Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a Japanese input device, particularly a Japanese input device that displays ruled lines by assigning character codes corresponding to the ruled lines. The present invention relates to a Japanese language input device that is capable of displaying ruled lines and automatically generates displays corresponding to intersections, branching points, and inflection points of the ruled lines in the process of displaying the ruled lines.

In a Japanese input device, a word input in kana characters is converted into kanji by operating an exchange key, and a kanji-like sentence is input. When displaying ruled lines in such a Japanese input device, character codes are assigned in accordance with a display pattern of N strokes.
It is desirable that the display patterns at intersections of ruled lines, branch points, and busy points be in the form of +, T, Lfi, etc., but it is extremely troublesome for the operator to instruct character codes corresponding to these display patterns one by one. It is.

Furthermore, it is desirable to consider the types of ruled lines, such as dotted lines, thin lines, and thick lines, but considering these types of lines makes the operator's instructions even more complicated.

The present invention aims to resolve the above points,
The purpose is to automatically generate a desired display pattern by simply specifying the type of line using a character key. Therefore, the Japanese input device of the present invention is compatible with a keyboard/board, a cursor control unit that controls the cursor position by key operations on the keyboard/board, a display, and a display mode displayed on the display. A Japanese input device 1t is provided with a screen code buffer in which code information is stored, and inputs Japanese sentences while converting kana character strings input by key operations on the keyboard into kanji characters, The ruled lines JII are created by associating character codes with the ruled line patterns displayed on the display screen of the display.
't or based on the movement direction of the ruled line to be erased and the cursor position, the screen code is extracted from the dictionary memory as instructed by the current character code read from the buffer and the character key on the keyboard. A ruled line pattern generation unit is provided which generates a new character =- from the character code read from the screen code buffer according to the line type information of the abstract, and the character code generated by the ruled line pattern generation unit is converted into the screen code. -KLft is characterized by displaying ruled lines by storing it on a buffer. This will be explained below with reference to the drawings.

FIG. 1 is an explanatory diagram illustrating how a ruled line display pattern is generated in the present invention, and FIG. 2 shows the configuration of an embodiment of the present invention.

Figure 1 (B) is a diagram explaining which direction the ruled line extends from the coordinate point (g, y).
A ruled line pattern/number code is assigned as shown in the figure.
, r3J is given. For example, Figure 1 (C)
As shown in the figure, ruled lines with thin horizontal lines are
Figure (b) As shown, it is expressed as a four-digit number r 0022 J. Then, when the cursor is set at the coordinate point (g, y) and the lower ruled line instruction key is pressed while the ruled line pattern shown in FIG. 1(C) is displayed, the first
Figure 1 ((I
The four-digit number 1'-0222J indicated by IK is automatically displayed, and the ruled line pattern shown in FIG. 1 (n) is displayed.

In addition, in FIG. 1 (B), the number to be inserted in the column shown in FIG. 1 (B) and the line type of the ruled line are changed. , the number "2" is assigned to correspond to thin lines, the number r3J is assigned to correspond to thick lines, and the number "0" is assigned to correspond to ruled line deletion (or non-existence).

In the case of the present invention, by utilizing the characteristics of the Japanese input device,
The operator is prompted to input, using the character keys, whether to select a line type with a deviation of h. For example, when the operator presses the conversion key after inputting ``Tensen'' using the character keys, the dictionary memory is indexed and the input ``Tensen'' is input.
A line type numerical value "1" is determined corresponding to the line type. For example, when the lower ruled line instruction key is pressed as described above for a position where a ruled line pattern as shown in FIG. is given, and the 4-digit number corresponding to the ruled line pattern is r 0221
You can think of it as J.

Note that the four-digit number corresponding to the ruled line pattern ν can also be used as it is as the character code corresponding to the ruled line lsK. However, in general, the above 4-digit number is often used as another character code, and in practice, the above 4-digit number is converted to a character code that is unlikely to be used for other purposes.
It is used after

FIG. 2 shows the configuration of an embodiment of the present invention. In the figure, 1 is a display, 2 is a keyboard, 3 is a keyboard control unit, and 4 is a cursor control unit that indicates the position of the cursor. 5#i screen code buffer in which codes corresponding to the display on the display screen of display 1 are stored; 6 is a display control unit which stores screen codes;
A turtle reads out the contents of the buffer 5 and displays them on the display IK.

Further, in the 7-cane character code read register, the coordinate position of the cursor is supplied to the screen code buffer 5 by the cursor control unit 4, and the character code written on the coordinate position is set. 8 is a character code pair pattern number code index table, for example, the contents of the character code reading register are r2038
:J When searched by the illustrated search mechanism 9-0, the pattern number code r 1120
When J is read out and a reverse K/(turn φ number ring → -t "1120" is given) and searched by the illustrated search mechanism 9-IK, the character code r 2C38J will be displayed one after another. The index table constitutes a code converter, and the pattern number code is shown in Figure 1 (D
), (G)K The character code is the screen code, (This is the code stored in the sofa 5.) The correspondence between these two codes is written in advance on the index table 8. Stored as a busy pair.

Reference numeral 10 denotes a ruled line direction detecting section, which detects either the top, bottom, left or right as shown in FIG. 1(4) when the ruled line direction is given by the number of keys on the keyboard. Reference numeral 11 is a pattern number code read register in which the pattern number code read from the index table 8 is set. Reference numeral 12 denotes a line type code register in which the Sal type numerical value of the ruled line shown in FIG. 1(6) is written. 13
is also a line type code register, and a numerical value ".0" is preset to correspond to when erasing ruled lines. Reference numeral 14 denotes a pattern synthesizing section, which inputs the contents of the register 11, that is, the pattern number code corresponding to the coordinate position (gay) indicated by the cursor, the detection direction by the ruled line direction detecting section 10, and the register 12 when creating ruled lines. In other words, based on the line type value of the new ruled line to be drawn, a new pattern/number code to be given to the coordinate position is synthetically generated. 15d new pattern,
Number, code, and register, in which the generated code is set.

Further, 16 and 17 each represent an OR logic section, and 18 to 22 each represent an AND logic section.

Furthermore, 23 represents a kana-kanji conversion unit, 24 a dictionary memory, 25 a character buffer into which input codes entered manually using character keys are set, and 26 a dictionary memory search mechanism. Furthermore, 27 is a line type numerical index table, 28 is a search mechanism for the line type numerical index table, and 29=
210 each represents an AND circuit.

Now suppose that the line type code register 124C has a value of "3".
” is set, character code r2c38J is stored at the coordinate position indicated by the cursor, and the character code is r2c38J in the pattern number code.
1120 J.

That is, it is assumed that, at the coordinate position, there is a pattern that is similar to a dotted ruled line going up and down and a thin ruled line going leftward.

Under this condition, the screen code buffer 5 is accessed and the character code ``2038J'' is read into the register 7.Then, in order to display a thick ruled line that is currently moving towards the right, press the key to create a ruled line that is moving towards the right. When the instruction is given by
1120 J Read to register 11. On the other hand, the ruled line direction detection unit 10 detects the right direction. register 12
The content “3” is supplied to the pattern synthesis unit 14 via the AND logic unit 21. As a result, the pattern synthesis unit 14 adds the rightward line type value "3" to the register 11C) content r1120JK, generates a new pattern number code [1123J, and stores it in register 1.
Set to 5.

As a result, the illustrated search machine 1$19-1 will be activated, and the new pattern - number meeting code r 1128
The index table 8 is indexed based on J. and,
The character code “#” corresponding to the code r 1123 J
``Hayashi'' is read out and passed through the AND logic section 19 to screen code ノ (written on the sofa 5.

That is, the character code "# material" is written at the address position corresponding to the coordinate position of the cursor. This result is displayed on the display 1 by the function of the display control section 6. That is, a ruled line pattern having dotted lines in the vertical direction, thin lines in the left direction, and thick lines in the right direction is displayed on the display 1.

In order to instruct the line type of a newly created ruled line, it is sufficient to set the contents of the register 12 to correspond to the instruction.This point will be described later. Also, if the ruled line is not displayed at the coordinate position specified by the cursor,
Index: When pull 8 is indexed, "0000J" is read out as the pattern number code.

Furthermore, in order to erase a line segment heading in a desired direction from a ruled line pattern that has already been displayed, the user instructs the user to erase it using a key. In this case as well, the pattern Φ number code at the coordinate position is read out from the register 11K, the ruled line direction is detected by the detection section 10, and the contents of the register 13, that is, the numerical value "0" are synthesized into a pattern via the AND logic section 22. You will be led to section 14. As a result, a line type value "0" is given to the corresponding ruled line direction and set in the register 15 as a new pattern number code.

Then, the character code corresponding to the new pattern number code is read from the index table 8, and the screen code
Written to buffer 5. That is, a ruled line pattern in which the line segments in the corresponding direction are deleted is displayed on the display 1. Then, the cursor is shifted one character up, down, left, or right.

Creation and deletion of ruled lines are performed as described above, but in the case of the present invention, the operator can manually specify the type of ruled line using kana/kanji conversion section 23. As explained with reference to FIG. 1 (6), for example, the AS class value "1" is assigned to the dotted line, and "Tensen" is used as the calling name. In addition, line type value ``2'' is assigned to correspond to thin lines, and the call name ``2'' is assigned.
#1 Sosen” is used. Similarly, in response to the absence or deletion of a ruled line, a line type value of "0" is assigned, and "Keshigomu" is used as the calling name.

Then, in the dictionary memory 24, the readings are "Tensen", "
Dotted line [
.--.The code corresponding to the square or thin line "□" is stored. On the other hand, in the line extreme value numerical index table 27, the dotted line "...
..." code and the thin line "□" code, line type numerical values "lJ,, r2J, ..." are stored.

If the operator wishes to draw a new ruled line with a thin line, use the kana character key to select "Hasosen".
After inputting , press the convert key. This sets the character buffer 25K ``disabled'' and activates the search mechanism 26. That is, the dictionary memory 24 is indexed by reading, and the code "..." corresponding to "Hasosen" is indexed.
...'' is read out. Dictionary memo! Of course, 324 includes the code for the kanji ``thin line'' that corresponds to ``Hasosen'' (4).
include. The nine results read from the dictionary memory 24 are written into the screen code buffer 5 and displayed on the display 1, and are also supplied to the line type numerical index table 27. The table 27 is then indexed by the search mechanism 28. The operator observes the pattern displayed on the display 1, and when the desired pattern rJ appears, presses the stroke number key on the keyboard. Type number “2”
is set in register 12.

In this way, the contents of the register 12 can be specified using the character keys, and any line type can be specified.

As explained above, according to the present invention, it is possible to easily specify the line type of ruled lines using the functions of the Japanese input device, and it is also possible to create or delete ruled line patterns with a simple operation. , and it is possible to automatically extract patterns corresponding to intersections, branching points, and bending points of ruled lines.
