The present invention suitably erases wheel tracks. The present invention is provided with a device body (11) that can be linked to the rear side of a work vehicle. The device body (11) is provided with pairs of left and right earth collectors (12) that are disposed in a diagonal orientation so as to approach each other in the left-right direction of the work vehicle toward the rear side thereof. Defining one pair of left and right earth collectors (12) as one earth collector pair, a plurality of earth collector pairs (12a–12c) are provided in a state wherein a plurality of the earth collectors (12) on the left side are arranged with a gap therebetween in the left-right direction of the work vehicle and a plurality of the earth collectors (12) on the right side are disposed with a gap therebetween in the left-right direction of the work vehicle. The plurality of earth collector pairs (12a–12c) are configured so as to have different lengths in the front-back direction of the work vehicle.
This region registration system is provided with a positioning antenna, a position acquisition unit, a reference-point specification unit, a direction specification unit, a candidate-point registration unit, and a region registration unit, and acquires an antenna position as a measurement point. The reference-point specification unit specifies a corner antenna reference point. The direction specification unit specifies a turning direction of a rice seedling transplanter (1) that has passed the corner antenna reference point. The candidate-point registration unit biases the corner antenna reference point to a position forward of the rice seedling transplanter (1) at the time of measuring said corner antenna reference point, and at the same time, registers, as a corner candidate point, a position biased toward either side in the width direction of said rice seedling transplanter (1) in accordance with the turning direction specified by the direction specification unit. The region registration unit is capable of registering a region that encompasses a corner candidate point.
A control terminal 3 includes: a storage unit 94 for storing, in association with identification information of an apparatus 2, app use permitted/prohibited information that indicates whether the use of each of a plurality of applications by the apparatus 2 is permitted or prohibited; and an app use control unit 84 that receives the apparatus 2 identification information from the apparatus each time wireless communication connection with the apparatus 2 begins, and that controls the use of the plurality of applications on the basis of the app use permitted/prohibited information that is stored in the storage unit 94 in association with the received identification information.
