Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a document creation device capable of word wraparound by regarding an external character as one of characters.

[Technical Background of the Invention and its Problems] When a document creation device first appeared in the world, it was only used in companies and offices, but nowadays, document creation devices for individuals have also appeared, and general household Has begun to penetrate. However, most conventional document writing devices are for Japanese or English, and if you want to use a language other than English such as German, you have to purchase a very expensive device dedicated for it or pay a high price. , A low-priced document creation device with a word wraparound function that can be used for English sentences, for example, for German sentences, without installing a ROM for such a character generator and modifying the device. The appearance of was waiting.

[Object of the Invention] The present invention provides a document creation apparatus that can be used in languages other than English by registering character patterns other than alphanumeric symbols as external characters, and that can be word-wrapped even when those external characters are used. To provide.

[Outline of the Invention] The present invention provides a document creating apparatus that includes a display unit for displaying a created document and the like, and is capable of using external characters that are full-width characters created by registering a pattern for a certain code input in advance. Confirming means for confirming that the instruction performed is a word wrap around instruction, and designation means for designating predetermined code information for word wrapping around the following characters in advance in the alphanumeric symbol of the external character or full-width character, When a word wrap around command is confirmed by the confirmation means, it is determined whether the code information at the end of the line of the document displayed on the display means is an alphanumeric symbol of the external character or full-width character other than the predetermined code information. However, if it is an alphanumeric symbol of the external character or full-width character other than the predetermined code information, the immediately preceding code information is the predetermined code information. It is determined whether it is an external character other than the code information or an alphanumeric symbol of full-width characters, and the determination means repeats the above operation for each character, and the code information determined by the determination means is the predetermined code information. A document preparation apparatus comprising: a line-carrying-down means for sequentially advancing the subsequent characters when it is determined to be an alphanumeric symbol or a space of an external character or a full-width character and a system space.

Embodiments of the Invention The present invention will be described below with reference to the drawings.

First, with reference to FIG. 1, the configuration of an embodiment according to the present invention will be described. The microprocessor 10 is connected to the system bus 30 and controls the entire system. RAM1
2 is also connected to the system bus 30 and is for storing data and programs. As shown in FIG.
The memory area is divided into a document area 41, a prohibited extension document area 42, a line modification information area 43, a system work area 44, and the like. The document area 41 is an area for storing an input alphanumeric symbol or the external character, and is an extended document area for prohibition.
42 is not used unless prohibited. When the prohibition process is performed, a prohibition image symbol must be assigned, and more document area is required than usual, and therefore, it is used when the prohibition process is performed. Area for line decoration information 43
Is used when line modification such as white blank is performed. A program or the like is stored in the system work area 44, and for example, the number of characters, that is, the number of digits, per line for formatting is also stored in this area. The control ROM 14 stores a special program that is not stored in the RAM 12 and that requires high-speed processing, such as a program relating to formatting. The pattern generation ROM 22 is also connected to the system bus 30, and when data is designated, it generates a pattern corresponding to the data. A keyboard 17 is connected to the system bus 30 via a keyboard interface 16, so that the keyboard interface 16 outputs instructions and data input from the keyboard 17 onto the system bus 30. Similar to the keyboard, the external storage device 20 and the display device 25 are connected to the system bus 30 via the external storage device interface 19 and the display control device 24, respectively. The external storage device interface 19 includes at least one external storage device.
20 can be controlled, and input / output of data, programs, etc. with the internal storage device. The display VRAM 23 is also connected to the system bus 30 and stores the data from the pattern generation ROM 22. The display control device 24 reads the data from the display VRAM 23, starts a document on the display device 25, and displays necessary information. An external communication interface 27 connected to the system bus 30 is provided as necessary, and outputs an instruction and data input from the outside onto the system bus 30 or outputs data or the like to the outside.

Next, the operation of the word wrap around process will be described with reference to FIGS. 3 (a), 3 (b) and FIG. FIG. 3 (a) is an example in which a German document is input. In this example the format is set to 12
Data such as alphanumeric symbols or the above-mentioned external characters input from 17 are stored in the document area 41 of the RAM 12 in a coded form. At this time, storage is performed in order from the beginning of the empty portion of the document area. Here, for example, a blank on the second line and the fifth digit means that a space symbol has been entered, and a space on the fourth line and the fourth and subsequent columns is entered. Is a system pace symbol generated by the document creator to fill the 12th digit after the period to match the number of digits in the format. The u in the 12th digit of the second line is a character that is not found in English. Therefore, by registering this character as an external character in advance, for example, it is stored in the external storage device 20 and is read when necessary. In this way, the German document is input. Usually, the target of word wraparound processing was half-width alphanumeric symbols. On the other hand, external characters were full-width and could not be targeted for word wraparound. Therefore, in this embodiment, a ROM 22 for generating a pattern for alphanumeric symbols for full-width alphanumeric symbols is prepared. Therefore, the alphanumeric characters or the external characters are stored in the document area in full width.

Next, the processing when a word wrap around instruction is issued for this document will be described with reference to FIG. First, the value of the row variable is set to 1, and the value of the digit variable is set to 12, that is, the value of the format (S1, S2). This means checking the alphanumeric characters in the 12th digit on the first line or the above-mentioned external characters. Therefore, one alphanumeric symbol or one of the above-mentioned external characters designated by this line variable and digit variable is read (S3). In the example shown in FIG. 3A, there is a space. Next, it is determined whether the read alphanumeric symbol or the external character is the alphanumeric symbol requiring the word wraparound or the external character, for example, space or system space (S4). If the read alphanumeric symbol or the external character is space or system space, step S9 is executed, and if not, step S5 is executed. In this case, it is a space, so step S9
To execute. In step S9, (the number of digits in the setting format)-(the number of digits in the digit variable) is calculated, and spaces are generated by the number corresponding to the answer. In this case, the value of the digit variable is 12, and the number of digits in the format is 12, so the answer is 0. Therefore, 0 spaces are generated. That is, do nothing. This completes the word wraparound on the first line and adds 1 to the line variable (S10). Here, it is checked whether the value of the row variable exceeds the maximum number of rows (S11). In this case, the value of the row variable is 2, and the maximum number of rows is 4. Therefore, the document creation device executes step S2. That is, 2
We will look up the 12th digit of the line. The alphanumeric symbol or the external character designated here is as shown in FIG. 3 (a), and since the alphanumeric symbol or the external character that requires word wraparound is not the space or system space, step S5 is executed. To be done. Since is not an alphanumeric symbol but a character registered as an external character, the process proceeds to step S7. And the digit variable is subtracted by 1. That is, the value of the digit variable is 11 here. Since the value of the digit variable is not zero, step S3 is executed again (S8). The second line of FIG. 3 (a)
Since it is f in the 11th digit and is not the space or the system space as described above, the process proceeds to step S6. Since f is an alphanumeric symbol, the process proceeds to step S7, and the digit variable is subtracted by 1. Here, the value of the digit variable is 10. If the alphanumeric symbol or the external character being examined at this time is, for example, a kana character, step 10 is executed. Since the digit variable is not zero, step S3 is executed again (S8). Third
Since the tenth digit on the second line in FIG. 10A is an alphanumeric symbol for stopping the search operation or the external character, for example, a space, step S9 is executed. In step S9, the calculation of 12-10 is performed, the answer of 2 is obtained, and two spaces are inserted in the 10th digit of the second line. This is shown from the 10th digit to the 12th digit in the second line of FIG. 3 (b). At this time, the subsequent document is shifted backward by two digits. Next, it is checked whether the maximum number of lines is exceeded, and if not, the next line is checked. Here, the alphanumeric symbol in the 3rd line and 12th digit or the above-mentioned external character is taken in. The letter e is shown in the third line, 12th column of FIG. 3 (a), but since two spaces have been inserted by the word wraparound process in the previous line, it is actually the letter s. There is. Therefore, step S5-S described above
Repeat 8 and insert one space. The result is shown in FIG. 3, line 3, column 12. In this way, the word wrap around process is executed. Here, in step S4, it is determined that the imported alphanumeric character or the external character is system space or space. Alternatively, the external character may be designated. For example, if you specify German, Kanji, and Kana characters as external characters, and specify the Kanji, Kana characters, system space, and space among the registered external characters as the characters for word wraparound after that, the characters will become Japanese. It is possible to perform word wrap for English / German sentences and not word wrap for Japanese documents even in a mixed English / German sentence.
Similarly, it is possible to arbitrarily pre-designate an alphanumeric symbol or the above-mentioned external character for which the space insertion operation is not to be performed, and to make a judgment in step S6. In this way, the alphanumeric symbol requiring the word wraparound or the external character and the alphanumeric symbol stopping the search operation or the external character may be the same. Also, when the kana character is used, the search operation is stopped and the process proceeds to the next line, but this can also be selected from the alphanumeric symbols or the external character.

[Effects of the Invention] In the document creation device according to the present invention, since the size of the alphanumeric symbol and the size of the external character are the same, that is, since they are both full-width characters, the external character can be the target of the word wraparound. If this is supported by the circuit means, the word wrap around process can be executed.
Further, if a pattern of characters and symbols other than English is created with external characters, it can be used not only as an English document creating device but also as a document creating device for foreign languages other than English.
