Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to display control of a character information processing device such as a text editing device.

Generally, when controlling text editing according to the document size in a text editing device, etc., the entire character information contained in A4 size or B4 size is projected on the display screen, and the text is edited according to the document size while looking at the display screen. format control (editing control)
It is desirable to do so.

However, in order to display the entire text information group of A4 or B4 size on the display screen as described above, a display device with a very large screen is required. Conversely, if the CRT display screen that is commonly used is, for example, 80 characters x 25 lines, and the character size is about 10 characters/inch x 6 lines/inch, the A4 size is 210 mm x 297 mm (8.27 x 11.69
inch), and it was not possible to display an A4-sized sheet of paper on this one screen, so the only option was to reduce the size of the characters displayed.

Therefore, in the former case, the device is very expensive because it requires a large-screen display device, and in the latter case, the displayed characters are small and difficult to read on a monitor etc. during character input operations, making it difficult for the operator to read the characters. It was a great deal of stress.

In view of the above-mentioned problems, the present invention displays characters of a size that is easy to read on a monitor etc. during character input operations, and when viewing the layout of the entire document size, the characters of one page are displayed on one screen. Information is compressed and displayed in a pattern depending on the presence or absence of characters, and the layout of the entire document size can be seen by displaying the pattern.

In particular, the layout of the entire document size and the character information at the input position as a monitor when inputting characters are displayed on the same screen.In other words, a monitor display area is provided in a part of the screen and input while viewing the layout of the entire document size. The character information of the position can also be visually confirmed, and the text can also be edited in this display state.

An embodiment of the present invention will be specifically described below. FIG. 1 is a block diagram showing the configuration of a character information processing device according to the present invention. In FIG. 1, 1 is a keyboard device having character input keys and control keys, and generates coded signals of input keys. and supplies it to the editing control circuit 2.

The editing control circuit 2 is a circuit that controls an editing function generally known as a text editing device,
The text is edited according to a predetermined text format, and the text information is sequentially stored in the text memory 3.

Reference numeral 14 denotes an input position indicating circuit, which is composed of, for example, a cursor counter, and stores information corresponding to the position of a cursor symbol to be displayed on the display screen. Then, in accordance with the operation of the cursor keys of the keyboard device 1, the position information can be changed to the corresponding position information.
This position information is supplied to the address control circuit 4 of the text memory 3 and the CRT display device 12.

5 determines whether the character information stored in the text memory 3 is a space character or not, and sends a code signal for changing the determined plurality of characters into one pixel (corresponding to the number of display pixels for one character). This is the circuit where this occurs.

For example, as shown in Figure 2, a normal one character block 1
2×3 display characters are displayed with or without the symbol S. In this Figure 1, the first column (1-1) of the first row, the second column (2-2) of the second row, the first column (3-1) of the third row, and 2nd column (3
-2) The symbol S is displayed to indicate that a display character exists there, and the second column (1-2) of the first row and the first column (2-1) There is no symbol S displayed there, indicating that there are no displayed characters. And the 2×3 in Figure 1
There are 64 types of patterns made from each matrix, and the corresponding pattern is selected depending on the state of the characters in the matrix.

Then, information for one page of the document size designated in advance by the editing circuit 2 is converted into a code for selecting the pattern and introduced into the format memory 6.

The format memory 6 is connected to the raster scanning circuit 1.
The address control circuit 7 is controlled by the address control circuit 7, which is controlled by the address control circuit 7.

8, by inputting the format code signal,
This is a pattern generation circuit that generates a corresponding pattern, which is read out and supplied in synchronization with raster scanning of the CRT display device 12.

Reference numeral 9 denotes a message memory for storing character information for one line at the input position, which stores character information for the line designated by the input position instruction circuit 14, and is controlled by the A signal from the raster scanning circuit 13. The data is read by the address control circuit 10.

The information read from the message memory 9 is supplied to a character pattern generation circuit 11, which outputs a character pattern in synchronization with raster scanning and supplies it to a CRT display device 12.

The raster scanning circuit 13 includes a counter controlled by a reference clock signal, and a synchronizing signal D for horizontal and vertical deflection to the CRT display device 12.
, a timing signal B output for each pixel in the format display period 20 of the display screen shown in FIG. 3, a timing signal A output for each pixel in the character display period 21, and a timing signal A output for each pixel in the character display period 21. A timing signal C synchronized with the timing signal C is outputted, respectively.

Next, the operation of the configuration shown in FIG. 1 will be explained.

First, character information regarding a sentence to be created is inputted from the keyboard device 1, and the character information is stored in the sentence memory 3 in advance.

Further, depending on the position of the cursor key, the page to be displayed in the text memory 3 and the line at the input position are designated. At this time, the input position instruction circuit 14 has the following information:
The input position is memorized.

The character information for the specified page is supplied to the format code signal generation circuit 5, and the format code signal is stored in the format memory 6 in correspondence with the text. The information on the line indicated by the input position indicating circuit 14 is stored in the message memory 9.
is stored in

On the other hand, the raster scanning circuit 13 is connected to the CRT display device 1.
When the second scanning position is in the format display area 20 (FIG. 3), the B signal is output. For this reason, a code signal is outputted from the format memory 6 in synchronization with raster scanning, and the pattern signal is read out by the pattern generation circuit 8, and the area of the display area 20 is displayed as shown in FIG.

Further, during the period when the scanning position of the CRT display device 12 is in the display area 21, the A signal is output from the circuit 13, and the message memory 9 is output in synchronization with the raster scanning.
The character code is read out, and a corresponding character pattern is derived from the character pattern generation circuit and displayed as shown in FIG.

Input position information is supplied to the CRT display device 12, and the input position is determined by displaying a cursor mark at the corresponding character position in the format display area 20 or by blinking pixels corresponding to one character. indicate. Further, a cursor mark is displayed in the display area 21 at the corresponding character position 22. Therefore, the operator can see where the input position is in the document from this display.

When the cursor key is moved to the next or previous line, the information in the input position indication circuit 14 changes accordingly, and the corresponding line is selected from the text memory 3 according to this information. The character information is transferred to the message memory 9 again, and the document in the line at the operated position is displayed in the display area 21. Furthermore, the cursor position in the format area 20 also changes accordingly.

Note that another use of the character display area 21 is to display operation (control) information for the operator. This allows the operator to identify whether the data is to be corrected, deleted, or printed.

As described above, the display control device of the present invention can display the entire layout in a predetermined symbol pattern that is easy to see for each document size, and also displays character information such as input position on a part of the screen on which the symbol pattern is displayed. can be displayed on the monitor, both the layout and the monitor can be displayed using one display device, and text can also be edited in this display state.
