When the command to format the document is input by WS, the screen shown in FIG. 10 is displayed on the CRT display unit 1.
It should be noted that this screen is displayed so as to be superimposed on it even if document processing is currently being performed on the screen. Therefore, in order to make the document easier to read, the window shown in the lower right of FIG. 10 can be pointed upward with the cursor K, and the window can be scaled in accordance with the movement of the cursor K. The entire window can be moved by pointing and moving the "format file" portion of the title. Therefore, even if the text screen is displayed, the screen shown in FIG. 10 can be moved or scaled to be displayed in an empty area on the text screen, and the desired format in the window can be easily selected according to the text screen. it can.

Now, with the document of the data n ₁ of the sentence part 33a shown in FIG.
The window of the format file list shown in FIG. 10 is called up and displayed at an arbitrary position on the screen (1), and when the desired format, for example, the format file A is selected by the PD7 and the cursor K, the format shown in FIG. The file A is selected, and its format is copied to the portion of a corresponding to the data n ₁ of the format section 33b shown in FIG. 5 (2). This deletes the form of the document currently being processed. And the formatted output of the document is
Since the processing is performed while formatting the sentence according to the new format in the document, the document being processed is output in the completely new format by the above operation.

[4] Partial Change of Document Format Next, the partial change operation of the document according to the present invention will be described with reference to FIG.

FIG. 13 is a flow chart for explaining a partly changing operation of a document according to the present invention. Note that (1) to (3) indicate each step.

When the document format created by formatting the document in [3] is partially modified, the document file 33 including the format section 33b and the text section 33a is read by the document file table 34 (1), and the CRT is used. In the display unit 1,
Display the document in that format. Then, the parameters relating to the format such as the number of columns, the column set, the line length, and the space between columns are corrected (2), and if they are to be registered, new or re-register them in the document file 33 shown in FIG. Good (3).

Next, the document processing and typesetting processing work according to the present invention will be described with reference to FIG.

FIG. 14 is a flow chart for explaining the procedure of document processing and typesetting processing work according to the present invention. Note that (1)
~ (27) shows each step. Further, the document referred to here is a word including image data. Further, to simplify the explanation, the explanation of the key controller etc. is omitted,
All shall be managed by MPU4.

The MPU4 waits for an input from the keyboard 8 or PD7 (1), and when a key input is made, it is determined whether or not it is a document call command (2). If NO, the control shifts to another control (this invention). If YES, it is determined whether there is no document data on the image memory 11 or the page memory (not shown), that is, the blank state, that is, the initial state (3), YES. If so, proceed to step (5) and thereafter, and if NO, the external magnetic disk device 6
Then, the document data is called on the memory (4). Next, the document data 62 expanded on the VRAM 2 and the edit menu are displayed on the CRT display unit 1 as shown in FIG. 15, for example (5), (6). Then keyboard 8 or PD
Waits for key input from 7 (7), judges whether the key input is an instruction to move the cursor K (8), YES
If so, move cursor K as a position cursor (9),
Return to step (7).

On the other hand, if the judgment in step (8) is NO, the key input is
The PD7 and arrow AR determine whether or not the command is to instruct the "range specification" key in the menu section 61 (10), and YE
If S, the cursor K is set as the range cursor (11), and the process returns to step (7).

On the other hand, if the result of the determination in step (10) is NO, it is determined whether or not the key input in step (7) is an edit command such as line alignment (12). Execute (13), then judge whether or not to make partial correction (14). If YES, the corrected part is displayed on the CRT display unit 1
(15), return to step (7), if NO, wait for the full correction command (16), make full correction when input, display full correction screen on CRT display 1 (1
7), return to step (7).

On the other hand, if the judgment in step (12) is NO, it is judged whether or not the key input in step (7) is a format command (18), and if YES, the input format command is executed (19 ), Return to step (14), if NO, determine whether the key input in step (7) is a layout command (20), and if YES, execute the input layout command (21), NO If so, it is determined whether the key input in step (7) is a print command (2
2) If YES, print processing is executed (23) and the process returns to step (7). If NO, it is determined whether the key input in step (7) is a table setting command (24), and if YES. For example, execute table processing (25) and return to step (7). If NO, determine whether the key input in step (7) is another application selection command (26). If YES, other application. Processing, for example, document updating is performed (27), and the process returns to step (1). If NO, the process returns to step (7).

Securing Memory Next, the relationship between securing the image memory 11 and the printing apparatus 10 according to the present invention will be described with reference to FIGS. 16 (a) and 16 (b).

16 (a) and 16 (b) are image memories according to the present invention.
11A and 11B are views for explaining the relationship between the securing of 11 and the printing device 10, in which W indicates the scan width determined by the paper size, and H indicates the number of scan lines determined by the length of the paper. .

Normally, as shown in FIG. 16 (a), a memory area of the scan width W and the number of scan lines H (1 to H) corresponding to the paper size set in the format setting is secured in the image memory 11, and the DMAC 12 Causes image data 1 to H to be sequentially developed in the direction indicated by the arrow.

On the other hand, in double-sided or double-sided printing, the final image cannot be obtained unless the image is rotated according to the binding margin position or the sheet conveyance direction. Therefore, the scan width W corresponding to the sheet size set in the format setting is used. And a memory area for the number of scanning lines H is secured in the image memory 11, and then, FIG.
As shown in FIG. 5, the DMAC 12 expands in the order of W, W−1, ..., 1 and in the expansion direction opposite to that of FIG.

Development of document data Next, FIGS. 17 (a), (b) and 18 (a), (b)
The document data expansion operation according to the present invention will be described with reference to FIG.

17 (a) and 17 (b) are schematic diagrams for explaining the document data expanding operation according to the present invention. In FIG. 17 (a), the lateral direction of the paper is conveyed perpendicularly to the paper conveyance direction 71. In this case, the transfer state to the image memory 11 is shown, and FIG. 7B shows the transfer state to the image memory 11 when the longitudinal direction of the paper is conveyed perpendicularly to the paper conveyance direction 71.

FIGS. 18 (a) and 18 (b) are schematic diagrams for explaining the memory development coordinates shown in FIGS. 17 (a) and 17 (b). In these figures, Ha and Hb represent the scanning width, and Wa , Wb indicates the scan width.

As can be seen from this figure, the expansion address AD ₁ (xa, yb) of the document data in the image memory 11 when the lateral direction of the paper is conveyed perpendicular to the paper conveyance direction 71 is the longitudinal direction of the paper. When the paper is conveyed perpendicular to the paper direction 71, the scan width Wa is the scan width Wb and the scan width Ha is the scan width.
Since it is changed to Hb, the expanded address AD ₁ (xa, yd) is 90
Mapped to the expanded address AD ₂ (xb, ya) rotated by ゜.

However, xb = Wb−Ya, yb = xa In this way, by controlling the development address with respect to the paper conveyance direction 71, the printed matter can form the same image regardless of the paper conveyance direction 71.

Page Expansion of Document Data Next, the page expansion operation to the image memory 11 according to the present invention will be described with reference to FIGS. 19 (a) and 19 (b).

FIGS. 19 (a) and 19 (b) are schematic views for explaining an example of the page expanding operation according to the present invention, and show the case of expanding the document data of two pages in the page area for one page, for example. .

In the figure (a), 81 and 82 are the document data, and the document data 81 and 82 are stored in the memory area secured from the address O of the image memory 11 with the scan width W ₀ (W ₁ + W ₂ ) and the scan width H _0. In the expanded state, in the same figure (b), 83 is document data, which is secured with scan width W ₀ (W ₂ + W ₁ ) and scan width H ₀ from the point moved from address O to O _1. The document data 83 and the document data 84 are shown expanded in the memory area. The document data 84 is the document data excluding the scan width W ₁ of the document data 81.

As can be seen from these figures, when the expansion of multiple pages with different formats is specified by the format settings, the document data that can be printed on the selected paper size, for example, if the paper size is A3 and the number of documents is " If specified as "2",
As shown in FIG. 19A, the storage area is secured from the address O on the image memory 11 with the scan width W ₀ (W ₁ + W ₂ ) and the number of scan lines H ₀ . At this time, when expanding the page on the left side, that is, when expanding the document data 81,
With the address O as a reference point, the image is clipped with the scan width W ₁ and the number of scan lines H ₀ and expanded in the image memory 11. Then when deploying the right page, it updates the address O ₁ plus address O which has been a criterion for deployment only scan width W ₁ minute, to deploy the document data 82 based on the address O _1.
At this time, in the image memory 11, the scan width W ₀ (W ₁ + W ₂ ) from the address O ₁ on the image memory 11 and the number of scan lines
An area smaller than the area secured by H ₀ by a half scan width is secured. After that, in the same process as described above, that is, when the address O ₁ is used as a reference point, the image is clipped with the scan width W ₁ and the number of scan lines H ₀ and expanded in the image memory 11, it is shown in FIG. Thus, the document data 82 and 81 are expanded. In the case of bag-stitching printing, the scan width W ₁ and the scan width W ₂ may be equal. If the expansion direction is rotated 90 ° to the right, the document data 81, 82 may be expanded as shown in FIG. 17 (b). As a result, for example, when document data having different scan widths are expanded in the image memory 11, the address is updated by the amount designated by the scan width, so that the document data having different formats can be expanded in the image memory 11. Therefore, when the document data is output, the image can be accurately transferred to the printing device 10 based on the format.

Double-sided Printing Control Next, the printing mode for bag binding or double-sided printing will be described with reference to FIGS. 20 (a) and 20 (b).

FIGS. 20 (a) and 20 (b) are schematic views for explaining the printing mode in bag binding or double-sided printing according to the present invention, and the same parts as those in FIG. 7 are designated by the same reference numerals.

The figure (a) shows the printing form at the time of bag printing, the left side shows the odd pages, the right side shows the even pages, the dotted lines show the folding mouths, and t ₁ and t ₂ are headers from the folding mouths. (Column) position, and t ₃ and t ₄ indicate the number (page number) position from the folding edge.

FIG. 2B shows a printing form at the time of double-sided printing, the left side shows the front side, the right side shows the back side, s ₁ and s ₂ show header (post) positions, and s ₃ and s ₄ show Indicates the position of the number (page number).

In case of double-sided printing, the position of the plate 52 on the paper PA (the position of the edge VII),
The header positions t ₁ and t ₂ and the page numbers t ₃ and t ₄ must be taken to be the left and right target positions with respect to the folding edge. Therefore, when formatting is performed, the DMAC 12 causes the document data expansion position in the image memory 11 to be expanded to a predetermined position, that is, the position shown in FIG. 20A between the odd page and the even page. Control.

When performing double-sided printing, the position of the plate surface 52 on the paper PA (in the case of the fore edge VII), the header positions s ₁ and s ₂ , and the page numbers s ₃ and s ₄ are reversed on the front and back sides when odd and even pages are printed. You have to take the position you made. Therefore, when formatting is performed, the DMAC 12 causes the document data expansion position in the image memory 11 to be expanded to a predetermined position, that is, the position shown in FIG. 20 (b) between the odd page and the even page. Control. Note that the top-bottom conditions are omitted for the sake of explanation.

FIG. 21 is a flow chart for explaining the bag binding printing control operation according to the present invention. Note that (1) to (11) indicate each step.

First, it is determined whether the page to be developed is an odd page (1). If YES, the position of the printing plate 52 is taken from the address O on the image memory 11 to the forehead position VII (2). Then, the length (h) of the character string of the header is obtained (3). Next, the header character string is expanded from the address O at a position obtained by subtracting the header character string length (h) and the header position t ₁ length from the scan width W ₁ (4). Next, the length (m) of the character string of the number is calculated (5). Then
The address O is expanded from the scan width W ₁ by subtracting the length (m) of the character string of the page number and the length of the page number s ₁ (6). Next, the document data in the printing plate 52 is developed in the image memory 11 (7) and printed (8).

On the other hand, if the judgment in step (1) is NO, that is,
If it is an even page, the position of the printing plate 52 is taken from the address O on the image memory 11 to the header position t ₂ (9).
Next, the throat position from the address O on the image memory 11
Expand the header character string from the position where II is added (1
0). Next, the character string of the number is expanded from the position obtained by adding the number t _{2 of the number} from the address O on the image memory 11 (11), and the process returns to step (7). Needless to say, double-sided printing can be controlled in the same manner if the judgment in step (1) is made based on whether it is the front side or not.

Next, the relationship between the binding margin position and the development of the document data during double-sided printing will be described with reference to FIGS. 22 (a) and 22 (b).

22 (a) and 22 (b) are schematic diagrams for explaining the relationship between the binding margin position and the development of the document data during double-sided printing according to the present invention. In FIG. 22 (a), PA ₁ is the front surface for double-sided printing. And the case where the binding margin is provided on the left side in the longitudinal direction of the paper.
PA ₂ indicates the back side of another page, and the binding margin position is on the right side in the longitudinal direction of the paper so as to match the binding margin of the front surface PA ₁ .

In FIG. 3B, PA ₃ indicates the front surface in both sides, and is the case where the binding margin is provided on the upper side in the lateral direction of the paper. PA ₄ indicates the back side of another page, and the binding margin position is on the lower side in the lateral direction of the paper so as to match the binding margin of the front surface PA ₃ .

As can be seen from these figures, the document data is stored in the image memory on the front side and the back side, that is, according to the binding margin position set in the format depending on the binding direction during double-sided printing.
When the format shown in (a) of the same figure is set in the case of expanding to 11, the document data is expanded to the image memory 11 in the same direction, and such a format shown in (b) of the figure is set. Is controlled by the DMAC 12 so that the back side of each page is developed in the image memory 11 in the direction opposite to the developing direction of the document data on the front side.

Next, with reference to FIGS. 23 (a) to 23 (d), an explanation will be given of the operation of developing the document data depending on the sheet conveying direction and the binding margin position according to the present invention.

23 (a) to 23 (d) are schematic diagrams for explaining the developing operation of the document data depending on the sheet conveying direction and the binding margin position according to the present invention. In FIG. 23 (a), 91a indicates the front side of the sheet. As shown, it is conveyed in the direction of arrow Q ₁ and an image is formed.
91b indicates the back surface of the paper and corresponds to the front surface 91a. In addition, ● indicates a binding hole. Further, an arrow Q ₂ shows a state where the front surface 91a is fed from the intermediate tray 23a shown in FIG.

In the figure (b), 92a indicates the front side of the sheet, and arrow Q ₁
And the image is formed. Reference numeral 92b indicates the back surface of the sheet and corresponds to the front surface 92a. In addition, ● indicates a binding hole. Further, an arrow Q ₂ shows a state where the front surface 91a is fed from the intermediate tray 23a shown in FIG.

In FIG. 3C, 93a indicates the front surface of the paper, and arrow Q ₁
And the image is formed. 93b shows the back surface of the paper and corresponds to the front surface 93a. In addition, ● indicates a binding hole. Further, an arrow Q ₂ shows a state where the front surface 91a is fed from the intermediate tray 23a shown in FIG.

In the figure (d), 94a indicates the surface of the paper, and arrow Q ₁
And the image is formed. Reference numeral 94b indicates the back surface of the sheet and corresponds to the front surface 94a. In addition, ● indicates a binding hole. Further, an arrow Q ₂ shows a state in which the paper is fed from the front surface 91a to the intermediate tray 23a shown in FIG.

As can be seen from these figures, depending on the binding margin position (binding hole position) and the conveyance direction, when the document data is expanded in the image memory 11 unless the document data is rotated, the optimum double-sided printing mode cannot be obtained. , The DMAC 12 is placed on the back side of the image memory 11 when it is conveyed in the direction shown by the arrow Q ₁ in the binding margin shown in FIGS.
For example, the memory expansion is controlled by the process shown in FIG. 16B so that the document data on the 91b or the back surface 94b is rotated in a predetermined direction and expanded.

Next, the paper feed selection control operation based on the format setting according to the present invention will be described with reference to FIG.

FIG. 24 is a flow chart for explaining an example of a paper feed selection control operation procedure based on the format setting according to the present invention. Note that (1) to (18) indicate each step. The paper is the paper cassettes 24a, 24b or the paper deck 2 shown in FIG.
Paper is fed from 4c, but from the paper feed cassettes 24a and 24b, there is vertical feed in which the longitudinal direction of sheets of the same size matches the transport direction, and lateral feed in which the short direction of sheets of the same size matches the transport direction. There is.

First, the paper size and the orientation of the document made in the formatting step, that is, information about whether the short side is placed at the bottom or the long side is placed at the bottom (1). Next, it is judged whether the size of the paper taken out is a standard size (A3, B4, etc.) (2), if it is NO, the manual paper feed is selected (3), and if it is YES, it is judged whether the manual feed tray is empty. (4) If NO, proceed to step (6) and thereafter, and if YES, paper cassettes 24a, 24b or paper deck 2 loaded other than the manual feed.
It is determined whether or not 4c is present (5), if NO, the process returns to step (3), and if YES, it is determined whether or not a paper cassette compatible with the formatted paper size is installed (6), If YES, it is determined whether the paper stored in the paper deck 24c is the paper size selected in the format setting (7). If YES, the paper deck 24c is selected (8). If NO, the image memory is selected. It is judged whether or not a cassette matching the developing direction of the document data to be developed in 11 is mounted (9). If YES in this determination, it is determined whether the cassette that matches the developing direction is the paper feed cassette 24a, that is, whether it is the upper cassette (10). If YES, the upper cassette is selected (11), and NO is selected. Then select the lower cassette (12).

On the other hand, if NO in step (9), it is determined whether the paper size of the upper cassette matches the formatted paper size (13). If YES, the upper cassette is selected (14). If NO, select the lower cassette (15). By this control, for example, even when the paper cannot be conveyed in the direction that coincides with the developing direction, the image memory 11 of the document data is expanded in the above-described process so that an image can be formed optimally on the paper accommodated in the paper feeding cassette. Since it can be controlled, it forms images without troublesome operations.

On the other hand, if the judgment in step (6) is NO, it is judged whether or not the paper deck 24c is mounted (16), and YES
If so, the paper deck 24c is selected (17), and if NO, the upper cassette is selected (18). The paper selection control has been described by giving an example in which the paper is fed with priority from the paper deck 24c, but the present invention is not limited to this. For example, the throughput can be improved by arbitrarily setting the priority order in which the paper is first fed from the paper deck 24c and the second is fed from the upper cassette 24a.

[Effects of the Invention] As described above, according to the present invention, among a plurality of sheet feeding units, a sheet feeding unit in which a sheet of a desired size is set is set in the sheet feeding unit in the vertical direction. Select whether it is set or set horizontally,
By forming an image in an appropriate direction on the paper fed from the selected paper feeding unit, the operability in image printing can be significantly improved.

In addition, whether the image data of one page to be printed is image data in which the short side is placed down or image data in which the long side is placed down, and the sheet set in the selected sheet feeding means. Since the developing direction of the image data to the storage means capable of storing the image data for one page is controlled based on the direction of
It is possible to form an image in an appropriate direction on the paper fed from the selected paper feeding means without complicating the control.
