Abstract

PURPOSE:To find out whether there is a character on the column direction frame of a designated rectangular area, and execute the rectangular processing quickly and efficiently by extracting the characters which is on the column direction frame of the area from a sentence storing means for character columns corresponding to the designated rectangular area, for the character columns corresponding to the column direction frame of the area. CONSTITUTION:When the rectangular area is designated within the display character column with plural rows displayed is designated by an area designating means 1, the character on the column direction frame of that rectangular area is extracted from a sentence storing means 3, and whether to fetch that character into the rectangular area or not will depend on the instruction of the operator. Next, when the operator executes an instruction to fetch it, the extracted character becomes effective, and when the operator executes an instruction not to fetch it, the extracted character becomes ineffective, and each are stored in a discriminating means 6. Thus, for the characters on the column direction frame of the rectangular area, just the effective characters can be included in the processing by referring to the discriminating means 6.

Description

Detailed Description of the Invention (a) Industrial Application Field This invention relates to a character processing device, and more specifically, a character processing device that can perform rectangular processing such as moving or copying data within a specified rectangular area. Regarding.

(B) Conventional technology Conventionally, rectangular processing in this type of character processing device refers to a process of erasing character data within a specified area, moving it, and rubbing it. It is limited by specifying the upper left end and lower right end of the rectangle using , and the line direction frame is set between characters. In rectangle processing, the object is different from that of so-called area specification. In other words, character data of all lines within the specified area (area specification) is targeted, but in rectangular processing only character data within the specified rectangular area is targeted. The character data within the area limited by such a rectangular frame can be taken into a buffer for use in various editing processes.

(c) Problems to be Solved by the Invention However, in the rectangular processing in the above-mentioned character processing device, there are multiple widths of characters to be processed, such as half-width, full-width single-width, quadruple-width, etc. There are cases where characters hang over the frame in the column direction. In this case, in conventional rectangle processing, all characters that hang in that frame are considered to be outside the rectangular area and are not marked, or the rectangular area specification itself is invalidated and the operator is requested to respecify the area. child.

However, when specifying a rectangular area where a text requires it, the operator has to spend time and effort on this task.

The present invention has been made in consideration of the above circumstances, and therefore provides a character processing device in which an operator can specify that characters overlapping the column direction frame of a rectangular area do not need to be imported.

(d) Second Means for Solving the Problems FIG. 1 is a process diagram showing the basic structure of the present invention. In the same figure, the present invention can be inputted by human power means.
In a character processing device configured to convert two-character data into a character string, store it in a text storage means, and visually output it to a display means, a rectangular area is displayed in multiple lines and a character string is displayed. A rectangular area storage means 2 for storing a specified rectangular area [, a rectangular area storage unit 2 for storing a specified rectangular area, and a character string that hangs on the column direction frame of the area for a character string corresponding to the specified rectangular area. an extraction means 4 for extracting characters from the storage means 3; an instruction means 5 for instructing whether or not to import characters extracted by the extraction means 4 into a rectangular area; This is a character processing device comprising an identification means 6 which stores the extracted characters as valid, and stores the two extracted characters f as invalid when an instruction is given not to import them.

Specifically, the character processing device in this invention includes a word processor, a computer having a character processing function, and the like. The human power means usually consists of a keyboard or can also consist of a pointing device such as a mouse. The instruction means can be realized by, for example, a function key on the keyboard or a combination of two character keys. In this invention, the sentence strings are kanji, kana characters, katakura ta, alphahet, numeric symbols,
Includes spaces, etc.

(E) Effect According to the present invention, when a rectangular area is specified in a display string displayed in multiple lines by the area specifying means I, the characters hanging on the column direction frame of the rectangular area are extracted from the text storage means. , it waits for an instruction from the operator as to whether or not to import that character into the rectangular area. Next, when the operator issues an instruction to import, the extracted characters are considered valid, and when the operator issues an instruction that does not require import, the extracted characters are considered invalid and are stored in the identification means 6. do. As a result, when a character string within a rectangular area is subjected to rectangular processing, only valid characters are provided for processing by referring to the identification means 6 for characters that fall within the column direction frame of the rectangular area.

(F) EXAMPLES The present invention will be described in detail below based on examples shown in the drawings. ζ
However, this invention is not limited by this.

FIG. 2 is a block diagram of a Japanese language word processor according to an embodiment of the present invention. In the figure, IO is the main body of the device, which is mainly composed of a CPU II, a kana-kanji conversion processing section 12, a kana-kanji conversion section I3, a rectangle processing section 14, and an output control section 15, which are interconnected by a path line 16. There is. Second, a keyboard 17 and text data memory 18 are externally connected to the CPU II.
Roughly, the CRT 19 is connected via the output i11 section 15. With this voice configuration), the keyboard 17, which serves as an input means area designation means and an instruction means, is equipped with a character input key-1 for inputting character strings such as ＼ from ＼ and ζ characters. Editing keys such as the conversion key and non-conversion key to convert f-kana character strings into kanji-like sentences mixed with kanji, and single-shot cursor movement to specify a rectangular area in the is character string that is displayed in multiple lines. key, an area specification key consisting of an execution key, a switching key for instructing whether or not to import characters on the column direction frame of a rectangular area into that rectangular area, and copying data within the specified rectangular area. , rectangle processing keys are provided for movement.

The kana character string inputted from the keyboard 17 by key signals is encoded and given to the CPU II.
- Temporarily stored in an input buffer (not shown) in I.

The kana-kanji conversion processing unit 12 includes an output buffer 120,
In cooperation with the CPU II, the character string stored in the human cover sofa is read out, and by searching the kana-kanji conversion dictionary section 13, it is converted into conversion candidates, and the conversion candidates are stored in the output buffer 120. And once the input is confirmed,
The confirmed kanji or kanji-mixed sentences are transferred from the output buffer 120 to the text data memory [8] as a text storage means.
be transferred to. The kana-kanji conversion dictionary section 13 is configured, for example, in a ROM, and mainly stores 32 kana header data of the 50 ontons and confectionery table 5-character data corresponding to this kana header data.

The configurations of the kana-kanji conversion processing section L2 and the kana-kanji conversion dictionary section 13 described above can be the same as those in conventionally known word processors.

The rectangle processing unit 14, which is a feature of the present invention, functions as a rectangular area storage means, an extraction means, and an identification means.
The storage buffer 140 stores a rectangular area specified by a cursor movement operation on the keyboard 17, and stores a character string corresponding to the specified r-two-type area on the column direction frame of that area (specifically, on the left side). The characters on the frame and / or L on the right frame are extracted from the text data memory 18.

If the operator does not press the switch key for the extracted character, a valid/invalid identification flag (not shown)
The preset setting "1" is maintained, and the extracted characters are considered valid and taken into the rectangular area. Furthermore, when the operator presses the switch key, the identification flag is set to "0" and the two extracted characters are considered invalid. The switching key is configured so that the setting of the identification flag can be changed by linking it with "l" - 0" - bi each time it is pressed. In other words, if the identification flag is marked with "bi", the setting of the identification flag can be changed in the column direction. All characters placed on the frame are taken into the rectangular area, and if the identification flag is set to "0"n, all characters placed on the column direction frame are treated as invalid. The switching key of the keyboard 17 is
It functions even if it is after specifying a rectangular area and before rectangular processing such as copying or moving. When rectangular processing is performed, character strings within the designated rectangular area are temporarily stored in the storage buffer 140.

Connected to output control section 15 r-7=CRTI9! It functions as a display means, displays the f2 kana character string input from the keyboard 17, that is, the character string in the human buffer, displays conversion candidates in response to the operation of the conversion key, and specifies a rectangular area. At the first step, a cursor mark is fixedly displayed at the upper left end and lower right end of the rectangular area.

FIG. 3 is a schematic flowchart for explaining the operation of rectangular processing in one embodiment, and the detailed flowchart of each process shown in FIG. 3 is shown in FIGS. 4 to 6j. FIG. 7 is the nth explanatory diagram for explaining the rectangle processing of one embodiment, where yu is a full-width character manually inputted in the sentence creation mode as an f bifurcated character string, b is also a half-width character, and F is a rectangular area. The frames that limit this, FU, FB, FR, and FL, are the upper frame, lower frame, cloth frame, and left frame, respectively. Upper frame FU and lower frame FB
is located between the lines. C and d (for the sake of explanation, these are partition lines and row partition lines in 1-half-width units).

In this example, specify a rectangular area and add the character “so” next to f.
I will explain the state where it hangs on the cloth frame FR.

In FIG. 3, rectangular processing is performed; first, a rectangular area is specified by the operator (step 30).
The position of the two-set area is captured (step 31), and then the divided character determination process is performed, that is, the process of determining whether there are any characters that hang on the column direction frame of the rectangular area (step 32).
and if the judgment result (step 33) is YES,
The system waits for an instruction from the operator as to whether or not to enable divided characters (step 34), and when the operator instructs whether to enable or disable split characters, the selection is memorized (step 35).
), then rectangular editing such as copying and moving the rectangular area (
Step 36) is processed.

The details of the rectangle processing will be explained below. Note that the characters used in the subsequent flowcharts are defined as follows.

YUKOMUKO indicates a flag indicating whether or not the divided character is valid, where 0 is invalid and ■ is valid.

RI: Working pointer CNTl Working counter 1 CNT2/Working counter 2 FIG. 4 shows details of the rectangular area position acquisition process (step 31). In the figure, first, at the time of initial reset, it is checked whether the rectangular area is specified correctly (step 40). Next, when the specified number of rectangles is 0 (step 41), position the cursor at one corner of the rectangular area and press the execution key. The cursor line position is determined and set as the position indicating the upper left end of the rectangular area, and the cursor line position is set as the position indicating the upper left end of the rectangular area (step 42). Further, a rectangle designation number counter is set to 1 (step 43). This means that one diagonal corner position of the rectangular area is memorized.

Next, when you position the cursor at the other corner of the rectangular area and press the execute key, the half-width position of that cursor position is determined, and it is set as the position indicating the lower right edge of the rectangular area, and the cursor line position is set to the rectangular area. (step 44). As a result, the other corner position on the diagonal line in the rectangular area is stored and becomes f here.

Next, determine the half-width position indicating the lower right of the rectangular area > the half-width position indicating the upper left of the rectangular area (step 45), and only if No, the half-width position indicating the upper left of the rectangular area, and the half-width position indicating the lower right of the rectangular area. (step 46). Next, determine the line position indicating the bottom right of the rectangular area > the line position indicating the top left of the rectangular area (Step 47), and only if No, the line position indicating the top left of the rectangular area and the line indicating the bottom right of the rectangular area are determined. (step 48). Through the above processing, the positions of both ends on the diagonal line are correctly stored, thereby limiting the rectangular area.

FIG. 5 is a flowchart showing details of the divided character determination process. In the figure, when a rectangular area is designated, the address of text data indicated by the half-width position and line position indicating the upper left of the rectangular area is set in the text data pointer (step 50). Next, the number of lines in the rectangular area is set in the work counter 2 (step 51).
. Next, the address of the text data pointer or the work pointer is set (step 52). Here, it is determined whether it is the address indicated by the work pointer or the beginning of a character within the rectangular area (step 53). Determining the beginning of the character: Yo, specifically, the address that indicates the work pointer is an address that is indicated in half-width width units, and whether the actual character is arranged in the half-width width like this: Yowakasu Therefore, the determination is made by allocating the character data stored in the text data memory in order from the beginning of the line and checking whether it fits within the frame of the rectangular area. If the result of the determination is No, it is determined that the characters will be placed in the left frame FL of the first line. If the result of the determination is YES (in the case of Figure 7, it is determined to be YES), then the length of one line in the rectangular area is determined in half-width units, and is added to the work counter l. (Step 54). Next, the half-width number of the character pointed to by the work pointer is subtracted from the work counter l (step 55), and the address is incremented by 1 so that the work pointer l points to the next character (step 56). Next, when the work counter 1>O (step 57), the processing of steps 55-+56 is repeated, and when the work counter 1 becomes 0 (step 58)
, move the text data pointer so that it points to the upper left of the second line in the rectangular area (step 59
). If the work counter l does not become 0, it is determined that there are characters hanging on the cloth frame FR (in the case of FIG. 7, this corresponds to the characters "so" and "and").

Next, when the text data pointer is moved to the next line, work counter 2 is decremented by 1 (step 60),
Until the work counter reaches 2 or 0 (step 61)
Repeat the above process. This allows the cloth frame FR or main frame F
All the letters that apply to L can be put into the key line by line.

FIG. 6 is a flowchart showing details of the validation/invalidation process. In the figure, when the characters in the column direction frame are erased, instructions from the operator are awaited. At this point, the operator is informed that a character is placed over the column direction frame in the specified rectangular area. If the operator does not press the switch key, the characters in the cloth frame FR and main frame FL are regarded as valid, and the identification flag is set to "l" (step 71). When the switching key is pressed, the characters in the cloth frame FR and main frame FL are regarded as invalid, and the identification flag is set to "0" (step 72). Once it is determined whether the characters in the column direction frame are valid or invalid in this manner, when rectangular editing is to be performed thereafter, processing is performed according to the contents of the identification flag. In other words, if there is a character that spans the column direction frame of a rectangular area, if the identification flag is "0", that character is skipped and excluded from the processing target, and secondly, if the identification flag is "l", that character is Characters are processed to be captured into a rectangular area.

Although this embodiment has been explained using a Japanese word processor as an example, the object of rectangular processing is not limited to this, and may be character data in a language other than Japanese, and the character data may be symbolic data. Good too.

In this example, we have explained the batch process of validating all the characters in the frame in the rectangular area or completely disabling them. You can enable only the characters that span the main frame, or enable or disable only the characters that span the main frame, or enable or disable each line in a rectangular area.
Modifications to this embodiment may also be made.

(G) Effects of the Invention According to this invention, an operator can know whether or not characters are placed on the column direction frame in a specified rectangular area, and can determine whether or not to import those characters into the rectangular area. Since this selection can be made with only simple key operations, rectangular processing can be performed quickly and efficiently.
