JPS6375920A - Keyboard with variable key top size - Google Patents

Abstract

PURPOSE:To permit an optimum size to be selected by a user, to improve operability, and to reduce the fatigue of an operator, by providing a mechanism in which the size of the display area of a keyboard, and the size of a keytop of a key itself can be set arbitrarily. CONSTITUTION:The titled mechanism is constituted of a touch panel 1, a liquid crystal display element plane 2, and the keyboard 3, and the touch panel 1 detects the content of the key depressed corresponding (for example 4 and 5) to a keytop area being displayed on the liquid crystal display plane 2. The liquid crystal display plane 2 is formed by arranging the liquid crystal display elements as a dot pattern in a net shape, and an arbitrary dot can be displayed. Since the reference points of keyboard displaying areas 7, 7', and 7'', and the side length of a rectangle representing the keytop, are decided by the size of the keytop, and the keytop and the content of the key are arranged and displayed from the reference point, keyboard display display having an arbitrary size can be obtained on the keyboard display lane. In this way, since it is possible to select the keyboard of optimum size for a work, among several kinds of keyboards having different sizes, the operability can be improved, and the fatigue due to the work can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyboard, and particularly to a variable key top size keyboard that allows a user to change the key top size to a size convenient for use.

[Conventional technology]

Conventionally, as described in Japanese Unexamined Patent Application Publication No. 60-24619, there is a system that uses a liquid crystal display to display a playing board. However, the display area of the keys and the size of the key tops are fixed, and no consideration has been given to setting the optimum key size according to the user.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology does not take into account the size of the keyboard display area and the size of the key tops, which are determined by the hand size, finger length, and optimal range of hand movement, which vary depending on the individual user. First, there are problems such as decreased workability and increased fatigue.

SUMMARY OF THE INVENTION An object of the present invention is to provide a keyboard with variable key top size that allows a user to arbitrarily set the size of the keyboard display area and the size of the key tops, thereby obtaining a keyboard of an optimal size.

[Means for solving problems]

The above purpose is a keyboard consisting of a keyboard display surface with liquid crystal display elements arranged in a mesh pattern, a detection unit that detects the content of pressed keys corresponding to the key tops displayed on the keyboard, and a keyboard display and input control unit. This is achieved by the user setting the optimum key top size.

[Effect]

The keyboard display surface, which has liquid crystal display elements arranged in a mesh pattern, can display any figure in any position, and depending on the specified key top size, the reference point of the keyboard display area and the sides of the rectangle representing the key tops can be displayed. Since the length is determined and the key tops and key contents are arranged and displayed from the reference point, a keyboard display of any size can be obtained within the keyboard display surface.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In FIG. 1, the keyboard is composed of a touch panel 1°, a liquid crystal display element surface 2, and a keyboard body 3. The touch panel 1 detects the contents of the pressed keys corresponding to the key top areas displayed on the liquid crystal display surface 2 (for example, 4 and 5). The liquid crystal display surface 2 has liquid crystal display elements arranged in a mesh pattern in a dot pattern, and can display arbitrary dots. The keyboard main body 5 is equipped with a touch panel 1 and a liquid crystal display surface 2, and has a table on which key contents are displayed in a dot pattern, a management table with a keyboard display, and a touch panel 1.
It has software that controls the liquid crystal display screen 2. In FIG. 2, 3' is a view of the keyboard body 5 viewed from directly above, and keyboard boards 7, 7' and 7' having different display areas can be displayed. 6.6' and 6' indicate the origins of the keyboard display areas 7.7' and 7', respectively.

When the power is turned on, a keyboard of the size of the keyboard area 7 is displayed. Use this keyboard as the basic size and use the size change PF when you want to enlarge or reduce the keyboard and key top size.
By selecting and instructing the key 8 and size designation from the numeric keypad 9, the 7' or 7' keyboard can be displayed. Size changes can be specified at any time when the power is in C state.
Regardless of the size of the keyboard, the size of the characters that display the key contents is constant.

Next, the algorithm for displaying the keyboard will be explained with reference to FIGS. 5 and 4. FIG. 3 is a diagram for explaining the method of displaying the keyboard, and FIG. 4 is a flowchart showing the process of displaying the keyboard.

When the power is turned on, the software 12 that controls the display of the keyboard 19 extracts the characters of the key contents from the character generator 1o and generates the key contents dot pattern table 13. Next, the reference point 15 of the keyboard 19 and the length of the key top 1701 (the length of the side and the number of dots) 20 are determined based on the contents of the size specification parameter 11 (initial value when no specification is made). The management table 14 includes the contents 21 of each key to be displayed on the keyboard 19, and the relative position t! of the key top 170 reference point 16 from the keyboard reference point 15! i22, the length of one side of the key top 17, 2o, and the number of keys, 24, are stored. Ken board 19
After turning off all 0 dot patterns, set the control table, the previously determined single point 15 on the keyboard base, and 1 on the key top.
The length of the side is 20, j: the number of rekeys is 24, and the removal process is repeated. The key top reference point 16 is calculated from the relative position 22, the keyboard reference point 15, and the length 20 of one side of the key top (404). The dot pattern forming the key top 17 is turned on (410). Contents of each key to be displayed 21 and key content dot pattern table 1
0NK-j the dot pattern of the key contents from 5 (41
2).

The counter is incremented and the process is repeated until the number of keys reaches 24 (414, 416).

According to this embodiment, it is possible to select a grinding board of the optimum size for the work from among five types of grinding boards of different sizes, so that operability can be improved and fatigue caused by work can be reduced.

It goes without saying that the key arrangement can be freely changed by changing the key content dot pattern.

Further, although the present embodiment has been explained using a liquid crystal display button, the present invention is not particularly limited to this.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, in accordance with the case where the optimum movement distance of the finger differs depending on the user,
Since a keyboard of the optimal size for the user can be displayed on a single keyboard, this has the effect of improving operability and reducing fatigue.
