Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a communication keyboard used as an input means for computers, word processors, etc.

(B) Conventional technology Traditionally, keyboards for computers, word processors, etc. have arranged all kinds of input keys because the number of characters, numbers, symbols, etc. (hereinafter referred to as characters) that can be entered is enormous. Instead, each input key is also used to input characters such as river ladders, and the mode selection key selects one of them.

However, since there is a limit to the number of dual-use slots for these types of gear, there are only a few types to choose from. ! It's hard to see because two numbers, etc. are displayed, and it's hard to tell which mode is currently selected or which mode to select next, and it's hard to be sure if you're inputting correctly. Since the operator must look at the display on the cathode ray tube each time he or she reads e, the operator has to look at the cathode ray tube and the keyboard alternately, making operation 1.1 extremely difficult.

(c) Problems to be Solved by the Invention The purpose of the invention is to improve the above-mentioned drawbacks of the conventional system. , you can perform input operations while looking only at the keyboard, and
To provide a communication keyboard with an infinite variety of display contents.

(d) Embodiment An embodiment in which a computer keyboard of the present invention is connected to a word processor will be described with reference to the drawings.

A word processor 2 equipped with a Braun/Kankan display device 1 is connected to a ComiUnicacon keyboard 3.

Arranged on the communication keyboard 3 are a type of communication key 4 that detects pressing force and performs switching, and a normal bush type key 5.

As shown in FIG. 2, the communication key 4 is provided on the surface of a glass plate 4b provided on the liquid crystal display plate 4a.
A large number (for example, 101,130 rows) of minute pressure-sensitive transistors 4C that detect pressure and perform switching are arranged, and the surface thereof is made of a flexible plastic film 4.
dT: ff is one piece.

The liquid crystal display 11i4a includes an array of pressure sensitive transistors 4.
Each pressure sensitive transistor 4C is divided into the same number as the number of transistors C.
There is a one-to-one correspondence with the sections of the liquid crystal display board 4a located on the back side. Note that the boundaries of the sections do not need to be displayed.

Information such as commands sent from the word processor 2 is displayed independently in the sections of the liquid crystal display board 71a corresponding to the respective pressure sensitive transistors 4C.

The size of the 8 pressure sensitive transistor 4C is extremely small (for example, 1 mm or less), and therefore, although it is located almost at the center of the corresponding section, it does not substantially control the display content of that section. can be identified.

By lightly pressing one of the pressure-sensitive transistors 4C with a finger or the like, No. 13 corresponding to the display content or screen displayed in the corresponding section of the liquid crystal display board 40 is input into the word processor 2.

The displayed content can be anything that the space allows, such as kanji, alphabets, numbers, kanji, simple sentences combining these, etc., and can be displayed in overwhelming size.

In addition, the number of characters of displayed information, commands, etc. This can be done by pressing the pressure transistor IC.

For single-layer use, if you select, for example, the "Hiragana" mode with the Bush style layer 5, a hiragana character will be displayed in each section of the liquid crystal display board 4a, and the character you wish to input, such as "A", will be displayed.
"A" is input by pressing the little finger on the section (the pressure-sensitive transistor 4C) in which "A" is displayed and suppressing it for a while.

Next, select a different 811-1 card, for example "English lowercase letter" C-card 3 selections U! ! Then, lowercase letters of the alphabet are displayed in each section of the liquid crystal display board 4a, and the desired character can be entered in the same way by pressing the section where the desired character is displayed.

Incidentally, without providing the pushbutton type keys 5, all input operations including mode/option selections may be performed only with the community key 4.

FIG. 3 shows another embodiment of the communication key.

A large number of transparent or translucent conductive patterns 4C are formed at equal intervals on the upper surface of the temporary glass 4b and the lower surface of the flexible transparent plastic film 4d using known means such as thin coating. .

This crow) 4b and plastic film 4d are provided with flexibility between them) or translucent conductive rubber 4
The two conductive patterns 40 are laminated so as to be perpendicular to the conductive pattern 4e, and each intersection of the conductive ratio pattern 4e appears, and the pressure-sensitive swing 1 is formed in Ij4. ).

The other combinations and their functions are exactly the same as in the embodiment described above.

, In the case of F-registration, the word processor controls the selection of f4'tb', d', and f4'tb.
By having a built-in roller and presetting it according to the No. 13 processing mode of the connected computer or word processor, you can make it possible for the communication keyboard to process mode fixed translations and simple commands by itself.
It can reduce the load on the Conbuque side and is extremely effective when used in small personal computers and the like. In case of
If the memory is non-volatile, such as magnetic bubble memory, there is no risk that preset programs will be lost even if the power is turned off.

Further, in the above embodiment, a liquid crystal display panel is used as a display device disposed below the pressure-sensitive element, but the display device is not limited to this. It is also possible to use well-known elements, devices, etc. that can change the displayed content using an electronic circuit, such as a large number of plasma displays arranged in large numbers.

Sensitive elements include not only pressure-sensitive transistors, but also piezoelectric elements, capacitive pressure capacitors, etc.
Well-known devices such as pressure-sensitive diodes can be used as appropriate. Further, the pressure sensitive elements may be formed directly on the surface of the display wave r instead of arranging them on a separate glass plate as in the above embodiment.

In short, the pressure-sensitive element only needs to be transparent, translucent, or extremely small so that the operator can substantially recognize the display content displayed thereunder.

(G) As described in detail, the communication keyboard of the present invention has a large number of pressure sensing blocks on the surface of the liquid crystal display board, so that the displayed contents of the display board can be substantially changed from one to the other. By using the Press V Sensitivity keys, which are arranged in an intuitive manner, commands and information from a connected computer, etc. can be displayed on the keyboard. The operability is good because you can do it.

In addition, since the display content is controlled by an electronic circuit, the amount of information that can be displayed on the back side of each compartment is infinitely large, and requires fewer input keys (pressure-sensitive elements) than conventional devices. By far, the input of 51 classes is equivalent to 11).
