Abstract

PURPOSE:To automatically execute the up shift, centering or down shift of a character string within a processing area by detecting the digit direction width of all lines in the processing area and setting up a condition that the detected width is the same. CONSTITUTION:Within a processing area storing a character string to be moved, a CPU 1 executes transformation processing by a control program read out from a ROM 2 under the condition that the the digit direction width of all lines is the same. Namely when 'centering' is specified from a keyboard 6, an input character string is automatically moved to the center part in the line direction to execute a 'centering function' in the line direction. When 'left shift' is specified, the input character string is moved to the upper side in the line direction to execute an 'up shift' in the line direction, and when 'right shift' is specified, the character string is moved to the lower side in the line direction to execute a 'down shift' function. Thereby transformation processing in the line direction can be automatically executed within a processing area surrounded by ruled lines or indent marks.

M3), which is present on the M3) and performs the intended processing by the control program read by the CPU 1 through the system bus 14.

In the embodiment described here, (1) when "centering" is instructed from the keyboard, the input character string is automatically moved to the center in the row direction, and "centering" in the row direction. When the function is executed and (2) "Left justification" is instructed from the keyboard, the input character string is automatically moved to the upper side in the line direction, and "Up justification" in the line direction is performed.
When the function is executed and (3) "right justification" is instructed from the keyboard, the input character string is automatically moved to the lower side in the row direction and the "lower justification" function in the row direction is executed. It is a thing.

In other words, in this embodiment, "centering" in the column direction → "centering" in the row direction "left alignment" in the column direction → "top alignment" in the row direction "right alignment" in the column direction → This is to automatically convert and execute the "downward alignment" in the row direction. However, these conversion processes are not performed unconditionally.
It is carried out under the conditions detailed later with reference to the following.

FIG. 2 is a flowchart showing the overall control procedure of this embodiment. Hereinafter, description will be given according to the illustrated steps. Here, for convenience of description, it is assumed that normal character input and editing are performed and, for example, an input screen as shown in FIG. 8 is already displayed on the CRT 8.

First, the "centering" of the input character string is performed by operating the keys arranged on the keyboard (KB) 6,
It is detected that "right justification" or "left justification" processing has been instructed (step S21). Next, the content of the instruction is determined (step S22), and for instructions other than "centering", "right justification" or "left justification", individual processing corresponding to that is executed (step S23).

If it is determined in step S22 that the "centering", "right justification" or "left justification" instruction has been input, then in step S24 it is determined whether the cursor is in a normal position (for example, on a ruled line). (Whether it is located or not) is determined. Note that in order for the cursor position to be normal, not only is the cursor not located directly above the ruled line as described above, but it is also included in the area surrounded by the ruled line or indent (hereinafter referred to as the processing area). It is necessary to have

If it is determined in step S24 that the cursor position is abnormal, that is, if the cursor is not in the valid position, this process ends.

If it is determined in step S24 that the cursor position is normal, then the character string is moved in the digit direction in the processing area in which the cursor is positioned, or the character string is moved in the row direction. It is determined whether to move (steps S25 and S26). The "processing direction determination" in step S25 will be described in more detail later with reference to FIG.

As a result of the determination, the digit direction (= horizontal direction)
When it is determined to move the character string to, the process proceeds to step S27, and centering / right justification / left justification which is a known digit direction editing process is performed.

On the other hand, when the character string moving process in the row direction (= vertical direction) is determined, in step S28,
A character string moving process (centering / top / bottom) in the row direction is performed. The processing contents of this step S28 are
A detailed description will be given later with reference to FIG.

FIG. 3 is a flow chart showing in detail the processing direction discrimination processing (step S25) of FIG.

First, in step S31, the first row and first column position in the processing area where the cursor is positioned (see FIG. 4).
Is detected, and the position data is stored in the “leading position” storage area of the RAM 3. On the input screen illustrated in FIG. 8, the continuity of the processing area is detected from the cursor position P2 toward the head direction and the sentence head direction, and the head position P1 is detected.

Next, the same position data as the "start position" is stored in the "current processing position" storage area of the RAM 3 (step S32).

In the next step S33, it is detected how many digits the width of the processing area of the line including the "current processing position" is. For example, referring to FIG. 4, the number of digits of four full-width characters is detected. Further, in the example illustrated in FIG. 8, the number of digits corresponding to one full-width character is detected. Then, the number of detected digits is stored in the "number of digits in area" storage area of the RAM 3 (step S34).

Subsequently, in the next step S35, it is detected whether or not one character (including a blank character) is completely input in the relevant line (the line including the current processing position) in the processing area. When one character is input without any space in the line, the "character arrangement flag" is turned off. For example, in the second line of FIG. 5, since one horizontal double-width character "a" is input in the area of two full-width characters, the "character arrangement flag" is turned off. However, since the two full-width characters "A" are input in the first line of the figure, the "character arrangement flag" is turned ON. The “character arrangement flag” thus obtained is stored in the “character arrangement flag” storage area of the RAM 3.

In step S36, it is detected whether or not there is a line next to the line including the current processing position. If there is a next line,
In step S37, the "current processing position" is updated. Then, the digit number of the line including the updated current processing position is detected (step S38), and it is determined whether or not the detected digit number is equal to the already stored "area digit number" (step S38).
39). Obtaining the determination result of "YES" in step S39 means that the width of the line included in the processing region does not change.

When a "YES" determination result is obtained in step S39, the process proceeds to the next step S40,
The "character arrangement flag" of the line (the line including the updated current processing position) is detected. Then, the contents of the flag are stored in the RAM
3 is stored in the "character arrangement flag" storage area. Therefore, when the same flag as the "character arrangement flag" stored in step S35 is detected, the contents stored in the "character arrangement flag" storage area of the RAM 3 are not changed.

If it is determined that there is no next line in step S36, the process proceeds to step S41, and it is determined whether or not "start position" = "current processing position". If the result is "YES", only one row is included as the processing area, and the row direction processing is impossible. Therefore, in step S43, the "digit direction" is stored in the "determination result" storage area of the RAM 3. Is stored.

When "NO" is obtained in the determination in step S41, the process further proceeds to step S42, and it is determined whether or not the "character arrangement flag" is "ON". As a result, if “YES”, there is a plurality of characters other than one character (including a blank character) in any of the lines in the processing area. Therefore, the process proceeds to step S43.
The “digit direction” is stored in the RAM 3 as the “discrimination result”.

On the other hand, in step S42, "NO",
That is, when it is determined that the “character arrangement flag” is “OFF”, only one character is entered in each line in the processing area (for example, a half-width character is entered in the half-width area). Since one character is input as one double-width character in the area having a width of four half-width characters (see FIG. 5), step S44
In, the “row direction” is stored in the “discrimination result” storage area of the RAM 3.

If "NO" is determined in the step S39, it means that the widths of the respective lines in the processing area are not the same, so the control is moved to the step S43.

FIG. 6 shows the row direction processing of FIG. 2 (step S2).
8 is a flowchart showing in detail 8).

First, in step S61, it is determined whether or not there is a target character string to be moved in the row direction. If there is no target character string, this process ends.

In step S62, the range of the target character string is detected (see FIG. 7). That is, the position of the character or control character that first appears from the start position toward the final position is the start point position, and the position of the character or control character that first appears from the final position direction toward the start position direction is the end point position. The range of the target character string to be detected is detected.

Next, in step S63, the keyboard 6
If the instruction given from is "right justification", step S64
If "centering" is selected, the process proceeds to step S65, and if "left alignment" is selected, the process proceeds to step S66.

In step S64, the lowering top position calculation process is performed. In this processing, the destination position of the starting point position of the target character string is obtained, and the process proceeds to the next step S67 (see FIG. 9). The destination position is calculated by the following formula, for example.

[0052]

## EQU1 ## Destination position = final position-end point position + start point position In step S65, centering start position calculation processing is performed. In this process, the destination position of the starting point position of the target character string is obtained, and the process proceeds to the next step S67 (see FIG. 10). The destination position is calculated by the following formula, for example.

[0053]

[Formula 2] Destination position = (final position + start position−end point position + start point position) / 2 (truncated) In step S66, top-aligned start position calculation processing is performed.
In this processing, the destination position of the starting point position of the target character string is obtained, and the process proceeds to the next step S67 (see FIG. 11). The destination position is calculated by the following formula.

[0054]

## EQU00003 ## Moving destination position = starting position In step S67, a moving process of moving a character string of (end point position-start point position + 1) lines is performed.

Other Embodiments (1) In addition to the ruled lines used in the embodiments described so far, the continuity of the boundaries of the processing area defined by, for example, indent control characters or tab positions may be determined. . That is, when determining the continuity of the processing area, various kinds of information can be modified and used if possible.

(2) In the formula for obtaining the centering movement destination position described with respect to step S65 in FIG. 6, when the target character string is not just centered, the line is shifted to the upper line by one line. It doesn't matter.

Further, although various movement processes are instructed from the keyboard, for example, the pointing device 1
By designating a specific position on the screen by 3, various movement processes may be selected. That is, the function selection can be variously modified.

(3) In the processing direction determination processing shown in FIG. 3, only one character (see the second line in FIG. 5: including a blank character) needs to be embedded in each line of the processing area. However, as shown in the first line of FIG. 5, when the shifting process in the column direction is impossible, the moving process in the row direction can be performed. For example, when the screen as shown in FIG. 12 is displayed, since it is impossible to perform the shifting process in the digit direction, the lowering shown in FIG. 13, the centering shown in FIG.
It is also possible to perform the top alignment shown in FIG.

(4) Further, in FIGS. 2 and 6, "left justification" in the digit direction corresponds to "top justification" in the row direction, and "centering" in the digit direction corresponds to "centering" in the row direction. The "right justification" in the column direction has been made to correspond to the "bottom justification" in the row direction, but these correspondences can be set completely freely.

(5) The present invention may be applied to a system composed of a plurality of devices or an apparatus composed of a single device. Further, it goes without saying that the present invention can be applied to the case where it is achieved by supplying a program to a system or an apparatus.

(6) Further, the shape of the processing area is not limited to a rectangle or a square, but may be a parallelogram having the same width in the digit direction (see FIG. 16).

[0062]

As described above, according to the present invention, when a character string is arranged in the line direction in a processing area surrounded by ruled lines or indent marks in the main text, the text is automatically arranged in this area. Since centering / lower / upper alignment can be performed in the row direction, it is possible to obtain a character processing apparatus and method that do not require fine adjustments while switching screens and checking the entire layout display.

That is, according to the present invention as set forth in claims 1 and 7, it is possible to automatically perform the upper alignment, centering, or lower alignment of a character string within a processing area surrounded by ruled lines or the like.

According to the present invention as set forth in claims 2 and 8, in a region sandwiched by ruled lines or indent marks, the character string is automatically moved in the row direction, that is, upper alignment, centering, or lower alignment. It is possible to gather.

According to the present invention as set forth in claims 3 and 9, it is possible to enable / disable the character string movement processing in the row direction depending on the character arrangement state in each row.
