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 "ABCXYZ" shown in FIG. 2A is displayed on the first line of the CRT screen 6. In addition, "", "" in the figure
are the 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 allocating the above-mentioned margin SP to each space "" in the line. (iii) Right 1/2 alignment process This process is almost the same as the right alignment process above,
The last character of the line is 1/2SP from the right margin position
This is the process of aligning. (iv) Centering process Such a process is, for example, as shown in Figure 4A.
This is a process for printing the character string "ABC" displayed on the CRT screen 6 so that it is located at the center of the print 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 This processing is performed, for example, on a CRT as shown in Figure 5A.
Character string “ABC” displayed on screen 6
When printing, print area 8 as shown in Figure 5B.
This is the process to position it at the right end of . 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 a dot type printing device is used. (d) Structure of the Invention The structural features of the present invention include a first storage means capable of storing at least one line of dot patterns having different dot matrix sizes depending on the types of characters/symbols, etc. in the form of a print pattern; a second storage means storing the storage start dot position of each dot pattern in the storage means; a plurality of processing means for performing various processes of proportional printing; a selection means for selecting one of the processing means; determining means for determining the output, the determining means determines the selected process for the proportional printing, and the storing start dot position of each dot pattern in the second storage means is determined based on the determining means. It consists in changing the state before processing. (E) Embodiment First, before describing an embodiment, a proportional printing method when using a dot type 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 and l2 between characters will be different as shown in FIG. 6, so that proportional printing will not occur. This is because the characters with different character widths W1, W2, and W3 are made into dot matrices of the same size. The 6th
In the figure, m and n 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 in accordance with the substantial character width. Specifically, as shown in FIG. 7, the character "1" having a character width W1 has a font pattern with blank dot areas L1 and L2 added to the left and right sides, respectively. Therefore, the dot matrix size of the font pattern of the letter "I" is m.times.(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). Note that the above L1 and L2 are 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. In addition, each letter “A” above,
The widths of the font patterns of "B" and "C" are "18", "19", and "17", respectively. In Figure 8, 10 is an image buffer;
A print image for one line is stored in the buffer 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 of the letter "B" is written in the 18th to 36th dot rows, and the font pattern of the letter "C" is written in the 37th to 54th dot rows, respectively. It happens. To write the font pattern to the image buffer 10, first, the widths of the characters "A", "B", and "C" are sequentially read out from the font table 11 in which the font patterns and widths of the characters are stored. , find the writing start position of each character in the image buffer 10 based on the width value, write this position once in the corresponding area of the start dot table 12, and then write the font based on the contents of the dot table 12. This can be done by storing the font pattern read from the table 11 in the 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 2
1 has 2 dots and 2nd space 22 has 1
The dots will be sorted out. Therefore, if the width of the space is, for example, "18" during proportional printing, the width of the first and second spaces 21 and 22 will be "20" and "20", respectively, by such right alignment processing.
It becomes “19”. 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 This 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, each of the above pieces of information is decreased by (n-1). Although each of the above-mentioned processes has been explained on a line-by-line basis, the above-mentioned processes can also be carried out on a block-by-block basis using formatting marks such as vertical lines and indentation 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,

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, the first storage area 30

If not, proceed directly to step S17.
In this step, the character code is a code representing an alphabet, a number, 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 unit 314 is "0", "1" is set in the area 315, and the column position signal is
Set CP 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 set in the end character column position storage section 313. Specifically, the column position signal CP is set in the storage section 313. Note that the processing of steps S14 to S16 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, "1" is written in the area corresponding to the column position signal CP in the start column storage section 318. Set. Note that the processing in steps S18 and S19 is executed by the space determination section 317. 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, determines whether it is a line definition mark or a block definition mark, and sends the result to the signal MD.

[Table] In steps S21 and 22, the above format mark judgment section 3
It is determined whether the code CC is a format mark and not the left margin by the signal MD from 19, and if it is not a format mark or the left margin, it returns to step S5, and if it is a format mark and is not the left margin, it is processed. Proceeds to step S23. 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. In other words, “1” is placed in the above area 315.
If the block is set, it is assumed that there are characters in the block, and the process proceeds to step S24.
If "0" is set, it is assumed that there is no character and the process proceeds to step S32. In step S24, the line end processing described above is performed.
Specifically, it is executed in the end-of-line processing means 900 based on the control signal C6 from the control section 100.
When this process is completed, the process advances to step S25. In steps S25 to S31, it is determined whether to perform right alignment processing, right alignment processing, or right 1/2 alignment processing, and each process is executed. Specifically, in step S25, the processing information storage unit 308 is read, and if it is determined that the information indicating that right-justification processing is “present” is stored in the right-justification processing area 310, the right-justification processing 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 step S32, and if it is determined that it is possible, the alignment processing area 311 of the processing information storage unit 308 is searched in steps S27 and 28, and based on this search result, the process proceeds to step S30. It is determined whether to perform right alignment processing in step S31, right 1/2 alignment processing in step S31, or do nothing, and proceed to steps S30, 31, or 32, respectively. Note that when steps S29 to S31 are completed, the process advances to step S32. 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. If it is not a block regulation mark, that is, if it is at the right margin, the process returns to step S33. Proceed to step. The above judgment is performed by the format mark judgment unit 319.
This is done based on the determination result signal MD output from the. 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 22). Then, steps S23 to S31 are executed to perform right alignment, right alignment, right 1/2 alignment, etc. in block units, and 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, S33
A pattern image is created in step S1, and then the process returns to step S1 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 above process, in steps S101 to S104, a correction value _d1 of the start dot position to be corrected by the centering process is obtained, and in steps S105 and 106, the start dot position is corrected based on the correction value _d1 . It is determined whether the beginning of the character string to which the centering process is applied does not exceed the format mark defining the start of a block containing such a character string, and if it does not, execute step S107 and proceed to step S108. This step S108 will be described later, but it is intended to prevent other processing from being performed on the character string that has been subjected to such centering processing when a request for right alignment processing etc. is made in such a block. It is. FIG. 25 shows the line end correction means 900, 901

is input, the contents of the character final dot position storage section 507 to be output later are read out, the SD is subtracted, and the result of the subtraction is set in the storage section again. The character final dot position storage section stores the final dot position [312] of the last character in the block. FIG. 27 is a flowchart showing the operation of the dot deletion means 950 of FIG. 26. First, in step S201, the processing start position search unit 952 sets the processing start position [17] in the start area 954 of the processing range storage unit 953 based on the control signal C31, and also sets the column position signal CP[23] in the end area 955. is set. In step S202, the contents of the start area 954 are transferred to the column counter 9 based on the control signal C32.
Then, in step S203, the contents of the counter 956 are incremented by 1 to [18] by the count-up signal UP2, and processing starts from the 18th column. At step S204, the subtracted counter 957 is cleared by the reset signal R2, and at step S205,
At step 206, the contents of the subtracted counter 957 and column counter 956 are incremented by 1 to become [1] and [19], respectively. A first determination is made in step S207.
Specifically, the process described above is executed in the first determination unit 958 based on the control signal C33, and as a result Z2
is compared in the control unit 951 in step S208 to see if it is "0". In such a comparison, if “Z2=0”, the processing is
The process advances to step S209, and if "Z2=1", the process ends. In this case, CD = [19], EC = [23] and CD
Since ≠EC and Z2=0, processing continues. In step S209, the above-described subtraction process is executed in the dot subtraction section 959 based on the control signal C34. In this case, a new start dot position is calculated as shown in FIG. 29b. A second determination is made in step S210.

When this process is completed, the process returns to step S205. That is, in steps S201 to S204, the column position range in which dots should be deleted is determined, and the column counter 956 and subtractable counter 957 are initialized. Next, in a loop consisting of steps S205 to S212, the start dot position within the above range is sequentially changed, and when this change process is completed,
Exit the loop at step S208. FIG. 28 is a flowchart showing the operation of the end-of-line correction means 900 of FIG. 25, and will be explained using FIG. 29a as an example. First, in step S301, by outputting the control signal C21, the block end column position search unit 902 searches for a column position that meets the conditions described above.
Search for ECP [23]. Next, in step S302, the basic dot position BSDP [315] corresponding to the column position ECP is searched. Such a search is executed by the basic dot position reading section 903 based on the control signal C22. In step S303, the subtraction section 904 performs the above-mentioned calculation CEDP-BSDP in response to the control signal C23. In step S304, the determination unit 9
Based on the determination result Z1 made in step 05, the control unit 901 selects the next step to be executed. That is, when "Z1=0", the process proceeds to step S305, and when "Z1=1", the process ends. In this case, Z1=0 and the process moves to step S305. In step S305, the dot reduction process is executed based on the flowchart of FIG. 27, as described above. FIG. 30 shows a start dot position creating means 500.

When a CC is sent, the font pattern width FB of the character (excluding formatting marks but including centering marks, etc.) corresponding to the code CC is read out from the width storage unit 105 of the font management unit 104 and output. "Basic dot width storage section 505"...The font pattern width BB of the write mark is stored in this storage section. "Dot width selection section 506"...consists of a multiplexer, for example, and when the control signal C42 is input, the dot width selection section 506 outputs the output FB from the width reading section 504 based on the signal Z3.
Or the content BB in the basic dot width storage section 505

When it is (character), the character width FB is output. "Character final dot position storage unit 507"...Stores the final dot position of the character located in the column position before the currently processed column position CP and stored in the column position closest to the column position CP. . Specifically, (start dot position of the above character + font pattern width of the above character - 1)

"Current dot position storage section 508": Stores numerical values that may be stored in the area within the start dot position storage section 103 corresponding to the column position CP currently being processed. Specifically, the value of (start dot position of the pattern located one position before the current column position CP + font pattern width of such pattern) is stored. The above patterns include format marks, centering marks,
Includes all right-justification marks, spaces, characters, symbols, etc. The values to be stored in the character final dot position storage section 507 and the current dot position storage section 508 will be explained in more detail with reference to FIG. 31.

Assuming that the column is specified, the character final dot position storage unit 507 stores the font pattern width [24] of the character “m” corresponding to the start dot position [125] of the character “m” located in the eighth column. The value obtained by adding and subtracting 1 from the addition result [148]

"Start dot position writing unit 512"...When the control signal C46 is input, the start position selection unit 50 writes the start dot position in the area in the start dot position storage unit 103 corresponding to the column position signal CP based on the column position signal CP.
Set the output value from 9. FIG. 32 shows the start dot position creation means 5.
This is a flowchart showing the operation of the unit 500, and the operation of the means 500 will be explained below based on the flowchart with reference to the schematic diagram of FIG. Assuming that the column position CP is 11 and the character "N" is entered here (not shown), a code determination is first performed in step S401. Specifically, it is executed when the code CC is given to the code determination unit 502 from the control unit 501, and the determination unit 50
2, it is determined whether the code CC is a code representing a format mark, as described above. In step S402, the next step to be processed is selected based on the determination result Z3 obtained in step S401. In other words, when “Z3=0” (character code), the process goes to step S403, and “Z3=0” (character code)
= 1" (format mark), the process proceeds to step S404. In this case, since it is a character code, the process moves to step S403. In step S403, the character "N" is sent from the control unit 501 to the width reading unit 504. By giving the code CC, the width reading unit 504 reads out the font pattern width FB [22] corresponding to the code CC. If the 11th column is "◇",
The process moves to step S404, and in step S404, the basic dot position reading section 503 reads the basic start dot position corresponding to the column position CP in the basic dot position storage section 102 based on the control signal C41.
Read BSDP[180]. When the processing of step S403 or S404 is completed, step S405 is executed. In step S405, based on the control signal C43,
In the start position selection section 509, select BSDP ([180] for ◇) or CURR ([167+18= for N).
185]) is selectively output. In step S406, by applying the control signal C46 to the start dot position writing section 512, the writing section 512 executes processing for setting the output from the start position selection section 509 as described above. In step S407, the control signal C42 is applied to the dot width selection section 506, so that the selection section 50
At step 6, the process described above is executed and the width [22] of the character "N" is output. Processing then proceeds to step S408;
A second addition is performed in the step. Specifically, by outputting the control signal C45 from the control unit 501 to the second addition unit 511, the addition process described above in the addition unit 511, that is, the start dot position [185]
and the font width [22], and the result [207] is set in the current dot position storage section 508. In step S409, the next step to be processed is selected based on the signal CCS sent from the character determining section 312. In other words, when "CCS=1" (character code), the process advances to step S410,
“CCS≠1” (format mark, centering mark,
When it is a right-aligned mark and a space), the process ends. A first addition is performed in step S410. Specifically, the control unit 501 sends the control signal C44 to the first
By outputting to the adder 510, the adder 5
10, that is, the addition process of the current dot position [185] and the font width [22] is performed, and the result [207] is set in the character final dot position storage section 507. Therefore, in steps S401 and 402, it is determined whether the code CC is a format mark code or not, and based on the result of this determination, step S403 or S404 is executed. Next, in steps S405 and 406, the column position in the start dot position storage section 103 is
CCS or BSDP is set in the area corresponding to CP. In other words, when “Z3=1”, BSDP
However, when "Z3≠1", CCS is respectively set. Thereafter, in steps S407 and 408, a value that may become the start dot position of the font at the column position to be processed next is set in the current dot position storage unit 508, and in steps S409 and 410, a value that may become the start dot position of the font at the column position to be processed next is set. If there is a character in CP, the final dot position of that character is stored. FIG. 33 shows a specific configuration of the right-justification processing means 600, and 601 is a right-justification processing control section composed of, for example, a microcomputer, which outputs control signals C51 to C53 based on a processing program to perform the following operations.

When 51 is input, the contents stored in the area of the start dot position storage section 103 corresponding to the column position signal CP are read out and output. In other words, the column position signal CP when such right-justification processing is executed is the 21st column position signal CP.
As is clear from the flowchart, the format mark position located at the right end of the processing block (column [11]) is specified, so the above output value [180]
is the starting dot position of such a formatting mark. "Subtraction unit 603"... Based on the control signal C52, the content [165] of the character final dot position storage unit 507 is calculated from the output value [180] from the block end dot search unit 602 ([9] column start dot position + M) font width), resulting in S[15]
(=[180]-[165]) is set in the subtraction result storage section 605. That is, such result S corresponds to m in FIG. "Start dot position change unit 604"...When the control signal C53 is input, the processing information storage unit 308 stores the contents stored in the right-justification start position area 309, that is, the column position RMC where the right-justification mark is located.
[7] and the contents ECC[9] of the end character column position storage unit 313 are read, and from (RMC+1) [8]
The above S[15] is added to the data in each area in the start dot position storage unit 103 corresponding to each column position up to ECC[9]. FIG. 34 is a flowchart showing the operation of the right-justifying processing means 600. First, in step S501, the start dot position [180] of the rightmost format mark is searched. Specifically, this is performed by block end dot search section 602 by outputting control signal C51. In S502, the value S corresponding to m shown in Figure 11
Find [15]. Specifically, as described above, it is determined by the subtraction unit 603 based on the control signal C52. In step S503, the start dot position is changed. Specifically, as mentioned above, the control signal C
This is executed by the start dot position changing unit 604 by outputting 52. Therefore, by sequentially executing steps S501 to S503, the right-justifying process is completed. (f) Effects According to the present invention, the determination means determines the process for any selected proportional printing, and the storage start dot position of each dot pattern in the second storage means is determined based on the processing means. Since the state is changed from the state before non-processing, the writing position of the dot pattern in the first storage means can be easily changed in accordance with the selected processing. Further, the present invention is not limited to the embodiments, and modifications can be made without departing from the technical idea of the present invention.
