DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creating apparatus capable of moving character data in a rectangular block by moving a format sequence forming a rectangular block.

[0002]

2. Description of the Related Art In a document creation device such as a Japanese document creation device or a workstation, a rectangular block is generated by a format mark, and character data can be input to documents having various layouts.

For example, a document having a format as shown in FIG. 6A will be described as an example. A rectangular block formed by indentation (◇) is provided on a document text T, and a character is included in the rectangular block. Data has been entered. By moving the indent row forming this rectangular block to the left and right, a so-called format change function is provided in which the character data in the rectangular block also moves according to the new rectangular block format as shown in FIG. There was a document creation device.

[0004]

The handling of null data in the format change of such a conventional document creation device is as follows.
Character data has been moved according to the rule that (I) null data at the end of a line means that the document has been broken, and (II) other null data is treated as characters. Therefore, according to this rule, the processing of character data in a rectangular block in which no space exists on the left side of the block as shown in FIG.

However, as shown in FIGS. 2A and 3A, character data having a blank space on the left side in a rectangular block cannot be processed well. That is, the left margin was destroyed by the movement.

The document creation apparatus of the present invention has been made in view of such circumstances, and moves character data in a character block in a rectangular block while protecting a margin generated on the left side. According to the present invention, for example, the character data in the rectangular blocks shown in FIGS. 2A and 3A can be converted into the document data shown in FIGS. 2B and 3B.
The moving process can be performed as shown in FIG.

[0007]

According to the present invention, there is provided a document creating apparatus which includes a plurality of lines of a document text, in which format marks such as ruled lines, indents and margins and character data are mixed, and a rectangle formed by the format marks is provided. When a format column of a block is changed, in a document creating apparatus that moves character data in the rectangular block according to the block width of the changed format column, the document data is stored in a rectangular block of the changed format column. A line position search unit for searching the position of the character data to be written in the rectangular block before the change, and a left margin for writing the character data in the rectangular block in the format column after the change. An optimal null number determining means for determining the number of characters, the optimal null number determining means comprising a line for which character data to be written is searched by the line position searching means. If the character data is the first character data to be read, the number of null data at the beginning of the line is set to the optimum null number, and the character data to be written is the character data read from the searched line for the second time or later. For example, the number of null data at the head of the next line after the searched line is set as the optimum null number, and if the next line is a null line, the first null line of the searched line is set as the optimum null number, and the searched null is set. If the end of a given line is null data, the number of null data at the beginning of the line is determined as the optimum number of nulls.

[0008]

Since the number of left margins at the time of writing character data in a rectangular block based on the format string after the change is determined by the optimum null number determining means, a rectangle for moving the format row forming the rectangular block is determined. In the processing of the character data in the block, it is possible to reflect the number of left margins where the user has inserted a null consciously. Can be processed.
