Abstract

PURPOSE:To accelerate the input speed of data, by providing a cursor moving shift key which is depressed with a character key, and generates a cursor moving signal, in the neighborhood of the character key. CONSTITUTION:In a keyboard device, two pairs of cursor moving shift keys 11 are provided at the both sides of a space key 13, and also, the character key 20 is arranged so that fewer movement of hands is required, and a moving direction is easy to recognize. And when the character key and the shift key 11 are depressed simultaneously, the cursor moving signal having a prescribed direction is generated by a shift means 21. In this way, by arranging the cursor moving shift key 11 in the neighborhood of a JIS arranging part 1, it is possible to save the movement of the hands in an operation is which the character key 20 and the shift key 11 are depressed, compared with the one in which the character key 20 is depressed in advance.

Description

[Detailed Description of the Invention] [Summary] The present invention provides a keyboard device that is provided with a shift key that shifts the output signal of a character key, and that, when pressed together with a predetermined character key, generates a cursor movement signal in a predetermined direction. .

[Industrial application field]

The present invention relates to a keyboard device that facilitates cursor movement on a display screen.

A keyboard device is equipped with a cursor movement key for moving a cursor on the display screen in addition to a key part (hereinafter referred to as the JIS arrangement part) in which character keys etc. are arranged, but the cursor movement keys are usually located away from the JIS arrangement part. Since the keys are placed at different locations, there is a problem in that the movement of the hands becomes large when operating the keys.There is a need for a keyboard device that solves this problem.

[Traditional technique 1 trick] A conventional keyboard device will be explained with reference to FIG.

FIG. 3 (Al is a diagram showing an example of key arrangement, 1 is a JIS arrangement section in which character keys etc. are arranged based on JIS, 2 is a cursor movement key.

The cursor movement keys 2 are composed of four sets of keys that move a cursor displayed on a screen (not shown) up, down, left, and right, respectively.This allows operations such as moving the cursor and inputting characters at that position. It will be done.

FIG. 3 (bl) is a block diagram of a conventional keyboard device, in which a press signal of a cursor movement key 2 is encoded and input to the main body of the device, and increments a cursor counter (not shown) that controls the cursor position.

Note that the 5HFT key 3 is a shift key that shifts the output signal of the character key 4, such as shifting from uppercase letters to lowercase letters.

[Problem that the invention seeks to solve]

As in the above arrangement example, the cursor movement keys are arranged at a position away from the JIS arrangement section, and there is a problem in that the movement of the key operator becomes large.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a keyboard device that reduces hand movement and improves operability.

[Means for solving problems]

For the above purpose, the keyboard device of the present invention includes a shift key (11) for moving a cursor that is pressed together with a character key to shift the output signal of the character key, as shown in FIG. , character keys (20
), and a shift means (21) that generates a cursor movement signal in a predetermined direction when the character key and the shift key are pressed simultaneously.

[Effect]

A shift key 11 (hereinafter referred to as a cursor movement shift key to distinguish it from the conventional shift key 5HFT) is provided to shift the output signal of a character key, and character keys ■, ■, ■, ■ are set corresponding to the cursor movement direction. When pressed together, a cursor movement signal in a predetermined direction is generated and output to the main body of the device.

If the shift key 11 for moving the cursor is arranged near the JIS arrangement section, the operation of pressing the character key and the shift key 11 for moving the cursor can reduce hand movement compared to the previous character key operation.

Note that this cursor moving means is provided on a keyboard device together with conventional cursor moving keys.

〔Example〕

An embodiment of the present invention will be described with reference to FIG.

FIG. 2 (fa) is a key arrangement diagram of the embodiment, FIG. 2 (g)) is a block diagram of the keyboard device of the embodiment, and FIG.

In FIG. 2(a), the shift keys 11 for moving the cursor are arranged 2flJl on both sides of the space key 13, and the character keys 20 [■, ■, ■ , ■].

The arrow on the illustrated key indicates the character key at that position (Fig. 3 (a)
This shows the direction of movement by pressing the rJJ key.
Move rightward Q “F” key Move leftward ｽ rTJ rUJ key Move upward ? rVJ r
NJ key downward movement corresponds to 8.

FIG. 2 (bl indicates the cursor movement signal generation means in one direction (
The push signals of the rJJ key 14 and the shift key 11 for cursor movement are ANDed by an AND gate 17 to generate a rightward cursor movement signal 50, which is then applied to the cursor movement key by an OR gate 18. A cursor movement signal (right) 52 is outputted by ORing with a cursor movement signal 51 based on 2.

Note that the output of the character signal is performed by AND gates 15 and 16.
prohibited by

FIG. 2 (c+ is a diagram showing another embodiment, (1)
The character key group is divided into four to make it easier to press the character keys, and cursor movement signals in the same direction are ORed and output.

In (2), a character key is provided to move part of the arrangement in (1) to a specified position on the screen, and the illustrated arrow is -1 line, 1st digit (origin of the screen) 1 Last line, last digit 7 Last digit of the 1st line ← 1st digit of that line → Last digit of that line ♂ Represents the 1st digit of the last line, and the cursor counter on the device is set to the above position by the cursor movement signal output from this character key. .

As described above (the output cursor movement signal is shown in Figure 2 (
As shown in b), the cursor counter 21 is
to move the cursor 22 in a predetermined direction.

As described above, by providing a shift key that generates a cursor movement signal by shifting the output signal of a character key near the JIS arrangement section, it is possible to move the cursor without moving the hand.

Although the above description is based on the JIS arrangement, the present invention is not particularly limited to the JIS arrangement.

〔Effect of the invention〕

The present invention provides a shift key for cursor movement, which is pressed together with a character key to generate a cursor movement signal, in the vicinity of the character key, so that the hand movement distance can be reduced compared to conventional cursor movement keys. The effect of improving operability, such as increasing data input speed and reducing fatigue, is extremely large.
