Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a document processing method, and more particularly to a document processing method capable of inputting parentheses of different lengths.

2. Description of the Related Art Conventionally, in a document processing apparatus that displays and prints characters and symbols composed and expressed by a combination of a plurality of characters and the like, for example, a vertically long symbol having a character length of five lines is input and printed. As means for displaying, a part corresponding to each symbol is input and displayed five times at five places.

[Problems of the Related Art] For this reason, in order to input characters and symbols composed and expressed by a combination of a plurality of characters and the like as described above,
An input operation including cursor movement must be performed at least for the number of composed characters.

Also, in the input operation, it is necessary to memorize which character should be input in which part.

[Means for Solving the Problems] In order to solve the above-mentioned problems of the prior art, the present invention displays a plurality of candidates for parentheses of the same type but different lengths on a window, and displays a cursor in the document. Based on the position and the parentheses selected from the displayed plurality of candidates, a position in the document to output the parentheses is determined, and the position in the determined document is selected. A document processing method for storing codes of parentheses is provided.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

It should be noted that documents, characters, character strings, and the like in the present embodiment may include symbols or illustrations.

The controller (hereinafter, referred to as RPTC) analyzes character data and control data (print characters, movement amount after printing, etc.) sent from the CPU 1 through the system bus 11, and drives the PRT 9.

FIG. 2 shows a corresponding bracket character table stored in the ROM 2. By referring to this table, the correlation between the candidate number and the corresponding bracket symbol can be clarified, and the bracket symbol to be input can be determined.

Next, the operation of the present invention will be described with reference to FIGS.

FIG. 3 is a flowchart of a process for inputting and displaying parentheses by rewriting a plurality of document data areas. First, in S31, it is determined whether or not the key input this time is a key input for implementing the present invention. If it is determined that the key input is to implement the present invention, the process proceeds to S32.

If it is determined that the input is not a key input for implementing the present invention, preparation for the next input character processing is performed.

In S32, the candidates for the parentheses for which the present invention is to be implemented are displayed using, for example, a window.

In S33, a candidate is selected from the parenthesis symbol candidate windows displayed in S32 by using a cursor or the like in the window.

In S34, the candidate for the bracket symbol selected in S33 is
It is determined whether it is possible to rewrite the document data based on the conditions described later.

At S35, a branch is made as to whether the document data rewriting process determined at S34 is possible. If it is determined that rewriting is possible, go to S36. If it is determined that rewriting is not possible, an error message to that effect is displayed by referring to the error code output in S34 to prepare for the next input character processing.

In S36, the document data in the DB 6 is rewritten by referring to the candidate number of the parentheses selected in S33 and the address of the document data to be rewritten obtained in S34.

At S37, the document data including the parentheses rewritten at S36 is converted into dot pattern data by the character generator in the ROM 2 and displayed.

4. FIG. 4 is a flowchart of a parenthesis symbol candidate selection process for implementing the present invention.

First, in S41, a default value of a bracket symbol candidate is set. At this time, it is necessary to indicate the default value of the set parentheses in the window with, for example, a cursor in the window so that the default value portion becomes clear.

In S42, the key code input from KB4 is processed through KBC5. This is a key input portion for determining whether the individually input key is a key for changing the parenthesis symbol candidate or a key for determining the parenthesis symbol candidate.

In S43, it is determined whether or not the key input performed in S42 is a key for changing a parenthesis symbol candidate.

If it is not determined that the key is a key for changing the parenthesis symbol candidate, the process proceeds to S45.

If it is determined that the key is a key for changing the bracket symbol candidate, go to S44, change the bracket symbol candidate as instructed by the key entered in S42, along with it,
The candidate display of the window is also changed at the same time.

In S45, it is determined whether or not the key code input in S42 is a key for determining a parenthesis symbol candidate.

If it is not determined that the key is a key for determining a bracket symbol candidate, the process proceeds to S42.

If it is determined that the key is a key for determining a bracket symbol candidate, in S46, the determined bracket symbol candidate number is stored in RAM.
Write in the designated area of 3 and finish.

FIG. 5 is a flowchart for determining whether or not the parentheses determined in the above procedure can be written in the document data area.

First, in S51, a rewriting address of the document data is obtained based on the determined candidate (length) of the parentheses in order to clarify which part of the document data area should be rewritten.

In S52, it is determined whether or not there is a document data area indicated by the rewrite address of the document data determined in S51. If the document data of the rewriting address exists, the process goes to S56. If the document data of the rewriting address does not exist, the process proceeds to S53, and it is further determined whether or not the document data can be newly updated / extended to the portion indicated by the rewriting address.

If the document data area cannot be expanded / updated, the process goes to S55, sets the rewritable flag to OFF (non-rewritable mode), sets an error code indicating that, and ends the processing.

If the document data area can be extended / updated, the document data area is extended / updated in S54 so as to satisfy the above conditions.

In S56, it is determined whether a character other than a space already exists at the rewrite address of the document data obtained in S51.

If a character other than a space already exists in the above address, the process goes to S57, sets the rewritable flag to OFF (non-rewritable mode), sets an error code indicating that, and ends the processing.

If there is no character other than a space in the above address, go to S58, set the rewritable flag to ON (rewriteable mode), and end.

Even if characters other than space exist in the above address, if the specification is forcibly entering parentheses (forced rewrite mode specification), S5 in the flowchart of FIG.
6, S57 and S58 are unnecessary.

[Other Embodiments] In the above-described embodiment, an example of input operation of a vertically long parenthesis symbol over a plurality of lines has been described. Can also be applied to the input of.

Further, the present invention is also applicable to “external characters” that can be freely registered and used by a user of the document processing apparatus of the present invention. In this case, the character pattern is stored in the RAM 3 instead of the ROM 2 in the description of the embodiment.

[Effects of the Invention] As described above, according to the present invention, a plurality of candidates of parentheses of the same type but of different lengths are displayed on the window, and the position of the cursor in the document and the displayed A position in the document to output the parentheses is determined based on a parenthesis selected from a plurality of candidates, and a code of the selected parenthesis is stored in the determined position in the document. By doing so, the appearance symbol of the desired length is displayed as a candidate and provided to the operator as an option. Therefore, even when inputting parentheses symbols having different lengths, it is not necessary to specify the two points of the start point and the end point. Instead, it is possible to specify the length only by selecting from multiple candidates,
Operability can be improved.
