JP, 2013-128466, A

  In the ordinary type combine, the driver could check visually in a part of the reaping condition of the reaper, but it was difficult to confirm the reaping condition of the entire cutting width. Therefore, if the driver can visually recognize the rear condition of the machine body, it is possible to confirm the condition of the cutting mark by the mowing section, the condition of the discharge discharged from the threshing device, and the like. In other words, it is possible to determine whether or not leftovers or the like are generated from the condition of the cut by the reaper and to determine whether soil, pebbles, etc. are mixed in the scraps from the condition of the discharged matter. be able to.

  To add the explanation, for example, if the part to be inspected and repaired can not be properly installed at the time of maintenance work, there is a possibility that the defective part does not operate well and the reaping work can not be performed well. If the setting of the speed balance between the machine traveling speed and the reaping speed by the reaper is inappropriate, the reaping work can not be performed well within the cutting width range, and all or part of the planted grain remnants are left uncut in the field May occur. If the setting mowing height for the planted rice weir by the mowing part is too low, the mowing device may cut off the weir scene and soil, pebbles, etc. may be mixed in the weeding weir.

  If the driver can check the situation behind the machine while continuing the driving operation in the driving unit, it is possible to immediately determine the above-mentioned inappropriate working state. However, in the above-described conventional configuration, it is difficult for a driver who performs a driving operation in the driving unit to visually recognize the situation behind the vehicle. If the driving unit is provided with a cabin, it is particularly difficult to check the condition behind the vehicle.

  Therefore, it is conceivable to provide an imaging device (camera) for imaging the rear of the machine body and to confirm the situation behind the body with an image or the like photographed by the imaging device. In that case, it is desirable to be able to appropriately capture the situation behind the aircraft.
