Abstract

A kind of computer keyboard is applicable to desk-top computer and notebook computer.The right side of letter key on keyboard " L " is a backspace key (a2), and this backspace key (a2) connects the backspace key circuit of keyboard on electric line.When the finger of the right hand was placed on the reference key of keyboard, the little finger of toe of the right hand just was placed on this backspace key naturally.In the time of like this will be,, need not moveable finger fully or rotate wrist, can improve accuracy, agility and comfortableness that keyboard is imported as long as right-handed little finger of toe is directly pressed this key by backspace key.

Description

A kind of computer keyboard

Technical field

The utility model relates to computer input unit, specifically a kind of computing machine (comprising desk-top computer and notebook computer) keyboard.

Background technology

Now the desktop computer keyboards overwhelming majority who generally uses is rectangle (as shown in Figure 1), and it is to be divided right and left and formed the human engineering keyboard of certain angle by left hand keypad and this two macroplate of right hand keypad that small part is also arranged; Keyboard on the notebook computer (as shown in Figure 4) then is directly to be made in above the computer body, becomes the indispensable parts of notebook computer.Keypad on the keyboard is divided into the major key panel usually, and numerical keypad district, F key function key panel, control keypad also have quick keypad for Multi-Function Keyboard.

On the keyboard that generally uses now, backspace key (Backspace also claims back spacer) be positioned at the major key panel the upper right corner (Fig. 1-a1, Fig. 4-a1), its weak point is:

When importing with keyboard, backspace key is to knock one of the most frequent key, because usually will be by deleting by this key behind the input error character, but this key be positioned at the upper right corner in major key panel on conventional keyboard and keyboard of notebook computer, need the mobile right hand could be by arriving by this key.So frequent moveable finger or palm, wrist can make hand that fatigue, discomfort even pathology take place.Because this key is from reference key (the correct placement location of finger on keyboard when just operating, the forefinger, middle finger, the third finger that are the right hand are placed on respectively on letter key " J ", " K ", " L ") far away, by this key the time, to could so just influence the accuracy of input speed and keystroke accurately by arriving with this key of eyes toward contact.When finger playbacked (just being put on the reference key) once more after having pressed this key, right finger also was difficult to accurately be put on the reference key quickly, and particularly for the vast computer operation person who is not professional typist, this shortcoming is just more obvious.

Summary of the invention

In order to overcome the above-mentioned shortcoming of active computer keyboard, the purpose of this utility model provides in a kind of the use without moveable finger or rotates the keyboard that wrist just can be knocked backspace key.

The technical scheme that the utility model adopted is: the right side of letter key on keyboard " L " is provided with a backspace key, and this backspace key connects the backspace key circuit of keyboard on electric line.When the finger of the right hand was placed on the reference key (just the forefinger of the right hand, middle finger, the third finger are placed on respectively on letter key " J ", " K ", " L "), the little finger of toe of the right hand just was placed on this backspace key naturally.In the time of like this will be, as long as right-handed little finger of toe is directly pressed this key by backspace key.

Originally be positioned at letter key " L " right side "; " key (or other button) can move on to original backspace key place, just will have now backspace key on the keyboard and letter key " L " right side "; " key (or other button) location swap.Since backspace key knock frequency than "; " key (or other symbol keys) is much bigger, therefore backspace key is placed on better the using in right side (be right finger when being placed on the reference key, this backspace key is positioned at below the right hand little finger of toe) of letter key " L ".

The beneficial effects of the utility model are: when needs are pressed backspace key, this backspace key that is positioned under the right hand little finger of toe is just passable as long as directly press with right hand little finger of toe, need not moveable finger fully or rotate wrist, can improve the comfortableness of input speed and use keyboard.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of existing conventional keyboard.

Fig. 2 is the structural representation of an embodiment of the utility model.

Fig. 3 is the partial enlarged drawing of dotted line part b among Fig. 2.

Fig. 4 is the structural representation of existing common keyboard of notebook computer.

Fig. 5 is the structural representation that the utility model is used for an embodiment of notebook computer.

Fig. 6 is the structural representation that the utility model is used for another embodiment of notebook computer.

Embodiment

With reference to Fig. 2, Fig. 5, Fig. 6, the utility model keyboard is in total structure, the same substantially on the formation with existing keyboard, comprise base (contain on the notebook computer fixedly the base plate of keyboard), keyboard electric line and button (contain keycap, parts such as elastic component), difference is the backspace key (Fig. 2 on the utility model keyboard, Fig. 3, Fig. 5, a2 among Fig. 6) is positioned at the right side of letter key " L ", just with the forefinger of the right hand, middle finger, the third finger is placed on letter key " J " respectively, " K ", in the time of on " L " these three reference keys, the little finger of toe of the right hand just in time is placed on this backspace key (a2) naturally.

This be positioned at letter key " L " right side backspace key can with letter key equally big, also can be letter key twice or more than.

Figure 5 shows that the same big keyboard of backspace key (a2) with letter key.

Fig. 2, Fig. 3, Figure 6 shows that the keyboard that backspace key (a2) is bigger than letter key.

On electric line, and this backspace key (a2) and existing backspace key (Fig. 1-a1, Fig. 4-a1) the same, the contact of button (or button electric capacity tie point) connects the backspace key circuit of keyboard.Just pressing this backspace key (a2) back generation backspace key key (in windows operating system, the key of backspace key is 8).

On mechanical realization, this backspace key (a2) is identical with other button on the keyboard.

In addition, on the keycap of this backspace key (a2), generally also do the identifier of backspace key: " ← " or " Backspace ", " ← Backspace ".

After this backspace key (a2) has been arranged, be positioned at originally the upper right corner, major key panel backspace key (Fig. 1-a1, Fig. 4-a1) both can keep also can be arranged to it button of other function, as "; " key, ": " key.

Fig. 6 embodiment is depicted as right side, enter key (c1) the keyboard (comprise desktop computer keyboards and keyboard of notebook computer) letter key " N ", " M " below or letter key " C ", " V " below of backspace key (a2) at letter key " L ".On this keyboard, the most used enter key and backspace key can directly be depressed input with thumb and little finger of toe respectively and need not moveable finger again or rotate wrist, therefore can obviously improve the comfortableness of input speed, keystroke accuracy and use.
