The technical scheme of dealing with problems that the utility model proposes is: described a kind of 19 key combination formula keyboards, formed by external data line, pilot lamp, power pack, shell, keypad, and it is characterized in that: keypad is arranged on above shell; The bottom of shell arranges power pack; 19 conventional mechanical buttons are set on keypad; Pilot lamp is installed on the indicator lamp hole that is arranged in upper casing top; The external data line directly is linked on keypad.

Described a kind of 19 key combination formula keyboards are comprised of external data line, pilot lamp, power pack, shell, keypad, and it is characterized in that: the external data line can be USB port, PS/2 interface and wave point.

The invention has the beneficial effects as follows: not only can utilize the nineteen button just can be combined into 101 computor-keyboards of standard, and also simple in structure small and exquisite, the convenient use.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further detailed.

Fig. 1 is 19 key combination formula keyboard schematic diagram; Fig. 2 is the upward view of Fig. 1.

Wherein, 1. pilot lamp; 2. shell; 3. keypad; 4. mechanical key; 5. external data line; 6. power pack.

Embodiment

As shown in Figure 1, a kind of 19 key combination formula keyboards, keypad 3 are arranged on shell 2 tops; The bottom of shell 2 arranges power pack 6; 19 conventional mechanical buttons 4 are set on keypad 3; Pilot lamp 1 is installed on the indicator lamp hole that is arranged in shell 2 tops; External data line 5 directly is linked on keypad 3.

Its concrete course of work is as follows: the top is labeled with Num, Caps, F, Scroll printed words places, is respectively four functional indicator lights of keyboard.When keyboard connected energising, four lamps extinguished after bright one second entirely, and expression enters normal operating conditions.At this moment, keyboard is in the function input state, and above button, function shown in the second style of writing word is opened.F11 in Fig. 1 and F12 are not function key, and this moment, F11 was the upper key of directionkeys, and F12 is space bar.During this state, pin simultaneously Shift and numerical key, input the F function key.

If click shift key, the Num lamp is bright, enters the word input state.Directly press numerical key to computer input numeral, namely the first row left side numeral on button, pin Shift and press numerical key again, incoming symbol, i.e. the first row right side symbol on button.A bottom row's left button ←, lower key ↓ and right button →, but coordinate numerical key input alphabet or symbol this moment, they distinguish three letters or the symbol of the third line on corresponding button.

Click shift key, the Caps lamp is bright again, and other lamp goes out entirely, and is almost identical when the input function of this moment and Num lamp are bright, and difference is that the letter of input is capitalization.Again click shift key, Caps lamp and Num lamp go out entirely.

If click Ctrl, the F pilot lamp is bright, and other lamp goes out entirely, and the F function key of keyboard is opened.Click Ctrl, the Scroll lamp is bright again, and other lamp goes out entirely.This moment keyboard or function key state, entirely going out different from four lamps is can rapid page.By a Ctrl, four lamps go out entirely again, and keyboard is got back to the initialization state.

Following subordinate list is used as making of keyboard and illustrates.
