Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus having a document editing and formatting function for creating and processing a document having a plurality of character types.

[0002]

2. Description of the Related Art In a document processing apparatus that handles a plurality of character types such as alphabetic characters, numbers, hiragana, katakana, kanji, and Greek characters, and creates and processes a document composed of these character types,
In a system in which the character pitch can be controlled for each character, the character pitch is set for each character type so as to be appropriate when the same character type continues. In this case, the document has the character code, size, starting point coordinates, etc. of each of the constituent characters.
Then, when the created document is displayed on the screen or printed out from the printer, the starting point coordinates of each character are set by the determined character pitch, and the font of the character is expanded with the coordinates as the reference position. .

FIG. 7 is a diagram showing a schematic configuration of a document processing apparatus. Reference numeral 21 is a central processing unit, 22 is a memory, 23 is a printer, 24 is a display, 25 is an input device, and 26 is an external storage device. In such a document processing device, when a character is input from the input device 25 such as a keyboard in the document creation mode, the character is temporarily stored in the memory 22. Then, the display 24 or the printer 23
The characters that are input to and output to the human-readable form. When outputting the input character, the central processing unit 21 sends a character code or character font to the display 24 or the printer 23. further,
The input characters are stored in the external storage device 26 at an appropriate time according to a command from the input device 25.

FIG. 8 is a diagram showing an example of processing by a character display system of a conventional document processing apparatus.

In the conventional document processing apparatus, in the case of displaying characters, when the character code to be displayed is read as shown in FIG. 8, first one character is displayed and then one character position is advanced. The process of reading the next character code is repeated until there is no character code to display. That is, in order to calculate the reference position for displaying the next character, the position for the character pitch of the displayed character is added to the original reference position, and if this position is beyond that line, it is regarded as the end of the line, Set the reference position to the beginning of the next line. And
The next character code is read, and if there is a character to be displayed, the character display is continued.

[0006]

However, in the document processing apparatus as described above, since an appropriate character pitch corresponding to the character type is set for each character, there is no problem when the same character type is lined up. When different character types are lined up, for example, when Chinese characters and alphanumeric characters are lined up, there is a problem that the character pitch becomes inappropriate at the transition of the character type.

If the character pitch is set for each character when different character types are lined up, the character pitch for all other character types must be set, resulting in a large amount of data. Therefore, the work to create the data becomes enormous.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a document processing apparatus capable of adjusting the display and output formats of characters by changing the character type.

[0009]

To this end, the present invention provides a first storage means for storing an input character, a first table for storing a character type and a character corresponding to the character type, and a first table. A second table storing values determined by the correspondence between the character type of the character and the character type of the second character next to the first character, and the character table of the character from the first table. A character type determination means for determining the character type of the first character stored in the first storage means, a second storage means for storing a result of determination by the character type determination means for the character type of the first character, and the first storage. The character type of the second character stored in the means is determined by the character type determination means, and the first character and the first character are determined based on the determination result and the determination result stored in the second storage means. Sentence with the letter 2 It is characterized in that it comprises a character spacing determining means for determining the distance.

Further, the storage means for storing a character including a mixture of Japanese characters and alphanumeric characters, the first character stored in the storage unit and the second character next to the first character are Japanese characters. Or character determining means for determining whether the character is alphanumeric and character spacing determining means for determining the character spacing between the first character and the second character based on the result determined by the character determining means. It is characterized by having.

Further, a storage means for storing characters having different character sizes and a character spacing determined by the correspondence between the character type of the first character and the character type of the second character next to the first character. A table storing adjustment values of the characters and a character interval adjustment for determining an adjustment value of the character interval by drawing the table according to the character type of the first character and the character type of the second character stored in the storage means. Means, and character spacing determining means for determining the character spacing between the first character and the second character based on the character spacing adjustment value determined by the character spacing adjusting means and the character size. It is characterized by doing.

[0012]

In the document processing apparatus of the present invention, the table stores the value determined by the correspondence between the character type of the first character and the character type of the second character next to the first character, and the storage means stores the value. Since the character spacings are determined by determining the stored character types of the first character and the second character, it is possible to set the optimum character pitch for changes in the character types. Therefore,
It is possible to provide an easy-to-read character layout in which the position of the output character is calculated according to the change of the character type.

[0013]

Embodiments will be described below with reference to the drawings.
FIG. 1 is a diagram for explaining an embodiment of a document edit formatting system of a document processing apparatus according to the present invention, FIG. 2 is a diagram for explaining character size information in display and output, and FIG. 3 is a character type table. FIG. 4 is a diagram showing an example of a table in which the increment of the character pitch between the character types is set.

In FIG. 1, 1 is an input unit, 2 is a document creating unit, 3 is a document storage memory, 4 is a character type table, 5 is a character pitch increment setting table, 6 is a pitch adjusting unit, 7 is a character register, and 8 is a character register. Is an output control unit, 9 is a character generator (CG), and 10 is an output unit. Document creation section 2
When a character is input from the input unit 1 having a keyboard or the like, is stored in the document storage memory 3. The pitch adjusting unit 6 determines the character type when outputting the character data stored in the document storage memory 3, and adds the pitch adjustment information according to a preset condition when the character type changes. The character type table 4 is used to determine this character type, the character pitch increase setting table 5 is used to add pitch adjustment information, and the character register 7 is used to detect the character type information immediately before in order to detect a change in the character type. It is a register to hold. The output control unit 8 performs control for outputting the characters input through the pitch adjustment unit 6 to the output unit 10 having a display or a printer, adjusts the character pitch according to the pitch adjustment information, and stores the character font. The character generator (CG) 9 is used to develop a character font from the character code, and the character font is transferred to the output unit 10.

As shown in FIG. 2, the characters handled here are managed using, for example, information on the character spacing W, the character width w, the line spacing H, and the character height h. Then, among these pieces of information, the line spacing H is common to each character, but other information is different for each character (however, h may be common). That is, it will be apparent that in English letters, "a" is different from "l", "W", and also it is different from Kanji. Therefore, for such a character group, the character type table 4
Defines the character type within the character (code) range as shown in FIG. Also, the character pitch increment setting table 5
Sets the adjustment value by combining the previous character type and the next character type as shown in FIG. Here, the adjustment value is a ratio with respect to the character height h.

Next, the flow of processing by the system of the present invention will be described.

FIG. 5 is a diagram for explaining the flow of processing by the document processing apparatus having the document editing and formatting function of the present invention.
FIG. 6 is a diagram showing an output example of a character string.

First, the character code is read, the character type of the read character is checked using the character type table 4 as shown in FIG. 3, and further, the character type is the same as the character type previously displayed and held in the character register 7. Check whether or not. If they are different, the reference position (character pitch) for displaying the characters is corrected using the character pitch increment setting table 5 as shown in FIG. For example, the adjustment value × character size (character height h) in FIG. 4 is added to the reference position. The characters are displayed using the calculated reference position (step ~).

Then, in order to calculate the reference position for displaying the next character, the character pitch of the displayed character is added to the original reference position. If this position is beyond the line, it is regarded as the end of the line, and the reference position is set to the beginning of the next line (step ~).

Then, the next character code is read, and if there is a character to be displayed, the character display is continued (step, →→).

FIG. 6 shows an example of printing by the conventional method, and FIG. 6 shows an example of printing by applying the method of the present invention thereto. Comparing the two, the former has a good balance between the kana and the kanji and the interval between the alphabets, but the gap between the kana and the alphabet seems narrow and unbalanced. It can be seen that the spacing is improved because the character pitch such as the diagonal line is corrected between.

The present invention is not limited to the above embodiment, but various modifications can be made. For example, in the above-described embodiment, the display in horizontal writing has been described, but the same can be applied to the case of vertical writing. Also, I explained the method of controlling the reference position to output characters in the system,
When the space is opened, the character code of the actual space may be generated. By doing so, an appropriate space can be opened even when files are transferred to a system that does not incorporate the control method of the present invention and displayed and output.

Further, also in the case of controlling the line end alignment called justify, the control may be performed similarly by setting an adjustment table therefor. Further, although the character pitch is increased, it may be decreased in the above embodiment depending on the combination of character types.

[0024]

As is apparent from the above description, according to the present invention, the character type is determined, the change is detected, and the format of the character output when the character type is changed is adjusted. On the other hand, the optimum character pitch can be set. Therefore, it is possible to provide an easy-to-see character layout in which the position of the output character is calculated according to the change of the character type.
