Abstract

PURPOSE:To print out rapidly and easily and display Arabic characters by inputting both Arabic alphabets and phonetic symbols through a keyboard input part and displaying and printing out these characters and symbols on a CRT display part. CONSTITUTION:When an Arabic consonant is inputted from the keyboard input part 1, the consonant is stored in a text memory 5 as an Arabic code and data of the character code are read out from a ROM3. Then, a display position is determined and the data are displayed on the prescribed position of the CRT display part 7 by an Arabic character generator 6. If the succeeding input to the input part 1 is a consonant, the display starting point is changed and the consonant is continuously displayed on the prescribed position next to the preceding display consonant. In case of a vowel, data corresponding to the character code are read out and displayed. Consequently, Arabic characters such as the Koran which requires the description of phonetic symbols can be printed out and displayed rapidly and easily.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a word processor method for Arabic, and in particular, the present invention relates to a word processor method for Arabic, and in particular, it inputs the Arabic alphabet and its phonetic symbols from a keyboard input section, and inputs the Arabic alphabet and its phonetic symbols. The Arabic characters with
This invention relates to an Arabic word processor method in which a sentence is created by displaying it on a cathode ray tube display (ube l1isplay), and the created Arabic sentence with phonetic symbols is output and printed on an ink/ube. It is something.

[Conventional technology]

Currently, the means of printing and displaying Arabic M letters and sentences are printing with movable type, typewriters, or electronic combiners with built-in small-capacity storage devices, which are in line with recent trends in Japan. Similarly, in Middle Eastern countries where this type of Arabic is used, there is a widespread shift from typesetting printing to type printing, or so-called cold typing, in order to improve the efficiency of typesetting display methods. .

[Problem that the invention seeks to solve]

By the way, in this type of Arabic, the alphabet consists of 29 letters, and of these 29 letters, except for the letter called alif, all the other 28 letters are consonants, so each of these has its own meaning. It is read with vowels.

However, in the normal printed representation of Arabic, these vowel symbols, that is, phonetic symbols, are currently not marked with -, except in the Quran, elementary textbooks, reading materials, etc. In order to read sentences that are not written with phonetic symbols, it is necessary to accurately memorize the vowels of each word that makes up the sentence, and also to Even the same word has different meanings depending on how it is pronounced (how the vowel is attached), so the meaning must be understood by gleaning from the words before and after it.

Furthermore, at present, there is no means as fast as a typewriter to print Arabic characters that require phonetic symbols, such as in the above-mentioned Quran and elementary readers. For this reason, printing methods using typesetting are generally used, which is very time-consuming and extremely inefficient.

[Means for solving problems]

In view of this conventional situation, the present invention allows the Arabic alphabet and its phonetic symbols to be input together from the keyboard input section, and displays the Arabic text with the phonetic symbols on the CRT display section. It is also an attempt to provide an Arabic word processor system that outputs data to a printing unit for printing.

〔Example〕

Hereinafter, one embodiment of the Arabic word processor system according to the present invention will be described in detail with reference to FIGS. 1 to 3.

FIG. 1 is a block diagram showing an outline of an Arabic word processor to which this embodiment is applied.

In the embodiment shown in FIG. 1, the symbol l has an Arabic letter key, a phonetic symbol key, and an editing key for these keys, and the Arabic alphabet and its phonetic symbol are edited and outputted as necessary. This is a keyboard input section. 2 is a CPU (Central P) that performs various controls based on signal input from this keyboard input section l.
processing unit (central processing unit), 3 is a ROM in which the operation sequence program for the entire device is written.
(Read 0nly Me+5ary read only memory), 4 is one-to-one with the display dot of CRT, which will be described later.
A display memory 5 stores output signals corresponding to the keyboard input section 1, a text memory 5 stores sentences inputted from the keyboard input section 1 as codes, and a display memory 4 stores the sentences inputted from the keyboard input section l.
Alternatively, it is an Arabic character generator that receives a code output from the text memory 5 and outputs a dot pattern, and these constitute a control section. Further, 7 is a CRT display section for displaying the output signal from this control section, and 8 is a printing section of a dot printer, laser beam printer, etc. for printing the output signal from this control section.
9 is an auxiliary storage device such as a floppy disk for storing sentences.

Next, the operation of the apparatus configuration of this embodiment will be described.

An example of how one Arabic character is displayed on the CR7 display section 7 is shown in FIG. That is, in this Figure 2, since Arabic sentences are basically written and displayed from right to left, the upper right is the origin (0,0).
, one character of the same Arabic character is displayed and printed on a two-dimensional coordinate with the positive X axis pointing leftward and the positive Y axis pointing downward from this origin.
7 A certain point on the display section 7 can be expressed by coordinates (x, y).

Also, in this Figure 2, ■ indicates the display position of Arabic consonants, ■ indicates the display position of the same vowel, and ■ indicates the display position of the consonant ■ and the vowel ■ after a character is displayed. indicates the display position of the next consonant to be displayed, and (STx, 5Ty) is the display start point. For example, if you start writing a sentence from the upper right corner of the CRT7,
Tx=0, RTy=0). Subsequently, D is the maximum value of the vertical display range of one Arabic character, and h
1, h2, d1, d2 are consonants, h3. d
3 is the value determined for each of the above vowels, hl
and h2 determine the upper and lower limits of the consonant, di indicates the character width of the consonant, and d2 is a value indicating the display start point of the vowel when the vowel is added to the consonant. Also, h3 is the value of the vertical display range of the vowel, d3 is the character width of the same vowel, and d4
indicates the interval between consonants and vowels. That is, in this way, the consonant display range is (STx,
STy 10 low hl) and C3Tx+ di, STy+ D
A rectangular part (
The hatched area), and the vowel display range is (STx+d2).

STy + D-hl-d4+h3) and (STx+d2
+d3. It is a rectangular part (the part surrounded by a dotted line) whose diagonal is a straight line connecting STy+El-hl+d4).

In this case, the above-mentioned calculation and setting of the display position of one Arabic character and its control sequence are stored in the ROM 3, and all operations are controlled by the CPU 2.

This operation, in other words, a flowchart of the operation sequence for displaying Arabic consonants and corresponding vowels is shown in FIG.

That is, first, consonants of Arabic letters are input from the keyboard input section 1. At this point, the input character information, that is, the consonant in this case, is stored in the text memory 5 as an Arabic code, and data about this character code hl, h2 . After reading di and determining its display position, the Arabic character generator 6 causes the consonant to be displayed at a predetermined position on the CRT display section 7.

When the next Arabic character input into the keyboard input section l is, for example, a consonant, the display start point (ST!, 5Ty) is changed to (STx+di, 5Ty).
, and in the same sequence as above, this consonant is continuously displayed at the predetermined position next to the previously displayed consonant, and if it is a vowel, data d2. about that character code is displayed. d3. h3 is read out, its display position is determined, and this vowel is similarly displayed at a predetermined position.

Furthermore, the Arabic text displayed on the CRT display section 7 in this manner can be output to the printing section 8 for printing, and can also be stored in the auxiliary storage device 9 if necessary. be.

In the above embodiments, the means for setting each numerical value that determines the display position of each consonant and vowel may be arbitrary, and no matter what kind of setting means is used, it is possible to As long as the display position is uniquely determined, the method of the present invention can be fully applied, and it goes without saying that this method can be applied not only to Arabic but also to word processors of other languages.

〔Effect of the invention〕

As detailed above, according to the method of the present invention, both the Arabic alphabet and its phonetic symbols are input using the keyboard input section, and in this way, the Arabic text with the phonetic symbols is displayed on the CRT display. The display is displayed in the print section, and is also output to the print section for printing, which makes it possible to print Arabic characters that require phonetic symbols, such as in the Koran and elementary readers, compared to the conventional method of displaying them in print. It has superior features such as being faster and easier to print than typesetting printing methods.
