PROBLEM TO BE SOLVED: To prevent power of a capacitor from being reduced after automatic stop of an engine in a construction machine having an auto stop function.SOLUTION: A control device of a construction machine comprises: an engine control part 5 which performs auto-stop control for making an engine 1 stop automatically when a preset auto-stop condition is established; a capacitor 6 which serves as a power source for electric and electronic equipment including the engine control part 5; a power source control part 7 which controls supply/cutoff of power from the capacitor 6 to the electric and electronic equipment. The power source control part 7 is constituted so as to perform power source cutoff control for stopping the power supply from the capacitor 6 to the electric and electronic equipment after the engine 1 is automatically stopped by the auto-stop control. |
