[Detailed Description of the Invention] [Summary] Regarding a character processing device for uniform layout printing that prints each character in a line of text evenly within an arbitrary section, the start position and end position of the uniform layout are specified. The purpose is to provide a character processing device that realizes evenly spaced printing with strictly equal spacing between characters. In a character processing device for printing, a processing unit includes a character identification means for identifying characters and spaces to be printed within an even allocation range and counting the number of characters and spaces, and calculating a character spacing from the number of characters. a means for calculating the number of spaces between characters, a means for calculating the number of evenly allocated spaces and a number of remaining spaces based on the number of spaces and the number of spaces between characters, a means for calculating the number of evenly allocated spaces and a number of remaining spaces, and a remaining space that calculates the number of remaining dots based on the number of remaining spaces. a dot conversion means, and a remainder dot number allocation means for adding the number of remaining dots to the number of evenly allocated spaces; The print data generating means is provided with a print data generating means for generating a data string in which space data and image data representing a space corresponding to the number of dots obtained by adding dots corresponding to the number of surplus dots to the number of evenly divided dots are added.

[Industrial Field of Application] The present invention relates to a character processing device for uniform layout printing that evenly prints each character in a - line of text within an arbitrary interval.

In recent years, workstations equipped with word processors and character processing functions have become widely used. In such devices, characters and symbols are entered by operating the keyboard while looking at the display device, and various editing operations are performed using various control keys. expressions can be used.

A part of the text created in this way (in the - line) is specified to be evenly distributed and then printed.

However, even if equal allocation is specified, the processing for printing each character is performed character by character, so the total number of spaces available for allocation is the number of character intervals (this is called the character spacing). Although it is sufficient to use an integer multiple of , in reality, it is a multiple that includes decimals, so there is a problem in that it is virtually impossible to print evenly allocated spaces due to the allocation of spaces in units of characters, and a solution to this problem is desired.

[Conventional technology 1 FIG. 9 shows an explanatory diagram of a conventional example.

A, the half-width character “2” is followed by the full-width character “1” as shown in
°゛, followed by the full-width character °°3", the half-width character "4", and the full-width character "5", and the two ends of the sentence with two spaces at the end are specified as the allocation start and end positions. In this case, the number of spaces is 6 half-width spaces (3 full-width spaces), and the number of spaces between characters is 4, so 1.5 half-width spaces are originally allocated between each character. However, in the conventional example, it is processed in character units (a half-width space is treated as a single character in combination with a half-width character), so a half-width space and a half-width character are added after "1" as shown in . "2n", two half-width spaces, a full-width character "3", etc. are printed.

Similarly, full-width characters °“l” to ゛5°° as shown in
If equal allocation is specified when there are 6 spaces for
- 5 spaces (3 half-width spaces) are allocated, but since it is only possible to allocate 3 half-width spaces to the numbers 1 to 5 of full-width characters, the allocation shown in 2. is performed.

[Problem B that the invention attempts to solve]

The present invention relates to the first and second parts of the explanatory diagram of the conventional example described above.

There is a problem with irregular evenly spaced printing as shown in Figure 2 that the printed document looks bad.

In order to print such even layouts, it is possible to express the entire text through image processing, but with devices such as word processors that manually edit characters and then edit them character by character, It is difficult to process it in the form of image data.

Therefore, in order to handle character data as image data for uniform layout printing, it is necessary to provide a huge amount of memory and processing equipment, which increases the cost and is not suitable for practical use.

SUMMARY OF THE INVENTION An object of the present invention is to provide a character processing device that realizes uniform layout printing with strictly equal spacing between characters when the start and end positions of uniform layout are specified.

[Means to solve the problem] FIG. 1 shows the principle configuration diagram of the present invention.

In Figure 1, 1 is the processing unit, 2 is the memory, 3 is the printer, and 10 in the processing unit 1 identifies whether each character in the character data string to be evenly allocated is a character to be printed or a space character. 11 is a character spacing calculation means for calculating the number of character spaces; 12 is an equal space calculation means for dividing the total number of spaces included in the evenly allocated range by the number of character spaces;
13 is a remainder space calculation means for converting the number of remaining spaces generated as a result of the calculation by the equal division space calculation means into the number of dots, and 14 is a remainder space calculation means for dividing the number of remaining dots by the number of character spaces to calculate each character. 15.16 is a means for allocating the number of remaining dots to be allocated between characters (C
H) and a register holding the number of spaces (SP), 17-
Reference numeral 22 represents a register that holds the numerical value obtained in the equal allocation character processing.The present invention is a register that holds the numerical value obtained in the equal allocation character processing. Even though
The remainder is converted into the number of dots, the converted number of dots is divided by the number of character spaces, and the resulting number of dots is sent to the printer in the form of image data, thereby making it possible to print spaces with an arbitrary number of dots. It is.

[Operation] The operation of the principle configuration diagram shown in FIG. 1 will be explained below using the operation principle explanatory diagram shown in FIG. 2.

Text data for which equal allocation is designated by control codes indicating the start and end of equal allocation shown in A in FIG. 2 is inputted using a keyboard (not shown) and stored in the memory 2.

The processing unit 1 extracts character data one character at a time in the range where equal allocation is specified, and uses the character identification means 10 to identify characters that are actually to be printed, spaces, or control data (such as equal start and end). It identifies whether the data is for a character but cannot be printed, and if it is a character that should be printed, the contents of the register 15 with a counting function are incremented by 1, and when all the data has been identified, it is within the equal allocation range. The number of characters (indicated by CH) contained in is obtained in the register 15.

In addition, when the data is a space or the like, by adding 1 to the contents of the register 16 having a counter function,
When the identification of all data is completed, the number of spaces (indicated by SP) included in the equal allocation range is obtained.

Next, the character spacing calculation means 11 calculates the character spacing by subtracting the number of characters held in the register 15 by one, and stores the resulting character spacing (indicated by MK) in the register 17. Each numerical value obtained in this way is B in the example of Figure 2.
As shown in , 5P=6. CH=5, MK=4.

Next, in the equal allocation space calculation means 12, the number of spaces to be allocated equally (SP) is divided by the number of character spaces (MK) to calculate the number of spaces arranged at each character interval, and the quotient value is calculated. The number of evenly divided spaces (
MS) and the number of remaining spaces (SPD)
is stored in register 19. In the example in Figure 2, MS=I
5PD=2.

Furthermore, in the remaining space dot conversion means 13,
The number of remaining spaces stored in register 19 above (SPD
) is calculated based on the actual printing dots on the printer. In this case, when printing in character units (including spaces), normal printers calculate the number of dots that make up a character (for example, 24 dots in the X-axis direction). After printing the next character (minutes), the next character is printed after moving by a predetermined number of spacing dots (for example, 3 dots), so the character pitch is set by adding a predetermined number of dots to the character width. Use the added value.

In this way, the number of dots in the remaining space (dat), which is the result obtained by the remaining space dot conversion means 13, is stored in the register 20. Furthermore, by dividing the number of dots in the remaining space (dat) by the number of character spaces (MK), the quotient is stored in the register 21 as the number of evenly divided dots (represented by MDI) allocated between each character, and the remainder is is stored in the register 22 as the remainder dot number (MD2). In the example of FIG. 2, when the character pitch is 27 (24 dots for characters, 3 dots for 10 spacing) as shown in D, doL=54 MDI=13. MD
2=2 is obtained.

In this way, once each numerical value for equal allocation is obtained,
Printer 3 is used to print the text data in an evenly distributed manner.
When transferring the data to the buffer 4, the print data generating means 23 of the processing section 1 generates data to be sent to the printer.

In that case, after the first character data (character code) to be printed, the number of space data (character code) specified by the MS of the register 18 is placed, and then the code for displaying the image data and the number of spaces specified by the register 21 are placed. Arrange image data representing the space of the number of dots.

The second character data follows, and space data and image data are arranged in the same way as the first character. For the image data following the second and subsequent character data, if the value stored in the remainder dot number MD2 stored in the register 22 is 1 or more, the number of dots formed by the image data is added to a value of 1, The number of remaining dots is set to a value of -1 and distributed evenly between the number of dots between each character.

The data for equal allocation sent from the processing section 1 is stored in the buffer 4 of the printer 3, and character data and space data are printed using a dot pattern using a well-known character pattern generator (not shown). Evenly distributed printing is performed by moving the image data by a specified number of dots (printing a predetermined number of blank spaces).

In the example in Fig. 2, one piece of space data follows the character 'B' as shown in E, followed by 13 dots of image data (space), and each character '
After .degree. 2.degree. to .degree. 4.degree., the number of dots 13, 14, and 14 according to the image data are placed after a space, respectively, and the remaining number of dots MD2 is distributed.

[Example] A configuration diagram of an embodiment of the present invention is shown in FIG.

In FIG. 3, a central processing unit (represented by CPU) 30 processes various functions instructed by a keyboard 32 according to the processing flow of a program storage device 33, and
M31 stores text data to be equally allocated, which is manually input from the keyboard 32 or from the auxiliary storage device 34 such as a magnetic disk device. In addition, each numerical value CH, SPM shown in Fig. 1 used for the equal allocation process is stored in the RAM.
A register for storing K, etc. is provided.

The printer 36 is equipped with a printer control unit 35, which receives data for uniform allocation printing from a buffer memory 351, processes character data in a character data processing unit 352, and performs printing control on a character-by-character basis; Dot-by-dot printing control is performed in the data processing unit 353. A processing flow diagram of equal allocation in the configuration of one embodiment is shown in FIG. (a) and FIG. 5(b), step 47
FIG. 6 shows a flowchart showing the details of process (2).

To explain Figure 4, first, one code is extracted from the line data of the text that is subject to equal allocation.
1) Determine whether it is the end of the line data, and if it is not the end, perform a code identification check (43). If the code is an equal allocation start code, proceed to the process of step 46 (details will be described later). Then, count the number of characters and spaces until the end of even allocation, calculate the character spacing, and further calculate the number of evenly allocated spaces, the number of remaining spaces, the number of dots in the remaining spaces, the number of evenly allocated dots, and the number of remaining dots.

Next, the process moves to step 47 (details will be described later), and for each character data within the range of equal allocation (from the code position of the start of equal allocation to the code position of the end of equal allocation),
An inter-character space made up of the number of evenly divided spaces obtained in step 46 above and the image data of the number of evenly divided dots (if there is a remaining number of dots, one allocated dot is added) is added and transferred to the printer's buffer. do. After this step 47, the process returns to the first step 41 and extracts the next code in the line data, but since the line data for which equal allocation has been specified has ended, the process advances to the end of the line data in step 42. , for line data for which equal allocation is not specified, the data is transferred to the buffer in steps 43 to 45 (step 44 replaces the code with a space in the case of a code indicating the end of equal allocation).

To explain the contents of the process (2) shown in FIG. 5(a), since the equal allocation start code is identified in step 43 of FIG. 4 above, the contents of the SP register holding the number of spaces are determined in step 50 Add 2 to . Note that the number of spaces is counted in half-width spaces, so in the case of full-width spaces, 2 is added.

Next, the next code is extracted from the row data, and if the code indicates that the equal allocation has been completed, 2 is added to the contents of the register SP that counts the number of spaces (53 in Figure 5 (a)), and the process proceeds to ■. If not, check whether the code is a space (54), and if it is a space, determine whether horizontal expansion is specified for that character, and if horizontal expansion is specified, add 4 to the contents of register SP. (If horizontal expansion is selected, the entire range will be expanded), otherwise register S
2 is added to P. Returning to step 5, if the code is a control code (excluding equal start and end codes), it is checked whether it is enlarged and full-width/half-width. If it is not a control code, determine whether the data is full-width data (characters) (60). If it is full-width data, add 1 to the register CH for the number of characters (61). If it is not full-width data, then check the code. The upper or lower byte of is a space (
If neither is a space, it is assumed that there are two half-width characters, and 2 is added to the contents of the register CH that holds the number of characters.63) If one is a space, horizontal expansion is specified. If it is specified, add 2 to the contents of register SP (65), and if it is not specified, add 1 to the contents of register SP.
66), and 1 is added to register CH as one half-width character.

Steps 51 to 67 are repeated and when the equal allocation end code is detected in step 52, 2 is added to the register SP and the process moves to step 68 in FIG. 5(b). In this step 68, 1 is subtracted from the number of characters stored in register CI] to obtain the number of character intervals, which is then stored in register MK. Next, the content of register MK is determined, and if it is 0, the content of register MK is set to 2 in step 69.

This means that an MK of 0 indicates that there is one character, and in that case, in order to position that one character in the center of the even allocation range, the number of characters between characters is set to 2 (start It is assumed that there are two numbers between the space at the position to the center character and from the character to the space at the end position. Similarly, if the value is -1 in step 69, it means that the character to be printed is 0, and in that case, the process ends.

If the contents of register MK are other numerical values, in step 71, the contents of register SP are divided by the contents of register MK, and the quotient value is stored in register MS. Next, the remainder obtained as a result of the division in step 71 (indicated by SP%MK) is multiplied by (the number of dots in a pitch of several tens of characters per character), and the result is stored in a register da.
Store in t.

Next, the contents of the register dat obtained above are transferred to the register M
Divide by the contents of K, store the resulting quotient in register MDI, and store the remainder in register MD2. Process above ■
end.

Next, following the above process (2), process (2) shown in FIG. 6 will be explained.

First, in step 80, a read address (
Add 1 to the address register (not shown) Next, determine whether the register CH (number of characters) is 0 or not (Figure 6 (81))
, 0, the number of characters is 0, so a space is transferred and this process ends (82)).

If it is not 0, the code is retrieved from the address set above and it is determined whether the code indicates that equal allocation has been completed (84); if not, it is checked whether the contents of the register CH are 1 (85). ■If not, identify whether the code is a control character, and if it is a control character, transfer the code to the buffer (print data buffer of RAM 31 in Figure 3), otherwise determine whether the code is a space or not. do. When it is a space, move on to extracting the next code,
Otherwise, transfer one character to the buffer (in RAM).

Next, it is determined whether the register MS (number of evenly divided spaces) is larger than O, and if it is, the number of character spaces specified by MS is transferred to the buffer. Then register M
Compare K (the number of character intervals) with the register MD2 (the number of remaining dots), and if the result is negative, 1 is added to the contents of the register MDI, and if they do not match, the process immediately moves to step 95.

In step 95, register MDI (number of evenly divided dots)
Generates an image space according to the contents of and transfers it to the buffer. Thereafter, the contents of register MK are incremented by 1.

The processing of steps 93, 94, and 96 above is performed by register MD.
This is done to control from which character interval (indicated by register MK) the number of dots left over from 2 is allocated.

Thereafter, the process moves to step 83 via the path (2), where the space character and image space for each character are transferred to the buffer, and print data is created. When the equal allocation end code is detected in step 84, this process ends.

Note that in step 85, when the code is taken out, C
If H=1, the processing when there is one character is performed, the CH is set to 0, the character space is transferred, and steps 93~
The process at 96 transfers the image space to the buffer, then the character code, and then the space and image space.

To summarize the operation of the above process ■, if the number of characters is 1, the space between characters is 1 character, the space between 1 character, 1 character, or more. be.

FIG. 7 shows an explanatory diagram of a specific example of operation according to the present invention.

When performing equal allocation processing on the row data shown in A in the figure, each numerical value shown in ■ to ■ in B is
Obtained by the process shown in Figure (b).

By performing the processing shown in FIG. 6 based on the numerical value obtained from B, data for the printer C1 is obtained in the buffer. C8 has the character "1"
Image data representing a character space and six dots are shown.

In other words, "H" represents data in hexadecimal display, the first A represents the start of a full-width character, the mouth code represents the number 1, the next C represents the end of the full-width character, and 2 represents the half-width space. Represents 2 pieces. The ``■'' following this 29 is a function designation and represents the start of the image data, the ``h'' represents the length of 6 dots (the number of printed dots in the horizontal direction), and the ``g'' represents the width (vertical direction) of the image data. The next line indicates the width of one line, and the subsequent line indicates a 16-dot data string, and this line indicates 6 of the 16 dots (indicated by the line). The print hand can be moved.
