Description

A kind of changing refers to many signals input operation key

(1), affiliated technical field

The utility model relates to a kind of input equipment that is used on the electric equipment, the keyboard on particularly a kind of electrical equipment input equipment or the operating key of operating surface platform.

(2), technical background

The existing operating key that is used on the electrical equipment input equipment generally is made up of shell frame, keycap, elasticity reset device and control circuit.This generic operation key exists the single shortcoming of signal input, the only corresponding signal of operating key, though the corresponding plural signal of some operation bond energy, but must realize by the switching of alternate function key, perhaps mode such as the number of times by keystroke and speed realizes, this brings many inconvenience to the operator, this generic operation key makes the bond number on operating surface platform or the keyboard too much, as computer keyboard, volume is big, and operating surface is wide, and people must adopt bimanualness just can reach the purpose of quick typing, and the error rate height, the operation of both hands fingering is difficult to be grasped.

(3), summary of the invention

The purpose of this utility model just provides a kind of simple in structure, easy to operate changing and refers to many signals input operation key, and it can refer to operate in by changing of one hand imports plural signal fast on the operating key.

The purpose of this utility model is to realize by such technical scheme, it includes shell frame, keycap, elasticity reset device and control circuit, it is characterized in that: also include one or more transducing signal films that are used with finger, keycap or operating key position are provided with one or more sensors different and that be connected with control circuit.

Sensor is an existing mature technology, and class is kind more than 60, and kind is thousands of, as magnetoelectric transducer, photoelectric sensor, metal sensor, chemical fibre sensor, capacitive transducer, pressure transducer etc.The principle of work of sensor is: when sensor contact or near the time, sensor plays induction.Therefore, sensor is arranged on operating key position or the keycap, by the finger of having the transducing signal film and the finger difference button that does not have the transducing signal film, or by each finger difference button with different transducing signal film, sensor will play induction or not play induction, to control circuit transmission signal not of the same race, to be implemented in the purpose of a plurality of signals of input on the operating key.

Principle of work of the present utility model is such:

1. when on keycap or operating key position, a sensor only being set, can refer to that mode of operation is implemented in two signals of input on the key with changing of finger.The operator will have the transducing signal film on the finger, when using the finger push key of no transducing signal film, sensor will not play induction, after control circuit is handled, send the order that receives a kind of signal; When the finger of using the transducing signal film instead is pressed same operating key, sensor will play induction, after control circuit is handled, send the order that receives another kind of signal.For example, an exploitation keys is shown " AB ", represents to have on this key A and two signals of B to be imported by this key, when needs inputs A, only needs to press this key with finger that the transducing signal film is arranged or the finger that do not have a transducing signal film and gets final product; When needs inputs B, only need with no transducing signal film or have the finger of transducing signal film to press this key to get final product.

2. when on keycap or operating key position, being provided with two different sensors altogether, adopt capacitive transducer as a sensor, another sensor adopts magnetoelectric transducer, can refer to that mode of operation is implemented in the signal of input below three or three on the key with changing of finger.The operator is respectively with on two fingers and the corresponding transducing signal film of sensor, and when using the finger push key of no transducing signal film, sensor will not play induction, after control circuit is handled, sends the order that receives first kind of signal; When using instead when pressing same operating key with the finger of the corresponding transducing signal film of capacitive transducer, capacitive transducer will play induction, after control circuit is handled, send the order that receives second kind of signal; When using instead when pressing same operating key with the finger of the corresponding transducing signal film of magnetoelectric transducer, magnetoelectric transducer will play induction, after control circuit is handled, send the order that receives the third signal.For example, an exploitation keys is shown " ABC ", represents to have on this key A, B and three signals of C to be imported by this key, when needs input A, only needs to press this key with the finger that has or not the transducing signal film and gets final product; When needs inputs B, only need to press this key with the finger of the corresponding transducing signal film of capacitive transducer and get final product with having; When needs inputs C, only need to press this key with the finger of the corresponding transducing signal film of magnetoelectric transducer and get final product with having.

3., when the different sensor that is provided with altogether more than three, can refer to that mode of operation be implemented in N or N following signal of input on the key with changing of finger on keycap or operating key position, wherein the size of N equals the sensor number and adds one.

Owing to adopted technique scheme, the utlity model has following advantage:

1. simple in structure, easily manufactured, working stability, good reliability;

2. refer to operate in by changing of one hand and import a plurality of signals on the button fast, fingering easy simple to operate, easy to operate;

3. the corresponding plural signal input of button can make operation face or the required bond number of keyboard significantly reduce, and volume obviously dwindles;

4. according to user's needs, but the various layouts of flexible design are more reasonably operated face or keyboard;

5. not only be useful for computer keyboard, and be applicable to such as on the input equipments such as mobile phone, counter, instrument and meter, intelligent electric appliance.
