Description

Detailed Description of the Invention (a1 Technical field of the invention) The present invention relates to a display device such as an information processing device, a document creation device called 9', etc. This invention relates to a cursor used as a mark to indicate a manually displayed position.

(b) Background of the technology In recent years, advances in display devices have made them multi-functional, making it possible to display various data such as graphs, images, and other images in addition to text.

Therefore, the contents and shapes displayed on the screen vary widely.

FC + Conventional Technology and Its Problems By the way, the cursor that marks the position on the screen where the next input should be displayed only has a shape preset by the manufacturer, and when handling data on the screen, the display The shape of the content and the shape of the cursor may be confusing, making it difficult to recognize the position of the cursor.

For example, as shown in Figure 1, there are relatively many underline-shaped cursors 2 whose length is about the same as the width of a single character 1, but this is not the case when dealing only with sentences.
For example, when dealing with content that has many straight lines parallel to cursor 2, such as mathematical formulas or graphs such as -゛ or °゛-゛, cursor 2 may be confusing because it looks similar to the displayed content. Hard to recognize. When the underline is actually drawn, it is particularly thin at 4'II. Therefore, there is a method that makes the cursor blink, but when you operate the cursor while facing the setting screen, it is not only too noticeable and obtrusive, but it is also too irritating to the eyes and can cause eye fatigue. This is a major health problem. Is it preferable to use a non-flashing type, as mentioned above, it would be difficult to distinguish between the displayed content and the cursor, which would impair operability and reduce processing efficiency. Therefore, it would be convenient if the operator could freely select and use a cursor with an easily distinguishable shape depending on the content or shape of the data being handled on both sides.

(d1) Purpose of the Invention In response to such demands for conventional display devices, the present invention provides a method for selecting and conveniently selecting a desired cursor depending on the content being handled on the screen. Monthly.

(e) Structure of the Invention In order to achieve this object, the present invention provides a cursor memory turtle that stores various cursor shapes in a display device that displays sentences, graphs, illustrations, etc. From [4], a configuration is adopted in which a cursor of a desired shape can be selected and used by providing means for specifying the shape of the cursor to be displayed.

(f1 Embodiment of the Invention) Next, how the display device according to the present invention is actually embodied will be explained using an embodiment. FIG. 2 is a block diagram showing the configuration of the display device. 3 is a display The device A is an external device such as a keyboard 1- or a central processing unit.The display device 3 includes a display unit 5 such as a CRT, and a display unit 5 that maintains display information on the display unit 5, a display unit 6, and characters. The refresh memory 6 is equipped with a character cheneleke 7 that stores the pattern of .
only input.

In the case of the present invention, in addition to these defeats, various cursor shapes 1]< are stored in the memory. For this purpose, a cursor memory 8 is provided, and a plurality of cursor patterns are registered in this cursor memory 8. The person who wants to register the cursor shape manually sets the address to be registered in the address register 9 of the cursor memory from the external device 4, and transfers the data of the cursor shape via the data bus 10 to the cursor memory 8. Enter and store. In this way, various cursor shapes, such as an uncured line shape, a star shape, and a cursor shape, are registered for each cursor/response.

When using the display device, C inputs the address of the cursor of the shape he wants to display from the external device 4 such as a keyboard into the address register 9 and outputs a cursor display command. Read the cursor shape corresponding to the specified Arres in 8,! Display unit 5 via the OR circuit 11
Enter and display. Since the refresh code and the video message from the memo υG are also input to the OR circuit 10, data such as characters, graphics, and images are displayed together with the cursor.

Since the cursor shape can be selected in this way, it is possible to select and use a cursor with a shape that is not easily confused with the displayed content, depending on the content to be processed on the screen. If you want to use a different cursor because the content displayed on the screen has changed so that it can no longer be confused with the cursor, you can specify the address of another cursor from the external device 4 and display it. .

Therefore, when handling text such as when creating a document, use the underline-shaped cursor 2 explained in Figure 1, and when drawing an underline or processing graph ink or images, use the underline cursor 2. You can specify and use a cursor with unusual shapes such as stars or ears.

Naori - If a ROM or the like is used as the cursor memory 8 and cursors of various shapes are registered in the cursor memory 8 in advance, the user cannot freely register the cursor shape, and the data bus 10 will also become unnecessary.

(g) Effects of the Invention As described above, the present invention includes a cursor memory for recording various cursor shapes, and each time the address of the cursor shape to be displayed is specified from an external device such as a keyboard, You can select and use a cursor of the desired shape. Therefore, depending on the content to be processed on the screen, it is possible to freely select and use a cursor with a shape that is difficult to confuse with the displayed content. As a result, the position of the cursor can be easily and accurately recognized, improving interactivity between man and machine, and making it possible to work efficiently. Moreover, the cursor is blinking.
(However, since the cursor position can be recognized, it does not cause eye fatigue and is extremely useful for health management of operators.
