Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for displaying Hangul characters, and more particularly to a display device that simultaneously displays Hangul combination characters and the alphabets forming the combination characters.

All Hangul characters are literary symbols that can be written exactly as they are pronounced, and they also have the character of hieroglyphs that can be combined in a two-dimensional manner according to certain rules.

BACKGROUND ART Conventionally, it is known to input each character of Hangul characters from an input device such as a keyboard or a tape reader, and to print the characters as a combination.

This will be explained below using the drawings.

FIG. 1 is a diagram illustrating the state of inputted characters of Hangul characters and the combination of characters displayed on a display device.

First, the consonant "〓" is input, but since "〓" alone cannot distinguish whether it is a front consonant or a back consonant, nothing is displayed on the display screen.

Next, by inputting the vertical vowel "〓",
It is determined that the consonant "〓" input earlier is a front consonant, and the front consonant "〓" is displayed. Next, when the consonant "〓" is input, the vowel "〓" is displayed, but it is not clear whether the consonant "〓" just input is a back consonant or a front consonant of the next letter. Therefore, when the consonant "〓" is input next,
The consonant "〓" input earlier is determined to be a consonant after the consonant, and the combination character "〓" is displayed.

Next, by inputting the vowel "〓", it can be determined that the consonant "〓" input earlier is the consonant in front of the second character, and thus the combination character "〓" of the first character can be determined. is completed, and the front consonant "〓" is displayed.

Further, the vowel "〓" is displayed as a combination character "〓" by inputting the next character "〓".

However, this has the disadvantage that inexperienced operators often make mistakes because they do not know what the character that has just been input is.

Therefore, the present invention attempts to solve the above-mentioned problem by displaying the character combination and also displaying the character that has just been input.

FIG. 2 is a block diagram showing an outline of the present invention. In FIG. 2, 1 is a keyboard device for inputting each character of the Hangul alphabet or other characters, functions, numbers, etc., 2 is an input device such as a tape reader, mark reader, card reader, etc., 3 is a transmission line, and 4 is a an input buffer for temporarily storing data codes input from the aforementioned input device, etc.; 5;
is a pattern memory that stores each character pattern to be displayed, and generally uses ROM.

Reference numeral 6 denotes a display memory that stores the pattern read out from the pattern memory 5 based on the input data code while displaying the pattern, and also refers to the previously input character and the currently input character. The combination pattern memory 6a stores patterns as combination characters, and the current pattern memory 6b reads patterns corresponding to the currently input characters from the pattern memory 5 and stores them. 7 is a display device consisting of a combination character display section 7a and a character display section 7b;
The display screen of the same display section may be divided and used, or each may be an independent display section.

Reference numeral 8 denotes a control device that reads a corresponding pattern from the pattern memory 5 based on the input character code, edits the combination pattern based on the next input code, and performs control until it is displayed on the display device 7. It is.

Next, the operation of the present invention will be explained with reference to FIGS. 3 and 4. In addition, in this example, to simplify the explanation, "〓", "〓", which are double front consonants,
The five letters "〓", "〓", "〓" and the four vertical diphthongs "〓", "〓", "〓", "〓" are used as double front consonants and vertical diphthongs respectively. An example will be explained in which the keyboard is equipped with the jimo characters , and a space method is used in which a space is inserted between characters.

First, each time a character is input, it is determined whether it is a consonant or not, and until a consonant is input, it is skipped and invalidated, or a Hangul character other than a consonant comes in the first character. This is impossible, so it is treated as an error.

When a consonant appears at the first character, the pattern corresponding to this consonant is read out from the pattern memory 5, set in the current pattern memory 6b, and displayed on the character display section 7b as shown in FIG. 4A.

Next, it is determined what the character entered as the second character is, and if it is other than a vowel, it is treated as an error, and if it is a horizontal vowel, the contents of the current pattern memory 6b are transferred to the combination pattern memory 6a. , reads out the pattern corresponding to the vowel that has just been inputted from the pattern memory 5, and sets it in the current pattern memory 6b. Therefore, consonants are displayed on the combination character display section 7a, and vowels are displayed on the character display section 7b, as shown in FIG. 4B.

Next, input the third character, and combine the contents of the current pattern memory 6b into the pattern memory 6.
Combined with the contents of a, the combination pattern memory 6a
At the same time, the pattern corresponding to the character just inputted is set in the current pattern memory 6b.

Thereafter, each time a character is input, the contents of the current pattern memory 6b and the combination pattern memory 6a are combined.
and the contents of the combination pattern memory 6a.
At the same time, the pattern corresponding to the input character is set in the current pattern memory.

Therefore, the pattern set in the combination character display section 7a is displayed on the combination character display section 7a, and the pattern set in the current pattern memory 6b is displayed on the character capital display section 7b. When the third character is input, it is determined whether it is a space (SP) and the third character is input.
If the first character is a space, it is identified as a Hangul character composed of a front consonant + a lateral vowel (C + V _H ), so it is displayed on the combination character display section 7a as shown in Figure 3A. , the character display section 7b becomes blank.

If the third character inputted is not a space, it is further determined whether or not it is a vertical vowel. If it is not a vertical vowel, it is further determined whether it is a consonant, and if it is a consonant, it is displayed on the display device 7 as shown in FIG. 4C. Then, the fourth character is input and it is determined whether it is a space or not. If it is determined to be a space, that character is a front consonant + horizontal vowel + rear consonant (C +
Since it is specified that it is a Hangul character consisting of V _H +C), it is displayed on the combination character display section 7a as shown in FIG. 3B.

If the fourth character is not a space, it is determined whether it is a consonant or not, and if it is not a double consonant, it is considered an error. If it is a double consonant, the display device 7 displays a message as shown in FIG. 4D. is displayed. and,
Furthermore, input the 5th character and judge whether it is a space or not. If the 5th character is not a space, it will be considered an error. If it is a space, that character will be a front consonant + horizontal vowel + rear consonant + rear consonant. Consonant (C+V _H +C+C)
Since it is specified that it is a Hangul character consisting of , the combination character display section 7a displays it as shown in FIG. 3C.

Next, when the third character inputted is a vertical vowel, the display device 7 displays it as shown in FIG. 4E. Then, if you input the fourth character and it is a space, it specifies that the Hangul character is composed of front consonant + horizontal vowel + vertical vowel (C + V _H + V _V ). The combination character display section 7a displays the characters as shown in FIG. 3D.

Further, if the fourth character inputted is not a space, it is further determined whether or not it is a consonant, and if it is not a consonant, this is an error. If the fourth character is a consonant, it is displayed on the display device 7 as shown in FIG.

Next, input the fifth character and determine whether it is a space. If it is a space, the character is a front consonant + horizontal vowel + vertical vowel + rear consonant (C + V
Since the Hangul characters are identified as _H + V _V + C), they are displayed on the combination character display section 7a as shown in FIG. 3E.

Further, if the character inputted as the fifth character is not a space, it is further determined whether the character is a consonant, and if it is a consonant, the combination character display section 7
A is displayed as shown in FIG.

Next, enter the 6th character and determine whether it is a space. If it is not a space, it will be an error. If it is a space, the character is a front consonant + horizontal vowel + vertical vowel + rear consonant + Back consonant (C+V _H +V _V +
Since it is specified that it is a Hangul character consisting of C + C), the third character is displayed in the combination character display section 7a.
It will be displayed as shown in the figure.

Further, when the character input as the second character is a vertical vowel, it is displayed on the display device 7 as shown in FIG. Next, enter the third character and judge whether it is a space or not. If it is a space, that character is a front consonant + vertical vowel (C + V
Since it is specified that it is a Hangul character consisting of _V ), it is displayed on the combination character display section 7a as shown in FIG. 3G.

If the character input as the third character is not a space, it is further determined whether it is a consonant or not,
If it is not a consonant, it will be an error. That is, in Hangul, it is impossible for a vertical vowel to be followed by a horizontal vowel, or even a vertical vowel.

If the character is a consonant, it is recognized as a consonant after the consonant, and is displayed on the display device 7 as shown in FIG. Next, input the fourth character and determine whether it is a space. If it is a space, that character is a front consonant + vertical vowel + back consonant (C
Since it is specified that the Hangul characters are composed of +V _V +C), they are displayed on the combination character display section 7a as shown in FIG. 3C.

Furthermore, if the fourth character entered is not a space, it is further determined whether or not it is a consonant. If it is not a consonant, it is determined as an error, and if it is a consonant, the display device 7 displays the fourth character. It is displayed as shown in Figure 4.

Next, input the fifth character and judge whether it is a space or not. If it is a space, that character is a front consonant + vertical vowel + consonant + consonant (C + V _V
+C+C) is identified as a Hangul character, so it is displayed on the combination character display section 7a as shown in FIG. 3.

Note that although the method for displaying Hangul characters using the space method has been described above, the display method for Hangul characters using the non-space method can be similarly displayed by just slightly changing the determination method.

In other words, when using the non-space method, there are no spaces between characters, so when a vowel is input, the character immediately before it is determined to be a front consonant, and other consonants are determined to be rear consonants. This allows you to distinguish between the previous and subsequent characters. For example, when inputting C+V+C+C, Figure 5 shows how to distinguish whether the last consonant input is the second consonant of the character just input or the front consonant of the next character input. , FIG. 6, and FIG. 7.

FIG. 5 is a block diagram showing an example of the non-space method of the present invention, in which the same parts are given the same numbers.

In FIG. 5, 6c is a pattern buffer 1, 6d that reads the pattern corresponding to the input character from the pattern memory 5 and temporarily stores it.
is pattern buffer 2 to which the contents of pattern buffer 1 are transferred before the next character is input, and when the next character is input, the contents set in pattern buffer 2 are transferred to pattern buffer 2. , a new composite pattern is generated based on the contents set in the combination pattern memory 6a, and is set in the combination pattern memory 6a.

7c is a first character display section for displaying the contents of the pattern buffer 1, and 7d is a second character display section for displaying the contents of the pattern buffer 2.

Next, the operation will be explained.

First, the text is skipped until the first consonant appears and is invalidated, or an error occurs. When a consonant is input as the first character, the pattern corresponding to that consonant is read out from the pattern memory 5, set in pattern buffer 1, and displayed on the first character display section as shown in Figure 7A. , the contents set in pattern buffer 1 are transferred to pattern buffer 2, and the second character is input into pattern buffer 1, which is now empty.

Therefore, the contents set in pattern buffer 2 are displayed on the second character display section 7c, and the contents set in pattern buffer 1 are displayed on the second character display section 7d as shown in FIG. 7B. be done.

Thereafter, the same operation is performed every time one character is input.

In this explanation, the pattern is stored in the pattern buffer 1 and pattern buffer 2, but the character code is also stored in the display device 7.
It goes without saying that it may be converted into a pattern when displayed on the .

When the second character is input, it is determined what it is, and if it is a horizontal vowel, the pattern buffer 2
The contents set in and the combination pattern memory 6
The content set in a (initially blank) is synthesized, the combined pattern is set again in the combination pattern memory 6a, and the pattern buffers are replaced in the same manner as described above, and the empty pattern buffer is Enter the third character in 1.

Therefore, the display device 7 displays as shown in FIG. 7C. If the character entered as the third character is a consonant, preparations are made to input the next character, and the fourth character is input into the empty pattern buffer 1.

If the fourth character is a vowel, the display device 7 will display the seventh character.
Since one character is completed with the front consonant + vowel (C + V) displayed as shown in Figure D and displayed in the combination character display section 7a as shown in Figure 6A, the first character display section 7c and Second character display section 7d
The operator is notified of the completion of one character by erasing only the display.

In addition, various methods can be used to notify the completion of one character, such as changing the brightness of the display surface, switching to blinking, or providing another display.

Also, when the character inputted as the fourth character is a consonant, the display device 7 displays as shown in FIG.
In order to determine whether it is the front consonant of the next character, the fifth character is input, and if the fifth character input is a vowel, the display device 7 will display a message as shown in Figure 7. The consonant entered as the fourth character is determined to be the front consonant of the next character.

Therefore, the characters that have been input now are front consonant + horizontal vowel + back consonant (C + V
It can be identified that it is a Hangul character consisting of _H + C).

Also, when the fifth character is a consonant, the display device 7 displays as shown in Figure 7G, and the consonant input as the fourth character is the second consonant of the character that has just been input. It turns out that.

However, since this second consonant is still set in the pattern buffer 2, it is synthesized with the content set in the combination pattern memory 6a and set in the combination pattern memory 6a again. The combination character display section 7a shows the sixth
It is displayed as shown in Figure C.

Therefore, the second character display section 7d becomes empty as shown in FIG. 7H.

As described in detail above, according to the present invention, in a display device that displays a combination of Hangul characters, there is provided a determination circuit that determines the sequentially input characters, and a determination circuit that determines the characters input sequentially to form combination characters. at least one buffer memory for storing a pattern; a combination character memory for storing sequentially input characters as a combination character when the combination becomes possible; a combination character display section for displaying the contents of the combination character memory as a pattern; a character display section that is provided corresponding to the buffer memory and is capable of displaying at least one character character that displays the contents of the buffer memory as a pattern;
It is possible to provide a display device for Hangul characters that is capable of displaying characters that cannot yet be combined.

This allows the operator to visually confirm the type of character that cannot be combined that has just been input, thereby increasing the input speed and reducing input errors.
