Description

[Detailed Description of the Invention] (1) Technical Field of the Invention The present invention relates to a character processing device such as a word processor that edits characters input in association with a cursor position on the display. Allows you to set the cursor between characters and between lines,
The present invention relates to a character processing device capable of setting characters and line spacing cursors, which facilitates processing such as inserting character strings, and improves operability.

(2) Background of the technology With the spread of office automation (OA), character processing devices such as word processors have come into widespread use.

Character processing devices are designed to display characters entered from a keyboard on a display while allowing editing such as creation and correction of sentences, thereby saving labor in administrative processing for document creation. The most important thing is to provide functions that are easy to operate and have great flexibility.

(3) Prior Art and Problems In character processing devices, a cursor is used to display the position of the next character to be manipulated on the display screen. The cursor is displayed as an underline or a reverse display with the brightness of the dot pattern reversed, but conventionally, the cursor position has been set in a pair for each character position to be displayed on the display screen. It was made to correspond to 1. That is, for example, if the display has a display capacity of 40 characters x 22 lines (880 characters), there will be 880 cursor positions. For normal character input, the cursor moves one character to the right for each character input, and if you want to move the cursor to the desired position separately from character input, you can use the keyboard The cursor was moved by pressing an upward, downward, leftward, or rightward cursor movement key provided above.

As mentioned above, since the cursor position corresponds only to each character position, for example, when it becomes necessary to correct a sentence that has already been input and insert a character, first place the cursor at the position where the cursor should be inserted. Next, press the "Insert" key to switch to insert mode, key in the character string to be inserted, and then press the "Execute" key to execute the specified insertion process. I was trying to get it to work. If you enter characters immediately after setting the cursor without pressing the "insert" key,
The character processing device recognizes the replacement mode and performs processing to replace the character corresponding to the cursor position with the newly input character.

According to the conventional method described above, in order to distinguish between replacement and insertion, in the case of insertion, it is necessary to press the "insert" key in advance and then press the "execute" key afterwards, making the operation complicated. Become. This way of thinking about processing does not make the machine suit the convenience of humans, but rather imposes a burden on the operator based on the convenience of the machine, especially in the case of character processing devices used for labor-saving purposes. Not desirable.
It goes without saying that it is desirable for the operator to be able to operate the system in a conversational and natural manner. Additionally, according to the conventional method, it is easy to forget to press the "Execute" key later, especially when the string to be inserted becomes long or when insertions become nested, such as when inserting characters while inputting them. The disadvantage was that it was easy to cause operational errors.

(4) Purpose of the Invention The present invention aims to solve the above-mentioned problems, and makes it unnecessary to press the "insert" key and "execute" key when inserting characters, making it possible to insert characters in an interactive manner similar to character replacement operations. The object of the present invention is to provide a character processing device that is easy to use and can be processed through natural operations. Also, in particular, it allows you to set the cursor between lines,
The purpose is to improve the operability of character editing regarding line spacing.

(5) Structure of the Invention In order to achieve the above object, the character processing device of the present invention capable of setting character and line spacing cursors includes a keyboard and a cursor control device that controls the position of the cursor by key operations on the keyboard. In the character processing device, the character processing device includes a character processing unit, a display, and a character editing processing unit that edits characters inputted by key operations on the keyboard in association with a cursor position. A cursor display area is provided between a character frame in which each character in the area is displayed and character frames adjacent to the character frame vertically and horizontally, and the cursor control unit
The character editing processing unit includes a means for positioning and controlling a cursor in the cursor display area by operating a predetermined key on the keyboard, and the character editing processing unit is configured to display a cursor display between the character frames adjacent to the left and right of the cursor. means for performing character editing processing between characters in adjacent character frames in response to character input when the cursor is positioned in a cursor display area between vertically adjacent character frames; The present invention is characterized in that it includes means for performing character editing processing on the line spacing between adjacent character frames in response to character input when there is a character input.

(6) Embodiments of the invention Examples of the invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram of the configuration of a display area according to the present invention, and FIG. 2 is an explanatory diagram of a cursor display state. In the figure, 1
2 represents a character frame, 2 represents a cursor display area, and 3 represents a cursor display.

For example, assume that the display of the character processing device according to the present invention displays characters in m columns×n rows. The display area is configured as shown in FIG. Conventionally, the cursor was associated only with each character frame 1, but in the present invention, each character is also associated with each of the cursor display areas 2 between the characters. Therefore, there are four types of cursor display states, for example as shown in FIG.
Figure A shows a case where the cursor is associated with a character, and Figures B to C in the second figure show a case where the cursor is associated between character strings or between lines. However, the present invention does not necessarily have to include all of the above four types, and the state D shown in FIG. 2 may not be set.

The position at which the cursor is set on the display area is determined by the value held in the cursor register controlled by the cursor control section, as will be described later. For example, suppose a cursor register indicates the cursor position by X and Y coordinates on the display area, where x is any integer from 1 to m, and y is any integer from 1 to n. i) Cursor display 3 shown in Figure 2A is due to X=x, Y=y (ii) Cursor display 3 shown in Figure 2B is due to X=x-0.5, Y=y , (iii) The cursor display 3 shown in Figure 2C is based on X=x, Y=y-0.5. (iv) The cursor display shown in Figure 2D is as follows: Each position is represented by 0.5.

3 to 6 show character editing processing modes in the cursor states shown in FIGS. 2A to 2D, respectively.

For example, assume that the cursor 3 is displayed at position (i, j) in the state shown in FIG. 3A. In this state, if the character "D" is entered by key, the result will be as shown in Figure 3B, the character "B" will be overwritten with the character "D", and the character string "ABC" will be changed to the character string "ABC". ADC”. The cursor display 3 is moved to the right by one character,
It is updated to indicate the position (i+1, j) from the position (i, j). Therefore, the next time a character is keyed in, the character entered on the character "C" will be overwritten. The editing process for the above characters is
This is similar to conventional character replacement processing. However, whereas conventional operations for character insertion processing required, for example, setting the cursor, pressing the "insert" key, inputting characters, and pressing the "execute" key, the operations are now extremely simplified as follows. It turns out.

For example, as shown in FIG. 4A, the cursor display 3 is located between the letters "B" and "C"
0.5, j). In this state,
For example, if the letter "D" is entered,
As shown in Figure 4B, the letter “B” and the letter “C”
The letter "D" is inserted between. Note that the character string after the letter "C" is shifted to the right one character at a time. Cursor display 3
is updated to indicate the position of (i+1.5,j). If the character input key is then pressed,
Next, it will be inserted between the character "D" and the character "C". In this way, the operations for inserting characters can be performed by setting the cursor and inputting characters, as in the case of character replacement. Such operations are intuitively understandable.

For example, as shown in FIG. 5A, the cursor display 3 points to (i, j-
0.5). In this state, for example, if the letter "D" is entered on the key, the fifth
As shown in Figure B, the character string “LMN” from line j onwards,
"XYZ" is shifted downward one line at a time, and the letter "D" is inserted below the letter "B".
In addition, in the part other than the letter "D" in the new j line,
For example, Null Code (00) is inserted. Further, the cursor display 3 is updated to indicate, for example, the position (i+1, j), but depending on the specifications, it may be made to indicate the position (i, j+0.5), for example.
This line spacing operation can be used, especially when adding furigana later, by specifying a half-line break if necessary, so that furigana can be added without causing characters to shift to the next line. This makes the input easier.

For example, assume that the cursor display 3 is at the position (i-0.5, j-0.5) as shown in FIG. 6A. In this state, if the character "D" is entered by key, as shown in Figure 6B, the character strings "LMN" and "XYZ" from line j onwards will be changed to 1 as in the case shown in Figure 5. The characters are shifted downward line by line, and the letter 'D' is inserted below the letter 'B'. The cursor display 3 is updated to indicate the position of (i+0.5, j), for example.

FIG. 7 shows an explanatory diagram of a cursor movement mode when a cursor movement key is pressed.

The cursor movement keys are used to set the cursor at a desired position regardless of character input. As before, the cursor movement keys include up,
There are four types of movement: downward, leftward, and rightward movement. For example, when the cursor movement key to the right is pressed, as shown in FIG. caused to move in the direction. That is, the X coordinate of the cursor position is increased by 0.5. The same applies when the leftward cursor movement key is pressed, and the X coordinate is controlled to decrease by 0.5 sequentially so that the cursor display 3 moves to the left.

When the downward cursor movement key is pressed, the cursor display 3 is sequentially moved downward as shown in FIG. 7B. That is, the X coordinate of the cursor position is increased by 0.5. The same applies when the upward cursor movement key is pressed.

Therefore, by pressing the cursor movement key, the operator can set the cursor at an arbitrary position and select any of the states A to D shown in FIG. 2.

FIG. 8 shows the configuration of an embodiment of the present invention. In the figure,
4 is a display, 5 is a display control section, 6 is a screen code buffer, 7 is a character editing processing section, 8 is an external storage device, 9 is a printer, 10 is a cursor control section, 11 and 12 are cursor registers, 13
and 14 is an update circuit, 15 is a keyboard control unit, 16 is a keyboard, 17 is a character input key,
18 represents a cursor movement key.

The display 4 displays characters input on the screen, for example, in a dot pattern, and also displays a cursor at a predetermined position. The display control section 5 scans the screen code buffer 6 and controls the display of characters and the like on the display 4 based on the code information.

The character editing processing unit 7 includes a keyboard control unit 15
The key-in information transferred from
Write the character code of the editing result to buffer 6.
It also performs processing to output the results to the printer 9 as necessary.

The cursor control unit 10 includes a cursor register 1
1 and 12, and also operates update circuits 13 and 14 to control the cursor. Key·
The board control unit 15 manages the keyboard 16 and controls character input keys 17 and cursor movement keys 1.
The key-in information caused by pressing 8 is transferred to the character editing processing section 7, etc.

For example, the character editing processing unit 7 uses the character input key 1 in response to an interrupt from the keyboard control unit 15.
7 is detected, the character editing processing unit 7
refers to the contents of cursor registers 11 and 12 and determines which state the cursor is in among the states A to D shown in FIG. Then, based on the determination result, processing is performed to edit the characters as shown in FIGS. 3 to 6.

When the cursor movement key 18 is pressed,
In response to a notification from the keyboard control section 15, the cursor control section 10 operates the update circuit 13 or 14 depending on the type of cursor movement key 18 that was pressed, and updates the contents of the X cursor register 11 or cursor register 12. Update so that the value changes by 0.5. To simplify the explanation, the above explanation assumes that when the cursor is positioned between characters, the coordinate value has a fraction of 0.5, but in reality it is processed as a binary bit value, for example. Needless to say.

FIG. 9 shows a partial configuration of another embodiment of the present invention. In the figure, codes 10 to 12, 15 to 18
corresponds to FIG. 8, 19 is the mode register, 2
0 represents the cursor mode setting key.

In order to indicate which state the cursor is in, for example from A to D in FIG. Y
Each of the cursor registers 12 is configured to take an integer value as before, and a separate mode register 1
9 may be provided, and the cursor state may be distinguished depending on the contents of the mode register 19. The contents of the mode register 19 are set by, for example, a cursor mode setting key 20 provided on the keyboard 16. For example,
When the value of the cursor register 11 is x and the value of the Y cursor register 12 is y, if you press the "CUR2" key of the cursor mode setting keys 20, the "CUR2" mode is set in the mode register 19. The information shown is stored, and the cursor moves to Figure 2B.
The state will be as shown. In this state, when the character input key 17 is subsequently pressed, the character editing processing section 7 refers to the mode register 19, determines the cursor state, and edits the character as shown in FIG.

Although the present invention is realized as described above, the following functions may be added in order to improve operability.

FIG. 10 shows an explanatory diagram of the latest change area display. In the figure, 21 and 22 represent latest change area display marks, and 23 represents a deletion position display mark. For example, for a change process by replacing or inserting a series of characters, the area to be changed is
As shown in FIG. 0A, it is displayed surrounded by latest change area display marks 21 and 22. If the operator checks the changes and discovers that an error has been made in the key operation, for example, by pressing the "invalid" key (not shown), the area surrounded by the latest change area display marks 21 and 22 can be displayed. The changed content is invalidated, and it is possible to return to the pre-changed state that was saved in advance. Also, for deletion processing of a series of characters, the deleted position is
This is indicated by the deletion position display mark 23 as shown in FIG. 10B. If the operator discovers that there is an error in the deletion process, he or she can restore the original state by pressing the "invalid" key. Latest change area display mark 21, 2 above
2 and the deletion position display mark 23 are extremely useful for confirming changes and deletions. As a result of the confirmation, if there are no errors, the latest change area display can be canceled by starting another process such as pressing a cursor movement key, or by pressing a "cancel" key (not shown). , any changes or deletions will be valid.

FIG. 11 shows an explanatory diagram of the target setting process. In the figure, 24 represents an operation target area, and 25 and 25' represent target setting cursor movement keys. Traditionally, when deleting a series of characters, for example, you would set the cursor, press the "Delete" key, move the cursor,
This required an operation such as pressing the "execute" key. Also, if you want to move a series of characters to another location, you can set the cursor, press the "Move" key, move the cursor, press the "Execute" key,
It required operations such as setting the cursor and pressing the "execute" key. However, in general, it is more conversational and natural to specify the processing target first and then instruct the processing action, rather than to first instruct the processing action and then to instruct the processing target. It can be said that it is easy to operate. In order to realize the latter operation, as shown in FIG.
Settings can be made by pressing 5. That is, for example, when the target setting cursor movement key 25 is pressed to the right as shown in FIG. 11A, the operation target area 24 is expanded one character at a time to the right, and as shown in FIG. 11B. , when the leftward target setting cursor movement key 25' is pressed, the operation target area 24 is reduced by one character.

As described above, by allowing the operation target area 24 to be set in advance, it is possible to instruct the processing operation later. For example, if you want to delete a series of characters, you just need to set the cursor, move the target cursor, and press the "Delete" key. Also, if you want to move the series of characters to another location, This can be done by setting the cursor, moving the target setting cursor, pressing the "delete" key, setting the cursor, (moving the target setting cursor), and pressing the "move" key.

In this operation, the target string is stored in the save area. Specify the destination with , (can be omitted). If omitted, the cursor status will be either CUR2 or CUR4, but the movement behavior will differ depending on the status.
In the case of CUR2, the contents of the save area are overwritten from CUR1, and in the case of CUR2, the contents of the save area are
2, and at CUR3/CUR4, the contents of the save area can be inserted into rows. If you perform this operation, the target character string can be moved and replaced with the contents of the save area.

For copying, simply press the "copy" key. In this case, the contents are stored in the save area, leaving the target string intact.

If the functions explained using FIGS. 10 and 11 are added to the character processing device of the present invention, together with the function that allows editing by setting a cursor between characters, an even easier-to-use character processing device will be realized. It becomes possible.

(7) Effects of the Invention As explained above, according to the present invention, it is possible to reduce the number of key operations required for character editing, and also to enable unified operation, promoting labor saving in document creation. can do. In particular, since character operations on line spacing are also possible, character editing can be performed in detail.
