持部22とが反時計回りに回転移動し、周壁貫通孔21が種子収容体2の最下部に位置している場合に保持部22が種子の保持を解除すれば、保持部22から解放された種子が区画壁25の左側へ落下し、周壁貫通孔21を通り抜けて培地部材Bに播かれる。保持部22における種子の保持が無用に解除された場合、保持部22から脱落した種子は、区画壁25の右側又は左側へ落下する。区画壁25の右側へ落下した種子は、区画壁25によって周壁貫通孔21から隔てられるため、装置外部へ脱落する虞はない。区画壁25の左側へ落下した種子は、周壁貫通孔21を通り抜けて培地部材Bに播かれるため、装置外部へ脱落する虞はない。【選択図】図7
