Description

[Detailed Description of the Invention] The present invention provides a Japanese input device having an editing function within ruled lines, in particular, inputting Japanese sentences while converting words inputted in kana characters into kanji display by operating a kanji conversion key. In a Japanese input device that handles ruled lines as character codes, the above kanji conversion is performed by using the ruled line code stored on the screen code buffer while the ruled line range mode is specified. This invention relates to a Japanese input device with an editing function within ruled lines, which performs processing by limiting information within the ruled line range, and efficiently executes editing processes such as creating slips and charts. .

A Japanese input device converts input kana characters into kanji characters and creates a Japanese sentence mixed with kanji characters. The use of such Japanese input devices has expanded to include processing fields such as creating slips and diagrams. It is desirable to efficiently execute processes such as registering text within a frame, registering text within a frame, and moving text within a frame to another position. When executing such processing, ruled lines have traditionally been treated as if they were one special character, and it is difficult to distinguish between ruled lines and general characters during processing. That's one problem.

The present invention aims to solve the above-mentioned problem, and adopts an aspect in which the existing position of the ruled line code stored on the screen code buffer is registered, so to speak, by the left end buffer and the right end buffer. The aim is to efficiently solve the above problems. Therefore, the Japanese input device of the present invention having an editing function within ruled lines includes a keyboard, a cursor control unit that controls the cursor position by key operations on the keyboard, and a cursor control unit that controls the input kana characters. A function control unit including a kana-kanji conversion processing function for conversion, a display, and a screen code buffer in which code information corresponding to the display on the display screen of the display is stored,
A first X-axis coordinate position on the display screen is stored in the Japanese input device that inputs Japanese sentences while converting a kana character string input by key operations on the keyboard into kanji characters. A left end buffer, a right end buffer that stores the second X-axis coordinate position, a cursor coordinate position from the cursor control section is detected, and a buffer is sent to the cursor control section based on the contents of the left end buffer and the right end buffer. The left and right edge detectors regulate the cursor movement range, and the X-axis coordinate position where the first ruled line code extending in the Y-axis direction, which indicates the ruled line range mode and is written on the display screen, is present. A ruled line range mode indicating section is provided which stores in the left end buffer and also stores in the right end buffer the X-ray coordinate position where the code of the second ruled line extending in the Y-axis direction, which is also written on the display screen, exists; In response to the mode setting by the within ruled line range mode instruction unit, the function control unit transmits information within the ruled line range in response to the cursor movement within the ruled line range by the cursor control unit. The feature is that the processing is executed in a limited manner. This will be explained below with reference to the drawings.

In the case of the present invention, ruled lines are written on the display screen of the display, and information can be limited to be processed within the ruled lines. In the case shown in FIG. 1A, a mode is shown in which Japanese is input within a frame between left and right ruled lines 1 and 2. In other words, this corresponds to a state where the user has finished writing up to ``text'' shown in the figure and is about to write ``input'' next.
When the cursor 3 inputs the kana ``ni'', the content of the Y-axis buffer is increased by 1 based on the existence of ruled line 2, and 1 is added to the X coordinate where ruled line 1 exists.
will be moved to the value added. That is, it is moved to the position of the illustrated character "YU". Next, the kana ``Yu'', ``U'',
When ``ri'' is input and the kana ``yo'' is input, the cursor is moved to the position of the illustrated character ``ku'', and the kana ``ku'' is then input. When the conversion key is pressed in the state shown in FIG. 1A, the illustrated kana ``niyuuriyoku'' is converted into the kanji ``input''. The kanji ``iri'' is placed in the illustrated kana position ``ni'', and the kanji ``power'' is placed in the illustrated kana position ``yu''.
, and the cursor 3 is controlled to be at the illustrated kana ``u'' position.

FIG. 1B shows a mode of inputting enlarged characters. In the case of enlarged characters, one character is represented by the size of two standard characters, and on the display screen, for example, the enlargement indication symbol "←→" is displayed for the character "rule". In addition, enlarged characters are displayed. In one embodiment of the present invention, even when inputting such enlarged characters, it is possible to process them after specifying the ruled line range mode.

FIG. 1C shows a mode of inputting reduced characters. In the case of reduced characters, two reduced characters are expressed within the size of one standard character. For example, two reduced characters such as "01" correspond to the size of one standard character. are doing. In one embodiment of the present invention, even when inputting such reduced characters, it is possible to process them after specifying the ruled line range mode.

FIG. 1D shows a mode in which characters within the ruled lines are registered so that they can be recalled and used later.
For example, by pressing the registration key, specifying the position of the character "rule" and the position of the period "." with the cursor 3, and pressing the execution key, the ruled line 1, 2
For example, the text up to ``ruled line...'' within the range between the lines will be registered in a floppy disk. Of course, similarly moving to another position on the display screen or copying (transferring) the same thing to another position can be executed after specifying the ruled line range mode according to the present invention. be made into

FIG. 1E shows a mode in which an underline is input to a character within a ruled line, and the illustrated case corresponds to a state in which an underline is added to the character "bottom". In one embodiment of the present invention, such underline addition processing can also be performed after specifying the ruled line range mode.

FIG. 1F shows a mode in which, for example, a title or the like is written in a frame, and in the case shown, the characters "title" are centered at the center of the frame between ruled lines 1 and 2. Of course, it is possible to display it left-aligned or right-aligned as necessary. In one embodiment of the present invention, even such processing can be performed after specifying the ruled line range mode.

FIG. 1G shows a manner in which insertions and deletions are made in sentences within ruled lines. The illustrated case corresponds to a state in which the character ``di'' and then the character ``ni'' are to be deleted. In one embodiment of the present invention, even such insertion/deletion processing can be performed after specifying the ruled line range mode.

FIG. 1H shows a mode in which margins are set within the ruled lines 1 and 2 so that processing can be performed within the range of the margins 4 and 5, and the margins 4 and 5 can be easily changed. In one embodiment of the present invention, even such processing can be performed by setting margins in the ruled line range mode.

Note that in the present invention, it is not an essential requirement that each of the above functions be included, and it is also optional to include functions other than the above.
The technical scope of the present invention is determined by the description in the claims section.

Each function shown in the illustrated function control unit 17 is not provided for the first time by the present invention, so a detailed explanation of its operation will be omitted, but it may be considered as follows. That is, (1) the input conversion function 20 corresponds to the function of inputting enlarged characters and reduced characters as shown in FIGS. 1B and 1C.

(2) The kana-kanji conversion function 21 corresponds to the function of converting kana input into kanji input, as explained with reference to FIG. 1A.

(3) As explained with reference to FIG. 1D, the registration function 22 corresponds to the function of cutting out, for example, a rectangular area within a specified range and registering it for later use.

(7) Copying and/or moving and the associated line break function 29 cut out a text in the same way as shown in Figure 1D and create a copy in another position,
This corresponds to a function that automatically performs line breaks that occur when a line is moved to another position.

Now, in Figure 2, when we assume that the ruled line range mode is not set, the flip
Flop 13 is in a reset state. In this state, it is assumed that Japanese input is performed while performing kana-kanji conversion as shown in FIG. 1A, for example. In this case, first move the cursor to the input start position using the cursor control unit 9, then input "keisen" using the kana character keys, press the conversion key, and enter the kanji "ruled line". let During this time, cursor 3 will move to the kana characters ``ke'', ``i'', ``se'',
Each time you input "n", the cursor is shifted one character to the right in the X-axis direction, and when converted to the kanji "ruled line", the cursor is positioned one position to the right of the character "line". Ru. During this time, when the cursor reaches, for example, the right end of the display screen, it is automatically changed to a new line and positioned at the left end. In addition, in response to the input of the above-mentioned kana characters "ke", "i", etc., the screen control unit 12 sequentially sends " The character code is written as ``ke'' → ``kei'' → ``keise'' → ``keisen,'' and the character code ``ruled line'' is written as a result of conversion. Then, the display control section 10 periodically reads the contents of the screen code buffer 11 and displays them on the display 6.

Each function in the function control section 17 corresponds to the processing by the kana-kanji conversion function 21, and the range from the left end to the right end of the display screen of the display 6 is regarded as the processing range, and the processing is performed in the normal mode. You can think of it as processing.

When the ruled line range mode is designated by operating a key on the keyboard 7, the flip-flop 13 shown in FIG. 2 is placed in a set state. In this state, the left and right end detection sections
The contents of the X, Y buffer 15Y and the screen code buffer 11 are read out, and the X coordinate positions of the ruled lines 1 and 2 written on the buffer 11 are preset to the left end buffer 16L and right end buffer 16R. In this state, for example, using the kana-kanji conversion function 21, Japanese input is performed as shown in FIG. 1A.

During this input, the coordinate position of the cursor is set in the X buffer 15X and Y buffer 15Y, and the contents of the respective buffers 15X and 15Y are updated in accordance with the movement of the cursor. The left and right end detection unit 14 shown in FIG. When the content is reached, the content of the Y buffer 15Y is +1 and the X buffer 15X is added to the cursor control unit 9.
An instruction is given to set the value obtained by adding 1 to the contents of the left end buffer 16L. Kana-kanji conversion function 2
The processing by 1 itself is the same as in the normal mode, and conversion processing is performed, but the display screen of display 6 and the screen code buffer 1
The processing above 1 is performed within the frame of ruled lines 1 and 2, as shown in FIG. 1A.

Each of the functions in the function control section 17 also changes the range in which the cursor moves, that is, the left end buffer 16L and the right end buffer 16R, in a manner corresponding to the processing by the kana-kanji conversion function 21 in the ruled line range mode. The area within the area is regarded as the processing area, and processing is performed in the ruled line area mode.

As explained with reference to FIG.
This is done by specifying the coordinate position. That is, the coordinate position of margin 4 shown in FIG. 1H is set in the left margin register 19L, and the coordinate position of margin 5 is set in the right margin register 19R.
These values are also notified to the left and right end detection section 14.

In a state where this margin is set, the left and right edge detection unit 14 detects the contents of the X buffer 15X,
The contents of Y buffer 15Y, the contents of left margin register 19L, and the contents of right margin register 19R.
The range of movement of the cursor is restricted based on the content of the cursor.

As described above, according to the present invention, by instructing the ruled line range mode, cursor control is performed while automatically checking the position of the ruled line and the set margin position. For this reason, for example, editing processing for creating slips and charts can be efficiently executed, and the functionality of the Japanese input device can be further improved.
