BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing device used in a word processor or the like.

[0002]

2. Description of the Related Art FIG. 1 shows a conventional word processor.
The one shown in 1 is known. This word processor, as shown in (1) of FIG.
Which has one line of document data 51 displayed on the liquid crystal display unit 50, a cursor 52, and a cursor 5
The position data 53 of 2 is displayed with the number of pages, the number of rows, and the number of columns. And if you operate the character keys and line feed keys outside the figure,
The input document data 52 is sequentially displayed on the liquid crystal display unit 50, and the position of the cursor 52 that moves along with the input of the document data 52 is displayed by the position data 53.

Further, in this word processor,
It is also possible to create a frame frame by operating a key, and as illustrated in FIG. 2B, the frame frame data 54 forming the created frame frame, together with the document data 51,
It is stored in the memory 55. Then, when the print mode is set, printing is started based on the data stored in the memory 55, and the document D based on the document data 51 and the frame frame F based on the frame frame data 54 are printed on a predetermined paper surface. .

[0004]

However, as shown in FIG.
As shown in (2), the document data 51 in the memory 55,
With the image data 54 stored in FIG.
As shown in (1), when the cursor 52 is positioned in the first row and the line feed key is operated, as shown in (2) of the figure,
The line feed data 56 is inserted in the first line, and the document data 51
And the image data 54 shifts downward. This allows
Frame frame data that secures an area across multiple lines 5
4 is in a state of extending from the area of page 1 to the area of page 2 in the memory 55.

At this time, since the liquid crystal display unit 50 has only one line of display area, the cursor 52 is moved to display the frame F on the liquid crystal display unit 50 or the position data 53 is used. Even if the number of pages and the number of lines of the frame frame F are confirmed, it cannot be clearly recognized that the frame frame F extends over both pages. Therefore, printing is started in this state, and as a result, the integrated frame F is divided into the first page and the second page and printed.

The present invention has been made in view of the above conventional problems, and provides a printing apparatus in which an integral image of a frame or the like is prevented from being printed across pages. That is the purpose.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. That is, this embodiment is an application of the present invention to a word processor, and the key input unit 1 shown in FIG. Is provided with a plurality of function keys. The word processor is also capable of creating a frame, and keys for creating the frame are also provided in the key input unit 1. The operation information of each of these keys is input to the CPU 2, and the CPU 2 executes the word processor function based on the data and programs stored in the ROM 3 necessary for creating documents and frame frames, and the data stored in the RAM 4. All the controls necessary for implementation are executed and the display drive circuit 5 and the print conversion processing unit 7 are controlled.
The display drive circuit 5 operates according to an instruction from the CPU 2 to drive the liquid crystal display unit 6, the print conversion processing unit 7 converts character data or frame frame data into print data, and the printer 8 uses the print conversion processing unit. It operates based on the print data output from 7 to execute printing.

The RAM 4 has a text memory section 4A.
And display / print character storage unit 4B and line management buffer 4C
Is provided. The text memory unit 4A is shown in FIG.
As shown in (1), the input document data 9 is stored line by line and the frame frame data is also stored.
Here, the document data 9 includes not only character data but also line feed data 13 indicating a line feed of a document and page break data 14 indicating a page break of a document (see FIG. 5 (2)). The text memory unit 4A stores document data 9 corresponding to a maximum of 8 full-width characters in an area for one line.

The liquid crystal display unit 6 displays the document data 9 and the cursor 1 as shown in FIG.
0 and the position data 11 of this cursor 10 are displayed with the number of pages, the number of rows, and the number of columns. In addition, the liquid crystal display unit 6
Is one line of document data 9 consisting of 8 characters,
It has a display area capable of displaying only 6 characters. Then, by moving the cursor 10 downward, as shown in FIG. 3C, the document data 9 for the next 6 characters can be displayed, and by moving the cursor 10 to the right. The remaining 2 characters can be displayed.

The display / print character storage unit 4B reads out one line of data to be displayed on the liquid crystal display unit 6 and one line of data to be printed by the printer 8 from the text memory unit 4A and sequentially stores them. . The display drive circuit 5 drives the liquid crystal display unit 6 based on the data of 6 characters out of the data of 1 line stored in the display / print character storage unit 4B to display the document data 9. . Further, the print conversion processing unit 7 sequentially converts one line of data stored in the display / print character storage unit 4B into print data and sends the print data to the printer 8. The printer 8 sends the print data thus sent. Print text line by line based on.

The paper used for printing the text by the printer 8 has a paper surface capable of printing 12 lines of 8 characters, as shown on the left side of FIG. 3 (1). However, the printer 8 prints the document data 9 only every other line on this paper surface, and therefore, the maximum number of document data 9 that can be printed on the same page is 6 lines. Of course, as shown on the left side of FIG. 2B, the frame F is printed over a plurality of lines.

The line management buffer 4C stores the state of printed text for each line. That is, as described above, since the characters of the text are printed only every other line, when the text is entirely composed of the document data 9, as shown on the right side of FIG. 3A, "Empty line" indicating that printing is not performed on the odd-numbered line is stored, and "number of logical characters / number of text characters" is stored on the line where the character data exists. Here, the number of logical characters is the maximum number of characters in the line, and the number of text characters is the number of characters actually stored in the line.

Therefore, assuming that the text shown on the left side of FIG. 3 (1) is stored in the text memory portion A4, the line management buffer 4C on the right side of FIG. It is stored, "8/8" is stored in the second row, and "8/6" is stored in the even rows of 4, 6, 8, and 12. When only the line feed data 13 exists as in the 10th line, the number of logical characters in the line is “8”, but the number of input characters is “0”, so “8/0” is stored. ing. In addition, FIG. 7 (2)
As shown in, when the page break data 14 exists, all the lines up to and including the 12 lines are “blank lines” or the number of input characters is “0”. Up to, "blank line" and "8/0" are alternately stored.

Further, as shown in FIG. 3B, when the frame frame data 12 is stored in the text, the "line with frame" is stored in the corresponding line of the line management buffer 4C. Therefore, with reference to the line management buffer 4C, it is determined whether or not the frame frame F extends over both pages at the time of printing, depending on whether or not the "line with frame" extends over the page and the next page. obtain.

Next, the operation of this embodiment having the above configuration will be described with reference to the flow chart. That is, the CPU
2 starts control according to the flow shown in FIG. 4 on condition that character data (including line feed data) is input from the key input unit 1 (step SA0), and this character input causes the text memory unit 4A to store data. It is determined whether or not the document (text) has been broken (step SA1). If the result of this determination is that there is no line feed, there is no movement of the document data 9 or frame frame data 12 in the column direction, so the processing in accordance with this flow ends.

However, if it is determined that the line feed processing has been performed, the line management buffer 4C checks the used area of the frame, and it is determined whether the used area of the frame extends across pages (step SA2). . That is, by inputting characters, as shown in FIG. 5 (1), "line with frame"
If the page 1 and the page 2 are used, the used area of the frame extends across the pages, and if printing is performed in this state, the frame F is divided into the page 1 and the page 2. Therefore, in such a case, the page break data 14 is inserted into the first line of the frame frame data 12 (step SA3). By the processing of step SA3, the page break data 14 is inserted between the 9th and 10th lines in FIG. 5 (1), and the page break data 14 is changed to the corresponding position in the text memory unit 4A as shown in FIG. 5 (2). Page data 1
4 is stored. Therefore, this text memory unit 4
By printing the text stored in A, the frame frame F based on the frame frame data 12 is printed with the frame frame F moved to the top of two pages, and the frame frame F is not printed in a divided state.

Further, the CPU 2 starts the control according to the flow shown in FIG. 6 on condition that the character data (including page break data and line feed data) is deleted by operating the delete key on the key input unit 1. (Step SB0), it is determined whether or not the deletion target is page break data (step SB1). If the result of this determination is that the deletion target is not page break data, the deletion of the character data, line feed data, etc. that was the deletion target is permitted (step SB3). However, if the page break data is to be deleted, it is determined whether or not an insertion space for the frame frame data can be secured within the page containing the page break data (step SB2).

That is, when the page break data 14 is deleted in the above-mentioned FIG. 5 (2), the state returns to the state in FIG. 5 (1).
As a result, the "rows with frames" are spread over the first page and the second page, and the area used by the frame frame data extends across the pages. Therefore, in this case, this flow is ended without executing the deletion processing in step SB3, thereby preventing the page break data from being deleted.

However, as shown in FIG. 7A, if there is page break data 14 in the fourth line of the text, as shown in FIG. The 8th line corresponds to the page break data 14. Therefore, if the page break data 14 on the eighth line is deleted,
Space for 5 lines from line 12 to line 12 can be secured. In addition, since there are four "framed lines" on the second page and the frame frame data 12 has a four-line structure, if the page break data 14 is deleted, the first page where the page break data 14 was present is deleted. It is possible to secure an insertion space for the frame frame data 12. Therefore, in this case, SB2
From SB to SB3, the page break data 14 of the first page is deleted. By the processing in step SB3, as shown in FIG. 8, the frame frame data 12 for four lines is moved to the first page in the text memory unit 4A. Therefore, by printing the text stored in the text memory portion 4A, the entire frame frame F based on the frame frame data 12 is printed at the bottom of one page.

Further, the CPU 2 starts control according to the flow shown in FIG. 9 (step SC0) on condition that a character is input from the key input unit 1, and this character input causes the document in the text memory unit 4A to be deleted. It is determined whether or not a line feed will occur (step SC1). If the result of this determination is that there is no line feed, the document data 9 and frame frame data 12
Since there is no movement in the column direction, the character input is accepted (step SC5).

However, in the case of line feed processing, the line management buffer 4C is used to check the used area of the frame frame data, and it is determined whether or not the used area of the frame frame data spans between pages ( Step SC2). If the result of this determination is that the frame frame will not be straddled, the frame frame will not be divided and printed, so character input is accepted (step SC5). However, if it is determined in step SC2 that the frame frame is divided and printed if it straddles, it is next determined whether or not the upper line of the frame frame data is only the line feed data (step SC3). If there is only line feed data, the line feed in the upper line of the frame data is deleted (step SC4), and then character input is accepted (step SC5).

That is, if the character memory unit 4A is in a storage state as shown in FIG. 10 and the character is input with the cursor 10 at the position "A", the line feed at the tail of the line is performed. The data 13a is moved to the next line and line feed processing is performed. However, the upper line of the frame frame data 12 is
Since only the line feed data 13b is included, the character input is accepted after the line feed data 13b is deleted. As a result, all the frame frame data 12 remains on the page, and thus the entire frame frame F based on the frame frame data 12 can be printed on the page.

However, as a result of the discrimination in step SC3,
If the upper line of the frame frame data is not only the line feed data but also character data or other frame frame data, deleting these will delete data not intended by the person performing the key operation. Therefore, in this case, the data in step SC4 is not deleted and the character input is not accepted (step SC6). So in this case,
There is no line feed processing associated with character input, and the text memory section 4A
The frame frame data is maintained in the conventional state in which the frame frame data does not extend between pages.

In this embodiment, step S
In C3, it is determined whether or not the upper line of the frame frame data is only the line feed data. However, it is not limited to the upper line of the frame frame data, and whether the line feed data exists above the frame frame data on the page concerned. Alternatively, the line feed data may be deleted if it exists.
Further, in the embodiment, the liquid crystal display unit 6 having a small area capable of displaying only one line and six characters in full width is shown.
Of course, it can be applied to a large-sized liquid crystal display unit or a word processor having a CRT. Further, in the embodiment, the case where the frame frame data 12 is used as the image data is shown, but the present invention is not limited to this, and it is needless to say that the present invention can be applied to other image data forming an integrated image. is there.

[0027]

As described above, according to the present invention, the image data storage state of the storage unit is controlled so that the image stored in the storage unit is not printed across a plurality of pages of the print medium. I did it. Therefore, by printing on the basis of the image data stored in the storage means, the entire image can be printed on the same page without fail, and the integrated image is divided and printed across the pages. Inconvenience can be prevented.
