  • Sensor for use in controlling operation of mobile farming machine
    Patent number: 4211921
    Abstract: A sensor for use in controlling the operation of a mobile farming machine which has an image taking means carried by the machine and adapted to take the image of a part of the field to be worked, and photoelectric converting means adapted to convert the image into electric signal. The photoelectric converting means consist of a plurality of photoelectric elements disposed in a row crossing the line of movement of the machine, so that the states of the photoelectric elements are changed as the position of a boundary involved by the image taken by the image taking means is moved. Thus, the deviation of the machine from the correct course is detected through the change of states of the photoelectric elements.
