<p>PROBLEM TO BE SOLVED: To turn off the power source of a display part while turning on a power source on the device body by controlling the supply of power to a display means based on an instruction for turning on/off the power source so as to stop/start the supply of power independently of the supply of power to an information processing means. SOLUTION: A power source 1107 has an analog output power source 5V, digital control power source 12V and LCD power source 12V. An LCD power source SW processing part 1108 receives a signal from a switch, sends the signal to the power source 1107 and cuts off the supply of power to the LCD power source. A control panel has no independent power source and receives the supply of power from a control box 103. In this case, by dividing the power source inside the control box 103 and processing an instruction signal corresponding to the on/off operation of a back light power source switch through the power source switch processing part 1108, only the display of a screen is turned off. Therefore, the supply of power to the display part to receive the supply of power from the device body can be stopped/started independently of the device body.</p> |
