Abstract

PURPOSE:To allow document data which corresponds to a displayed form to be output again regardless of a change of printing media by updating a buffered document format in accordance with current printing pitch width information. CONSTITUTION:Data is input by an action indicator key and if printing is requested, a document format which is written in the format area FORMAT of RAM 3 is copied into a printing format storage RAM 8. Right and left margin position data are read from RAM 3, the left margin position data is subtracted from the right margin position data, and the difference is divided by a printing pitch width. After this, it is determined in which position in a display section 6 the right margin corresponds, and the printing pitch width is multiplied by the quotient. At the same time, the left margin position data is added to the product to update the position of a right margin mark. A value obtained by subtracting the left margin position data from each tabulation position value by the number of tabulation settings in the printing format storage RAM 8, is divided by printing pitch width. Then the printing pitch width is multiplied by the quotient and the left margin position data is added to the product to update each tabulation position. Printing data of a single line is transferred to a line buffer LB and document data is printed by a printing section 4.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to document processing that edits input document data based on created document format information and prints out the edited document data according to a print format. It is related to the device.

[Conventional technology]

Conventionally, in this type of device, document format data, such as information such as margins and tabs set unique to the document, is stored as position data, and when printing, it is accurately compared with the position of the print medium. It was configured so that stored documents could be reproduced and printed.

[Problem to be solved by the invention]

However, in today's document processing devices that permanently store document data, printing paper is reduced.

In many cases, the print pitch is changed for reasons such as enlargement and reprinting is performed, or the document is re-edited for maintenance and then printed.

However, since printing starts without confirming the print pitch width change when registering the document, if printing is performed using a different printing medium, such as a daisy wheel, than when registering the document, the There was a serious problem in that a document with a slightly different print style was output, which significantly degraded the print quality.

This invention was made in order to solve the above problems, and the document format of a registered document is temporarily buffered for printing, and when printing, the buffered printing pitch width information and the current printing pitch width are By updating the buffered document format according to the current print pitch width information by comparing and referencing the It is an object of the present invention to provide a document processing device that can always re-output document data regardless of changes in print media.

[Means to solve the problem]

The document processing device according to the present invention includes a printing format memory for reading out a document format stored in a document information storage means and temporarily storing it for printing, and a pitch for inputting an instruction to change a character pitch width specific to the printing means.

First, an operation instruction key, for example, the text key 30 or the print key 31 is input (1).

Next, check what the instruction action is 2), and if it is registration, input the set document format from the keyboard 7.
Expand to M3 display document format area (3)
.

Next, text document characters are input from the keyboard 7 (4). Then, it is determined whether the text key 3Q has been pressed again, that is, whether the end of text editing has been instructed 5), and if No, the input key is registered in the user memory 6), and the cursor 47 is moved to the specified position. The text document characters inputted from the keyboard 7 are displayed (7), and the process returns to step (4).

On the other hand, if the determination in step (5) is YES, the process moves to other key input processing.

In addition, if the judgment in step (2) is that it is an editing request, the document format (left margin, right margin, tab, decimal tab, etc.) set on the document format screen shown in Figure 4 will be registered in RAM3. Write in format area FORMAT (8), step (4)
).

On the other hand, if the determination in step (2) is a print request, the document format written in the registered format area FORMAT of the RAM 3 is copied to the print format storage RAM 8 shown in FIG. 1 (9).

Next, the right margin position data and the left margin position data are read from the RAM 3, the left margin position data is subtracted from the right margin position data, and the subtracted value is divided by the printing pitch width to determine which digit on the display unit 6. Find out whether the right margin corresponds to , then multiply the quotient N by the printing pitch width (printing state), and then add the left margin position data to the multiplied value to find the right margin in the printing format area. Update the mark position (lO).

Next, it is determined whether or not checking of the tab positions has been completed (11). If YES, proceed to step (13) and later; if NO, the left margin is calculated from each tab position by the number of tabs set in the print format storage RAM 8. Divide the value obtained by subtracting the position data by the above printing pitch width, and further multiply this N for each side by the printing pitch width (in printing state),
Furthermore, add the left margin position data to the multiplied value,
Update each tab position in the print format area12
), return to step (11).

Next, the print start key 31 is pressed to start printing the document data stored in the text buffer TB of the RAM 3, and it is determined whether the printing is finished (13). If YES, move to other key input processing; if No, transfer one line of print data to line buffer LB (print buffer) 14), call print unit 4 and transfer to line buffer LB
15), return to step (13), and continue printing until there is no more print data.

As a result, even if the print pitch width of the print medium is different from that at the time of document registration, it is possible to perform printing in which the display format of the text displayed on the display section 6 matches the print style.

In the above embodiment, a case has been described in which the pitch detection section 5 detects the printing pitch width of a print head such as a daisy wheel set in the printer section 4 and updates the currently set printing pitch. The structure of part 4 is as follows:
In addition to printer devices having printer heads such as those mentioned above, Samar head printers, laser beam printers,
If the font pitch of the printing part of a printer that processes font pitch, such as an inkjet printer, is different, the present invention can be applied to detect the printer type during printing and correct the font pitch error. It goes without saying that the present invention can also be applied to document processing apparatuses that allow selection of printer types.

〔Effect of the invention〕

As explained above, the present invention includes a printing format memory that reads out the document format stored in the document information storage means and temporarily stores it for printing, and inputs an instruction to change the character pitch width specific to the printing means. The pitch width changing means compares the new character pitch width input from the pitch width changing means with the printing pitch width stored in the format memory, and changes the document format stored in the format memory to the new character pitch width. Since a format update means for updating the format by an integral multiple is provided, even if document editing processing such as changing the document format of registered document data is executed and the printing pitch width of the printing means is changed, the current It is possible to obtain a printed output that matches the displayed display format. In addition, the document format when newly registered can be saved without being rewritten.
If there is no change in the print medium, excellent effects such as being able to always print document data in accordance with the document format at the time of registration are achieved.
