Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a document creation device with a line modification front-justification/backward-feeding function.

[Technical Background of the Invention] Recently, document creation devices such as Japanese word processors are required to have a line modification setting function that allows various document formats such as font size to be set on a line-by-line basis. This type of document creation device is useful when, for example, it is desired to selectively enlarge or reduce character strings in arbitrary lines in a document.

[Problems with the background technology] However, the method of setting (specifying) line decoration for each line is
If the number of document lines increases or decreases due to the insertion or deletion of characters or character strings during document proofreading after setting line decorations, there is a problem that the correspondence between document lines and line decorations becomes misaligned.

[Purpose of the Invention] This invention was made in view of the above circumstances, and its purpose is to change the relationship between document lines and line modifications when the number of document lines that make up a document increases or decreases due to the insertion or deletion of characters or character strings. An object of the present invention is to provide a document creation device with a line modification front-justification/backward-feeding function that can adjust correspondence deviations.

[Summary of the Invention] In this invention, the number of document lines constituting a document is increased or decreased by inserting or deleting characters or character strings, and a line modification is set in a row modification information area in association with the document row. If you want to adjust the discrepancy in correspondence with the information, you can instruct to shift the line modification information corresponding to each line following an arbitrary document line to the front, or to move the line modification information corresponding to each line after the arbitrary document line to the rear.

If front-justification is specified, the line modification information in the line modification information area corresponding to each line following the specified document line is front-justified one line at a time from the front, and if backward-justification is specified, In this case, the line modification information corresponding to each line after the designated document line is sequentially advanced one line at a time, and the misalignment between the document line and the line modification information is adjusted.

Further, 41 is a floppy disk controller (FDC), and 42 is a floppy disk drive (FDD).

FIG. 2 shows a memory map of the RAM 20 shown in FIG.

The RAM 20 has a document area 21 that stores (character code strings of) input documents. Here, in the document area 21, for example, 96
00 bytes, that is, 4,800 characters (one character is 2 bytes).The RAM 20 also stores, for example, a 3-byte line modification indicating the document format, for each line of the document stored in the document area 21. It has a row modification area 22 for storing information.This row modification area 22 is allocated to the area starting from address A of the RAM 20.

The RAM 20 also includes a document format area 23 that stores, for example, 3-byte document format information that specifies a document format. This sentence 1! The document format information stored in the I format area 23 includes a 1-line character value that specifies the number m of characters per line (number of characters per line) of the document, as will be described later. Furthermore, RAM20
includes a print image area 24 as a line buffer that stores print image data printed out by the printer 37, and a print format area 25 that stores print format information specifying a print format. The print image area 24 is allocated to an area starting from address T in the RAM 20.

Further, the print format information stored in the print format area 25 includes a left margin value U indicating a print start position (i.e., print left margin) that is a reference for the entire document when performing standard printing.

FIG. 3 schematically shows the correspondence between the document line field secured in the document area 21 of FIG. 2 and the line modification information field secured in the line modification area 22.

As shown in FIG. 3, the document area 21 and the line modification area 2
2, a line with the number of characters m indicated by the number of characters per line information is managed in the middle. Therefore, the maximum number of lines n of a document that can be stored in the document area 21 of the RAM 20 is as follows in this embodiment where 9600 bytes, that is, 4800 characters are allocated to the document area 21.
It becomes 4800/m. In FIG. 3, L and C indicate the 1st line position of the character to be displayed by the cursor, and L indicates the last line position of the document stored in the document area 2. The next document line is 1B+ (L-1)X2m1 of RAM20.
It is stored in an area of 2 m bytes (m characters) starting from the address (B is the starting address of the document area 21). Also in the second row (
The line modification information (corresponding to the document line) is +A+ in RAM20.
(I, -1) It is stored in a 3-byte area starting from address X31 (A is the starting address of the row modification area 22).

FIG. 4 shows the structure of the row modification information stored in the row modification area 22 of FIG.

The line modification information includes a white outline specification flag that specifies the white outline (and shading) of characters, 2-bit rotation/italic information that specifies rotation/italics, and character size (here, 24 x 24 dots full-width characters are the standard). A 4-bit character size value that specifies the print size (magnification), a print stop specification flag that specifies printing to stop midway through printing, a 2-bit character spacing value that specifies the character spacing, and a line pitch (based on standard printing with double-byte characters). It consists of a 4-bit line pitch value that specifies the line feed (line feed), a paper exchange designation flag that specifies paper exchange, and a 7-bit left margin value V that specifies the left margin by the number of digits.

The white designation flag is "1" indicating designated, "0" indicating not designated. Rotation/italic information is "000" without rotation/italic, "001° = rotation 1 (90 degree clock)," 01
0” for rotation 2 (180 degrees counterclockwise), “011” for rotation 3
(270 degrees counterclockwise), “100” indicates italics.

The font size value ranges from "0001" to "1001", from size 1 (magnification, lX1) to size 9 (magnification; approx. 24
24), size Q (magnification: 1/2X) with "1111"
1/2). The printing foreign city designation flag is "l" to indicate that it is designated, and "0" to indicate that it is not designated. The character spacing value is “0”
The character spacing is 0 (θ character bone) to 3 (1×2 characters of the magnification specified by the character size value) in the range of 0” to “11”.

The line pitch value is “1111” and line break B (line break: -10
inch/120), line break O at “oooo” (line feed amount; 0
inch), "0001" is a line feed H (line feed amount; 10 inches/120), "0010" is a line feed K (line feed knee 16 inches/120), "0011" is a line feed E (line feed amount; 20 inches/120), The range of "0100" to "0111" indicates line feed 1 (line feed amount; 30 inches/120) to line feed 4 (line feed amount; 60 inches/120).

The paper exchange designation flag is used to request the operator to exchange paper at the end of printing of the corresponding line in order to set page boundaries, and "1" indicates designation, and "0" indicates no designation.

The left margin value V specifies the print start position of the corresponding line by a relative position (here, number of digits) based on the left margin value U (print start position) determined by print format settings. In this embodiment, the specified range of the left margin value ■ is -9 to 63 digits.

The initial values of the line modification information (this is called standard line modification information) are the outline specification flag - ○ (no specification), rotation/italic information - 000 (no rotation/italic), and font size value - 0.
001 (size 1), print stop designation flag -0 (no specification), character spacing value -01 (character spacing 1), line pitch value -
0010 (line feed K), paper exchange designation flag -0 (no designation), and left margin value v-0 (digit), which are automatically set in the line modification area 22 when the power is turned on.

FIG. 5 shows the structure of the document format information stored in the document format area 28 of FIG.

The document format information includes a line character value specifying the number m of characters per line (number of characters per line) of the document, rotation/italic information, character size value, character amount spacing value, and line pitch value. The bit configuration and specification contents of these rotation/italic information, text size value, character spacing value, and line pitch value are as follows:
This is the same as the row modification information shown in FIG.

Note that the initial values of document format information (this is called standard document format information) are number of characters per line m = 40, rotation/italic information - 0.
00 (no rotation/italics), character size value -0001C size 1), character spacing value -01 (character spacing 1), line pitch value -0010 (line feed K), and is automatically displayed in the document format area 23 when the power is turned on. Set. As is clear, the expiry values of the rotation/italicization information, character size value, character spacing value, and line pitch value are the same as that of the line modification information (standard line modification information).

Next, the operation of one embodiment of the present invention will be described with reference to the above-mentioned figures as well as FIGS. 6 to 19 as appropriate.

(1) Document Input When inputting a Japanese document, the CPU II performs a kana-kanji conversion process by indexing the dictionary area 15 in the ROM 12, for example, for the kanji specified part of a kana character string input from the keyboard 32. After this, a human character code string including the converted Kanji code is stored in the document area 21.

When inputting a document obtained by adding 2, the input characters stored in the document area 21 are developed into a pattern on the display dot memory 35 in the display controller 33 under the control of the CPU II, and are displayed on the display 34.

A low-input document created manually in this manner can be arbitrarily displayed as a character string of up to 40 digits (characters) on the display 34 by operating the cursor keys, and can be used for proofreading, correction, etc. of the document.

(2) Line decoration setting FIG. 6 shows each selection screen (line decoration setting screen) and the order of screen switching operations when setting line decoration.

In this example, if you want to specify document formats such as rotation/italics, character size, character spacing, line break pitch, paper exchange for setting page boundaries, and left margin for the input document on a line-by-line basis, That is, if you want to set a line modification, select and display the character string at the line position you want to modify using the cursor keys, and press the [Function 1] key and other specific keys (here [- ] key) to specify line modification. Note that the c
It is also possible to provide a [row modification] key to replace the above combination key operation.

When the CPU II determines the operation input of the [Function 1] key + [-] key (referred to as the upper [line modification] key for convenience), the CPU II selects a line in the line modification area 22 that corresponds to the line specified for row modification. The modification information is taken out to a line modification information temporary storage area (not shown) in the RAM 20, and the display mode of the display 34 is switched from the document display mode to the line modification display mode.

In the line decoration display mode, as shown in Figure 6, there are items for selecting the square line decoration setting and line decoration leading/backwarding (this will be described later with reference to Figures 9 to 13). A selection screen is displayed, and a cursor is displayed on each of the 11 modification setting items (in this case, the cursor is displayed by inverting the characters). If the [Select/Execute] key is operated in this state, a selection screen for selecting character spacing and line pitch (line break pitch) is displayed. Switching between each item (item switching) on this selection screen is performed by operating the [Next item] key, and selection (designation) of setting candidate values within an item (in this case, character spacing value and line pitch value) is performed in the horizontal direction. This is done by moving the cursor left and right using the (left/right) cursor keys.

Now, when the above selection screen is displayed, the screen state is such that the character spacing can be selected, and the cursor is placed on one of the setting candidate values for the character spacing (character spacing θ to character spacing 3). is displayed. The setting candidate value that is displayed first with the cursor includes the existing settings (default values) of the corresponding item (in this case, character amount interval) in the line modification information temporarily stored in the above-mentioned line modification information temporary storage area. will be adopted. In FIG. 6, a selection screen in which character spacing is specified as an item is shown as a character spacing screen, and a selection screen in which line pitch is specified is shown as a line pitch screen for differentiation. Therefore, in the following explanation, item switching will also be referred to as screen switching.

In this embodiment, in order to set line decoration, in addition to the above-mentioned character spacing/line pitch screen, as shown in Figure 6, there is a character size screen for specifying character size, rotation/italic/outline specification. rotation/italic/outline screen for , print left margin/print suppression screen for specifying left margin value V (print left turn margin)/print stop (print suppression), and paper exchange screen for setting page boundaries. Provided. Switching between the above-mentioned selection screens including the character spacing/line pitch screen is performed by the above-mentioned [Next item] key operation or up/down cursor key operation.

When the screen is switched by these key operations, the CPU II assumes that the setting candidate value at the cursor position immediately before switching has been selected, and changes the line modification temporarily stored in the line modification information temporary storage area in the RAM 20. The settings for the relevant item in the information are updated to the selected contents.

In addition, on the print margin screen, the preset left margin value V is displayed, and if no numerical value is input using the numeric keys, the preset value will be used (within the range of -9 to +63). If the input value is selected, the input value becomes the selection content.

In the line modification display mode, the operator selects and specifies setting candidate values for necessary items by operating the keys described above, and then operates the [Select/Execute] key. CPU
When II determines that the [Select/Execute] key has been input in the line modification display mode, the data in the temporary storage area will be updated in the same way as when the [Next item] key or up/down cursor keys have been operated. Update row qualification information. And C.P.
U11 sets this updated line decoration information in the line decoration information field corresponding to the line specified for the line decoration in the line decoration area 22, and changes the display mode of the display 34 from the line decoration display mode to the document display mode. Return to

(3) Sentence i! F Format Setting FIG. 7 shows each selection screen (format setting screen) and the order of screen switching operations when setting a document format, and FIG. 8 shows a flowchart of document format information setting processing.

In this example, the number of characters per line of the document, as well as the document format such as rotation/italics, font size, and spacing between characters, can be set for the document that is about to be input, the document that is being input, or the document that has already been input. , can be set all at once as described below. In this case, the operator performs a key operation using a combination of the [Function 1] key and another specific key (here, the [!] key) as shown in FIG. Specify F format settings. Note that it is also possible to provide a dedicated [8-type setting] key and perform the above-mentioned combination key operation.

For CPU II, press [Function 1] key + [! ] key (herein referred to as the format setting key for convenience), the document format information set in the document format area 23 in the RAM 20 is transferred to the document format information in the RAM 20 - special note ta
area (not shown), and the display mode of the display 34 is switched from the document display mode to the formatting display mode. In this formatting display mode, as shown in Figure 7, there is a selection screen for specifying single-line character loss (by operating numeric keys), a selection screen for specifying character spacing/line pitch, and a selection screen for specifying character size. A selection screen for specifying rotation and italics and a selection screen for specifying rotation and italics are switched and displayed in the same manner as in the line modification display mode shown in FIG. 6 by operating the 10/down cursor keys.

During this switching display, the preset contents of the corresponding item in the document format information temporarily stored in the temporary storage area are displayed with a cursor (or numerically). Then, by operating the left/right cursor keys (or operating the numeric keys), selection and designation of setting candidate values (or setting value input) is performed.

Now, when formatting work is performed according to the operation order shown in Figure 7 and the [Select/Execute] key is operated, the CPU
I performs processing for setting line modification information in the line modification area 22 and setting document format information in the document format area 23. This setting process will be explained with reference to the flowchart in FIG.

The CPU II first sets the line pointer i indicating the document line to 1 (first line position) (step 5ll), and stores the line modification information of the i-th line, that is, the row modification area 2 prepared in the RAM 20 (step 5ll).
2) extracts the row modification information set in the 3-byte row modification information field starting from address iA+ (i-1)xa1 (step 512). Next, the CPU II determines whether or not the accompanying decoration information has been set according to the row decoration setting operation shown in FIG. 6 (whether or not the row decoration setting is the same) (step S13).

The determination in step S13 is performed according to steps 521 to 32g. In other words, CPULI determines that the white outline designation flag in the retrieved line modification information indicates no white outline designation, the printing stop designation flag indicates no printing stop, the paper exchange designation flag indicates no paper exchange designation, and the left margin value V is θ. (that is, the whiteout designation flag, printing stop designation flag, paper exchange designation flag, and left margin value V are all standard values), which are temporarily stored in the two-legged document format information temporary area. The rotation/italic information, character size value, character spacing value, and line pitch value in the new document format information are currently
If it is the same as that set in the document format area 23 (in M20), it is determined that no line decoration is set.

On the other hand, if even one item does not meet the conditions, C
PUII determines that line modification is set. That is, CPU II
If the line decoration information retrieved in step S12 is standard line decoration information or has been set by formatting, no line decoration setting is specified, otherwise, line decoration setting is specified. Determine. Note that it is also possible to provide a specific bit in the line decoration information that indicates the presence or absence of the line decoration setting, and to make the determination in step S13 (that is, the determination of the presence or absence of the line decoration setting) by referring to the bit. However, in this case, it is necessary to set the above-mentioned specific bit when setting the line decoration information according to the line decoration setting operation shown in FIG.

If the determination in step S13 is No, the CPU II transfers the rotation/italics information, character size value, character spacing value, and line pitch value in the document format information stored in the document format information temporary storage area to the line modification area. 22, in the row modification information field (corresponding position) of the i-th row, and i is the maximum row n.
(Step S15)
. On the other hand, if the determination in step S1B is YES, that is, if row modification is set, the CPU II skips step S14 and performs the determination process in step S15. As a result, the line decoration information set on a line-by-line basis according to the line decoration setting operation shown in FIG. 6 is saved.

If the determination in step S15 is YES, cpuit
The row pointer i is advanced by one (step 816) and the process returns to step S12. On the other hand, if the determination in step 515 is No, the CPU II determines that processing up to the maximum line n has been completed, and sets the document format information stored in the temporary storage area to the document format area 23 in the RAM 20. Then (step S17) the formatting process ends. At this time C
PUII returns the display mode of the display 34 from the formatting display mode to the document display mode.

As mentioned in 11D, in this embodiment, the rotation/italic information, font size value, character spacing value, and line pitch value are added to the line modification information for each line of the document at once by the document formatting operation. Can be set to Further, in this embodiment, line decoration information set on a line-by-line basis according to the line decoration setting operation shown in FIG. 6 is saved. Therefore, no matter when the document formatting operation is performed, there is no risk of affecting the line modification information that has already been set for each line.

(4) Line modification front-justification, backward-shifting Figure 9 shows the order of operations when specifying line-modification front-justification and rearward-shifting. 10(a) and 10(b) show the state of the line modification area 22 before and after line modification front-filling in correspondence with the document area 21, and FIG. 11 shows a flowchart of the line modification front-filling process. Also, FIG. 12(a).

(b) shows the state of the line modification area 22 before and after line modification and forwarding, corresponding to the document area 21, and FIG. 13 shows a flowchart of the line modification and subsequent forwarding processing.

In this embodiment, as described above, line modification information indicating the row modification contents of each line of the document in the document area 21 is stored in the document area 21.
By making settings corresponding to each document line in the line modification area 22 provided independently from 1, line modification settings for each line can be applied to the document in the document area 21 not only during document creation but also during proofreading. This makes it easier to do this without having the same impact. However, if you insert (add) or delete a character or character string after setting the line decoration, the document line and line decoration (
The correspondence with the row modification specification line) may be misaligned.

Therefore, in order to adjust the above-mentioned deviation, a front-justification/backward-adjustment function for line modification is provided.

If the operator needs to move forward or move backward in a row, specify the first line position to be moved forward or backward using the cursor keys, and then press the [Row Modifier] key ([
Function 1] key + [-] key). As a result, the CPU II switches the display mode of the display 34 from the document display mode to the line modification display mode as described above. As a result, an item selection screen for selecting any one of line decoration setting, line decoration front-justification, or line decoration post-adjustment is displayed, and a cursor is displayed on the line decoration setting item.

In this state, use the horizontal cursor keys to specify the ``Front Justify'' or ``Last Feed'' item and click [Select/
By operating the [Execute] key, it is possible to specify front-justification of line decorations or feed-back of line decorations. CPU
In step 11, if the operator's power to press the [Select/Execute] key is determined with "front-justification" specified with the cursor, the line modification front-justification process shown in the flowchart of FIG. 11 is executed, and "backward feed" is With the cursor specified, click [Select/
When the operator's power of the [Execute] key is determined, the line modification post-feeding process shown in the flowchart of FIG. 13 is executed.

(4-1) Line modification When proofreading a front-filling document, for example, delete one line in the 5th document line, as shown in Figure 10 (a), and as a result, the 6th
It is assumed that the following document lines shift forward one line at a time, and as a result, the correspondence between the document lines and the line decorations shifts one line at a time from the fifth line onwards. In this case, the operator specifies the fifth document line with the cursor and specifies line modification front-justification in the above-described operation order. As a result, the CPU II executes the line modification front-filling process described below according to the flowchart of FIG.

First, the CPU II selects the row modification information field (3 bytes) of the next row (in the row modification area 22) based on the line specified by the cursor (cursor row) L (here, L = 5) when specifying front-justification of the row modification. ) start address (here A+ (L-
1) x3) is calculated and set as the starting address a of the row modification information field (step S31). Next, CP
UII sets the number of line modification information to be left-justified as n (maximum line) -
Calculated by the operation of L, the number of remaining row modification information for front-filling is C.
(step 532). Then cptri
It is determined whether t is C=0 (step 53
3).

If c-=0, CPU II a of RAM20
Contents of addresses +4 to a+6 (M(a+4) to M(a+6)
) That is, the row modification information of the (i+1)th row (the initial value of i is L) is converted to the contents of addresses a+1 to a+3 of the RAM 20 (M (a
+1) to M (a+3)), that is, the process of making the first line row modification information (step 534) is performed. Next, CPUII
advances a by 3 addresses to find the start address of the line modification information field of the next line (step 535), decrements C by 1 (step 530), and returns to step S33. Then, until the processing in steps 533 to 836 reaches c-0,
That is, the process of shifting the line modification information from the (L+1)th line to the nth line (maximum line) forward one line at a time is repeated until all of the processes are completed. As a result, in this example of L-5, FIG.
), the line modification information in the 6th line is transferred to the 5th line, and the 7th line
The row modification information of the row is shifted to the 6th row, and so on, and the row modification information after the 6th row is sequentially shifted forward one row at a time, and finally the row modification information of the 0th row is moved to the (n-1)th row. This adjusts the misalignment between document lines and line decorations.

When c-0 is obtained through the above processing, the CPU II outputs the first byte I (
1) ~ 3rd byte I (3) in RAM 20 a -
Processing to set the contents of address a+2 (step 537) is performed. As a result, the contents of the row modification information field of the 0th row (maximum row) in the row modification area 22 are initialized.

(4-2) When proofreading a sent document after line modification, for example, add one line after the fourth line of the document as shown in Figure 12(a), and as a result, the text from the fifth line onwards It is assumed that the lines are shifted backward one line at a time, and as a result, the correspondence between the document line and the line modification is shifted one line at a time from the fifth line onwards. In this case, the operator specifies the fifth document line with the cursor and specifies feed after line modification in the above-described order of operations. As a result, the CPU II executes the line modification post-feeding process described below according to the flowchart of FIG.

First, the CPU II calculates the start address of the line modification information field of the (n-1)th row, and sets it as the row modification information field start address a (step 541). Next, the CPUIL calculates the number of row modification information to be postponed by calculating n-L, and sets it as the number C of remaining row modification information to be postponed (step 542). Next, CPU II c
It is determined whether or not it is -0 (step 543).

If it is not c-Q, CPU II has RAM 20 (
7) The contents of address a - a + 2, that is, the row modification information of the first row (the initial value of i is n-1), are transferred to a + 3 to a of the RAM 20.
A process (step 544) is performed to set the contents of address +5, that is, the row modification information of the i+1st row. Next, CPU II sets a to 3
Go back and find the start address of the line modification information field of the previous line (step 545), and reduce C by one (
Step S4B) Return to step S43. Then, the processing of steps S43 to S54ft is repeated until C-0 is reached, that is, until the processing of shifting the line modification information from the (n-1)th line to the second line forward one line at a time is completed 1'. As a result, in this example of L-5, the row modification information of the (n-1)th row is transferred to the 0th row, as shown in FIG.
2) The line modification information of the row is shifted to the (n-1)th row, and so on, one by one, and finally the row modification information of the 5th row is shifted to the 6th row. The misalignment between document lines and line decorations is adjusted.

However, in the above process, for example, if paper exchange is specified in the 5th line (th column) as shown in FIG. The line modification information is copied to the 6th line. For this reason,
Paper exchange was originally required, and although the addition of one line makes it possible to correctly exchange paper for the document line that became the 6th line, there is an inconvenience that the additional line that became the 5th line is also specified for paper exchange. occurs. Therefore, in this embodiment, in order to prevent the above-mentioned inconvenience, when c=0, the following processing is performed.

First, the CPU II advances a by 3 addresses and moves a to the next row (L-5
) to the start address of the row modification information field (step 547). And CPU II is RAM20 a+
The paper exchange designation flag in the contents of address 2, that is, the paper exchange designation flag in the line modification information of the second line (L-5) is reset (step 548). As a result, a new fifth
There is no longer a possibility that the additional line that has become a line will be designated for paper replacement.

The above 1 can be applied not only to the addition or deletion of individual lines, but also to cases where the number of lines in a document changes due to the addition or deletion of characters or character strings.

(5) Line copy Figure 14 shows a flowchart of the line copy process. By executing the flowchart, as described below, any document line can be copied to any line position, and the document line can be copied. It is possible to realize a function that automatically adjusts discrepancies in the correspondence between document lines and line modifications when copying ('F).

When the operator needs to copy a line, the operator specifies the line position of the desired document line to be copied by operating the cursor keys, and then performs a key operation (for example, by a combination of the [Function 2] key and the [$] key). For convenience, this is referred to as a row copy cokey operation to specify the row copy.

When the CPU II determines that the [Line Copy] key has been input, the CPU II sets the line position designated by the cursor to Ls indicating the line position from which the line is to be copied (step 551), and, for example, displays the entire specified document line in reverse video and displays " Copy line Where?
” is displayed in the guide display area of the display 34 (step 552). In this state, the operator operates the up/down cursor keys to move the cursor to the row copy destination line position, and operates the [Select/Execute] key.

(:, P U It scrolls the screen in conjunction with the up/down cursor key operations, and when it determines the human effort required to press the [Select/Execute] key (steps S53 to 555), it scrolls the screen to the document line currently designated by the cursor. The line position of is set in LD indicating the line position of the line copy destination (step 856).

Next, the CPU II searches the document area 21 and
Find the last line Lε of the input document stored in (step 557). The details of this step S57 are as follows.

First, the CPU II sets the line pointer i indicating the line position on the document area 21 to 1 (step S71).

Next, the CPU II determines the storage address on the RAM 20 of the first digit of the i-th line based on the number of characters per line m in the formatting information set in the document format area 23. Find (storage start address) J (step 572) and read 2 bytes (character code) starting from address J in RAM 20 (step 573)
. The CPU II stores the 2 bytes read from the RAM 20 (i.e. the character code of the first digit of the i-th line) in the system space (
system space code) (step 574). This system space code is
Unlike regular space codes that indicate white space, they do not constitute a document. That is, in step S74, the CPU II determines whether the i-th line does not constitute a document line.

If the determination in step S74 is No, that is, if the i-th line constitutes a document line, the CPU II determines that the number of characters in one line is m.
It is determined whether i matches the maximum line n of the document area 21 in the case of (step 575). If i does not match n, the CPU II advances the row pointer i by one (step S7[i), and returns to the process of step S72.

On the other hand, if i matches n, since the i-th line is the last line of the document, the CPUIL sets the value (=n) of the line pointer i at that time as LE (step 5
77).

On the other hand, if the determination in step S74 is YES, that is, the i-th
If the line does not constitute a document line, the previous line (i-1) is the last line of the document, so the CPU II
sets the value obtained by subtracting 1 from the value of row pointer i as LE (step 878).

After searching for the last line of the document according to steps S71 to S78, the CPU II proceeds to step 358 and determines whether LE matches n (step 858).

If the determination in step S58 is YES, the CPU II determines that the document area 21 is full, that is, it is impossible to copy lines, and displays the "number of lines exceeded" message (S9, knob 55).
9) to issue a row copy cancellation request, and enter a state waiting for human input from the [cancel] key (step 560).

On the other hand, if the determination in step S58 is No, the CPU II
The process proceeds to step 581, where it is determined whether LD is less than or equal to LE.

If the determination in step S61 is No, that is, if the line copy destination is beyond the last line of the document, the CPU II
1, line feed codes are supplemented by (LD-L4-1) phalanges from the (Ls+1)th line (step 562). and C
The PUII copies the Ls-th document line to the LD-th line in the document area 21 (step 563), and also copies the line-modification information of the LS-th line to the line in the line-modification area 22 (step 564). Ends row copy processing.

On the other hand, if the determination in step SBI is YES, cptr
tt shifts the document lines from the LD line to the Lε line one line backward in the document area 21 (step 565), and
In the row modification area 22, the row modification information from the LD row to the L.epsilon. row is shifted one row later (step 38B), and it is determined whether LD after L is less than or equal to t, s (step 587).

If the determination in step S87 is No, that is, if the line copy destination is before the line copy source, the CPU II executes step SB3. Execute S64 and end the process.

On the other hand, if the determination in step SB7 is YES, step S65. In the movement process of S6[1, the document line and line modification information of the Lsth line are also shifted one line later (that is, to the (Ls+1)th line), so cptrtt moves the document of the (Ls+1)th line in the document area 21. The row is copied to the LD row (step 868), and the row modification information of the (Ls+1)th row is copied to the LD row in the row modification area 22 (step 569), thereby ending the row copy process.

Note that when executing step S65, 5613,
RA document line and line modification information of line s (line copy source)
By temporarily storing the information in a predetermined area in M20 and using this temporary storage information as the copy source information when copying to the LD row, steps SG7 to SG5 (i9 become unnecessary, t, . . . A common copying process (steps S fi3 and S84) can be applied regardless of the size of Ls.

(6) Centering, right alignment Figures 15 (a) to (d) are diagrams for explaining centering and right alignment that take into account the line modification of character strings after any character column in any document line, and Figure 16 shows centering, It is a flowchart of right alignment processing.

For example, when an operator wants to center or right-justify cde of the character string abcde in the first document line shown in FIG. Combine,
For centering, the key operation is the combination of the [Function 1] key and the [“] key (for convenience, this is called the [Centering] key operation), and for right alignment, the key operation is the combination of the [Function 1] key and the [“] key. A key operation based on the combination of (this will be referred to as a [right alignment] key operation for convenience) is performed.As a result, CI) ULI performs the centering and right alignment j1 processing described below according to the flowchart of FIG.

The CPU II first uses the character size value, character spacing value, and number of characters per line (n) indicated by the document format information set in the document format area 23 to determine the number of document lines (on the print image) defined in the format settings. Length, i.e. 1λtei Yukinaga J! (see FIG. 15(b)) is calculated (step S81).

In other words, cptrtt is determined in the format settings by multiplying the character pitch of the full-width characters (standard characters) indicated by (1 + character amount interval in the document format information) x 24 (dots) by the magnification indicated by the character size in the document format information. Find the character pitch of the characters with the given magnification, and then multiply the number of characters per line by 7F to the same character pitch to find the value (in units of Dr.I.).

Next, the CPU II calculates the length of the leading character string on the print image, taking into account the line modification of the character string (in this case, ab) that precedes the centering and right-aligned anti-cannon character string in the i-th document line specified by the cursor. long) 11 (Figure 15(b)
(see step 582). This I! ! (Unit: dot) is the character pitch of the full-width characters (standard characters) indicated by (character amount interval in the line modification information of the 10th i line) x 24 (dot) and the character size indicated in the line modification information. It is obtained by multiplying the magnification by the number of characters in the preceding character string indicated by (the character digit indicated by the cursor - 1).

Next, the CPU II determines whether or not , is greater than or equal to , (step 583), and if YES, it is assumed that centering and right alignment are impossible, and the process ends. On the other hand, if the determination in step S83 is No,
CPU II calculates the difference 12 between l and 11. Step 5
84) Search and center the i-th document line in the L document area 21.

Right-justified target character string (the first character after the character digit indicated by the cursor)
The number of characters f in the row character string is determined (step 585). Then, CPU II uses this f to calculate the length of the target character string on the print image, taking into account the line modification of the centering and right-aligned target character string (here, cde).
dot) is calculated (step 886).

Next, cptrtt determines whether or not P is 12 or more (step 587), and if YES, it is assumed that centering and right alignment are impossible, and the process ends. On the other hand, if the determination in step S87 is NO, the CPU 11 calculates the difference F between 1lI2 and l'p,
(see FIG. 15(b)) is calculated (step 38g),
It is determined whether right alignment is specified after L (step 589). If right alignment is specified, the CPU II sets the number of dots indicated by NoE to Nos as the number of blank dots to be compensated for by right alignment.Step 59
0), if centering is specified, 1/2 of the number of dots indicated by 1B should be set to 17s as the number of blank dots to be compensated for by centering.Step 59
1), both proceed to step S92.

In step S92, the number of blank dots J! Processing is performed to convert s into the number of blank characters (number of spaces) on the print image in consideration of line modification, that is, the number of blank characters (number of spaces) N to be inserted before the character string to be centered and right-justified. Next, (the character digit indicated by the cursor - 1) and N
and the number of target characters f is calculated (step 593).
, R is less than the number m of characters per line determined by formatting (step 594).

If the determination in step S94 is YES, the CPU II
In the first document line of the document area 21, as shown in FIG.
As shown in the figure, N spaces (space code) (for N characters) are inserted from the digit position indicated by the cursor (that is, the beginning of the target character string) (step 595). As a result, the first document line in the document area 21 correctly reflects the centering and right alignment on the print image in consideration of the line decoration.

On the other hand, if the determination in step S94 is NO, the number of characters in the first document line will be greater than or equal to the number of characters in one line if N spaces are inserted. A process of moving the character string to the right end is performed (step 59B). As a result, the first document line in the document area 21 is centered on the print image in consideration of line decoration.

The right alignment is reflected as much as possible without causing the disappearance of characters or character strings.

(7) Print start position setting when printing 'As Figure 17 is a diagram explaining the print start position (left margin) set for each line and document, and Figure 18 is marked 1
FIG. 19, which is a diagram showing the relationship between the configuration of one image area 24 and the writing start position, is a flowchart mainly of the process of determining the print start position (the writing start position in the print image area 24) during printing.

The operator marks the input document (or edited document) with IJI.
In case of I L, press the [Print] key (
Actually, operate the [Function 1] key + [≧] key). This causes the CPU II to display a print menu. In this state, the operator can specify the left margin value U, vertical/horizontal printing, Japanese/English printing, etc. In specifying this left margin value U, as shown in FIG. 17, a scale marked on a scale 51 provided at the paper feed section (paper insertion slot) of the printing mechanism is used as a guide. Here, a scale is provided from θ to 56 in units of 27 dots (full-width character size; 24-dot cross-character spacing: 3 dots), which is a standard character pitch. When the [Select/Execute] key is operated after this, the specified print format is set in the print format area 25, and after that,
A printing operation is performed according to this printing format. In this printing operation, the line modification information set in the line modification area 22 is also referred to.

Now, assume that the first document line is to be printed.

In this case, the CPU II determines the write start address P in the print image area 24 corresponding to the left margin (print start position) on the print format based on the left margin value U in the print format information set in the print image area 24. (address on RAM 20) is calculated (step 5LOL). Here, the print image area 24 is used like a two-dimensional memory of 24 dots (ie, 3 bytes), which is the number of dots constituting the print head, x one line of print head drive operation range (unit dot). Therefore, the 24th dot of the jth dot row in the print head drive operation range for one line (one zone printing area)
The dot (3 bytes) is 3j in the print image area 24.
~3j+2 address (relative address within print image area 24),
That is, address T+3j-T+3j+2 of RAM20 (T is R
3 bytes of the starting address of the print image area 24 in A M 20 are allocated.

Therefore, the write start address P on the above-mentioned print format is determined by the calculation of T+(27xux3).

After completing step S101, the CPU II reads the line modification information of the i-th line, which is the line to be printed, from the line modification area 22 (step 5102). And CPUII is the i-th
In the case of centering and right alignment as described above, the horizontal dot length occupied by the digit (character digit) indicated by the left margin value V in the line decoration information of the line is determined by taking into account the line decoration (character size, character spacing, etc.) Write the print image of the i-th document line by multiplying this dot length by 3 (because one dot row requires 3 bytes in the print image area 24) and adding P to the result. A start address S is calculated (step 5103).

After determining the write start address S, the CPU II determines whether S is equal to or greater than the first address of the print image area 24 (step 5104).

Even if the determination in step S104 is No, the CPU II does not count the time (since it is impossible to write a print image from the address indicated by S), proceeds to step S8106, and selects T as S, and proceeds to step S104. Judgment of 104 or Y
If it is ES, the process directly advances to step 8106.

In step S IOG, the CPU 11 writes a print image in consideration of the line decoration of the character string in the i-th line (i.e., according to the line decoration specification) into the area of the print image area 24 (on the RAM 20) starting from the write start address S. expansion/
Develop a one-zoon line pattern that has been reduced, rotated/italicized, or outlined. Next, in step 51, the CPU II executes printing for one zone (one print line) using the print image developed in the print image area 24.
07), after L is completed, it is determined whether or not printing for the required number of zones has been completed for the it line (step 510).
8). Then, the printing of the i-th line is completed by printing for the number of zones determined by the character size, etc. As a result, on the paper 52 shown in FIG.
Shifted to the left or right by the number of digits (number of character digits) indicated by the left margin value V tested in the line modification of the i-th line from the printing left margin (standard printing start position) determined by the format settings. Printed from position. In addition, the i-th pitch is
It goes without saying that the font size and spacing specified in the line decoration are reflected.

In this embodiment, if printing stop is specified by the print stop designation flag in the line modification information of the i-th line, the printing operation is temporarily stopped and the print menu is displayed. This allows the operator to switch between English/Japanese fonts and exchange color ribbons for printing. Also the i
If paper replacement is specified by the paper replacement designation flag in the line modification information for a row, a message prompting paper replacement is displayed when printing of the i-th line is completed. In this state, when the paper is replaced and the [Select/Execute] key is operated, a print menu is displayed. In this state, the operator can specify switching between English/Japanese fonts, vertical/printing format, etc. When the [Select/Execute] key is operated after this designation, printing is performed in the designated print format with the i+1st row as the first row.
