Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to various information processing apparatuses including at least an input device and a display device, such as word processors, office computers, personal computers, data processors, and workstations.

In particular, the present invention relates to an information processing apparatus capable of superimposing graphic characters.

Length rice 1! Generally, in the various information processing devices described above, when two graphic characters are superimposed, a backspace control character is inserted between the two graphic characters, and this is superimposed during display and printing. .

In this case, these graphic characters are usually represented by codes, and the codes constitute the text. Therefore, in this case, at least three codes are required to realize one superimposed graphic character. Therefore, if there is a limit to the length of the text, this method naturally reduces the number of characters that can be input.

Also, when specifying overlapping graphic characters during editing, you must first enter the overlapping graphic character on the screen, enter the backspace control character for overlapping, and then enter the graphic character you want to overlap. Must be. This operation will be required at least three times.

Normally, when it comes to graphical characters that you want to overlap, it is easier to use shapes that modify letters, character strings, or shapes than to overlap between characters, and for that purpose, it is also necessary to be able to easily prepare overlapping shapes. .

There is also a method of overlapping one line to create overlapping characters. However, in that case, even if you want to create a superimposed character for just one character, you will have to spend an extra line to do so, requiring more code, and it is not effective on a narrow display screen.

Additionally, there are some printers in which the printer head moves backwards during printing and overprints, but this is time consuming and may cause the printing position to shift, so it is a method that should be avoided.

This invention was made in view of the above points, and when one graphic character is superimposed on another graphic character to form a single graphic character, two arbitrary graphic characters can be directly combined with a simple operation. The purpose is to make them superimposable.

In order to achieve the above object, the present invention provides an information processing system that includes at least an input device and a display device, and is capable of visually displaying characters or figures input from the input device on the display device. In the device, a data area for superimposition that can be registered is provided, and the registered superimposition font is called using the character code corresponding to this data area for superposition, and is displayed on the display device by superimposing it on any specified graphic character font. It is equipped with a means for displaying the information.

Next, the operation of this embodiment will be specifically explained with reference to the drawings from FIG. 3 onwards.

First, the overlapping process will be explained with reference to the flowchart of FIG.

Enter characters etc. using the input device 1 and display them on the display device 1.
7 and while creating/editing a document, if there is a graphic character that you want to superimpose on the editing screen that is displayed 1. For example, if this is "○", move the cursor under this "O". Specifies the superimposed graphic characters to be superimposed.

In the next step, when the 1 overlap key 107 is pressed, it is determined that the screen shown in FIG. 9(a) is displayed. If you select the number "1" for "Call" here.

The screen shown in Figure (b) will appear, and there are 1, 1, and 2 character candidates for superposition.
2, 3, 4, 5. ...is displayed.

Therefore, you can select a superimposed font from these candidates. For example, if you select "x" as the superimposed font and press number key 1, the selected superimposed font will be imported in the next step to import the superimposed font. Combined font "X"
is taken in, and the graphic characters "o" and "x" are superimposed to form one graphic character.

This process is shown in FIG. 4(c).

FIG. 4(a) shows the structure of the text stored in the text storage area 11, and the structure of the internal code is as follows.

Therefore, the structure of the text in which "O" is stored is, if the internal code ■ is the code for "O", the internal code for "X" is as shown in FIG. The text is edited by the text editing circuit 7 so that the internal code ■ for superimposition is placed between the internal codes ■ (immediately before the internal code ■), and is stored in the text storage area 11.

FIG. 4(c) shows the creation of a completed font by adding the internal code "x" of the internal code "■" to the internal code "■" of the instruction font "○" shown in FIG. 4(b).

Next, a method of registering a font to be superimposed in the superposition font area 8 will be explained with reference to FIG. 9 and other drawings.

First, when the superimposition key 107 on the keyboard of the input device 1 is pressed, the menu screen of FIG. 9(a) is displayed on the display screen.

If the number key "2" is pressed here, the superimposition character selection screen shown in FIG. 9(b) will appear. The numbers on this selection screen are
Supports character codes of overlay fonts. That is, "1" corresponds to "x", "2""○", and "3" corresponds to "=".

If you press number key 4 here, the character code corresponding to number key 4 will change the superimposed font in the superimposed font area to the rectangular area 22 shown in FIG. 9(c).
Call and display inside.

This screen is the superimposition character creation/change screen shown in FIG. 9(c).

When the up/down/left/right cursor movement keys 103 and the function keys 104 are pressed simultaneously on this screen, the cursor 23 moves as shown in the area 22 of FIG. 9(c), and a dot is added after the cursor 23 moves.

In addition, the cursor 23 is placed where a dot has already been added.
When the cursor movement key 103 and function key 104 are pressed, the addition of the dot is deleted.

In this way, dots are added or deleted at arbitrary positions within the area 22 to create or change superimposed characters.

When the execution key 105 is finally pressed after completing the work of creating and changing overlay characters, the font at that time is taken into the overlay font area 8 corresponding to the number key "4". Registration is now complete.

Also, existing character fonts can be registered as they are in the superimposition font area.

At that time, the editing screen in the text input state (hereinafter referred to as the "editing screen")
), place the cursor on the position of the graphic character you wish to register and press the 1 overlap key 107. And Figure 9 (
When displaying a) and pressing the copy number key “3”, the 9th
The screen shown in FIG. 3B becomes a selection screen for selecting where in the superposition font area 8 to import the font.

If the number key "5" is pressed here, the font of the existing character indicated by the cursor is imported into the overlapping font area corresponding to "5". This completes registration.

Here, the registered font for superimposition corresponds to a character code on the edited text, is managed by the character code, and the storage position of the font for superposition is recognized by the character code.

Next, the process of displaying superimposed graphic characters will be explained with reference to the flowchart of FIG.

The first step is to sequentially read the internal code of the text.

Then, the font indicated by this internal code is stored as display data.

Next, it is determined whether the read internal code is a superimposition code or not. If it is not a superposition code, proceed to the next step.

In this step, the display data storage address is updated every time one font is stored.

In the previous step, if it is an overlay code, the storage address of the font indicated by this overlay code will not be updated, and when the next internal code is read, it will be placed on top of the previous overlay font. The next font will be overwritten. When the display data is filled in this manner, the overlapping graphic characters are displayed in an overlapping manner.

Next, the printing process of overlapping graphic characters will be explained with reference to the flowchart of FIG.

In the same way as in the above display, internal codes are sequentially called from the editing text.

The next step is to store the font indicated by that code in the print buffer.

At this time, it is determined whether or not the superimposition internal code has been read.

If it is not an internal code for superposition, proceed to the next step,
The storage address of print data is updated for each font read.

If it is an internal code for superimposition in the previous step, the font storage address is not updated, and a new font indicated by the internal code next to this internal code for superposition is overwritten.

In this way, when the printing data is filled, it is printed, and the overlapping graphic characters are printed overlapping from the beginning.

Here, a case in which figures of different colors are superimposed will be explained by giving a concrete example.

There are overlapping fonts and existing fonts as shown in FIGS. 5(A) and 5(B), where (A) is registered as a font for overlapping, and FIGS. 5(A) and 5(B) are editing screens.

In FIG. 5(A), the graphic characters (A) are superimposed at the position of this cursor 21. At this time, in the edited text, as shown in FIG. 6, the internal code (A) is inserted immediately before the internal code (A).

Then, as shown in Fig. 5(B), the two graphic characters overlap to form the figure ``Sunflower.''

Here, it is assumed that a color can be specified for graphic characters.

Now, at the cursor position in Fig. 5(B), cursor 21
recognizes (a) in Figure 6.

If you press the color specification key 10, which determines one of the character attributes, the screen shown in Figure 10 will appear and the flower part of ``Sunflower'' will blink. At this time, if you specify the color yellow, the flower part of the ``sunflower'' (A) will be specified as yellow.

Then, (b) in Figure 6 is recognized, and the stem of the "sunflower" blinks. At this time, if you specify the color green, the stem part of the ``sunflower'' (A) will be specified as green.

When this is printed, a print as shown in FIG. 5(C) can be obtained.

In this way, with overlapping graphic characters, it is possible to specify several colors or similar attributes within one graphic character.

Next, we will explain how to delete overlapping characters.

First, at the cursor position in FIG. 5(B), the cursor 21
is aware of the internal code (a) in Figure 6. If the character deletion key 108 is pressed here, a screen like that shown in FIG. 10 appears (however, there is no color specification display at the bottom right), and the flower part of "Sunflower" blinks.

If the character deletion key is further pressed here, the internal code (A) in FIG. 6 will be deleted. In other words, the "sunflower" flower disappears and becomes as shown in FIG. 5(A).

When deleting a normal character, the display is deleted in one operation without blinking. When overlapping characters are erased in this way, the overlapping graphic characters are erased first.

As described above, by implementing the present invention, since characters for superimposition can be recognized using only character codes, editing text data can be shortened.

Furthermore, it is possible to specify several types of colors within one graphic character. Then, several types of graphic characters can be layered to be visible as one graphic character. Moreover, since the data of superimposed characters of the same color are already overlapped when printing, they are printed, so that the data overlaps reliably and the quality is good.

Furthermore, it is possible to easily delete only the graphic characters that overlap the original graphic characters.

As explained above, according to the present invention, any two graphic characters can be directly superimposed and displayed as one graphic character with a simple operation.
