PROBLEM TO BE SOLVED: To provide a seedling transplanter, photographing the magnitude of farms unevenness and seedlings planted posture by a photographic device and automatically stabilizing the vertical movement of its seedling planting apparatus and seedlings planted posture in accordance with images thus photographed.SOLUTION: The seedling transplanter is such that: a seedling planting apparatus 8 is installed on the rear side of its traveling vehicle 14 with front wheels 10 and rear wheels 12 wherein the seedling planting apparatus 8 includes: a seedling tank 6 feeding seedlings to a seedling-receiving guide 5 provided with a seedling-receiving port 4 a center float 1 and a side float 2 laid under the seedling tank 6 and sliding on farms surface and a planting mechanism 7 planting seedlings through making the seedling-receiving port 4 descend. In this seedling transplanter, a photographic device 17 photographing an image representing farm surfaces unevenness is provided and laid above the seedling planting apparatus 8, the magnitude of farm surfaces unevenness is determined based on the image photographed by the photographic device 17, and a control is constituted such that: when there are plenty of such unevenness, the lift control sensitivity of a lift cylinder 15 making a lift link 16 ascend/descend is lowered, while when there are slight such unevenness, sensitivity of the lift cylinder 15 is raised.COPYRIGHT: (C)2013,JPO&INPIT【課題】圃場の凹凸の多少、及び苗の植付姿勢を撮影装置で撮影し、撮影された画像に合わせて苗植装置の昇降、及び植付姿勢の安定化を自動的に図る苗移植機を提供する。【解決手段】苗取口4を形成した苗受ガイド5に送る苗タンク6と、苗タンク6の下部に設ける圃場面を滑走するセンタフロート1とサイドフロート2と、苗取口4を下降して苗を植え付ける植付装置7を設けて苗植装置8を構成し、苗植装置8を前輪10及び後輪12を備えた走行車体14の後側に装着した苗移植機において、苗植装置8の上方位置に圃場面の凹凸を表わす画像を撮影する撮影装置17を設け、撮影装置17が撮影した画像で圃場面の凹凸の多少を判別し、圃場面の凹凸が多いときは昇降リンク16を昇降させる昇降シリンダ15の昇降制御感度を低下し、圃場面の凹凸が少ないときは昇降シリンダ15の昇降制御感度を上げる制御構成とする。【選択図】 図4
