And, at the 1st row column liner 36 of left lateral (among the figure), arrange along the limit that keeps left of propagation regions 41, dispose column liner 36 at the central portion of the above-below direction on this limit that keeps left.With the column liner 36 that is disposed at this central portion is the center, up and down uniformly-spaced to dispose a plurality of column liners 36.And, also be same arrangement at right lateral.
And,, respectively be offset the configuration of half spacing ground at left and right directions since each row of the 2nd row; Since the 2nd each row of row, respectively be offset the configuration of half spacing ground simultaneously at above-below direction.So, in propagation regions 41, become to be symmetrical in respectively and dispose column liner 36 up and down.
In addition, this column liner 36 makes and goes up ground with the straight line (representing with dotted line in scheming) that uniformly-spaced is arranged in along the direction of propagation of surface acoustic wave, sets spacing.So, column liner 36 is arranged in the propagation regions 41 along the direction of propagation of surface acoustic wave.In the drawings, though in the part that column liner 36 is not set also with shown in the dotted line, also can be on this dotted line, perhaps, suitable configuration column liner 36 on the intersection point of these dotted lines.And, also can be for from remove the configuration of a part of column liner 36 at the state shown in Fig. 2.
Based on Fig. 3 and Fig. 4, the situation the when user is touched touch panel 3 describes.Fig. 3 is the mode chart of expression user with the situation of finger touch touch panel 3.Fig. 4 is the curve map of expression by an example of the envelope waveform of receiver side transducer 35 detected surface acoustic waves.The transverse axis express time of curve map, the intensity of longitudinal axis presentation surface sound wave.
As be shown among Fig. 3 ground, if the user is with finger touch input area 40, then the 1st touch panel substrate 31 of this position that is touched is contacted with the 2nd touch panel substrate 32 to 32 bendings of the 2nd touch panel substrate.The surface acoustic wave W that propagates on the surface of the 2nd touch panel substrate 32 absorbing by the 1st touch panel substrate 31 when being contacted with the part of the 1st touch panel substrate 31, propagates under the state about amplitude fading is to half.
On the other hand,, as be shown among Fig. 4 ground because the user touches the 1st touch panel substrate 31, at the envelope waveform of surface acoustic wave, course of emergency time t1 and size is the disappearance (part that decays P) of A1.In above-mentioned control circuit, mensuration detects surface acoustic wave W from receiver side transducer 35 and plays the time T g that decay part P takes place, the coordinate at the position that touched is determined in position on the 1st touch panel substrate 31 that has decayed based on this time T g gauging surface sound wave W.
And, in the envelope waveform of Fig. 4, periodically form through certain time t2 and amplitude becomes zero decay part Q.This decay part Q is when surface acoustic wave W propagates, owing to a plurality of column liners 36 formed decay on same the dotted line that is disposed at Fig. 2.Because column liner 36 is uniformly-spaced to be configured to along the linearity of the direction of propagation of surface acoustic wave W, so should occur with certain cycle by decay part Q.
And because of the decay part Q that column liner 36 causes, the decay that is compared to the short amplitude of decay part P time that the touch because of the user causes is big (A2) also, occurs with certain cycle.Thereby for example the characteristic by the part Q that will decay is stored in the control circuit in advance, can easily discern the decay part P that the touch because of the user causes.
So, because according to present embodiment, become by the fitted formation of the 1st touch panel substrate 31 and the 2nd touch panel substrate 32 of encapsulant 33, even so under the 2nd touch panel substrate 32 damaged situations, also can cover, can prevent separation of fragments by the 1st touch panel substrate 31.
And, even at object (finger tip with hard, nib etc.) under the situation of having carried out writing or touching, also be always by resin material and form the 1st membranaceous touch panel substrate 31 because of the object that is contacted with the 2nd touch panel substrate 32, so surface acoustic wave W that propagates on the surface of the 2nd touch panel substrate 32, fully being absorbed by the 1st touch panel substrate 31 when being contacted with the part of the 1st touch panel substrate 31, can guarantee high position detection capability.
And then, because column liner 36 arranges along the direction of propagation of surface acoustic wave W, so block surface acoustic wave W only in the scope of part.Thus, because the decay of the surface acoustic wave W that causes because of column liner 36 can be suppressed to Min., the insensitive zone in the 1st touch panel substrate 31 can be suppressed to Min., so can guarantee high position detection capability.
And because the scope (t2) of the decay of the surface acoustic wave W that is caused by column liner 36, the scope (t1) of the decay of the surface acoustic wave W that causes than the touch because of the user is short, so can easily distinguish the two.Thus, can prevent that decay that the touch because of the user is caused and the decay that causes because of liner from missing identification, can guarantee higher position detection capability.
