Description

Double-key pocket computer key board

The utility model is a kind of pair of pocket music computer keyboard of key, relates to microcomputer computer and field of components thereof.

The at present general used input keyboard of PC is directly diverted from one use to another from English machinery typewriter.Some basic characteristics of machinery typewriter comprise all function keys and the distribution of character, all do not have what variation.So strictly speaking, people also are not that the literal input of computer designed special keyboard so far.The major technique feature of computer also can not embody on mechanical keyboard fully.Right inclined is taked in key position arrangement such as QWERTY keyboard, is the form of intactly having followed mechanical keyboard.This form has the custom basis for the people who is familiar with English machinery typewriter, but for the Chinese that are unfamiliar with it, has not just had necessity.On the QWERTY keyboard 48 enter keies are arranged generally now, except 26 letter keys and 10 numerical keys, also have 12 symbolic keys.Input is absolutely necessary for literal to have only 5 punctuation keys in these symbolic keys.Other special symbol keys then do not have anything to use, and general computer is not arranged input function yet, and as many as is useless key.Letter on the QWERTY keyboard arranges neither according to alphabet, neither arrange according to usage frequency, but for some special considerations of physical construction aspect.The consideration of only some use aspect, extremely low as letter " Z " occurrence frequency in English, so the position on keyboard is also more inclined to one side than punctuate, the situation of this and Chinese is also very inapplicable.Because QWERTY keyboard has adopted the inclined arrangement, wait the miniaturization measure to cause the difficulty that is difficult to overcome with folding also for the decomposition of keyboard.

The purpose of this utility model is, at the shortcomings and deficiencies of QWERTY keyboard character layout when input is Chinese, and can not portability and the physical construction defective of miniaturization, design a kind of specially for importing the miniature keyboard that Chinese is equipped with and the thorough character layout of Chinesizing.Chinese keyboard after the reform is similar substantially to QWERTY keyboard in keyboard layout, so also can realize without difficulty on the civilian hereinto keyboard of the basic function of QWERTY keyboard.But compactness is more arranged by the keyboard layout after the reform, and character Chinesizes fully.Symmetrical keyboard can decompose, fold, and is easy to miniaturization, portability, and is easier to operation.It is microminiaturized to greatest extent that the design of " screen two keys " then makes input tool accomplish.

The utility model is realized by following technical scheme: forming of the pocket Chinese Computer keyboard 1 of two keys is a panel and two key knobs, i.e. " screen two keys ".Demonstrate a dibit Chinese projected keyboard on the panel, be divided into symmetrical two parts, the key position of every part respectively is the five-element's five row, forms the square formation of 25 key positions (actual is 23 key positions), and is neat and succinct.Respectively there is a key knob both sides of panel, can carry out the plane and move, a contact be arranged below the key knob, between 23 contacts that are located on the chassis, move, the circle battle array that is designed to of each contact, chassis distributes, and therefrom the displacement of mind-set all directions is full and uniform.Below the key knob on each contact of circle battle array and the panel each key position of shown character square formation form corresponding relation accurately.Each contact is by the pilot lamp of each key position of circuit UNICOM on the key knob chassis.When certain contact on key knob contact and the chassis when touching, corresponding key position is promptly illuminated by background light in the character square formation on the panel, forms transportable cursor.Press the key knob this moment, and signal circuit is switched on, and key position pilot lamp dodges by force, and character shown on the panel is promptly imported by signal line.Music encoding then utilizes four bit codes of symmetry that the panel character distributes and ideophone coding long, to each key position tax with corresponding musical tones, thereby make the coded message languageization.Utilize this mode, computer can be used the sound symbol, evenly and breath-group reads out encode Chinese characters for computer clearly.

Advantage of the present utility model is: it had both had the accuracy of QWERTY keyboard, had the dirigibility of mouse-keyboard again, and only can import Chinese character code fast with two thumbs, had greatly simplified input mode, thereby made computer microminiaturized to greatest extent.The key knob move to the panel cursor move control only with two thumb manipulations, simple and easy to do.Realize music encoding with character-coded corresponding, computer goes to read encode Chinese characters for computer with music, becomes a kind of signal of computer language clearly.
