Claims

[Scope of Claim for Utility Model Registration] Sensor arms are rotatably installed in the divider part at the front of the fuselage, protruding from both left and right sides of the divider part, and the sensor arms rotate based on contact with grain culms. In a harvesting machine that performs automatic direction control, both of the sensor arms are configured to be able to rotate independently, and a left and right switch that can be switched from a normal state to an operating state by rotation of each sensor arm is provided, and furthermore, the sensor arms are configured to be able to rotate independently. Two AND circuits are provided which receive signals from the left and right switches respectively and output them to the left and right turning means, and these AND circuits each receive signals from the other switch of the left and right switches in the operating state. When either the left or right switch is activated, one of the AND circuits is output, and when both the left and right switches are activated, neither of the AND circuits is output. An automatic direction control device characterized in that it is configured as follows.
