Abstract

The utility model relates to a combined keyboard for inputting characters, which arranges the key region according to the combined mode of a plurality of keys. The combination of symbolic keys is synchronously pressed down to generate coding. Because the combined input mode of the symbolic keys is adopted, the key numbers and the volume of the keyboard are reduced. The combined keyboard for inputting characters can be operated by a single hand; the combined keyboard for inputting characters is provided with the mouse function, the production cost is reduced, the work efficiency of operators is enhanced, and the operating environment is improved. The combined keyboard for inputting characters can completely replace and be compatible with the standard keyboards of computers, typewriters, etc.

Description

Combined keyboard

The present invention relates to a kind of integral keyboard of character input.Form by key array, key scanning circuit and processor controls.

Each coding of output during work of existing keyboard, all corresponding to a symbolic key, the perhaps result that moves of symbolic key and function key combination, the scan code Be Controlled processor that is produced is converted into output code, delivers to output interface.Has only a few functions key, for example: ctre, shift, Aef, 2nF, 1N Deng can making up, and can not make up action as symbolic key with symbolic key.Therefore need the symbolic key of some inevitably, make its keyboard volume bigger, production cost is higher, and the efficient and the environment for use of operation is affected.

Purpose of the present invention is exactly in order to overcome the deficiency of above-mentioned prior art, and provides a kind of bond number and volume to reduce greatly, reduces production costs, and improves operator's work efficiency and improves the integral keyboard of environment for use.

The objective of the invention is to realize: convenient according to finger manipulation by following measure, keyboard is divided into several keypads according to several symbolic key array modes, each output encoder, be to produce by several key combinations, be to make up between several symbolic keys or between symbolic key and the function key, press the back output encoder synchronously.Symbolic key is participated in combination like this, can realize a large amount of symbolic codings with less key.For example, get 5 following key combinations in 20 keys, can produce Q=in theory

=21699 kinds of codings.

Purpose of the present invention can also be realized by following mode: keys all on the keyboard is divided into 6 keypads, and wherein the A keypad is 3 keys, is operated by thumb; The B keypad is 4 keys, is operated by forefinger; The C keypad is 3 keys, is operated by middle finger; The D keypad is 3 keys, is operated by the third finger; The E keypad is 4 keys, is operated by little finger of toe; The F keypad is 4 keys, does not specify special finger manipulation.Therefore above-mentioned 6 keypads can carry out combination in any, during actual act, each effective Macintosh is in the process of pressing or lifting, will some other invalid combination key appears randomly, the method that processor controls is differentiated the validity of Macintosh is as follows: in the adjacent a collection of scan code in front and back, it is maximum to comprise the combination bond number, and the scan code that repeats in the secondary continuous sweep at least is the effective scanning sign indicating number.In order to realize this method of discrimination, processor controls comprises 6, one arbiters 7 of 5, one flag registers of 4, one differentiation registers of a scan code register.Wherein flag register 6 has two set of landmarks 6-1,6-2 at least.New each time scan code K ₄Be placed in the register 4, if K ₄Greater than the K in the register 5 ₅, i.e. K ₄＞K ₅, then content load register 5 in the register 4, and the zone bit 6-2 set of flag register 6; If K ₄=K ₅, then the zone bit 6-1 set of register 6; If K ₄＜K ₅, then the checkmark register 6, when zone bit 6-1, the equal set of 6-2, so scan code is an effective code in the register 5, are converted to coding output immediately, and clear 6-1,6-2.When the arbitrary not set of zone bit 6-1,6-2, then in the coding load register 5 in the register 4, clear 6-1 or 6-2.

The present invention can also increase mouse control key and trace pulse generator, is used as Genius mouse and uses.When pressing the mouse control key, handle trace pulse, and the generation cursor control signal is sent to output interface.

The keyboard root position has the back cushion of a projection, and rough surface is arranged on it.

Description of drawings of the present invention is as follows:

Fig. 1 is the schematic diagram of integral keyboard.

Fig. 2 is the vertical view of standard combination keyboard.

Fig. 3 is a band mouse combination keyboard side view.

Fig. 4 is a band mouse combination keyboard vertical view.

Fig. 5 is the table of comparisons of key combination and symbol.

Below in conjunction with accompanying drawing the present invention is described in further detail: as shown in Figure 1, inner structure comprises key array 1, key scanning circuit 2, processor controls 3.Processor controls 3 comprises 5, one flag registers 6 of 4, one differentiation registers of a scan register, and flag register 6 is provided with zone bit 6-1 and 6-2, also has an arbiter 7 in addition.As shown in Figure 2, the keyboard root has the back cushion 8 of a projection, and integral keyboard conveniently is divided into 6 keypads according to one-handed performance, and the A keypad has A ₁, A ₂, A ₃Key, by thumb operation, the B keypad has B ₀, B ₁, B ₂, B ₃Key, by the forefinger operation, the C keypad has C ₁, C ₂, C ₃Key, by the middle finger operation, the D keypad has D ₁, D ₂, D ₃Key, by third finger operation, the E keypad has E ₀, E ₁, E ₂, E ₃Key, by the little finger of toe operation, the F keypad has F ₀, F ₁, F ₂, F ₃Key is not specified special finger.Operating key: B wherein ₀=SPACE(space), E ₀=ENTER(carriage return), F ₀=↑, F ₁=→, F ₂=↓, F ₃=←, A ₁=SHIFT, A ₂=ctre, A ₃=Aet.The table of comparisons of key combination and symbol is seen Fig. 5, and the left side one column of figure represents that finger institute is expert in the table.For example: the key combination on 1 expression, the first line unit dish.1-2 represents to intersect row combination, and C, D, E are first row, and B is second row, during C, D, three key combinations of E here, all on delegation, gets rid of the combination of C, D, E different rows.The then desirable different rows of B and C, D, E.Again for example: 3-1 refers to the B of C, D, E and first row of the third line ₁Key is combined, and the BDE among the 3-1 is B ₁-D ₃-E ₃The combination of key.

Fig. 3 and Fig. 4 have represented a kind of one-handed keyboard that has Genius mouse, have comprised

mouse control key

9 and 10, tracking ball 11, singlehanded standard key disk body.So singlehanded QWERTY keyboard and Genius mouse are combined in same shell.This Keyboard Control processor has two kinds of functions, does the Genius mouse time spent, handles trace pulse, and is converted into cursor control signal and is sent to output interface.Do the keyboard time spent, handle the key scanning sign indicating number, and be converted into the significant character coding and be sent to output interface.Because this embodiment has realized QWERTY keyboard and two kinds of functions of Genius mouse, hand of user does not leave keyboard and just can finish computer graphics, full-screen editing, and control etc. are operation all.

The present invention compared with prior art owing to adopt the combined symbols number key, reduces bond number and volume greatly, has reduced production cost, has bigger meaning for the raising of operator's operating efficiency and the improvement of operation environment for use.
