D. Problems to be Solved by the Invention However, in the drawing display data creation method described above, for example, in order to display a figure that matches one line segment connected to six characters, it is necessary to give instructions six times for each character. Therefore, it takes time to create shapes.

Additionally, in the past, there was only one type of line thickness, but in recent years, large-capacity drawing display devices have been used, and thick lines have been used. Central line. Three types of thin lines are now required, and in the example shown in Figure 5, the line connecting G and DE of the power generation equipment is normally displayed as a thick line, the horizontal line shown in Figure 6 is displayed as a thick line, and the rectangle is also displayed as a medium line. You may want to show it with a line. Therefore, the character data of the middle line corresponding to each character data of 21 to DD shown in FIG. do. For example, the above 4
The median line data of the horizontal line pattern stored first is 7.
It is stored in the first place, and the thick line data is stored in the Atth place. Figure 8 is an explanatory diagram showing the correspondence between them. Each square in the diagram indicates the minimum unit of light emitted on the display screen, and the thin line is the thickness of one square as shown in Figure (a). The line is shown in the figure (b
) as shown in Figure (c), the thick line is the thickness of 3 squares as shown in Figure (c), and the thickness can be distinguished by emitting light, but it takes more time to select them. It also ended up costing me a lot of money.

Furthermore, although this CRT screen data can be stored in the input/output device, there is a drawback in that it cannot be processed and used for customer approval drawings, etc.

The present invention was created in view of these problems, and
The characters and data used in large-capacity drawing display devices for industrial plant monitoring and instrumentation systems can be created with line thickness taken into account, and the created data can be used as drawings for customer approval on pen plotters and It is an object of the present invention to provide a drawing display data creation device that can also output to an electrostatic block.
