Abstract

The utility model relates to a computer input equipment, in particular to a symmetrical distributed keyboard. The utility model is to change the defects of irrational design and non-smoothness of operation of the keyboard and design out the symmetrical distributed keyboard which results in consistent hand operation position with the direction of movement, comfortable use, and convenience for acquiring. A left hand keyboard region and a right hand keyboard region of the utility model are shown in the left and right symmetrical trapezium distribution to achieve symmetry of left and right fingerings and achieve improved amenity and accuracy of the input.

Description

The symmetric distributed keyboard

The utility model relates to a kind of computer entry device, particularly relates to the keyboard that carries out literal, symbol, letter input.

No matter present computer keyboard is general QWERTY keyboard or ergonomic keyboard, its key position, major key panel arrange be in the vertical from top to bottom, the unidirectional trapezoidal arrangement of tilting from left to right, the structure naturally that finger presents when not meeting the human body typewriting, cause operation to have some setbacks, button is inaccurate, influence input speed, and fatiguability and cause the damage at positions such as finger, wrist.

It is neat, reasonable that the purpose of this utility model provides a kind of each key distribution, is easy to study, memory, operates the distributed keyboard of left-right symmetric ladder accurately and fast.

In order to achieve the above object, the utility model is to realize like this.That is: the right-hand man with the major key panel distinguishes, and forms left-right symmetric and distributes, and backspace key is placed between letter key B and the letter key N the corresponding separately descending numerical key of function key.

To the trapezoidal arrangement of keyboard left-right symmetric, realized the symmetry of left and right sides fingering by above, and corresponding up and down neat, each key position is simple, easy note, operate smooth and easy, accurate because each key position is constant, can not cause the confusion with existing keyboard, and on producing, increase cost hardly.

For explanation better, (embodiment) is further described the utility model concrete structure below in conjunction with accompanying drawing.Fig. 1 is a plane structure chart of the present utility model, and Fig. 2 is that the utility model is implemented in the plane structure chart on the notebook computer.

Letter key Q～the T that will have keyboard among Fig. 1 now shifts out to the right and next line letter key A～G consistency from top to bottom, same letter key Y and thereafter each key move to right and next line letter key H and each key consistency from top to bottom thereafter being spaced a distance of this left and right sides two parts; Letter key Z～B shifts out two row letter key left ends, 1/5～1/4 key position left, and formation left hand district is tilted to the left, right hand region is tilted to the right; Cancel key is placed between letter key B and the N, than single letter bond distance; Separately, numerical key 1～5 key moves right numerical key between 5 and 6, and its right-hand member exceeds two row letter key right-hand members down, accordingly numerical key 6 and thereafter each key move to right and the left side forms symmetric position; The corresponding descending numerical key of each key of function key is arranged; Adjacent with lastrow respectively each the key consistency from top to bottom of each key adjacent with the enter key left and right sides.

Claims

1, a kind of symmetric distributed keyboard that is used for computword, letter, symbol input, this keyboard has major key panel, function key area, control/cursor district, numeric keypad, it is characterized in that the right-hand man's differentiation in the major key panel is split into symmetrical trapezoidal profile, the left hand district is tilted to the left, right hand region is tilted to the right, corresponding up and down neat, cancel key is between letter key B and N.

2, symmetric distributed keyboard according to claim 1, it is characterized in that keyboard left hand district letter key Q～T moves to right and next line letter key A～G consistency from top to bottom, keyboard right hand region letter key Y and thereafter each key move right and align with next line, reserve the space between this left and right region, letter key Z～B moves to left and is tilted to the left, letter key N, M and thereafter three symbolic keys move to right and be tilted to the right, numerical key 1～5 moves to left and descending "Left"-deviationist, the corresponding arrangement with numerical key of function key, it is corresponding separately that each key adjacent with the enter key left and right sides caught up with delegation.

3, symmetric distributed keyboard according to claim 1 is characterized in that cancel key between letter key B and N, and length is longer than a letter key length.

4, symmetric distributed keyboard according to claim 1 is characterized in that the utility model keyboard Designing scheme also is applicable to keyboard of notebook computer.
