Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is applicable to computers, high-performance calculators, and other display devices with two-dimensional expansion, and keyboards for inputting alphanumeric characters to these devices. This invention relates to a key-powered device for moving a cursor that is part of the device.

Configuration of conventional examples and their problems In recent years, many human-powered devices have been produced and sold, but all of them require the user to use the left, right, up, down, and directional arrows that the device has to move the cursor. By pressing a key, the device would move one unit in the direction indicated by the arrow, and by continuing to press the key, the device would move continuously by multiple units in the direction indicated by the arrow.

A conventional key-powered device for moving a cursor will be described below.

FIG. 1 is an external view of a conventional key-powered device for moving a cursor, and FIG. 2 is a block diagram showing its configuration.

FIG. 3 is a flowchart showing the processing contents of the microcomputer which is this component.

The operation of the conventional key-powered device for moving a cursor constructed as described above will be described below. In the conventional example, each time a key with an arrow for moving a cursor on the key-powered device 1 is pressed, this occurs at the input port 3. The data is taken into the microcomputer 2 via the memory 4, and from there, the microcomputer 2 issues a cursor movement command to the display device via the output port 5 according to the processing procedure shown in the flowchart of FIG. method was adopted. However, this method has the problem that it takes time to move the cursor to a far position on the display screen.

OBJECT OF THE INVENTION The present invention solves the above-mentioned problems of the conventional technology.
To provide a key-powered device for moving a cursor that can move a cursor at high speed even when the display screen is far away, by using it in combination with a conventional key-powered device with an arrow mark for moving the cursor. The purpose is to

Structure of the Invention The present invention provides a computer with a key input device for inputting numbers and alphabets, and a shift key input device separate from these keys to give different meanings to these keys. When displaying data and processing results input from these human-powered devices on a display device, these keys are used to move the cursor up, down, left, or right to indicate the next position to be displayed on this display device. If you use a cursor movement key with a cursor movement arrow on it, and then press the cursor movement arrow key and the shift key at the same time, the result will be faster than when the cursor movement key is pressed alone. This is a human-powered cursor movement device that can move the cursor at high speed, allowing you to move the cursor arbitrarily in a short amount of time even when it is far away on the display screen, making it extremely easy to operate. It is something.

DESCRIPTION OF THE EMBODIMENTS FIG. 4 shows an external view of a computer key-powered device including a key-powered device for moving a cursor in an embodiment of the present invention. FIG. 5 is a block diagram showing the configuration of the same embodiment. FIG. 6 is a flowchart showing the processing contents of the microcomputer which is a component of this embodiment.

The operation of the key-powered device for moving the cursor of this embodiment constructed as described above will be described below. While looking at the display screen, if the operator of this device wishes to move the cursor, he or she can press a key indicating the direction in which he/she wishes to move the cursor within the human-powered device 6, where the arrow for cursor movement is indicated. Press the current key. The pressed information is given to the microcomputer 11 via the input port 9° and the memory 1o. Then move the cursor one unit on the display screen,
Information that can be moved in the same direction as this arrow is given from the microcomputer 11 to the display device via the output port 12. If you continue to press the same key, the cursor moves continuously in the same direction, but this movement is slow enough that you can stop it at any point.

Furthermore, if the operator wishes to move faster, he or she can press the shift key 8 attached to this device at the same time, and the cursor will immediately move in the direction of the arrow displayed on the cursor movement key pressed from the front. It moves at high speed and can be brought instantly to the desired location by the operator.

When the operator gets close to the desired location, if the user releases the finger pressing the shift key, the cursor will slowly return to its original position and the operator can freely stop the cursor at the desired location. I can do it.

As described above, according to this embodiment, a key with an arrow for cursor movement and a shift key that gives a special meaning to a general data input key are pressed together in combination. By providing a mechanism that moves the cursor at high speed in the direction of the arrow marked on the cursor movement key that is being held down, the cursor can be moved to the desired location by the operator, even if it is an emergency on the display screen. The cursor can be moved quickly and instantly to the desired location even if it is far away from the target location, providing very user-friendly operability for the operator.

Effects of the Invention 'The key-powered device for moving a cursor of the present invention is separate from the key-powered device for inputting numbers and alpha vents into a computer and these keys; It has a shift key manual device and a display device for displaying the data and processing results inputted from these key manual devices, and furthermore, it moves a cursor on this display device to indicate the next position to be displayed. It has a human-powered key device with arrows pointing left, right, up and down as keys for moving the cursor, and by pressing the key with this arrow written on it, the cursor can be freely displayed in the direction of the arrow. In a device that can move the area, pressing this shift key manual device and the cursor movement key device with an arrow at the same time will be faster than pressing only the cursor movement key device with the arrow. By providing a mechanism that can move the cursor, the operator can instantly move the cursor to the desired position on the display screen, even if it is very far away, improving operability. It has become possible to improve the performance greatly, and its practical effects are great.
