Description

[Detailed description of the invention]

(a) Industrial Application Field The present invention relates to a printing control device. (b) Prior art Current English word processors are based on proportional printing with equal character spacing, and perform various controls such as line end processing, right alignment processing, right 1/2 alignment processing, centering processing, right alignment processing, etc. Print out. Figure 1 shows the basic configuration of current English word processors, where 1 is an input means such as a keyboard, and 2 is an input means such as a keyboard.
CRT display, 3 is a printer, 4 is a storage unit,
5 is a control section. In such a device, the data inputted from the input means 1 is displayed and output on the CRT 2 screen,
While looking at the display screen, make corrections, etc., and store it in the storage section 4.
Store inside. Further, the data stored in the storage section 4 is printed out by the printer 3. This operation is controlled by the control section 5 based on the signal input from the input means 1, and the above-mentioned line end processing and the like are also controlled by the control section 5. Next, each process such as line end process will be explained. (i) End-of-line processing Assume that a character string such as "ABC〓〓〓XYZ" as shown in FIG. 2A is displayed on the first line of the CRT screen 6. In the figure, "" and "" are left and right margins that define the format of one line. When the character string is printed out by the printer 3, if proportional printing is performed at predetermined character intervals, the character string may not fit within the printing area 8 on the printing paper 7, as shown in FIG. 2B. In such a case, end-of-line processing involves changing the character spacing so that the character string fits within the print area 8. (ii) Right alignment process This process is performed when proportionally printing the character string displayed in FIG. This aligns the end of each line with the right margin position when a margin SP occurs between the right margin position (referred to as the right margin position) and the last character of the character string. Specifically, this is done by appropriately distributing the above-mentioned margin SP to each space "〓" in the line. (iii) Right 1/2 alignment process This process is substantially the same as the right alignment process described above, and is a process of aligning the last character of the line to 1/2 SP from the right margin position. (iv) Centering process Such a process is performed, for example, as shown in Figure 4A.
This is a process for printing the character string "ABC" displayed on the screen 6 so that it is located at the center of the printing area 8 as shown in FIG. 4B. In FIG. 4A, "□C" is a centering mark, and the character string sandwiched between these marks is subjected to the above-mentioned centering process. (v) Right-justification processing Such processing is performed, for example, when printing the character string "ABC" displayed on the CRT screen 6 as shown in FIG. This is the process of doing so. In FIG. 5A, "□R" is a right-justification mark, and character strings located after such a mark are subject to the right-justification process. Current English word processors use type printers. Therefore, the control device that executes each of the above-mentioned processes has been constructed on the premise that the output is to be output to a type printing device. However, dot type printing devices are now being widely used as printing devices because they are capable of printing complex characters such as Chinese characters and graphic data. (c) Purpose of the Invention The present invention has been made in view of the above points, and it is an object of the present invention to provide a printing control device that can achieve each of the above functions even when using a dot type printing device. The purpose of this invention is to perform proportional printing for each character, and to solve the problem of print misalignment occurring when each line is treated as a unit of processing in the case of continuous vertical lines spanning a plurality of lines. (D) Structure of the Invention The present invention provides a text memory that stores a document including vertical lines, a line buffer that reads and retains information in the text memory, and a system that stores the vertical lines in a line read into the line buffer. position management storage means for searching character positions from the beginning and storing the positions;
A pattern and width storage means that stores the dot width in the horizontal or vertical direction of a dot matrix whose dot matrix size varies depending on the type of character/symbol, etc., an image buffer that stores the dot pattern for one line to be printed, Start dot position creation means for creating a start position for writing into the image buffer; start dot position storage means for storing the start position for writing each dot pattern into the image buffer created by the start dot position creation means; a basic dot position storage unit storing basic start dot positions; a vertical check line determining means for determining whether the document read from the line buffer is a vertical check line; and the start dot position storage unit. pattern image creation means for creating a dot pattern read from the pattern and width storage means in the image buffer based on the start position stored in the pattern image buffer; and a current dot for storing the start dot position of the immediately preceding pattern and the width of the pattern. position storage means, a start position selection section for selectively outputting the output of the basic dot position storage section or the current dot position storage means; The selection section selects the output of the basic dot position storage section based on the position of the vertical check line of the position management means, activates the start dot position creation means based on the basic dot position, and performs the vertical check line judgment. When the means determines that the dot is a character or symbol, the start position selection section selects the output of the current dot position storage means and activates the start dot position creation means. (E) Embodiment First, before explaining the embodiment, a proportional printing method when using a dot printing device and the above-mentioned processes (i) to (v) based on this method will be briefly explained. (a) Proportional printing method Currently, printing control devices for outputting using dot-type printing devices have a font pattern in which each character is represented by, for example, 24 x 24 dots or 32 x 32 dots. Each character is printed out by outputting it to a printing device. However, if each character is made to have a common matrix size in this way, the actual spacing l1, l2 between characters will be different as shown in FIG. 6, so that proportional printing will not be possible. This is the character width W1, W
This is because characters with different W3 values are made into dot matrices of the same size. Note that m and n in FIG. 6 are dot matrix sizes. In view of this point, the present inventor decided to define the matrix size in the width direction as a font pattern for proportional printing according to the substantial character width. Specifically, as shown in FIG.
The font pattern includes blank dot areas labeled 1 and L2. Therefore, the dot matrix size of the font pattern of the letter "I" is m×(L1+W1+L2). Similarly, the letter "A" has a font pattern of m×(L1+W2+L2), and the letter "M" has a dot matrix size of m×(L1+W3+L2). Furthermore, the above L1,
L2 is fixed. Next, a schematic process for converting the font pattern configured in this way into an actual printing form will be explained using FIG. 8. Specifically, a case will be described in which the character string "ABC" displayed on the CRT screen 6 is to be printed as shown in FIG. 9, for example. The widths of the font patterns of the characters "A", "B", and "C" are "18", "19", and "17", respectively. In FIG. 8, numeral 10 is an image buffer, in which a print image for one line is stored as a dot pattern. In other words, the character string "ABC" is located at the beginning of the line, and the widths are "18", "19", and "17", so the font pattern of the character "A" is the 0th one of the image buffer 10. The font pattern for the letter “B” is from the 18th dot row to the 36th dot row, and the font pattern for the letter “C” is from the 37th dot row to the 54th dot row.
They will be written in respective dot rows. To write a font pattern to the image buffer 10, first, the font table 11 stores the font pattern of each character and its width.
The width of each of the characters "A", "B", and "C" is read out sequentially, the writing start position of each character to the image buffer 10 is determined based on the width value, and the position is set in the start dot table. This can be done by first writing in the corresponding area of dot table 12, and then storing the font pattern read from font table 11 based on the contents of dot table 12 in image buffer 10. As described above, proportional printing can be done by simply setting the font pattern width of each character appropriately, but for characters that are continuous over multiple lines, such as vertical lines, for example, the writing start position (hereinafter referred to as When determining the start dot position (referred to as the start dot position), a deviation may occur during printing. Therefore, as a method to prevent this, the start dot position of a vertical dot or the like may be defined by the character position (hereinafter referred to as column position) from the beginning of the line in which the dot is located. In addition to vertical lines, there are format marks that divide one line into processing units as continuous marks that span multiple lines. (b) Right alignment processing As shown in Figure 10A, in proportional printing, if the last character of a line is located within the print area by m dots from the right margin, the above m dots are aligned with the characters of that line. Allocate to the space that exists between. This distribution method is to calculate the quotient A and the remainder B from m/n, where the number of spaces above is n, distribute the quotient A to each of the above spaces, and distribute 1 each to B spaces in order from the first space of the line. Sort out the dots one by one. Specifically, for example, as shown in FIG. 10B, n=
2. If there is a line such as m=3, the quotient of m/n A=
1, the remainder B=1, so the leading space is 21
Two dots will be distributed to the space 22, and one dot will be distributed to the second space 22. Therefore, if the width of the space is, for example, "18" during proportional printing, the widths of the first and second spaces 21 and 22 become "20" and "19", respectively, by such right alignment processing. At this time, as the width of each space changes, the start dot position of each character also changes, but this can be done by changing the contents of the start dot table 12 in accordance with the amount of change in the space width. (c) Right 1/2 alignment process This process is basically the same as the right alignment process described above, so a description thereof will be omitted. (d) Right-justification processing This processing is performed by simply proportional printing as shown in Fig. 11, for example, when there is a difference of m dots between the rightmost character of the character string "ABC" for which right-justification is requested and the right margin position. This can be done by shifting the start dot position of each character to the right by m dots. To change the start dot position, simply add +m to the start dot position information of each character in the start dot table 12. (e) Centering process Such a process is performed when a line containing the character string "ABC" to be centered is simply printed according to the predetermined font pattern width of each character, as shown in FIG. 12, for example. According to the start dot position A of the first character "A" of the above character string, the start dot position X of this line, the final dot position B of the last character "C" of the above character string, and the right margin position Y, (X+Y-A -B)/2 is calculated, and the start dot position of each character of the character string "ABC" is changed by the calculated result. When a fraction below the decimal point occurs in this calculation, rounding is performed. Note that such a position change only changes the contents of the start dot table 12. (f) End-of-line processing Such processing is performed, for example, as shown in Figure 13, when each character is printed in accordance with a predetermined font pattern width and the character is printed beyond the right margin position. The width of the font pattern is decreased one dot at a time. Specifically, each start dot position information in the start dot table 12 is changed according to its column position n, that is, (n-
1) each of the above information is decreased by 1). Although each of the above processes has been explained on a line-by-line basis, it is also possible to perform the above-mentioned processes on a block-by-block basis using format marks such as vertical lines and indent marks, as shown in FIG. 14, for example. In the following embodiments, an apparatus that processes blocks will be described. FIG. 15 shows the overall configuration of the device of this embodiment,

This is to determine whether or not the value exceeds a certain value. That is, this is to prevent the above-mentioned m from being too large, the number of dots distributed to each character space becomes large, and the character space becomes wide, which becomes aesthetically undesirable. FIG. 21 is a flowchart showing the processing program of the control section 100, and its operation will be specifically explained based on this flowchart. First, in step S1, first initial settings are performed. Specifically, the counter value in the read column position management section 301 is set to "0" based on the reset signal R1.
At the same time, the format mark column position storage section 101, start dot position storage section 102, space column storage section 318, etc. are cleared by a reset signal from the control section 100 (not shown). In step S2, one line of code to be processed below is transferred from the text memory 202 to the line buffer 20.
3. Specifically, such an operation is executed by applying a control signal C1 to the text management means 201. Further, in step S3, the means 201 searches the format mark column position management unit 204 for the format mark position in the row buffer 203, and sets the position information in the format mark column position storage unit 101. In step S4, second initial settings are performed. Specifically, centering information storage section 304, processing information storage section 308, end character column position storage section 3

Add 1 to the contents of the column counter in 1. Specifically, the count-up signal from the control unit 100
Executed based on UP1. The contents of such a column counter are output as a column position signal CP,
Based on the signal CP, in step S6, the reading section 202 outputs one code in the row buffer 203 located at the column position corresponding to the signal CP as a read code CC. In step S7, the centering mark determining section 303 determines whether or not the code CC is a centering mark. If it is a centering mark, the process proceeds to step S8; otherwise, the process proceeds to step S12. In step S8, the centering information storage section 3
The first storage area 305 in 04 is searched and its contents are determined in step S9. That is, if the centering mark "presence" information is set in the first storage area 305, the process advances to step S10, where the centering processing means 400 executes centering processing. If the centering information has not been set, the process advances to step S11 and the centering information is set. Specifically, centering "presence" information is set in the first storage area 305, and a column position signal CP is set in the second storage area 306. When the processing of steps S10 and S11 is completed, the processing proceeds to step S12. In addition, the above S8~
The processing in step S12 is performed by the centering determination unit 30.
3. In step S12, it is determined whether or not the code CC is a right-justified mark. If it is a right-justified mark, the process proceeds to step S13, and if not, the process proceeds to step S14. In step S13, right-justification information is set in the processing information storage section 308. Specifically, a column position signal CP is set in the right-justification start position area 309 in the storage unit 308, and information indicating that right-justification processing is "present" is set in the right-justification processing area 310. Furthermore, S1
The processing of steps 2 and 13 is executed by the right-justification determination unit 307. In step S14, it is determined whether or not the code CC is a character code. If it is a character code, the process executes steps S15 and 16 and proceeds to step S17; otherwise, the process proceeds directly to step S17. In this step, the character code is a code representing alphanumeric characters, numbers, etc., excluding format marks, centering marks, right-justification marks, spaces, etc. In step S15, start character column position information is set in the start character column position storage section 314. Specifically, when the content of the start character information area 315 of the storage section 314 is "0", "1" is set in the area 315, the column position signal CP is set in the start character position area 316,
Further, when the content of the area 316 is "1", no processing is performed on the storage section 314 and the process advances to step S16. In step S16, the end character column position is stored in the end character column position storage section 313.
Set to . Specifically, the column position signal CP is set in the storage section 313. Note that S14 to S1
The six-step process is executed in the character determination section 312. In step S17, the start dot position creation means 500 creates the start dot table 12 described above based on the code CC and column position signal CP. In step S18, it is determined whether or not the code CC is a space code. If it is determined that it is a space code, in step S19, the column position signal CP in the start column storage section 318 is
Set "1" in the area corresponding to . Furthermore, S1
The processing of steps 8 and 19 is performed by the space determination unit 317.
is executed. In step S20, the format mark determination unit 319 determines whether the code CC is a format mark, and if it is a format mark, whether it is a line regulation mark or a block regulation mark, and outputs the result as a signal.
It is output to the control unit 100 as MD. Specifically, the signal MD is output as a 2-bit digital signal, and each of these 2-bit signals has a meaning as shown in the table below.

[Table] In steps S21 and 22, it is determined whether the code CC is a format mark and not a left margin based on the signal MD from the format mark determination unit 319, and
If it is not a format mark or the left margin, the process returns to step S5, and if it is a format mark and is not the left margin, the process returns to step S23.
Proceed to step. In step S23, the start character information area 315 of the start character column position storage section 314 is searched to determine whether or not there is a character in the block currently being processed. That is, if "1" is set in the area 315, it is assumed that there is a character in the block, and the process proceeds to step S24, and if "0" is set, it is assumed that there is no character. The process advances to step S32. In step S24, the line end processing described above is performed. Specifically, the control signal C6 from the control unit 100
The end-of-line processing means 900 executes this based on the following. When this process is completed, the process advances to step S25. In steps S25 to S31, it is determined which of the right-justifying process, the right-justifying process, and the right 1/2-aligning process is to be performed, and each process is executed. Specifically, in step S25, the processing information storage unit 308 is read out, and if it is determined that the right-justifying process "exist" information is stored in the right-justifying processing area 310, the right-justifying process is performed based on the control signal C3 in step S29. Means 600 performs right-justification processing. In step S26, the zone check means 1100 performs the zone check described above based on the control signal C8, and based on the check result XC, it is determined whether right alignment and right 1/2 alignment are possible. If it is determined that this is not possible, the process proceeds to S32.
Proceed to step, and if it is determined that it is possible again, proceed to step S2.
In steps 7 and 28, the processing information storage unit 308
Based on this search result, it is determined whether to perform the right alignment process in step S30, the right 1/2 alignment process in step S31, or do nothing.
The process proceeds to either step 1 or 32. still,
When steps S29 to S31 are completed, the process proceeds to S32.
Proceed to step. Further, each process of steps S30 and S31 is executed in the right alignment processing means 700 or the right 1/2 alignment processing means 800, respectively, based on the control signal C4 or C5. In step S32, it is determined whether or not the end of the currently processed block is a block regulation mark. If it is a block regulation mark, the process returns to step S4, and if it is not a block regulation mark, that is, if it is at the right margin, the process returns to S33. Proceed to step. The above judgment is made by the format mark judgment unit 3.
This is done based on the determination result signal MD output from 19. In step S33, the pattern image for one line described above is created. Specifically, this is done by the pattern image creation means 1000 based on the control signal C7. When this process is completed, the process returns to step S1. The processing operation according to the flowchart of FIG. 21 is performed in a loop consisting of steps S5 to S22, in which the start dot table 12 is created while performing centering processing if necessary for each block, and the end of the block is detected (steps S21 and S22). ) Then execute steps S23 to S31 to right-justify, right-align, right 1/2 in block units.
Processing such as alignment is performed to correct the start dot position of each character. Therefore, when a plurality of blocks exist in one line, a loop consisting of steps S4 to S32 is executed, and each process is performed on a block-by-block basis. Furthermore, when the processing of each block in one line is completed, a pattern image is created in step S33, and then the process returns to step S1 again to process the next line. Next, the configuration and operation of each means such as the centering processing means 400 and the start dot position creation means 500 will be explained. FIG. 22 shows the configuration of the centering processing means 400, and 401 is a centering processing control section composed of, for example, a microcomputer, which controls the following sections using control signals C10 to C14. In the following explanation, the numerical values in [ ] indicate the numerical values in the case of the schematic diagram of FIG. 23. "Block position search unit 402"... Searches for the column position of the format mark closest to the currently read column position CP. Specifically, by inputting the control signal C10, the format mark column position storage unit 101 is searched based on the column position signal CP, and the column positions CPA[10] and CPB[18] are searched and output. "Block dot search unit 403"... Searches the basic dot position storage unit 103 based on the column positions CPA and CPB sent from the block position search unit 402, and searches the column position CPA+1[11],
The start dot positions [198] and [324] corresponding to CPB [18] are read out and stored in the start area 405 and end area 406 of the block dot position storage section 404. That is, as shown in FIG. 23, if the current column position signal CP indicates the column where the right centering mark "□C" is located, the start area 405 and the end area 40

"Processing dot position search unit 407": Searches for the start dot position of the first character of a character string to be subjected to centering processing. Specifically, the centering information storage unit 30

That is, in FIG. 23, the start dot position information [234] of the character "a" is read out and stored in the character start dot storage section 408. "First calculation unit 409"...Calculates the difference between the start dot position of each character after centering processing and the start dot position obtained from a predetermined font pattern width. That is, the number of corrected dots at the start dot position is calculated. Specifically, the following calculation is performed based on the control signal C12, and the calculation result _d1 is output. d ₁ = {Y-X-(B-A)} x 1/2 + X-A = 1/2 (X-Y-A-B) = [8] Note that X...Start area of block dot position storage section 402 405 [198] Y... Value stored in the end area 406 of the block dot position storage section 404 [324] A... Value stored in the character start dot storage section 408 [234] B...
