Abstract

PURPOSE:To quickly perform the fast forward and the rewind of a screen and then to ensure the smooth shift to a drawing corresponding to each processing by setting a variable in response to the display screen corresponding to each processing and deciding the processing to be carried out next and a display screen based on the key information and the set variable. CONSTITUTION:The value of a variable a is decided in a step S24 in accordance with the type of an input key. That is, the variable a is set at 0 when both CODE and UNDO keys are inputted at one time. Then the processing under execution is canceled and the initial screen is reset. When only the UNDO key is inputted, the variable a is set at 1 and the precedent screen is reset. When a downward arrow key is pushed, the variable a is set at 2 with alpha equal to 1 and then at 4 with alpha larger than 1 respectively. Thus a screen preceding by two is shown. When an upward arrow key is pushed, the variable a is set at 3 with beta equal to 1 to show preceding screen and then at 5 with beta larger than 1 respectively. Then a screen preceding by an extent equal to beta is shown.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing device such as an English word processor or an electronic typewriter.

[0002]

2. Description of the Related Art In a conventional word processor, for example, when a tutorial (operation education program) is loaded and executed, the program is once loaded from an external storage device into a memory in the main body and then executed. Has been done. In such programs, usually 1
One process corresponds to the screen, the next screen corresponds to the next process, the previous screen corresponds to the preprocess, and so on.

[0003]

However, in the above-mentioned conventional example, since the processing and the screen correspond one-to-one,
It had the following drawbacks. (1) In one process, the next screen corresponds to the next process and the previous screen corresponds to the preprocess in one process, but in the other process, the next screen corresponds to the next process and the previous screen corresponds to the preprocess. In another process, the next screen corresponds to the next process, and the previous screen corresponds to the previous process, so that the required specifications may be different. However, even in such a case, the previous screen is uniformly associated with the preprocessing and the next screen is associated with the next processing. (2) Also, during the process, even if you want to know the overall image of the process and try to fast forward the screen, each process is executed for each screen (for example, text data is set in the text area and displayed). (Until it is displayed on the container)
Sometimes fast-forward cannot be performed.

The present invention has been made in view of the above-mentioned conventional example, and an object of the present invention is to provide a document processing apparatus capable of quickly moving from the current processing to the most appropriate processing by key input.

[0005]

In order to achieve the above object, the document processing apparatus of the present invention has the following configuration.
That is, a document processing device that performs various processes according to key information input based on the items displayed on the screen, and a key input means for inputting key information and a variable corresponding to each display screen are set. Setting means, a key information input from the key input means, and a screen control means for determining a process to be executed next and a display screen according to the variable.

[0006]

With the above structure, a variable is set corresponding to the display screen corresponding to each process, and the process and the display to be executed next according to the key information input by the key input means and the set variable are set. Operates to determine the screen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a schematic configuration of a word processor according to an embodiment of the present invention, and FIG. 2 is an external perspective view thereof.

In FIG. 1, a keyboard 1 is operated by an operator to input document data, various function instructions and data. A printer 2 prints out edited document data, stored document data, and the like. Reference numeral 3 is a display device (display) for displaying document data and a message to an operator, such as a liquid crystal display or a C display.
It is composed of RT and the like. A floppy disk drive (external storage device) 4 stores document data and various programs. 6 is a ROM that stores the control program represented by the flowcharts shown in FIGS. 3 and 4, and 7 is used as a work area of the MPU 5.
It is a RAM that temporarily stores various data.

In this embodiment, first, a floppy disk is set in the floppy disk drive 4, and the MPU 5 executes a program of the floppy disk (in this embodiment, for example, by instructing to load the program by key input from the keyboard 1). RA) tutorial
Load on M7. The free space prepared as the text data storage area of the word processor on the RAM 7 is limited to a size smaller than that during normal use, and the tutorial program is loaded. Then, after the loading is completed, this program is executed immediately.

FIG. 3 is a flowchart showing the processing of the main routine of this tutorial itself.

First, in step S1, the counter is numbered 0.
(No. = 0) is substituted, and in step S2 of
The start address of the process corresponding to the number is calculated, and in step S3, the program branches to the calculated address.

After jumping in this way, a subroutine in which a series of processes is described is executed from the addresses corresponding to the respective numbers, and the processes corresponding to the numbers (here, the operation by inputting each key is explained. Message is displayed and it is actually operated) is executed. This processing will be described later in detail with reference to the flowchart of FIG.

After this subroutine is executed and returns, the screen is switched according to the value of a as shown in steps S4 to S9.

This processing will be described in detail with reference to the flowcharts of FIGS. 3 and 4 and the screen switching examples of FIGS. 5-1 and 5-2.

Now, it is assumed that the display 3 is displaying a menu screen 501 shown in FIG. Here, when "1" is input from the keyboard 1 and a menu item is selected, the description of the format setting is selected, and the screen display 502 shown in FIG. 5 is displayed. Then, with this screen 502 displayed,
When the "↓" key on the keyboard 1 is pressed, the next screen 50
3 is displayed. However, when the screen display 505 of the explanation shown by 503 is unnecessary, the keyboard 1 is pressed by 503.
By pressing the “↓” key of, the screen display can be switched to the screen 506.

Next, with this screen 503 displayed, the code key (CODE) of the keyboard 1 and "3"
When the and keys are pressed at the same time, a format input box is displayed, and when the key 1 of the keyboard 1 is input on the screen 504 in this state, a page format setting screen 505 is displayed, where the paper size, header, and footer are set. The location information of is input. This input box 50
After the display of 4, even if the “↓” key is pressed, the page format setting screen 505 is displayed. This screen 505
When the “↑” key of the keyboard 1 is pressed while is displayed, the screen returns to the previous screen 503.

Normally, the explanation of the setting of this format is as follows: Screen 501-Screen 502-Screen 503-
The process proceeds from screen 504 to screen 505 to screen 506 to screen 507 to screen 508 to explain the page format and margin and tab settings. But,
If you want to skip the description of page format settings and move to the description of margins and tabs while 503 is displayed, press the "↓" key while screen 503 is displayed. This makes it possible to skip the description of the page format setting and proceed to the margin / tab setting explanation processing screen 506.

If it is desired to omit the margin tab setting description on the display screen 506, the user can press the "↓" key to proceed to the screen 509 of 2) Explanation of font size and font change.

This process will be described with reference to the flow charts of FIGS. 3 and 4. When the screen 503 of FIG. 5 is displayed, the process of FIG. 4 is started and step S of FIG.
From 21, the process proceeds to step S22. Here, the variable a is set to “99” (a number other than 0 to 5), the variable α is set to “2”, and the variable β is set to “1”. In step S23, waiting for a key on the keyboard 1 to be pressed,
When the key is input, the process proceeds to step S24, and the value of the variable a is determined according to the type of the input key.

That is, when the [CODE] key and the [UNDO] key are simultaneously input, the variable a "0" is set. As a result, the process currently being executed is canceled and the initial screen is displayed (step S10 in FIG. 3). In addition, [UN
When the [DO] key is input alone, "1" is set in the variable a.
Set. As a result, in step S11 of FIG.
The screen returns to the previous screen 502. When the "↓" key is pressed, a = 2 when the value of α is "1" and the next screen is displayed (step S12), and when α> 1, a = 4. In this case, since α = 2, the process proceeds to screen display two screens ahead (screen 506 in FIG. 5) (step S14).

When the "↑" key is pressed, the previous screen is displayed with a = 3 when the value of β is "1" (step S13), and when β> 1, a = 5. Then, the screen before the value of β is displayed (step S15). It should be noted that here, in the case of the "↓" and "↑" key inputs, whether the values of α and β are 1 or more is differentiated depending on the processing α = 1, β.
This is because it may be acceptable to keep = 1.

Next, in step S25, it is determined whether or not a numerical value is set in the variable a, and the value of the variable a is "0".
When it is between "5" and "5", the process returns to the main routine, and the screen switching process according to the value of a is executed. Step S26
Then, it is checked whether the CODE key and the "3" key are pressed at the same time, and if so, the process proceeds to step S27, where 50
Display the format menu in step 4.

Next, in step S28, respective values (here, α = 1 and β = 1) are set in variables α and β, and
The key input is awaited again in S29. When the key is input, the process proceeds to step S30 and the same process as step S24 is performed.
Then, in step S31, the value of the variable a is checked, and if the value of a is between "0" and "5", the process returns to the main routine.

As described above, after each process is executed, it is possible to set an appropriate offset value for fast-forwarding and rewinding the screen, so that fast-forwarding and rewinding of the screen can be performed quickly, and further, respectively. You will be able to move smoothly to the screen corresponding to the processing of.

Although the present embodiment has been described in the case of a tutorial (educational software) that operates on a word processor, the present invention is not limited to this. For example, a help function (a main body function) that operates on a word processor. It can also be used to move between pages (displaying operations, key functions, etc.).

Further, in the present embodiment, the processing corresponding to the number of each screen is expanded on the time-series straight line (sequenced), and the offset value of the movement amount (positive or negative direction) on the straight line is processed. Although it has been described that each of them has a screen number, the connection of screen numbers can be configured in an annular shape, and the offset value can be set to the right rotation direction or the left rotation direction.

Furthermore, the present invention is applied not only to a one-dimensional array such as a number line and an annular shape, but also to an array processing having a hierarchical structure,
Not only the offset within the same layer, but also the same layer, movement to another aggregate, and offset amount to another layer (up and down) may be possible to enable two-dimensional movement.

The present invention may be applied to a system composed of a plurality of devices or an apparatus composed of a single device. It goes without saying that the present invention can also be applied to the case where it is achieved by supplying a program for implementing the present invention to a system or an apparatus.

As described above, according to this embodiment, the offset values of the jump destination and the return destination of the screen to be displayed next during each processing are arbitrarily set, and the screen is advanced or returned according to the offset value. You can As a result, it is possible to quickly move between the screens, and also to move quickly to a screen according to the current progress of the process even when the process advances or returns during the process.

[0031]

As described above, according to the present invention, it is possible to quickly move from the current processing to the most appropriate processing by key input.
