PROBLEM TO BE SOLVED: To allow a worker to confirm what working speed is necessary to drive a pest control machine in order to enable the control of the spraying amount under appropriate spraying conditions before the work at a working site when a suitable range for spraying conditions can be simply recognized, especially when a target spraying amount per unit area is set.SOLUTION: A device for controlling the spraying amount of a pest control machine includes control means 10 for controlling the spraying amount to correspond to a target spraying condition which is a detected spraying condition set and input. The control means 10 includes display input means 11 which displays the adjustable range of the target spraying condition and enables setting and inputting in the adjustable range, wherein a plurality of the target spraying conditions can be set and input one by one, and the adjustable range of the target spraying condition enabling the later input based on the previously set and input target spraying condition is determined.COPYRIGHT: (C)2011,JPO&INPIT【課題】現場での作業前に、簡単に散布条件の適正範囲が確認でき、特に、単位面積当たりの目標散布量を設定した場合に、どれ位の作業速度で防除機を走らせれば適正な散布条件での散布量制御が可能であるかを作業者が把握できるようにする。【解決手段】検出された散布条件が設定入力された目標散布条件になるように散布量を制御する制御手段10を備え、制御手段10は、目標散布条件の調整可能範囲を表示して調整可能範囲内での設定入力を可能にする表示入力手段11を備え、複数の目標散布条件を一つずつ設定入力可能にすると共に、先に設定入力された目標散布条件に基づいて後に設定入力可能にする目標散布条件の調整可能範囲を決定する。【選択図】図1
