PROBLEM TO BE SOLVED: To provide a control device for a farm work machine capable of reducing device costs of a farm work machine and a control device corresponding to the farm work machine and including an individual unit and a common unit having high versatility.SOLUTION: The control device for a farm work machine includes: a common unit 110 including common control means CPU71 comprising elements common to plural control means controlling plural farm work machines respectively, a display section 74 for displaying display information on the farm work machine, and a communication section 72 and an individual unit 111 including farm work machine unique control means CPU81 for controlling a unique control target included in the farm work machine connected to a travel vehicle and a communication section 82. The communication section 72 and the communication section 82 can communicate with each other. The individual unit 111 includes a work machine communication section 84 for transmitting/receiving a signal between the work machine communication section and the farm work machine via a signal line connected with a farm work machine connector section, thereby the common unit 110 can be configured by hardware having high versatility and device costs can be reduced.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2017,JPO&INPIT【課題】農作業機とその農作業機に対応した農作業機用制御装置とを合わせた装置コストを低減でき、個別部と、汎用性の高い共通部とを備えた農作業機用制御装置を提供する。【解決手段】農作業機用制御装置は、複数の農作業機を各々制御する複数の制御手段に共通する要素からなる共通制御手段(CPU71)、農作業機に関する表示情報を表示する表示部74、及び通信部72を有する共通部110と、走行車に接続した農作業機が有する固有の制御対象を制御するための農作業機固有制御手段(CPU81)、及び通信部82を有する個別部111と、を備える。通信部72と通信部82は通信可能に構成されている。個別部111が、農作業機コネクタ部に接続される信号線を介して農作業機との間で信号を通信する作業機用通信部84を備えるので、共通部110を汎用性の高いハードウェアで構成することができ、装置コストを低減することができる。【選択図】図4
