Abstract

PURPOSE:To perform high-speed key input processing, by providing key switches which have programmable patterned display elements internally and making it possible to see display contents from the external. CONSTITUTION:A key switch on a keyboard is used to display of first Kana (Japanese syllabary) characters. When a key of a switch SW2 is depressed, the display of Kana characters is changed to the display of a Kanji (Chinese character) beginning with the sound of the depressed Kana key. When a desired Kanji is found, a key switch SW3 is depressed to input Kanji. When Kanji is inputted, the display is changed to the display of Kana characters to prepare for the next Kanji input. By using this keyboard, the number of characters is increased easily if added characters have programmable pattern constitutions, and high-speed key input processing is possible.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a key switch found in a keyboard.
In particular, it relates to multi-functionality of key switches.

Generally, the function of a key switch found in a keyboard is often used as a single function of an indication written on the top or side of the key switch by preparation or printing.

However, there are times when you want to use Jin's key switch for multiple functions.

Conventionally, in the empty space of the key switch, a display for performing other functions could be placed, or a whole card with the key switch part cut off, fitted onto the key switch, and a key switch on the card. By putting the function into the part or upper part of the car and replacing it, it was possible to increase the number of key switches.

For the former, there are functional limitations, and for the iron, when many cards are required, it takes time to replace the cards, and the key switch itself requires little human effort. There was an inconvenient field.

The present invention has been devised to solve the above-mentioned drawbacks.

That is, the present invention is characterized in that a key switch is provided with a programmable patterned display element inside the key switch so that the displayed content can be seen from the outside. The display tube F9r (
11-To make the key switch multi-functional by 7L functions depending on the function.

Regarding the pattern structure, for example, if you want to have alphanumeric characters, you can place a 5x7 matrix of light-emitting elements in the key switch, and if you want to have kanji characters, you can use a 16x16 or 24x24 matrix. All you need to do is set the display fL in the matrix display key switch. Furthermore, Naogan 2
By using the Kyokushu's front board, it is possible to express the function of a key switch graphically.

When using the key switch of the present invention for multiple functions, the display contents of the key switch can be changed by a program, so there are no functional limitations as mentioned above, and there is no need for the physical operation of exchanging cards, making it possible to increase the number of functions. In contrast, high-speed processing is possible.

As an embodiment of the present invention, a kanji input method for Nippon Kei Ward Glossary Nanatsusa will be explained.

In the conventional method, as shown in Fig. 1, the key switch section (S
Insert the kanji into the part corresponding to the bottom of each key switch on the panel (position Q) with one part of WI) removed,
Close those panels from above the key switch. There - Jinjin no Tsuki 7. For example, if you want to find the kanji 1, 1, flip the panel and look for the kanji 1, 1, and when you find it, press the key switch (in this case (SWI)) 2 above it.

Now you can input the characters 1, 1, and 11. With this method, in addition to the key switch key □tC7'C7 turn operation, the operation of flipping the panel t is included.
There was a drawback that inputting a single character was slow.

Another disadvantage is that as the number of characters increases, the number of panels increases, making handling difficult.

This is an application example of a key chain (a series of key switches) using the key switch of the present invention, which may have omitted the operation of flipping the panel gold. As a manual method for writing kanji, we use Jl Hosuke to transform kana into kanji. First, kana characters are displayed as shown in Figure 2. Now, if you want to input the characters 1, 1, 1, press the SW2 1, power 1 key switch in Figure 2. Then, what was previously displayed in kana characters will be changed to display examples of kanji characters starting with 1riki 1, as shown in the 3 diagrams of ka.

Then, search for the characters 1, 1, 1, and if you find one, hit the key switch SW3 in Figure 3, and the kanji will be input. When kanji are input, the display changes to kana characters as shown in Figure 2, and preparations are made for the next kanji input. However, changes in character display and character discrimination functions shall be performed by a control system installed outside of this keyboard.

Even if the number of characters per character increases by using a non-keyboard, if the pattern structure allows the increased characters to be programmed, the number can be increased without any problems, and there is no physical action such as flipping the panel, so all Since key switches can be processed by tapping ink, high-speed manual key processing is possible.
