Abstract

PURPOSE:To make form working efficient and to reduce the cost of a printing/ displaying means by using a character generator for storing plural Arabic characters and cldes and alphabetical characters and codes as pattern data. CONSTITUTION:A character generator part is constituted of a character generator 6 and a font memory 7. At the printing of an Arabic character, the generator 6 receives a character code and extracts and outputs character data corresponding to the character code from the memory 7. There are 224 character codes in all and Arabic character codes, alphabetical codes and other codes are included in the character codes. Consequently, these characters and codes can be displayed and printed out mixedly. When the form is to be changed, a proper control code corresponding to the character code out of plural control codes is use as a form conversion code to change the form. Consequently, the form working can be made efficient and the cost of the printing/displaying means can be reduced.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a word processor system for Arabic, and in particular, when printing Arabic characters, it is possible to print not only characters for main text display but also bold characters for headings, etc. By making it possible to freely print multiple Arabic characters as needed, and also by making it possible to mix Arabic and English characters, the typesetting work and even the drafting work are made more efficient. This relates to an Arabic word processor system that aims to achieve this.

[Conventional technology]

At present, the means of displaying Arabic characters and texts in print are printing by movable type, typewriters, or electronic composers with built-in small-capacity storage devices6, and in general, these types of characters are When displaying a text in print, characters of multiple glyphs are used to compose the display page in order to draw the reader's attention and give the strongest possible impression.

[Problem that the invention seeks to solve]

However, conventional Arabic word processors using dot printers are only capable of printing characters of one glyph type. On the other hand, when printing and typesetting a sentence that requires English text to be written in Arabic text, note that this printing method does not have a mixed typesetting function, and Arabic text itself is written from right to left in principle. Contrary to this, English sentences are written from left to right, so the places where English sentences are to be inserted in Arabic sentences should be spaced out by eye in advance, and this spacing should be adjusted accordingly. The method used was to cut and paste separately printed English text into the open space, which was extremely complicated and inefficient.

[Means for solving problems]

In view of this conventional situation, the present invention uses a character generator that stores a plurality of Arabic characters, symbols, English letters, symbols, etc. as pattern data, and stores this character generator on a magnetic disk, etc. All external storage devices can be used to output each time they are used, and not only characters and symbols with multiple glyphs in Arabic scripts, but also English characters and symbols can be output in the same way as they are written in Arabic texts. Enables printing by mixing from right to left, making typesetting work more efficient.

This also aims to reduce the cost of the printing notation means.

〔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 system of the embodiment shown in FIG.
It is a keyboard input unit that has symbol keys, other character keys, symbol keys, and editing keys for these, and edits and outputs these as necessary. Also 2
is a CPU (Central Processor) that performs various controls based on signal input from this keyboard input section 1.
sing Unit central processing unit), 3 is a ROM (Rea) in which the operation sequence program for the entire device is written.
d 0nly Memory Read only memory)
, 4 is a display memory for storing output signals in correspondence with the display dots of the CRT, which will be described later. 5 is a text for storing sentences inputted from the keyboard input section 1 as a code and outputting the same. The memory 6 receives the code output from the text memory 5 and retrieves font data corresponding to the code from the font memory 7 which stores font data of display characters.

This is the display memory 4 mentioned above. Or CR mentioned below
This is a character generator that outputs a dot pattern to the T, and these constitute a control section. Furthermore, 8 is an external storage device such as a floppy disk or a hard disk for storing font data such as various characters, symbols, and numbers stored in the font memory 7, and 9 is a display for displaying output signals from the control section. CR
T display section ('Cathode Ray Tube Di
10 is a printing section, such as a dot printer or a laser beam printer, which similarly prints the output signal from the control section.

Currently, the character codes used in computers including word processors of this type and others are generally standardized to C, and the codes range from 0 to 25.
It can be expressed by 5 25B types of numerical values, of which θ to 31 represent control codes, 32 to 127 represent alphanumeric characters, numbers, and various symbols, and 128 to 255 represent control codes. The current situation is that different formats are adopted internationally. Therefore, in this invention, - for example, the Arabic code is
It shall be divided into 128 categories ranging from 8 to 255.

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

FIG. 2 shows the detailed configuration of the character generator section. That is, this character generator section is composed of the character generator 6 and the font memory 7 as described above, and the character generator 6 receives a character code, reads out font data from the font memory 7, The font memory 7 is internally assigned numbers 32 to 255, each indicating a storage address, and the font data corresponding to each number is transferred. Data is stored at the corresponding address. Figure 3 also shows the contents of the external storage device, in which there are multiple types of font data 35 to 255, each with 224 types as a unit of storage, each of which is assigned a font number. When a font number is specified, font data belonging to ``h'' is read out.

Therefore, when the character generator 6 receives a character code, it extracts character data corresponding to the character code from the font memory 7 and outputs it. As mentioned above, there are 224 types of character codes excluding control codes, which naturally include Arabic character codes, English character codes, other symbols, numerical codes, etc. , it becomes possible to display and print a mixture of these characters, symbols, numbers, etc.

If you want to change the font, set an appropriate one among the control codes θ to 31 as the font conversion code for the character code, and when the character generator 6 receives this font conversion code, The next character code is processed as a font number, and the font data corresponding to the font number is retrieved from the external storage device and stored in addresses 32 to 255 of the font memory 7. In other words, by performing the same operations as above when receiving the character code after operating in this way, you can mix a wide variety of letters, symbols, numbers, etc., including English letters, into an Arabic text. In this way, display and printing can be realized.

In the above embodiment, all font data is transferred from the external storage device to the font memory, but if there is sufficient memory, frequently used portions of the external storage device can be transferred to the font memory. It is also possible to store the words and perform high-speed processing, and this method is of course applicable not only to Arabic but also to word processors for other languages.

〔Effect of the invention〕

- As detailed above, according to the method of the present invention, input from the keyboard input unit is stored in the text memory as a character code, and based on this character code, the corresponding font data is extracted from the font memory of the character generator. is output from the character generator, displayed on the CRT display section, and printed on the print section.When a font conversion request is made, the predetermined font data specified by this font conversion code is output. After taking it out from the external storage device and temporarily storing it in the font memory, it is similarly outputted from the character generator and displayed on the CRT display section,
And since it is printed in the printing section, not only characters and symbols with multiple glyph shapes in Arabic characters, but also English characters,
As for symbols, they can be very quickly and easily mixed from right to left in Arabic text, just like their notation, making it possible not only to display them but also to print them.
This has excellent features such as making it possible to improve the efficiency of typesetting work and, by extension, drafting work.
