Abstract

PURPOSE:To show a printing size of a document on a screen under display by calculating the scales showing the printing size/length by reference to the format information and displaying these scales on the display screen. CONSTITUTION:When a scale display mode is instructed by a scale instruction means 2, a scale production means 3 reads the format information out of a format information storage means 1. This format information includes the size of a character font, the numbers of lines and digits, the form sizes, the line digit pits, etc. Based on the format information, a scale is produced in accordance with the printing size set when a document displayed by a display means 4 is actually printed by a printing means. This produced scale is displayed on the means 4. Thus it is possible to accurately know the printing size/length on a display screen during the production of a document.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display processing device used in a word processor or the like.

[Prior Art] Generally, in word processors and the like, the format of a document is defined by setting the number of characters per line and the number of lines per page. Then, a document is created according to this format, and the created document is printed by a printer. On the other hand, this document that has been created or is being created is
It is displayed on a display unit such as a D (liquid crystal display). When creating a document, the creator inputs and edits document data while looking at this display section.

By the way, when printing a created document, there are cases where it is desired to secure an appropriate margin for inserting a photograph or the like in the printed text. Conventionally, in such cases, a scale for the display screen is displayed on the display screen being created, and the creator uses that scale to get a rough idea while creating the blank space. .

[Problems to be Solved by the Invention] However, in such conventional display processing devices, the scale displayed on the display screen is just a scale for the display screen, and the size and length when printed are It does not directly represent the Therefore, although the creator can determine the approximate size using the scale, there is a problem in that he cannot tell whether he has created a product of the desired size until he actually prints it. Also,
With conventional word processors, the scale on the display screen does not change even if you change the formatting information (for example, font size, number of lines, paper size, etc.) of the input text. If you want to leave an 8 cm x 8 cm space for later insertion of a photo, you will have to calculate the approximate value yourself based on line, column spacing, and font size. In any case, there is a problem in that the flow of document creation work is interrupted and the work cannot be done efficiently and quickly.

An object of the present invention is to make it possible to easily know the size, length, etc. at the time of printing on a document display screen.

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

The format information storage unit l (see the functional block diagram in Figure 1; the same applies hereinafter) stores format information when printing a document, such as character font size, line, number of digits, paper size, and line bit. RAM etc.

The scale instruction means 2 includes function keys (for example, a 10-key cursor movement key) for instructing the display means 4 to display a scale, and soft keys displayed on the display means 4 by the function keys.

The scale creation means 3 creates a scale to be displayed on the display means 4 based on the format information stored in the format information storage means 1. In this case, a scale is created based on the format information so that a scale corresponding to the size at the time of printing is displayed on the display means 4.

The display means 4 displays the scale created by the scale creation means 3, and is, for example, a CRT.

LCD etc.

[Effect] The operation of the means of the invention is as follows.

When scale display is instructed by the scale instruction means 2, the scale creation means 3 reads out format information such as character font size, line, number of digits, paper size, line bit, etc. stored in the format information storage means 1. , a printing means (printer, etc.) for printing the document displayed on the display means 4 based on the format information.
Create a scale that corresponds to the actual printing size. The created scale is then displayed on the display means 4.

Therefore, the print size on the display screen during document creation,
The length can now be known accurately, eliminating the need for trial printing and calculations, increasing the efficiency of document work.

[Example] Examples will be described below with reference to FIGS. 2 to 10.

2 to 5 are diagrams showing a first embodiment of the display data processing device.

First, the configuration will be explained. FIG. 2 is a block diagram of the display data processing device. In this figure, 11 is a CPU that controls the entire device and performs various document processing including display processing, which will be described later, and cpull controls various operations of the screen display processing device according to microprograms stored in ROM 13, which will be described later. Control. The CPU II includes an input part 12 consisting of a keyboard equipped with keys for document input, function keys, etc., a ROM 13 that stores a microprogram for control, an input buffer 14 that stores character codes input from the input part 12, A document memory 15 that stores information about the document being created, a format information storage section 16 that stores format information such as character font size, line, number of digits, paper size, line pitch, etc., and a display that displays input and edited documents. A display memory 18 that stores display data to be displayed on the section 17 and a print control section 21 that controls a printing section 20 that prints out a document are connected to the display memory 18 . Further, the display section 17 is controlled by a display control section 19.

The input unit 12 is a keyboard equipped with character keys for inputting characters, function keys for editing and correction, cursor movement keys, etc. Here, the scale display function is specified using the function key 12a, and the scale display position is specified. and length are specified using the cursor keys 12b and confirmed using the function keys. That is, when a predetermined function key is pressed, keys such as "Scale 1 processing" (first embodiment), "Scale 2 processing" (second embodiment), rOther word processing" etc. are displayed on the display screen of the display unit 17. are displayed, and by selecting the soft keys displayed on the display screen using the 10 keys, the display processing or other processing of this embodiment is executed.

The display memory 18 includes a character code section that stores display character codes, and a graphic display section that displays graphics (circles, figures, pictures, etc.).

Since the graphic display section and the character code section are independent and are combined on the screen, the graphic display will not be erased by writing characters.

Further, the printing section 20 is for printing out the document stored in the document memory 15 according to format information set in advance by the creator.

Next, the operation of this embodiment will be explained.

FIG. 3 is a flowchart showing the main flow of word processor processing, and this flow is executed after an initial state such as power-on/reset. In the figure, the symbol Sn (n
=1.2. ...) indicates each step of the flow.

After the initial state such as power-on, the system first waits for key input at step SIO, and when a predetermined function key is input,
“Scale 1 processing” (first
Embodiment), "Scale 2 processing" (Second embodiment), "Other word processing", etc. are displayed.
By selecting these soft keys using, for example, the 10 key, various processes such as scale 1 processing (step 5ll), scale 2 processing (step 512), and other word processing processing (step 513) are executed. Here, other word processing processing shown in step S13 includes normal word processing processing such as kana-kanji conversion processing. That is, assuming that this step S13 is a kana-kanji conversion process, here, when a character is input from the input section 12, the CP
The information is sequentially stored in the input buffer 14 through the UII, and is expanded into dots on the display memory 18 and displayed on the display section 17.
will be displayed. In addition, after manually inputting the kana character string to be converted using the character keys, the CP can be converted by operating the conversion keys.
Kana-kanji conversion processing is performed in the UII, and when the character code after the kana-kanji conversion is determined, it is written to the document memory 15, and the kanji converted to kana-kanji is displayed on the display unit 1.
7 is displayed.

By the way, when "Scale 1 processing" displayed on the display screen is selected using the function key while waiting for key human power in step SIO, the screen display processing flow shown in FIG. 4 is started.

First, in step S20, format information such as character font size (number of points), line, number of digits, paper size, line digit pitch, etc. set in advance by the operator is read from the format information storage unit 16, and the format information is read out. Calculate the length on the display screen that corresponds to the distance when actually printed by referring to it. Next, in step S21, as shown in FIG. 5, the calculated vertical and horizontal scales 31 are graphically displayed together with numerical values 31a, with units (for example, CITl) attached, at predetermined positions on the display screen 32 that do not overlap with the characters 33. Finish the processing of this flow. To explain specifically, when a sentence is input in each column of each line on the display screen of the display unit 17 and the text on the display screen is to be printed by the printing unit 20, the horizontal direction of the printed sentence is The length is calculated as [font of text x number of characters, cross spacing x (number of characters - 1)], and the vertical length of the text is [font of text x number of lines, distance between tens of lines x (number of lines - 1)]
” is calculated. Further, the vertical and horizontal sizes of this text can be calculated based on the above-mentioned format information, and the actual dimensions when the text on the display screen is actually printed can be known. Then, the actual dimensions (distance) when the text displayed on the display screen is printed are displayed on the display screen together with units as vertical and horizontal scales.

As explained above, in this embodiment, the actual printing length is scaled and displayed on the display screen based on the format information rather than the number of characters, so there is no need to print the printing size. This can be seen on the display, greatly improving document creation work. In addition, because it allows you to see more detailed positional relationships than the conventional display of printed images, it is especially useful for word processors with a lot of formatting information (e.g., multiple fonts, various paper sizes, etc.).
(Word processor that allows you to specify character and line spacing in 1mm increments)
It is effective when applied to

In this embodiment, the scale calculation is executed at any time when the cursor is moved using the function key and "Scale 1 processing" is selected on the screen, but this is not limited to this. If the number is small or there is enough memory, calculate and memorize the length per unit on the screen for each format in advance, and multiply it by the length between the cursors when displaying the scale to get the scale value. You may also leave it as .

Also, if you can fix the length of the scale so that the scale is always the same size on the screen even if you change the format, for example, if you want to insert one character in 12 cm, By fixing the scale at 12 cm and changing the format one after another, it is possible to find the optimal one. In this way, by being able to fix the length of the scale, even if the paper size does not meet the standards such as A4 or 84, it will be easier to select a format that will fit the characters properly within the paper size. There is an advantage.

6 to 10 are diagrams showing a second embodiment of the display processing device, and this embodiment displays a scale between any two points on the display screen. The hardware configuration of this embodiment is similar to that of the first embodiment.

FIG. 6 is a flowchart showing a program for display processing, and this flow is executed by pressing the function key "Scale 2 processing" when waiting for human power in the third step SIO mentioned above.
is executed by being selected.

First, in step S31, the system waits for key power as in the case immediately after power-on. When a key is manually pressed, in step S32, this key is manually pressed for cursor 1 and cursor 2.
It is determined whether the return key is manually operated to fix or release the key.

If the return key as the execution key is not operated at this point, it is determined that cursor 1, which is the starting point of the scale, has not been fixed yet, and it is determined in step S33 whether or not the cursor movement key is operated. do. When the cursor movement key (here, cursor 1) is operated, in step S34, cursor 1 is freely operated on the display screen 32 on which characters 33 are displayed as shown in FIG. 7, and cursor I is displayed with a scale. move it to the desired position, which will be the starting point when Further, if the cursor movement key is not operated, the process returns to step S31. Note that during this first cursor movement, cursor l and cursor 2 are displayed together on the display screen 32, and cursor 1 for determining the starting point of the scale is displayed on the display screen 32.
only shown. Next, the process moves to step S35, and it is determined in step S35 whether cursor 1 is fixed, but at this point, cursor l is being moved or cursor 1 has been moved to the desired position. Since the cursor 1 has not yet been fixed since it is just after that, the process returns to step 331 and waits for the key to be pressed. Then, in step S31, a key is manually operated, and in step S32, when it is determined that this key is manually operated as a return key, the cursor 1 is moved to a desired position, and the operator requests a scale starting from this position. It is determined that the process has been executed, and the process moves to step S36. Further, if the return key is not operated, it is determined that the position of the cursor 1 has not been determined yet, and the process proceeds to step S33.

In step S36, it is determined whether cursor 1 is fixed or not, and if it is determined that cursor l is not fixed, the process moves to step 337.

After fixing the cursor l in step S37, cursor 2, which is the end point of the scale, is displayed in step S38, and the process returns to step S31. As a result, as shown in FIG. 7, cursor 1, which is the starting point of the scale, is fixed at that position, and cursor 2, which is the ending point of the scale, appears at the same position.

Step S3 after fixing cursor 1 and displaying cursor 2
1, and when it is determined in step S32 that the key was not manually operated as a return key, it is determined that the operator has manually operated a key to move the cursor 2, and the cursor movement key is pressed in step S33. Determine whether or not it is being operated. When the cursor movement key (in this case, cursor 2) is operated, in step S34, as shown in FIG. Move it to the desired position that will be the end point for display. Also in this case, if the cursor movement key is not operated, the process returns to step S31. Next, in step S35, it is determined whether cursor 1 is fixed or not, but since cursor l has already been fixed here, the process moves to step S39. In step S39, the scale in the X-axis direction is calculated according to the subroutine shown in FIG. 9, which will be described later, and the scale 41 obtained by calculation as shown in FIG. The screen is displayed in a graph-like manner and the process proceeds to step S40. In step S40, as in step S33, the scale in the Y-axis direction is calculated according to the subroutine shown in FIG. 9, and the calculated vertical scale is graphically displayed together with the numerical value and unit, and the process returns to step S31.

Note that the X-axis direction and Y-axis direction with respect to the display screen 32 are
As shown in the figure, the coordinates of cursor 1 and cursor 2 are (X,, Y,) and (x,, y,), respectively.

After calculating the scales in the X-axis direction and the Y-axis direction and displaying them, a key is manually operated in step S31, and if it is determined in step S32 that this key manually is a return key key operation, the process advances to step S36, and the cursor is moved in step S36. Determine whether or not 1 is fixed. When it is determined that the cursor 1 is fixed, the return key is operated after displaying the scale, and therefore the operator determines that the operator has operated the return key after using the scale display, the process moves to step 841, and the display is displayed in step S41. Return the screen display to its initial state and end the current process.

In this way, when "Cursor 2 processing" in Figure 6 is selected and executed using the function key, move the cursor to the leftmost cursor position (see part m) in Figure 7 and press the return key. Cursor 1 is then fixed at that position, and another cursor 2 is displayed at the same position. Here, when the cursor right key is pressed, a scale 41 is displayed between the position where the cursor 1 was previously fixed and the cursor 2 currently in use. Below the movable cursor 2 on the right side, the entire length of the scale (numerical value 41a) is displayed together with the unit, and this changes each time the cursor 2 is moved.

The cursor 2 can also be moved upward using the cursor up key, and in this case a vertical scale is displayed together with the numerical value. If you press the cursor right key again in this state, the vertical and horizontal scales will be displayed at the same time. These make it possible to know on the screen the distance between any two points when actually printed.

FIG. 9 shows a subroutine for calculating the scale between cursor 1 and cursor 2, and this routine is interrupted in step S39 or step S40 of FIG. 6.

First, in step S51, the number of characters, character spacing, and number of lines between cursor l and cursor 2 are calculated,
In step S52, these numerical values and format information storage unit 1
Based on the format information such as the size of the character font stored in 6, the length of the scale is calculated according to the following formula (2), and this routine ends.

(Character font size) x (number of characters between cursors 1 and 2) + (number of characters between cursors 1 and 2 (character spacing (horizontal)) 2 line spacing (vertical)
)...■ The above scale calculation process will be specifically explained using FIG. 10. FIG. 10 shows how the character font size, character spacing, and line spacing, which change according to the format during printing, correspond on the display screen 32. Since these do not change on the display screen 32,
The display scale changes according to the format.

Now, when cursor 1 and cursor 2 are placed as shown in Figure 10, from the positions of these cursors,
The number of characters and the number of characters between them are calculated according to formula 0. In this case, the number of characters between cursor 1 and cursor 2 is "4" and the number of characters between characters is ``3''', so by substituting this into the 0th formula, we get the following formula The length of is required.

(Character font size) x 1 + character spacing x 3... ■Note that in this example, the number of characters and the number of character spacing are integers, but these do not necessarily have to be integers; for example, if the cursor is Needless to say, it may be something that moves. Furthermore, if the positional relationship between cursor ■ and cursor 2 is diagonal, the vertical and product values can be calculated separately in the same manner.

As described above, according to the present embodiment, the number of characters, character spacing, and line spacing between cursor l and cursor 2 are calculated, and format information such as character font is referenced to these values to display them on the screen. The scale between any two points is calculated. In particular, in this embodiment, the scale corresponding to the length when printed at any position on the screen can be known on the display screen, so when you want to create a predetermined mark at an appropriate location in the document to be printed, etc. The workability can be greatly improved.

In each of the embodiments described above, an example was shown in which a horizontally written document is displayed, but the present invention is not limited to this, and it goes without saying that a vertically written document may also be displayed.

[Effects of the Invention] According to the present invention, the size at the time of printing,
The scale that indicates the length is calculated and displayed on the display screen, so you can know the printed size on the currently displayed display screen without actually printing or calculating it. The workability of the creation work can be greatly improved.
