Abstract

PURPOSE:To save sheets of paper and to efficiently perform printing by skipping printing while performing update only with a page number when a page eject code continues in a document. CONSTITUTION:At the time of document printing, the document data divided by the page eject code is printed as one page document while adding a page eject number for each detection of the page eject code in the document. In this case, a page number updating means 1 updates the page number for each detection of the page eject code, and a decision means 2 performs the decision whether or not the page eject code is continued. In such a case, when the continuity of the page eject code is decided, since the printing is temporarily restrained until the continuity is stopped, the only page number is updated and the printing is skipped when the page eject code is continued in the document. Thus, the paper can be saved and the printing can be performed in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document printing device, such as a word processor, equipped with an automatic pagination function.

[Summary of the Invention] This invention provides a document printing device that attaches a page number to document data classified by a page break code and prints it as a one-page document every time a page break code is detected in the document data. , the page number is updated every time a page break code is detected, and it is determined whether the page break codes are consecutive or not, and if they are consecutive, printing is temporarily suppressed until they are no longer consecutive. It is something.

[Prior Art] Conventionally, in word processors equipped with automatic pagination, each time a page break code is detected in a document, a page number is attached to the document data divided by the page break code. I am trying to print it as a document.

Incidentally, it is common practice to insert another document created by means other than a word processor, such as by handwriting or by copying, into a multi-page document created by printing in this manner.

In this case, with conventional word processors, if you want to add a series of consecutive page numbers to the entire document taking into account the material to be inserted, you can insert multiple page break codes consecutively into the document in advance. When printing, blank pages with serial page numbers are printed.

By replacing this blank page with the material that will be inserted later, it is possible to complete a document in which the entire document is numbered consecutively, even if materials created using a means other than a word processor are inserted.

[Problems to be Solved by the Invention] However, printing unnecessary pages for the purpose of serially numbering the entire document wastes paper, and
The drawback was that it took a long time to print.

Therefore, when page break codes are consecutive in a document, it is clear that if only the page number is updated and printing can be skipped, paper will not be wasted and printing can be performed efficiently.

An object of this invention is to enable printing to be skipped by updating only the page number when page break codes are consecutive in one document.

[Means to solve the problem] The means of this invention are as follows.

Page number updating means 1 (see the functional block diagram in Fig. 1,
) updates the page number every time a page break code is detected in the document data. Here, the page number is a series of consecutive numerical values or alphabetic characters.

The determining means 2 determines whether or not the page break codes are consecutive when the page break codes are detected.

When the determining means 2 determines that the page break codes are consecutive, the print control means 3 temporarily suppresses printing until the page break codes are no longer consecutive.

[Action Co. The operation of the means of this invention is as follows.

When printing a document, each time a page break code is detected in the document, the document data classified by the page break code is assigned a page break number and printed as a one-page document.

At this time, the page number updating means 1 updates the page number every time a page break code is detected, and the determining means 2 determines whether or not the page break codes are consecutive.

Here, if it is determined that the page break codes are consecutive, printing is temporarily suppressed until they are no longer consecutive.

Therefore, if there are consecutive page break codes in a document, only the page numbers can be updated and printing can be skipped.

[Example] An example will be described below with reference to FIGS. 2 to 4.

FIG. 2 is a block configuration diagram showing the basic configuration of a word processor.

The CPU II controls various operations of this word processor according to microprograms stored in advance in the ROM 12. When the print program in the ROM 12 is activated, the CPU II reads document data from the document memory 13 and controls the printer control unit 14. The printer 15 outputs a printout via the printer 15.

At this time, the CPU II reads the document data character by character from the document memory 13 and transfers it to the page buffer PB in the printer control unit 14. However, when the page break code is read from the document memory 3, the page An increment process is performed to add "l" to the page number stored in the count register 17. Note that the page number in the page count register 17 is incremented each time a page break code is detected.
This is a series of consecutive numbers that are updated in increments of 1.

Then, the CPU II refers to the print control flag register l7, and if the print control flag is set, it does not transfer the document data into the page buffer PB and temporarily suspends the printing operation, but if the print control flag is set, If not, the document data read from the document memory 13 is transferred to the page buffer PB in the printer control section 14 and printed out from the printer 15. Here, when the CPU II reads document data character by character from the document memory 13,
When consecutive page break codes are detected, a flag "1" indicating printing prohibition is set in the print control flag register 17.

Next, the operation of this embodiment will be explained with reference to FIGS. 3 and 4.

It is now assumed that document data for a plurality of pages has been created and stored in the document memory 13. Here, when a print command is given, the CPU 11 executes a print operation according to the flowchart shown in FIG.

First, the contents of the page count register 16 are cleared and a flag "1" is set in the print control flag register 17 (step Sl).

Then, the read pointer value of the document memory 13 is set to the beginning of the document data to be read (step 2).

When such initialization processing is completed, the process proceeds to the next step S3, where one character is read from the document memory 13 addressed by the read pointer value, and it is checked whether or not it is a page break code (step S4).

Now, the first character data of the first page is read out, but since the first character data is usually not a page break code, proceed to step Sll, clear the print control flag, and then add "1" to the read pointer value. The address is moved to the next character (step 39). Then, it is checked whether the entire document has been read out (step 5IO), but since the first character has just been read out, the process returns to step S3 and the next character is read out from the document memory 13.

In this way, the document data is read out one character at a time, and when all the document data on the first page is read out, a page break code is detected (step S4).

In this case, the process advances to step S5, and after adding "1" to the page count register 16, it is checked whether the print control flag is rQJ (step S6).

Since the print control flag is now cleared, the process advances to step S7, and data for one page up to the next page break position is transferred to the page buffer PB of the printer control unit 14.

In this case, the page number is read from the page count register 16 and written to the page buffer PB. When printing for one page is completed in this manner and the paper is ejected, the process proceeds to the next step S8, where "1" is added to the value of the page count register 16. Then, specify the first character of the next page (step S9), and if printing is not finished, step S3)
Return to

Here, if more page break codes are read out, that is, if the page break codes are consecutive, the page number in the page count register 16 is updated (step S
5) Check the print control flag to see if the page break codes are consecutive (step S6). The print control flag is now "1", and therefore it is detected that the page break codes are consecutive, so the process advances to step S9 and the pointer is updated. That is, if the page break codes are consecutive, only the page number is updated and printing is skipped.

Thereafter, the above-described operations are repeated until the end of the document is detected.

Therefore, when printing document data as shown in FIG. 4, for example, when the first page break code A is detected, the page number is updated from rQJ to "1", and with this page break code A. The classified document data is printed together with the page number "1".

Then, when the next page break code B is detected, the page number is changed to “
At the same time, the document data between page break codes A and 8 is printed together with the page number "2".

However, since page break codes B and C are consecutive in the next page break code, in this case, only the page number is updated and printing is skipped.

After that, when page break code D is detected, the page number becomes "4".
At the same time, the document data between the page break codes C and D is printed together with the page number "4".

Similarly, if the page break codes are not consecutive in the document, the document data will be printed page by page along with the page numbers, but if the page break codes are consecutive, only the page numbers will be updated. Skip printing in between.

Figure 5 shows an example of printing in this case, and the fourth page from the beginning of the printed document has serial page numbers "1", "2", "
4" and "5" are attached. Therefore, if you insert a serial page number "3" into a document created by a method other than a word processor, such as handwriting or copying, you will be able to complete a document with serial page numbers attached to the entire document, including the inserted material. can do.

Note that in the example above, two page break codes are consecutive, but
Three or more may be consecutive.

[Effect of the invention] According to this invention, if there are consecutive page break codes in a document, it is possible to update only the page numbers and skip printing. If you want to add serial page numbers to the entire document, it is economical to simply insert a plurality of consecutive page break codes in the document in advance to prevent unnecessary printing.
