During corresponding previous mode I to pattern V, output signal 902 is maintained when the button of mouse apparatus 9 does not have action
One high levle voltage V2, until processing unit 90 detects input signal 901 by pattern II and maintains a preset time Δ Ts
Voltage 0 after, output signal 902 is just driven to be changed into low level voltage 0 from high levle voltage V2, and continue low level voltage 0；
It changes into pattern V until processing unit 90 detects 901 slave pattern IV of input signal and maintains the voltage V1 of preset time Δ Ts
Afterwards, output signal 902 is just driven to be changed into high levle voltage V2 from low level voltage 0.
After mouse apparatus 9 sends out output signal 902 to electronic device 8, electronic device 8 can be again according to output signal
902 in " voltage V2 → voltage 0 " be determined as by key pressing and according to output signal 902 in " 0 → voltage of voltage V2 " is determined as
Button is decontroled.
Through aforementioned measured result, the missing of existing machinery formula button is：The quality of mechanical key differs, and sensitivity is not
Good mechanical key easily causes the increase of the unsteady state time such as Fig. 2A so that the reaction time can also increase.It is special
It is not in many game for needing real time reaction, by taking shooting game as an example, it is possible to, originally should be by the delay of this period
Oneself flashes bullet to the target shot, and the delay for how allowing this period reduces to minimum, is the subject for needing to solve.

Refering to Fig. 4 A, 4B, and coordinate Fig. 3, mechanical key 11 is generating the input signal of a supply processing unit 10
101, processing unit 10 receives input signal 101 and application program of the output signal 102 to host 3 is exported after being judged
31, application program 31 is enabled to be encoded according to the state of output signal 102.
When the mechanical key 11 of input equipment 100 does not have action, input signal 101 is to maintain in pattern I and pattern V
The voltage V1 of one first stable state.The time point Ts of the time point Tp that is pressed when the mechanical key 11 of input equipment 100 and relieving, it is defeated
The voltage for entering signal 101 generates variation, and state includes：Pattern II be the short time unsteady state concussion voltage,
The voltage 0 and the concussion voltage in the unsteady state that pattern IV is the short time that pattern III is one second stable state；Wherein, it shakes
The occurrence cause for swinging voltage is because caused by the mechanical force of mechanical key.
Duration timing of the processing unit 10 to the voltage V1 of the first stable state, when input signal 101 because mechanical force starts
When generating the unsteady state to swing above and below the amplitude such as section II, if processing unit 10 has judged the duration of the first stable state
The output signal that behavior is pressed in a representative is then generated more than a first time interval Δ Ts1.In the present embodiment, behavior is pressed in representative
Output signal be " voltage V2 → voltage 0 ".
Then, duration timing of the processing unit 10 to the voltage 0 of the second stable state；When input signal 101 is because of mechanical force
When generating the unsteady state to swing above and below the amplitude of a period of time, processing unit 10 judges that the duration of the second stable state has surpassed
It crosses one second time interval Δ Ts2 and then generates the output signal that behavior is decontroled in a representative.In the present embodiment, relieving behavior is represented
Output signal is " 0 → voltage of voltage V2 ".
Refering to Fig. 5, and coordinate Fig. 3 and Fig. 4 A, 4B, the preferred embodiment of the triggering judgment method of mechanical key of the present invention

Stablize a predetermined time T (step 402)Judge input signal 101 be maintained at the first stable state or the second stable state time whether
Reached predetermined time T, in this preferred embodiment, first time interval Δ Ts1 and the second time interval Δ Ts2 it is identical and equal to should
Therefore predetermined time T, if being less than predetermined time T, is failure to actuate；If more than predetermined time T, then the judgement input letter that continues
Whether numbers 101 change (step 403)It generates to represent for the first stable state if changing, before according to input signal 101 changing and press
Under output signal 102, according to input signal 101 change before for the second stable state generate represent decontrol 102 (step of output signal
404)。
It remarks additionally herein, the concrete scheme of the triggering judgment method of mechanical key of the present invention with hardware in addition to being patrolled
It collects circuit realization or computer software is realized, realize that the device of computer software includes：To first stable state non-steady
Determine the module of the duration timing before state；It responds above and below the amplitude for generating a period of time because of mechanical force to the input signal
The unsteady state to swing is to judge duration of first stable state before unsteady state more than a first time area
Between then generate the module that the output signal of behavior is pressed in a representative；To the module of the duration timing of second stable state；And it rings
The input signal is coped with because of the unsteady state to swing above and below the amplitude of mechanical force generation a period of time to judge second stable state
Duration before unsteady state has then generated the output signal of representative relieving behavior more than one second time interval
Module.The scope that the present invention protects is belonged to above.
After the application program 31 of host 3 receives output signal 102, for the application program 31 of the coding of keyboard
For, the scan code (ScanCode) of each button, which has, uniquely to be pressed coding (make code) and uniquely terminates to compile
Code (break code), therefore, when pushing button a, application program 31 is notified according to the output signal 102 for representing behavior of pressing
And generate a correspondence button a presses coding " 1e "；When decontroling button a, application program 31 is according to representing the defeated of relieving behavior
Go out the end coding that signal 102 notifies and generates a correspondence button a " 61 ".However, such application mode be only a kind of example and
Unrestricted, the usual operator in this field also belongs to the present invention when that can be changed for the similar application technology of application program 31
Scope.In addition, the usual skill in this field, which can also apply that inventive concept to one, includes multiple mechanical keys 11
Keyboard or mouse are not limitation with a mechanical key 11.
In conclusion the effect of present invention, is：Processing unit 10 is in advance before unsteady state for stable state
During carry out timing, therefore, as long as detecting stable state changes into unstable state, will react action immediately, avoid ineffective
Quick mechanical key needs to wait for just reacting after unsteady state time and the time of steady state time the prolonging of action
