Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is applicable to computers, high-performance calculators, etc., which have a display device with a two-dimensional spread and a keyboard 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.

Conventional configuration and its problems In recent years, many human-powered devices have been produced and sold, but they all have left, right, up and down arrow keys when you need keys to move the cursor. This key moved the cursor in the direction of the arrow written on the pressed key.

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.

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 in the key-powered device 1 is pressed, the input board 3. The data is input to the microcomputer 2 via the memory 4, and the microcomputer 2 then issues a command to move the crane to the display device via the output port 5. However, in the above configuration, in addition to the normal data keys, keys with arrows for moving the cursor are required, which requires a large space especially in small-scale systems. In addition, from the viewpoint of operability, the user's hand has to be moved more frequently.

OBJECT OF THE INVENTION The present invention solves the above-mentioned problems of the conventional technology, and uses existing keys to move the cursor, which is absolutely necessary due to the original data, and has good operability. The object of the present invention is to provide a key-powered device for moving a cursor that can input the following information.

Structure of the Invention The present invention has a key-powered device for inputting numbers and alphabets into a computer, and a shift key-powered device for giving different meanings to these keys apart from these keys. These keys When displaying deltas and processing results manually input from a human-powered device on a display device, moving the cursor to indicate the next position to be displayed on this display device is done using the shift key and keys for inputting numbers. This is a manual key device for moving the cursor that has a mechanism for moving the cursor by pressing them simultaneously.This method allows the total number of keys to be reduced, which saves space, and also reduces functionality. Moreover, the operability can be improved.

DESCRIPTION OF THE EMBODIMENTS FIG. 3 is an external view of a key-powered device for a computer including a key-powered device for moving a cursor according to an embodiment of the present invention. FIG. 4 is a block diagram showing the configuration of the same 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 simultaneously presses the number key 8 and shift key 7 above the numeric keypad on which the number keys in the keypad 6 are lined up at 10%. . Then, when this key is pressed, the contacts of the switches inside each key open and close, and this causes the microcomputer 11 to input water as a potential difference. It is read through the memory 10. That is, according to the process shown in FIG. 5, the microcomputer 11 determines which key and shift key were pressed at the same time based on which signal line's potential has changed, and moves the cursor in the direction corresponding to each number. A command is issued via output port 12 to the Nice Play display to cause it to move.

In this example, the cursor moves in the direction in which the inserted numeric key is located when viewed from the center of the numeric keypad. Specifically, if the number 11 key and the shift key are pressed at the same time, the cursor moves toward the lower left of the display screen because the number 1 key is located at the lower left of the numeric keypad.

Hereinafter, the moving direction of each number key and cursor is "2" - down, r3j = lower right, r, 4J = left, "6" - right.

"7" = upper left, r8J' = upper, f'9J = upper right.

As described above, according to this embodiment, it is very easy for the operator to understand by directly correlating the position of the numeric key with the direction of movement of the cursor. Because it is located above the Shift key and above the Shift key, you can issue commands to move the cursor to any location without moving your hands, and in many cases, the operator does not have to worry about the Shift key or numeric keypad being displayed on the keyboard. You can freely press any key while looking at the screen without checking the characters on the screen, so you can move the cursor freely in any case without moving your eyes while looking at the screen. This can greatly improve operability.

Effects of the Invention The cursor movement key manual device of the present invention includes a key manual device for inputting numbers and alphabets into a computer, and a key device for inputting numbers and alphabets into a computer, and a key device for giving a different meaning to these keys apart from these keys. Shift key Human-powered device and these keys There is a display device for displaying data and processing results that are manually input from the human-powered device, and the shift key is used to move the cursor to indicate the next position to be displayed on this display device. By providing a mechanism for inputting numbers by pressing the keys simultaneously, the space required for the keyboard input device for human data input can be reduced and the number of parts required can be reduced. The cursor can be moved freely to the left, right, and even diagonally, and these can be done using the key combinations that are most commonly used by the operator, which greatly improves operability.The practical effects of this are: big.
