BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creation device having a function of executing editing processes such as deleting and inserting characters, moving a cursor, etc. in a created document in response to key input instructions.

2. Description of the Related Art Conventionally, in Japanese word processors, editing processes such as deleting, inserting, backing characters, and moving a cursor in a created document are performed by operating special keys provided on a keyboard. Specifically, when the delete key is operated, each character is deleted from the character indicated by the cursor forward (toward the end of the sentence). On the other hand, when the backward key is operated, each character is deleted backwards (towards the front of the sentence) from the character indicated by the cursor.

Furthermore, when the insert key is operated, a space is inserted before the character indicated by the cursor, or a blank line is inserted before the line indicated by the cursor. The cursor is moved vertically and horizontally by operating the forward/backward and left/right cursor keys.

[0004] Various editing processes can be executed by operating such dedicated keys, but normally one key operation processes one character at a time. Therefore, for example, in order to delete 20 characters, it is necessary to operate the delete key 20 times. In order to eliminate such drawbacks, there are devices having a so-called auto-repeat function. The auto-repeat function is a function that, when a key is held down, continuously executes the function corresponding to the key. For example, if you keep pressing the delete key, the character string will be deleted consecutively starting from the character indicated by the cursor. When the delete key is released, the deletion process ends. This eliminates the need to perform key operations for each character when performing editing operations such as deleting multiple characters or inserting multiple spaces, eliminating the hassle of key operations. .

[0005]

[Problem to be Solved by the Invention] In a device that executes editing processing such as deleting, inserting, backing up characters, and moving a cursor by operating each dedicated key, by using an auto-repeat function, it is possible to You can perform continuous editing processing. However, the processing speed of the auto-repeat function is too fast, and for example, in the case of deletion processing, characters may be deleted more than necessary. In other words, it is difficult to determine when to keep pressing a key and release it at the required position. Furthermore, although there are devices that perform processing such as deletion on a line-by-line basis, processing on a character-by-character basis is not possible.

An object of the present invention is to enable continuous character-by-character processing with a small number of key operations in editing processing such as deleting, inserting, backing up characters, and moving the cursor. An object of the present invention is to provide a document creation device that can improve the efficiency of document creation.

[0007]

[Means for Solving the Problems] The present invention provides for deleting characters,
In a document creation device having a function of performing editing processing such as insertion and cursor movement, an input means for instructing the content of editing processing and the number of consecutive times when specified editing processing is to be executed continuously; Editing that executes the contents of the editing process specified by the input means for the specified number of consecutive times by referring to the memory means for storing the contents of the editing process specified by the input means and the data on the number of consecutive times, and the memory contents of the memory means, respectively. This is a device having processing execution means.

[0008]

According to the present invention, when the contents of the editing process and the number of consecutive times are instructed by the input means, the contents of the editing process and the number of consecutive times data are stored in the memory means. The editing processing execution means refers to the contents stored in the memory means and executes the instructed contents a number of consecutive times. Specifically, for example, when character deletion processing is instructed, character strings corresponding to the number of consecutive times instructed are deleted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram for explaining the conceptual configuration of a document creation device according to an embodiment of the present invention. Further, FIG. 2 is a block diagram showing the main parts of the document creation device of the same embodiment.

As shown in FIG. 2, this device includes a central processing unit (CPU) 1 that executes document creation processing, various editing processing, and various control processing, a keyboard 2 and input control section 3 that are input devices, and a display device. The printer 6 includes a display 4 and a display control section 5, and a printer 6 and a print control section 7, which are printing devices.

Furthermore, this device includes a ROM (read only memory) 8 that stores programs for the CPU 1 to execute various processes, a kana-kanji dictionary (ROM) 9 for kana-kanji conversion processing, and a document buffer memory ( RAM) 10
has.

In such a document creation device, the functional configuration according to the present invention includes an editing work control section 11, an editing processing section 12, a character string temporary saving memory 13, as shown in FIG.
A memory 14 for storing instruction contents of editing processing and consecutive number data, a screen data memory 15, and a screen display unit 1
Consists of 6.

The editing work control section 11 executes the control necessary for the editing processing of the present invention. The editing processing section 12 includes a deletion processing section 12a, a deletion restoration section 12b, an insertion processing section 12c, and a cursor movement processing section 12d, and executes editing processing such as deletion, insertion, backtracking, and cursor movement. The character string temporary save memory 13 is a memory that temporarily stores character strings in the deletion range during deletion processing and backing-up processing. The screen data memory 15 stores the edited document information and outputs it to the screen display section 16. The screen data memory 15 and the screen display section 16 are components corresponding to the display control section 5 and display 4 shown in FIG. The editing work control section 11 and the editing processing section 12 are components corresponding to the CPU 1 shown in FIG.

The keyboard 2 includes, in addition to various character and symbol keys, special keys 2a to 2k necessary for the editing process of the present invention. However, the numeric keypad 2e corresponds to normal numeric keys. Key input signals from the keyboard 2 are decoded by the input control section 3 and input to the editing work control section 11 . Next, the operation of this embodiment will be explained.

First, when a character string is input from the keyboard 2 (step S1 in FIG. 3) and a kana-kanji conversion process is instructed, the CPU 1 refers to the kana-kanji dictionary 9 and executes the kana-kanji conversion process ( Step S2). Document data created by the CPU 1 is expanded into a document buffer memory 10. The display control unit 5 displays the document data developed in the document buffer memory 10 on the screen of the display 4 under the control of the CPU 1 (step S3). The print control unit 7 stores the document buffer memory 1 under the control of the CPU 1.
The document data expanded to 0 is printed by the printer 6.

Here, when a key input for instructing editing processing is made from the keyboard 2 for the created document (YES in step S4), the editing work control unit 11 performs editing processing of the instructed content. Execute. If the content of the editing process is not continuous mode (NO in step S5)
), the editing processing unit 12 executes conventional editing processing (step S11). That is, each time a dedicated key is operated, editing processing is performed for each character. For example, when the delete key 2a is operated, a process is executed in which characters in the document indicated by the cursor are deleted one character at a time forward (toward the end of the text).

On the other hand, when the continuous mode is instructed (YES in step S5), the input control unit 3 stores in the memory 14 the instruction contents corresponding to the keys 2f to 2i related to editing processing in the continuous mode of the keyboard 2. It is stored in area 14b (step S6). Furthermore, the input control unit 3 stores data indicative of the number of consecutive inputs to be made in the storage area 14a of the memory 14 by operating the numeric keypad 2e of the keyboard 2 (YES in step S7, S8). The consecutive number of times data is data corresponding to the number of characters according to the number of operations of the keys 2f to 2i.

Specifically, for example, when the continuous deletion key 2f is operated, the contents of the instruction for continuous deletion processing are stored in the storage area 14b of the memory 14. Furthermore, when the number of characters to be deleted is 20, the numerical value "20" input by operating the numeric keypad 2e is stored in the storage area 14a of the memory 14.

After this, when the selection execution key 2j is operated (YES in step S9), the editing work control section 11 performs the following operations.
The memory 14 is accessed, the instruction contents stored in the storage area 14b are referred to, and instructions are given to the editing processing section 12 (step S10). In the editing processing section 12, for example, the deletion processing section 12a is activated according to the instruction content (YES in step S12 in FIG. 4).

The editing work control section 11 accesses the memory 14, refers to the consecutive number data stored in the storage area 14a, and instructs the editing processing section 12 (step S1).
3). The deletion processing unit 12a temporarily stores and saves a consecutive number of character strings from the character in the document indicated by the cursor in the memory 13 (step S14). The deletion processing unit 12a executes a process of deleting a consecutive number of characters (in this case, 20 characters) from the character in the document indicated by the cursor forward (in the direction of the latter part of the sentence) (step S15).
).

If the deletion return key 2k is operated after the deletion process by operating the continuous deletion key 2f and before any key input operation such as the selection execution key 2j is executed (step S16
YES), the deletion restoration unit 12b is activated and performs deletion restoration processing. That is, each time the deletion return key 2k is operated, one character is restored (step S17). Deletion restoration section 12
b reads the character to be restored from the memory 13 and restores it to the document. The deletion restoration unit 12b modifies the contents of the memory 13 every time a character is restored (step S18).
). That is, the restored character is deleted from the character string temporarily saved in the memory 13.

When the continuous reverse key 2h is operated (
(YES in step S19), the deletion processing unit 12a executes backward processing for deleting character strings the same number of consecutive times as in the continuous deletion processing (steps S20 to S22). Continuous backward processing is the opposite of continuous deletion processing, and is processing in which characters are deleted consecutively from the character indicated by the cursor (in the direction toward the front of the sentence) a number of times. When the deletion restoration key 2k is operated after this continuous backward processing, the deletion restoration section 12b is activated and performs the deletion restoration processing as described above.

Furthermore, when the continuous insertion key 2g is operated (YES in step S23), the insertion processing section 12c is activated and inserts a space in front of the character indicated by the cursor.
Execute the process of inserting the number of consecutive times (step S2
4-S25). In this case, for example, when a line feed key (not shown) on the keyboard 2 is operated, a blank line may be inserted before the line indicated by the cursor.

Furthermore, when the cursor movement key 2d is operated (YES in step S26), the cursor movement processing unit 12d is activated and executes processing to move the cursor in the up/down and left/right directions by the number of consecutive times. (Steps S27-S28). Here, cursor movement key 2d
consists of four cursor keys corresponding to the up/down and left/right directions.

In this way, when performing editing processing such as deletion, insertion, backtracking, and cursor movement, the continuous mode can be specified using, for example, a dedicated key, and the number of continuous operations can be specified using, for example, a numeric keypad. Editing processing can be performed continuously. Specifically, for example, 2
If a continuous deletion process for 0 characters is instructed, deletion processes for 20 characters starting from the character specified by the cursor can be performed consecutively.

That is, the editing process can be performed continuously for the number of consecutive times by simply operating the keys to specify the content of the editing process and the number of consecutive times. Therefore, conventionally, for example, 2
In order to delete 0 characters, it was necessary to operate the delete key 20 times, but with the present invention, this can be accomplished with at least two key operations. In addition, in contrast to the method that uses the auto-repeat function, the present invention executes editing processing for the required number of characters according to the number of consecutive times specified in advance, resulting in inconvenient situations such as deleting more characters than necessary. can be prevented.

[0028]

Effects of the Invention As described in detail above, according to the present invention, editing processing such as character deletion, insertion, backward movement, and cursor movement can be performed character by character simply by key operations that specify the content of editing processing and the number of consecutive editing operations. It can be done continuously and continuously. Therefore, especially when performing editing processing for a plurality of characters, it can be performed with a small number of key operations, and as a result, the efficiency of key input operations when creating a document can be improved.
