Description

The present invention relates to a method of displaying ruled line types (hereinafter referred to as ruled line types) in a word processor.

(Prior Art) Conventionally, in a word processor, there are many cases where tabulation is performed using ruled lines. In this case, it is desirable to prepare a large number of ruled line types, but when a large number of ruled line types are prepared, the print output can be supported, but in the CRT (cathode ray tube) display device, the resolution limit of the display surface Therefore, there is a problem that it is not possible to distinguish and express various types of ruled line types to the extent that they can be identified. There is also a problem that the thickness of ruled lines cannot be read from the CRT display depending on the resolution.

In view of the above points, an object of the present invention is to prepare a large number of ruled line types and make them selectable, and to identify the line types of ruled lines on the CRT screen after tabulation by the selected ruled line types. It is to provide a method of displaying a ruled line type that is displayed as much as possible.

(Means for Solving Problems) In order to achieve such an object, the present invention has a sentence creating function, and the position and line type of a ruled line are set on a text memory and then displayed on a CRT screen. In a word processor configured to display the ruled line font, display codes and line type codes are associated with a plurality of ruled line types including ruled lines that can be printed but cannot be identified on the CRT screen display. It stores a line type table, a display font table that stores display fonts for horizontal and vertical ruled lines with fixed line widths that can be printed out, and that can also be displayed on the CRT screen, and intersection fonts that are displayed at ruled line intersections. Synthesis area memory, writing and reading of data to and from memory, creation of intersection fonts, conversion of data from fonts to display dots, etc. It is equipped with a central processing unit that performs seed processing and control of each part, reads ruled line data consisting of line type code and position of the ruled line set in advance in the text memory, and if the read ruled line is an intersection point, moves vertically and horizontally. The display code corresponding to the ruled line type extending in each direction is obtained from the line type table, and the display code is arranged at the position corresponding to the extending direction of the ruled line to create an intersection point font. While writing in the memory, write the address of the intersection font as ruled line data in the text memory. If the read ruled line is not an intersection, the address of the display font as ruled line data depending on whether it is a horizontal ruled line or a vertical ruled line. Writing to the text memory, and then writing a font from the ruled line data read from the text memory. CRT is converted to the dot data for irradiation Mr. for display
It is characterized by the process of displaying on the screen.

(Example) The present invention will be described in detail below with reference to the drawings. In the present invention, when a ruled line is displayed, as shown in FIG. 1, a ruled line code in which a ruled line type is represented by a line type code at intersections of ruled lines or start and end points of the ruled line (hereinafter collectively referred to as ruled line intersections) The vertical and horizontal ruled lines other than the above are the same as the conventional ones, but the ruled lines are displayed with a certain line width that can be identified on the CRT screen. The internal representation (text content) of the ruled line intersection is represented by a control code (for example, 1C47H) having parameters P1, P2, P3, P4. This parameter has a relationship as shown in the ruled line intersection display font (hereinafter referred to as intersection font) in FIG.
It has a line type code that indicates the type of ruled line that extends in each of the bottom, left, and right directions. Correspondence between the line type code, the display code displayed on the CRT screen, the line type contents, the selected value (the value specified from the keyboard 1), etc. is as shown in FIG. For example, to explain the case of the vertical ruled line in FIG. 2A, at the start point, the thickness is 0.25 points downward (1 point is
0.3514 mm) indicates that a ruled line consisting of a solid line starts, while the end point indicates that a ruled line consisting of a solid line with a thickness of 0.25 points ends in the upward direction. The two fonts in the middle are solid line (fixed thickness) ruled line fonts representing vertical ruled lines. The ruled line in the middle is displayed by the same method as the conventional one.

In the case of (b) in the same figure, a ruled line consisting of a solid line with a thickness of 0.5 points starts at the start point and a thickness of 0.5 points from the left at the end point
Indicates that the ruled line consisting of a solid line of points ends.

If you use such a ruled line font (intersection font),
Regardless of the resolution of the CRT screen (however, a resolution that can distinguish the characters such as display codes A, B, etc. is required), it is possible to code and display the ruled lines of various line types.

As the print output (external expression), for example, a ruled line font as shown in FIG. 4 (here, a case of a 24 × 24 dot font is shown) can be output. This is an intersecting ruled line that extends in four directions in the vertical and horizontal directions with an 8-dot width as shown by the diagonal lines. The 8 × 8 dots indicated by + in the center of the figure are areas where dots are always output, and the 8 × 8 dots at the four corners are areas where no dots are output. The dot width is determined according to the parameter based on the internal representation of the ruled line. At the portions other than the ruled line intersections, the dot width (the number of points) specified at the intersections related to the ruled lines is printed with the same dot width.
For example, in FIG. 2B, the two ruled lines in the middle are printed as solid lines with a thickness of 0.5 points.

Next, a word processor for realizing such a display method will be described. FIG. 6 is a main part configuration diagram showing an embodiment of a word processor for carrying out the display method of the present invention. In the figure, reference numeral 1 denotes a keyboard capable of inputting various commands and character information for creating a document and designating the position and line type of the ruled line.
Reference numeral 2 denotes a central processing unit (hereinafter abbreviated as CPU), which has a function of performing necessary processing and controlling each unit as necessary, and a microprocessor is usually used. Three
Reference numerals 7 to 7 are memories, and more specifically, 3 is a main memory and 4 is a sub memory.

The main memory 3 stores programs necessary for operating as a word processor. The sub memory 4 is
Text memory 5, display font table memory 6,
The line type table memory 7 and the synthesis area memory 8 are included.
Although each memory of the main memory and the sub memory is shown as a separate block configuration in the logical space in the figure, it does not necessarily have to be an individual block in the physical space, and one memory area may be divided and used. It doesn't matter what happens.

Created documents (including ruled lines) in the text memory 5
Data is stored. The display font table 6 stores various CRT display fonts, and also stores a display code font for ruled lines that can be displayed in a distinguishable manner on the CRT screen. The line type table 7 stores a table (corresponding to the selection values, line type codes, and display codes shown in FIG. 5) indicating the correspondence between various line types of ruled lines and codes. The synthesis area 8 is a memory in which the display code at each intersection of ruled lines is stored.

A CRT display device 9 receives display data (characters, ruled lines, and other display output) given from the CPU 2, and displays it on the CRT screen in dots. A printing device 10 prints out a created document (including ruled lines and other symbols and signs) by designating.

The operation in such a configuration will be described below. Although the text is created by the same method as the conventional method, the description thereof is omitted here because it is not directly related to the method of the present invention, and only the operation related to the ruled line will be described. First, in the ruled line setting mode, the line type (the line type code is specified by the selection value shown in FIG. 5) and the position of the ruled line (start point, direction, and length are sequentially specified) are specified. The set ruled line data is stored in the address of the text memory 5. At this point, the ruled lines are not displayed, and the display on the CRT screen is executed only after the ruled line setting is completely completed. This process is performed under the control of the CPU 2, and its procedure will be described below with reference to the flowchart of FIG.

1) Read the text contents of the address associated with the ruled line from the text memory 5.

2) It is determined whether or not the read ruled line is an intersection. If it is an intersection, proceed to item 3). If it is not an intersection, proceed to item 6).

3) A display code (for example, A) corresponding to the line type in the left direction is brought from the display font table 8.

4) The display code (A) is written to the leftward position in the composition area of the composition area memory 8 (see FIG. 7B).

5) In the following, for each of the upper, lower, and right directions, the line type is written in the compositing area by the same procedure as in the above 3) to 4), and the intersection font composed in this way (see FIG. )) 'S address is passed to text 5 (written in text). After that, the operation shifts to 7) which will be described later.

6) If the read content is a ruled line that does not intersect, check whether it is a horizontal ruled line or a vertical ruled line. For a horizontal ruled line, the address of the horizontal ruled line font in the display font table 6 is passed to the text, and for a vertical ruled line, the address of the vertical ruled line font is similarly passed to the text. After that, the process proceeds to the next 7) display operation.

6) When the above processes for all ruled lines are completed, the display operation is started. CPU2 reads the contents of text memory 5
Display on CRT9. In this case, the character code or ruled line code stored in the text is referred to the intersection font of the display font table and the composition area, converted into display dot data, and passed to the CRT display device 9.

The above operation is performed for each ruled line. As a result, for example, a screen display as shown in FIG. 1 is obtained, and the ruled line of the line type that was originally indistinguishable on the CRT screen can be displayed in an identifiable manner by the display method of the present invention.

In addition, although the ruled line of the solid line is described in the embodiment, the case of the chain line can be realized in the same manner as above. The operation will be omitted because it is obvious without need to explain it sequentially.

If you want to output in the same font as the display, such as test printing, which is used to check the print output, you can use the displayed font for print output to perform ruled line type printing. is there.

Further, in the embodiment, the description has been made with the font of 24 × 24 dots, but the number of dots constituting the font is not limited to this.
For example, a 32 × 32 dot configuration may be used, in which case an intersection font that is easier to identify can be displayed.

(Effects of the Invention) As described above, the present invention has the following effects.

Conventionally, only one type of ruled line could be displayed due to the resolution limitation of the CRT, but a large number (eg, 14 types) of ruled line types can be arbitrarily selected and displayed, and a line of various line types can be created on the CRT screen. Tables are possible.

Since the ruled line type is managed by a table associated with the selected value, the line type code (parameter value), and the display code, the correspondence can be arbitrarily changed and set as necessary.

After tabulation by a large number of ruled line types, the line types of ruled lines extending in four directions are displayed at the intersections, start points, and end points on the screen, so that a large number of ruled line types can be easily identified.
