Abstract

PURPOSE:To facilitate the drawing of ruled lines by providing a ruled-line mode and operating a character input key which corresponds to the kind of ruled lines and cursor movement keys in combination in the ruled-line mode. CONSTITUTION:In ruled-line mode, a character input key 2 is pressed, the contents of a mode register 7 are referenced to retrieve a ruled-line correspondence table 10. Then, one of ruled-line pattern codes classified by the kinds of ruled lines which corresponds to the character input key 2 is stored in a screen code buffer 12, and one of ruled-line images classified by the kinds of ruled lines is stored and held in a ruled-line image storage part 16. With a cursor movement key 3, a cursor movement detection part 15 detects the cursor movement indication and then confirms that the mode register 7 indicates the ruled-line mode, thereby transferring the ruled-line pattern code stored in the storage part 16 to some location in the screen code buffer 12.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an Il line input/output control method, especially when creating sentences using ruled lines such as 9 tables and graphs by operating keys on a keyboard in a word processor, etc. In addition, in the same way as the conventional ``alphanumeric'' character, r hiragana'' (- character, etc.), it is possible to specify the ``ruled line'' mode. Character input key associated with type and cursor moving
This is a turtle related to a ruled line input/output control method that allows ruled lines to be easily created by operating in combination.

For example, in tools such as Tsudobusesa, which creates sentences by displaying characters entered by key-in on the keyboard on the display, the cursor that indicates the position of the next character to be operated on the display screen is controlled. Conventionally, even when inputting and displaying a ruled line, a normal character and lI! are input at the current cursor position. 1IIK You were supposed to enter one character at a time. Therefore, it takes an extremely long time to create ruled lines.

When creating ruled lines in the vertical direction in 41 or the intersection of ruled lines.

When inputting display such as refraction point 1 branch point, etc.

Key operations were cumbersome.

An object of the present invention is to solve the above-mentioned problems and to enable input for creating ruled lines to be performed simply and quickly. Therefore, the ruled line input/output control method of the present invention is
a keyboard, a cursor control unit that controls the cursor position through key operations on the keyboard, a cursor movement key that instructs the wrinkle cursor control unit to move the cursor left/right or up/down, and a display. The input/output device is equipped with a ruled line and -mode switch key for instructing a ruled line mode, as well as a ruled line correspondence table in which information to be matched is stored.

When a character entry key associated with one of the ruled line types according to the ruled line correspondence table is pressed in the ruled line mode, a ruled line image corresponding to that ruled line type is stored;
If the cursor movement direction is left or right, the memorized ruled line image will be displayed in the horizontal direction, and if the cursor movement direction is upward or downward, it will be displayed in the vertical direction. The screen is configured to display and create ruled lines on the display using the stored ruled line image.

It is characterized by the ability to perform input/output control for creating ruled lines. This will be explained below with reference to the drawings.

FIG. 1 is an explanatory diagram for explaining the configuration of an embodiment of the present invention, and FIG. 2 is an explanatory diagram for explaining processing in a ruled line connection conversion section.

FIG. 3 shows an explanatory diagram for explaining an embodiment of the present invention.

In the figure, 1 is a keyboard, 2 is a character input key, 25 is a cursor movement key, 4 is a ruled line mode switching key - 25 is a line connection change key, and 6 is a keyboard system**.

A register indicating what the power code is.

For example, a screen display section in which a screen identifier is stored.

Correspondence table 1 of which characters are displayed in correspondence with the character input key when typing 1 For example, Hiragana correspondence table 8゜Katakana correspondence table! It consists of an address section for the address section.

To switch the input mode above, the number of keys is the number of input characters KW.
It is necessary to assign multiple meanings to a single letter in a small number of cases, and this is done to indicate which of them is meant by i.9 For example, Hiragana tatami.

Katakana letters, ALFum (English capital letters) letters.

Hatake 1fa (moji lower case) mode etc. is red, and the present invention is
In order to input information for creating a ruled line, a ruled line II curve is created and applied. This switching to the ruled line layer is performed by pressing a ruled line switch key 4 provided on the keyboard 1 separately from the normal character entry key 2.

- For example, when character entry key 2 is pressed when typing hiragana, a hardware interrupt is generated via the key/card control unit 6, and the correspondence table address field of the 4-word register 7' is points to the beginning of the hiragana correspondence table 8, so the hiragana correspondence table 8 is searched, and the character pattern corresponding to the nine-character key -2 pressed above is found.
The code is fetched and transferred to the one-screen code buffer 12 at the position indicated by the current cursor. 11 cursor control companies.

The cursor indicating the position to be transferred is controlled, and the cursor address is updated so that the cursor position is shifted one position to the right after the code in the character pattern is transferred. l
The character pattern stored in the i-round food buffer 12;
The - code is read out by the 0 display control section 13 and displayed on the display screen of the display 14. In the case of Katakana Sade, the correspondence table address part of the 4-word register 7 points to the Katakana correspondence table 9, so the Katakana correspondence table 9 is similarly referred to and corresponds to the pressed character key 2. When a katakana character is displayed on the display 14, it becomes K.

When the cursor movement key 2 is pressed outside the ruled line mode, that is, in the hiragana mode or katakana mode, the cursor control unit 11 moves the cursor to the right depending on the type of the cursor movement key 3.

Control to move left, up, or down. In this case, a new character pattern is not displayed on the display 14, but the cursor display 0 position, such as under twin, indicating the position of the character to be operated primarily is changed and displayed.

Move cursor $-! I press down the button, O causes hardware interrupts to occur one after another while the operator presses the button.
The cursor movement OJ6ml is performed continuously according to the pressing time of the cursor movement key 3.

When attempting to create a ruled line, the operator presses the entry key 4. ? By pressing the - ruled line mode switching key 4, the ruled line mode is displayed in the mode display section of the %- register 7, and the ruled line correspondence table 1 is displayed in the correspondence table address section.
A starting address of 0 is set. Bait line correspondence table 10 companies each with letters - 2 and examples are thick lI, thin line, thick dotted line, thin i
It associates the thickness of lines such as dotted lines and the type of ruled line according to the type of line, and can be arbitrarily determined in advance, but in particular, the direction of the line, the intersection of lines, bending points, branch points, etc. Since conversion processing is performed as described later for the types, there is no need to set and maintain correspondence information between these types and the character entry key 2.

When character input key 2 is pressed in ruled line mode.

When a hardware interrupt occurs, the mode register 7 is referenced, and the ruled line correspondence table 10 pointed to by the correspondence table address field is searched. Then, the ruled line pattern code of the ruled line type corresponding to the character input mode -2 is stored in the screen code buffer 712.

It is displayed on the display 14, and its ruled line type O
The ruled line image is stored and held in the ruled line image storage section 16. In the case of Jin, the cursor control unit 11KsP is

1' indicates cursor 0 111w: +1-dopazza 12
If the cursor movement direction is upward or downward, the ruled line image is transferred to the inner O position, and then the vertical direction conversion unit 17 converts the ruled line image 9005.

The converted ruled line pattern . In addition, 900＠ in advance
I turned! When the cursor control section 11 line and cursor movement key 5 are pressed, the line pattern .

The cursor address is controlled so that the cursor moves in the instructed direction, but the operator presses the cursor movement key 3 as described above.

A software interrupt occurs at predetermined time intervals, and the cursor address is updated sequentially to create the above ruled line pattern.
The image I[of the code is also transferred to the code buffer 12 continuously. Therefore, move the carnol movement key 5 to 11.
When 1L is pressed, it becomes possible to display a ruled line of the required length in the direction of movement of the cursor, and a desired ruled line can be input.

The ruled line 7iI connection conversion key 5 is the middle side of the intersection between the ruled line and ** □
It is a key for connecting ruled lines such as break points, etc., and may also be used for converting kana characters to kanji characters, for example. Ruled* in ruled line mode
*When the continuation conversion key 5 is pressed.

In response to a notification from the keyboard control section 6, the ruled line connection conversion section 18 performs a ruled line connection process according to the conversion section function described below with reference to FIG.

The ruled line connection conversion unit 18' reads one character each on the top, bottom, left and right of the current cursor position from the tZ11W=z-dopad7A12. The pattern that Jin read.

Suppose that it becomes i as shown in FIG. 2 (1) OA@B@C,D. Figure 2 (related) As shown, pattern B and C.
Create a logical product of two @D that match each other.

Next, as shown in Figure 2 (1), the logical sum of the above logical products is -
)<! , the result is (AnB)U(BnC)U(CAD
) U (Dn people).

On the other hand, there is a pattern A in the same room as shown in Figure 2 (M) inside.
′, B″, C″, D″ are prepared, and as shown in Figure 2 (V), the fixed Pan people ′, B′, C′, D′ and A@
Create the product of B・C@D and 0w1m1. And Figure 2 (
vO As shown in the diagram, create a logical sum of these logical products. HiO connection Jl is (AnA')jJ(BnB'')jJ(Cn
C') U(DnD').

Next, as shown in Figure 2, if we create the logical sum of the result of pattern (1) and the pattern (vll O result), it should finally be displayed at the current cursor position as shown in Figure 2. A pattern of ruled/line connected parts is created.The ruled II connection converter 18 stores it at the current cursor position as eo.Generally, the display of a word processor is 1, for example, 14x14. Since dots are displayed as dots, the above logical product and logic mma are 0 for each dot.
If it is done with N10FF, it will be.

Next, one embodiment of the present invention will be described with reference to FIG.

(1) Assume that the input mode is "Hiragana" at first. As shown in FIG. 3(1), the current input mode is displayed on the display 14, for example, at the bottom right of the display field.
Then the IEK cursor is displayed at the current cursor position. Note that internally, the mode display section of the mode own register 7 shows the hiragana command.

The correspondence table address section points to Hiragana correspondence table 8.

(2) At this point, when the operator presses the ruled line top switch key 4, the display section of the mode register 7 shows the ruled line and points to the line/ruled line correspondence table 10 in the correspondence table address section.

131 Both display surfaces of the display 14 become K as shown in FIG. 5 (J), and the ruled line O input dark code.

When the operator presses the character input key 2 (for example, the number "1") that corresponds to the ruled line type at the stage where each ruled line is displayed, the ruled line 1 will be stored in the image screen. 1 will be.

(51 days ago, the display screen of the display 14 is shown in Figure S (
5) A ruled line for one character is displayed as shown. In normal input modes other than ruled line mode, the Kd cursor position moves one position to the right, but in ruled line mode, the cursor does not move. (6) Next, press the cursor movement key S (see Figure 5). 16) When ``move right'' (in the illustrated example) is pressed, while it is pressed,
Hardware interrupts occur at predetermined time intervals, and the cursor is successively moved one step at a time to the right. Then, according to the movement of the cursor, the above-mentioned heat lI#/&J is stored at the cursor position every time the cursor is moved, and a ruled line is displayed as a nine ruled line image.

(η Until you stop pressing cursor movement key 5.

Upper i! The body (6) is repeated until the display form becomes as shown in (7), for example.

(8) Next, when the downward movement cursor movement key 5 is pressed, the cursor address is updated every time an interrupt occurs, similar to the above heat N46), but the ruled line is moved along the cursor movement direction, that is, 90 It becomes ζ゛ displayed in a rotated form.

(9) Therefore, the display on the display 14 - the appearance Figure 3 19
) If the cursor movement key 5 for left movement is pressed, the only difference is the left/right direction from the above process (6).

The processing contents are the same.

The display screen of the display 14 will be as shown in Figure 5.

If the cursor movement key 5 for a-yu upward movement is pressed, the only difference from the above 4611181 is the up and down direction.

The processing contents are the same.

Qll The display screen of the display 14 becomes as shown in the third diagram.a4 Next, when the ruled line connection change dF-s is pressed.

The corners of the ruled line frame are formed by the process of the ruled line S*continuation conversion unit 18@, which has been explained using FIG.

OS The corners of the ruled line frame are displayed as shown in Figure 5, and the input mode automatically returns to the previous mode, hiragana mode.

All operators use cursor movement key 3.

Move the cursor to the next intersection.

(Iη Since the mode has returned to hiragana mode, the cursor position after the movement is displayed instead of two overlapping ruled lines.

Next, by pressing the ruled line mode switching key 4.

Set the input mode to ruled line shade.

By pressing the ruled line connection conversion key 5, a ;-ner of the ruled line is formed as in the process I above.

The corners of the ruled lines are jin and K, which are displayed as shown in Figure 3 (2).

(2) Similarly, the above processes a. to c! By repeating at, display 1 is displayed as shown in FIG. 3(2).
A rectangle is displayed on the display screen 4, and the desired ruled line is input.

As described above, according to the present invention, it is possible to input ruled lines easily and quickly, and it is also possible to easily process ruled line connections.
