Description

Super general desktop keyboard

Technical field:

The present invention relates to computer keyboard, particularly, it is a kind of desktop keyboard with superpower versatility.

Background technology:

Appearance along with notebook computer, keyboard moves towards many specifications by original single general-purpose specification and deposits, the pocket notebook is when satisfying portable needs, but use its skilled operating personnel to bring the work puzzlement for really needing, keyboard uses skilled more, many more by the maloperation that specifications vary causes, and frequent transitions between the specification more can cause the infringement of touch system ability.At present, except the Qwerty keyboard layout, also there is multiple practicality and high efficiency keyboard layout, such as just letter and punctuation mark occur in sequence the DVORAK keyboard layout of change and the four-node input method keyboard layout that need not mouse that I release, especially the latter more meets following keyboard miniaturization and high portable development trend, referring to application number 200910138323.6 four-node input method and keyboard layout thereof, thereby people need be when continuing to use the Qwerty keyboard at ordinary times, progressively practise and be familiar with following main flow layout keyboard, and current desktop keyboard can only adapt to single specification, can't satisfy the support to many specifications and many layouts.Therefore, need desktop keyboard aspect versatility, to make improvements.

Goal of the invention:

The object of the present invention is to provide a kind of desktop keyboard that has many specifications versatility and support many layouts, overcome the limitation that present keyboard only adapts to single specification and single layout, make desktop keyboard can support multiple layout and the needs of depositing.

Summary of the invention:

The present invention reaches support to multiple keyboard layout and plurality of specifications by the mode of desktop keyboard being carried out one or both sides two or more keyboard specifications or layout being set, and adopt scrapping interference eliminating technology to improve the versatility of desktop keyboard, therefore, this invention keyboard has the versatility that surmounts the common-use size performance, is called super general desktop keyboard.

Utilize desktop keyboard to be independent of the advantage of miscellaneous part, adopt dual mode to carry out many specifications and the improvement of many layouts, the versatility of desktop keyboard is unprecedentedly strengthened.

One of mode is that single face is provided with different keyboard specifications or different keyboard layout.The four-node input method keyboard is little owing to keyboard size, the very light single face dual gauge that can realize keyboard; 12 inches and 10 inches notebook Qwerty keyboards also can be realized the design of single face dual gauge, here 12 inches and 10 inches keyboard of notebook computer of what is called are meant that corresponding display screen is the keyboard of 12 inches and 10 inches specifications, only needing the size of 47 character keys to conform to corresponding specification gets final product, some general utility functions key can generally be provided with, as 16 function keys of top line; The DVORAK keyboard is just different putting in order of letter and punctuation mark with existing keyboard, only needs to make mark on the right side of character keys and can realize the two layouts of single face.

Two of mode is two-sided different size or the layouts of being provided with of keyboard.Mainly be at the another side of common-use size Qwerty desktop keyboard (refer to the non-notebook Qwerty of all types keyboard here, having digital bracket panel is its basic feature), single specification or dual gauge keyboard are set.Also can adopt the two-sided form that two kinds of small dimension keyboards are set, this form can reduce the overall dimensions of desktop keyboard.

For the two-sided form that keyboard is set, need the problem of considering that back side button and loading end disengage.It is multiple to realize that this purpose scheme has, the simplest is unsettled holder, only need common key pan arrest with computer desk transform unsettled holder as and can realize this requirement, the forestock edge of unsettled holder and butt be along holding up keyboard, and keyboard back side button is broken away from and the contacting of loading end.Base plate can be arranged at the bottom of unsettled holder, also can not have base plate, and forestock also can be an activity form along being fixed form, and activity form is to realize that the inclination angle that the adjusting keyboard is placed is a purpose, and fixed form can realize that 3 °-4 ° inclination angle gets final product.For slip before and after preventing keyboard causes that keyboard drops, can solve by multiple scheme, wherein succinctly practical along the scheme that front is set at the forestock of keyboard case forward position or unsettled holder, Fig. 1 provides is that no base plate and forestock are along machine made unsettled holder structure synoptic diagram.Front is arranged at the keyboard case forward position.

For the specific design of keyboard, multiple design form can be arranged, can be divided into wired and wireless, for the design that lead is arranged, preferred plan designs for common wire.Adopt common wire, need to solve the circuit conversion problem, a power switch is set, employing has the double-throw function type and can realize, also can adopt other modes to realize.The key-press matrix circuit can design by different principle, and form is not limit.The dual surface keyboard majority needs central dividing plate.Provide basic block diagram by current most popular conductivity type thin film keyboard below, as shown in Figures 2 and 3.

After desktop keyboard is carried out above-mentioned improvement, by simple and easy scrapping interference eliminating technology and virtual extension technology, the function that can realize keyboard specification aspect breaks through, and reduces the scratching that causes because of specification is not yet done and disturbs, and the desktop keyboard universal performance is further got a promotion.

At first illustrate below in order to overcome the scrapping interference eliminating technology of specification limitation.

Scrapping interference eliminating technology is divided into simple and easy scrapping interference eliminating technology and virtual extension technology (these two technology are applied for a patent in addition with keyboard key scrapping interference eliminating technology).

Because the existence of keyboard plurality of specifications, when people carry out the specification conversion, there is the maloperation phenomenon unavoidably, scratching is to the contiguous button of purpose key in promptly operating, this phenomenon has the purpose key and adjacent key is impacted feature simultaneously, most scratching keys shows as in scanning and is later than the purpose key and is scanned, and simple and easy elimination technique carries out according to this phenomenon just that the scratching key gets rid of.

Simple and easy scrapping interference eliminating technology is achieved by the following scheme, the button that at first scans directly is defined as the purpose key, the follow-up adjacent key of being pressed simultaneously that scans is considered as the scratching key to be got rid of, but the adjacent key that needs to use simultaneously can not be done the adjacent key processing.Shift key as the Qwerty keyboard is adjacent with AZ two keys, but shift key with can not handle by repelling key between the two.

Virtual extension technology is a kind of senior scratching key elimination technique, is summarized as follows:

In order to improve the versatility of small dimension keyboard, the keyboard of notebook computer majority has adopted little spacing big key design, and purpose key and scratching key can't successively be confirmed by scanning fully, and with the specification difference, have following rule:

1: purpose key and scratching key are pressed simultaneously and are lifted.

This feature is to judge and get rid of the prerequisite of scratching phenomenon.Specify, described herely press simultaneously, press when being ordinary meaning, little phenomenon of pressing simultaneously in circuit scanning, press to show as in the time of the majority ordinary meaning and successively press, it is very of short duration that just priority is pressed the time interval, back one key or two keys are scanned when pressing after a while, formerly button is in the state of being pressed, owing to multiple reason, comprise the key jitter factor, whether the order that front and back two keys are scanned can not be represented fully is the purpose key, though in most cases be scanned early than the scratching key greatly because the purpose key is pushed strength.Lift simultaneously, similarly.

2: the people of custom small dimension keyboard is when using big specification keyboard, and the scratching phenomenon shows as the purpose key outside, and the scratching key is interior, and the people who is accustomed to big specification keyboard is when using the small dimension keyboard, and the scratching phenomenon shows as the purpose key at interior and scratching key outside.

3: when the people that hand is little uses big specification keyboard naturally, the purpose key outside, and the scratching key is interior, when the people that hand is big used the small dimension keyboard naturally, the purpose key was interior, and the scratching key outside.

4: the time interval that adjacent two keys successively are scanned is long more, and the time identification meaning of purpose key and scratching key is obvious more.

According to above rule, we can take one than simple and easy scrapping interference eliminating technology active measure more, promptly virtual extension technology.A key that meets specific tendency in two keys that this technology is pressed simultaneously by regulation is the automatic identification that effective key is realized the purpose key, and in form, therefore this technology extends for image from a kind of button of people to certain specific direction is referred to as virtual extension.

Preferential and the exclusion relations that virtual extension relation between the adjacent key is changed between adjacent key can easily carry out the judgement of virtual extension relation in operation program.Below the transforming relationship of virtual extension technology in computer program is elaborated:

Three kinds of relations that extend of common existence between adjacent two buttons are respectively unidirectional extension relation, mutual extension relation and do not have the relation of extension.For convenience of description, the button that at first is scanned in the scanning is called button formerly, surface sweeping subsequently to the adjacent key of being pressed simultaneously be called at the back button.Formerly to be defaulted as be the purpose key to button.

(1): if unidirectional extension, the button that takes place to extend is preferential button, and corresponding key is for repelling button.

When button formerly was the button that takes place to extend, formerly button repelled at the back button, and the purpose key is constant, and button is excluded in the back;

When button formerly is when being extended button, then belong to the preferential button of button formerly at the back button, the purpose key is changed at the back button, and formerly button is excluded.

(2): if two adjacent buttons are the relation that extends mutually, two adjacent buttons repel button each other.Determine the purpose key according to button priority principle formerly.

(3): if two adjacent buttons are not for there being the relation of extension, two adjacent buttons do not have repulsion and preferential button, and two keys all are confirmed as the purpose key.

The virtual extension relation table preferential and that exclusion relations is formed that is adjacent button by button has just constituted whole virtual extension scheme.Can virtual extension branch is interior to extension and export-oriented extension two classes according to keyboard integral extension tendency, but all contain mutual extension composition.Here interior to extroversion for the reference key position.The reference key position is to determine by the target group of corresponding specification and correct operation technique, scratching takes place in two adjacent reference key positions, handle by extending mutually, promptly determine validity by the priority of scanning and affirmation, what scan earlier and confirm is effective, only assert that promptly the button that at first is scanned and confirms is the purpose key, and be scanned subsequently and the button confirmed is considered as the scratching key and is directly got rid of.

In when extending, the reference key position is pressed simultaneously with adjacent non-reference key position, adjacent non-reference key position is the purpose key, just as outside non-reference key position to extension taking place in interior reference key position direction; And during export-oriented the extension, the reference key position is pressed simultaneously with adjacent non-reference key position, and the reference key position is the purpose key, just as to outside non-reference key position direction extension taking place in interior reference key position; When extending mutually, be the purpose key, because two adjacent buttons all might at first be scanned, therefore do not have fixing extension tendency, just as taking place to extend mutually to the other side with the button that at first is scanned affirmation.In a sense, extending mutually is a kind of simple scratching elimination technique, it is the epitome of simple and easy scratching elimination technique, introversive and export-oriented the extension then is real extension technology, provide convenience for the user utilizes this extension relation consciously, this is the reason that this measure is called active measures.

The Qwerty layout of knowing with everybody is an example, can be with the ASDFJKL of Qwerty keyboard; Eight keys are decided to be the reference key position, interior outwards extension when extending, outwards extend during export-oriented the extension, WE two keys and IO two keys extend mutually, the Q key extends to AW two keys, in being called to extension, when QW two keys or QA two keys are pressed simultaneously, the Q key is regarded as the purpose key, is excluded and W key or A key are regarded as the scratching key.Same ASDF quadruple linkage and HJKL quadruple linkage are the relation that extends mutually, also are the relation that extends mutually between the ZXCV, and when being pressed simultaneously between Z key and A or the S, the Z key is considered as the purpose key, and this is the performance of inwardly extending.All the other in like manner.

In help little people of hand or the people from skilled small dimension keyboard to extension when using big specification keyboard, keep versatility between two specifications, for people on top of the pocket keyboard of notebook computer removed the misgivings of imitating others and thus losing one's own individuality, the export-oriented personage who then helps skilled big specification keyboard of extending uses own unskilled small dimension keyboard.Therefore, on desktop keyboard and full-scale keyboard of notebook computer, adopt the extension scheme of being inclined to extension in having, have the export-oriented extension scheme that extends and be inclined to and on the small dimension keyboard of notebook computer, adopt.

Adopt virtual extension technology, content comprises virtual extension scheme and defines the time limit.The two adjacent buttons of pressing simultaneously can be determined purpose key and scratching key by preferential and exclusion relations according to virtual extension scheme, this is a unilateral rule of not considering the key scan time order and function, because the time phase difference that adjacent two keys are scanned is big more, the button that at first is scanned is that the probability of real purpose key is big more, therefore, implement virtual extension technology and must consider the Practical significance of difference sweep time, this just must give the use setting-up time boundary of the virtual rule that extends, be called and define the time limit, defining in the time limit, preferential and exclusion relations according to adjacent key is determined the purpose key, get rid of the scratching key, surpass and define the time limit, the adjacent key of then follow up scan being conducted electricity is directly got rid of as the scratching key.It is long more to define the time limit, and virtual extension meaning is heavy more, but the sluggishness that forms is obvious more, defines the time limit and can select between 20ms～100ms.

Super general desktop keyboard is by providing the two or more specifications of two kinds or above keyboard layout or a kind of layout keyboard, thereby facilitate for different skilled specified arrangement of user of service or specifications, when adopting the unification of four-node input method dual gauge keyboard and Qwerty keyboard, can be simultaneously, the personnel of all uses from primary school to the adult or four-node input method keyboard on probation can not influence use, for last obstacle is got rid of in the popularization of four-node input method keyboard to the Qwerty keyboard for providing seamless keyboard support.By adopting simple and easy scrapping interference eliminating technology or virtual extension technology, increased the versatility and the convenience of this keyboard from more wide scope, reduce the interference that scratching brings, when improving ease of use, also improve input speed.

(5) dish two thumb button in a left side are of a size of 22mm*37mm+21mm*17mm, and right dish two thumb button are of a size of 22mm*35mm+19mm*17mm;

(6) primary and secondary specification keyboard overall dimensions is 41cm, and the centre can keep the appropriate intervals of 1cm.

Annotate: more than be the size of not considering under the situation of button end face size, can design the above specification button of slope-less certainly fully.Fig. 6 is bevelled a kind of design of button keycap and arrangement, gray area is represented inclined-plane (21), middle white Regional Representative button end face (22), button end face size is respectively dwindled 2mm in length and breadth than top specification, its arrangement is a kind of typical interior button hardware fit step to the extension scheme, be that big specification tilts to small dimension, the quantity of button scratching or scratching simultaneously or to strengthen sweep time of scratching key and purpose key poor in the time of can reducing hand person of low position scholar and use.10 pilot lamp (19) are arranged at the position of right dish (18) top near the left side, and two dishes are shared, as shown in Figure 4.

As Fig. 2 and shown in Figure 4, A face dual gauge four-node input method keyboard is made of left side dish (17) and right dish (18), pilot lamp (19) is positioned at the position of taking back, right dish (18) top, the B face is provided with existing desktop computer Qwerty keyboard, all adopt the conductive film keyboard technique of at present main flow, the two sides keyboard all can be used as top and bottom, be that the positive back side occurs, by the keyboard case (8) of correspondence, button (9), conductive film (10) and corresponding microcontroller and circuit board constitute, only represented conductive film among Fig. 1, the centre is provided with dividing plate (11), and two sides keyboard sharing lead (12) realizes that by power switch (13) energising of front, place keyboard is enabled.

As shown in Figure 3, power switch (13) is made of the dual-purpose plug (14) and the auxiliary spring (16) of symmetry, outreaches common wire (12), and with corresponding socket (15) formation complete circuit, socket (15) and keyboard microcontroller separately link.During use power switch (13) is dialled to the right, dual-purpose plug (14) is connected with right side socket (15), and the front keyboard is enabled, and back side keyboard is idle, by the pressure of auxiliary spring (16), guarantees the stable UNICOM of plug (14) and socket (15).

Keyboard during use (2) places in the unsettled holder (1), unsettled holder (1) is installed on the computer desk, its forestock is used for keyboard (2) is held up along (4) along (3) and butt, before drag between (3) and butt edge (4) and do not have base plate, front (6) is positioned at the front and back of housing forward position (5), be used to stop keyboard (2) to move forward and backward and scratching back side button, at a distance of 12.5cm (i.e. Zhong Jian unsettled distance), forestock edge (3) is than butt edge (4) high 8mm along (4) for forestock edge (3) and butt.

Virtual extension technology is an innovation to the keyboard using method, is the important measures that strengthen the keyboard versatility, also is to reduce the best means of scratching phenomenon to the input speed influence.At first describe the virtual extension scheme of four-node input method keyboard below in detail.

The virtual extension scheme of four-node input method keyboard can show visually by Fig. 6, this be one typical in to the extension scheme.Fig. 6 represents the virtual extension direction of button with extension arrow (20), two arrows are represented relatively and are the relation that extends mutually between two buttons, single arrow represents that two adjacent buttons are unidirectional extension relation, there is not arrow to represent not concern for having to extend between this two button that what corresponding button center marked is the key position of determining according to following table 1 between the two adjacent buttons.Here the extension scheme that it is emphasized that button is a core, and the key position has different results according to different matrixes, here both is put together, is for intuitively.

The virtual extension rule of four-node input method keyboard is as follows:

For convenience of description, here distinguish called after left hand little finger of toe row from left to right according to the corresponding relation of this keyboard and finger, the nameless row of left hand, left hand middle finger row, left index finger row, left hand thumb row, the hand thumb row, right hand forefinger row, right hand middle finger row, right ring finger row and right hand little finger of toe row, totally 10 row.

(1): as seen from Figure 6, right-hand man's third finger row and middle finger row two row are gone together and are extension relation mutually between the button, represent with two relative arrows, and the adjacent key of going together between forefinger row and thumb row and the two thumbs row also is the relation that extends mutually, note between the end line unit exception being arranged.

(2): as seen from Figure 6, the little finger of toe of left hand dish and right hand dish row and forefinger row extend to the centre separately, and axis is nameless row and middle finger row, notes between the end line unit exception being arranged.

(3): vertically, the left hand dish is an axis with subscript key and subscript key, and right hand dish is an axis with 5,6 liang of keys, and other each row entad show as and extend, and four row and both hands little finger of toe row is different in the middle of noting.

The cause description of exception phenomenon:

(1): left side 5 keys of end row 8 keys are the function collateral key, and reason is to exist between adjacent two keys uses phenomenon simultaneously, or facilitates for later functional development.

(2): only and between the thumb side of the listing button there is virtual extension in two thumb button, and no virtual extension between other button, have between reason is separately and use phenomenon simultaneously, generate new function.

(3): 0 key upwards extends and more meets the use habit of little finger of toe, and the downward extension of two hand forefingers row and left hand little finger of toe row then is to pause in order to reduce in literal and the letter input.

(4): two thumbs row all adopt downwards and extend more convenient use.

By above introduction, there are three kinds of relations in we as can be seen between adjacent two keys, promptly unidirectional extension relation, extend relation and do not have the relation of extension mutually.

When two keys that show as unidirectional extension relation were pressed simultaneously, the button that takes place to extend was confirmed as the purpose key, and another button is excluded; When two keys showed as mutual extension and concern, two keys were pressed simultaneously, and the at first double button that is scanned is confirmed to be the purpose key, and another button is excluded; When adjacent two buttons that do not have the relation that extends are pressed simultaneously, there is not button to be excluded.

It is to increase versatility convenience is provided that unidirectional extension is closed, and it is more convenient that keyboard is used; The extension pass is to get rid of the scratching phenomenon that occurs in the use solution is provided mutually, can get rid of most scratching and disturb, and slips up even affirmation takes place, and has also made things convenient for modification; The relation that keep not have extends is that two keys use simultaneously and provide convenience.

Here lay special stress on, when keyboard entered the mouse function state, cancellation left hand dish A key was to the extension to the O key of H key and U key, to guarantee mouse pointer oblique movement function.The AHOU quadruple linkage here is the key name of four joint position keys of left hand dish, under the mouse function state, represents four moving directions of mouse pointer, please referring to shown in Figure 5.

The key-press matrix circuit is the circuit implementation of keypress function, identical functions can be designed multiple circuit, the circuit matrix of a kind of simple 8*20 is provided here, horizontal 8 parallels, vertical 20 warps, left side dish and right dish parallel are general, each 10 of warps, in order to express easily, represent 8 parallels from top to bottom, represent from left to right 20 warps with J1～J20 with W1～W8.

Tabulating with corresponding button in the dish warp and weft point of crossing, a left side that is reflection key-press matrix material relation below, is called table 1.Because right dish tabulation is identical except that corresponding warp label, is simple and clear meter, right dish cart lattice omit.According to table 1 and Fig. 5 and about coil button size, the professional can design corresponding left side dish and right dish matrix circuit.Cell is that empty expression warp and weft is non-intersect, and cell Chinese words, letter, numeral, punctuate etc. are according to the set button key name of four-node input method keyboard layout.
