As shown in Figure 1, the size of the directions X of described detection lug 3 and Y direction, longer than the size of the directions X of described detection lug 4 and Y direction, described detection lug 3 protrudes from each 4 limit of described detection lug 4.Described detection lug 3 from described detection lug 4 along X1, each several part that the X2 direction is outstanding, is fixed with the support 6a, the 6b that are arranged on two ends on the base 5 by cementing agent etc.And in the present embodiment, base 5 is formed by lucites such as PET or poly-propionic acid classes.
On described detection lug 4, be provided with drive division 7 with driving mechanism function.Described drive division 7 is set on the position for described detection lug 4 deflection X1 directions.And described drive division 7 applies assigned voltage, makes piezoelectric element be created in the parts of the distortion on the Z1-Z2 direction for example piezoelectric element.And, as described driving mechanism, also can coil be set, in base 5 sides magnet etc. be set and constitute magnetic circuit in detection lug 4 sides, form the magnetic circuit that detection lug 4 is driven to the Z1-Z2 direction.
The pattern diagram of described coordinate testing agency 2 is shown among Fig. 3.Like this, detection lug 3,4 can be handled as 1 resistive element jointly.Therefore, when applying the voltage of regulation at two ends to detection lug 3, when as shown in Figure 3 P point is carried out pressing operation, will for the P point to the parallel shift position of Y direction, obtain identical resistance value.And, when applying the voltage of regulation, will obtain identical resistance value to the parallel mobile position of directions X with respect to the P point at two ends to detection lug 4.
As shown in Figure 3, be made as 0V, will only be made as the 0V that is made as of 5V, Y2 side voltage then with the anode-cathode voltage that only on detection lug 3, the voltage of the end of X1 side is made as 5 volts (V), X2 side, come control detection sheet 3 and 4 alternate energisations by not shown control part like this at the voltage of the Y1 of detection lug 4 side.
When the P point was carried out pressing operation, the conductive layer 3a of detection lug 3 just contacted at the P point with the conductive layer 4a of detection lug 4, at this moment, if, then can measure voltage Vx by detection lug 4 to detection lug 3 energisings.Then, when cutting off, can measure voltage Vy by detection lug 3 to detection lug 3 energisings and to detection lug 4 energisings.At control part, the coordinate data based on described magnitude of voltage Vx, Vy is stored in storage part in advance, measures described magnitude of voltage Vx, Vy and just can obtain described operating position.
And described coordinate testing agency 2 is not limited in the resistance-type tablet, also can use the electrostatic capacity type tablet.
As depicted in figs. 1 and 2, described base 5 is provided with support portion 8,9.Described support portion 8,9 is formed the elongated shape to directions X respectively, and is fixed on Y1 side on the base 5 and each end of Y2 side.But, as also foregoing support portion being formed on the one side of base 5.With described support portion 8,9, its fixed part 8a that is made by synthetic resin is fixed on the base 5, on the surface of the Z1 of described fixed part 8a side, and the overlapping elastomeric element 8b such as rubber that are provided with.When on the part of detection lug 4 contacts, elastomeric element 8b being set like this, when detection lug 4 contacts, just can alleviate contact sound.And support portion 9 is made of fixed part and elastomeric element too.
As shown in Figure 2, the height dimension H of described support portion 8,9, the surface that is formed with the Z2 side of described detection lug 4 has the size of minim gap 11.That is, when driving detection lug 3,4 when driving described drive division 7, detection lug 3,4 produces excessive deformations, is the conductive layer 3a that the avoids detection lug 3 careless size of setting described gap 11 that contacts with the conductive layer 4a of detection lug 4.
In the present embodiment, as shown in Figure 2, from the lap of the detection lug 3 of X1 side and detection lug 4, be set to S1 to the size of the gap 12a of the fixed part of the detection lug 3 of support 6a.In addition, in opposite X2 side, the gap 12b of the fixed part of detection lug 3 that will be from described lap to support 6b is sized to the S2 shorter than described size S1.
In the coordinate entering device 1 that forms as described above,, then will give detection lug 4, and detection lug 4 and detection lug 3 are vibrated to the Z1-Z2 direction together based on the vibration transfer that driving force produces as if driving that drive division 7 is switched on.Like this, just can make the function of detection lug 3,4 performances, from described detection lug 3,4, send acoustic pressure as oscillating plate.In addition, when described drive division 7 being arranged on the end of X1 side of deflection detection lug 4, at the gap 12a that makes detection lug 3 during, just produce outstanding distortion to the Z2 direction at the gap of X2 side 12b to the side-prominent distortion of Z1.
Described gap size S1 of Fig. 4 (A) expression and S2 are set to the vibrational state when same, if but be arranged to gap 12a, 12b both sides unidimensional like this, then when drive division 7 is driven, in the X1 of detection lug 3 side, represent that with symbol a1 the acoustic pressure of phase place can send to the Z1 direction, and the acoustic pressure of representing with symbol a2 in the X2 side, be antiphase with the former is sent to the Z1 direction.
Like this, for send in the X1 of detection lug 3 side and X2 side amplitude identical, be the acoustic pressure of antiphase mutually, carry out to the direction of cancelling out each other to mutual acoustic pressure, make sound can not export or weaken voice output.
At this, shown in Fig. 4 (B), the gap 12a size S1 of X1 side is arranged to longer than the gap 12b size S2 of X2 side, the acoustic pressure of the acoustic pressure of sending in the X1 side for representing with symbol b1, the acoustic pressure of sending in the X2 side is shown in symbol S2, compare with described acoustic pressure b1, for antiphase and amplitude little.Therefore, do not repeal by implication, can send the big acoustic pressure of output from detection lug 3,4 in X1 side and X2 side, acoustic pressure.
And in the above-described embodiments, described gap 12a is different with the 12b size, but is not limited in this, and for example each gap that also can both sides is set to identically, and changes the rigidity of detection lug 3 both sides.Perhaps, also detection lug 3 can be supported on the support 6a (or 6b) as fulcrum rotationally with an end.
In the e-machine that is equipped with above-mentioned coordinate entering device 1, be provided with the display panel 20 that forms by liquid crystal or organic EL (electroluminescence) etc. at the back side of coordinate entering device 1.This display panel 20 can show rest image or animation picture, and can import various operations based on described image.In the present embodiment, because detection lug 3,4, conductive layer 3a, 4a and base 5 all are transparent, so, even described display panel 20 is set, also can see clearly by the shown image of display panel 20 from guidance panel 1A side at base 5 back sides.And, also display panel 20 can be arranged between detection lug 4 and the base 5.
Like this, in the e-machine that is equipped with described coordinate entering device 1 and display panel 20, can carry out various input operations according to the picture of output on display panel 20, simultaneously, from the also exportable sound of display panel 20.Therefore, when e-machine is looked squarely in the front, physical dimension can be designed to size, the miniaturization of implement device and slimming near display panel 20.In addition, because detection lug 3,4 can the double as loudspeaker, so can reduce number of components, reduce manufacturing cost.
In addition, although understand the function that in described coordinate entering device 1, has as so-called loudspeaker.But be not limited in this, also can be used as feedback function and use.So-called feedback function, be meant for example in e-machines such as PDA, when cursor moves to the position that menu on the picture shows, when crossing the boundary line that menu shows or when moving to the icon display place, can make detection lug 3,4 vibrations and make operator's hand or finger experience certain power.Thus, can not only depend on vision, and can perception go out cursor moving to described each position by the thoughts and feelings of operator's hand.
What Fig. 5 and Fig. 6 represented is the variation of described coordinate entering device 1.This coordinate entering device 30, its coordinate testing agency 2 is set on the base 5, and each edge part on 4 limits by described base 5 and elastic support member 31a, 31b, 31c and 31d support each edge part on 4 limits of described coordinate testing agency 2.Described elastic support member 31a～31d is the circular-arc parts of being made by materials such as synthetic resin, but is not limited in this.In the present embodiment, the both ends of elastic support member 31a are connected with each end of elastic support member 31b, 31d, in addition, the both ends of elastic support member 31c are connected with each end of elastic support member 31b, 31d opposite side, by the space between next airtight coordinate testing agency 2 of described elastic support member 31a～31d and the base 5.
Owing to formed such confined space, therefore, when making drive division 7 vibrations, sent acoustic pressure in the X1 of coordinate testing agency 2 side direction Z1 side, and send acoustic pressure in X2 side direction Z2 side.At this moment,, prevented to leak in the Z1 side because the acoustic pressure of sending to the Z2 side is interdicted at described elastic support member 31a～31d, so, the situation that can not occur making the output in the acoustic pressure of X1 side direction Z1 side output to reduce.
In addition, on described base 5, be provided with support portion 32a, 32b, 32c and the 32d that is formed elongated shape along its periphery with the picture frame shape.Each support portion 32a～32d in coordinate entering device 1, similarly is sized to can not cause the careless degree that contacts with the counter electrode of described coordinate testing agency 2 with front explanation.
