Abstract

PURPOSE:To enable a well-balanced printed document with character size taken into acount to be easily formed, by converting a line feed pitch into a value according to a character size and thereby controlling an actual paper feed quantity. CONSTITUTION:The document-forming device is provided with, for example, nine kinds of line pitch information B, O, H, K, E, 1-4. Where line feed B is designated, reverse line feeding by 1/2 of the character size is performed. Where line feed O is designated, 0 line feeding is performed irrespective of the character size. Where line feed H is designated, forward paper feeding by 1/2 of the character size is performed. Accordingly, line feeding is conducted by feeding a printing paper by an amount equal to the absolute value of the difference between a line feed paper feed quantity and a line printing paper feed quantity in the direction according to the sign of the difference, on each printing in the relevant line.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a document creation device that controls the line feed amount of a printed document according to character size.

[Technical background of the invention and its problems] Recent document creation devices such as Japanese word processors have
In the middle of this period, there are many cases in which the font size and line break pitch can be changed.

Conventionally, in this type of document creation device, the font size and line break pitch are managed independently, making it difficult to specify a line break pitch that is in balance with the font size, making it difficult to create a well-balanced printed document. That was difficult.

Furthermore, conventional document creation devices have not been designed to fully utilize the variable character size function to create a variety of printed documents.

[Purpose of the Invention] This invention was made in view of the above circumstances, and its purpose is to control the actual line feed amount by converting a specified line feed pitch value to a value corresponding to the character size. To provide a document creation device that can realize a line feed pitch commensurate with the above without placing a burden on an operator, and can easily create a well-balanced printed document in consideration of character size.

Another object of the present invention is to provide a selectively specified line feed pitch value with a plus/minus sign that defines the line feed direction, and to control the line feed amount in accordance with the character size by controlling the line feed direction. It is an object of the present invention to provide a document creation device capable of fully exhibiting variable functions and thereby creating a variety of printed documents.

[Summary of the Invention] In this invention, document information to be output is output in units of rows.
a first specification means for selecting and specifying one of a plurality of line break pitch values having plus/minus signs indicating the line feed direction; and a second specifying means for selecting and specifying one of a plurality of character magnifications for each line of the document information. Two designation means are provided. During printing, the pattern of the printed document is developed at the magnification specified by the second specifying means, and the lines of the developed print document pattern are expanded once or in multiple times depending on the magnification. printed. At this time, the line printing paper feed amount required to print the line of the print document pattern is determined based on the above magnification. Further, the line feed pitch value specified by the first specifying means is converted into a line feed paper feed amount proportional to the above-mentioned magnification. Then, each time the corresponding line is printed, the printing paper is fed in the direction indicated by the sign of the difference between the line feed paper feed amount and the line printing paper feed amount by the absolute value of the difference, and a line feed is executed.

”).

Next, the operation of one embodiment of the present invention will be explained.

In this embodiment, print control by cpu io is as follows:
This is carried out according to the flowchart shown in FIG.

When the operator wants to print an input document (or an edited document), the operator presses the [Print key (actually, [
[Function] key and [\] primary key. c p u i
o If the key is manually operated, check whether the [Print] key was manually operated or not (Step S1); if No, perform other key manual processing (Step 82); if YES, execute Step S3). . In this step S3, the print line pointer indicating the document line to be printed from now on is initialized to 1, and the next print start line N indicating the first line of the document lines to be printed in the next print cycle is initialized to 1. Ru. The next print start line N and print line pointer are set in registers 51 and 52 secured in the RAM 20.

After executing step S3, the CPU 10 displays a print menu (step 84). In this state, the operator can specify the left margin and vertical/horizontal printing. After this[
When the [SELECT] key is operated and the CPU 10 determines that (step S5), the CPU 10 selects the RAM 20.
The print stop flag is checked by referring to the row modification information of the Nth row of the row modification area 22 secured within the row modification area 22 (step 8B). Then, in step S7, the CPU 10 determines whether or not printing stop is designated by the print stop flag.
), if No, the document t corresponding to the Nth line? f41ii
! 21 is checked (step S8). Then, the CP tJ 10 determines whether or not the corresponding document line has no character code, that is, whether or not it is the document END (step 89). If it is not document END, the Nth line set as the next print start line is one of the document lines to be printed from now on and is not (the first line of) the document line to be printed in the next print cycle. From, CP tJ
10 sets a new next printing start line N by adding 1 to N (step 510). When step S10 is executed, the process returns to step S6, and the above-mentioned processing (determination of presence or absence of print stop designation, determination of document END) is performed for the newly set Nth line.

Now, if the CP tJ 10 determines in step S7 that printing stop of the Nth line is specified, or if it determines that the document END is determined in step S9, it performs the calculation of N-1, and prints the result in the current print cycle. The number of print lines M indicating the number of lines of the document to be printed (note that this is not the number of lines as a print result) is determined (step 511).

This number of print lines M is determined by the register 5 secured in the RAM 20.
Set to 3. Next, the CPU 10 determines whether lCM is O or not (step 812), and if it is M-0 (because there is no print line), the CPU 10 ends print control. On the other hand, if it is not M-0, the CPU
10, in preparation for printing, first extracts the line modification information of the first line indicated by the print line pointer from the line modification area 22 (step 513). Next, CPU 10 performs the actual line break IT
Step 814 is executed to determine .

In step 814, first, based on the character size information in the line modification information, the number m of vertical dots and the number m' of horizontal dots of a character of the size specified by the information are determined, for example, from a character size table prepared in the ROM 12 (Fig. (not shown), 24
Magnification based on double-width characters of x24 dots (vertical magnification m/
24. The lateral magnification m'/24) is determined. Similarly, based on the line pitch information in the line modification information, line breaks based on the full-width character specified by the same information! (n/120. unit; inch) is, for example, a line feed amount table prepared in the ROM12 (
(not shown). Then, by multiplying the line feed In/120 by the vertical magnification m/24, the actual line feed I for the character string of the specified character size (character magnification)
T is determined and the register 54 is secured in the RAM 20.
is set to At this time, the line feed amount T may be determined by further multiplying by a proportionality constant k.

Note that the reason why the line feed amount indicated by the line pitch information is expressed in the format n/120 is because the paper feed unit of the printer 43 in this embodiment is 1/120 (inch). Therefore, n/120 indicates paper feed by n units. Similarly, the line feed amount T (m·n/24)/120 indicates line feed paper feeding by (m−n/24) units proportional to the designated magnification. However, n/120. (m-n/24)/120 is not an integer, so actually the n part of n/120, (
Only the (m-n/24) part of m-n/24)/120 is stored in the table in the ROM 12 and the register 54 in the RAM 20.

In this embodiment, n has a plus/minus sign indicating the line feed direction, as is clear from FIG.

Note that the above m, m'', and n may be set in advance in a print control program instead of in a table.

Now, the number of dots in the print head of the printer 43 is 24 dots, which corresponds to the number of vertical dots in a full-width character.

For this reason, character strings such as enlarged characters having more than 24 vertical dots cannot be printed by driving the print head for one line, and must be printed in several batches. Therefore, in this embodiment, the number S of slices of the character (character pattern) to be printed is determined, assuming that 24 vertical dots are one slice (step 515). This number of slices S is determined based on the specified character magnification and furthermore, the character form, but here, for simplicity, it is assumed that it is determined from the magnification m/24. However, m/
If 24 is not an integer, the integer greater than and closest to that value is used. For example, m-32 (
size 2), S=2 is adopted.

The number of slices S obtained in step 815 is
It is set in register 55 reserved within 0. CPU
10, upon completing step $15, initializes the slice number pointer L to O, which indicates the slice to be printed in the print head driving operation for one line. L=O indicates the first slice.

Next, the CPU 10 first prepares, for example, in the ROM 12, character spacing (n-dots) based on the full-width character specified by the same information, based on the character spacing information in the line modification information of the first line. n
By multiplying ' by the horizontal magnification m-/24, the actual character spacing U (unit: two dots) proportional to the magnification is determined (step 517). This character amount interval U is set in a register 61 secured within the RAM 20.

When the CPU 10 executes step 317, the CPU 10 sets the number of characters in the character string in the first line (in the document area 21) indicated by the print line pointer as the number of print characters in the first line in the register 57 in the RAM 20 ( step 818). Then, c p u io initializes the in-line character pointer P to 1 (first character digit), which specifies the character position (character digit) of the next character to be extracted from the character string in the th line (step 519). . This character pointer P is set in register 58 in RAM 20.

Next, the CPU 10 transfers the character pattern of the slice L (L-0) of the character (first row, Pth column) specified by the print line pointer and the character pointer P (P-1) to the print image area in the RAM 20. In order to write to the print image area 26, a write start address Q within the print image area 26 is determined taking into account the left margin (step 520). This write start address Q (
If a left margin of 8 times d is required, the relative address within the print image area 26 will be 3d, as understood from the configuration of the print image area 26 described below. The write start address Q is the register 59 in RAM 20.
is set to

FIG. 5 shows the configuration of the print image area 26 when the print head is driven for one line (one slice print area).
This is shown schematically. As is clear from the figure, addresses O to 3 of the print image area 26 (print image area 2G
The inner relative address) corresponds to each area obtained by dividing the 0th dot row (24 dots) of the print area for one slice into three parts in units of 8 dots (1 byte). In general, addresses 3n and 3n+1.3n+2 (relative addresses within the print image area 26) of the print image area 26 correspond to the nth dot row (24 dots) of the print area for one slice in units of 8 dots (1 byte). It corresponds to each area divided into three. Therefore, if a left margin of 8 d-hifts is required, the write start address Q will be <36 as described above.

When the CPU 10 executes step 820, the CPU 10 first obtains the write end address R in the print image area 26 of the character pattern of the slice L of the character in the P-th row and P-th column (step 5).
21). This write end address R corresponds to the first 8 bits of the final dot string of the character pattern of slice L. In this example where the number of horizontal dots is m', the write start address Q is set to 3 (m--1). It is found by adding. The write end address R is the register 60 in the RAM 20.
is set to

After finding the write end address R, cpu io compares the same address R with the write end address LE, and determines whether R is larger than LE (step 52).
2). This final write address LE indicates the first eight dots of the final dot row (ie, print boundary) of one slice printing area, as shown in FIG. 5, for example. Therefore, from step $22, it is possible to determine in advance whether or not a part of the character pattern of the slice L of the character in the Pth row and Pth column exceeds the printing boundary.

The significance of step S22 above will be specifically explained with reference to FIG. 6 and FIGS. 7(a) and (b). now,
Assume that the character pattern of the character in the Pth row and the Pth column is an enlarged character pattern with a 48x48 dot configuration as shown in Figure 6, due to the specification of the line pitch information (size 5) in the corresponding row modification information. . Now, consider a case where, for example, a character pattern of slice O in the enlarged character pattern shown in FIG. 6 is written in the print image area 26. If the write end address R for the character pattern in slice 0 (same goes for the character pattern in slice 1) is not greater than the end write address LE, the storage state of the pattern in the print image area 26 will be as shown in FIG. 7(a). Therefore, when the contents of the print image area 26 are printed, the above pattern will not exceed the print boundary. On the other hand, if the writing end address R for the character pattern of slice 0 (the same applies to the character pattern of slice 1) is larger than the writing end address LE, the storage state of the pattern in the print image area 26 is as shown in FIG. 7(b). As shown, when the contents of the print image area 26 are printed, part of the character pattern is missing because part of the pattern exceeds the print boundary. That is, in step 822, it is determined in advance whether or not the pattern will be printed without being missing if the enlarged character pattern is unconditionally written in the print image area 26. Note that the final write address LE is not limited to the print boundary fixed to the apparatus as described above, but may correspond to a print range specified by the operator, such as the right margin, for example. In this case, step 822 determines in advance whether or not the enlarged character pattern will be printed without exceeding the printing range if the enlarged character pattern is unconditionally written in the print image area 26.

If the determination in step 822 is No, the CP Ll 10 retrieves the character (character code) in the Pth column of the first row specified by the print line pointer and the character pointer P from the document area 21 (Step 523), and retrieves the same character. Determine whether the code is a newline code (no pattern writing required) (
step 524). If it is not a line feed code, it is necessary to write a pattern, so set the character pointer P by +1.
and advance to the next character position (step 3-25).
, the character pattern corresponding to the character code taken out in step 323 is taken out from the character pattern area 16 in the ROM 12 (step 826). The character pattern stored in the character pattern area 16 is 24 x 24 dots (72
It is a double-byte character pattern with a byte) configuration. The character pattern taken out from the character pattern area 16 is temporarily stored in a predetermined one character storage area (not shown) in the RAM 20.

When the CPU 10 executes step 826, it first determines whether or not a change in character size or character form is requested based on the line modification information of the line, that is, whether or not conversion of the character pattern is required (step 527).

If pattern conversion is required, CPU 10
Character pattern in character storage area (i.e. original character pattern)
(step 828), and if pattern conversion is not necessary, skip step 828, and then convert the character pattern of the slice number (i.e., sliced) indicated by the slice number pointer L. (If step 828 is skipped, since it is a full-width character, it becomes a character pattern in the 1-character storage area) in order into the area starting from the relative address in the print image area 26 indicated by the write start address Q. (Step 529).

When CPU IO executes step 829, by adding three times the character spacing (dots) to the write end address R, the write start address Q is set to start writing of the next character (one slice of the character). The same address Q is updated to indicate the address (step 530). This achieves the character spacing of U dots. The character amount interval U is obtained in step S17 as described above, and
The character spacing is not based on the full-width characters specified in the font size information, but is obtained by multiplying this specified character spacing by the magnification (horizontal magnification) (specified in the font size information), that is, it is proportional to the magnification. This is the actual character spacing. Therefore, in this embodiment, while specifying the character spacing based on the image of full-width characters, the character spacing that matches the actual character size is automatically realized.

When the CP IJ 10 executes step 330, it increments the number of printed characters V by 1 (step 531), and determines whether V has become O (step 532). If ■ is 0
If not, c p u io assumes that unprocessed characters remain in the first line and returns to step S21.

On the other hand, if -0, the CPU 10 assumes that all the characters in the first line have been extracted and the corresponding character pattern (the character pattern of slice L) has been written in the print image area 26, and starts from step 833. First, the process moves on to control the printer 43 for printing the first line. The process starting from step 833 is performed even if the result is not V-0, if the determination in step 822 is YES (that is, if the write end address R is greater than the final write address LE), or if the determination in step 324 is YES. This is executed both when the character code extracted from the document area 21 is a line feed code, and when printing of the corresponding character in the Pth column of the corresponding row is prohibited or unnecessary.

The CP Ll 10 first determines whether the character pointer P indicates 1, that is, whether step 825 of adding 1 to P has not been executed even once (step 53).
3). If it is not P-1, the CPU 10 determines that the first character of the line is not a line feed code (that is, it is not a complete line feed).
That is, it is determined that the character pattern to be printed is written in the print image area 26, and the printer 43 is controlled to print the contents of the print image area 26 (step 534). Next, the CP LJ 10 clears the print image area 26 (step 535) and subtracts the number of slices S by 1 (step 536). Then, the CPU 10 determines whether the number of slices S is O, that is, whether printing of the character string in the first row has been completed (step 531).

If the determination in step 837 is No, the CPU 10 determines that the printing of the first line has not finished, and first increments the slice number pointer L by 1, and specifies the slice number of the next slice to be printed. (step 838).

Then, the CPU 10 controls the printer 43 to spread the printing paper as many times as the print head (full-width character The paper is fed in the forward direction by the length of the vertical dot (step 539). As mentioned above, the paper feed unit of the printer 43 is 1/120 (inch).
The dot configuration of the print head is 24 dots, and 3 dots are 2/120 inch. Therefore c p
u io is 16/120(
This causes the printer 43 to feed the paper in the forward direction (inches). c p u io is step 839
Once executed, the process returns to step 818, and the process for printing the next slice is performed for the same character string in the first line as the previous time.

On the other hand, if the determination in step S37 is YES, that is, if the printing of the character string in the first line is completed and the number of slices S becomes 0, c p u io uses the L The value obtained by multiplying
>/120 and set the result as the new line feed amount T (step 340).

This newly obtained absolute value of the bottom of the line feed indicates the paper feed amount (in inches) for the line feed paper that should be carried out after the first line is printed, and the sign (plus/minus sign) is the paper feed direction. shows. As is clear, when the second line is full-width characters (size 1), L remains O (that is, the printing paper feed in step 339 is not executed), so the newly determined T is It matches T determined in step 814.

When the CP LJ 10 executes step 840 or determines YES (P=1>) in step 833,
In order to determine the paper feed direction, it is determined whether the line feed IT is greater than or equal to 0 (that is, whether the paper is being fed in the forward direction) (step 541). Note that when the determination in step S33 is YES, the printing execution in step 834 is skipped because the first character of the line is a line feed code and becomes a complete line feed.

c p u io causes the printer 43 to forward paper feed by T inches if ■≧0 (step 54
2) If T<O, the printer 43 is caused to feed the paper in the reverse direction by the absolute value of T (step 543). As a result, the actual line feed pitch is determined by the ratio of the line feed pitch and the character size (number of vertical dots) of the printed characters on the second line to the line pitch (line feed pitch) based on the full-width character specified by the line pitch information. This is realized so as to match the ratio between the number of vertical dots and the number of vertical dots of a full-width character. That is, in this embodiment, while specifying the line pitch (line feed pitch) based on full-width characters, it is possible to realize a line pitch proportional to the size of characters specified by the character size information. Note that the determination in step 833 is YES.
In this case (that is, in the case of a complete line break), since printing is not executed, T obtained in step 814 is used as is.

Now, in this embodiment, the line pitch information is B, O,
Nine types are available: H, E, 1 to 4 (see Figure 3).

Line feed B (reverse line feed, back line feed) specifies a line feed in the opposite direction by 8/120 (inch) based on full-width characters. In this case, the paper feed amount after printing the character string in the first line is calculated from the line pitch (minus value) for the character string of the specified character size, which is obtained by multiplying -8/120 (inches) by the vertical magnification. Paper feed required to print! (total set feed amount of paper feeds performed to print the same character string) is subtracted, and the paper feed direction is the opposite direction since the result of the subtraction is negative. Therefore, when line feed B is specified, a reverse line feed of 1/2 character of the character size specified by the character size information is realized.

Line feed O (line pitch 0) specifies a line feed amount of 0.

In this case, the paper feed amount after printing the character string in a row is the paper feed amount required to print the same character string (the total paper feed amount of the paper feeds performed to print the same character string). corresponds to the absolute value,
The paper feed direction is the opposite direction.

Therefore, when line feed 0 is specified, line pitch O (O line feed) is realized regardless of the character size specified by the character size information. In addition, when the number of vertical dots is 24,
Since the total paper feed amount during printing is O, the paper feed poison after printing is also O.

Line feed H (half line feed, half line feed) specifies that a line feed is to be made in the forward direction by 8/120 (inch) when using full-width characters as the standard. In this case, the feed end after printing the character string on the first line is +8/120 (inches) multiplied by the vertical magnification '?
; Subtract the paper feed amount required to print the same character string (the total paper feed amount performed to print the same character string) from the line pitch for the resulting character string of the specified character size. This is the absolute value of the value, and the paper feed direction is the direction indicated by the sign (positive/negative) of the subtraction result. Therefore, when a line feed H is specified, a forward line feed (half line feed) of 1/2 characters of the character size specified by the character size information is realized.

Line feed K (ruled line feed, line feed by one character) specifies that the line should be broken in the forward direction by 16/120<inches, based on full-width characters. In this case, the paper feed amount after printing the character string in the first line is determined from the line pitch for the character string of the specified character size, which is obtained by multiplying +16/120 (inches) by the vertical magnification. The value obtained by subtracting the required paper feed amount (the total paper feed amount of the paper feeds performed to print the same character string), that is, 16/120 (inches), and the subtraction result is positive in the paper feed direction. Therefore, the direction is forward. In this case, if the vertical magnification is an integer, the specific paper feed urn will be the character size of the magnification 1, that is, 16/120 (inches), and will be a fixed amount. On the other hand, if the vertical magnification is not an integer, the forward paper feed amount is equal to the character size of the magnification indicated by the decimal part of the vertical magnification.

Therefore, when a line break K is specified, a line break with only character valves of the font size specified by the character size information, that is, a line break with a line spacing of O is realized.

For this line break, since the line spacing can be set to 0 as described above, that is, the first character string of the first character size and the second character string of the second character size that follows the same character string. Since it is possible to connect lines without gaps, it is suitable for creating enlarged ruled lines (particularly vertical ruled lines), for example. In addition,
When creating horizontal ruled lines, the character spacing may be set to 0.

Also, line feed E (English line feed) specifies a forward line break of 20/120 (inches) when using full-width characters as the standard, and line feeds 1.2 and 3.4 specify line breaks in the forward direction by 20/120 (inches) when using full-width characters as the standard. 30/120.40/120.45/120.6
Specifies forward paper feed of 0/120 (inch).

The above specific examples are shown in FIGS. 8 to 10.

Figure 8 shows an example of document printing when the same values are specified for character spacing and line pitch (line feed amount) for each document character string, but different values are specified for character size.
This diagram corresponds to (part of) the contents of the document area 21 and the line modification area 22.

In FIG. 8, line break pitches Ll, L2, . L3 has a value proportional to the character size (m magnification) even if the same line feed amount (line feed 1) is specified in both cases. Similarly, the character spacing P1 for character strings with character sizes 1 and 2.3. Even if the same character spacing of 2 (6 dots) is specified for both, P2 and P3 have values proportional to the character size (horizontal magnification).

FIG. 9 shows an example of printing when a line feed O is used to shade full-width characters and quadruple-width characters, corresponding to the contents (parts) of the document area 21 and line modification area 22. In this embodiment, the hatching pattern is prepared independently as one character. In this case, prepare a character code A for the first row and first column of the document, a shading code for the second row and first column, set the line pitch to 0 for the first line, and set the font size to When full-width characters are specified in the first and second lines, a half-width pattern of the same size is printed in the second line, overlapping the character A printed in the first line. If you want to shade a large number of strings,
All you have to do is input a string of shading codes and set the character spacing to O. The above also applies to enlarged characters such as quadruple-width characters.

Figure 10 shows a printing example of the contents of the document area 21 and line modification area 22 (partially ).

Now, CPU10 performs step 842 or step 84.
When the paper feed of 3 is executed, the number of print lines M is decreased by 1 (step 844), and it is determined whether M has become O (step 545). If M is not O, there are still document lines to be printed, so the CPU 10 moves the print line pointer K
After incrementing +1 and proceeding to the next document line (step 846)
, the process returns to step 813. On the other hand, if M is O, CPU io first determines whether printing stop was specified in the line modification information of the th line (step 54).
1). If printing stop is specified, CP tJ
Step 10 returns to step $4 and displays a print menu. This allows the operator to change the color type by replacing the print ribbon used for printing by the printer 43, change the left margin value, and change settings for vertical/horizontal printing.

If stop printing is not specified for this, c p
uio determines whether printing of the document in the document area [21 has been completed, and ends print control.

[Effects of the Invention] As detailed above, according to the present invention, a specified line break pitch value is converted to a value according to the font size and the actual line break amount is controlled, thereby creating a line break that is commensurate with the font size. The pitch can be realized without putting a burden on the operator, and a well-balanced printed document that takes character size into consideration can be easily created. Further, according to the present invention, the line feed pitch value that is selected and specified has a plus/minus sign that defines the line feed direction, and when realizing the line feed amount according to the character size, the character size is controlled even in that direction. Since variable functions can be fully utilized, a wide variety of printed documents can be created.
