PURPOSE:To check the interference of working information on a display easily, by superposing plural working information individually in different colors and displaying on a color graphic display, and checking the mixed color. CONSTITUTION:Setting information 101 from a keyboard 11 and plural working information 100 are converted into color information 102R, 102B, and 102G by color memories 10R, 10B, and 10G and inputted to a color composition detecting circuit 14 through parallel/series converting circuits 12R, 12B, and 12G. On the other hands, display signals 104 are displayed in different colors on the color graphic display 16. A mixed color is formed by interfering and superposing plural working information 100 and displayed on the color graphic display 16. In addition, the color composition detecting circuit 14 outputs a mixed color signal 108 to supply the signal 108 to an alarm generating circuit 20 and an alarm is generated by an alarm signal 110. Thus, the operator can check the interference of the working information. |
