Abstract

The utility model relates to an improved keyboard with a path rocker bar, characterized in that the space key of the known keyboard is provided with one path rocker bar. The path rocker bar is connected with a circuit board and can be separately provided with the space key for the control of a thumb. The space key can be divided into two units, and the path rocker bar is positioned between the units of the space key. A left executive key and a right executive key can be arranged on both sides of the space key.

Description

Improvement keyboard with track rocking bar

Computing machine is the instrument of popularizing the most on data processing at present, because that it has speed is fast and store all advantages very easily of computational data, so can substitute manually-operated effectively, makes efficient increase substantially.

And the input mode of computing machine, the most general is exactly keyboard, and its reason is owing to keyboard is that the continuity typewriter comes, so for having typewriting experience person, be converted to keyboard operation, there is no too big obstacle, even is to drive a light carriage on a familiar road.

Yet along with after window software (WINDOWS) is in fashion, mouse becomes another kind of important input media, and it is very convenient, but its shortcoming is the space outerpace that it need move.So in order to save the operating space, the portable computing machine is to replace mouse with trace ball, and trace ball is inserted in the portable computing machine, do not needed computing machine mobile space in addition with finger manipulation.

But the shortcoming of this mode is trace ball and must occupies a part of space of taking the type computing machine, this is for pursuing light, thin, short, little portable computing machine, often cause the difficult problem on the spatial configuration, and because of it makes progress for sphere, so become easily infected by dust, make its malfunction, so need be diligent in cleaning or wiping.Therefore, there is trace ball rocking bar (Joystick) to be developed by present technique field personnel.

And the present track rocking bar of habitually practising, as shown in Figure 1, be that rocking bar is arranged between G, H, B three keyboards, and brandish with the forefinger of left hand and right hand, treat that cursor is behind mobile a period of time location, again by upper and lower two execute keys, finish similar mouse function, common this operation is to hocket with typewriting.

All have the typewriting experience and all know, correct typewriting method be left forefinger at the F key, RIF is at the J key.So, when if forefinger moves apart F, J key with control track rocking bar, then often cause the wrong of typewriting or reduce typing speed, simultaneously, forefinger is in the typewriting operation, be the most arduous, because the keyboard around it all relies on forefinger, so add the track rocking bar, its working load is overweight, certainly, its obtainable effect is also therefore had a greatly reduced quality.

On the other hand, in the typewriting operation, the finger load is the lightest, surely belongs to thumb, and its scope of work is the narrowest, and only responsible space bar (SPACE BAR) reaches up and down and moves in the execute key, so, with the viewpoint opinion of ergonomics, keyboard commonly used and the configuration of track rocking bar, and imperfect.

The purpose of this utility model provides a kind of improvement key with track rocking bar.

The structure of the utility model keyboard is:

In the middle of the space bar of known keyboard, a track rocking bar is set, this track rocking bar is linked on the circuit board, and with the discrete setting of space bar, can control for thumb.

Space bar also may be partitioned into two unit, and the track rocking bar places between Unit two of this space bar.

On this keyboard, also left and right sides execute key can be set in the space bar both sides.

For further specifying concrete technology contents of the present utility model, see also accompanying drawing:

Fig. 1 is the known keyboard synoptic diagram with track rocking bar;

Fig. 2 is a synoptic diagram of the present utility model;

Fig. 3 is a cut-open view of the present utility model;

Fig. 4 is another embodiment synoptic diagram of the utility model;

Fig. 5 is the cut-open view of the space bar part of Fig. 4.

As shown in the figure, basically, the utility model is to hollow out and put a track rocking bar 2 in the stage casing of space bar 1, and left execute key 3 and right execute key 4 will also be set in keyboard.

Wherein, the stage casing of this space bar 1 hollows out and forms a keyhole 11, and also thereupon being shifted simultaneously with space bar circuit and the excellent key 12 that contact with it of its below, so space bar 1 still has identical effect and effect in input operation.

Track rocking bar 2 passed through aforementioned excellent hole 11 and was linked to contact on the circuit board, so before and after it or when rocking from side to side, produce X-axis and the resistance value of Y-axis or the variation of capacitance, thereby reach computing machine to change the cursor position (this point is a known technology) of display.

A left side execute key 3 and right execute key 4 be on the computer body of being located at outside the keyboard in occasion commonly used, but the utility model are located at the left and right side of space bar 1 with it, and can be all thumb and control.

Fig. 4 controls another set-up mode under the scope for track rocking bar 2 of the present utility model in thumb, that is is placed between two space bars of cutting apart 1, and two space bars 1 link with circuit respectively, so so also can reach identical effect.

Therefore, through enforcement of the present utility model, control and do not influence the typewriting operation of forefinger except that track rocking bar and left and right execute key are thumb, also, left and right execute key exempts the shortcoming of being located in addition on the body that expends cost in the keyboard owing to can being arranged at, so for the portable computing machine, because of not opening the identical effect that the space has trace ball in addition.

The disclosed just preferred embodiment of the utility model a kind of allly comes from technological thought of the present utility model and is that the change that personnel were easy to know by inference of skilled this technology can be modified, and all do not break away from patent protection category of the present utility model.

Claims

1. the improvement keyboard with track rocking bar is characterized in that in the middle of the space bar of keyboard, and a track rocking bar is set, and this track rocking bar is linked on the circuit board, and with the discrete setting of space bar, can control for thumb.

2. the improvement keyboard with track rocking bar as claimed in claim 1 it is characterized in that space bar wherein is divided into Unit two, and the track rocking bar places between Unit two of this space bar.
