Reference numeral 5 is a print data generator, 16 is an inter-character space generator, 17 is a character pattern generator, 18 is a print buffer, and 19 is a printer. When the character spacing of the document input to the document data 11 is designated or changed, the line format designation device 12 designates the character spacing on a line-by-line basis. The designated format is stored in the document data 11. When printing the document thus created, first, the character reading device 13 reads out one line of data from the document data 11. Next, the character spacing recognition device 14 reads and recognizes the character spacing from the document data 11.

Next, the print data generator 15 generates a character pattern for each character from the character pattern generator 17 based on the previously read character data for one line.
It is stored in the print buffer 18. At the same time, the inter-character space generating device 16 creates a space after the character pattern based on the character spacing data and creates print data in the print buffer 18. When the creation of the print image data for one line is completed, the printing device 19 prints the data for one line. Although a general printing apparatus that prints on a line-by-line basis has been described below, the method of creating a print image is similar for a page printer that prints on a page-by-page basis. Line format (or line decoration) for character spacing information
The difference from the present invention is that it is stored as.
The present invention does not specify line by line.

FIG. 6 is a block diagram showing another example of a conventional document processing apparatus.

The parts that operate are given the same reference numerals. Document data 1
When designating a part of the document input in 1, the logo designating device 22 designates a character string for designating the logo. Then, in the document, a control symbol indicating that the specified character string is sandwiched and the logo is specified is displayed. Table 1 shows an example.

[0005]

[Table 1]

When printing the document thus created,
First, the character reading device 13 causes the document data 1 to 1
Read the data for a row. Next, the print data generator 1 recognizes character data character by character from the read data.
5, the character pattern generator 17 generates a character pattern and stores it in the print buffer 18. Based on the character spacing information read by the character spacing recognition device 24, a space is created after the character pattern by the inter-character space generator 16 to create print data in the print buffer 18.

Character spacing and logo control code recognition device 24
When the control code indicating the range of the logo is recognized, the character spacing is changed to 0. After that, print data is created without a character space after the character until the control code indicating the end of the logo is recognized. When the control code for ending the logo is recognized, the character spacing before the logo is specified is restored, and print data creation continues. When the creation of the print image data for one line is completed, the printing device 19 prints the data for one line. As described above, in the conventional technique, the character spacing of the designated character string is set to 0 (or a value close to it), whereas the present invention sets the character spacing at any position in the line. Is to change to.

FIG. 7 is a block diagram showing still another example of a conventional document processing apparatus. In the figure, 32 is an even allocation designating device, and 34 is
Is a character spacing recognition device (equal allocation recognition device).
The parts having the same functions as those in FIG.
When a part of the document input to the document data 11 is to be specified for equal allocation, a character string to be specified for even allocation is specified by the even allocation specifying device 32. Then, in the document, a control symbol indicating that the designated character string is sandwiched and the even allocation is designated is displayed. Table 2 shows an example.

[0009]

[Table 2]

When printing the document thus created,
First, the character reading device 13 causes the document data 1 to 1
Read the data for a row. Next, the print data generator 1 recognizes character data character by character from the read data.
5, the character pattern generator 17 generates a character pattern and stores it in the print buffer 18. Based on the character spacing information read by the character spacing recognition device 34, a space is created after the character pattern by the inter-character space generation device 16 to create print data in the print buffer 18.

When the control code indicating the range of uniform allocation is recognized by the character spacing and uniform allocation control code recognizing device 34, the number of characters up to the control code at the end of uniform allocation is recognized, and the character interval corresponding to the number of characters is calculated. Within the even allocation, spaces are placed after the character pattern according to the calculated character spacing. After that, the character spacing before the uniform allocation is specified is returned, and the creation of print data is continued. When the creation of the print image data for one line is completed, the printing device 19
Prints one line of data. As described above, in the conventional technique, the designated character string is evenly allocated to the designated width, whereas the present invention changes the character spacing at any position in the line. Is.

A known document describing a conventional document processing apparatus is, for example, JP-A-61-286893. This publication discloses a line decoration designating means for designating character decoration on a line-by-line basis of an input document, and a display means for selectively displaying a selection screen for character spacing when the line decoration designating means specifies line decoration. The input means for selecting the character spacing from the selection screen, the line attribute storage means for storing the selection information of the character spacing input by the input means in association with the line of the document, and the line attribute storage means A display screen selecting means for optionally displaying the stored selection information of the character spacing is provided, and the character spacing can be set in units of the lines of the input document. This makes it possible to easily create a variety of documents in units of.

[0013]

In the conventional document processing apparatus, as described in the above-mentioned Japanese Patent Laid-Open No. 61-286893, the character spacing in a sentence can only be changed line by line. As a method of changing the character spacing in the middle of a line, there are logo designation and even assignment.
In the case of logos, the character spacing is fixed at 0, and in even allocation, the character spacing is automatically determined. Therefore, it was not possible to make delicate adjustments. In addition, when designating a logo or even layout, control symbols are often used to indicate the range, so that the uniform layout can only widen the character spacing and cannot print with narrowing. In addition, it was not possible to specify the character spacing to be negative. For this reason, when the number of characters in one line cannot be input on a certain sheet, the character size must be reduced to print.

The present invention has been made in view of such a situation, and by enabling the character spacing to be specified at an arbitrary position, it is possible to perform a fine adjustment that was not possible in the conventional line unit. Also, changing only the character spacing between the character at the cursor position and the character before it, changing only the character spacing between the character at the cursor position and the character after it, and character spacing in any range within the sentence It is an object of the present invention to provide a document processing device which can change only the characters, and can specify the character spacing to be negative.

[0015]

In order to solve the above problems, the present invention provides (1) changing means for designating or changing the character spacing of a document input to document data, and one line from the document data. The character reading means for reading the character data, the character spacing recognizing means for reading the character spacing within the format from the document data storing the specified character spacing data, and the read character data for one line. In a document processing apparatus having character pattern generating means for generating a character pattern for each character and character space generating means for spacing a space in the character pattern based on the character spacing data, the changing means includes a text string. Is a character spacing designating unit capable of designating and changing the character spacing of the following text string at the beginning of any of the characters, and determining and outputting the arbitrary character spacing in the sentence, or ( ) Changing means for designating or changing the character spacing of the document input to the document data, character reading means for reading character data of one line from the document data, and document data storing the designated character spacing data. , Character spacing recognition means for reading the character spacing in the format, and 1 based on the read character data for one line
In a document processing device having a character pattern generating means for generating a character pattern for each character and an inter-character space generating means for leaving a space in the character pattern based on the character spacing data, the changing means may be any of the text strings. It is a character spacing designating unit that can designate and change the character spacing of the following text string at the beginning of the character, and determine and output the character spacing with the preceding character of the designated character, or (3) input the document data. The character spacing within the format is determined from the changing means for designating or changing the character spacing of the document, the character reading means for reading one line of character data from the document data, and the document data storing the designated character spacing data. Character spacing recognition means for reading, character pattern generation means for generating a character pattern for each character based on the read character data for one line, In a document processing device having intercharacter space generating means for leaving a space in a character pattern based on the character spacing data, the changing means specifies a character spacing of a subsequent text string at an arbitrary character start of the text string, It is a changeable character spacing designating means, and determines and outputs the character spacing between the designated character and the succeeding character, or (4)
From the document data that stores the specified character interval data, the changing unit that specifies or changes the character interval of the document input to the document data, the character reading unit that reads the character data of one line from the document data, Character spacing recognition means for reading the character spacing in the format, and the read 1
In a document processing device having a character pattern generating means for generating a character pattern for each character based on character data of lines and an inter-character space generating means for leaving a space in the character pattern based on the character spacing data, The changing means is a character spacing designating means capable of designating and changing the character spacing of subsequent text strings at the beginning of any character of the text string, and changing the character spacing of the area surrounded by the preceding character and the following character to the character spacing before and after that. (5) In any one of (1) to (4), a negative value can be set and changed as a set value of the character spacing. It was done.

[0016]

The document processing apparatus of the present invention having the above structure is
(1) Since the character spacing in subsequent sentences can be set and changed at the beginning of any character in the sentence string, any character spacing in the sentence can be determined. Information indicating the character spacing is stored before the character. (2) Character spacing can be specified at the beginning of any character in the text sequence by setting and changing the character spacing between subsequent text sequences. Then, the information indicating the character spacing from the preceding character is stored before the character.

(3) Since the character spacing between the designated character and the succeeding character can be determined by means of setting and changing the character spacing of the subsequent text string at the beginning of any character in the sentence string, the character spacing can be determined. If you specify an interval, information that indicates the character interval with the next character is stored before that character. (4) By providing a front character spacing designating means as a means for setting and changing the character spacing of a subsequent text string at the beginning of an arbitrary character of the text string, the character spacing of the area surrounded by the front means and the back means is adjusted. Since it is possible to change from the character spacing before and after, if you specify an arbitrary range in the sentence, change the character spacing for the range specified there, and specify the character spacing, the subsequent characters are added to the beginning of the specified range. Information indicating a space is stored, and information that makes the subsequent character space the same value as before the change is stored before the last character in the specified range. (5) Since a negative value can be set as the character spacing setting value in the above (1) to (4) and can be changed, a negative value can be set when each character spacing is specified. It is stored in the character spacing information of.

Embodiments will be described below with reference to the drawings. FIG. 1 is a block diagram for explaining an embodiment (claim 1) of a document processing apparatus according to the present invention. In the figure, 1 is document data, 2 is a character spacing designating device, 3 is a character reading device, and 4 is a character reading device. Is a character spacing recognition device, 5 is a print data generation device,
6 is an inter-character space generator, 7 is a character pattern generator, 8 is a print buffer, and 9 is a printer.

The difference from the conventional structure is that the character spacing is designated by the line format designating apparatus 12 of FIG. 5 in the prior art, whereas it is designated by the character spacing designating apparatus 2 in the present invention. The character spacing designating device 2 has the following designating methods. Change the character spacing between any character in the sentence and the character before it. Change the character spacing between any character in the sentence and the character after it. Change the character spacing in any range in the sentence from the character spacing before and after it. Specify the character spacing change according to the conventional line format. Furthermore, it is possible to specify a negative character spacing for each specification.

The method of designating the character spacing will be described below with reference to FIG. When designating or changing the character spacing of the document input to the document data 1, the character spacing designating device 2
The character spacing is specified by the above method. The specified character spacing data is stored in the document data. When printing the document thus created, first, the character reading device 3 reads out one line of data from the document data 1. Next, the character spacing recognition device 4 reads and recognizes the character spacing in the format from the document data 1.

Next, the print data generator 5 generates a character pattern for each character from the character pattern generator 7 based on the previously read character data for one line and stores it in the print buffer 8. At the same time, the inter-character space generator 6 creates a space after the character pattern based on the character interval data and creates print data in the print buffer 8. When the information indicating the change in the character spacing is found in the one-line data, the character spacing recognizing device 4 recognizes the value, and the character spacing generating device 6 changes the character spacing according to the specified value in accordance with the specification of ,,. Give a command to. When the print image data for one line is created,
The printer 9 prints one line of data. that's all,
Although a general printing apparatus that prints on a line-by-line basis has been described, the method of creating a print image is the same for a page printer that prints on a page-by-page basis.

FIG. 2 is a flow chart for explaining the operation of the document processing apparatus according to the present invention. Hereinafter, each step (S) will be described in order. First, format data is extracted (character size, character spacing, etc.) (S1), and one line of document data is extracted from the document (S2). Next, it is judged whether or not the data has ended (S3), and if it has ended, the processing is ended, and if not ended, it is judged whether or not the character spacing has been changed (S4). If the character spacing is changed, the format character spacing information is changed (S5), and the process returns to step S2. If the document interval is not changed, then one character is extracted from the data for one line (S6), and it is determined whether or not the data for one line is completed (S7). If it is finished, the data in the print buffer is printed (S8), and if it is not finished, then it is determined whether the character spacing is changed (S9).

If the character spacing is changed, the character spacing from the previous character is changed (S10), and the process proceeds to step S15. If the character spacing is not changed, it is then determined whether the character spacing is changed (S11). If the character spacing is changed, only the next character is changed in the character spacing (S12), and the process proceeds to step S15. If the character spacing is not changed, it is then determined whether the character spacing is changed (S13). If the character spacing is changed, the character spacing information is rewritten (S14), and the process returns to step S6.
If the character spacing is not changed, the character pattern is extracted and stored in the print buffer (S15), and a space is provided after the character based on the character spacing information (S16).
Return to 6.

Tables 3 to 5 below show examples of the development of the print image for changing the character spacing. In addition, Table 3 shows claim 2
Table 4 shows a development example of the print image of claim 3, and Table 5 shows a development example of the print image of claim 4, respectively.

[0025]

[Table 3]

[0026]

[Table 4]

[0027]

[Table 5]

Although the designation methods in Tables 3 and 4 are different, the print results are the same. The data may have the following structures. Character spacing between "P" and "stock" is 10 dots,
If the others are 4 dots, the data structure example is as shown in Table 6 below.

[0029]

[Table 6]

An example of the data structure of Table 5 is shown in Table 7 below.
Shown in

[0031]

[Table 7]

An example of developing a print image with a negative character spacing (claim 5) is shown in Table 8 below, and an example of its data structure is shown in Table 9 below.

[0033]

[Table 8]

[0034]

[Table 9]

The following format is conceivable as the control code indicating the character spacing. (1) Change the character spacing only between two characters that sandwich the control code (Tables 10 and 11).

[0036]

[Table 10]

[0037]

[Table 11]

The character spacing between B and C is 10 dots. The character spacing between C and D reverts to the previously set character spacing. (2) Change the character spacing after the control code (Table 12,
13).

[0039]

[Table 12]

[0040]

[Table 13]

The character spacing between A and B and the character spacing between B and C is the previously designated character spacing, and the character spacing between C and D is 10 dots. In addition, the character interval between D and the next character is also 10 dots.

In the present invention, it is assumed that the character spacing data is mixed with the character data. Table 14 below shows the method of displaying the character spacing data on the screen in that case.

[0043]

[Table 14]

When the data shown in Table 10 is displayed, it may be possible to change the character size and the character spacing on the input screen similarly to printing, but it is difficult for a low-cost display device. Therefore, these three characters are not displayed but displayed like ABCD. Then, the character spacing at the cursor position is displayed in the guidance. For example, A and B, B and C
If the character spacing of is 4 and the character spacing of C and D is 10,
When the cursor is at A or B, 4 is displayed in the guidance, and when it is at the positions of C and D, 10 is displayed. Guidance is displayed using one line at the bottom or top of the screen. Table 15 shows a display example.

[0045]

[Table 15]

If the character spacing data is not displayed on the screen but is displayed in the guidance, it is difficult to confirm where the character spacing is changed (though it can be understood by moving the cursor). Therefore, it is advisable to provide a function for searching character spacing data. The search function is generally well known. If you specify to search the character spacing data from the current cursor position toward the beginning or end of the sentence, the codes are compared toward the beginning or end of the sentence according to the specified direction, and as shown in Tables 10 and 12, If you have the code, move the cursor to it. In this way, the position and value for which the character spacing is specified can be confirmed. If the character spacing is specified, the character spacing currently at the cursor is compared with the specified character spacing, and if the values are the same, the character spacing code need not be stored. Does not store.

FIG. 3 is a diagram showing the structure of the print data expansion buffer. Suppose an image is expanded in the print buffer like this. In FIG. 3, 1, 2, 3, 4, 5, ... Show the arrangement of data. Each is 1-byte (8-bit) data. One vertical column corresponds to one vertical column of the printer. The character spacing is not the data to be printed, but indicates how much space is left between characters.
It decides where to store the next character.

FIG. 4 is a diagram showing a state in which character spacing data of the character "A" is stored. If the right end of "A" is, and the character spacing is 4, the next character is stored at the position. If the character spacing is -4, the next character is stored in the position. As described above, according to the present invention, the information for designating the character spacing is stored at an arbitrary position in the sentence based on each designating method, and the print bitmap data is expanded in the print buffer according to the character data or the character spacing information. To do.

[0049]

As is apparent from the above description, the present invention has the following effects. (1) By making it possible to change the character spacing in the middle of a line, it is possible to make fine adjustments that were not possible with conventional line-by-line designation, logos, and even allocation. (2) Only a certain word portion in the sentence can be printed with the character spacing widened or narrowed. (3) By enabling the minus designation of the character spacing, the number of characters that can be input in one line can be increased without reducing the character size. (4) In the case of characters with small letterfaces (characters that are smaller than the outer frame that forms the characters), such as a writing brush, when printing, there will be gaps between the characters even if the character spacing is 0. . In such a case, if there is a negative character spacing, it is possible to print with good balance.
