[Industrial applications]

The present invention relates to an improvement of a document editing device having a ruled line output function.

[Conventional technology]

2. Description of the Related Art In a document editing apparatus capable of creating tables and figures in a document, a ruled line type is coded and recorded in order to record a ruled line.

[Problems to be solved by the invention]

However, since different codes are assigned to vertical lines / horizontal lines / intersections, when the number of types of ruled lines increases, the number of codes required to represent the ruled lines increases endlessly, and the storage capacity required to store the codes increases. To increase. However, since the storage capacity for storing codes is limited, the types of ruled lines cannot actually be increased to a certain degree or more, and the expressive power is poor.

The present invention has been made in view of this point,
An object of the present invention is to provide a document editing apparatus capable of increasing the number of types of ruled lines that can be output without increasing the number of codes required for storing ruled lines.

[Means for solving the problem]

The present invention provides many types of ruled lines by performing code conversion in a situation where a ruled line storage code for recording ruled lines in a document recording unit can express only a narrower range than the type of ruled line to be output. Can be output.

First, a ruled line output code is assigned to all the ruled lines to be output. This is realized by selecting n ruled lines to be used at the same time and converting the ruled line storing code into a ruled line output code according to what ruled line storing code corresponds to which ruled line at the time of output by providing n means (n is a natural number).

FIG. 1 is a diagram illustrating the principle of the present invention. In the figure,
1-1 to 1-n are code conversion units, 2 is a switching unit, 3 is a document editing unit, 4 is an output unit, and 5 is a document recording unit.

Each of the code conversion units 1-1 to 1-n converts a ruled line storage code into a ruled line output code. As a conversion method, there is a method using a result of performing an operation on the ruled line recording code or a method using a code conversion table. The ruled line recording code is a code indicating the number of the ruled line in the currently output ruled line pattern to be output. The ruled line output code indicates which one of a plurality of ruled line patterns is to be output.
Although not shown, it goes without saying that there is a pattern memory having a plurality of ruled line patterns stored in one-to-one correspondence with ruled line output codes. This pattern memory may be present in the switching unit 2 or in the output unit 4.

The switching unit 2 switches between the code conversion units 1-1 to 1-n according to an instruction from the document editing unit 3. The switching unit 2 sends the ruled line storage code sent from the document editing unit 3 to the designated code conversion unit 1-i (i is 1, 2,..., N).
This is a part for obtaining a ruled line output code and sending it to the output unit 4 or the like.

The document editing unit 3 performs processing such as notifying the switching unit 2 of the code conversion unit 1-i to be used according to an instruction input from the operator, editing the document, and storing the document in the document recording unit 5.

The document recording unit 5 records the document edited by the document editing unit 3, and uses a ruled line storage code to record a ruled line. Of course, it is also possible to assign a character code to one ruled line storage code in a one-to-one correspondence and to record in the form of a character code.

[Action]

It is assumed that the code conversion unit 1-1 has been selected by the operator. When the ruled line storage code is sent from the document editing unit 3 in this state, the switching unit 2 sends the ruled line storage code to the code conversion unit 1-1. The code conversion unit 1-1 obtains a ruled line output code corresponding to the transmitted ruled line storage code, and sends the obtained ruled line output code back to the switching unit 2. The switching unit 2 sends the ruled line output code (or a spiral pattern corresponding to the output code) sent from the code conversion unit 1-1 to the output unit 4, and the output unit 4 sends the ruled line output code to the ruled line output code. The corresponding ruled line pattern is output.

〔Example〕

FIG. 2 is a diagram showing an example of a hardware configuration of the document editing apparatus. In the figure, 10 is a central processing unit, 11 is a main memory, 12 is a hard disk, 13 is a CRT display, 14
Indicates a printer.

The output unit 4 in FIG. 1 corresponds to the CRT display, 13 or the printer 14 in FIG. Also, the code conversion units 1-1 to 1-n, the switching unit 2, and the document editing unit 3 in FIG. 1 are functionally present in a portion composed of the central processing unit 10 and the main memory 11 in FIG. It is. The document recording section 5 shown in FIG. 1 exists in the hard disk 14 shown in FIG.

FIG. 3 is a diagram showing examples of ruled line output codes and ruled line patterns. In the above description, it is assumed that the ruled line storage code is 00 to 11 (binary number) and the ruled line output code is 000 to 111 (binary number). FIG. 3 shows an example of a ruled line pattern corresponding to eight ruled line output codes 000, 001,..., 111. in this case,
Since there are only four ruled line storage codes for eight ruled line types, the display code cannot be used as it is as a ruled line storage code. Therefore, code conversion is required.

FIG. 4 is a diagram illustrating a code conversion table. In the figure, T1 and T2 indicate code conversion tables.

It is assumed that the code conversion unit in FIG. 1 performs code conversion using the code conversion table. The code conversion tables T1, T2, etc. exist in the main memory 11. In order to convert the input ruled line storage code a into a ruled line output code, the contents of the address indicated by the value obtained by adding a to the address ADR1 of the code conversion table T1 may be used as the ruled line output code. In the example shown, the ruled line output code is 100
(Binary number). A plurality of code conversion tables can be provided, in which case ADR2, ADR3,. Switching unit 2
Selects one of a plurality of code conversion tables.

FIG. 5 is a diagram for explaining creation of a code conversion table. The code conversion table may be prepared in advance or may be prepared by an operator. Hereinafter, the procedure when the operator creates the information will be described.

When the operator selects the code conversion table creation process, the fifth
A screen as shown in FIG. In order to have a plurality of code conversion tables, numbers are given to the code conversion tables. In the illustrated example, it is assumed that 1 has been input as the number of the code conversion table.

When the code conversion table number is input, a screen like the one shown in b is displayed. Enter the number of the ruled line to be used on the screen in b. In the illustrated example, it is assumed that 1 has been input as the ruled line number.

When the ruled line number is input, a screen like C is displayed. In C, a ruled line code is input. In the illustrated example, it is assumed that 1 has been input as the ruled line code.

When the ruled line code is input, a screen like the one shown in FIG. As shown by d, 1 corresponds to the first ruled line code.
The numbered line is displayed.

Hereinafter, when a ruled line output code is assigned to the ruled line storage codes 2 to 4 in the same manner, a screen like E is displayed.

The code conversion table T1 can be created by the procedure as described above. Hereinafter, a code conversion table as shown in FIG.
T2, T3, T4 can be created.

FIG. 6 is a diagram for explaining the selection of a code conversion table and ruled lines.

When actually creating or updating a document, the user selects in advance which code conversion table to use. This can be done by displaying a ruled line that is actually output and allowing the operator to select it.

When the document creation process or the update process is selected, a screen such as a is displayed. The operator may select a desired one from the displayed plurality of code conversion tables. In the illustrated example, it is assumed that the code conversion table is selected. That is, ADR1 is selected as the address of the code conversion table.

To create a ruled line while a document is being created or updated, press the "Create Ruled Line" key. Then, a menu such as b is displayed based on the selected code conversion table. The operator selects a desired ruled line from the plurality of displayed ruled lines. In the illustrated example, it is assumed that the first ruled line has been selected.

When the first ruled line is selected on the screen b, a ruled line like C is displayed on the screen.

When this ruled line is recorded on the hard disk 12, a recording code 00 (binary number) is recorded, but when it is output, a ruled line output code 000 (binary number) is output from the code conversion table. As a result, a ruled line storage code required to represent eight types of ruled lines can be represented by 2 bits, and the storage capacity can be reduced as compared with a case where conversion is not performed. In addition, a document in which a ruled line is represented by 2 bits can be used with eight types of ruled lines.

〔The invention's effect〕

As is clear from the above description, according to the present invention, (a) the number of codes for recording ruled lines is reduced,
Saves storage space.

(B) The number of types of ruled lines that can be used as a whole can be increased without changing past document data.

A remarkable effect can be achieved.
