Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device that allows confirmation of the actual size on paper, such as the position of a document displayed by a display means.

[Prior art and its problems] Conventionally, display devices such as word processors have been able to express only physical relative relationships such as sentences and paragraphs thereof.

Furthermore, even if it were possible to display the size of the paper and the text in their actual sizes, the dimensions of the paper and text positions could not be obtained from the display and had to be printed. For example, 4cm×
If you want to make room for a 5cm photo, the operator has to guess and make edits based on the line pitch, character pitch, paper size, etc., and the inconvenience of not knowing the actual size until you actually print it. It was hot.

[Means and effects for solving the problem] In order to solve the above-mentioned inconvenience, the present invention determines where the text is physically placed (printed) on the paper before printing. By providing a means for displaying detailed dimensions on the screen, it is possible to obtain information on the actual size, which conventionally could not be known without printing.

[Example] Hereinafter, an example according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. In the figure, 1 is the keyboard, and the 2nd
As shown in detail in the figure, this keyboard 1 is used to input characters, set the left margin, set the number of characters per line, set the character pitch, and specify paper size, paper size per dot, etc. Key 1A, cursor movement key 1 to move the cross cursor
B, and a pointing key 1C for indicating the position of the current cross cursor reel.
2 is a keyboard control circuit; 3 is a microprocessor which is a CPU that controls the entire embodiment according to a program stored in a ROM 4 as shown in FIG. 4, which will be described later; and 4 is a microprocessor, as shown in FIG. remembers micro programs
ROM, 5 is a CRT display, 6 is a CRT display control circuit, and 7 is a refresh memory for the CRT display. The recorded dot information in the refresh memory 7 of the CRT display corresponds to the display pixels (display dots) of the CRT display 5, and when a dot row is written in the refresh memory 7, the dot row written in the CRT display 5 is The corresponding dots can be displayed. 9 indicates data such as memorizing the created text and setting the left margin using the key 1A mentioned above, number of sentences per line, character pitch, paper size (paper size D per dot), etc. and 8 a printer that is activated by pressing a print command key (not shown) on the keyboard 1 and prints the created text.

Figure 3 shows an example of a text layout displayed on a CRT display.

In the figure, a large rectangular frame 11 represents a sheet of paper, and within it, horizontal lines 12 indicate sentences.Although the contents of the sentences are not displayed, the layout of the sentences developed on the sheet of paper is different from the actual size. This is an example of how the image is displayed. In this case, it is of course possible to display the input text as it is on the CRT instead of the horizontal line. 13 and 14 represent cross cursors. The size of this frame 11 does not change on the display even if the selected paper changes, so the actual size of one dot on the CRT display will vary depending on the selected paper size. It is something that is present.

FIG. 4 is a flow chart of the operation control of this embodiment, which is achieved by a microprogram stored in the ROM 4.

The details of the operation of this embodiment will be explained below based on the drawings.

First, use keyboard 1 to create a sentence,
The layout of this text is displayed on the CRT display 5. However, in the display of this embodiment, the content of the created text is not displayed, but the layout of the document on paper is displayed as a ratio of the actual paper size to the text. However, in this case, it is of course possible to display the text itself. The CRT display 5 is composed of 1024 vertical x 1024 horizontal display dots, and two-dimensional coordinates are set with the upper left dot on the screen as the origin, the horizontal direction as the x direction, and the vertical direction as the y direction. I'm getting better at it.

In Figure 3, in the space at the bottom right, 12cm high x 8cm wide
The fourth operation is to check whether the photo is swollen.
The process will be explained below based on the flowchart shown in the figure.

After displaying the layout, the microprogram of this embodiment enters the processing shown in the flowchart of FIG. The operator moves the cursor to the position of the cross cursor 13 in FIG. 3 using the cursor movement key 1B while waiting for input in step 21. If there is a key input in this state, it is determined in step 22 of the flowchart in Figure 4 whether it is a cursor movement key or not, and if it is a cursor movement key, the process is performed in step 23 to move the cross cursor. .

When the cross cursor reaches position 13 in FIG. 3, the operator presses the pointing key 1C. Then, according to the judgment in step 22, proceed to step 24.
Then, it is determined whether or not the pointing key 1C is pressed. If the pointing key is not 1C,
Also, the process returns to step 21 to wait for a key input, and if it is a pointing key, the process of step 25 is executed. Here, the microprogram reads the two-dimensional address (x ₁ , y ₁ ) of the cross cursor,
This address is stored in RAM 9, and the next position input is awaited in step 26.

Next, the operator moves the cursor to the position of the cross cursor 14 using the cursor movement key 1B. If there is a key input for moving the cursor, the microprogram makes a judgment in step 27, and since it is a cursor moving key input, it performs the processing in step 28 to move the cross cursor, and returns to the key input waiting state in step 26. After moving the cross cursor to the position shown in FIG. 3, the operator presses the pointing key 1C to input. Then, the process jumps from the judgment in step 27 to the judgment in step 29, and if it is determined in step 29 that it is not the pointing key, the process returns to the key input waiting state in step 26. In this case, if the pointing key is input, the process of step 30 is executed. Then, read the two-dimensional coordinates (x ₂ , y ₂ ) of the cross cursor again, and in the subsequent step 31,
Calculate the distance between positions 13 and 14 in Figure 3, that is, √( ₂ − ₁ ) ² + ( ₂ − ₁ ) ² , and calculate 1 from the paper size specified in the calculation result.
This is the actual paper size per dot. “D”
Multiply by Then, in step 32, the calculation result is displayed at a predetermined position 15 on the CRT display 5. Therefore, the operator can know the actual distance when printed (in this case, the empty space), and can check whether a 12 cm tall photo can be pasted without actually printing the text. can be judged. You can also check whether it is possible to crawl in the horizontal direction using exactly the same operation.

[Effects of the Invention] As described above, according to the present invention, by displaying the actual size on paper, such as the position of a created sentence, it is possible to accurately and easily know the actual distance.

In addition, it has become possible to judge whether or not inserts such as photographs and graphs will be included in empty spaces without actually printing them.

Also, before printing, it is possible to give the operator a clear image similar to that of printing.
