Description

Universal computer keyboard

The present invention relates to a kind of universal computer keyboard.

The computing machine that uses comprises the key position layout of keyboards such as desktop computer, portable machine at present, and the character input can be finished by the both hands touch system basically.With reference to the key position layout of the PC keyboard that uses at present, therefrom shift key Alt and operating key Ctrl are arranged on end row as can be seen, and right shift key Shift is arranged on/right side of key, and they and base key position are all far away.When the both hands touch-typing operation, two hand fingers are placed on base key and the space bar position, and will use this moment one of Alt, Ctrl, right each key of Shift and character keys to carry out combination operation is not easily, as when press Alt, Ctrl, each is pointed and wrist all will inwardly bounce back; During by right shift key, the overhanging also effort of right hand little finger of toe, these all influence the convenience of keyboard operation and the dirigibility of finger keystroke, and undue force is also tired easily.

The definition of numeral was not same row when the key position layout of numeric keypad and portable machine master keypad were locked as digital state, the defined key of sign of operation position is not consistent yet, the difference that causes the used finger of keystroke, this for the user operates different keypad inputs make troubles.

The keyboard that all can finish by the both hands touch system when purpose one of the present invention is to provide a kind of Alt of making, Ctrl, each key of Shift, Windows and character keys to carry out two key combinations operation; The key position definition of its two numeral when being to make the key position layout of numeric keypad and master keypad to be locked as digital state and sign of operation is consistent, so that the general user can therefrom save numeric keypad when using desktop keyboard; But it three is the braille keyboard and the blind person's computing machine that provide a kind of blind man to manipulate.

At present people generally believe two character keys of master keypad/, [,] to wait be indispensable also inconvenient mobile, otherwise can influence the convenience of operation.The present invention has overcome this prejudice, for achieving the above object one, master keypad will/, [,], ,～five two character keys in～, [,] triple bond moves to the leftward position of end row's space bar ,/, two keys move to the right positions of space bar; Or above-mentioned five keys are saved from keyboard, then will " key moves to the former [position of key, P key right side.When above-mentioned five keys save, ten symbols { } on its key face～,/[]? | can be arranged in the lower right corner of master keypad 10 numeric keys key face successively, symbol on perhaps on this basis will the character keys key face except that letter key is done the part adjustment, accompanying drawing 1 has marked the character definition of adjusting each key key face of back, and key face lower right corner symbol is by Ctrl+ " symbol place key " control input.Following row's character keys and the last row's character keys bond distance that staggers 1/4 character keys from top to bottom successively to the right in the master keypad, Alt, Shift, three pairs of combination function keys of Ctrl are arranged in Q from top to bottom successively and arrange that (Q-"), A arrange (A-; ), two side positions of Z row (Z-.) character keys, two Windows keys are arranged in two Ctrl lower positions.Each key of 1QAZSE4 can be linked to be the tilted letter V of a standard in the master keypad, same each key of 5TGBHU8 and 9OL.; "+each key also can be linked to be same two tilted letter V, and therefore above-mentioned keyboard is called the V-type keyboard.With the editting function key, soft function key and some other function keys of mark F are all incorporated master keypad into before the numeral in the V-type keyboard, and concrete keys arrangement is seen accompanying drawing 1,2.。

The master keypad character keys that is provided with in the present portable machine keyboard is locked as the digital state function and can be used in the desktop keyboard.Original key position layout when having upset the master keypad character keys after/key moves or saves and being locked as digital state, for being consistent with the key position layout of numeric keypad, the numeral definition that makes the master keypad character keys realizes above-mentioned purpose two simultaneously, to at master keypad/, * ,-,+be defined on 7,8,9,0 quadruple linkage, 7,8,9. be defined on U, I, O, the P quadruple linkage, 4,5,6,0 be defined in J, K, L; On the quadruple linkage, 1,2,3 are defined in M. on the triple bond, in addition () is defined on-+two keys, equal sign or carriage return are defined in " on the key; In numeric keypad, 0. liang of key is moved to 6,9 liang of key right positions, /, * ,-,+be defined in 7,8,9. the quadruple linkage top position, num lock key Num Lock moves to the lower left corner 1 key lower position, 2,3 liang of key lower positions are set up tabulation positioning key Tab and backspace key Backspace, to enlarge its function, the former key invariant position of enter key Enter.Num Lock key can save in the numeric keypad in addition, changes to be made as ESC Escape Esc, and this district can an encumbrance word state cancel editting function, or enter key is divided into Enter and Num Lock two keys.Especially for bank counter input password, the numeric keypad of aspects such as the self-service consignment trade of security system, the Backspace key can make the Clear key into ,/, * ,-,+quadruple linkage can change F1, F2, F3, F4 quadruple linkage into.

For achieving the above object three, the keycap of V-type keyboard is made tangibly type or character cut in bas-relief braille key face, and horizontal and vertical raised line or salient point are set at surface of keyboard keypad periphery, what have can be projection or recessed arrow and circle, as the below of cursor among Fig. 1 to left and right, following shifting bond(s), Pause, left Shift two key lefts, Pause, Enter two keys are right-hand can be arrow; The top of F1, F5, F9, PrtSc quadruple linkage can be circular.By touching these projectioies and the recessed position that just can determine respectively to arrange key down to each key easily, make the braille keyboard.Develop computer software, be configured in the computer system that adopts the braille keyboard, but make the computing machine that blind man uses with voice suggestion and record function.

Beneficial effect of the present invention is to have unified desktop computer, the keyboard layout of portable machine or other type keyboard master keypad, and when the keys arrangement in the V-type keyboard had solved two key combinations operation, the problem of two key inconvenience was made a call in both hands touch system input and singlehanded input on the other hand.When one hand impacts not two keys same row in the lump, as Alt+F1, Shift+Ctrl, Ctrl+Backspace etc.; When one hand impacts two keys that are positioned at same row in the lump, as Shift+F, windows+Tab etc., for have only a hand can with the individuals with disabilities provide convenience.When the key position layout of numeric keypad and master keypad character keys were locked as digital state, the unification of key position definition allowed when using different keypads to carry out same operation, can use similar fingering to operate.Braille keyboard and blind person's computing machine are that the work of blind person's operational computations machine, study, life are provided convenience.
