The present invention relates to a Hangul output device, and more particularly, to a Hangul output device for outputting characters including Hangul material based on a predetermined format.

The phonetic symbol unit that composes the Hangul material is called a phoneme, and one character consists of a plurality of combinations of phonemes, such as consonant vowels.

In general, one letter one code (1 byte: byte) is assigned, and one letter of Korean alphabet is generally composed of two letters to four letters. Non-Hangul characters, for example, alphanumeric characters, are usually given with one output code (1 byte) per one-character output code (1 byte).

Therefore, even if there is a format symbol that is output at a certain position for each line in order to perform the format alignment of the format symbol when outputting in a specific format format, the data of each line is used. The format code in this example, for example, a ":" code, may be arranged in alignment with a predetermined byte position in the memory, and output in correspondence with the byte position.

However, in the output of Hangul characters, the number of codes constituting one character is variable, so the number of codes is variable, and in the case of data containing Hangul characters, the format symbol at a certain byte position in every line of data is used. It is not necessarily output to the byte-compatible output location.

If the format code that needs to be output at a certain position for each line is set for the above reason, the actual number of output lines is calculated instead of the number of output codes, and a space code is inserted into the memory, or a format code for each line. You need to position the data.

As a result, there is a drawback that the data length of each line becomes indeterminate length.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned problems. Even when outputting data including Korean characters in a predetermined format, the output length of Korean characters is not conscious, and the data length of one line is fixed. It is to provide a Hangul output device that can be handled with.

A feature of the present invention for achieving the above object is that if the format code corresponding to the preset format symbol is in the data, the format code of the format code is output after the space output by the difference between the position counter and the code counter. To print a symbol.

Therefore, the format code position can be set without storing the space code for matching the format code output position in the memory, and the variation of the data length of one line due to the space code input can be eliminated.

EMBODIMENT OF THE INVENTION Next, the Example of this invention is described in detail using drawing.

1 is a block diagram of a Hangul output device according to an embodiment of the present invention.

Data is converted into an output character pattern composed of a combination of dots in the output control circuit 1 and sent to the printing device 8 or the display device 9.

The output control circuit 1 includes a memory for storing the character code for output, a character pattern generator for converting the character code read in correspondence with the output position, and a character code corresponding to the phoneme of Korean characters. A judging unit that detects a plurality of phoneme-corresponding codes constituting one character, and determines what Hangul characters are generated from the combination of these codes; and a Hangul character pattern generating a Hangul character pattern in accordance with the judgment result. It has a generation part.

In addition, the phoneme correspondence code of Hangul characters has a bit condition different from that of general character codes.

Since the Hangul character pattern has a somewhat complicated line, the number of dots of the print pattern is needed as in the case of Hanja (漢字). The character pattern of the left half quotient and the right half quotient in many first terms may be printed.

This also applies to the display.

In the following description, the description is based on the premise that the number of elements (display dots) of the print head is large and that one Korean character is equal to one English number. Particularly, the printing control part of the Korean character is shown. This is the same as normal output control. In FIG. 1, the output control circuit 1 generates an output signal of one character quotient irrespective of general characters and Korean characters, and prints (displays) the printing device 8 (or display device 9). Generates a signal of one letter quoting termination.

This end output signal is sent to the count-up terminal CU of the position counter (counter) 2 and becomes a count-up signal.

The format symbol is generally a mark symbol, a line, a border, etc., which is used to classify items such as a trademark or a product name, and the contents thereof, and is set in advance so as to be later than the word having the longest byte in the word displayed by each item part. It is stored in the memory corresponding to the set byte position.

The output control circuit 1 sends a count up signal to the position counter 2 each time the output position advances by one term, and the position counter 2 stores the actual printing term position. The output control circuit 1 also sends a count-up signal to the count-up terminal CU of the output code number counter 3 each time one code is read from the memory, and stores the output code number in the output code number counter.

The position counter 2 and the output code number counter 3 output a signal to the reset terminal R from the output control circuit 1 under the condition of AND and the signal from the determination unit 7 at the time when the format code is output. Reset.

The format code register 6 stores format symbols designated by an upper apparatus such as a central processing unit, and the code judging section 7 stores the code read from the memory and the format code register 6. When the contents are compared and judged, the space output circuit 5 is controlled to generate a space output for position matching.

The output of the position counter 2 and the byte counter 3 is an input of the subtraction circuit 4, and the subtraction circuit 4 passes this pressure difference to the space output circuit 5.

The space output circuit 5 generates a space output signal by the number of parameters passed by the subtraction circuit 4, and performs space control of the printing (display) through the output control circuit 1. In the case of Hangul characters, there is a difference between the number of codes and the number of arguments (display), so the subtraction circuit 4 stores a fixed value, but in the case of ordinary characters, the number of codes is equal to the number of arguments (display). The value of 4) becomes "0" and as a result, no space signal is generated.

The configuration and operation of the space output circuit 5 will be described in more detail as follows. The space output circuit 5 can be configured by a simple flip flop.

That is, it is determined whether or not the code data read out from the memory by the determination unit 7 and the contents of the code register 6 correspond to the specified format code data.

As a result of this determination, when it is determined that it is a predetermined (specified) format code, a signal is output from this determination unit 7, and this signal is input to the set terminal of the flip-flop made up of the space output circuit.

As a result, the flip-flop outputs a signal for performing a space output at a predetermined timing.

This timing is synchronized with the subtraction timing in the subtraction circuit 4.

On the other hand, in the subtraction circuit 4, the contents of the position counter 2 and the output code number counter 3 are compared, and the space signal is not changed in the flip-flop until the two correspond to each other, that is, until the difference between them becomes "0". It is out. Thus, if they match, a signal is input to the reset terminal of the flip-flop in the circuit 4 and the flip-flop is reset. As a result, since the flip-flop is set until the values of the counters 2 and 3 coincide, the space signal is output as many as the difference indicated by the counters.

Next, the operation of this circuit will be described.

FIG. 2 is a data processing state diagram of an operation example of the embodiment shown in FIG.

When the phoneme code number of the Hangul characters, that is, four characters of "a", "2", "", "b" and "b" is input from step (1) to step (4) indicated by 1, four bytes are output by one character in the output control circuit (1). A character pattern "tube" is generated by detecting the character of Hangul, and one character of Hangul is outputted within one term, and at the same time, a count-up signal is sent to the output code number counter 3 as many times as each step.

In this example, since the number of steps is "4", the count-up signal is sent four times. As a result, the content of the output code number counter 3 becomes "4" in step 4.

In addition, the counter-up signal is sent out only once to the position counter 2 indicating the actual printing position, and the contents of the position counter 2 become " 1 "

In step 5, if the code of the format symbol ":" is read out and matches the code contents set in the format code register 6 in advance, an output is generated from the code judging unit 7.

When this output occurs, the output of the format symbol ":" is temporarily held so that the space for position registration from the space output circuit 5 is output from step 6 to step 6.

The number of space outputs is the difference between the contents of the position counter 2 and the output code number counter 3 obtained by the subtraction circuit 4, and the value is "3".

After the space is output, the format symbol ":" is output in step 9.

Here, the reset signal is sent from the output control circuit 1 to the position counter 2 and the output code number counter 3, and these counters are reset.

If the Korean character before the format symbol is shorter than the byte length of the longest word, the space code is included after the byte position of the ":" symbol in memory and the last byte position of the Korean character. Format code is read.

In this case, a step for processing the space information read from the memory is entered between steps 4 and 5.

In step 10, since the code stored in the byte position 6 is a normal character, the subtraction result is "0", and no space signal is generated.

In this way, the characters after step 10 are output. By outputting the example of the data in the memory shown in Fig. 3 by the above operation, the output position control character ": "

In Fig. 3 and Fig. 4, " △ " denotes a space printed (displayed) as space information, and " " denotes a space generated by the space output circuit 5. In Figs.

In the case where the present invention is not implemented, in the case of outputting in the format shown in FIG. 4, it is necessary to store the extra space information on the memory as shown in FIG. 5, and the length of data is different for each row.

Although the above embodiment of the present invention has shown an example of control by hardware, when the output control is realized by a micro program using a memory and a calculation circuit, all of the operations described above may be implemented by a program.

Since it is the structure as demonstrated above, in this invention, the following effects can be acquired.

(1) Since space information for position matching of format symbols for Korean characters is generated in the space output circuit without storing extra memory in memory, memory capacity decreases and changes in output position due to the phoneme structure of Korean characters can be considered. no need.

(2) Since the output position is managed by the byte position, data can be made constant.
