The computer keyboard is characterized in that a calculator LCD display screen is arranged above the auxiliary keyboard; a keyboard status indicator lamp is arranged above the calculator LCD display screen. The utility model has the advantages of compact structure, less changes, limited cost increase, convenience and practicability.
Description
The utility model relates to the instruction code keyboard, relates in particular to a kind of computer keyboard.
Along with the popularizing and promoting of computing machine, as the keyboard of computer entry device by a large amount of and frequent uses.Existing keyboard has formed a kind of standard of extensive approval at Xiao Yi of Datong District, aspect such as pattern specifications.The computer operator, though what industry, what work, in real work, often need carry out conventional numerical evaluation,, or call counter program special in the computer if go for a counter in addition, will interrupt work, upset is pondered over, and pretty troublesome.
The purpose of this utility model provides a kind of compact conformation, convenient and practical computer keyboard.
The utility model is taked following measures in order to achieve the above object, it comprises key panel, the key panel left side is provided with Master Keyboard, the panel right side is provided with companion keyboard, top between Master Keyboard and the companion keyboard is provided with the operation collateral key, the below is provided with cursor movement key, and feature is to be provided with the counter LCD display above companion keyboard.
The utility model is compared with existing keyboard:
(1) something in common
A. the two has identical size, the volume external form, and the card layout is basic identical.Especially the arrangement of button and position do not change, so do not influence user's fingering and operating habit.
B. the two compares on function, and novel keyboard has comprised the function of existing keyboard fully, does not have what variation concerning user and software business man.That is to say that this keyboard has good compatibility, versatility and inheritance.
(2) superior part
A. the person accomplishes that really " at hand " just has a counter to use the novel keyboard, can do some conventional digital operations with it, and is very convenient, practical.The needs of user's reality have been satisfied.
B. novel keyboard has been owing to added very practical calculator function on existing keyboard, makes product acquisition advantage in market competition.
C. additional arithmetical unit is concerning keyboard factory, and related technology and device all are disclosed and general, only need do a small amount of change, realize that easily the cost of increase is limited.
Elaborate below in conjunction with accompanying drawing:
Accompanying drawing is a kind of calculator keyboard structural representation.
A kind of computer keyboard, it comprises key panel 2, the key panel left side is provided with Master Keyboard 1, the panel right side is provided with companion keyboard 5, top between Master Keyboard and the companion keyboard is provided with operation collateral key 4, the below is provided with cursor movement key 3, the said counter LCD display 6 that is provided with of feature above companion keyboard.Counter LCD display 6 tops are provided with keyboard state pilot lamp 7.0,1,2,3,4,5,6,7,8,9 10 numeric keys and "+", " ", " * ", "/" four calculation keys are arranged on companion keyboard, also have carriage return ". ", " Enter " and " Num Lock " key, these keys just can be formed a counter input keyboard.
The utility model functional description: press " Enten " key on the companion keyboard when pressing " Num Lock " key again, the logical circuit of keyboard blocks companion keyboard, makes the right companion keyboard enter the arithmetical unit state, and at this moment the function of other key is constant fully on the keyboard; The key of companion keyboard does not transmit to computing machine if be pressed, but becomes the input of counter.The companion keyboard and the counter liquid crystal display on keyboard the right have just been formed a compact conformation, the rational counter of function like this.When pressing " Num Lock " and " Enten " key once more simultaneously, withdraw from the counter state, the duty of keyboard at this moment returns to general state fully, and at this moment liquid crystal display can show some informations.As seen only need switch, just can activate the not high companion keyboard of frequency of utilization is the counter that has only usefulness, thereby can realize same keyboard fully in input equipment, can work as counter again and use, not conflict mutually on both functions as computing machine.The counter power consumption seldom, the power supply of its power supply and keyboard operating circuit and together, so this counter need not powered battery, as long as a start, the calculator function of keyboard just can be activated at any time, no matter what software you are moving.(note: " Num Lock " key itself is different to the switching of the calculator function that the handoff functionality of companion keyboard and it and " Enten " key combination are carried out, but the two does not conflict, and does not influence under the normal condition " Num Lock " key to the blockade handoff functionality of companion keyboard.) during computing, can be the Enten key as evaluation and remove function key, can import behind the formula again by Enten key evaluation, its result can be used as first operand of next formula, otherwise removes this number by the Enten key.If add being used of other key on the Master Keyboard, also can extend the computing function of this counter greatly.For realizing this new keyboard, place to the existing required change of keyboard on production technology is few, the circuit that increases for arithmetical unit also seldom just had many spaces originally in the keyboard shell, can hold the circuit block (original scanner uni control section is constant substantially) of these increases fully.The technical scheme of being made of a counter companion keyboard sweep circuit, integrated compute chip, LCD Controller chip, LCD display and logic control circuit is disclosed and general, can according to circumstances apply in a flexible way.On sale on the device markets such as special-purpose integrated compute chip, LCD Controller chip, the companion keyboard sweep circuit also utilizes original sweep circuit as far as possible.
