Abstract

PURPOSE:To allow documents which retains print style at the time of registration to be output regardless of the change of printing pitch width by automatically updating a registered document registration following the change of printing pitch width. CONSTITUTION:Data is input by an action indication key and when printing is performed, a document format written in the registration format area FOR MAT of RAM3 is copied in a format area FORM for printing. A registered document format stored in the format area for printing FORM is updated and corrected by an integer multiple of a printing pitch which is now being set, that is, a present printing pitch detected by a pitch detector 5 by comparing a registered printing pitch stored in the pitch area PT of RAM3 with the present printing pitch detected by the pitch detector 5. Printing of the document data stored in the text buffer TB of RAM3 is started by pressing a printing start key 31, a single line of printing data is transferred to a line buffer LB, and the data is printed by a printer 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]

2. Description of the Related Art Conventionally, this type of device is configured to store document data input from an input unit in accordance with a preset document format, and to display or print the stored document.

In order to freely select the paper size for printing, a printing format independent of any set document format is set, and printing can be performed in this set printing format.

[Problem to be Solved by the Invention] However, when rereading and printing a document stored in a predetermined document format, the printing pitch width (character pitch width) of the printing medium is unique to each printer. , when printing with a printing device with a different printing pitch width, the print style will be slightly different from the print style at the time of registration, and it will not be possible to output a document that maintains the print style at the time of registration. There was a problem.

In particular, the print column position differs between print lines that perform centering printing using positional information such as tabs and decimal tabs, and print lines that do not, resulting in the print format being significantly different from when it was registered. This requires more editing work, such as reconfiguring the settings, and it is no longer possible to process documents smoothly.

This invention was made in order to solve the above-mentioned problems, and monitors the occurrence of changes in the printing pitch width for registered document formats, and adjusts the registered document formats to follow the changes in printing pitch width. It is an object of the present invention to provide a document processing device capable of outputting an English document that maintains the print style at the time of registration even if the print pitch width is changed by automatically updating.

[Means to solve the problem]

According to the present invention, the document processing apparatus includes a pitch width changing means for inputting an instruction to change a character pitch width specific to a printing means, and a new character pitch width newly inputted from the pitch width changing means and a registration stored in a document information storage means. The document format updating means automatically updates the document format for the document data stored in the document information storage means to an integral multiple of the new character pitch width by comparing the character pitch width with the existing character pitch width.

[Effect]

In this invention, when the pitch width changing means inputs an instruction to change the printing pitch width of the printing means, the document format updating means updates the new printing pitch width newly inputted from the pitch width changing means when printing on the printing means. and a registered print pitch width stored in the document information storage means, and automatically update the document format for the document data stored in the document information storage means to an integral multiple of the new print pitch width;
A printing means prints a registered document in a changed printing area while maintaining the old printing style according to the changed document format.

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

Next, it is determined whether the instruction operation is printing, that is, whether the print key 31 has been pressed 2). If No (during registration or editing), the document format set on the document format screen shown in FIG. 4 is determined. RA (left margin, right margin, tab, decimal tab, etc.)
Write to the registered format area FORMAT of M3 (3).

Next, text document characters are input from the keyboard 7 (4). Then, it is determined whether the text key 30 has been pressed again, that is, whether the end of text editing has been instructed 5), and if No, the text document characters inputted from the keyboard 7 are displayed at the position indicated by the cursor 47 strokes 6). ), return to step (4).

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

On the other hand, if the determination in step (2) is YES (printing), the document format written in the registered format area FORMAT of the RAM 3 is copied to the format area FORM for printing (7).

Then, compare the registered print pitch stored in the pitch area PT of the RAM 3 with the current print pitch detected by the pitch detection unit 5 to determine whether the two print pitches match 8), and if YES, then Proceed to step (10) and later, and if NO, print format area FOR
Currently setting the registered document format stored in M,
That is, the current printing pitch detected by the pitch detection section 5 is updated to an integral multiple (9).

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 (10). If YES, proceed to other key input processing; if No, transfer one line of print data to line buffer LB (print buffer) 11), call print section 4 12), step (
Return to step 10) and continue printing until there is no more print data.

In this way, the document format at the time of document registration is once copied to the printing format area FORM when printing starts, and only when a change in printing pitch occurs, the document format in the printing format area FORM is copied to the detected printing. Since printing is performed by updating in accordance with the pitch, the document format at the time of registration is always saved without being rewritten. Therefore, even if the size of the printing medium, for example, printing paper, is changed, the document data can be printed in the printing style at the time of registration.

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 the above printer heads, there are printers that process font pitch such as Samar head printers, laser beam printers, inkjet printers, etc. If the font pitch of the printing section is different, it is possible to detect the printer type when printing. It goes without saying that if the present invention is applied to correcting the font pitch error, the present invention can also be applied to a document processing device that allows the printer type to be selected.

〔Effect of the invention〕

As explained above, the present invention includes a pitch width changing means for inputting an instruction to change the character pitch width specific to the printing means, and a new character pitch width newly inputted from the pitch width changing means and stored in the document information storage means. The document format update means automatically updates the document format for the document data stored in the document information storage means to an integral multiple of the new character pitch width by comparing the registered character pitch width, so that the printing at the time of registration is Even if you print on a different print medium, the document format that corresponds to the changed print pitch width of the print medium can be created while being automatically updated.
This eliminates the need for many key input operations each time the document format is changed to a print medium, and the user does not have to worry about changing the print medium.
This provides an excellent effect of always outputting a document in the printed format at the time of registration.
