Because the inventive method input generation symbol only needs by next key sometimes, and need press a plurality of keys simultaneously sometimes.But; pressing a plurality of keys simultaneously is to be difficult to realize; promptly when a plurality of keys are pressed; usually have have earlier after; be pressed in all keys that need press all are pressed this section process from first key; the key that is pressed can be formed multiple invalid key combination, must have certain measure to differentiate, and could guarantee that the output encoder of the invalid key combination in this process is not utilized.Equally, after a plurality of keys are pressed, discharge simultaneously also is to be difficult to realize, be pressed the back in whole keys are released this section process at a plurality of keys, the key that is pressed can be formed multiple invalid key combination, also must there be certain measure to differentiate, be utilized with the output encoder that guarantees the invalid key combination in this process.For this reason, the present invention adopts the electronics arbiter that the validity of output encoder is differentiated, and electronics arbiter and keyboard are formed finger-impu system.Fig. 4 is an electronics arbiter block scheme, and it is made of jointly button 8, static coding device 9, status code register 10, output code register 11.Its principle of work is: when pressing one or more key, static coding device 9 obtains the code of button, and this code is 7 bit binary number, each corresponding key, when key was not pressed, the corresponding bit digital of code was " 0 ", when key was pressed, the corresponding bit digital of code was " 1 ".In this section process, because finger can not as one man be pressed required key simultaneously, some invalid combination button states will occur before a plurality of keys are depressed to the effective assembled state of composition, arbiter can carry out distinguishing validity.Its differentiation process is: when not having key to be pressed, status register 10 is reset, and each bit digital is " 0 " in the output code of static coding device 9, and the numerical value of code also is " 0 ".As long as there is a key to be pressed, just with status register 10 set, behind the code of static coding device 9 each acquisition buttons, if the numerical value of the output encoder of the numerical value 〉=output code register 11 of this code is then sent this code into output code register 11; If each bit digital is " 0 " in the output code of static coding device 9, and status register 10 set, then at this moment the output encoder of output code register 11 is exactly effective alphabetic coding (this coding criteria of right and wrong), it can be exported to robot calculator or other electronic installation, after the output status register 10 and output code register 11 be resetted.Fig. 5 is electronics arbiter circuit theory diagrams, and its simple principle of work is: K 1～K 7It is respectively button 1～7; Resistance R 1～R 7Power supply short circuit after avoiding key to be pressed; Capacitor C 1～C 7, resistance R 8～R 14With integration member IC 1, IC 2The not gate of middle band application schmitt trigger is formed the static coding device 9 that can eliminate key jitter; Integration member IC 3～IC 5And 1/2 IC 6The common output code register 11 of forming; In addition, 1/2 IC 6And IC 7～IC 10Form status register 10; Resistance R 15And capacitor C 8Form delay circuit, be used for the automatic reset signal that produces of alphabetic coding output back time-delay a period of time, status register 10 and output code register 11 are resetted.Its mutual connection relationship is: button 1～7 passes through resistance R respectively 8～R 14With IC 1Input end 13,11,9,5,3,1 and IC 2Input end 13 be connected IC 1Output terminal 12,10,8,6,4,2 and IC 2Output terminal 12, on the one hand respectively with IC 3, IC 4, IC 5Input end 13,1 and IC 6Input end 13 be connected, on the other hand respectively with IC 7Input end 1,2,4,5,13,12,10,9 be connected IC 3, IC 4, IC 5Output terminal 12,8 and 6,2 and IC 6Output terminal 12, the non-standard coding of 8(out alphabet) be connected IC with the Data Input Interface of computing machine or electronic installation 6Output terminal 6,2 and IC 10Input end 1 be connected IC 7Output terminal 3,6,8,11 respectively with IC 8Input end 2,1,13,12 be connected IC 8Output terminal 8 and IC 6, IC 9Input end 1 be connected IC 9Output terminal 2 and IC 10Input end 2 be connected IC 3～IC 6Input end 5,9 be in parallel after, pass through on the one hand resistance R 15With IC 10Output terminal 3 be connected, pass through C on the other hand 8Ground connection.IC 10Output terminal 3(when being output as " 1 ", expression D 1～D 7The alphabetic coding of forming is effective, can be for utilizing; When being output as " O ", expression D 1～D 7The alphabetic coding of forming is invalid, can not be utilized) be connected with input request (as the interrupt request) operation circuit of computing machine or electronic installation.
The logical relation synoptic diagram that refers again to arbiter circuit shown in Figure 6 below further describes its principle of work, and below all to adopt noble potential be " 1 ", and electronegative potential describes for the positive logic of " 0 ".Among Fig. 6, IC 1, IC 2Not gate by the band application schmitt trigger is formed, they and C 1～C 7, R 8～R 14Form static coding device 9, and can eliminate the shake that produces when pushing button, it exports B 1～B 7Be transported to IC respectively 3～IC 7Input end; IC 3～IC 6Formed and formed the R-S trigger by external cabling by rejection gate, it exports D 1～D 7The non-standard coding of forming letter, IC 7, IC 8By or door forms, it is exported E and is connected respectively to IC 6And IC 9Input end, IC 9Be a not gate, it exports B 8And IC 6Output D 8Be transported to IC together 10Input end, IC 10Be one and door, its output F represents the alphabetic coding D of output code register 11 outputs 1～D 7Whether effective.When its output F is " 1 ", expression D 1～D 7The coding of forming is effective, can be for utilizing; When its output F is " 0 ", expression D 1～D 7The coding of forming is invalid, can not be utilized.Below respectively by a key with by two kinds of situations of a plurality of key letters of input its principle of work to be described: (one) is by the situation of a letter of a key input.After circuit is connected, when key all is not pressed, should be with the zero clearing of whole R-S trigger.When any key is pressed, K for example 3Key is pressed, output B 3Be " 1 " output D 3Become " 1 ", and output B 1～B 2, B 4～B 7Still be " 0 " output D 1～D 2, D 4～D 7Also be " 0 ", output E is " 1 ", output D 8Become " 1 ", output B 8Be " 0 ", then export F and be " 0 ".At this moment expression exports D 1～D 7The generation symbol coding of forming is invalid.When key is pressed and be released, output B 1～B 7Be " 0 ", output E is " 0 ", output B 8Be " 1 ".Because capacitor C 8Both end voltage can not be suddenlyd change, so A point current potential still keeps " 0 ", so D 1～D 7It is constant to maintain the original state, D 8Still remain " 1 ", output F becomes " 1 ", expression output D 1～D 7The coding of forming is effective, can be utilized.This state will be maintained to C 8Charging to A point current potential reaches till " 1 ".When A point current potential is " 1 ", D 1～D 8All become " 0 ", output F becomes " 0 ", expression output D 1～D 7The coding of forming is invalid, can not be utilized.Till this state will remain to when pushing button next time.Other any keys be pressed the input letter situation all similar to the situation of above-mentioned explanation; (2) press the situation that a plurality of keys are just imported a letter.In fact strict, a plurality of keys are pressed, always have after having earlier, situation after first key is pressed is identical with the situation of a letter of front singly-bound input, and promptly the not gate that links to each other with this key is output as " 1 ", and corresponding R～S trigger is output as " 1 ", the not gate output that links to each other with other key is " 0 ", the R of their correspondences～output of S trigger also is " 0 ", and output E is " 1 ", output D
