Please referring to Fig. 3, be the synoptic diagram of the folded state of this keyboard.Keyboard described in the figure is folded into three foldings.This is because the keyboard face of this keyboard is a plane, and adopts frivolous flexible foldable material to make.This flexible material can fold curling, so that carry.Therefore, this kind keyboard has the unrivaled convenience of common keyboard.
Fig. 4 illustrates the keyboard face of this keyboard and forms structure.
This illustrates, and the keyboard face of this keyboard comprises three layers, is respectively from bottom to up: first circuit layer 1, separation layer 2, second circuit layer 3.Above-mentioned three layers closely fit together.
Please referring to Fig. 5, this illustrates the arrangement of conductors synoptic diagram of first circuit layer 1.The processing unit 4 that is positioned at keyboard face one end also is shown among the figure.This illustrates the lead that described first circuit layer, 1 surface arrangement has densely covered horizontal parallel distribution, and for reaching sensing effect preferably, rule separated by a distance is furnished with the relatively large node of some areas 5 on lead.The lead of this horizontal parallel distribution can be used to detect the lengthwise position that is pressed a little.
Please referring to Fig. 6, this illustrates described second circuit laminar surface and is furnished with the lead that densely covered parallel longitudinal distributes, and for reaching sensing effect preferably, rule is furnished with the bigger node of some areas 6 on lead.Described node 6 is quantitatively identical with the node 5 of first circuit layer, overlapping one by one correspondence on the locus.Above-mentioned lead all is connected in the described processing unit 4.The lead that should vertically distribute can detect the lateral attitude that is pressed a little.
The layout of lead also can be that first circuit layer 1 is arranged the lead that parallel longitudinal distributes in above-mentioned first circuit layer 1 and the second circuit layer 3, simultaneously, second circuit layer 3 is arranged the lead of horizontal parallel distribution, and this moment, first circuit layer 1 was also opposite with the implication that second circuit layer 3 detects the positional information that obtains.
Please continue referring to Fig. 4.Shown in the figure, between described first circuit layer 1 and second circuit layer 3, has separation layer 2.This separation layer 2 is a kind of insulation film, and has through hole in the position corresponding with node 5, node 6 on described first circuit layer 1 and the second circuit layer 2.
Described first circuit layer 1, separation layer 2 and second circuit layer 3 all use frivolous flexible material to make, and fit tightly between three layers.
When described keyboard face is in free state, since the effect of separation layer 2, the lead mutually insulated on first circuit layer 1 and the second circuit layer 2.
When described keyboard face was pressed, owing to have through hole on the separation layer 2, under the effect of pressure, the node 5 of first circuit layer 1 of this position contacted and conducting by the through hole of separation layer 2 in this position with the node 6 of corresponding second circuit layer 3.Detect the change of above-mentioned electricity condition, can obtain that the keyboard face is pressed and the information of pressing position.
Below in conjunction with the introduction of processing unit 4, illustrate that above-mentioned keyboard face is pressed and how detected the information of pressing position is.
Please referring to Fig. 7, this illustrates the composition frame chart of described processing unit.
Described processing unit 4 has scanning element 41, detecting unit 42, signal synthesis unit 43, decoding unit 44.
The scanning element 41 generation+12V voltages of described processing unit 4 are as sweep signal, and the lead that circulates successively to the horizontal parallel distribution of described first circuit layer 1 provides this+12V voltage.Scanning element 41 offers scanning mode information described signal synthesis unit 43 simultaneously, and described scanning mode information comprises the wire size information of leading of the lead that is scanning.
Described detecting unit 42 is when described scanning element 41 scans, whether the lead that detects the parallel longitudinal distribution of second circuit layer 3 has+output of 12V detection signal voltage, if detecting certain root lead has+output of 12V voltage, can judge that then the keyboard face is pressed.This detecting unit 42 obtains the wire size of leading of described output+12V voltage and also exports.
