Description

Fast operating British system keyboard

The utility model belongs to the operating means of a kind of electronics keyboard made in Great Britain, also can be described as to belong to a kind of new-type keyboard made in Great Britain.

Robot calculator, present information treatment facilities such as computer typewriter and telex machine all are the keyboards made in Great Britain of employing standard at present.Keyboard has become human both hands by oneself to transmit the important tool of information.The rational deployment of each button on the keyboard has brought very big convenience for people in use.But because its number of keys is more, and people's finger can only be pressed a button at every turn, therefore, although skilled operator can have operating speed faster.But, because following several factors make great majority use operator's's (comprising skilled operator) of traditional keyboard made in Great Britain operating rate to be restricted.

(1): finger is from key during work.For pressing next key exactly, generally need to cooperate, for certain finger finds the key position through eyes.

(2): since the keyboard distributed areas than arm fixedly time finger can touch greatly regional.Arm is essential when therefore operating moves.

(3): general people uses traditional keyboard made in Great Britain, and is difficult to accomplish that ten fingers can both handle very skillfully.This has been equivalent to reduce the approach of the information of transmitting.

The first above factor has also limited the blind person to the use as modern instruments such as robot calculator, computer typewriter, telex machines.

The purpose of this utility model is to provide a kind of effect that can give full play to people's limbs, improves the speed of operation keyboard, can replace traditional keyboard made in Great Britain, and the quick operation that the blind person also can be used keyboard made in Great Britain.

Quick operation of the present utility model keyboard made in Great Britain is made up of control circuit and these two parts of operation keyboard.Operation keyboard is made up of hand controller and foot control device again.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is control circuit figure of the present utility model.

Fig. 2 is a hand controller structural representation of the present utility model.

Fig. 3 is a foot control device structural representation of the present utility model.

As shown in Figure 1, the control circuit of fast operating British system keyboard of the present utility model comprises by a plurality of logic gates, several accuse key control module M that switching lines and several shift control lines form and the control module N of the shift control line that forms with decoder F. In module M, remove to control the electronic switch that is formed by corresponding logic gates by accusing the logical relation that switching line and shift control line consist of. If this logic gates is selected three inputs and when door, each enters to hold with the signal of conventional keyboard button with the c pin of door and is connected, and the d pin goes out to hold with the signal of conventional keyboard button and is connected. So just, can use fast operating British system keyboard of the present utility model at all facilities that use traditional British system keyboard.

Such as Fig. 2, shown in 3, the operation keyboard of fast operating British system keyboard of the present utility model comprises two with accusing key and pushing operating key, realizes stepping on control key with the gripping type hand controller Z of hand control gauge tap and two with front and back, realizes the foot-operated foot-operated foot control device J that controls gauge tap.

Two hand controllers respectively are two control sticks, and each control stick is held manipulation by one. It is made of grip and base. Grip (1) is articulated on the base (4), erects in base. Grip can be made universal swing take pin joint as supporting-point simultaneously. Each finger institute corresponding contact part at grip (1) respectively has a Self-resetting elasticity gauge tap (2) to consist of the keyboard of charge key. Finger is on-state when pressing switch, otherwise is off-state. Therefore, ten be can obtain and key and corresponding ten charge switching lines accused. In addition, because the four direction all around of grip (1) lower end and support plinth (4) contact jaw all is equipped with Self-resetting elasticity gauge tap (3), so when pushing handle handle, also can touch respectively four gauge taps. Can obtain so again four gauge taps and four corresponding thread switching controls.

The foot control device is pedal (5) formation of central protuberance by matrix support plinth (7) and one side.Preceding and the back two ends of pedal (5) are equipped with one respectively from the foot control keyboard of elasticity gauge tap (6) formation that resets.When pin was set level, front-rear switch all was off-state; When pin inclines when putting forward or backward, the corresponding switch in front and back is on-state.Like this, each foot control device all can obtain two foot control keys and thread switching control thereof.

By the operating position branch, the button of traditional keyboard made in Great Britain can be divided into two big classes.The first kind is the category-A key.Its feature is independently to use, and each button produces an independently code respectively.The second class button is the category-B button, and it must be used with the category-A button, makes it to produce other one group of code.This class button has " upper blocking key " and " operating key " etc.Some equipment need be pressed several buttons sometimes simultaneously and finish a certain operation, and this is another generic key outwardly, but in fact this is that some specific key is finished a certain specific operation jointly, and its equivalence is the category-A key.Its equivalence is the several switching points of switch drive on circuit.The utility model is controlled two gauge tap (being the foot control key) respectively with fixing respectively control ten gauge tap independent of each other (promptly accusing key) of ten fingers, every pin.Control respectively and the identical electronic switch of traditional keyboard number made in Great Britain by the different switch combination states of these switches.Reach former keyboard of generation with these electronic switches, thereby realize the purpose of this utility model.Certainly, sometimes for easy to use, also the button of finishing specific function that some seldom can be used or some special key independently go out above imagination and are contained in other position.In addition, when the gauge tap of quick operation of the present utility model keyboard made in Great Britain is less than 18, only also can realize its whole gauge tap with two hand controllers.The utility model has been broken traditional keyboard structure, is satisfying hand and pin not under the situation of key, people can be brought into play use quick operation of the present utility model keyboard made in Great Britain freely.

Quick operation of the present utility model keyboard structure made in Great Britain is simple, and operating speed is fast, accurately, has given full play to the effect of people's limbs.Can under the situation that does not change existing soft, hardware, be applicable to the equipment of any use electronic keyboard made in Great Britain.And it also is applicable to the blind person.

According to the function of tradition keyboard made in Great Britain, the utility model realizes that the method for category-A key is with ten finger control ten gauge tap independent of each other (promptly accusing key k10-k19).And these ten logical relations that switching line (promptly accusing switching line L10-L19) is common and some gear control lines (being L21-L29) composition is certain of accusing key.For ease of understanding, we allow its form " with " logical relation.When certain accused that key is pressed, it accused that accordingly the state of switching line just is " 1 ".And its with some gear control lines mutually " with ".Therefore, have only when certain bar gear control line also is " 1 ", could produce a switch motion.Like this, each button of finger control can have and the identical on off state of gear control line number.If retaining is K for control line line number, the present invention also just can realize 10 * K on off state so.Each on off state drives an electronic switch A, reaches for the button on traditional key board made in Great Britain with these electronic switches, and the present invention just can control 10 * K keyswitch.Because a switch has two ends, the one, go into end, the 2nd, go out end, when switch disconnected, the signal of going into end can't transmit and provide end, and the state of going into, go out two ends is just different.When switch closure, the signal of going into end can transmit and provide end, and the state that goes out end is just done identical variation with the state variation of going into end.Therefore, we can determine that a kind of logic gates realizes electronic switch A according to the logical relation of accusing switching line and gear control line.For example, be electronic switch A with one three input end AND circuit.Two input ends of this " with door " link to each other with the gear control line with the charge switching line respectively, and when the state of this two input end all was " 1 ", the state output terminal of this " with door " was just done identical variation with the state variation of the 3rd input end.Like this, this " with door " just constituted one is going out end and going into end of switch with output terminal and the 3rd input end, and first and second input ends are the electronic switch of control end.If an end of four gauge tap is all connected noble potential, the state of the other end of each gauge tap just can only have " 1 " and " 0 " these two so.We can form a tetrad with these four on off states, remove to control the data input pin of code translator F with it, for example control four--four data input ends of 16 line code translators.If with the output line of this code translator F as gear control line of the present invention, we just can control the gear control line by the different switch combination states of these four gauge tap (promptly keeping off control key) of control, remaining all is " 0 " (not necessarily four of retaining control key, it what can be decided by the line number of concrete gear control line and the condition that can control these gear control lines easily) for " 1 " to make its arbitrary.The utility model uses pin to control two groups of totally four keyswitches, and we can do the retaining control key with these four foot control keys (K21-K24).Thereby make hand of the present utility model, pin not come true from the dream that key just can be finished the function of conventional keyboard category-A key.

Category-B button (being K31-K33) needs to be used with the category-A button, should this it must be the button with respect to thirty years of age of category-A button.This just makes the utility model must open out-of-the-way several category-B key in addition.In the utility model, the category-B key makes under the grip and realizes its control function with the connecing together of the elastic switch that resets certainly of support plinth (4) contact jaw device with disconnection by the front and back push-and-pull of grip (1).Increase the category-B key if desired, also can utilize grip (1) about stir and increase by four gauge tap.More as the quantity of crossing the category-B key, we realize the category-B key at the same quadrat method of also available realization gear control line.

In fact, according to above imagination, also can remove to touch the several Control key by the dimensional orientation of foot control device or its pedal and do the category-B button; The category-B button also can be contained under the pedal of foot control device, and the operating key of gear control line is contained in and accuses that the key support down or the like.Because it is inessential that these keys by what form are gone to touch.As long as can touch them easily.

We are example with " four-way MS--2401 " type computer typewriter now, specifically narrate implementation method of the present utility model.

On the keyboard of this machine, the category-A key has 89; The category-B key has 5, wherein has two to be reusable, and in fact it has only 3, i.e. operating key, upper blocking key and keyboard commonly used.

We realize the category-A key first.Two grips are connected on the same base plate, and the relevant position of each finger is respectively loaded onto five and is touched button when holding on each grip, and this just has ten to accuse key.These ends of accusing key all are connected on the noble potential, and we just can obtain ten and accuse switching line so.When corresponding key was pressed, its state was " 1 ", otherwise was " 0 ".Because the category-A key has only 89, therefore, only need nine gear control lines just can satisfy the demand.We can make two foot control devices, just can obtain four switching lines.Form a tetrad circuit with these four switching lines.As crossing being first before the left-hand tread plate, after be second; Be the 3rd before the right-hand tread plate, after be the 4th.When both feet were set level, its state was 0000, and when left foot was pressed forward, its state was 0001.Through different sexadecimal code translator conversion, we just remove to control 16 gear control lines according to its different conditions.These four buttons just keep off control key.And on concrete " four-way MS--2401 " machine, only need nine gear control lines, and the state that therefore can select nine foot controls brakings the most favourable to do, they are 0000,0001,0010,0100,1000,1010,0101,1001,0110 these nine.Their corresponding sexadecimal numbers are respectively 0,1,4,8, A, 5,9,6.Therefore we only need to select 0,1,2,4,5,6,8,9 at the output terminal of code translator, A.These nine lines have been done the gear control line just.Remove to control 89 electronic switches that constitute by three input ends and door with these nine gear control lines and ten charge switching lines at last and remove to realize the category-A button.

On " four-way MS--2401 " machine three category-B keys are arranged, we can accuse under the key operating rod at two and respectively adorn a keyswitch, make to touch corresponding button and make it when certain operating rod pushes away forward and connect.Be understood that we can obtain two binary circuits again like this, and it there is one of four states: 00,01,10,11.Wherein we are used for conventional key-press status with state 00, and three remaining states can be respectively applied for and trigger the electronic switch that replaces upper blocking key, operating key and keyboard commonly used, thereby realize the category-B key.We only need with a simple decoding scheme three unconventional on off states to be grouped into three respectively by on two input ends and the electronic switch that constitutes for this reason, replace three category-B buttons with them.
