用新案登録請求の範囲第１項記載の移動収穫機に
おける自動方向制御装置。[Claims for Utility Model Registration] (1) Based on the detection signal of the direction sensor provided in the reaping unit when approaching the grain culm and the detection signal when separating from the grain culm, the drive device is operated as appropriate to automatically change the direction of the traveling machine. In the mobile harvester configured to correct the grain culm, the detection signal from the direction sensor when the grain culm approaches is divided into a signal of a predetermined time or less and a signal of a predetermined time or more, and the signal of the predetermined time or less is a signal of the drive. An automatic direction control device for a mobile harvester, characterized in that the automatic direction control device for a mobile harvester is configured to be ignored in the direction correction operation of the device, and to perform the direction correction operation of the drive device in response to a signal that lasts longer than the predetermined time. (2) The automatic direction control device for a mobile harvester according to claim 1, wherein the predetermined time is set short when the traveling machine is running at high speed and set long when the traveling machine is running at low speed.
