Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a word processor, and more particularly to a word processor equipped with a display device.

A display device in a word processor is used to check characters or symbols (hereinafter simply referred to as characters) input from an input device, to check characters that have already been input, or to check the recorded layout of characters. However, in word processors that handle Japanese text, the character pattern of one character is divided into 24 dots in the horizontal direction and 24 dots in the vertical direction.
It is composed of a matrix pattern of dots,
It is difficult to display a string of character patterns of 60 characters horizontally and 40 characters vertically on a typical paper size (e.g. JIS, A4 size) on a typical CRT display device in a layout similar to that of the recording. be.

Therefore, in conventional word processors of this type,
A display device for character pattern display and a display device for layout display may be provided separately, or a single display device may be used to switch between character pattern display operation mode and layout display operation mode and display them as separate images. Ta. However, in the former case, the character pattern and layout are displayed at the same time, but since the two screens are located far apart, the amount of eye movement required for confirmation increases, which increases the fatigue of the operator. There was a drawback that two display devices had to be provided. In the latter case, the character pattern and the layout cannot be displayed simultaneously, and the operator must memorize one of the images.

On the other hand, in order to display character patterns on a single screen in a layout similar to the recording, it is possible to improve the screen resolution of the display device or increase the size of the device, but this would increase the price and
There is a problem that the entire device becomes larger. Furthermore, it is conceivable to reduce the number of dots constituting the character pattern displayed on the display device, but this would result in a smaller display character pattern and a reduction in the number of characters that can be expressed. Furthermore, since a printer attached to a word processor is required to print high-quality character patterns, if a dot printer is used, a character pattern generator for the printer must be added.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a word processor that can simultaneously display required character patterns and layouts on the same screen using display devices of common resolution and size.

In order to achieve this object, the present invention converts a character pattern to be displayed on a display device into a layout pattern except for a predetermined area of the screen so that only the presence of characters is reduced and displayed, and this predetermined area is It is characterized by being movable by input from the user.

According to one embodiment of the present invention, when the word processor is used in the input operation mode, the line at the input position (cursor position) and the character strings in the two lines above it are displayed as a character pattern; In the upper area, the character code is converted into a layout pattern, reduced to 1/2 the size, and displayed simultaneously and consecutively on the same screen in a layout similar to the recording, and used in the correction operation mode. In the state where
Displays the line at the cursor position and one line each above and below it as a character pattern, and for the other areas, converts the character code into a layout pattern and divides it into half.
It is reduced to the size of , and displayed simultaneously and consecutively on the same screen in a layout similar to that of the recording.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

In FIG. 1 showing the overall structure of a word processor, numeral 1 denotes an input device such as a keyboard or tablet for inputting desired characters or operation modes, and inputs character codes or operation command codes to the control device 2. The control device 2 temporarily stores codes such as characters inputted from the input device 1, reads pattern information to be displayed from the pattern generator 4, sends it to a display device 3 such as a CRT display, and displays it. The output device 5 is a printer that outputs text edited by operating the input device 1 as a hard copy.

FIG. 2 is a detailed block diagram of the control device 2.
The control device 2 includes an overall control device 6, a system storage device 7, a display division control device 8, and a refresh memory 9. The overall control device 6 is
It is composed of a control circuit centered on a so-called microcomputer, and controls input, storage, display, and output in the control device 2. The display division control device 8 is a device for displaying character patterns and layout patterns, and is composed of a so-called selector circuit, which converts address information of the character pattern generator 4 sent from the overall control device 6 into cursor position information. If the character pattern itself is to be displayed as selection information, it is sent as is to the refresh memory 9 as address information of the character pattern, and if a layout pattern is to be displayed, it is sent to the character pattern generator 4 in which the layout pattern is stored. address information and sends it to the refresh memory 9. For example, if the address of the character pattern generator 4 where the layout pattern is stored is address 0, when a character pattern is to be displayed, the address information of the character pattern generator 4 sent from the overall control device 6 is If the address information of the character pattern is to be sent as is to the refresh memory 9, and the layout pattern is to be displayed, it is forcibly converted to the address information of address 0 and sent to the refresh memory 9, and these are temporarily stored in the refresh memory 9. Make me remember. Character codes input from the input device 1 are controlled by the overall control device 6 and temporarily stored in the system storage section 7. Further, the overall control device 6 reads character codes to be displayed on the display device 3 in the order in which they should be displayed on the display device 3, and sends them to the display division control device 8. Further, line designation information indicating which line of the display column of the display device 3 is specified from the input device 1 (the line where the cursor is displayed: x line, y line) is sent from the overall control unit 6 to the display division control unit 8. is input to. In the input operation mode, the line designation information x corresponds to the final input line, and the display division control device 8 corresponds to three lines: x line, (x-1) line, and (x-2) line. For the character code, refresh the address of the corresponding character pattern in the pattern generator 4, and for the other character codes from line 1 to (x-3), refresh the address of the layout pattern of the pattern generator 4. It is sent to memory 9 and stored temporarily. In addition, in the correction operation mode, the line designation information y is the cursor display line y controlled by the cursor movement input, and the display division control device 8 is configured to display the cursor display line y, (y-1) line, (y+
1) Refresh the address of the corresponding character pattern in the pattern generator 4 for the character codes corresponding to three lines, and the address of the layout pattern of the pattern generator 4 for the character codes of the other lines. It is sent to the storage memory 9 and temporarily stored therein. The contents of one screen of the display device 3 temporarily stored in the refresh memory 9 are read out by the overall control device 6, converted into a pattern by the pattern generator 4, and are continuously displayed on the same screen of the display device 3. Display simultaneously (visually).
