The RAM 3 has a document memory for storing information regarding a document to be edited. That is, RAM3
Constitutes a storage means. FIG. 2 is an explanatory diagram showing an example of a storage format of the document information in the RAM 3.

As shown in the figure, the RAM 3 has a text information area for storing text information, a page information area for storing information of each page in a document, a format information area for storing format information, and a form overlay. A form overlay graphic area for storing information about the graphic.

In the text information area, line format information and in-line character data are stored for each line. As shown in FIG. 3, the line format information includes a flag indicating whether or not a line pitch value is specified, a line pitch specification value (for example, a value in 0.1 mm unit) specified for each line, and a print line pitch value. (The value converted to the print pitch value when the line pitch specified value was printed),
The line modification information is stored. When performing edit operations that change line positions (for example, document initialization, document recall, line deletion, line insertion, line pitch value change, line move, etc.), the first line to the last line in the range that needs to be changed If the line pitch specification value or print line pitch value stored as the line format information of each of the lines up to is changed, and it is determined that there is a line that crosses the page boundary due to the format information in the process of the editing operation. The line number of the line stored in the corresponding page information area is updated. This allows the RAM to be stored at the end of the editing process.
Information regarding the line position at the time of printing is recorded in 3 in page units and line units.

In the page information area, the margin values on the top, bottom, left and right of the page and the row position of each row of the page are stored.

In the format information area, there is a flag (form overlay presence / absence flag) indicating the presence / absence of data (form overlay graphic data) for displaying and printing a figure of a fixed form on the document of each page. If the flag indicates that there is form overlay graphic data, a form overlay graphic area that stores the form overlay graphic data including the format, attribute, and position information is created in an area other than the text information area. .

The case of editing a standard form document on the default format with form overlay will be described below. FIG. 4 is a flowchart showing an editing processing procedure executed in this embodiment. The program for executing this flowchart is ROM2,
It exists on FD10, HD11 or RAM3, and CPU1
ROMs sequential programs via system bus 14
2, FD10, HD11 or RAM3.

Prior to execution of the flow chart, a fixed form document is created with a form overlay on top of the default form.

FIG. 5 is an explanatory diagram showing an example of a document created by the form overlay. In the figure, P6
Is a ruled line showing a fixed form, and P7 shows a boundary of paper. As is clear from FIG. 5, in the default format, for example, a line is placed at an improper position such as not fitting within each cell delimited by the ruled line P6 (P1, P2, and P4 in FIG. 5). Therefore, the line whose position is not appropriate is edited.

Returning to FIG. 4, first, by discriminating which key on the keyboard 6 has been input, the discrimination of the selected function (function selection processing) is performed (step S1).

In step S1, "row pitch erase"
Keys other than the key and "row pitch move" key are entered,
When it is determined that another function is selected, the function process is performed (step S2), and then the process of step S6 described later is performed. In addition, at initial startup, ROM
"Initial start" by the initial program stored in 2.
The key is virtually sent to the CPU 1, and the initial activation process is performed in step S2.

In step S1, "row pitch erase"
When it is determined that the key has been pressed and the row pitch erasing function has been selected, an erasing range designating process for designating a range of lines to be erased (erasing range) is performed (step S3). To specify the erase range, place the cursor on the line that will be the start point of the range (hereinafter referred to as the start line), press the execution key on the keyboard 6, and then the line that will be the end point of the range (hereinafter referred to as the end line). This is done by moving the cursor to and pressing the execution key. For example, as shown in FIG. 5, when deleting a row P1 whose position is not appropriate, the cursor is moved to the row P1 as the start point row and the execution key is input, and then the cursor is moved to the row P1 as the end point row. The execution key is input as it is. As a result, the row P1 is designated as the erase range. Further, in step S3, the line position of the start point line (hereinafter referred to as the start point line position) and the line position of the end point line (hereinafter referred to as the end point line position) designated as the erase range are RA.
It is stored in a predetermined area of M3. By inputting the cancel key instead of inputting the execution key, this process is canceled, and the function selection process of step S1 can be performed again.

When the designation of the erasing range is completed, a process for erasing the document in the designated erasing range (erasing process) is executed (step S4). When this process is executed, for example, when the line P1 is designated as the erase range in the example shown in FIG. 5, the document shown in FIG. 5 is converted into the document shown in FIG.

Here, the erasing process executed in step S4 will be described in detail. In the following description, the starting point row position of the erasing range is a, the ending point row position is b, and the row position of the row immediately before the starting point row is c.

First, based on the row positions a and b, it is judged whether or not the designation of the erase range is an error. For example, 1
In the case of a format in which only one line exists on a page, it is judged that the designation of the erase range is an error. If it is determined that there is an error, a predetermined error process is performed, and the process of step S3 is repeated in order to specify the erase range again.

Next, the print line pitch values in the line format information corresponding to each line between the start point line position a and the end point line position b are added, and the result is the print line pitch of the line at line position c. It is added to the value. The resulting printed line pitch value is converted to a line pitch value, and the converted value is set as the line pitch value of the line at line position c.

At this time, if there is no line at the line position c, that is, if the starting line of the erasing range is the first line of the page, the above result is added to the upper margin value, and the result is regarded as the upper margin value. It is newly set. After these settings are completed, the information about the lines in the range from the line position a to the line position b designated as the deletion range is deleted from the document memory of the RAM 3.

Returning to FIG. 4, it is judged whether or not the erasing process of step S4 is normally completed (step S5). If the answer is negative (NO), that is, the erasing range is designated as an error. If determined, the above step S
Returning to the processing of No. 3, the erasing range is set again.

If the answer to step S5 is affirmative (YES), a display process for displaying the document information after the erasing process on the display section 8 is performed (step S6). In this display process,
In order to display the line direction as a print image, first, the print line pitch value stored in the RAM 3 as line format information is converted into the resolution of the display screen of the display unit 8, and the display position of each line on the display screen is calculated. It Calculation of display position is C
The result calculated by the PU 1 is sent to the display unit 8 via the system bus 14 and the display control unit 7. The display unit 8 displays the document information of each line as a print image based on the calculated result.

If it is determined in step S1 that the "row pitch movement" key of the keyboard 6 has been input and the row pitch movement function has been selected, the range of rows to be moved (movement range) is determined. A designated moving range designation process is performed (step S7). For example, when it is desired to correct the position of the row P2 after erasing the row P1 as shown in FIG. 6, after the cursor is moved to the row P2 as the start point row and the execution key is input, the row P2 is changed to the end point row. The cursor is moved and the enter key is input. This allows
Only the row P2 is designated as the movement range. Furthermore, in step S7, the start point row position and the end point row position of the designated movement range are stored in a predetermined area of the RAM 3. By inputting the cancel key instead of inputting the execution key, this process is canceled, and the function selection process of step S1 can be performed again.

When the designation of the moving range is completed, a destination designating process for designating the position of the destination is performed (step S).
8). The designation of the destination is performed by designating the position of the upper end of the desired position. For example, in the case of the example shown in FIG. 6, when the cursor displayed on the display screen of the display unit 8 is moved to the position indicated by P3 using the pointing device 13 and the execution key is input, the movement is performed. The designation of the leading position is confirmed. Further, the movement position designated on the display screen in this processing is converted into a value in units of print line pitch values from the upper end of the paper and stored in a predetermined area of the RAM 3. It should be noted that this processing can be canceled by inputting a cancel key instead of inputting the execution key.

Next, a movement process is executed to move the line within the movement range designated in step S7 to the destination position designated in step S8 (step S).
9). By performing this process, for example, the document shown in FIG. 6 is converted as shown in FIG.

Here, the moving process performed in step S9 will be described in detail. In the following description,
The starting point row position of the movement range is a and the ending point row position is b. Also, except for the lines within the range from the start point line position a to the end point line position b, the line position of the closest line existing on the same page as the move destination position P3 and located on the upper end side of the paper from the move destination position is c. To do.

First, based on the values a, b and c, it is determined whether or not the designation of the movement range or the movement destination position is an error. For example, if a position that is less than the minimum value allowed for the top margin is specified as the destination position, or if a line included in the movement range is moved to the destination, the movement range becomes If a value that exceeds the maximum allowable value is specified as the destination position, it is determined that an error has occurred. When it is determined that there is an error, a predetermined error process is performed.

Next, when there is a line at the line position c, a value in print line pitch units from the upper end position of the paper to the upper end position of the line c is obtained, and the obtained value is obtained from the movement destination position P3. The subtracted result is set as the print line pitch value of the line at the line position c, and the print line pitch value is stored in the line format information of the RAM 3. Further, the set print line pitch value is converted into a line pitch value, and the converted value is set to the line position c.
Is set as the row pitch value of the row at. If there is no line at the line position c, that is, if the position designated as the move destination position is the first line of the page, the move destination position P3 is set as the upper margin value.

Next, in order to move each line designated as the movement range to the movement destination position, it is determined whether or not there is a line other than the movement range between the line position c and the starting point line position a. To be done.

When it is determined that there is no line other than the movement range between the line position c and the line position a, each line in the movement range is included in the movement range when moved to the movement destination position. Among the lines other than the line to be moved and existing outside the length of the moving range, the line position d of the closest line located on the lower end side of the sheet from the end line position of the moving destination is obtained. Then, a value in print line pitch units from the upper end of the paper to the upper end position of the line at the line position d, and from the upper end position of the paper to the upper end position of the end line when each line within the destination range is arranged at the destination position. A value in print line pitch units is determined, and the determined value is subtracted from the print line pitch value. The value obtained as a result of the subtraction is set to the print line pitch value of the end line, and the value obtained by converting the set print line pitch value to the line pitch value is set as the line pitch value of the end line.

On the other hand, when it is determined that there is a row other than the movement range between the row position c and the row position a, the row position a and the row position c are compared.

In the case of c <a, when each line in the movement range is moved to the movement destination position, among the lines other than the lines included in the movement range and existing outside the length of the movement range, The line position e of the closest line located on the lower end side of the paper from the end line position of the destination is determined. Then, a value in print line pitch units from the upper end of the paper to the upper end position of the line at the line position e, and from the upper end position of the paper to the upper end position of the end line when each line within the destination range is arranged at the destination position. A value in print line pitch units is determined, and the determined value is subtracted from the print line pitch value. The value obtained as a result of the subtraction is set to the print line pitch value of the end line, and the value obtained by converting the set print line pitch value to the line pitch value is set as the line pitch value of the end line. When the line position of the line preceding the start point line is equal to or greater than e, the value obtained by adding the print line pitch values of the lines from the start point line position a to the end point line position b is the print line pitch value of the line preceding the start point line. Is added to, and the value obtained by converting the value into the row pitch value is set as the row pitch value of the row. And RA
Lines are moved within the M3 document memory. That is, when the lines within the movement range are moved to the position next to the line position c in the document memory and there are lines that overlap the movement range, the information regarding those lines is deleted from the document memory of the RAM 3.

On the other hand, in the case of c> a, when each line in the movement range is moved to the movement destination position, it is a line other than the lines included in the movement range and located on the lower end side of the paper from the end position of the movement destination. The closest line located at is determined, and the value in print line pitch units from the top edge of the paper to the top position of that line is determined. Then, the value in print line pitch units from the upper end position of the paper to the upper end position of the last line when each line in the movement range is moved to the movement destination position P3 is subtracted from the obtained value. The value obtained as a result of the subtraction is set as the print line pitch value of the end line, and the value obtained by converting the set print line pitch value into the line pitch value is set as the line pitch value of the end line. In addition,
If the preceding line of the starting point line exists in the same page, the value obtained by adding the printing line pitch values of the respective lines from the starting point line position a to the ending point line position b is added to the printing line pitch value of the preceding line of the starting point line. , A value obtained by converting the value into a row pitch value is set as the row pitch value of the row. If the preceding line of the starting point line does not exist in the same page, the value obtained by adding the printing line pitch values of the lines from the starting point line position a to the ending point line position b is added to the upper margin value.

Then, the line is moved in the document memory. That is, if each line in the movement range is moved to the position next to c in the document memory and there is a line overlapping the movement range, R
Information about those lines is deleted from the AM3 document memory.

Returning to FIG. 4, it is judged whether or not the moving process in step S9 has been normally completed (step S10). If the answer is negative (NO), steps S7 to S7 are repeated.
The process of step S9 is executed.

If the answer to step S10 is affirmative (YES), the process proceeds to step S6 described above, and display processing for displaying the document information after the movement processing on the display unit 8 is performed.

As described above, according to the present embodiment, when an editing process such as erasing or moving a designated line range is performed, the line spacing within the line range to be processed is maintained. In addition, the line pitches of the lines before and after the line pitch are changed so as to maintain the line spacing outside the line range, so that the document editing work can be facilitated and the time required for the editing work can be shortened.

Note that, in the present embodiment, the process of erasing by designating only one line as the erasing range and the process of locating and migrating only one line as the moving range are shown in FIGS. 5, 6 and 7.
However, the same processing can be performed for a plurality of lines by specifying the line range over a plurality of lines. For example, when a line in the range P4 shown in FIG. 7 is moved by designating the position P5 as the movement destination position with the cursor, each line can be moved to the position shown in FIG.

Further, although the present embodiment has been described with reference to the document in the horizontal writing format, the present processing method is also applied to the document in the vertical writing format by replacing the upper margin / lower margin with the right margin / lower margin. It is possible.

Although the erasing process and the moving process have been described in the present embodiment, it is possible to easily deal with the editing operation such as the copying process and the exchanging process by combining the moving process and the erasing process. There is no end.

The method described in this embodiment can also be applied to a document processing system composed of a plurality of devices, and can be achieved by supplying a program to the system or apparatus. Applicable.

[0054]

As described above, according to the document processing apparatus of claim 1 or the document processing method of claim 5, a line range is designated on the display means and the designated line range is edited. In this case, since only the line pitch at the boundary between the designated line range and the range outside the designated line range is changed, the document editing work is facilitated and the time required for the editing work is shortened. The effect that can be obtained is obtained.
