Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character output device that processes character code data when given, and outputs a character turn that can be visually recognized by humans using, for example, a display device or a printer. .

Currently, in the field of computers in Japan, terminal devices that can process information in Japanese, including kanji, have become widespread. This has made it easier to input and output information in Japanese to computers. However, Japanese information processing, including kanji, has the following drawbacks. First, there are a large number of characters to handle, and key operations are complicated when inputting such character information into a keypad computer.

In other words, it is not possible to input using simple key operations like inputting in English. Second, it is not possible to adopt an international bit number coding system. Internationally, a 7-bit code system that represents 128 types of characters is common. The 8-bit code system, which consists of 7 bits plus 8 bits, can also be used internationally. However, the Japanese character code system, which includes kanji, requires 13 or more.

Therefore, computer software and /1-ware created based on such character encoding systems are not internationally compatible.

Therefore, one idea is to use an 8-bit character encoding system to create Japanese sentences that are easy for ordinary Japanese people to read. When computers were first introduced to Japan, only katakana, which was technically easy to handle, was used as the Japanese character.

The character code for katakana created for this purpose is JIS.
- Chill with C6220. In this way, in the field of computers, all Japanese sentences have traditionally been expressed in katakana, and this has led to the fixed concept among ordinary Japanese people that sentences output by computers are difficult to read. Figure 1 shows an example of a difficult-to-read Japanese sentence expressed only in katakana. Ordinary Japanese people are most accustomed to Japanese sentences that are a mixture of kanji and hiragana. This is thought to be a major reason why Japanese sentences containing only katakana are difficult to read. So, given that hiragana is more familiar to many Japanese people, what about Japanese sentences expressed only in hiragana? The same content shown in the example of FIG. 1 is shown in hiragana in FIG. 2. As can be seen from the example shown in Figure 2, Japanese sentences expressed only in hiragana are not very easy to read for ordinary Japanese people, just like the example in Figure 1.

Therefore, as a new attempt, I decided to use a mixture of Japanese phonetic characters, katakana and hiragana. The character code system used in this case is an 8-bit code as shown in FIG. 3, but it can cover characters of the 3S class including katakana, hiragana, and alphabets. An example using characters of this code system is shown in FIG. This example also expresses the same content as the examples shown in FIGS. 1 and 2. However, it is much easier to read than Figures 1 and 2, and I think you can read it without any hesitation. In this way, a new style different from the conventional one using phonetic characters (kana characters), namely the kana character renaissance style, is used to enrich the meaning.Sentences like this are hereinafter referred to as 1cal style sentences.This 1
Sentences in "Kal Style" are not just a matter of changing the type of letters, but various devices are used. One of them is the "one-part writing key". The idea is to provide an appropriate space between words.Generally, in the case of a sentence containing kanji, one word is often formed from only kanji, so even if it is written solidly, there is no way to separate the words. - is quite clear.However, sentences written using only phonetic alphabets are extremely difficult to read because the punctuation marks cannot be seen unless there are spaces between words.Written using alphabets Writings from other countries usually use this type of method. There are several types of 'partitioning 1' methods. A representative example is the Ichiriki Namoji-kai method. In principle, single-character particles, such as 1 for 1, ' for ', ゝ', 'ni', 1 for', etc., are written so that they can be heard in the previous word, and particles of two or more hands, such as 1 Only', - to ",' Yoshi! etc. are written independently. Sentences written using this method appear to have inflected nouns, similar to case declension in German. In general, particles appear extremely frequently in Japanese sentences. Therefore, if particles are handled differently, even Japanese sentences with the same content can give very different impressions to the reader. In the sentence of 1 cal style' shown in Figure 4, it is a little different from the above 1 Kanamoji ukata 2'', in that the − character particle is also made independent.In addition, the sentence of 1 cal style' is a combination of two − character particles. Particles that have a strong - character function as particles, in other words, those that would be better separated by nine directions for an average Japanese person, are made independent.If you adopt this method, it will be easier to read. It becomes a sentence.

However, when single-letter words are written independently in this way, the spaces between words are too frequent and the writing becomes a little disorganized. One possible solution is to shorten the width of the space between words. The same sentence as in the example shown in Figure 4 is written with a shorter space width (here 1/2
(width for characters) and is shown in FIG. In this way, the example in Figure 4 becomes even easier to read, and just like a sentence containing kanji, a normal Japanese person can read it with almost no resistance. However, the spaces normally used in texts mainly written in Roman letters must be distinguished from the above-mentioned 1/2 character space by having a fixed width of one character or approximately equal to it. For this reason, if a conventional character output device is used to output characters, handling of spaces becomes complicated. For example, when an operator inputs two types of spaces into the above-mentioned character output device, key operations become cumbersome.

The present invention has been made in view of the above drawbacks, and its purpose is to:
To provide a character output device which automatically changes the width of a space only immediately after a kana character and outputs an easy-to-read kana character sentence.

Therefore, the present invention has a holding means for holding character code data for one character, and judges whether the code data given sequentially is character code data or space code data, and if the judgment result is character code data, the above The content of the holding means is transferred to the character pattern output circuit regardless of the content of the holding means, and the content of the holding means is rewritten to become character code data, and if the above determination result is space code data, the content of the holding means is It is determined whether the character code data is in a predetermined range or not, and if the result of this determination is the character code in the predetermined range, the space width is set to a predetermined space width narrower than the original space width. The above objective was achieved by controlling the

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 6 is a block diagram of an embodiment using a microprocessor. In the figure, 1 is a character output mechanism, specifically a printing device (printer) or a character display device. In this case, if the printing device is 1. The order of the buildings such as Tomatotrix, Jutsuto Gen, Seinetsu Shiki, etc. does not matter. Further, as long as the character display device is used, it does not matter whether it is a CRT type, liquid crystal type, plasma type, or the like. 2 is a character pattern output circuit. The character number output circuit 2 processes character code data when it is given it, and operates the character output mechanism 1 in accordance with the given character code data. That is, if the given character code data is graphic character code data, the character pattern output circuit 2 reads character turn data from its own character generator and outputs the read character. It outputs a noku turn to the character output mechanism 1, and if the given code data is function code data, it outputs a signal to the character output mechanism 1 to perform control in accordance with this data. In the present invention, in addition to general function code data, code data for controlling the space width is determined in advance. The character pattern output circuit 2 is equipped with a space width control circuit 3 that changes the space width in accordance with this code data. 4 is an interface circuit. The interface circuit 4 is a circuit for exchanging data between this device and a host computer or other terminal equipment (not shown).

5 is a CPU, 6 is a ROM, 7 is a RAM, 8 is a register that can store character code data for one character, and 9 is a bus that connects these with the character pattern output circuit 2 and the interface circuit 4. be. Based on the program stored in the ROM 6, the CPU 5 receives data from the outside via the ink face circuit 4, or processes the data by exchanging data with the RAM 7 and register 8. The data processed according to the character pattern output circuit 2 is outputted to the character pattern output circuit 2. R.O.
The program written in M6 is shown in a flowchart as shown in FIG. That is, the CPU 5 functions as each means shown in FIG.

The operation of the apparatus of this embodiment will be explained below based on the flowchart of FIG.

First, when starting, the CPU 5 determines in step 101 whether or not code data has been given to the interface circuit 4, and if there is code data, branches to YES. Next, in step 102, the CPU 5 determines whether the given code data is character code data. If the CPU 5 determines YES in step 102, it proceeds to step 103, transfers the character code data given here to the character pattern output circuit 1, and proceeds to step 103.

After storing the character code data given in step 104 in register 8, the process returns to step 101.

If the determination result in step 102 is No, the CPU 5 proceeds to step 105, where it determines whether or not the given code data is space code data. If the result of this judgment is YES, the CPU 5 proceeds to step 106, where it judges whether the contents of the register 8 are hiragana character code data or not.
The process proceeds to step 07, where the code data for making the space width 1/2 character is output to the space width control circuit 3, and then the process proceeds to step 104, where the space code is stored in the register 8, and then the process returns to step 101. . Step 106
If the judgment result is NO, the CPU 5 proceeds to step 108.
The process proceeds to step 107, where it is determined whether the contents of register 8 are katakana character code data, and if YES, the process proceeds to step 107, where, as in the case of hiragana described above,
After outputting the code data for reducing the space width to 1/2 character to the space width control circuit 3, the process proceeds to step 104. If the judgment result in Step 108 is NO, the CPU
Step 5 proceeds to step 109, where code data for setting the space width of the space width control circuit 3 to one character is output, and then the process proceeds to step 104.

If the determination result in step 105 is NO, the CPU 5 determines that the given code data is normal function code data ρλ, etc., and performs processing based on this in step 110 (control routine). The processing in the control routine is the same as the conventional one, so a description thereof will be omitted.

In this way, the characters and spaces sequentially output from the apparatus of this embodiment constitute a very easy-to-read sentence, as shown in FIG.

In the example shown in FIG. 5, characters with voiced or handakuten are expressed in the space of one character.

Generally, it is not possible to represent all phonetic characters, including characters with voiced and half-voiced marks, using an 8-bit code system as shown in FIG. However, the character generator of the above embodiment device is made to hold a character pattern represented by a space for one character with a voiced or half-voiced mark, and this character pattern can be generated using predetermined character code data. I'll keep it. Then, when the character code data of a character to which a voiced or half-voiced mark is to be attached and the character code data of only a voiced or half-voiced mark are consecutively given, the non-embodiment device d can convert the character code data from these two character code data. Create the above-mentioned predetermined character code data, or read out a character pattern with a voiced mark or a half-voiced mark expressed by a space of one character from the character generator according to the character code data,
If a function to output this is also provided, it is possible to express the ``dakuten'' or ``handakuten ``su'' in the space of one character. A separate application is currently being filed for a device related to this (Japanese Patent Application No. 58-0
40583).

Furthermore, the character codes handled in this embodiment are included in the 8-bit character code system shown in FIG. As mentioned above, all characters handled by computers, including alphabets, numbers, and symbols, are represented by a 7-bit character code. However, when exchanging information, 8 bits, which is the 7 bits representing the character code plus 1 bit used for check codes, etc.
Bit data is treated as one information unit.

Therefore, information created using an 8-bit character code and information created using a 7-bit character code can be exchanged relatively easily. However, to make it even easier, a character code that should be expressed in 8 bits may be treated as a 7-bit character code from the beginning. 3. Romaji characters, katakana characters, and hiragana characters. An example in which the character codes of all characters included in the ifI class character series are treated as 7-bit codes will be described below. Normally, the character codes of all the characters included in the three types of character series mentioned above cannot be represented by a 7-bit code system. Therefore, the character codes of each character series are kept independent and remain in the 7-bit code system.

Then, one of the character series is defined as the main series, and the other two are defined as the sub-series (for example, Roman characters are defined as the main series, and hiragana and katakana are defined as the sub-series). and,
Two specific characters commonly set in each series: 7-C are used as sub-series designation codes each indicating one of the sub-series. When inputting Japanese sentences using characters included in each character encoding system defined in this way into a computer, the first character to be input is a character in the main series or a character common to each series (the subseries mentioned above). ), enter the character code of that character,
If it is a sub-series, input the character code of the selected character for which the sub-series designation code (7-bit code) was input.

If the character series to be input next is the same as the character series input last time, enter the character code of that character as is, and if it is different, enter the code indicating that series and then enter the character code of that character. (If it is a main sequence character or a common character, enter the character code data of that character as is.) In the same manner, the characters to be input are sequentially processed. In order to input each character into a computer using a 7-bit character code in this way and then output these characters from the device of this embodiment, the device of this embodiment must be equipped with the following functions. good. First, the device of this embodiment is equipped with a register that holds 2-bit code data, and the character generator is a 9-bit code.
The character patterns of all three types of characters are read out using the default character code. Then, if the given character code is the character code of the main sequence character or the character code of the common character, the contents of the above register are set as the 2-bit code indicating the main sequence, and this 2-bit code is converted into the given 7 bits. Create 9-bit code data added to the bit character code, read out the character pattern pre-stored in the character generator based on this data, and output it. If there is, based on this, the contents of the register are 2-bit indicating the sub-series.

If the given character code is a normal character code, add the 2-bit code that is the contents of the above register to the given 7-bit character code to create 9-bit, tcode data. Based on this, a character pattern stored in advance in the character generator is read out and output. If the device of this embodiment is equipped with such a function, character codes of three types of characters can be handled as 7-bit codes. A separate application for a device related to this is also pending (Japanese Patent Application No. 58-185514).

〔Effect of the invention〕

As explained above, according to the present invention, when a phonetic text is created using the separate writing method, the space width can be adjusted without the need for any special operations, making it easy to read and visually beautiful. Can express sentences.
