Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a display device 1 for a data processing system.
Keyboard operation method for controlling the cursor position with 8 keys (up to 1% when operating the keyboard).

It is possible to move the cursor with both hands of the operator at the home position (keyboard method C2).

[Technology background]

Terminal devices, word processors, office computers, etc.

When using a data processing device equipped with a display/keyboard, data can be entered or corrected at designated locations on the display screen.

In order to delete items, the cursor is frequently moved up and down and left and right.

Conventionally, various methods have been used to move the cursor, including special keys, joysticks, trackballs, and mice, but all of these methods require you to move your hand away from the home position on the keyboard. must be operated. Therefore, there is a problem in that the speed of manual keystroke decreases, the position becomes unstable, and the number of manual keystroke errors increases.

[Object and structure of the invention]

An object of the present invention is to provide a keyboard mechanism that allows 8 cursor movements while maintaining the keyboard's home position (both hands).
Make the keyboard body movable.

It functions as an input means such as a joystick or trackball, and can generate cursor control signals, thereby enabling efficient manual key operation.

The configuration of the present invention includes a keyboard body configured to be movable on nine display devices from its mouth, and a means for detecting displacement of the keyboard body in a predetermined direction C2, and a means for detecting displacement of the keyboard body. The output of the keyboard is used as a cursor movement control input signal to move the keyboard body in a predetermined direction (second, to perform cursor operation).

[Embodiments of the invention]

The present invention will be specifically explained below using nine examples.

Figures 1 (α) and (AL (C) are schematic views of one embodiment of the present invention, in which (a) is a top view of the keyboard, and (b) is a top view of the keyboard.
) shows a front view, and (C) shows a side view. In the figure, 1 is the keyboard.

1a is a key, 1i is a cover plate, 2 is a stand, 3 is a sensor, 4
is an actuator. In addition, if keyboard 1 is
(9) For bistable support, it is necessary to provide 9 elastic support members at the four corners of the keyboard, but one is omitted in this figure for ease of viewing. Also, even if there are two displays, the conventional It is excluded from Figure 1 because there is no need to change the mechanism.

The actuator 4 is attached to the center of the keyboard 1, and the keyboard 1 is swung around the actuator 4 in the direction in which you want to move the cursor (-back and forth and left and right on the keyboard surface). (h) shows the tilted state after being swung back and forth, and Fig. 2 (
C) I (d> indicates the left and right ('''-tilted state), respectively.

If the operator wants to move the cursor, he/she should keep both hands or a few fingers such as the thumb fixed on a predetermined key at the home position, and use other fingers or the palm of the hand to move the cursor on the cover plate. Press the appropriate position. For example, to move the cursor to the right, press C2 on the right side of the keyboard.

If Keiji wants to move the cursor downward, he can press down on the front side of the keyboard. With this C2, the keyboard 1 can be selectively swung forward, backward, left, or right.However, when pressing the keyboard, there is a risk that one of the keys C will be stuck and activated accidentally. , known double keystroke prevention mechanisms can be used to prioritize cursor control signals.

The sensor 3 converts the movement of the actuator, which tilts in response to the rocking of the keyboard 1, into a signal that controls the vertical and horizontal movement directions of the cursor, and in principle has a mechanism similar to that of a known joystick. For example, arbitrary movements of the actuator 4 are often divided into four directions (two directions) on orthogonal coordinate axes using a gimbal, and then extracted as control signals by four sensors corresponding to each axis direction.

The second is a limit switch using mechanical contacts, or a proximity switch 3α of a magnetic, optical sensor or other type commonly used in this field, as shown in FIG.
, 3A 3c, 3d around the actuator 4,
Those arranged in four axial directions can be used.

FIG. 4 shows another embodiment in which the sensors are arranged around the keyboard periphery (bidispersed). FIG. 4 (α) is a bottom view of the keyboard, and (h) is a front view. In the figure, 1 Keyboard, 2 is stand s 5”s 5A 5C*
5 d is a sensor in the direction of the valley coordinate axis, and 9 mechanical contacts or piezoelectric type switches are used. Further, 6 is an elastic support member for stably holding the keyboard 1 in a predetermined position C on the base 2.
The operations are performed in the same manner as in the embodiment shown in the figure, and the keyboard 1 is selectively pressed down on the front, back, left, and right sides of the keyboard 1 and tilted (secondarily, one of the corresponding sensors 5a to 5d is activated).

FIG. 5 shows another embodiment of the present invention (instead of rocking the keyboard as in the embodiment described above).

By moving the keyboard forward, backward, left and right.

It generates cursor control signals.

Figure 5 (-) is a top view, (b) is a front view, and 1 in 9 figures.
is a keyboard, 7 is a stand, 8 is a recess provided on the upper surface of the stand 7 with a small gap so that the keyboard 1 can be stored, 9a, 9A, 9c, 9d are sensors.

10 is an elastic support member that holds the keyboard 1;

11 indicates a caster.

The keyboard 1 is inserted into the recess 8 (with two or four elastic support members 1
0 and is held in a neutral position. When a force is applied to the keyboard 1 along its 9 planes in a desired direction, front, back, left, or right, the keyboard 1 moves a certain distance in that direction on the base 2.

Any one of the sensors 9α to 9d in the movement direction C can be activated.

This makes it possible to control cursor movement by applying a slight lateral force to the keyboard while keeping the keyboard in the Baum position with both hands, by activating arbitrary sensors in the front, back, left, and right directions.

Note that the means for detecting the rocking or movement of the keyboard is not limited to the example described above (but is not limited to one).

Many variations are possible using known techniques. For example, in the embodiment shown in FIG. It is also possible to adopt a method of detecting the movement of.

〔Effect of the invention〕

According to the present invention C2, the cursor operation can always be performed with both hands on the home position (-), so the data It is possible to improve the reliability of data by increasing the input speed and reducing the occurrence of erroneous key operations.
