PROBLEM TO BE SOLVED: To provide a rice transplanter capable of compactly assembling an actuator or the like which induces the movement of streak markers from working posture to storage posture at low cost.SOLUTION: The rice transplanter includes the right and left streak markers 72 for forming the planting track for the subsequent step in a field surface, the actuator 79 for raising the streak markers 72 from the field surface to the ground, and a marker lifting body 78 which is activated by the actuator 79, and is configured in a manner so as to allow the movement of the streak markers 72 to the working posture in which the streak markers are landed on the field surface, or to the storage posture in which the streak markers are lifted from the field surface to the ground. The rice transplanter has a structure provided with a marker rotation fulcrum shaft 74 which supports the streak markers 72 in a manner so as to allow the movement thereof to the working posture or the storage posture, wherein the marker lifting body 78 is mounted on the marker rotation fulcrum shaft 74.COPYRIGHT: (C)2010,JPO&INPIT【課題】作業姿勢から収納姿勢に筋引きマーカを移動させるアクチュエータ等を、低コストでコンパクトに組付けることができるようにした田植機を提供する。【解決手段】圃場面に次工程の植付け軌跡を形成する左右の筋引きマーカ72と、筋引きマーカ72を圃場の圃場面から地上に上昇させるアクチュエータ79と、アクチュエータ79によって作動させるマーカ昇降体78を備え、前記筋引きマーカ72を、圃場面に着地させた作業姿勢、または圃場面から地上に持上げた収納姿勢に移動可能に構成した田植機において、前記作業姿勢又は前記収納姿勢に筋引きマーカ72を移動可能に支持するマーカ回動支点軸74を備える構造であって、マーカ回動支点軸74上に前記マーカ昇降体78を配置した。【選択図】図7
