Abstract

PURPOSE:To make the column and row conversion printing in a unit of line of the document having different spaces between letters including the underline and the ruled line possible, by possessing a means of drawing a underline under the letter space part and a means of drawing a ruled line to the letter space part. CONSTITUTION:Whether line feed code or not is judged. If no line feed code, whether the ruled line connection bit is on or not, is determined. If the ruled line connection bit of LIB is on, a horizontal ruled line code is set to a letter code. If the ruled line connection bit of LIB is not on, a letter pattern is immediately loaded from ROM and the LIB zone sequence number is loaded. Then, the letter is enlarged to be processed from line modification information such as letter size, rotation, inclined type, letter void, etc. and the zone sequence number. Thereafter, whether vertical ruled line code or not is judged, if no vertical ruled line code, the process is ended. Further, if vertical ruled line code, a vertical ruled line pattern is developed between lines and the process is ended. Furthermore, if it is judged to be a line feed code, a specific value indicating the printable maximum dot number is set at the line feed position of LIB and process of letter development is ended.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a print control system for a document creation device that realizes a vertical/horizontal conversion printing function for a line-modified document.

[Technical background of the invention and its problems] Conventionally, document creation devices such as Japanese word processors use a CRT display as a document display mechanism and an external storage such as a floppy disk device as a document file mechanism. The structure was large and expensive. However, in recent years, LCD (Liquid Crystal Display) is used as the display mechanism, and CMT is used for document file $11IA.
Various innovations and improvements have been made, such as using a cassette-type magnetic tape device or a micro-floppy disk drive, and a document creation device called a personal word processor, which is small, light heat, and low cost, has been realized. It's arrived.

In such low-cost and compact document creation Vt devices, for example, there are major restrictions on the display screen size of the LCD that serves as the input mechanism.
A screen with a small screen size of letters or several crosses is used.

In addition, the printing mechanism is also subject to significant restrictions on the paper size that it can handle; for example, providing a printing mechanism that can insert 84-size paper horizontally into the paper feed section would increase the size and weight of the device. This will lead to increased costs and higher prices, making it impossible to achieve the intended purpose.

Therefore, a so-called portrait-horizontal conversion printing method has been realized, which allows printing even when B4 paper is inserted vertically in the same manner as when it is inserted horizontally.

However, in printing using the normal printing method, the printable range in the column direction of the paper is limited by the printable range of the print filter structure, whereas in printing using the above-mentioned aspect conversion printing method, the printable range in the row direction of the paper is limited. limited. Figure 17 shows the printing forms for standard printing and portrait/horizontal conversion printing at this time.
a> to (d). That is, the figure (a) is standard/horizontal printing, the figure (b) is the standard/vertical old m1 format, the figure (C) is the vertical/horizontal conversion/horizontal printing, and the figure (d) is the vertical/horizontal conversion/vertical printing. Each form is shown.

Therefore, conventionally, when printing by aspect conversion printing,
Even if the line pitch is fixed or variable, if a line pitch exceeding the printable range is specified, printing is not executed at all. In addition, in conventional aspect conversion printing, not only the line pitch mentioned above, but also character size, character spacing, line spacing, etc. are fixed, so when performing aspect conversion printing, the print result is completely different from normal printing. had.

[Object of the invention] The present invention has been made in view of the above-mentioned circumstances.
The purpose is to provide a print control method that can print documents containing a mixture of multiple types of characters with vertical and horizontal conversion so that the print result is similar to that of normal printing. The purpose of the present invention is to provide a print control method that can perform vertical/horizontal conversion printing including ruled lines.

[Summary of the Invention] The present invention is capable of determining the font size, character size, and
A line modification storage means that stores modification information including the spacing between characters, and a line break position, column number,
a line information storage means for storing line information including a zone number, an underline connection bit, and a ruled line connection bit; a means for updating the line break position of the line information according to the inter-character spacing of the line modification information; A means for obtaining a line feed value that determines the paper feed amount from the line feed position, a means for underlining the space between characters using the underline connection bit of the line information, and a means for drawing a ruled line between the characters using the line connection bit of the line information. The device is equipped with a means for printing documents with different character spacing line by line, including underlines and ruled lines, on a sheet of paper inserted vertically into the paper feed section of the printing mechanism, just as if the sheet were inserted horizontally. It is configured to be able to print horizontally and vertically.1.In a personal word processor, it is possible to effectively utilize the narrow paper feed area and print a sentence containing multiple types of characters line by line as usual. It is possible to perform portrait/horizontal conversion printing so that the printing result is similar to that of the original, and the printing function can be greatly improved.

Note that to specify document printing, on the actual machine, the document printing instruction is entered by pressing a specific second character key while holding down the [ta function] key. To simplify the explanation, it is assumed that the document print mode is specified using the document print key. Also, here, it is possible to partially print an arbitrary number of lines even during document creation, and this partial printing is also specified in combination with a specific key that is the [Function] key.

Under these print modes, settings such as [Standard printing/Vertical/horizontal conversion printing], [Horizontal writing/Vertical writing], [Left margin 6 spaces], etc. can be specified using the cursor keys and numeric keys and the [Select/Execute] key. This is done by the operation of

Here, the operation of one embodiment will be explained with reference to the above figures.

When inputting a sentence containing kanji, the key input signal from the keyboard 30 is converted into kana and kanji by the control of the CPU 11 in the 8110, and stored in the document buffer in the RAM 14.
Further, a scan signal is outputted to the keyboard 30 via the decoder 13, and the return signal is inputted to the PP12 to perform key discrimination and generate a key code. Furthermore, the dictionary in the ROM 15 and the provisional dictionary in the RAM 14 are indexed for the designated part of the kana/kanji manually inputted based on the same key code, and after the kana/kanji conversion process is performed, the converted kanji code is Store the input character code string containing the text in the statement 1 buffer.

During the above-described document input, input characters stored in the document buffer are sequentially developed into patterns on the line image buffer 140 under the control of the CPU 11, and
ill I! The signal is displayed on the LCD 50 by the display control of the 1 circuit 17 and the display drive of the LCD driver 51.

The previously inputted document thus input can be arbitrarily displayed as a character string of a predetermined number of digits on the LCD 50 by operating the cursor keys, and can be used for proofreading, correction, etc. of the document.

If you want to specify character modification on a line-by-line basis for the above input document, use the cursor keys to select and display the character string at the line position you want to modify, then press the [n] key and other specific keys. In combination with [Line modification 1 key operation specifies line modification.

When the CPU 11 determines that the [Lamp 1] key is operated, the CPU 11 switches the display mode of the LCD 50 from the document display mode to the line modification display mode. In this line modification display mode, to give a specific example, first a selection screen for selecting character spacing and line break pitch is displayed, and then a selection screen for selecting character size is displayed. At this time, change the item from character spacing to line break pitch using [Next item]
The selection screen is changed by operating the cursor keys in the up and down directions, and each item is selected by operating the cursor keys in the left and right directions. For example, when the selection screen for selecting character spacing and line break pitch is displayed, do not select the item by operating the [Next Item] key or operating the left/right cursor keys, but select by operating the up/down cursor keys. When the screen is switched, it is assumed that the character spacing displayed by the cursor on the interpretation screen has been selected, and the line modification information containing the control information is stored in the RAM 1.
The item (character size here) stored in the line modification buffer in 4 and then newly displayed on the selection screen becomes the selection target. Also, by switching the selection screen above, for example, "Stop printing"
When the selection screen is displayed and "Printing stopped" is selected by operating the cursor keys, and the [Select/Execute] key is then operated, the line modification information having the control information "Printing stopped" is stored in the RAM 14. stored in the line qualification buffer within.

In the above-mentioned line is setting means, after the line modification setting is performed for an arbitrary line position of the document stored in the document buffer, By displaying the already entered documents in the L CD 50 by operating the cursor keys,
On the guide display section on the CD 50, the line, digit, and number of characters per line of the displayed character string are displayed, and a line modification indicator is selectively displayed. That is, when a display string consisting of a cursor operation is selected, the line position, column position, and number of characters per line of the display string specified by the cursor are displayed, and the line*i buffer? The line decoration information for the corresponding row position stored in is referenced, and the same information is compared with the line decoration standard value to determine whether or not line decoration is set for the display line selected by the cursor. Ru. Here, if the line decoration is not set, that is, if the content of the above line decoration information matches the above line decoration standard value, the line decoration indicator will not be lit, and if the line decoration is set, i.e. If the content of the line modification information does not match the line modification standard value, the line modification indicator is turned on. Display control of a mouth-like line modification indicator is performed for all lines of the displayed document selected by the cursor keys. In this manner, the line position where the line modification has been performed can be easily confirmed from the lighting state of the row modification indicator.

Next, when specifying the document print mode with the above-mentioned [Document Print] key, or when specifying the partial print mode with a specific key operation for specifying [Predetermined Partial Print] The processing operation will be explained with reference to FIGS. 2 to 16.

When the document print mode is specified by the above [Document Print] key operation, or when the partial print mode is specified by a predetermined specific key operation for specifying [Partial Print], L
The display mode of the CD 50 is switched to a print information setting mode, and a selection screen for setting print information is displayed. First, a selection screen for [standard printing/vertical/horizontal conversion mark 81] is displayed. Here, when [vertical/horizontal conversion printing] is selected, a selection screen for [vertical writing/horizontal writing] and [first line position 43] is displayed next. At this time, the selection screen and selection item switching, item selection, etc. are performed using the cursor keys, [Major item] key, [Select/Execute key, etc.] in the same way as in the line modification mode described above. ] In the selection item, if no numerical value (2 digits) is set and you move to the next screen using the up/down cursor keys, here,
The pre-initialized number [The 43rd line (scale display) according to (43) is the [Print first line position] of vertical/horizontal conversion printing.
It will be set as .

Upon completion of the setting of the above print information, the CPU 11 selects the mark (iiη start line (in case of full text printing, the top of the first page, When printing part of a line, the line modification information after the cursor specified line is referred to in the printing order, and the line modification information with the information "Printing stopped" or "Paper replacement" is detected, and the printing starts from the above printing start line. After calculating the number of lines up to the detected line as the [print designated number of lines], execution of the print routine is started.

The vertical/horizontal conversion printing processing operation at this time will be explained with reference to FIGS. 2 to 16.

First, the entire processing operation of aspect conversion printing will be explained with reference to the flowchart of FIG. 11. After calculating the above-mentioned [print designated line @], the print routine is executed, and the processing shown in the flowchart of FIG. 11 is executed. At this time, if it is partial printing, first, in step S1, the above mark 1 is printed.

1” and all others to “0”, and then proceed to step S.
In step 4, the LIB line break position Pt is updated according to the "left turn margin" of the line modification information set in advance.

Furthermore, in step S5, the [Print start line number] stored in register R3 is set as [Print line number] in register R10, and the [Number of C printable lines] stored in register R2 is set as [Print line number]. Register R11 as row number 1
[Character expansion start point is set to register R12 and register R13. Next, in step S6, the minimum value of the line feed position is detected from the line feed position field bXPL of each line IB corresponding to the document to be printed, and this is set in register R9 as the [line feed execution position]. .

Next, in step S9, the line feed execution position 1 is a specific value held in register R9 that represents the maximum number of printable dots in the paper feed direction, for example, 7FFFFFFFF (H).
It is determined whether or not the number of dots has reached the maximum number of dots that can be printed, but it is not possible to print. If the maximum number of dots has not been reached, proceed to the next step S.
Execute the process in step 8.

In step S8, the [print head position] held in register R8 is subtracted from the [line feed execution position] held in register R9, and after converting the subtraction result to "inches", in step S9 Execute a line break.

After performing the above change action, in step 310,

Then, in step 80, after r-IJ the [number of remaining print lines] held in register R1, step A
In step 10, it is determined whether the above-mentioned [number of remaining lines to print] has become ○J, and if it is not [0], the process proceeds to step A11.

In this step A11, the line pitch of the characters on that line is loaded from the [print start line number] held in the register R3.

Next, in step A12, the above [print end point] is added by the above line pitch, the updated [print end point] is set in register R7, and in step A13, the [print end point] is rOJ Determine whether it is smaller.

Here, if the above [Print end point] is greater than rOJ,
In step A14, "print start line number 1 is r+1" L held in register R3, and then the process returns to step A5.

In addition, in step A7, if it is determined that the temporary printing start point is larger than the printable range, the Stellarub A15 selects the print start point held in register R3. Line number 1 is r-IJt, then,
The process starts at step A16.

Furthermore, in step A10, if it is determined that the above-mentioned [11 pages remaining to print have reached rOJ], or in step A13, if it is determined that the above-mentioned [printing end point] is smaller than rOJ, the above-mentioned step is also carried out. The process begins in A16.

In this step A16, from the above [printable range],
Reduce the [print start point] held in register R4,
The result of the subtraction is set as the [character expansion start point] in register R6.
Set to .

In step A17, the [number of lines remaining to print] held in register R1 is subtracted from the [number of lines specified to print] held in register RO, and the result of the subtraction is set as [number of lines that can be printed]. Set it in register R2 as .

This completes the data setting process for registers R2, R3, and R6, and the step $2 in FIG. 11 is completed! l! l! Let's move on to the theory.

Figure 13 shows step 11 in step $4 of Figure 11 above.
B shows the details of updating the line break position from the left turn margin.

This LIB line break position update process begins with step B1.
In step B2, the LIB top address is set in the LrB pointer, and furthermore, in step B2, the [Print start line number] is set in register R3, and register R
Set [Number of printable lines] to 2.

Next, in step B3, the paper feed direction is moved to the minimum line feed position PL(+)) which indicates the minimum value among the line feed positions PL(s) to PL(N) of LIB shown in FIG. A specific number that represents the maximum printable driver 1-number of! iI r7
Set FFF (H)j. Next, in step B4, the print start position is determined, and the LIB is re-exercised @ (PL
).

After that, in step B5, it is determined whether the line feed position is smaller than the minimum line feed position, and if the line feed position is smaller than the minimum line feed position, in step B6, after setting the line feed position to the minimum line feed position, The process enters step B7. If the line feed position is greater than the minimum line feed position, the process directly proceeds to step B7.

In step B7, the [number of printable lines@] held in register R3 is set to r-IJL, and then in step B8, 4J is added to the IB pointer, and in step B9
[Number of printable lines 1] is held in register R2 in
is set to "-1". After that, in step 810, it is determined whether the [number of printable lines] held in register R2 has reached rOJ, and if it is not rOJ, step B4
Returning to the process of step B11, if the value has reached "0", the process proceeds to step B11.

In step Bll, the LI8 top address is set in the LIB pointer, and then in step 312, the number of printable lines is set in register R2. After subtracting the minimum line feed position from the line feed position indicated by the LI8 pointer in step 813, r4J is added to the LJB pointer in step 8144. Further step 8
In step 15, the [number of printable lines] held in the register R2 is set to "-1", and then in step 316, it is determined whether the [number of printable lines] has become "0", and [ If the printable line count] is not rOJ, the process returns to step 813 and the same process is repeated.

Then, repeat the steps 813 to 816,
When it is determined in step 816 that the [number of printable lines] has reached rOJ, the process of updating the line feed position from the left turn margin is completed, and the process proceeds to step S5 in FIG.

FIG. 14 shows details of the underline expansion process in step 816 and the underline connection expansion process in step 822 in FIG. 11 above. Lower I! When performing 11 expansion,
First, in step C1, set the horizontal character size as the length of the underline. Then, in step C2, expand the underline on the left side of the character when writing @, and on the right side of the character when writing vertically. Let's do it.

This completes the downward development process.

When performing underline connection expansion, the character spacing is set as the length of the underline in step D1, and then the process of step C2 is executed to complete the underline connection expansion process.

FIG. 15 shows the character layer f; P2! of step 817 in FIG. 11 above. This shows the details of L-embedding. In this character expansion process, first, in step E1, it is determined whether or not it is a line feed code, and if it is not a line feed code, in step E2, it is determined whether or not the ruled line connection bit of LIB is ON. If the ruled line connection bit of LIB is ONL, the horizontal ruled line code is set in the character code in step E3, and then the process proceeds to step E4; if the ruled line connection bit of LIB is not ONL, The process immediately proceeds to step E4.

In this step E4, the character pattern is loaded from RO-115, and then in step E5, the LIB zone number is loaded. Then, in step E6, the character is enlarged based on the line si information such as character size, rotation, italics, outline, etc., and the zone number, and then, in step E7, it is determined whether it is a vertical ruled line code, If it is not a vertical ruled line code, the process ends. Also, if it is a vertical ruled line code,
Proceeding to step E8, a vertical ruled line pattern is developed between the lines, and the process ends. In addition, if it is determined in step E1 that it is a line feed code, in step E9, character development is performed by setting "specific II r7FFF (H)" indicating the maximum number of printable dots at the line feed position of LIB. Finish the process.

FIG. 16 shows the LI shown in step 818 in FIG. 11 above.
B shows details of update processing. In this LIB update process, first, in steps Fl and F2, it is determined from the horizontal character size whether or not it is the final zone for development.If it is the final zone, the underline connection bit in the LIB is turned ON in step F3. Decide whether or not. The above underline connection bit is O
If N, it is further determined in step F4 whether or not after left half-width expansion, and if it is after left half-width expansion, the left half-width of IB is turned ON in step F5, and then the process proceeds to step F6. Proceed to step F6 immediately if it is not after left half-width expansion
Proceed to processing.

In this step F6, a character spacing is added to the line feed position of LIB, and then in step F7, the 118 input digit number is
Play one. Thereafter, in step F8, the LIB zone number is set to "0" and the LIB update process is ended.

If it is determined in step F2 that the zone is not the minimum zone, "24" is added to the line break position of LIB in step F9, and then "+1" is added to the zone number of LIB in step FIO. The LIB update process ends.

In addition, in step F3 above, if it is determined that the underline connection bit of LIB is ONL, step F3 is determined to be ONL.
In step 11, it is determined whether or not the ruled line connection bit of LIB is ON. If it is ONL, the process proceeds to step F6, and if it is not ONL, the process proceeds to step F12.

In this step F12, it is determined whether or not it is a vertical ruled line code, and if it is a vertical ruled line code, LIB is determined in step F13.
After adding the ruled line connection bit to ONL, and then adding the character size to the line feed position of LIB in step F14, the process proceeds to step F8.

If it is determined in step F12 that the code is not a vertical ruled line code, it is determined in step F15 whether an underline connection is necessary, and if an underline connection is necessary, L[8 After setting the underline connection bit to ONI, the process proceeds to step F14.

In addition, if it is determined in step F15 that the underline connection is not necessary, LIB
After adding the character pitch to the line feed position, the digit number of LIB is incremented by 1 in step F7, and the zone number of LIB is set to rOJ in step F8, and the LIB update process is completed.

By using the above-mentioned aspect conversion printing process, line by line,
Even if the document has various character modifications such as left finger margin/line pitch/character spacing wA/character size/rotation/italics/whiteout, etc., or even if the printing start column is different for each line. Even if there is, you can perform vertical/horizontal conversion printing with any specified line in the same way as standard center printing 1j, and in addition, in this case, if the line modification causes the target sentence to be printed to exceed the physically printable range, Even if there is, it is possible to print as many lines as can be printed starting from the first line.

In addition, in the above embodiment, horizontal and horizontal writing of vertical and horizontal conversion is shown in Fig. 17 (C).
