Abstract

PURPOSE:To form no pattern of an unfinished or erroneous character when there is an error in designating a character constituting element code by checking the propriety of the character constituting element code included in a character code. CONSTITUTION:The character code decided to be a Hankul character code is decomposed to a section code, a consonant code, a vowel code and a patchim code. Whether the consonant code is one within the defined range of S01-S13 or not the checked, if it is within this range, it is advanced to the check of the vowel code to check whether it is within the range of S01-S15 or not. When the vowel code is within said range, whether the patchim code is within the range of S00-S1F and one except S10, S11, S13 or not is checked and when it is understood that it is defined, the Hankul code is decided to be correct to advance to a Hankul character pattern forming processing.

Description

DETAILED DESCRIPTION OF THE INVENTION Summary of the Invention A configurable character is a character created by a combination of multiple character components. When a character code is given, the character code is decomposed into the codes of the character constituent elements constituting the character, and the given character pattern is generated by combining the character constituent patterns specified by the element codes. Prior to character pattern generation, the validity of each element code is checked, and if the element code is found to be incorrect, character pattern generation is stopped and the character code is replaced with a predetermined specific code. do. This prevents the generation of half-finished characters based on incorrect specifications.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for generating prefabricated characters useful when displaying or printing prefabricated characters in various data processing devices.

A configurable character is a character created by combining a plurality of character components, and an example thereof is the Hangul character. The Hangul alphabet is composed of 19 consonants, 21 vowels, and 27 patchim (final consonant M) letters, which are combined into consonants + vowels and consonants + vowels + patchim. This number of combinations reaches 11.172.

Therefore, in a device capable of displaying or printing all Hangul characters, more than 10,000 types of character patterns must be created and stored in advance in the character generator. This would require a ROM with extremely large capacity.

The applicant has already proposed a Hangul character generation method that can minimize the memory capacity for storing patterns for character generation (for example, Japanese patent application No.
No. 83).

This Hangul character generation method corresponds to consonant codes, vowel codes, and patchim codes, and generates consonant character patterns, vowel character patterns, and patchim character patterns specified by those codes, respectively. When a Hangul character code consisting of a consonant code, a vowel code, and a patchwork code is given, the specified character pattern is read out from the memory by analyzing the code. It generates Hangul characters by composing the Japanese alphabet patterns.

According to this method, since it is sufficient to store only the necessary character patterns for consonants, vowels, and patchim in memory, a small memory capacity is required and all Hangul characters can be generated.

When generating Hangul characters by decomposing a given Hangul character code into consonants, vowels, and patchim codes (called jamo codes), there will be no problem if there is a jamo pattern that corresponds to all the jamo codes. If there is a character code (for example, an undefined code) that does not have a two-character character pattern, the generated Hangul character pattern will be half-finished. Such a mistake.

This may be caused by an operational error in the data processing device or by an error in the input operation for specifying the character pattern.

SUMMARY OF THE INVENTION It is an object of the present invention to prevent half-finished or erroneous character patterns from being generated when a nine-character component code (character code) is specified incorrectly.

This invention provides a method for configuring one assembly type character by combining a plurality of character components, in which an element code is assigned to each character component and a character code consisting of the element codes of the character components to be combined is obtained. When given, check the validity of the element code included in the character code, and if it is valid, combine the patterns of character components specified by the element code to generate the given prefabricated character pattern, It is characterized by replacing the given character code with a predetermined code if it is not valid.

According to the present invention, the validity of each element code is checked before a character pattern is generated by synthesizing single character component patterns. That is, it is checked whether a pattern has been created in advance for a given element code (whether it is an undefined code), etc. As a result of this check, if there is an error in the given element code, the character generation process is stopped and the character code containing the erroneous element code is replaced with a specific code, such as a space code.

Therefore, half-finished characters or characters with errors will not be generated, and such characters will not be printed or displayed. A character code containing an incorrect element code is replaced with a specific code, and the pattern specified by the specific code is displayed or printed (for example, a space is left behind), so that the error can be immediately identified. This is effective when the operator inputs a character code.

If the above specific code is a space code, by intentionally specifying an incorrect character code or element code,
It becomes possible to provide a space at that position for display or printing.

The above specific codes are of course not limited to spaces and 'codes, but any pattern of characters.

Needless to say, a code such as symbol 9 figure may be used.

DESCRIPTION OF EMBODIMENTS An embodiment in which the present invention is applied to a display in an electronic cash register (ECR) will be described in detail.

Depending on the dot arrangement in the display or printer, the dot pattern stored in ROM 32,42,52 will be slightly modified.

(2) Hangul character generation and command format Hangul characters are consonant characters (hereinafter simply referred to as consonants)19
, 21 vowels (hereinafter simply referred to as vowels) and 27 patchims (final consonants), consonant + vowel, consonant + vowel +
It is composed by combining them like a patch. The combination of consonant + vowel makes up 399 characters, and the combination of consonant + vowel + patchim makes up 10,773 characters, making the total number of these combinations 11.172.

In this combination, the consonant is placed on the left or above and the vowel is placed on the right or below. Patchim is.

It is always placed at the bottom of Hangul, which consists of a consonant and a vowel.

The display 3.4 displays Hangul characters, English alphabets, numbers, symbols, etc. (these are abbreviated as alphanumeric characters). One Hangul character is specified using 16 bits, and one alphanumeric character is specified using 8 bits.

FIG. 5(A) shows the format of the Hangul character designation code. The most significant bit (15th bit) is a classification code to identify whether it is a Hangul character or an alphanumeric character.
If this bit is 1, it is a Hangul character, and if it is 0, it is an alphanumeric character (although the alphanumeric code is made up of 8 bits as described later). The other 15 bits are used for specifying consonants, vowels, and patchims in groups of 5 bits from the highest order. That is, the 14th to 10th bits are a consonant code, the 9th to 5th bits are a vowel code, and the 4th to 0th bits are a patchum code. The possible range of these codes is shown in Figure 5 (B).
is shown. As mentioned above, there are 19 types of consonants, so these are designated by codes 00001 to 10011 ($O1 to $13 in hexadecimal notation). Although there are 21 types of vowels, the codes 00001 to 10101
It is specified by ($01 to $15 in hexadecimal notation). There are 27 types of patchim, so the code is oooooo~1111
16 out of 1 ($00 to $IF in hexadecimal notation)
$10 in hexadecimal representation. $11. $13. $00
and $IF except <27.

Patchym has 16 consonants and letters in common, so as we will see later, it shares its dot pattern with consonants. Out of 19 types of consonants, there are only 3 consonants that cannot be patched, and these are the code $10. Since these codes are specified as $11° and $13, these codes are excluded. Also, code $00. $IF means no patch. Therefore, patchim including no patchim
Code range is $OO~$IF to $10. $
11. Excluding $13.

In this way, with the amount of information of 16 bits.

11.172 Hangul characters can be specified.

FIG. 6(A) shows the format of a code specifying alphanumeric characters. In the ASCII code or JIS7 unit code for alphanumeric characters, all alphanumeric characters are represented by 7 bits. The most significant bit (seventh bit) is always O. In this embodiment, such a conventional code system is used as is. That is, the most significant bit O of the 8-bit alphanumeric code represents an alphanumeric character in the classification code, and the other 7 bits specify the alphanumeric character.

The possible range of this alphanumeric code is 00000000~
01111111 ($00 to $7F in hexadecimal notation)
It is.

7, 8, and 9 show actual consonant letters, vowel letters, and patchme letters specified by the above-mentioned consonant codes, vowel codes, and patchum codes. In these figures, the 5-bit code is divided into the upper 1 bit and the lower 4 bits, and these are expressed in hexadecimal numbers.

As mentioned above, consonants are placed on the left or above in the composition of Hangul characters. All consonants may be placed on the left or on the top. The consonants placed on the left in the composition of Hangul characters are called lateral consonants and are abbreviated as CV. The consonant when placed above is called the upper consonant and abbreviated as CH (see Figure 7).

Vowels are placed on the right or bottom in the composition of Hangul characters. Referring to Figure 8, the code $O placed to the right of the consonant
1~$04. The vowels from $OA to $OE are named vertical vowels and are abbreviated as vV. Codes placed under consonants $05-$0
Name the vowel number 9 the horizontal vowel.

Abbreviated as VH. Furthermore, there are vowels that are formed by combining vertical vowels and horizontal vowels. It is designated by the code $oF ~ $15, and in order to distinguish it from what is generally called a compound vowel, it is named here as a compound vowel, and VH+
It will be abbreviated as VV.

Generally, the 10 vowels in codes $O1 to $OA are called basic vowels, and the 11 vowels in codes $OB to $15 are called compound vowels. Compound vowels include those made up of a combination of basic vowels and those made up of a combination of a compound vowel and a basic vowel. As a term mainly referring to the latter (
(There are some exceptions) Use the final fourth vowel.

Patchim has the same letter as the consonant letter (code $
01~$OF, $12), and patchim (codes $14~$IE) made by a combination of two consonants.The latter will be called toru patchim. Both abbreviations are CP-.

As described above, one display section 35 on the display panel 34
is composed of dot segments 36 of 5 dots horizontally and 7 dots vertically, and because the number of dots is small, one Hangul character may not be fully displayed in one display section 35. Therefore, when the characters cannot be displayed in one display section, one Hangul character is displayed over two or three display sections. Although it generally becomes difficult to read when displayed over two or three display sections, efforts have been made to maintain optimal display quality to make it as easy to read as possible.

Figure 10 shows that all Hangul characters are 11.1 due to the limit of 5 x 7 dots on the display and the Hangul character pattern.
This shows that 72 characters are classified into 9 types of display patterns. Further, FIG. 11 shows the classification of display patterns based on vowels. This classification table is in ROM32
or stored in 42.

Referring also to FIG. 3, patterns 4 and 5 show combinations that can be displayed in one display section. Pattern 1, 2, 6.
7 and 8 indicate combinations that can be displayed in two display sections, and patterns 3 and 9 indicate Hangul character patterns that can be displayed over three display sections, respectively.

From the Hangul character display pattern shown in Figure 1O.

Works as a character generator <ROM32゜42
Students can understand what kind of consonant dot patterns, vowel dot patterns, and patchwork dot patterns need to be created in advance.

Referring to this diagram, among the consonants, the lateral consonant Cv is a vertical vowel V
It is used in combination with V (VV, VV2) (display patterns 1 to 3). For the lateral consonant Cv, one type of dot pattern for each letter is sufficient, and there are 19 lateral consonants C.
An example for v is shown in FIG. 12(A).

Upper consonant CH (CH, CH2)? ! Horizontal vowel VH (VH,
VH, VH, VH4) are used in combination (display patterns 4 to 9, especially display patterns 4 to 6). The standard battle pattern for the 19 upper consonants is shown in Figure 12 (B
) has been created as shown. This is the upper consonant CH
Set to 1. Depending on the combination, a dot pipe pattern with a small number of vertical dots may be required (for example, display pattern 5), so in addition to the standard dot pattern above, for specific five upper consonants, , as shown in the figure, another type of dot pattern has been created in advance.

This is called the upper consonant CH2.

Regarding consonants, whether they are the lateral consonant C■ or the -F consonant CH (both CH and CH2), they are designated by the same code (see Figure 7).

Regarding the dot tube patterns of the nine vertical vowels Vv (display patterns 1 to 3), in order to obtain the optimal display quality, we have divided into two types: one with a large number of vertical dots (this is called vV) and one with a small number (this is called VV2). Two types have been created: sushi. An example of this is shown in Figure 12 (
C).

Regarding the horizontal vowel VH (display patterns 4 to 6), four types are created depending on the number and position of vertical dots, an example of which is shown in FIG. 12 (CD). These are distinguished by VH, VH2, VH3°VH. There are 5 horizontal vowels, all of which have 4 types of dots.
There is no set pattern, but settings are made as needed.

As explained using FIG. 8, the designation codes for vertical vowels and horizontal vowels are different.

The vowels in display patterns 7 to 9 are complex vowels (code $OF
~$15; see Figure 8), horizontal vowel VH and vertical vowel vV
and can be represented by the combination VH+VV. For example, in display patterns 7 and 9, V H
1 or vH2+vV, and in pattern 8 it is VHl or vH2+VV2. Therefore, dot patterns for complex vowels are not created.

Patchim CP is located below the vertical vowel (display pattern 2,
8) or the right position of Hangul characters (display pattern 3, 6)
．． 9). As shown in Figure 12 (E) and (F), for 27 patches including toll patches, the standard bottom pattern (denoted as CPl) and for 5 specific patches are used. Dots with a small number of vertical dots
A pattern (referred to as C20) is defined.

The 109 dot patterns shown in FIGS. 12(A) to 12(F) are the ROM 32. which acts as a character generator.
42 is stored in advance. These dots
FIG. 13 summarizes the relationship between patterns and codes. The O mark indicates that there is a dot pattern.

The number in parentheses is the number of dots occupying the vertical direction (hereinafter referred to as
(referred to as the number of vertical dots). 2 types of upper consonants, 2
Sub-codes are used to distinguish between different types of vertical vowels, four types of horizontal vowels, and two types of patchims.

Further, data indicating the number of vertical dots shown in parentheses is also stored in advance in the ROM in the form of a table or the like. In FIG. 13, for convenience of tabulation, some of the consonants and patchim are shown using the same code and Hangul alphabet.

- As mentioned above, since the dot pattern of a complex vowel is created by a combination of a horizontal vowel and a vertical vowel, the dot pattern of a complex vowel is not stored in the ROM. Instead, a table of combinations of horizontal vowels and vertical vowels is created in advance as shown in Figure 14 in order to generate dot patterns of compound vowels, and is stored in ROM3.
It is set to 2.42.

(3) Display processing Figure 15 shows the sub (:PU31)
It shows the format of the display (or print) command given to or 41 and how the characters instructed by this command are displayed (printed). In a display command, a command code is placed at the beginning, followed by codes (character code data) specifying characters to be displayed, arranged in the order of display position. As mentioned above, one Hangul character is specified by a 2-byte (16-bit) code, and each alphanumeric character is specified by a 1-byte (8-bit) code. Generally, Hangul characters and alphanumeric characters are mixed in the character code data. Furthermore, the number of bytes is different between the Hangul code and the alphanumeric code. Therefore, when the sub CPU 31 or 41 receives a display command, it must first distinguish between Hangul characters and alphanumeric characters.

When the display command is sent from the main CPU II, it is sent to the RAM 33 connected to the sub CPtJll or 41.
or 43 or other suitable buffer. address to specify this store location.
A pointer is used, and the address pointer specifies the location of one byte as one unit. To simplify the explanation, as shown in the middle part of Figure 15, the address point of the storage location of the first 1 byte of character code data in the display command is changed to 02 and the address point of the next 1 byte of data. Store location 1. Assume that consecutive numbers are assigned to the storage locations of 1 byte as address points.

FIG. 23 shows a process for determining Hangul characters and alphanumeric characters in a display command executed by the sub CPU 31 or 41.

An address pointer is first initialized and set to a value indicating the address point (ie, 0) of the first store location (step 101). It is checked whether the most significant bit of the 2 bytes of data in the code from the point indicated by this address pointer is 0 or 1 (step 102.
103). As explained with reference to FIGS. 5 and 6, the most significant bit is the classification code, and if this classification code is 1, the 2-byte code Φ data containing it indicates a Hangul character, and it is 0. In the case of , the 1-byte code data containing it indicates alphanumeric characters.

If the most significant bit is -1, it is determined that it is a Hangul character code, and that fact is stored in a predetermined area of the RAM 33 or 43 (step 104). After this, add 2 to the address pointer (step 105) and step 1
02, and similar processing is repeated.

If the most significant bit is 0, it is determined that it is an alphanumeric code, and this fact is stored in the RAM (step 10B), the address pointer is incremented by 1 (step 107), and the process returns to step 102.

When the analysis of all the character code data in the display command is completed by repeating the above process (step 108), this determination process ends.

Based on the results of this analysis, the next step is to generate a dot pattern represented by each code. will be displayed.

Prior to the dot pattern generation process, a process is performed to determine whether the single character code is correct or incorrect. As mentioned above, the Hangul character code is composed of a 1-class code, a consonant code, a vowel code, and a patchum code, and the possible ranges of the consonant code, vowel code, and patchum code are predetermined. If these character codes of a given No. 1 character code are not within the above range, the designation of that character code is incorrect;
It is not possible to create a correct Hangul character dot pattern. This correctness determination process checks whether the given Hangul character code is valid, and the details thereof are shown in FIG. This process is performed by sub CPU3
1 or 41.

The 2-byte (16-bit) character code that was determined to be a Hangul character code by the above analysis process is read into a buffer, etc., and is used as the classification code (1 bit), consonant code (5 bits), vowel code (5 bits), etc. bit) and Patchym fist code (5 bits) (step 111)
). The state of this disassembly process is shown in the upper and middle rows of FIG. 16.

For example, if the 2-byte Hangul character code is $843F in hexadecimal representation, the consonant code is $O1, the vowel code is $01. It can be seen that the patch number code is $lF.

Among the codes decomposed in this way, it is first checked whether the consonant code is within the predefined range of $O1 to $13 (step 112). If it is within this range, the next step is to check and check the vowel code, and it is checked whether the vowel code is within the range of $O1 to $15 (step 113). If the vowel code is within the above range, the patch chord is within the range of $00 to $1F and $10. $11. It is checked whether the value is other than $13 (step 114). Patchim・
If the code is also found to be the one defined above, it is determined that the Hangul character code is correct (step 115), and the process proceeds to Hangul character pattern generation processing, which will be described later.

If the letter code is not within the predetermined range in any of steps 112 to 114 above.

It is determined that the Hangul character code is incorrect (step 117). Then, a space code is stored in the buffer in the RAM 33.43 in place of this Hangul character code (step 118).

FIG. 22 shows a dot pattern displayed on the display 34 corresponding to the character code in the given character code data. FIG. 22(A) shows the case where there are no errors in all Hangul character codes. Figure 22 (B)
shows that one Hangul character code $FFFF is incorrect, and therefore, this Hangul character code is replaced with a space code, resulting in one display section being blank (no characters are displayed). In this way, one display section or two or more display sections may be left blank by the space code.

However, in step 118, the erroneous Hangul character code may be replaced with another character or symbol code, and in that case, the character, symbol, etc. represented by the replaced code will be displayed.

For alphanumeric codes, the correctness determination process shown in FIG. 24 is not necessary, but may of course be performed.

Since it is sufficient to display one designated alphanumeric character in one display section 35 at a designated position, the display can be performed in a conventionally known manner.

Of course, alphanumeric dot patterns are also stored in ROM 32 or 42.

The dot pattern generation and display process for Hangul characters is somewhat complicated, and a part of the process procedure is shown in FIG. This process is also executed by the sub CPU 31 or 41.

First, it is determined whether or not there is a patch by decoding the patch code (step 122). Since it has already been checked in step 114 of FIG. 24 whether the patchm code is within the possible range, it is sufficient here to check whether the patchm code is $00 or $IF, which indicates no patchm. Patchim code $00
Otherwise, if it is $IF, it is determined that there is no patching, and in other cases, it is determined that there is patching.

If there is no patch, see Figure 11.

The pattern types displayed are patterns 1, 4, and 7, and these are classified according to the type of vowel. Therefore, the type of vowel indicated by the vowel code is checked (step 123), and if the vowel code is a vertical vowel, display pattern 1 is generated (step 124), and if it is a horizontal vowel, display pattern 4 is generated (step 124). Step 125), and if it is a compound vowel, the process proceeds to display pattern 7 generation processing (step 126).

In the example shown in FIG. 16, the vowel code $01 is a vertical vowel, so the display processing of 9 display pattern 1 (step 12
4) is performed. This process is the simplest. Two display sections 35 within the display panel 34 are used, the first display section showing the dot pattern indicated by the consonant code, and the second display section showing the two types of dot patterns specified by the vowel code. Pattern V of dot patterns
■1 is displayed respectively. Consonant code $01. A display example for the vowel code $O1 is shown in the lower part of FIG. 1α.

Display pattern 4 is divided into two patterns. These are the combinations of the upper consonant CH and the horizontal vowel ■H1 (this is called pattern 4-1), and the combination of the upper consonant CH and the horizontal vowel V
This is a combination with H2 (this is called pattern 4-2). These two display patterns are shown in FIG.

As can be seen from FIG. 13, the number of vertical bits of the old consonant CH1 is 3 or 4. On the other hand, the number of vertical bits of the horizontal device=Va1 is 3 or 1. Therefore, the upper consonant C
In any combination of H, and the horizontal vowel VHt, the total number of vertical bits will not exceed 7, which is the number of vertical bits of the display section 35, and all Hangul characters that form pattern 4 will, in principle, match the display pattern. It can be displayed in 4-1.

However, the upper consonant code $04. $OC or $O
In the combination of the letter E and the letter of the horizontal vowel code $07 or $08, the dot pattern CH and V H1
It becomes very difficult to see the characters generated by compositing with. Therefore, a dot pattern VH2 having two vertical bits is used instead of the horizontal vowel dot pattern VHt. And upper consonant dot pattern CH in the upper half
, and the horizontal vowel dot pattern vH2 in the lower half. This is display pattern 4-2.

Therefore, in the process of generating display pattern 4 in step 125, it is first determined whether the combination of upper consonant and horizontal vowel in the given character code is a specific combination that should form pattern 4-2 described above. If it is not the above-mentioned specific item, it is displayed in one display section according to pattern 4-1, and if it is specific, it is displayed in one display section according to pattern 4-2. FIG. 18 shows how the dot pattern of display pattern 4-2 is generated.

This method of generating pattern 4 is used in generating processes of patterns 6.7.8 and 9, which will be described later.

Details of the algorithm for generating display pattern 7 in step 12B are shown in FIG. FIG. 19 shows an example of the process of generating Hangul characters including complex vowels, which is performed according to this algorithm. Referring to these figures, first, complex vowels are decomposed into horizontal vowels and vertical vowels (step 131). As mentioned above, the dot-dot competition pattern for the final fourth vowel is not created in advance.

Instead, a combination table (see FIG. 14) of horizontal vowels and vertical vowels constituting a complex vowel is stored in the ROM 32 or 42. By referring to this combination table, horizontal vowels (VH
Or find the chord of VH2) and the chord of vertical vowel (VVl). In the example of FIG. 19, since a quadruple vowel is specified after the code $OF, it can be seen that this can be composed of the horizontal vowel of the code $05 and the vertical vowel of the code $O1.

The Hangul characters of display pattern 7 are displayed using two display sections 35 of display panel 34. next.

The dot of the upper consonant CH1 specified by the consonant code.
The pattern and the horizontal vowel (VH or VH2) searched for in the above process are synthesized using the display pattern 4 creation method described above, and are displayed in the first display section (step 1
32). In the example of FIG. 19, the upper consonant of code $O1 and the horizontal vowel of code $05 are combined. Subsequently, the dot pattern of the vertical vowel (VVl) retrieved in the above process is displayed in the second display section (step 133).
.

If it is determined in step 122 of FIG. 25 that there is patching, the process proceeds to the process shown in FIG. 27. Here too, the vowel code is first checked to determine whether it is a vertical vowel, horizontal vowel, or compound vowel (step 141).

In the case of vertical vowels, display pattern 2 or 3 is used, as can be seen from the classification table in FIG. Display pattern 2
1 displays one Hangul character in two display sections, and 1 display pattern 3 displays one Hangul character using three display sections. Since it is preferable to display one Hangul character in as few display sections as possible, it is first checked whether pattern 2 can be displayed (step 142). In both display patterns 2 and 3, the lateral consonant specified by the consonant code is displayed in the first display section. Therefore, it is checked whether the combination of the vertical vowel (vowel vv2 with a small number of vertical dots) and the patchim CP1 constituting the Hangul character can fit into one display section.

Referring to Figure 13, the number of vertical dots of vertical vowel vv2 is 3.
or 4, and the number of vertical dots in Patchim CP1 is 3.4
Or 5. Therefore, the combinations that can be displayed in one display section with 7 vertical dots are as follows.

Vertical vowel ■v2 with 3 vertical dots and patchum CP with 3 vertical dots, ■v2 with 3 vertical dots and CP with 4 vertical dots
and ■v2 with 4 vertical dots and CPl with 3 vertical dots
It is. In these cases, a dot pattern of display pattern 2 is generated (step 145). In this process, the dot pattern and patch pattern of the vertical vowel ■v2 specified by the vowel code are displayed in the second display section.
The dot pattern of patch pattern CP1 specified by the code is combined and displayed.

In cases other than the above combinations, display pattern 3 generation processing is performed (step 14B). In this process, the second
The pattern with the largest number of vertical dots among the vertical vowel dot patterns specified by the vowel code is displayed in the second display section, and the dot pattern of Patchum CP1 specified in the third display section is displayed. be done.

If the vowel type is determined to be a horizontal vowel, it is checked whether Hangul characters can be represented by display pattern 5 (step 143). Display pattern 5 is a combination of consonants, vowels and patchims.
It is to be placed in the display area. If the combination of display patterns 5 is possible, the specified Hangul characters are displayed in this pattern 5, and if the combination is not possible, display pattern 6 is used. Display pattern 6 expresses one Hangul character in two display sections by displaying a combination of consonants and vowels in the first display section and patchims in the second display section.

The display pattern 5 is a display pattern 5-1.5- as shown in FIG.
2 and 5-3. Display pattern 5-1 is
It is constructed by vertically arranging a consonant dot pattern CH2 with two vertical dots, a vowel dot pattern VH3 with two vertical dots, and a patchum dot pattern CPl with three vertical dots. Display pattern 5-2 is CHl with 3 vertical bits, VH4 with 2 vertical dots, and CP with 2 vertical dots.
2, the pattern 5-3 is a CH with 3 vertical dots,
, vH3 having one vertical dot, and CPl having three vertical dots. Pattern 5-2 is preferentially adopted over display pattern 5-1 because the higher the number of vertical dots in the top row of consonants, the higher the quality of Hangul characters. These display patterns 5-1 to 5-3
Figure 21 shows the consonants, vowels, and patchim letters that make up the word.

The Hangul characters specified by the code are pattern 5-
In checking whether it can be expressed as one of 1 to 5-3, the vowel code is first checked. Those whose vowel code has a dot pattern VH4 ($ 0
5. $06. $07゜$08), there is a possibility that it can be expressed by display pattern 5-2. In this case, it indicates a letter with a primary consonant code (C
Some Hl have 4 vertical dots), and patch pattern C has 2 vertical dots.
Pattern 5 on the condition that P 2 indicates the letter
-2 is selected. Vowel chord is dot pattern vH
4 (this vowel code also has dot pattern VH3), but if the above consonant and patchum conditions are not met, the secondary consonant code will be a dot with a vertical dot number of 2.・The patch code must have a pattern CH (CH2 with 2 vertical dots is included in CH with 3 vertical dots), and the patch cord must have a dot pattern cP1 with 3 vertical dots. It is determined that the display pattern 5-1 can be displayed. Even if the vowel code has dot pattern VH4, the consonant code or patchim code has display pattern 5-1 or 5-.
If condition 2 is not satisfied, it is determined that display pattern 6 is to be used.

In order to see if it can be expressed with the remaining display pattern 5-3, we created a dot pattern v with a vowel code of 1 vertical dot.
Check whether it has H3 (this is only the vowel code $09), and if so, the consonant code has a dot order pattern CH1 with 3 vertical dots, and the patchim code has 3 vertical dots. dot order pattern CP
Display pattern 5-3 is adopted on the condition that it has a value of 1. In other cases, display pattern 6 is used.

If it is determined that the display pattern 5-1, 5-2 or 5-3 can be displayed, the dot pattern corresponding to that pattern is read from the ROM 32 or 42, and these are superimposed to be designated as one display section. The Hangul characters are displayed (step 147).

In other cases, proceed to the generation process of display pattern 6 (
Step 148). In the display processing of display pattern 6, the dot patterns CH and VH or VH2 of the given consonant code and vowel code are displayed in the first display section according to the same method as display pattern 4 shown in FIG. The display pattern CPl specified by the patch code is displayed in the second display section.

When it is determined that the vowel is a compound vowel in the analysis of the vowel code in step 141, it is determined whether or not it can be represented by 9 display pattern 8 (step 144). Display pattern 8 is one in which 1 no. 1 nguru characters are expressed in two display sections. If display pattern 8 cannot be used, display pattern 9 is adopted in which one Hangul character is expressed using three display sections.

To determine whether or not it can be expressed using display pattern 8, use the table shown in Figure 14 to determine whether a complex vowel can be represented by a horizontal vowel (VH or VH2) and a vertical vowel ( VV or vv2). Next, it is determined whether the vertical vowel divided into one segment and the given patch can be expressed in one display section using the same method as the process for determining whether or not they can be expressed in display pattern 2 described above. If it can be displayed, pattern 8 is adopted, and if it is not possible, pattern 9 is adopted.

If it is possible to display using display pattern 8, first, by using the method used in the display processing of display pattern 4, the consonant code (CHl) and the above decomposed horizontal vowel code (VH
Alternatively, the dot patterns of VH2) are stacked one above the other and displayed in the first display section, and then the dot patterns of the decomposed vertical vowel and the specified patch are displayed in the second display section.
The patterns are displayed in an overlapping manner (step 149). When display pattern 9 is displayed, the same process as pattern 8 above is applied to the first display section, and the same process is applied to the second and third display sections.
For the th display section, the same process as in pattern 3 is used (step 150).
