Abstract
The utility model relates to a pedal keyboard aid for a computer, belonging to a computer input device, characterized in that during the computer input and the operation of double keys or multiple keys, a Ctrl key and an Alt key are additionally provided with a group of foot pedal control keys corresponding to the computer keyboard for use in parallel connection. Without changing the structure of the input keyboard, the operation with both hands is changed into the operation with auxiliary legs for quickening the operating speed. Operators (an operator with single hand operation, a disabled operator) who are inconvenient to operate with both hands can be convenient to operate the computer by using the utility model.
Description
The utility model is the foot-operated auxiliary keyboard of computer, and the auxiliary keyboard as keyboard for computer belongs to computer input unit.
In the general computation, the main keyboard that uses of information input.Always there are some multikeys operations in general keyboard when the operational computations machine, as the capital and small letter conversion of letter (under the small letter state, capitalization Shift+ letter key; Under the capitalization state, lowercase Shift+ letter key); Some Chinese softwares (as more popular WPS) are english lowercase input Alt+ letter key under the Chinese character state, capitalization Shift+ letter key; Deletion in some softwares for editing is used the Alt+F1-12 function key with Ctrl+Backspace or Ctrl+Y, mode conversion, and these all require two key operations.Also have certain operations even need three key operations, enter Setup state three keys of Ctrl+Alt+Esc when starting as computing machine, Wps Chinese character software for editing need use three keys of Ctrl+Alt+ directionkeys during setting-out.These multikeys that need both hands to operate simultaneously operate in and have accounted for sizable ratio in the computer operation, have had a strong impact on operating speed, and to the operator of some bimanualness inconvenience (as an empty deviser on the other hand only, cripple etc.), operation is inconvenience more.
The purpose of this utility model is to design a kind of foot-operated auxiliary keyboard overcoming above-mentioned inconvenience, and can improve the speed of computation.
Computer of the present utility model is with riding auxiliary keyboard, foot-operated trigger board, spring and two electrodes of comprising each key on the auxiliary keyboard, two electrodes of each key that is characterised in that foot-operated auxiliary keyboard of the present utility model are in parallel with corresponding two electrodes of keyboard for computer.
The major key that is generally used for the multikey operation is Shift, Ctrl and Alt key.Most preferred embodiment of the present utility model is that foot-operated auxiliary keyboard has three keys, i.e. Shift, Ctrl and Alt key.Two electrodes of each key are in parallel with the common keyboard corresponding electrode.
Fig. 1 and Fig. 2 represent the external form and the inner structure of this enforcement respectively.1 is shift key among the figure, and 2 is Ctrl, and 3 is Alt key, and 4 is shell, and 5 is spring, and 6,7 for triggering the upper/lower electrode of key, and 8,9 is the lead-in wire of electrode, and lead-in wire links to each other with corresponding electrode in the common keyboard.
When riding trigger board, spring is compressed, and upper/lower electrode is connected, import corresponding information, so just reached the purpose of the auxiliary input of foot control, used with computor-keyboard, can be under the prerequisite that does not change the common keyboard function, make most of bimanualness become the operation that one hand adds pin, not only make things convenient for the operator of bimanualness inconvenience greatly, and can be more convenient to operate, operating speed improved, often using in the software of multikey operation, effect is more obvious.
Claims (2)
1, a kind of computer comprises the structure and the enforcement of auxiliary keyboard with foot-operated auxiliary keyboard.Of the present utility modelly be characterised in that foot-operated input signal, and the electrode of collateral key is in parallel with the electrode of the correspondent button of common keyboard, does not change the function of original keyboard.
2, by the foot-operated auxiliary keyboard of the described computer of claim 1, its characteristics are that described auxiliary keyboard has three keys, is respectively shift key, Ctrl and Alt key.
