CN2754150Y - Three-key parellel-impact keyboard device - Google Patents

Abstract

The utility model relates to a three-key parallel-impact keyboard device, which is composed of a keyboard shell body, a key set, a key elastic body, a printed circuit of a film board, a keyboard controller, etc. The key set is composed of a typing key area, a function key area, an editing key area, etc. The middle part of the lower part of the typing key area is respectively provided with a forward key and an inverse key from center to left and right sides. Both outer sides are respectively provided with one space key. A thumb of a left hand or a right hand is used to touch the forward key or the inverse key and two letter keys are simultaneously stroked by two fingers. Two letters orderly arranged according to the symbol of the forward key or the inverse key are inputted to a computer applying software system by the proper software treatment of the computer. The letter inputting time of striking the keys is shortened.

Description

The key board unit that is used for triple bond and hits

Technical field

The invention belongs to the keyboard portion of general computer keyboard device or notebook computer is carried out improved technical scheme.

Background technology

The disclosed key board unit that is used for the many key click input, the key board unit that is used for the input of multikey concurrent beating type high speed Chinese character as disclosed 94105226.5 applications for a patent for invention, left and right 12 keys are set respectively symmetrically, different fully with the keyboard portion of the general computer keyboard of current trend and notebook computer, the numerical key, function key, the editing key that do not have apportion again cause the user to be difficult for grasping and use.

Goal of the invention

Purpose of the present invention proposes a kind of user and grasps use easily, and can triple bond and hit the key board unit of two Latin alphabets realizing that disposable input is arranged according to predesigned order.

Summary of the invention

When two letter keys also hit input, the input information of computing machine actual reception have two kinds may, a kind of may, the formerly alphabetical second of alphabetical first after, another kind of may, the formerly alphabetical first of alphabetical second after.Will be under two letters and the situation of hitting, realize two letters that input is unique according to the predesigned order arrangement, must increase and hit a key, it can produce the marking signal of two alphabetical orderings, through the suitable processing of corresponding software, realize triple bond on computers and hit two letters that disposable input is arranged according to predesigned order.The sign key has two kinds, and sign is with two alphabetical orderings hitting: sign with the little letter of alphabet sequence number preceding, alphabet sequence number big letter after order arrange, for example: AC arranges, and is referred to as cis sign key, is called for short along key; Sign with the big letter of alphabet sequence number preceding, alphabet sequence number little letter after order arrange, for example: CA arranges, and is referred to as contrary formula sign key, is called for short contrary key.

The present invention is as the computer keyboard device of the keyboard portion of desktop computer keyboards or notebook computer, by keyboard case, key groups, the button elastic body, film printing wiring board group and form by the keyboard controller of integrated circuit control, keyboard controller is connected with the computer host system plate, keyboard controller is connecting the thin web printed wire, the thin web printed wire is provided with the node corresponding circuit at each button key position lower position, when pressing any one button, the thin web printed wire will produce electric signal, by keyboard controller, to host computer system send one group with button key face identify corresponding coordinate figure binary code; The keyboard group is made up of typewriting keypad, function key area, editor's keypad etc., in the middle of typewriting keypad bottom, originally QWERTY keyboard is provided with the position of rectangular space bar, after removing rectangular space bar, by between two parties, on the left side is provided with along key, and contrary key is set on the right, along the key and contrary excentric two outsides of key two keys, a space bar is set respectively again.Keyboard layout's structural representation of key board unit of the present invention as shown in Figure 1 and Figure 2.Be arranged on the left side along key among the figure, contrary key is arranged on the right; Another scheme, be arranged on the right along key, contrary key is arranged on the left side;

The button of key board unit of the present invention is except that the suitable key that increases newly, contrary key, other each character keys, comprise two space bars suitable and contrary key two outsides, the node circuit that identifies corresponding thin web printed wire with button key face all is set below, the electric signal that when pressing character keys down in working order, produces, by keyboard controller, send one group of corresponding coordinate figure binary code to host computer system; The node circuit of the thin web printed wire that suitable key, contrary key are provided with below has multiple scheme:

One of scheme is being provided with the node circuit of thin web printed wire that can produce the binary code of two kinds of corresponding coordinate figures of non-standard button key face by keyboard controller respectively below key, contrary key; Adopt this scheme, the starting software of keyboard will increase corresponding new content;

Two of scheme, in the typewriting keypad of computer standard keyboard, "; " semi-colon key, " ' " single quotation marks key, "/" left slash key, “ " eight kinds of character keys such as right slash key, " [" left square bracket key, "] " right-hand bracket key, "-" single whippletree key, "=" two whippletree keys are the keys that are of little use; therefrom select two character keys arbitrarily; the corresponding two kinds of node circuits of thin web printing route that can produce the binary code of corresponding coordinate figure by keyboard controller these selected two keys are separately positioned on along the position of key below contrary key;

The scheme of a reality, node circuit with " node circuit of the corresponding thin web printed wire of [" left square bracket key is arranged on along the position below the key, with "] " corresponding thin web printed wire of right-hand bracket key is arranged on position below the key; Perhaps, the node circuit with " node circuit of the corresponding thin web printed wire of [" left square bracket key is arranged on the position below the contrary key, with "] " corresponding thin web printed wire of right-hand bracket key is arranged on position below the suitable key;

Useful effect

Use key board unit of the present invention, import two different when alphabetical, can hit with a thumb of the left hand or the right hand along key or contrary key (hitting of two alphabetical cis arrangements along key, what contrary formula was arranged hits against key), two fingers in four fingers of other of two hands are with hitting this two letter keys, just can produce the binary code of three corresponding character coordinates values, the suitable software processes of machine as calculated, the computer application software systems are equal to and have imported two letters arranging according to the order of suitable key that hits or contrary key sign; When importing two same letter, two kinds of methods are arranged, a kind of this letter key of method double hit, another kind method, left hand and right hand thumb with hitting along key and contrary key, are hit this letter key together with a finger respectively again, also produce the binary code of three respective coordinate value, the suitable software processes of machine as calculated, the computer application software systems, be equal to imported two should letter; Like this, just realized triple bond and hit that two letters that disposable input is arranged according to predesigned order so just can shorten the time that keystroke is imported greatly, be specially adapted to code length and be 4 various Chinese characters, the coding input of word coded input method, with secondary and hit Chinese character of quick typing or word.Because key board unit of the present invention, just on the keyboard portion of existing general QWERTY keyboard or notebook computer, improve, it is very little to use the operation fingering of keyboard to change, and helps the user and grasps use.
