Abstract

PURPOSE:To obtain a data input device which has good operability and can decrease remarkably the time required for moving a cursor, by converting plural specific keys placed on a keyboard, to cursor moving keys. CONSTITUTION:In case of moving a cursor displaced in some area on a screen, to other area on the screen, first of all, plural specific keys placed on a keyboard are converted to cursor moving keys by depressing an exclusive key 34, and the cursor moving key whose state correspond to the area to which it is desired to move the cursor is depressed. As a result, from a multiplexer 32, information for showing a fact that these keys have been depressed simultaneously is sent to a microprocessor 40. Subsequently, by a cursor control program 41 contained in the microprocessor 40, a location data corresponding to the cursor moving key which has been depressed is read out of a character key location correspondence table, and based on it, the cursor on the screen is moved.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a data input device in an information processing device.

[Conventional technology]

Conventionally, data input devices have been provided with independent cursor movement keys for moving the cursor up, down, left and right, and movement has been performed using only these keys.

[Problem that the invention seeks to solve]

Cursor movement using the above-mentioned conventional up/down/left/right cursor movement keys is performed independently up/down/left/right, which results in extremely poor repeatability when moving the cursor in diagonal directions, which is commonly performed and involves a relatively long distance. The drawback is that it takes extra time, especially for those who are inexperienced.

Additionally, in order to relatively easily move the cursor, it may be possible to use dedicated cursor hardware such as a trackball, mouse, joystick, or stylus in the information processing device, but this generally has the disadvantage of being expensive. An object of the present invention is to provide a data input device that has good operability without using cursor-specific hardware and can significantly reduce the time required to move the cursor.

[Means for solving problems]

The configuration of the data input device of the present invention is such that the data input device has a keyboard, and includes a dedicated key for converting a plurality of specific keys into keys for moving a cursor; The present invention is characterized by comprising means for determining which input information of a plurality of specific keys corresponds to the input information and moving the cursor corresponding to the plurality of specific keys based on the information.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 shows the CR of a data input device which is an embodiment of the present invention.
2 is a front view of the screen portion of the T-display, which is composed of a CRT display main body 10 and a screen 11. FIG.

Figure 2 is an example of a keyboard layout with dedicated keys for the data input device shown in Figure 1. Character keys such as "Alphabet", "Number", and "Kana" keys,
Control keys such as ``RL''``rcAPs'', rsHIFTJ, rkana'', and ``G RP HJ keys, several function keys, keys for moving the cursor in four directions (up, down, left, and right), and ``numeric'' keys, etc. It consists of a numeric keypad.

FIG. 3 is a diagram of the electrical system shown in FIGS. 1 and 2, and includes the key matrix 31, dedicated key 34, CTRL key 35, CAPS key 36, . 5HIFT key 37, Kana key 38, and G
RP H key 39 connects power line 30 and multiplexer 3
Connected to 2.

Multiplexer 32 is connected to microprocessor 40 via data path line 33. The microprocessor 40 has a cursor movement control program 4.
1, and the cursor movement control program 40 has a character key/location correspondence table 42.

Microprocessor 40 is also connected to CRT display 43 via a data path line.

4th [2] is a flowchart showing the processing procedure of the cursor movement control program 41 in the block diagram of FIG. 52, a cursor movement process 53 to a specified location, a character input process 54, and an EXIT 55.

Next, the operation of this embodiment will be explained.

In FIG. 1, it is assumed that a cursor is displayed in any area on the screen 11, and that the cursor is moved to the upper right area a of the screen 11. First, special key 2 in Figure 2
When 0 is pressed, the key with diagonal lines becomes the cursor movement key, and in that state, the upper right a of screen 11 in Figure 1 is pressed.
Press the key 21 in FIG. 2 that corresponds to the area. In this case, the dedicated key 34 in FIG. 3 and the corresponding portion of the key 71 helix 31 in FIG. 3 corresponding to the key 21 in FIG. 2 are connected to the power supply line 30 and the multiplexer 32. Therefore, the multiplexer 32 outputs information indicating that the dedicated key 34 and the key 21 in FIG. 2 are pressed at the same time.
Next, the cursor movement control program 41 in the microprocessor 40 executes the sent key power 50 in FIG. Dedicated key judgment process 5 from information
1, it is determined that the dedicated key 34 in FIG. 3 has been used, and in FIG. 4, the location data corresponding to the key 21 in FIG. In FIG. 3, the character key/location correspondence table 42 is read out, and in FIG.
Information about cursor movement is sent to the display 43, and the first
In the figure, the cursor is moved to area a on the screen 11.

Similarly, if you want to move the cursor to area b on screen 11 in FIG. 1, press the dedicated key 20 in FIG.
By pressing the key 22, the same operation as above is performed and the cursor is moved to area b on the screen 11 in FIG.

In addition, by using the dedicated keys, you can increase the up/down/left/right movement steps of the cursor movement keys to any fixed multiple, or change the "2", "4", "6", and "8" keys on the numeric keypad to "
Down J, "Left", "Right", "Up" movement keys, and "1"
”, “3”, “7”, and “9” keys to “lower left” and “lower right”
, "Top left" and "Top right" movement keys respectively, it is possible to realize a data input device with better operability. Pointing to the position can also be easily performed.

〔Effect of the invention〕

As explained above, the present invention significantly reduces the time required to move the cursor by using a dedicated key and pressing the key corresponding to the area to which the cursor is to be moved, thereby instantly moving the cursor close to the target area. The effect is that it can be done.
