The bounding force to glass that is formed with olefines or phenylethylene below thin slice 516 on the 516B is the weak stickability bonding agent 517B of 0.01～0.5N/cm.On bonding coat 517B, be bonded with the release sheet 508 that constitutes by flexible membranes such as paper or films.That is, set a little less than the bounding force specific adhesion layer 517A of bonding coat 517B.
Fig. 9 is the sectional view of the input media 3001 of embodiment 2.The release sheet 508 of contact type panel 2001 is peeled off, then, bonding coat 517B is pasted on the display surface 510A of display elements 510 such as liquid crystal display cells.Electrode 532A, 532B are connected with the electronic circuit of equipment with electrode 533A, 533B, and are installed on the electronic equipment.
The operator on one side looks demonstration on the display surface 510A that recognizes display element 510 by contact type panel 2001, on one side with finger or when pushing the top 501A of substrate 501, and substrate 501 deflections, the resistive layer 503 at the position that is urged contacts with resistive layer 504.Electronic circuit applies voltage between electrode 532A, 532B, and the voltage of detecting electrode 533A or electrode 533B.Electronic circuit is calculated the position of the direction 2001A at the position that is pressed from detected voltage.Then, electronic circuit applies voltage between electrode 533A, 533B, and the voltage of detecting electrode 532A or electrode 532B.Electronic circuit is calculated the position of the direction 2001B at the position that is pressed from detected voltage.Thus, can calculate the direction 2001A at the position that is pressed, the position of 2001B.Electronic circuit is according to each function of the position switching device of calculating.
When pasting contact type panel 2001 on the display element 510, the situation that produces the stickup deviation because of dislocation etc. is arranged.Because contact type panel 2001 sticks on the display element 510 by the weak stickability bonding coat 517B of the following 516B of thin slice 516, therefore, contact type panel 2001 is temporarily peeled off from display element 510 easily, and is attached to again on the display element 510.
Promptly, with contact type panel 2001 when display element 510 is peeled off, thin slice 516 and substrate 502 are bondd by strong stickability bonding coat 517A, and display element 510 and thin slice 516 are by the weak stickability bonding coat 517B bonding of bounding force a little less than than strong stickability bonding coat 517A.Therefore, thin slice 516 continues to be bonded on the substrate 502, peels off from display element 510.Therefore, after contact type panel 2001 is peeled off, do not need thin slice 516 is peeled off once more from display element 510.
Weak stickability bonding coat 517B with to a little less than the bounding force of glass to the degree of 0.01～0.5N/cm be coated in thin slice 516 below on the 516B, therefore, weak stickability bonding coat 517B can transfer printing and attached on the display element 510.Therefore, after peeling off, do not need to remove bonding coat 517B attached to above the display element 510.
Weak stickability bonding coat 517B can be formed by monomer materials such as silicon rubber or urethane rubbers.In embodiment 2, because weak stickability bonding coat 517B forms by thermoplastic elastomer (s)s such as olefines or phenylethylene, ester class, polyvinyl chlorides, therefore, the bounding force of stickability bonding coat 517B a little less than can easily regulating by the mixing ratio of material.
Weak stickability bonding coat 517B contains soft segment and the bounding force rigid segment bigger than soft segment.Under the situation that weak stickability bonding coat 517B is made of the olefin hydrocarbons thermoplasticity resilient material, contain as ethene one propylene of soft segment with as the tygon polypropylene of rigid segment.Under the situation that weak stickability bonding coat 517B is made of the styrene analog thermoplastic resilient material, contain as the polybutadiene of soft segment with as the polystyrene of rigid segment.Under the situation that weak stickability bonding coat 517B is made of the urethanes thermoplastic elastomer (s), contain as the polyester polyethers of rigid segment with as the polyurethane of soft segment.Under the situation that weak stickability bonding coat 517B is made of ester analog thermoplastic resilient material, contain as the polyether polyester of rigid segment with as the polyester of soft segment.Under the situation that weak stickability bonding coat 517B is made of the polyvinyl chloride thermoplastic elastomer (s), contain as the amorphism Polyvinylchloride of rigid segment with as the crystallinity Polyvinylchloride of soft segment.
Weak stickability bonding coat 517B contains the mutually different element of bounding force of thermoplastic elastomer (s), thus, by the mixing ratio of these elements, can easily regulate the bounding force of weak stickability bonding coat 517B.Therefore, can regulate the bounding force of weak stickability bonding coat 517B according to the bounding force of strong stickability bonding coat 517A, and can contact type panel 2001 be peeled off from display element 510 with desirable peeling force.
With contact type panel 2001 when display element 510 is peeled off, owing to weak stickability bonding coat 517B must be peeled off from display element 510, therefore, the material that preferably will be 1～10N/cm to the bounding force of glass makes the bounding force of weak stickability bonding coat 517B stronger as strong stickability bonding coat 517A.

Figure 10 A is the sectional view of the contact type panel 2002 of embodiment 3.Figure 10 B is the sectional view of the input media 3002 of embodiment 3.Among Figure 10 A, Figure 10 B, the part mark identical symbol identical with the contact type panel 2001 shown in Fig. 8 A and input media shown in Figure 9 3001 omits its explanation.
In contact type panel 2002, substrate 501 is made of polycarbonate or polyethersulfone, and substrate 502 is made of polycarbonate, polyethersulfone, glass etc.Contact type panel 2002 has the film 516 that thin slice 1516 replaces contact type panel 2001.Thin slice 1516 is by the polarizer that films such as polycarbonate or cycloolefine polymer is extended and have 1/4 wavelength of many warpages property.
On substrate 501, be provided with the polarizer 520 that constitutes by the material identical on the 501A with thin slice 1561.On polarizer 520, be provided with polarization plate 521 on the 520A.Polarization plate 521 is by absorption iodine or dyestuff and make that it extends, directed sheet of polyvinyl alcohol and this above thin slice and below stacked triacetyl cellulose constitute.Constitute circularly polarized light type contact type panel 2001 by polarizer 520 and thin slice 1516.
In contact type panel 2002, identical with contact type panel 2001, by contact type panel 2002 521A above polarization plate 521 look recognize be pasted on film 1516 below display element 510 on the 1516B.When exterior light such as sunshine above coming from polarization plate 521 or light see through polarization plate 521, externally the directions X of light and with the polarized light of the Y direction of its quadrature in, for example polarization plate 521 absorbs the polarized light of Y directions.Become the rectilinearly polarized light of directions X by the exterior light of polarization plate 521, incide on the polarizer 520 from polarization plate 521.
Secondly, this light makes polarization plane only rotate 45 degree by the polarizer 520 of 1/4 wavelength.Reflect upward towards polarization plate 521 by resistive layer 504 by substrate 501 or resistive layer 503.
The polarizer 520 that the light that has reflected sees through 1/4 wavelength once more makes its polarization plane only rotate 45 degree.Thus, only revolve and turn 90 degrees, penetrate from polarizer 520 once more, incide on the polarization plate 521 even incide light on the polarizer 520 1/2 wavelength polarization plane that staggers.Because polarization plate 521 only makes the light wave of directions X see through, therefore, will interdict from the light that polarizer 520 penetrates, can not penetrate from top 521A.
That is, the exterior light of the top incident of 521A is reflected upward by resistive layer 504 above polarization plate 521.But this reflected light is polarized tabula rasa 521 blockings, can not penetrate from top 521A.Therefore, obtain can not being reflected, identity is good and see the contact type panel 2002 of the demonstration of display element easily.
