Abstract
A machine control device includes a control unit body and a display operation device that can be separated from the control unit body. The display operation device uses a mechanism which does not use power while the display operation device waits for charging. The display operation device is automatically turned on and off on the basis of the on and off states of the control unit body. A power switch can be provided only in the control unit body. The supply of power from the control device can be automatically turned on and off on the basis of the state of the display operation device. Therefore, the operability and reliability of the machine control device are improved.
