PROBLEM TO BE SOLVED: To reduce the size of a control panel by displaying warnings and abnormal condition notices on a display section. SOLUTION: The device is provided with a display means 7 which displays icons to indicate warnings or abnormal condition notices. When warning conditions or abnormal notice conditions are continuously generated, the means 7 displays icons, that indicate each condition, successively while shifting them so that the icon, which indicates the latest condition, is displayed at the same position. Since the icon, which indicates the latest condition, is displayed at the same position, an operator easily comprehends the latest display among plural displays by discriminating the position. |
