しかして、前記サイドカメラ２０のうち、脱穀装置２の供給穀稈搬送装置１２を設けた側のサイドカメラ２０は、供給穀稈搬送装置１２の穀稈搬送通路よりも上方に設ける。
実施例では、前記支持部材２８を上部カバー１３に固定し、支持部材２８にサイドカメラ２０を取付ける。
サイドカメラ２０が搬送穀稈より上方に位置することで、被写体部分が搬送穀稈の影とならず光が当たり映像が鮮明となる。また、脱穀装置２の後方の排藁処理部１６の排藁搬送部の監視や、刈取部３の左前方部の左分草穀稈の条合せの状態を視認するに当たり、搬送穀稈の上方から搬送穀稈を映像で捉えることで視認範囲が拡大する。
図８は図１におけるＡ位置のサイドカメラ２０の映像のイメージを、図９は図１におけるＢ位置のサイドカメラ２０の映像のイメージを、夫々表現したものである。 Thus, the side camera 20 on the side of the side camera 20 on which the supply cereal transport device 12 of the threshing apparatus 2 is provided is provided above the cereal transport path of the supply cereal transport device 12.
In the embodiment, the support member 28 is fixed to the upper cover 13, and the side camera 20 is attached to the support member 28.
Since the side camera 20 is positioned above the transporting culm, the subject portion does not become a shadow of the transporting culm and the light hits and the image becomes clear. In addition, when monitoring the waste transporting unit of the waste processing unit 16 behind the threshing device 2 and visually confirming the state of the left weed cereal mashing in the left front part of the cutting unit 3, The viewing range is expanded by capturing the transported cereals from the image.
8 represents an image of the video of the side camera 20 at the position A in FIG. 1, and FIG. 9 represents an image of the video of the side camera 20 at the position B in FIG.

しかして、サイドカメラ２０は上方回動して扱胴周辺を開放する上部カバー１３に取付けられているので、上部カバー１３をオープンさせると、サイドカメラ２０も上部カバー１３と共に上方移動し、脱穀装置２のメンテナンス作業の障害とならず、メンテナンス作業を容易にする（図１０）。 Since the side camera 20 is attached to the upper cover 13 that pivots upward to open the periphery of the handling cylinder, when the upper cover 13 is opened, the side camera 20 also moves upward together with the upper cover 13 and the threshing device The maintenance work is not an obstacle to the maintenance work 2 and facilitates the maintenance work (FIG. 10).

しかして、刈取部３から脱穀装置２の側部にはナローガイド３６を設け（図１１）、左側のサイドカメラ２０はナローガイド３６の分草状態を映し出すように構成し、前記サイドカメラ２０は刈取クラッチ（図示省略）の「入り」に起因して、前記映像を映し出す。
そのため、ナローガイド３６の分草状況が確認でき、ナローガイド３６を最適な張出位置に調整できる。 Therefore, a narrow guide 36 is provided on the side of the threshing device 2 from the reaping unit 3 (FIG. 11), and the left side camera 20 is configured to project the weeding state of the narrow guide 36, and the side camera 20 The image is displayed due to the “engagement” of a mowing clutch (not shown).
Therefore, the weeding condition of the narrow guide 36 can be confirmed, and the narrow guide 36 can be adjusted to the optimum overhang position.

しかして、左右のサイドカメラ２０は、左右一対のクローラ４０により構成した走行装置１の前後の重心位置に相当する部分が撮影範囲となるように配置する。
「アユミ」と呼ばれる補助具４１を用いたトラック４２の荷台への積み込みや、積み降ろし（図１２、図１３）、また、畦越えに際して、クローラ４０の重心位置が通過するときにシーソーのように前側が下がるが、サイドカメラ２０による走行装置１の前後重心位置の映像により、適正な速度操作等を行え、操作性を向上させ、走行安全性を向上させる。

In addition, when the cutting work is performed at the heel 43 or when the width is reduced, the side of the aircraft is photographed by the side camera 20 and visually recognized by the operator, thereby improving operability and driving safety.

この場合、サイドカメラ２０は、操縦部１０に設けたパワステレバー（図示省略）の操作をパワステレバー操作感知手段４４が感知すると、前記走行装置１の前後の重心位置に相当する部分を撮影し、モニタ２７に映し出すように出力するように構成する（図１５）。
パワステレバーは、機体の旋回操作に使用し、機体が旋回すると、旋回の抵抗により走行装置１に泥土が寄ったり、また、機体が沈下したりするが、これらの旋回状態をサイドカメラ２０により撮影して視認することにより、的確な操作が容易に行え、操作性を向上させる。 In this case, when the power steering lever operation sensing means 44 senses an operation of a power steering lever (not shown) provided in the control unit 10, the side camera 20 takes a portion corresponding to the center of gravity position before and after the traveling device 1, It is configured to output so as to be projected on the monitor 27 (FIG. 15).
The power steering lever is used for the turning operation of the aircraft. When the aircraft turns, mud soil approaches the traveling device 1 due to the turning resistance, and the aircraft sinks. By visually recognizing it, an accurate operation can be easily performed and the operability is improved.
