PROBLEM TO BE SOLVED: To prevent interference between a reaping conveyance grain culm and a planting grain culm, and thereby perform conveyance of the reaped grain culm smoothly.SOLUTION: A combine includes a narrow guide (15) being openable over between a grass division operative position for guiding grass division of a planting grain culm in an unmown field side to the outside of the reaping width of the reaping unit (3) and a storage position stored in a machine body side. In an opening/closing operation mechanism (16) for performing opening/closing operation of the narrow guide (15), first imaging means (21) for photographing a situation of the planting grain culm in the unmown field side and second imaging means (22) for photographing a conveyance situation of the reaped grain culm are installed, and an image processing unit for controlling a position of the narrow guide by verifying an image from the first imaging means (21) and the second imaging means (22) is provided.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2020,JPO&INPIT【課題】刈取搬送穀稈と植立穀稈との干渉を防止し、刈取穀稈の搬送を円滑に行えるものとする。【解決手段】未刈地側の植立穀稈を刈取部（３）の刈幅の外側に分草案内する分草作用位置と機体側に収納された収納位置とにわたって開閉可能なナローガイド（１５）を備えたコンバインにおいて、ナローガイド（１５）を開閉作動させる開閉作動機構（１６）には、未刈地側の植立穀稈の状況を撮影する第１撮像手段（２１）と刈取穀稈の搬送状況を撮影する第２撮像手段（２２）を設置し、第１撮像手段（２１）および第２撮像手段（２２）からの画像を照合してナローガイドの位置を制御する画像処理部を設けてある。【選択図】図３
