Description

Seven row contain the ergonomic keyboard of independent digit keypad

Technical field

The utility model relates to a kind of novel keyboard, relates in particular to the ergonomic keyboard that a kind of seven row contain the independent digit keypad.

Background technology

Most convenient instrument efficiently when keyboard is the computing machine input characters, general keyboard all comprises function key, letter key, editor's operating key and four basic keypads of numerical key, wherein, alphabetical keypad is arranged according to the arrangement mode of machinery typewriter, the replacement of keeping right and being close to, page turning, function keys such as direction, again to the right, it is numeric keypad independently, this is because common computer keyboard uses on the desktop of fixed location usually, less demanding to portable performance, and on the keyboard of notebook computer, in order to reduce whole volume, the compression that the area of keyboard need be tried one's best, just independently has removed the numeric keypad, when using notebook computer, simple input digit is just very inconvenient but so.The keyboard that has can switch to numerical key with 10 letter keys by a switch key, and this is inconvenient operation on the one hand, use numerical key at every turn before, all must press switch key earlier, increase the step of using, letter key is misaligned on the other hand, also independent when doing the numerical key use, use both uncomfortable, also easily make mistakes, also make things convenient for the right hand to use, concerning being accustomed to left-handed user only for ground, very inconvenient, referring to accompanying drawing 1.

In addition, existing keyboard all is six line unit dishes, triplex row in the middle of letter key accounts for, the letter key of right-hand man's correspondence is tightly continuous, and both hands must be close together both hands when knocking letter key, both hands with take on down " V " shape, make both arms in when operation owing to exert all one's strength and fatiguability, do not meet the requirement of ergonomics, referring to accompanying drawing 2.

The utility model content

In order to overcome the little deficiency that does not just have independent numeric keypad of present keyboard volume, the utility model provides a kind of seven row to contain the ergonomic keyboard of independent digit keypad.This keyboard not only has independently numeric keypad (containing directionkeys), also integral layout is reduced to minimum, no matter and be to be accustomed to the left hand or the right hand, the numeral input is all very convenient, realize the tidemark that " left hand keyboard; right hand mouse " works simultaneously, improved work efficiency, comfort greatly.

The technical scheme in the invention for solving the above technical problem is, the keyboard arrangement line number is established seven row altogether, and be divided into separately independently three districts, independently numeric keypad and directionkeys are located at the middle part of seven line unit dishes, alphabetical keypad is divided into two parts, corresponding right-hand man's use respectively, be distributed in the both sides, numeric keypad, independently the numeric keypad comprises numerical key and directionkeys and calculation keys, "+", "-", " * ", "/" four calculation keys, " 0 " to " 9 " 10 numeric keys are arranged, reach " ← ", " ↓ ", " → " " ↑ " four direction key; And being the scheme of 2 kinds of independent digits, directionkeys that met the needs of different users special optimal design, 1 numeral and directionkeys keep flat; 2 numerals and directionkeys angled protrusions.

The beneficial effects of the utility model are: independently numeric keypad and directionkeys are located at the middle part of keyboard, no matter the user is accustomed to using the left hand one-handed performance, or the convenience that the right-handed one-handed performance is all the same, and meet the requirement of ergonomics, can allow user's alphabetical keypad that the right-hand man is corresponding respectively separate and keep certain distance, be fit to the natural form of human body, make user's both arms painstakingly keep drawing close, operate more random; Keyboard is made as seven row, in littler area, the space of more button has been arranged, the more function key also can be come in the keyboard as the multimedia function key, realized multiple functionally, external form is small and exquisite, operates characteristic such as random in one.

Embodiment

As accompanying drawing 3, shown in 4, the keyboard arrangement line number is established seven row altogether, perpendicular row are divided into separately independently three districts, the centre is numeric keypad independently, about two alphabetical keypads be distributed in the both sides of numeric keypad, numeric keypad top line independently, be " PRING SCREEN ", " SCROLL LOCK ", " PAUSEBREAK " three function keys, second row is "+", "-", " * ", "/" four calculation keys, the third line is " 7 ", " 8 ", " 9 " three numerical keys, fourth line is " 4 ", " 5 ", " 6 " three numerical keys, fifth line is " 1 ", " 2 ", " 3 " three numerical keys, the 6th row is " 0 ", " ↑ ", " ENTER " three buttons, the 7th row is " ← ", " ↓ ", " → " three directionkeys, top two row of on the left side letter key are ten F function keys of F1-F10, two row are multimedia and page turning on the right, function keys such as replacement.

In accompanying drawing 5,6 illustrated embodiments, numerical key and direction keypad and other keypads are in a plane, and the key face of other keys in one plane on the key face of numerical key and directionkeys and the keyboard.

In accompanying drawing 7,8 illustrated embodiments, lift independent digit keyboard and direction keypad upper end, the upper end, plane, key face place of numerical key and directionkeys is lifted, be raised in the plane, key face place of other keys on the keyboard, make the user be easier to discern independent digit keyboard and direction keypad.

In sum, the utility model is the ergonomic keyboard that a kind of seven row contain the independent digit keypad, no matter the user is accustomed to using the left hand one-handed performance, or the convenience that the right-handed one-handed performance is all the same, and meet the requirement of ergonomics, realized multiple functionally, external form is small and exquisite, operates characteristic such as random in one.
