PROBLEM TO BE SOLVED: To provide a seeding type implement capable of securing easiness of entering/exiting a field and performing automatic travel control, and an automatic travel control system thereof.SOLUTION: A seeding type implement comprises: a satellite positioning unit capable of detecting a position of a travel machine body C by using a navigation satellite； a work unit capable of performing seeding work of seedlings to a field； a route setting part capable of setting a target travel route LM on which the travel machine body C performs the seeding work and travels, on the basis of a field shape； and an automatic travel control part capable of performing an automatic travel control for controlling the travel machine body C to travel along the target travel route LM on the basis of a position of the travel machine body C. The route setting part can set the target travel route LM on the inside of the field relative to a circling travel route on which the work unit performs seeding work over a work width of the work unit and the travel machine body C goes around the field.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2020,JPO&INPIT【課題】圃場を出入りの容易性が確保されつつ自動走行制御が可能な植播系作業機及び植播系作業機の自動走行制御システムの提供。【解決手段】航法衛星を用いて走行機体Ｃの位置を検出可能な衛星測位ユニットと、圃場に対する種苗の植播作業が可能な作業装置と、走行機体Ｃが植播作業を行いつつ走行する目標走行経路ＬＭを圃場形状に基づいて設定可能な経路設定部と、走行機体Ｃの位置に基づいて、目標走行経路ＬＭに沿って走行機体Ｃが走行するように制御する自動走行制御が可能な自動走行制御部と、が備えられている。経路設定部は、作業装置の作業幅に亘って作業装置が植播作業を行いつつ走行機体Ｃが圃場を周回走行する周回走行経路よりも圃場内側に目標走行経路ＬＭを設定可能に構成されている。【選択図】図６
