A kind of multiple layout keyboard
Technical field:
The present invention relates to a kind of computor-keyboard.
Background technology:
1874, many good fortune of Chris Xiao Er Si (Christopher Sholes) separated letter commonly used for the speed of the typewriting of slowing down, and to reduce typewriter extruding rate of breakdown between the trace when typewriting, had invented qwerty keyboard.1932, Bille August Dvorak (AugustDvorak) was invented Dovrak keyboard, for hope after not needing to avoid the extruding of trace, rearrange the key position, to improve typing speed.But people have been accustomed to qwerty keyboard, and Dovrak keyboard can't volume production.Afterwards, people also invented the keyboard of multiple different ordering forms, but all can not volume production because of people's use habit.
Summary of the invention:
The object of the present invention is to provide a kind of rational in infrastructurely, both can support to be accustomed to letter sequence input, again can be according to a kind of multiple layout keyboard of the order input of setting.
Technical solution of the present invention is:
A kind of multiple layout keyboard, comprise 26 English alphabet keys, it is characterized in that: be connected to the keyboard signal conversion equipment that the key letter conversion of signals that will sort by a kind of letter sequence mode becomes the alphabetic signal that sorts by another kind of letter sequence mode between 26 English alphabet keys signal output parts of keyboard and the host signal input end.
The keyboard signal conversion equipment is the keyboard signal transfer interpreter, is arranged between keyboard overall signal output terminal and the host signal input end, also is provided with the switch of whether selecting the keyboard transfer interpreter between keyboard overall signal output terminal and host signal input end.
The keyboard signal conversion equipment is one two tunnel 26 a bit multiplexed device; 26 English alphabet keys of keyboard, each key has two road button output terminals, wherein one road output terminal is to express a certain alphabet key output terminal that 26 letters are arranged according to a kind of lexicographic order, and another road output terminal is to express a certain alphabet key output terminal that 26 letters are arranged according to another kind of lexicographic order; Above-mentioned two road button output terminals are connected with one of two road input ends of above-mentioned two tunnel 26 bit multiplexed devices respectively, and two tunnel 26 bit multiplexed devices have one tunnel output terminal that is connected with the subsequent conditioning circuit input end, and two tunnel 26 bit multiplexed devices are connected with selector switch.Selector switch is high and low level selector switch.
The keyboard signal conversion equipment is an encoder circuit that is arranged in the keyboard circuit, is made up of a plurality of scramblers and multiplexer, comprise a multiplexer, the multi-channel input of multiplexer is connected with the output terminal of 26 letters of an expression according to the scrambler of different set letter arrangement mode respectively, the input end of each scrambler all is connected with keyswitch matrix in the keyswitch circuit, and multiplexer is connected with selector switch.
26 English alphabet key surfaces of keyboard are equipped with two different alphabetic flags, and one of them is a certain alphabetic flag of arranging according to a kind of lexicographic order, and another is a certain alphabetic flag of arranging according to another kind of lexicographic order.
The present invention is rational in infrastructure, by selector switch, both can be according to custom letter sequence (or need ordering form) input, and again can be according to inputs in proper order such as A~Z, or according to other setting forms inputs.Make the user who gets used to existing keyboard not change input habit and use, also can make new scholar, according to the input easily and fast of orders such as A~Z.

Embodiment:
Embodiment 1:
A kind of novel multiple layout keyboard, comprise 26 English alphabet keys, 26 English alphabet keys of keyboard, each key has two road button output terminals, wherein one road output terminal is to express 26 letters according to the tactic a certain alphabet key output terminal of A~Z, and another road output terminal is to express 26 letters a certain alphabet key output terminal of series arrangement (routine QWERTY form or other forms that needs) as required; Above-mentioned two road button output terminals are connected with two road input ends 1,2 of one two tunnel 26 bit multiplexed device 3 (claiming MUX again) respectively, two tunnel 26 bit multiplexed devices have one tunnel output terminal 4 that is connected with the subsequent conditioning circuit input end, and two tunnel 26 bit multiplexed devices are connected with high and low level selector switch 5 (S1).When S1 and low level () when linking to each other, MUX selects input channel 0, keyboard works in classical layout pattern (being equal to common keyboard); When S1 and high level (VDD) when linking to each other, MUX selects input channel 1, and keyboard works in new layout pattern (promptly A~Z natural order layout pattern pressed in letter).
Embodiment 2:
A kind of novel multiple layout keyboard, comprise 26 English alphabet keys, the key letter conversion of signals that is connected to ordering on demand between 26 English alphabet keys signal output parts of keyboard and the host signal input end becomes the keyboard signal conversion equipment by another alphabetic signal that sorts corresponding to another kind.The keyboard signal conversion equipment is a keyboard signal transfer interpreter 6, be arranged between keyboard overall signal output terminal 8 and the host signal input end 9, between keyboard overall signal output terminal and host signal input end, also be provided with the switch 7 (S2) of whether selecting the keyboard transfer interpreter.
Embodiment 3:
A kind of novel multiple layout keyboard, comprise 26 English alphabet keys, be connected to the keyboard signal conversion equipment that the key letter conversion of signals that will sort by a kind of letter sequence mode becomes the alphabetic signal that sorts by another kind of letter sequence mode between 26 English alphabet keys signal output parts of keyboard and the host signal input end.The keyboard signal conversion equipment is one and is arranged in the keyboard circuit, the encoder circuit of forming by a plurality of scramblers and multiplexer, comprise a multiplexer 10, two road input ends of multiplexer 10 respectively with a scrambler 11 of expressing 26 letters according to different set letter arrangement mode, it (is that scrambler 11 is expressed 26 letters according to the alphabetical arrangement mode of a kind of setting that 12 output terminal connects, scrambler 12 is expressed 26 letters and is set alphabetical arrangement mode according to another kind), scrambler 11,12 input end all is connected with keyswitch matrix in the keyswitch circuit, and multiplexer is connected with selector switch 13 (S3).What present embodiment adopted is the single coding of Fairchild MM74C922 (16 key) integrated circuit.Certainly, also can adopt other forms of scrambler integrated circuit, only need scrambler is changed the circuit in the frame of broken lines among Fig. 5, can realize the function of multiple layout keyboard.
26 English alphabet key surfaces of the keyboard of embodiment 1~3 are equipped with two different alphabetic flags, one of them is a certain alphabetic flag that needs series arrangement (the QWERTY forms that example is classical) according to a kind of, and another is 26 letters need series arrangement (orders of routine A~zee order or other needs) according to another kind an a certain alphabetic flag.
