Abstract

PURPOSE:To automatically set a blank line into a document without interrupting the continuity of the document by outputting the document data on the next line as the document data on the next page after the coincidence is confirmed the output line number set at output of the document data on the next line and the output line number equivalent to one page excluding the set blank line. CONSTITUTION:A document processor consists of a keyboard 1, a CPU 2, a display part 3, a print part 4, a ROM 5a, a RAM 5b, a line counter 6, a register 7 and a print buffer 8. A command is inputted to point the number of blank lines in one page, and the output line number equivalent to one page excluding the blank lines is set based on the input command. Then the set output line number is compared with the output line number set at input of the document data on the next line. When the coincidence is confirmed between both output line numbers, the document data on the next line is outputted as the document data on the next page. As a result, a blank part can be automatically set by editing without impairing the contents of a document.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document processing device, for example, a document processing device such as an electronic typewriter.

[Prior art and its problems] Conventionally, in this type of device, when printing a document,
A page break was performed by inserting a page break command. When printing is done in this way, for example,
The printing results were as shown in the printing results 100 to 102 shown in the figure. In the print result 100, two blank lines are set only in the line spacing at the position X, and the number of blank lines is uneven. Also, in the print result 101, a space is not set at position x2 before the first character in the first line, making it difficult to read whether it is a continuation from the previous page.
Now, it seems troublesome whether there should actually be a blank line in each line of Xs and X4.

As described above, the conventional example described above has the drawback that the page break command moves as the document is edited, and the size of the blank space changes. Another disadvantage is that inserting a page break command breaks the continuity of documents.

The present invention has been made in view of the above-mentioned drawbacks of the conventional example, and its purpose is to provide a document processing device that can automatically set blank areas without destroying the contents of a document by editing. be.

[Means for Solving the Problems] In order to solve the above-mentioned problems and achieve the purpose, a document processing device according to the present invention outputs document data line by line. an input means for inputting a command instructing the number of blank lines; a setting means for setting the number of output lines for one page excluding blank lines based on the command input by the input means; and outputting the next line of document data. a comparison means for comparing the number of output lines when the output line is set with the number of output lines set by the setting means; and when the comparison means confirms that the number of output lines matches, the document data of the next line is set as the document data of the next page. and output means for outputting the output.

[Operation] According to this configuration, the input means inputs a command instructing the number of blank lines in one page, and the setting means outputs one page's worth of output lines excluding blank lines based on the command input by the input means. The comparison means compares the number of output lines when outputting the next line of document data with the number of output lines set by the setting means, and the output means uses the comparison means to confirm that the output line numbers match. The next line of document data is output as the next page of document data.

[Embodiments] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing the configuration of a document processing apparatus according to this embodiment. In the figure, reference numeral 1 indicates a keyboard provided with various keys for inputting/outputting and editing documents, and reference numeral 2 indicates a CPU that controls the operation of the entire apparatus according to various programs in the ROM 5a. Reference numeral 3 indicates a display unit that forms a display screen when editing a document, and reference numeral 4 indicates a printing unit that prints the document in response to instructions from the keyboard 1.

5a indicates a ROM that stores a control program, an error processing program, a program for operating according to the flowchart in FIG. 3, etc., and 5b is used as a work area for various programs and a temporary save area during error processing. RAM is shown. Further, 6 indicates a line counter that counts the lines to be printed in the document data, and 7
indicates a register that stores the number of blank lines set by a specific command. Reference numeral 8 indicates a print buffer that stores document data to be printed.

As for the operation of the above configuration, the CPU 2 displays the document stored in the RAM 5b on the display section 3 in accordance with each instruction from the keyboard 1, and edit processing is performed. Also, CPU2
transfers the document data stored in the RAM 5b to the print buffer 8.
The printing unit 4 executes printing based on the document data stored in the print buffer 8.

Next, a method of storing document data will be explained.

FIG. 2 shows an example of document data stored in the RAM 5b of this embodiment. As shown in the figure, the document data usually includes the top margin, page end, left margin, right margin, and number of tabs.

It consists of data such as tab information and character data (including spaces, etc.) in the actual document. In this example,
[7] in the character data indicates a specific command that indicates the number of blank lines, and "7" indicates the size of the blank space, that is, the number of blank lines. In this way, in this embodiment, the character data is inserted at the beginning of the line. This insertion method will be described later.

Next, the operation of this embodiment will be explained.

FIG. 3 is a flowchart showing the document processing operation of this embodiment.

First, the keyboard 1 is used to create a document or read document data from the RAM 5b that stores the document to edit the document. At this time, the user can specify a new line page for each related document (step Sl, step S
2). To do this, use the keyboard 1 to write a specific command such as [7
].

Thereafter, the document data is stored in the RAM 5b with the specific command added (step S3), and the next instruction from the keyboard 1 is awaited (step S4). After this,
If there is a print processing instruction (step S4), the register 7
The contents of the line counter 6 are cleared to "0" (step S5), and one line of document data is extracted from the RAM 5b and stored in the print buffer 8 (step S6).

Then, the contents of the line counter 6 are incremented by one (step S7), and then it is checked whether a specific command exists in the extracted one line of document data (step S8). As a result, when the existence of the specific command is confirmed, the number of blank lines indicated by the specific command is set in the register 7 (step S9).

In this way, the process proceeds to step SIO, where one line of printing is performed, and then it is determined whether line feed printing or page feed is to be performed (step 511). In this judgment,
If any of the three conditions (■ to ■) listed below apply, a page break is performed, and if the conditions do not apply, a line feed is performed. As a parameter, the number of lines on one page is P
, β is the number of blank lines stored in the register 7 or the number of lines stored in the one-line counter 6, and ρ° is the number of lines after a line break.

The conditions are: ■β≦P−b (number of printable lines) ρ°, ■P ρ°
, and ■ The document data has a normal page break command. So, for example, P=38. When b = 7 (P - b = 31), the number of lines is 2 from the 1st line to the 29th line, except when a page break command (■ condition) exists in the document. Printing is performed with line feeds sequentially (step S6 to step 512), and when the number of lines ρ before line feed reaches the 31st line, the number of printable lines (P-b=3)
1), and the number of lines β° after the line break is the 32nd line, so the condition (2) is satisfied (β≦p−b<ρ゛).

Therefore, a page break is performed to print the next line as the first line of the next page (step 513). If a page break is performed, it is determined in the next process whether or not the pre-printing process has ended (step 514), and until the end,
The process returns to step S5, and the printing process for a new page is started again. Further, when the end of the process is confirmed in step S14, the process returns to step S4, and the process is executed according to the key input from the user.

FIG. 4 shows the printing results of this example. The range indicated by E in the figure indicates the blank line portion set according to the flowchart of FIG. 3 described above.

Further, in this embodiment, a blank line can be set within a page of document data in a text area in RAMSb by display processing as well as by printing processing. In this case, steps 85 to S14 in the printing process correspond to steps 815 to S24 in the display process, and the printing process is replaced with the display process, although the explanation is omitted because it is similar to the printing process described above. Only. When this processing shifts to display processing, it is determined in step S4 that the instruction from the keyboard 1 is for display.

As described above, according to this embodiment, blank lines in a document can be automatically set without breaking the continuity of the document.

[Effects of the Invention] As described above, according to the present invention, blank lines in a document can be automatically set without breaking the continuity of the document.
