PROBLEM TO BE SOLVED: To solve the problems that the whole device of a seeder becomes larde, expensive and difficult to be handled, and that maintenance thereof requires much labor.SOLUTION: A seeder is constituted as follows. A seeding head part is moved freely in the X-axis and Y-axis directions, and after positioning by numerical control by allowing the position of a seed discharge port to agree with the position of a seeding hole on a seeding bed, a fine vibration is imparted to the head part as long as a prescribed time, to thereby conduct seeding operation by dropping seeds one by one.COPYRIGHT: (C)2015,JPO&INPIT【課題】 播種機の装置全体が大型化して高価となるとともに操作が扱い辛く、メンテナンスも手数がかかるという問題点がある。【解決手段】 種子を蒔くヘッド部をX軸及びY軸方向へ自在に移動させ、種子排出口の位置を播種床の播種孔の位置に合わせて数値制御で位置決めした後に、所定の時間だけヘッド部に微振動を与え種子を一粒ずつ落下させて播種するように構成する。【選択図】図1
