JPS6165328A - Communication keyboard - Google Patents

Abstract

PURPOSE:To perform input operation over a look at only a keyboard and to improve operability by displaying commands, information, etc., from a computer on input keys on the keyboard. CONSTITUTION:A touch type communication key 4 and normal push type keys 5 are arrayed on the communication keyboard 3. The communication key 4 is formed by forming many rectangular transparent or translucent touch sensitive electrodes 4c on the surface of a glass plate 4b provided on a liquid crystal display plate 4a. Information such as commands sent from a word processor 2 are displayed independently at respective parts of the liquid crystal display plates 4a at the reverse side of respective sections of the touch sensitive electrodes 4c, and an electrode 4c is touched to input its display contents or a signal corresponding to it to the word processor 2.

Description

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

(b) Conventional technology Conventional,] Combi coater warp []1? The Tsuribou keyboard has a huge number of types of characters, numbers, notes, etc. (hereinafter referred to as characters) that can be input, so instead of arranging all types of input keys, each The input "1"- is also used to input characters such as seconds, and is used as a mode selection key to select one of the following.

However, in such a case, there are only a limited number of types that can be used in combination, so there are only a few types to choose from. , Which t-card is currently selected?
Next, what should I do? It's hard to understand what's going on, and each time I have to check the display on the cathode ray tube to see if I've entered it correctly. Therefore, the operator had to look at the cathode ray tube and the keyboard alternately, resulting in extremely poor operation.

(C) Problems to be Solved by the Invention Objective 1 of the invention: To improve the shortcomings of the conventional devices described in J, L, and the like, messages from a connected computer etc. can be transferred to the input key of the keyboard. It is possible to perform input operations while looking at the displayed keyboard ( ), and what's more, the Comi-Uni-Cage Con Keyboard 1: has an infinite variety of display contents.

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

To the word processor 2 that designed the cathode ray tube display device 1'
:l The communication keyboard 3 is connected.

Communication
Formula keys 5 are arranged.

As shown in FIG. 2, the computer 1 knee 4 has a large number of rectangular transparent or "1' transparent touch-sensitive electrodes 4G installed on the surface of the liquid crystal display panel 4a and the glass panel 4b. (for example, 10 rows and 30 columns).

Information such as commands sent from the word processor 2 is displayed independently on each part of the liquid crystal display panel 4a located on the back side of each section of the touch-sensitive electrode 4C.

If you touch any section of the touch-sensitive electrode/IC with your finger, touch the LCD panel 4 on the back side of that section.
A signal corresponding to the display content displayed in part a or -() is input to the word processor 2.

The display contents are kanji, alphabetical characters 1~, numbers, symbols, (
Any combination of these can be displayed in any size as long as the space allows, such as a simple sentence.

Also, if the displayed information, instructions, etc. have a large number of characters,
It is displayed across multiple partitions, and input operations can display information,
Is the tap sensitive live electric in the part where commands etc. are displayed?
C. Touch the throat area (can do 6 things).

When using it, if you select, for example, "Hiragana" ■-do using the Bussico style ↑-5, hiragana will be displayed on the back side of each section, and you can place your finger in the section where the character you want to input, for example "A", is displayed. By touching it, "a" is input.

Next, if you select a different mode, for example the ``lowercase letter'' mode, the lowercase letter to Alphabella 1 will be displayed on the back side of each section, and you can also enter it by touching the section where the character you want to input is displayed. can be entered.

It should be noted that all input operations, including mode selection, may be performed using only the communication key 4 without providing the pushbutton type 1 key 5.

In the above embodiment, mode selection control is performed by the word processor 1 on the side, but the communication-1-board has a built-in memory and a dedicated controller []=-, and is connected to the word processor 1. Computers and Wordpress [1t
? By presetting according to the type of signal processing of the controller, the load on the computer can be reduced by allowing the keyboard to process simple commands on its own. This is effective when used in small personal computers, etc.

In this case, if the memory is nonvolatile, such as a magnetic bubble memory, there is no risk that the preset program will be lost even if the power is turned off.

Further, in the above embodiment, a liquid crystal display board is used as a display device disposed under the touch-sensitive electrode, but the display device is not limited to this. It is also possible to use well-known elements, devices, etc. whose display contents can be changed by an electronic circuit, such as a plurality of display elements or a plasma display.

0) As described in detail of the invention, this invention has been described in detail.
- The board is equipped with touch-sensitive keys, which are equipped with transparent or translucent tap-sensitive electrodes partitioned into many sections on the surface of the liquid crystal display panel. The display contents can be displayed on the top of the screen, and the displayed contents can be inputted while still being a child, so the operability is extremely good.

In addition, since the display content is controlled by electronic circuitry, the types of information that can be displayed on the back side of each section are infinitely greater, and the number of types of information that can be displayed on the back side of each section is infinitely greater. This allows a wide variety of inputs to be made.
