Abstract

PURPOSE:To reduce the lowering in operability accompanied by the alteration of a character size during the formation of a document, by preliminarily displaying a character with an underline and an open character etc. corresponding to the kind of a property indicated and indicating the character size at every property at the time of printing to perform printing. CONSTITUTION:When an input data is a data indicating a property, an editing processing part 11 controls a display control part 14 to detect the character at a position displaying a cursor, that is, a character of which the property is indicated and discriminates the position of character data concerned from the character data stored in a character data storing area 12 not only to insert a property code immediately before said character data but also to turn the bit of the inserted code corresponding to said property ON. Then, the character at the cursor position is again displayed in the form matched with the property indicated to finish processing. Next, a printing condition indicating picture is displayed and, for example, when the conditions of '12P' and 'UNDERLINE' are indicated, an ordinary character is printed at 12 points and only a character with an underline is printed at 10.5 points.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a document creation device equipped with a printer capable of changing dot pitch.

In general, document creation devices such as word processors have a length of 24
Dot or 32-dot dot printers are often used, and in such dot printers, the character size is fixed depending on the dot pitch.

When printing by changing the font size with such a printer, not only does it require significant changes to the control logic in the line direction, but it also requires an algorithm built into the printer to enlarge or reduce the dot font. By changing the text font, the text size was essentially changed.

This required a large amount of memory to store the font conversion algorithm and conversion logic, and since the enlargement/reduction algorithms could not be shared between different fonts, they had to be created for each font. .

However, in recent years, printers such as the Infusiera 1 printer and laser beam printer that can change the dot pitch, and the F!
61! A type of thermal transfer printer has also appeared that allows printing by switching between different times.

However, even when such a printer is used, since the pitch of the driver 1 of the display device 2 remains fixed, it is not possible to display the font size output by the printer 1 as is; for example, as shown in The control character S shown in a) is added to express the change in font size, and the control character S shown in the same figure (b) is
) so that the printing results shown in the figure can be obtained.

This control character occupies one character area on one display,
Because it is removed and printed when printing.

The disadvantage is that the displayed image and the printed image are different, and the operability of data input is greatly reduced.

Purpose This invention has been made in view of the above points, and is aimed at reducing operability due to partial change of font size of one created document in a document creation device equipped with a printer capable of changing dot pitch. The purpose is to prevent

M-Consideration In order to achieve the above object, the present invention provides an attribute indicating means for indicating an attribute in a character string or character unit of a created document in a document creation device equipped with a printer capable of changing the dot pitch; The apparatus is provided with a font size specifying means for specifying a font size for each attribute specified by the instruction means, and a print control means for causing the printer to print the created document in the font size specified for each attribute. .

Hereinafter, a detailed explanation will be given based on one embodiment of the present invention.

FIG. 1 is an external perspective view showing an example of a document creation device embodying the present invention.

This document creation device uses characters (9 hiragana and 9 serikana).

a keyboard 1 as an input device for inputting information (including alphabets, symbols, etc.) and control information necessary for document creation, editing, printing, etc., and a display device having a multi-line display area for displaying created documents, etc. LCD display device i! (LCD)2.

The printer is equipped with a thermal transfer printer 3 which is a printer capable of changing the dot pitch for printing created documents.

Further, a floppy disk drive (FDD) 4 can be installed as an external storage device for storing documents and character patterns.

As shown in FIG. 2, the print head 3a of the thermal transfer printer 3 has two types of dots PIy with different pitch widths.
P2 is provided, and can be switched and used at any time during printing.

FIG. 3 is a block diagram functionally showing the overall configuration of this document creation device.

The keyboard 1 includes character keys such as kana, alphabets, numbers, and symbols, as well as other function keys, and a liquid crystal display device 2.
1 displays document information, layout information, etc., and the thermal transfer printer 3 prints document information, etc.

The input control section 10 takes in input data from the character keys and function keys of the keyboard 1, and outputs it to each processing section according to the contents.

The editing processing section 11 inputs character data from the input control section 10 and stores it in the one-character data storage area 12, and controls the display control section 14 according to the display format taken out from the format data storage area 13. Characters are displayed on a liquid crystal display device 2.

At this time, the storage location of the 5 character data in the character data storage area 12 is the liquid crystal display! Depending on the character data displayed in 2 and the cursor position.

The editing processing unit 11 judges and decides.

This editing processing section 11 further inputs attribute data specified by a character string or character unit using a function key from the input control section 10, and places the attribute data immediately before the corresponding character data stored in the character data storage area 12. is inserted, and the 1 display control unit 14 is controlled to display the attribute in the corresponding character portion of the liquid crystal display device 2.

The size conversion unit 15 controls the print control unit 16 to change the head data buffer 17 to the basic font size based on the attribute instruction data for size conversion and the basic font size instruction data from the keyboard 1, and then changes the head data buffer 17 to the basic font size. The head data buffer 17 is rewritten according to the attribute bit.

When the print processing unit 18 receives a print start instruction from the keyboard 1 via the input control unit 10, the print processing unit 18 executes the editing processing unit 11.
The print format is taken out from the format data storage area 13 and the character data is taken out from the character data storage area 12 through the print control unit 1.
Output to 6.

The print control unit 16 inputs this print data.

After the character generator converts the font data into font data consisting of character patterns in one day, the font data is stored in the print data buffer 20.

The print control unit 16 also includes a print data buffer 20.
The font data of the printer 3 and the contents of the herad data buffer 17 are detected in synchronization, and the font data of the helad data buffer 1 of the printer 3 is detected.
The font data is output to the head side indicated by the content of 7 and printed.

Next, regarding the operation of this embodiment configured in this way,
This will be explained with reference to FIG. 4 and subsequent figures.

First, the editing process executed at the time of data input will be explained with reference to FIG.

In this process, it is determined whether the data input from the keyboard 1 is data that indicates an attribute or not, and if the data is not data that indicates an attribute, the process shifts to other processing depending on the type of data.

When the input data is data that specifies an attribute, the editing processing unit 11 controls the display control unit 14 to detect the character at the position where the cursor is displayed, that is, the character whose attribute is specified, and stores one character data. The position of the corresponding character data is determined from among the character data stored in the area 12, and an attribute code is inserted immediately before the character data.

Turn on the bit of the insertion code according to the attribute.

Then, the character at the cursor position is displayed again in a format that matches the specified attribute, and the process ends.

Here, there are three types of attributes, which are expressed on the display of the liquid crystal display device 2 as underlined characters, white characters, or bold characters.

6th [i! ! I (,) specifies the attribute of the character string "Eokakikukeko" in the character string "Aiu...Seso" input as described above, and redisplays it as an underlined character. This is an example of the display when

Next, the processing executed during printing will be explained with reference to FIG.

In this process, first, the liquid crystal display device 2 is displayed as shown in FIG.
A printing condition specification screen as shown in b) is displayed.

In the figure, the "basic font size" is 1.
@ Specifies the font size to be used when printing normal character data that does not have a gender code added, and the "r phono 1 ~ change attribute" is an attribute that allows printing in a size other than the specified basic font size. This specifies the type of

For example, when specifying the conditions r12PJ and "underline" as shown in Figure 6(b), normal characters are 1
Print in 2 points, underlined characters only l0
Print at 85 points (outline characters and bold characters for which attributes are specified are printed at the standard font size if no conditions are specified).

After displaying such a printing condition designation screen, the operator inputs designation conditions in the flowchart of FIG. 5 and sets the basic font size.

Then, the character data at the print start position is searched from among the character data stored in the single character data storage area 12, and the print format is taken out from the format data storage area 13.

Next, the process moves to printing on a line-by-line basis, and first, a line format for one line is developed from the print format, and then character-by-character development is performed.

After clearing the print data buffer 20, one line of character data to be printed is taken out from the one character data storage area 12, converted into font data by the character generator 11, and then set in the print data buffer 20.

Next, it is determined whether or not it is necessary to switch the font size, and if there is no need to switch the font size, the process moves to attribute processing (not shown).

When it is necessary to switch the font size, the attribute code of one line of character data taken out from the character data storage area 12 is expanded, converted into attribute data, and then set in the head data buffer 17.

Then, mark each character from the print data buffer 20:
1 data is output to printer B, and when the attribute is changed by referring to the head data buffer 17, the print head of printer B is switched.

The above process is repeatedly executed, and after printing of one line is completed, it is determined whether printing of all lines has been completed, and if printing has not been completed, the printing process for each line is executed again. Then, when all lines have been printed, the process ends.

In addition, Figure S (c) shows the print result when the character data "Aiu...Seso" shown in Figure (a) is printed under the printing conditions shown in Figure (b). In this example, only the underlined characters ``Eo...ko'' are ``l''.
015 points are printed in small size, and the other normal characters ``aiu'' and ``sashisu seso'' are printed in large size at 12 points.

In this way, in this document creation device, attributes are specified for each character string or character, and characters are underlined depending on the type of the specified attribute.

By displaying white characters, bold characters, etc., and specifying the character size for each attribute when printing, when inputting data with different character sizes, it is possible to change the character by inserting control characters, etc. There is no shift, the display is close to the printed image, and the font size can be changed even after data is input.

Although a thermal transfer printer is used in this embodiment, the present invention is not limited to this, and any 4L printer that can change the pitch of the drum, such as a laser printer or an inkjet printer, can be used.

Effects As explained above, according to the present invention, in a text creation device equipped with a printer capable of changing the dot pitch, one
It should be possible to significantly reduce the deterioration in operability caused by changing the font size while creating a document.
