Description

[Detailed Description of the Invention] The present invention enables information sequentially given to an input section such as a keyboard to be displayed as a character string (text) on a display device or printing device.
In a text processing system, character information input from an input section is formed from two code information, one of which is a character that identifies the original character, as has been conventionally implemented in this type of device. code, and the other code information is punctuation,
Alternatively, the present invention relates to a text information input method in which a prohibition code, such as a closing parenthesis, is used to mean prohibitions in text editing, and both codes are combined to form an input code signal of character information, thereby facilitating determination of prohibitions in text editing processing.

In general, one of the major problems when processing languages and sentences by machines is the problem of Kinsoku processing. In other words, if a punctuation mark, a closing mark, etc. comes at the beginning of a line in a certain sentence, or if an opening mark comes at the end of a line, it is considered a so-called prohibition and must be avoided. In the case of general printed matter, these phenomena are avoided by adjusting the spaces between characters. However, in text processing systems equipped with character displays, etc., which are used as terminals for computers and various information processing systems, it is extremely difficult to adjust the space between characters due to limitations in the display section, printing section, etc. Therefore, various prohibition handling methods have been studied for some time. No matter what kind of prohibition processing method is adopted, if the prohibition processing is to be performed automatically, it is first necessary to identify whether the displayed information that makes up the sentence contains characters (including symbols) that violate the prohibition. It becomes necessary.

Conventionally, as a method for identifying such prohibitions in sentence structure, codes of characters that conflict with the prohibitions of more than 10 types are registered in advance, and the character information given from the input section is registered in character codes that come into contact with the above-mentioned registered prohibitions. It was compared to see if they matched or not. According to such conventional methods, each input character code must be compared with 10 or more types of prohibited character codes, and it is difficult to perform this identification using either hardware or software. There were also problems in terms of structure and time required.

FIG. 1 is a block diagram showing a conventional text processing system as described above, in which 1 is an input section such as a keyboard, 2 is a control section that controls the entire system, 3 is a display section, 4 is a character pattern generator, and 5 is a control section that controls the entire system. is the printing section, 6
7 is a temporary memory that temporarily stores the input character string (sentence), 7 is the character code input from the input section,
8 to 12 are bus lines that connect various parts of the system. In such a text processing system, the character code 7 input from the input unit 1 is compared with the prohibition code registered in advance in the control unit 2 for each input character code, and is sequentially stored in the temporary memory 6 to create a character string (sentence). ). Further, the control section 2 reads character patterns corresponding to the character code 7 from the character pattern generator 4 and displays these character patterns on the display section 3. By the way, the operator is using display section 3.
Look at the text displayed on the display, give instructions from the display coordinate pointing device such as a light pen or tablet (not shown), or the input unit 1, and reconstruct the text on the display to produce the desired text. obtain. This reconfiguration is performed by the control unit 2 based on instructions from the coordinate indicating position device or the input unit. Specifically, the temporary memory 6 is rewritten and the character pattern instructed from the character pattern generator 4 is changed accordingly. This is done by reading and rewriting the display device 3. Even if the display device 3 displays a display that corresponds to the input information in this reconfigured state,
In terms of writing conventions, it does not necessarily mean that the style is satisfactory. That is, situations often occur in which inappropriate character information is displayed at the beginning or end of a sentence, or blanks appear in the rewritten portion. In such a situation, the control unit 2 needs to edit the text by closing blanks or performing prohibition processing, and the control unit 2 checks each character code in the temporary memory 6, closes blanks, and edits the text at the end of the line, For characters that appear at the beginning of a line, it is necessary to check whether the character code violates the prohibition and take appropriate measures such as increasing or decreasing the number of characters per line by one. At this time, in order to detect characters that violate the prohibited rules, it is necessary to sequentially check the 10 or more prohibited characters that have been registered in advance, which increases the number of program steps, and when new prohibited characters are added. The drawback was that the program had to be rewritten every time.

The present invention eliminates the drawbacks of the conventional method described above, and the character code input from the input section is changed from 2 to 2 in advance.
Divided into two parts, one code part has a character code in the conventional sense, and the other newly added part has a character code in the conventional sense.
The present invention will now be described in detail by way of examples, using a text information input method in which each code section is input with a code indicating whether the character violates a prohibition.

In the present invention, for example, character information in hiragana or katakana is inputted from a key input unit, the kana information is displayed on the display device, and the text is displayed, and this kana information surface is indicated by a coordinate indicating position device. The kanji information corresponding to the designated kana information is read out from the comparison table provided in advance for kana-kanji conversion in the storage device, and the appropriate kanji is selected from the read kanji information and displayed on the display device. It is applied to text processing systems such as electronic Japanese typewriters that rewrite the displayed kana information into kanji.

FIG. 2 is a block diagram showing a text processing system embodying the present invention. Reference numeral 21 denotes an input section for inputting character information such as kana, numbers, alphanumeric characters, punctuation marks, parentheses, etc., and various control information.
The input command given to is introduced into the control section 22. Here, the character information (including symbols such as punctuation marks and parentheses) given to the input section 21 is converted into unique code information 27 corresponding to each character and transferred to the control section 22. The information 27 formed by the operation is divided into two parts depending on the content of the information that the code means as shown in the figure. For example, as shown in Fig.
When expressed using a 16-bit code, the 13 bits from the 3rd bit to the 15th bit are used as a character code to identify what kind of character information the input character is, as in the conventional method. 33
is written, and for the remaining three bits from the 0th bit to the 2nd bit, a prohibition code 34 indicating whether or not the character information written in the character code violates the prohibitions in text editing is written. As described above, character code 3 is input by operating the input section 21.
Code information 2 that is a combination of 3 and Kinoku code 34
7 is formed by the input section 21 and transferred to the control section 22. The control unit 22 determines whether the content written in the prohibition code 34 of the input code information corresponds to prohibition processing according to a program installed in advance, and executes a predetermined process based on the determination result. In addition to controlling the text processing system as a whole, the text processing system is configured with a function to control the text processing system as a whole, and is connected to each element constituting the text processing system by bus lines 28 to 31. 23 is a display device having the capacity necessary to display a plurality of text information based on the information given from the control unit 22, and the display content can be changed from the outside using a coordinate indicating position device and an input unit. It is provided. The display device 23
What kind of pattern is displayed is determined by applying the code information 27 from the control unit 22 to the character pattern generator 24, and determining the character pattern information corresponding to the character written in the character code 33 of the code information 27. The information is read out and applied to the display device 23, and the display is driven to display a predetermined character pattern at a predetermined address on the display surface. At the stage when the character pattern is displayed on the display device 23, the control unit 22 has already determined whether or not the input character information corresponds to prohibition processing. The built-in processing function handles prohibition as appropriate.

Reference numeral 25 denotes a printing section which operates according to a printing command provided in the input section 21, and the contents displayed on the display device 23 are transferred via the control section 22 and printed on the recording paper surface.

Reference numeral 26 denotes a temporary storage device connected to the control section 22 via the bus line 32. The temporary storage device 26 serves to temporarily store the input information given from the input section 21 via the control section 22. Display device 2
3 is provided with a sufficient storage capacity corresponding to the capacity of text information displayed simultaneously. The temporary storage device 26 is provided with a character code storage area 35 and a prohibited code storage area 36 in correspondence with the fact that the input code information 27 given from the input unit 21 is composed of a character code 33 and a prohibited code 34,
Code information is sequentially stored by operating the input unit 21. The contents stored in the temporary storage device 26 are rewritten in the process in which the operator edits the contents displayed on the display device 23 by reconfiguring the contents. That is, use a light pen or the like to specify x and y coordinates on the display device 23 on which the input information is displayed, and then operate the information that you want to input from the input section or the like in place of the content that was displayed before the instruction. The information is sent to the control unit 22 as code information including a prohibition code and a character code.
The new characters are introduced into the system, are controlled by the control unit 22 based on prohibition judgments, etc., are transferred to the coordinates x and y of the display device 23, and the new characters are displayed in place of the old characters. In addition, the newly introduced code information is stored in the control unit 22.
Under the control of , the character information stored in the corresponding coordinates of the temporary memory 26 is also rewritten. As a method for determining the prohibited code in the above code information, it is carried out by a program installed in the control section 22. As shown in FIG. 4, the character code 41 and The prohibition code 42 is stored, the prohibition code 42 in particular is decoded by a decoder 43, and whether or not the input information corresponds to prohibition processing is inputted to the control unit 22a via the bus line, and the input signal is used to perform the above embodiment. It can also be configured by controlling a display device or the like in the same way.

The present invention is not limited to only determining the above-mentioned prohibition processing, but is also applicable to displaying characters such as voiced and half-voiced marks, and can be implemented in text processing systems in terminals other than electronic Japanese typewriters.

As described above, when input character information is converted into code information as in the present invention, a character code part that serves to distinguish the original characters from the code information and a prohibition code that distinguishes whether the input character information corresponds to prohibition processing or not. By combining and forming the prohibition code section, the information written in the prohibition code section is only judged, and there is no need to match the prohibition code registered for each input character code one by one as in the conventional method, and the prohibition code in the text editing process can be checked. By simplifying the number of program steps for processing and shortening the required time, it is possible to increase the speed and efficiency of text processing.
