Abstract

PURPOSE:To adjust the arrangement positions of respective key tops to the intervals of the fingers of a user by detecting the positions of the fingers of the key tops on a board, rearranging the positions of the key tops and stopping rearrangement in a key top contact detection part. CONSTITUTION:While the fingers are detached from the key tops more than a specified time, the coordinate value in vertical and horizontal directions for all the finger tips of both hands are detected from a position detection part for finger 1, and arrangement data are continued to be transmitted. When at least one finger is brought into contact with the key top, it is noticed to the control part 2 detected by a key top contact detection part 3. A key top rearrangement part 4 adjusts the key tops 6 of home positions to the positions of all the fingers of both hands, which have received from the position detection part of fingers at that point via the control part 2, rearranges the other key tops in accordance with the arranging intervals of the key tops of the home positions and fixes the arranging relation of all the key tops. Thus, the arranging relation relation of the adjacent key tops is decided by the intervals of the fingers.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a keyboard device.

[Conventional technology]

Conventionally, this type of keyboard device (generally called a keyboard) has alphanumeric keys and keys on the keyboard as shown in Figure 3.
Special symbol keys, katakana keys, function keys ・
Various key tops such as numeric keypad, spur, spur, etc. were arranged in fixed positions.

[Problem to be solved by the invention]

In the conventional keyboard device described above, the arrangement positions of the various key tops are fixed, so if the distance between adjacent key tops is smaller than the distance between the user's fingers and the thickness of the fingers, multiple keys may be accidentally pressed at once. The drawback is that you have to press the key tops, or if the keys are large, you have to use them with your fingers spread far apart. In addition, when performing a blind touch, it is generally assumed that the fingers of both hands are placed on the key top 6 at the home position, and the keys are pressed without directly checking each key top with the naked eye. If you repeatedly press key tops that are located far away from the home position, it will become difficult to know where the home position is. The disadvantage is that you have to touch the buttons in order to find the home position.

An object of the present invention is to provide a keyboard device that solves the above problems.

[Differences between the invention and the prior art]

The present invention differs from the conventional keyboard device described above in that the arrangement position of each key top on the keyboard can be moved, so that the arrangement position of the key top can be automatically adjusted according to the position of the fingertip.

[Means to solve the problem]

In order to achieve the above object, the keyboard device according to the present invention includes a position detection unit that detects the position of a finger necessary for rearranging the key tops on the keyboard, and a key top rearrangement unit that rearranges the positions of the key tops. , a keytop contact detection section that stops the rearrangement of the key dogs, and a control section that receives outputs from the position detection section and the keytop contact detection section and issues a drive command for the keytop rearrangement section. .

〔Example〕 Embodiments of the present invention will be described below with reference to the drawings.

(Example 1) FIG. 1 is a block diagram showing the basic configuration of the present invention.

In the figure, the basic configuration of the present invention includes a position detection unit 1 that detects the position of a finger necessary to rearrange the key tops on the keyboard, and a key top rearrangement unit 4 that rearranges the positions of the key tops. , a keytop contact detection section 3 that stops the rearrangement of the keytops, and a control section 2 that receives the outputs from the position detection section 1 and the keytop contact detection section 3 and issues a drive command for the keytop rearrangement section 4. have

FIG. 2 is a perspective view showing a first embodiment embodying the basic configuration of the present invention.

In the figure, a keyboard device main body 5 incorporates a key dog re-arranging unit 4 that moves the key tops of the keyboard in the horizontal and vertical directions to rearrange the key dogs.
The key tops moved by the key top rearrangement unit 4 are
The front surface of the keyboard device main body 5 is shown below the arrangement shown in the figure. FIG. 3 is a diagram showing the key top layout of the QWERTY keyboard. In the case of this QWERTY array, A, S
.

The nine key tops D, F, J, ni, L, and space bar are key tops 6 at the home position. A
, S, D, and F key tops 6 are the pinky fingers of the left hand, respectively.
These are the home positions of the ring finger and the middle finger, and the key dogs 6 of J, N, L, ; are the home positions of the index finger, middle finger, ring finger, and little finger of the right hand, respectively. The key top 6 of the space bar is the home position of the thumbs of both hands.

Further, on the front surface of the keyboard device body 5, position detection units 1, 1 are arranged in the vertical and horizontal directions in order to detect the vertical and horizontal coordinate values of all the fingertips of both hands. hand#! i, a key top contact detection section 3 is provided, and a control section 2 is built into the main body 5 of the device.

In this embodiment, first, the finger position detection unit 1゜1 detects the vertical and horizontal coordinate values of all fingertips of both hands only while the finger is lifted off the key top for a certain period of time or longer. Continuing to send placement data to the control unit 2 Next, when at least one fingertip touches the key dog, the key top contact detection unit 3 detects this and notifies the control unit 2.

The key top re-arranging unit 4 moves the key tops 6 of the home position to the positions of all the fingers of both hands that have been picked up from the finger position detection unit 1 via the control unit 2, and then adjusts the key tops 6 of the home position to the positions of all the fingers of both hands. The top is also rearranged according to the arrangement interval of the key tops at the home position, and the arrangement positions of all the key tops are fixed.

Thereby, the spacing between adjacent key tops is determined according to the spacing between fingers. In addition, when you are working on alternately hitting key tops near the home position and key tops far from the home position, if you keep your finger above the key top for a certain period of time, you can visually check the key dog. Even if you don't do this, the key tops in the Baum position are automatically relocated directly under each finger, so you can automatically adjust the placement of each key top at any time while typing on the keyboard.

(Example 2) FIG. 4 is an overall view showing a second embodiment of the present invention.

In this embodiment, a key top rearrangement section 7 displays the key top positions on a liquid crystal display panel on the entire upper surface of the keyboard device.
Since all key tops can be displayed in any position, when adjusting the placement position of Keytra 1, you can simply display the key tops in the new position without actually moving the key tops. The advantage is that it can be done with

〔Effect of the invention〕

As explained above, the present invention has the advantage that by being able to move the arrangement position of each key top on the keyboard, it can be automatically adjusted to the position of the fingertip, and the spacing between each key top can be adjusted to the spacing between the user's fingers. There is. Furthermore, by automatically adjusting the placement position of each key top at any time during keyboard typing, it is possible to perform tasks such as alternately hitting key tops near the home position and key tops located away from the home position. This has the effect of allowing continuous blind touch operations without the need to visually check the key tops.
