Abstract

PURPOSE:To record a large quantity of Japanese word text data except ruled line characters with use of an output file having limited capacity, by compressing only the ruled line character string data using many types of same characters among those data containing many types of characters like the Japanese word text data, etc. CONSTITUTION:Instructions are given from a keyboard 1 for input, editing and output (to an output file) of the Japanese word text data. A memory buffer 2 stores temporarily data supplied from the keyboard 1. A comparison part 3 compares a certain ruled line character data extracted out of the input Japa nese word text data with other data for extraction of the same ruled line characters and also decides whether the character string data should be com pressed or not. A file output part 4 outputs the input data to an output file. Then an editing part 5 performs editing jobs to display the input Japanese word text data on a display part 6 and to output said text data to the output file and also compresses the character string data. Thus it is possible to output a large quantity of data to a file having limited capacity.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to text data editing for Japanese language processing, and in particular, in text data that uses many ruled line character data in addition to character data including kanji, This invention relates to a Japanese text data editing method that compresses and outputs only ruled line character strings, which are often composed of repeats, by column length encoding.

(Prior art) Conventionally, this type of Japanese text data editing method stores ruled line character data input from the keyboard in an input buffer like other character data, displays it sequentially, and then outputs it to an output file. It was outputting.

(Problems to be Solved by the Invention) The conventional Japanese text data editing method described above outputs ruled line character data, which is often composed of repetitions of the same character type, to an output file as is. Therefore, if there are many repetitions of the same character in the ruled line character data, much of the output file will be occupied by the same character data, resulting in the problem that a large amount of data will not be output to a file with limited capacity. .

(Means for Solving the Problems) In order to solve the above-mentioned problems, the Japanese text data editing method provided by the present invention is to display consecutive identical character strings of a predetermined number or more, It is characterized in that it performs data compression to encode the number of consecutive characters and then outputs it to a file. To achieve this, the present invention provides means for inputting Japanese text data;
means for storing Japanese text data input by the input means; means for extracting a predetermined number or more of consecutive identical character strings from the Japanese text data stored in the storage means; means for editing Japanese text data by compressing the same character string, means for displaying the Japanese text data edited by the editing means on a display, and means for outputting the Japanese text data to a file. It is equipped with

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a method for editing Japanese text data according to an embodiment of the present invention.

The keyboard 1 is used to input Japanese text data, edit it, and give instructions for outputting it to an output file. A memory buffer 2 temporarily stores data input from the keyboard 1. The comparison unit 3 compares certain ruled line character data with other data from the input Japanese text data, extracts the same ruled line characters, or determines whether or not to perform character string data compression processing. do. The file output section 4 outputs the input data to an output file, and the editing section 5
performs editing when displaying input Japanese text data on the display unit 6, editing when outputting to an output file, and data compression processing of character strings.

The display unit 6 displays the input data.

FIG. 2 is a diagram showing the structure of compressed data obtained by compressing a ruled line character string according to this embodiment, in which the character string is encoded by string length.

Cs is a data compression instruction code that indicates that the three encoded characters (Cs + C11 and Cc) have been subjected to data compression processing, C5 is the code of the ruled line character that has been subjected to data compression processing, and CC is the code for data compression processing. Indicates the number of ruled line characters.

Next, the operation of this embodiment will be explained in detail.

FIG. 3 is a flowchart showing the operation of character string data compression in this embodiment.

In the initial state, a ruled line character counter for identifying the first ruled line character and a character counter for adding up the number of identical ruled line characters are set to "0" (steps 11 and 12). When Japanese text data is input from the keyboard 1, this data is temporarily stored in the memory buffer 2 and displayed on the screen by the display section 6 (step 13). In addition, the comparison unit 3 determines whether or not the input of the data is completed, and if the input is completed, the process is terminated in step 1.
4 and Step 15) 6 It is determined whether the Japanese text data entered manually is a ruled line character or not. If it is not a ruled line character, the process returns to Step 11 without executing the data compression process of the character string (Step 16).

If the magazine dex data is a ruled line character, it is determined whether or not this ruled line character is the first ruled line character based on whether or not the ruled line character counter is 0'' (step 17). ). In the case of the first ruled line character, "1" is added to the ruled line character counter in step 18, the code of this ruled line character is stored in the comparison section 3 in step 19, and the process returns to step 13 to write the next Japanese text data. This is the input process.

Next, when the input Japanese text data is a ruled line character, in order to detect whether this second ruled line character is the same ruled line character as the first ruled line character, the said ruled line character is stored in the comparing section 3. A match with the code is verified (step 20). If fl's first ruled line character and second ruled line character do not match, the process proceeds to step 19, where the code of the second ruled line character is stored in the comparison unit 3, This is the third input process for Japanese text data. If the first ruled line character and the second ruled line character match, “1” is added to the character counter.
are added (step 21). Next, when a character string is data compressed and encoded into string length encoders, three characters are required as shown in FIG. Therefore, the number of characters in the same ruled line is determined in step 22, and if the number is 3 or less, the process returns to step 13 without performing data compression processing on the character string. Data compression processing is performed only when the number of characters on the same ruled line is four or more (step 23).

Furthermore, if Japanese text data other than the ruled line characters immediately follows the ruled line character string, it is output following the column length encoded data. The Japanese text data including the ruled line character strings subjected to data compression processing is outputted to an output file by the file output unit 4.

(Effects of the Invention) As explained above, the present invention compresses only ruled line character string data that uses many of the same character types among data with many character types such as Japanese text data. This has the effect of being able to record a large amount of Japanese text data other than ruled line characters in an output file with a large capacity.
