Abstract

PURPOSE:To form versatile printed documents by enabling the print starting position of the following line to be restored to a position where the interval between the print starting positions of corresponding printing line, or a position preceding the corresponding printing line, is proportional to the letter sizes by a method in which printing paper is fed to the opposite direction only by the absolute value for difference between the paper feeding amount for line feeding and the paper feeding amount for line printing. CONSTITUTION:For the document former, nine kinds of line-pitch information, B, O, H, K. E, 1-4 are provided. In the case of line-feeding B, when em-letter is the basis, indication is made to make line feeding to the opposite direction only for 8/120 inches. In this case, the feeding amount of paper after printing letter row of k-line becomes an absolute value obtained by deducting a paper feeding amount necessary for printing the letter row from pitches for the letter row of indicated letter size obtained by multiplying -8/120 inches by a vertical magnification, and oppositely directed line feeding only for 1/2 of letter size is realized. When superscript letter for 4-magnified em-letter is formed by em- letter by using the line-feeding B, it is shown by Fig. I.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a document creation device with a print character size variable function.

[Technical background of the invention and its problems] Recent document creation devices such as Japanese word processors have
Many printers now allow variable print font size.

Conventionally, there has been no known document creation device of this type that is capable of printing the next line by starting a line in the opposite direction to an enlarged character line.

[Object of the Invention] This invention has been made in view of the above circumstances, and its purpose is to include a backward line feed pitch value having a negative sign as one of the line feed pitch values that can be selected and specified. If specified, the printing start position of the next line is determined by feeding the printing paper in the opposite direction by the absolute value of the difference between the line feed paper feed amount and the line printing paper feed amount each time the corresponding line is printed. To provide a document creation device capable of returning to a position preceding a relevant print line and having an interval from the print start position of the relevant print line in proportion to the character size, thereby creating a variety of printed documents. There is a particular thing.

[Summary of the Invention] In this invention, document information to be output is output in units of rows.
a first specifying means for selecting and specifying one of a plurality of line feed pitch values including a backward line feed pitch value having a negative sign; and a second specifying means for selecting and specifying one of a plurality of character scaling factors for each line of the document information. Two designation means are provided: a designation device and a designation device. At the time of printing, the pattern of the print document is developed at the magnification specified by the second specifying means, and the lines of the developed print document pattern are printed once or in multiple times depending on the magnification. be done. 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. When the backward line feed pitch value is specified by the first specifying means, the printing paper is moved in the reverse direction by the absolute value of the difference between the line feed paper feed amount and the line printing paper feed amount each time the corresponding line is printed. By feeding, a reverse line feed is executed to return the print start position of the next line to a position preceding the print start position of the corresponding line.

The above-mentioned line modification information can be interactively set for each line by the operator operating keys on the keyboard 33 while looking at the display screen of the display 37. For example, to set font size information, display the font size screen by key operation, and specify one of the numbers 1 to 9 on this screen (actually two screens, 1 to 5 and 6 to 9) with a key. I can do it. Further, setting of the character spacing information is performed by displaying a character spacing screen by key operation and specifying one of the numbers 0 to 3 on this screen with a key. Similarly, to set the line pitch information, display the line pitch screen by key operation,

1 for 45 dots in this example, which is 0 inches (this value is the displayed character on the screen, and is actually 0100")
It is.

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

In this embodiment, the print control by CPLllo is performed by the fourth
The process is carried out according to the flowchart shown in the figure.

When the operator wants to print the input document (or edited document), the operator presses the [Print] key (actually, the [Print] key on the keyboard 33).
[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 printing start line N and the printing line pointer are set in registers 51 and 52 secured in the RAM 20.

After executing step S3, the CP LJ 10 displays a print menu (step 84). In this state, the operator can specify the left margin and vertical/horizontal printing. After this, the [Select] key is operated, and the CPU 10
(step S5), the CPU 10 uses the RAM 2
The line modification information of the Nth row of the row modification area 22 secured within 0 is referred to and the print stop flag is checked (step 86). Then, in step 8, the CPU 10 determines whether or not printing stop is designated by the print stop flag.
7) If No, check the document line in the document area 21 corresponding to the Nth line (step 88). and c p
ui.

is whether there is a character code in the corresponding document line, that is, document E
It is determined whether or not it is ND (step S9). 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 there, c p u io increases N by 1 and sets a new next print start line N (step 510).
. When step S10 is executed, the process returns to step S6,
The above processing (determination of presence/absence of print stop designation, determination of document END) is performed for the newly set Nth line.

Now, if the CP Ll 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 determines the print stop for 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 set in a register 53 secured within the RAM 20. Next, the CPU 10 determines whether M is O (step 812>, M-0
If so (because there are no print lines), CPLJlo ends print control. On the other hand, if it is not M-0, CP
In preparation for printing, the Ll 10 first retrieves the line modification information of the first line indicated by the print line pointer from the line modification area 22 (step 513). Next, cpuio executes step 814 to determine the actual line feed amount T.

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 from a character size table prepared in the ROM 12, for example. (not shown), 2
Magnification based on 4x24 dot full-width characters (vertical magnification m
/24. The lateral magnification m'/24) is determined. Similarly, based on the line pitch information in the line modification information, the line feed amount (n/120. unit; inch) based on the full-width character specified by the same information is calculated using the line feed amount table prepared in the ROM 12, for example.
(not shown). Then, by multiplying the line feed amount n/120 by the vertical magnification m/24, the actual line feed amount T for the character string of the specified character size (character magnification) is calculated, and the register 54 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 feeding 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) portion 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 can 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 (
If size 2 is specified), S-2 is adopted.

The number of slices S obtained in step S15 is RAM
It is set in a register 55 reserved in 20. C.P.
When U 10 completes step $15, it initializes slice number pointer L to O, which indicates the slice to be printed in the print head driving operation for one line. L-0 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 817, the CPU 10 sets the number of characters of 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 second line in the register 57 in the RAM 20 (step 818 ). and c
p u io first 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 5).
19). 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 for d dots 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 set in the register 59 in the RAM 20.

FIG. 5 schematically shows the configuration of the print image area 26 corresponding to the print area (one slice print area) when the print head is driven for one line.As is clear from the figure, the print image area 2G is Addresses O~3 (Print image area 26
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 d dots is required, the write start address Q will be <36 as described above.

When CPU IO executes step 820, it 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 Pth column in the 1st row (Step 521). This write end address R corresponds to the first 8 pits of the final dot row 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>). The write end address R is determined by adding the write end address R to register 6 in RAM 20.
Set to 0.

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 S22, it can be determined in advance whether a part of the character pattern of the slice L of the character in the P-th row and the P-th column exceeds the printing boundary.

The significance of step 822 above will be specifically explained with reference to FIG. 6 and FIGS. 7(a) and 7(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, the character pattern of slice 0 of 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 of slice O (the same applies to the character pattern of 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 O (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, step S22 is to determine in advance whether or not the enlarged character pattern will be printed without being missing when 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, the stamp 822 determines in advance whether or not the enlarged character pattern will be printed without exceeding the print range when the enlarged character pattern is unconditionally written in the print image area 26.

If the determination in step S22 is NO, the CPU 10 sets the print line pointer and retrieves the character (character code) in the Pth column of the first row designated by the character pointer P from the document area 21 (step $23); It is determined whether the character code is a line feed code (which does not require pattern writing) (step 524). If it is not a line feed code, it is necessary to write a pattern, so after incrementing the character pointer P by 1 and advancing to the next character position (step 825), write the character pattern corresponding to the character code extracted in step 823 into the ROM 12. Extract from the character pattern area 16 in (
step 826). The character pattern stored in the character pattern area 16 is a full-width character pattern composed of 24×24 dots (72 bytes). Character pattern area 1
The character pattern extracted from 6 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)
is successively converted into a character pattern of the specified size or form (step 828), and if pattern conversion is not required, step 828 is skipped, and then the character of the slice number (i.e. slice, L) indicated by the slice number pointer L is converted. The pattern (if step 828 is skipped, since it is a full-width character, it will be a character pattern in the 1-character storage area) is written in order in the area starting from the relative address in the print image area 26 indicated by the write start address Q. (step 529).

When CPU 10 executes step 829, by adding three times the character interval U (dot) to the write end address R, the write start address Q changes to the next character (
The same address Q is updated to indicate the write start address for one slice of the data (step 530). This achieves the character spacing of U dots. The character spacing U is
As mentioned above, it is obtained in step 817, and is not a character spacing based on full-width characters specified by the font size information, but a magnification (horizontal magnification) (specified by the font size information) for this specified character spacing. ), that is, the actual character spacing that is proportional to the magnification. 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 cpuio executes step 830, it decrements the number of printed characters by 1 (step 831), and determines whether V has become 0 (step $32). If ■ is not 0, the CPU 10 assumes that unprocessed characters remain in the first line and returns to step 821.

On the other hand, if ■=O, 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 ■-o is not the case, if the determination in step S22 is YES (that is, if the write end address R is greater than the final write address LE), or if the determination in step S24 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 CPU-10 first determines whether the character pointer P indicates 1, that is, whether step S25 of adding 1 to P has not been executed even once (step 533).
. If it is not P-1, the CPU 10 first determines that the first character of the line is not a line feed code (that is, not a complete line feed), that is, determines that the character pattern to be printed has been written in the print image area 26. and printer 43
to print the contents of the print image area 26 (
Step 534). Next, the CP Ll 10 clears the print image area 26 (step 535), L, and then subtracts the number of slices S by 1 (step 836). C
p u io 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 537).

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 part 3
The dot portion is 2/120 inch. Therefore, C.P.
In step 839, U 10 receives 16/120 (
This causes the printer 43 to feed the paper in the forward direction (inches). After executing step 839, the CPU 10 returns to step 31B and performs processing for printing the next slice regarding the character string in the same row as the previous time.

On the other hand, if the determination in step S37 is YES, that is, if printing of the character string in the first line is completed and the number of slices S becomes 0, the CPU 10 executes the L The value obtained by multiplying by 16/120 (i.e., the amount of paper feed required to print the character string in the first line) is T, i.e. (m-n/24)
/120 and set the result as the line feed amount T (
step 540).

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, if the first line is full-width characters (size 1), shi remains 0 (that is, the printing paper feed in step 839 is not executed), so the newly determined T is This matches T determined in S14.

When CP LJ 1G executes step 840 or determines YES (P-1) in step 833, it determines whether the line feed amount T is greater than or equal to 0 to determine the paper feed direction (i.e., if the paper in the forward direction (step 541). Note that the determination in step 833 is Y.
In the case of ES, 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.

If T≧0, the CPU 10 causes the printer 43 to forward paper feed by T inches (step 542).
), 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 if the determination in step S33 is YES (that is, in the case of a complete line break), printing is not executed, so the T determined 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. It is the absolute value of the value obtained by subtracting the paper feed amount required to print (the total set feed amount of paper feeds performed to print the same character string), and the subtraction result is negative in the paper feed direction. Therefore, it is in the opposite direction. 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 O) is a line feed! Specify i0.

In this case, the paper feed amount after printing the character string in the first row is the paper feed amount necessary to print the same character string (the paper feed amount of the paper feed 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 paper feed amount during printing is 0, the paper feed amount 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 paper feed amount after printing the character string in the first line is calculated from the line pitch for the character string of the specified character size, which is obtained by multiplying +8/120 (inches) by the vertical magnification.
It is the absolute value of the paper feed amount required to print the same character string (the paper feed amount of the paper feed performed to print the same character string), and the paper feed direction is the result of the subtraction. The direction is indicated by the sign (positive/negative). 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 is 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 paper feed amount of the paper feed 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, when the vertical magnification is an integer, the specific paper feed amount is equal to the character size of magnification 1, that is, 16/120 (inches), and becomes a fixed layer. 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 for the number of characters of the font size specified by the character size information, that is, a line break with a line spacing of O is realized.

Since this line break can have a line spacing of O 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 line break in the forward direction by 20/120 (inches) based on full-width characters, and line feed 1.2.3.4 specifies line feed in the forward direction by 20/120 (inches) when based on full-width characters. 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.

FIG. 8 shows an example of document printing when the same values are specified for the character spacing and line pitch (line feed amount) for each document character string, and different values are specified for the character size. This is shown in correspondence with (a part of) the contents of the line modification area 22.

In FIG. 8, line break pitch L1. L2. L3 has a value proportional to the character size (vertical magnification) even if the same line feed amount (line feed 1) is specified in both cases. Similarly, the character amount interval P1 of a character string with a character size of 1.2.3. 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 a printing example when line feed 0 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 the character code A for the first row and first column of the document, and the shading code for the second row and first column, and for the line pitch, for example, specify line break O in the first line, and set the font size. 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, when the CPU 10 executes the paper feed in step S42 or step 843, it increments the number of print lines M by 1 (step 544), and determines whether M has become O (step 545). If M is not O, since there are still document lines to be printed, the CPU 10 increments the print line pointer K by 1 and advances to the next document line (step 846
), the process returns to step 813. On the other hand, M is O
If so, the CPU 10 first determines whether or not printing stop was specified in the line modification information of the th line (step 547).
. If printing stop is designated, the CPU 10 returns to step S4 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 is finished, and ends printing control.

[Effects of the Invention] As detailed above, according to the present invention, one of the line feed pitch values that can be selected and specified includes a backward line feed pitch value having a negative sign, and the backward line feed pitch value is specified. In this case, by feeding the printing paper in the opposite direction by the absolute value of the difference between the line feed paper feed amount and the line printing paper feed amount each time the corresponding line is printed, the printing paper is advanced from the printing start position of the corresponding line, and the corresponding line is Since the printing start position of the next line can be returned to the position corresponding to the font size, a variety of printed documents can be created.
