Thus, when inputting the hyphen, optimal processing is automatically and selectively conducted depending on the input position and optimal hyphen input processing can be performed by simple operation of inputting the hyphen at a desired position.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus or a document processing method in which a hyphen is input into document data and the input document and the hyphen can be displayed on a display screen. The present invention relates to a document processing apparatus or a document processing method capable of easily creating a good-looking document while improving the operability of the document.

[0002]

2. Description of the Related Art Conventionally, when inputting document data from a keyboard or the like, a document processing apparatus such as a word processor or a typewriter capable of inputting a hyphen while switching the input mode between an insert mode and an overwrite mode as necessary has been developed. Proposed.

Here, the insertion mode is an input mode in which new document data is inserted in front of the input position of the document data (the position indicated by the normal cursor), and the overwrite mode is the input position of the document data. This is an input mode in which new data is overwritten on subsequent data.

Thus, when a hyphen is input by such a conventional document processing apparatus, when the input mode is the insertion mode, a hyphen is inserted in front of the input position of the document data, and the input mode is the overwrite mode. In some cases, a hyphen is input by overwriting the already existing document data existing at the input position of the document data.

[0005]

As for the hyphen input by the above-mentioned conventional document processing apparatus, when the input mode is the insertion mode, a new hyphen is input in front of the input position of the document data as described above. There is no problem in hyphen processing because it can be input.

However, when the input mode is the overwrite mode, a hyphen is entered at the document input position and over the already input document data, so that the original document data is changed. As a result, there is a problem that a misspelling occurs in the original document data.

To avoid such a problem, the input mode can be switched from the overwrite mode to the insertion mode by operating the input mode switching key. However, such a mode switching operation is extremely complicated. Further, such a mode switching operation needs to be performed every time a hyphen is input, and from this point of view, it is unavoidable that the operation is a complicated operation. Furthermore, if the number of times the input mode switching key is operated during hyphen input increases, there is a possibility that the key may be erroneously operated, and there is also a problem that the erroneous operation may destroy the document data. Therefore, it is better that the number of input mode switching key operations is as small as possible, and there is room for improvement in the operability of document creation when inputting a hyphen.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art, and has as its object to provide a document processing apparatus or a document processing method capable of improving the operability at the time of hyphen input. I do.

According to the first aspect of the present invention, there is provided an input means for inputting document data, and a hyphen in the document data input by the input means. A hyphen input means for inputting
In a document processing apparatus having display means for displaying an input document and a hyphen on a display screen, when a hyphen is input by the hyphen input means, from the beginning of the current line to a hyphen according to the input position of the hyphen. And a control means for selectively processing a process of moving the character string to the end of the previous line and a normal hyphen process for inputting a hyphen at the input position. According to the second aspect of the present invention, in the document processing method in which a hyphen is input in the input document data and the input document and the hyphen can be displayed on the display screen, When a hyphen is input to the displayed document while displaying the displayed document, the process of moving the character string from the beginning of the current line to the hyphen to the end of the previous line according to the input position of the hyphen And a normal hyphen process for inputting a hyphen at the input position.

[0010]

According to the present invention having the above-described structure, by inputting document data through the input means and operating the hyphen input means, the input document and hyphen can be displayed on the display screen of the display means. Then, according to the input position of the hyphen, a process of moving the character string from the beginning of the current line to the end of the hyphen to the end of the previous line and a normal hyphen process of inputting a hyphen at the input position are selectively processed. You.
By this, a simple operation of inputting a hyphen at a desired position in the displayed document causes the character string from the beginning of the current line to the hyphen to the end of the previous line to the already input document data. The optimum hyphen input processing can be automatically selected and performed by moving or inputting normal hyphen input processing for inputting a hyphen at the input position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. This embodiment relates to an English word processor having an automatic line feed function. FIG. 1 is a perspective view of the word processor 1 and FIG. 2 is a control block diagram of the word processor 1.

As shown in FIG. 1, a keyboard 3 is disposed at the front of the main body frame 2 of the word processor 1, and a liquid crystal display 30 capable of displaying characters and symbols is provided at the rear of the keyboard 3, as shown in FIG. It is rotatably provided at a position and a storage position (not shown). A printing mechanism PM that prints characters and the like on printing paper while reciprocating along the longitudinal direction of a platen (not shown) is provided behind the liquid crystal display 30.

The keyboard 3 includes character keys 10 including alphabet keys, numeric keys, and symbol keys, a space key 11, a return key 12, an overwrite key 13 for setting an overwrite mode, an insert key 14 for setting an insert mode, and a hyphen key. 15, other various function keys and the like are provided. Here, the character key 10 is mainly operated when creating document data, the space key 11 is pressed to input a space, the return key 12 is used to input a carriage return, It is pressed when executing various processes.

Further, the input mode is set to the mode of the key pressed either the overwrite key 13 or the insert key 14. The hyphen key 15 is depressed when inputting a hyphen H (see FIG. 5) in the overwriting mode or the insertion mode set as described above.

The liquid crystal display 30 is for displaying characters and the like input from various keys arranged on the keyboard 3, and can display these characters and the like over a plurality of lines. Further, the printing mechanism PM
It is of a configuration that performs desired printing on a printing paper mounted on the platen via a printing ribbon by a printing hammer while selecting a type on a daisy wheel mounted on a carriage that can reciprocate along the platen, Since the configuration of the printing mechanism PM is known, the description is omitted here.

Next, the overall configuration of the control system of the word processor 1 will be described with reference to FIG. The word processor 1 basically includes a keyboard 3, a display unit DM, and a control unit C. Each of the keyboards 3 and the display unit DM is connected to the control unit C via an input / output interface 32.

The display unit DM has an input / output interface 3
2, a display controller 31 and a liquid crystal display 30. Characters and the like are displayed on the liquid crystal display 30 via a display controller 31 driven and controlled by a control unit C described later.

The controller C comprises a CPU 33, an input / output interface 32, a ROM 40 and a RAM 50 connected to the CPU 33 via a bus 34 such as a data bus.

A ROM (read only memory) 40 stores various programs and the like.
The program memory 41 includes a hyphen processing program described later, a program for controlling the display unit DM in accordance with code data input from the keyboard 3, a program for editing document data, and various other types of data necessary for controlling the word processor. Program is stored.

RAM (Read / Write Memory) 50
A text memory 51 for storing document data input from the keyboard 3 or external storage means (not shown);
A line buffer 52 for temporarily storing the line at the current cursor position, and an overwrite /
An insert mode area 53 and an overwrite / insert mode save area 54 for temporarily storing the overwrite / insert mode are provided.

In the above configuration, when document data is input from the keyboard 3 or external storage means (not shown),
The CPU 33 refers to the overwrite / insert mode area 53 of the RAM 50 according to the document editing program stored in the program memory 41 of the ROM 40, and in the overwrite mode, overwrites the input data from the current cursor position. That is, the character string currently at that position will be lost. In the insertion mode, the input data is inserted at the current cursor position. That is,
The character string currently at that position will be sent later in order.

Next, hyphen processing control performed by the control unit C of the word processor 1 will be described with reference to the flowchart of FIG. Here, it is assumed that before this control is started, the document data stored in the text memory 51 or the newly input document data is displayed on the display 30 as shown in FIG. 4, for example. Also, in FIG. 4, the cursor 60 moves to the word (p
reparatory) at the fourth character (the position of the second p), and four or more blank spaces exist at the end of the previous line.

In this state, when the hyphen key 15 is input in step (hereinafter abbreviated as S; the same applies to other steps) 1, the CPU 33 executes the flowchart shown in FIG. . When the hyphen H is input, it is determined whether or not the document data from the beginning of the current line to the cursor 60 at the hyphen input position can move to the previous line including the hyphen H (S).
2).

That is, if the number of characters from the beginning of the current line to the hyphen H is smaller than the number of blank characters at the end of the previous line (S2: YES), the character string from the beginning of the current line to the hyphen H is moved to the end of the previous line. The character string from the head of the line to the hyphen H is moved to the end of the previous line. Otherwise (S2: NO), the character string from the beginning of the line to the hyphen H cannot be moved to the end of the previous line, so it is processed as a normal hyphen input (S3), and the process is terminated.

When moving to the previous line (S2: YES),
The data of the overwrite / insert mode stored in the current overwrite / insert mode area 53 is temporarily saved in the overwrite / insert mode save area 54 (S4) and stored.
Subsequently, the input mode is temporarily set to the insert mode by storing the insert mode in the overwrite / insert mode area 53 (S5).

In this state, the same processing as when the hyphen key 15 is pressed is performed. That is, a hyphen H is inserted just before the cursor position on the line buffer 52 (S6), and the character string from the beginning of the current line to the hyphen H is moved to the end of the previous line (see FIG. 5). Thereafter, the data saved in the overwrite / insert mode save area 54 is returned to the overwrite / insert mode area 53 (S7).

As a result, the input mode is returned to the overwriting mode or the insertion mode before the execution of the flowchart processing, and the processing is terminated.

As described in detail above, in the word processor 1 according to the present embodiment, when the hyphen H
The input mode (overwrite mode or insertion mode) set in the overwrite / insert mode area 53 of M50 is temporarily saved in the overwrite / insert mode save area 54, and after the save processing, the overwrite / insert mode area 53 is set.
The insertion mode is set forcibly and temporarily regardless of the input mode that was set to, so that the input mode is automatically switched to the insertion mode at the time of hyphen input, thereby complicating input. A hyphen input can be performed by a simple key operation without performing a mode switching operation.

Further, even when the input mode set in the overwrite / insert mode area 53 is the overwrite mode, the input mode is switched to the insert mode at the time of hyphen input, so that the misspelling of the document data is performed by careless key operation. This can completely eliminate the possibility that valuable document data will be destroyed due to the occurrence of a problem.

Further, the word processor 1 according to the present embodiment
Has an automatic line feed function that determines whether the character string from the beginning of the current line to the hyphen H can be moved to the end of the previous line, and if so, moves the character string to the end of the previous line. Accordingly, a document with an extremely good appearance can be created in combination with the automatic switching function of the input mode described above.

After the input process of the hyphen H, the input mode temporarily saved in the overwrite / insert mode save area 54 before the mode change is automatically returned to the overwrite / insert mode area 53. , Hyphen H
After the input processing, document data can be edited in the original input mode before the mode switching.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various improvements and modifications can be made without departing from the gist of the present invention.

[0033]

As is apparent from the above description,
According to the present invention, when a hyphen is input to a displayed document, a process of moving the character string from the beginning of the current line to the hyphen to the end of the previous line according to the input position of the hyphen; The normal hyphen processing of inputting a hyphen at the input position is selectively processed, so that a simple operation of inputting a hyphen at a desired position in the displayed document can be applied to the already input document data. On the other hand, the character string from the beginning of the current line to the hyphen is moved to the end of the previous line, or the normal hyphen input processing of inputting a hyphen at the input position is performed, so that the optimum hyphen input processing is automatically performed.
