  The reinforcing member 30 is a frame-like member fixed to the lower surface of the cover member 20 via an adhesive 24 as shown in FIGS. Since the reinforcing member 30 is affixed to the shielding portion 23 of the cover member 20, the reinforcing member 30 cannot be visually recognized by the operator. In the present embodiment, an adhesive may be used in place of the adhesives 24, 25, 33, 83.

  The reinforcing member 30 has a main body portion 31 and a protruding portion 32. The main body 31 has a rectangular frame shape, and extends in a direction substantially parallel to the main surface of the cover member 20. On the other hand, the protruding portion 32 has a rectangular tube shape communicating with the opening 311 of the main body portion 31 and protrudes downward from the inner edge of the main body portion 31.

The main body 31 and the protrusion 32 are integrally formed.

  As shown in FIG. 5, the touch panel 40 is a capacitive touch panel that includes two electrode sheets 41 and 42 that are superposed on each other. The structure of the touch panel is not particularly limited to this, and for example, a resistive film type touch panel or an electromagnetic induction type touch panel may be employed. Moreover, the 1st electrode pattern 412 and the 2nd electrode pattern 422 which are demonstrated below may be formed in the lower surface of the cover member 20, and the cover member 20 may be utilized as a part of touch panel.

Exemplify resin materials such as vinyl copolymer resin (EVA), vinyl resin, polycarbonate (PC), polyamide (PA), polyimide (PI), polyvinyl alcohol (PVA), acrylic resin, triacetyl cellulose (TAC) Can do.

  The first electrode pattern 412 is, for example, a transparent electrode made of indium tin oxide (ITO) or a conductive polymer, and is a strip-shaped planar pattern (so-called so-called) extending along the Y direction in FIG. Solid pattern). In the example shown in FIG. 5, nine first electrode patterns 412 are arranged in parallel to each other on the first transparent substrate 411. Note that the shape, number, arrangement, and the like of the first electrode pattern 412 are not particularly limited to the above.

  When the first electrode pattern 412 is made of ITO, it is formed by sputtering, photolithography, and etching, for example. On the other hand, when the first electrode pattern 412 is made of a conductive polymer, it may be formed by sputtering or the like as in the case of ITO, or a printing method such as screen printing or gravure offset printing, It may be formed by etching after coating.

  Specific examples of the conductive polymer constituting the first electrode pattern 412 include organic compounds such as polythiophene, polypyrrole, polyaniline, polyacetylene, and polyphenylene, among which PEDOT It is preferable to use a / PSS compound.

  The first electrode pattern 412 may be formed by printing a conductive paste on the first transparent substrate 411 and curing it. In this case, in order to ensure sufficient light transparency of the touch panel 30, each first electrode pattern 412 is formed in a mesh shape instead of the planar pattern. As the conductive paste, for example, a mixture of metal particles such as silver (Ag) or copper (Cu) and a binder such as polyester or polyphenol can be used.

  The plurality of first electrode patterns 412 are connected to a touch panel drive circuit (not shown) via the first lead wiring pattern 413. The first lead wiring pattern 413 is provided on the first transparent base material 411 at a position facing the shielding portion 23 of the cover member 20, and the operator pulls the first lead wiring pattern 413 from the operator.

  The second transparent substrate 421 is made of the same material as the first transparent substrate 411 described above. The second electrode pattern 422 is also a transparent electrode made of, for example, indium tin oxide (ITO) or a conductive polymer, like the first electrode pattern 412 described above.

  The second electrode pattern 422 is constituted by a strip-like planar pattern extending along the X direction in FIG. In the example shown in FIG. 5, six second electrode patterns 422 are arranged in parallel to each other on the second transparent substrate 421. The shape, number, arrangement, etc. of the second electrode wiring pattern 422 are not particularly limited to the above.

  The plurality of second electrode patterns 422 are connected to a touch panel drive circuit (not shown) via the second lead wiring pattern 423. Note that the touch panel drive circuit periodically applies a predetermined voltage between the first electrode pattern 412 and the second electrode pattern 422, for example, for each intersection of the first and second electrode patterns 412 and 422. The position of the finger on the touch panel 40 is detected based on the change in capacitance.

  The second lead-out wiring pattern 423 is provided on the second transparent substrate 421 at a position facing the shielding portion 23 of the cover member 20, and the operator pulls out the second lead-out wiring pattern 423. It is not visible. For this reason, like the above-mentioned 1st extraction wiring pattern 413, this 2nd extraction wiring pattern 423 is also formed by printing the electrically conductive paste on the 2nd transparent base material 421, and hardening it.

  The first electrode sheet 41 and the second electrode sheet 42 are attached to each other via a transparent adhesive so that the first electrode pattern 412 and the second electrode pattern 422 are substantially orthogonal in a plan view. It has been. Further, the touch panel 40 itself is also attached to the lower surface of the cover member 20 via the transparent adhesive 25 so that the first and second electrode patterns 412 and 422 face the transparent portion 22 of the cover member 20.

The first through hole 531 is opposed to the screw hole 321 formed in the protruding portion 32 of the reinforcing member 30 described above. On the other hand, the second through hole 532 faces a screw hole 81 (described later) of the support member 80.

  As shown in FIG. 2, the display device 50 is fixed to the reinforcing member 30 by the bolts 54 screwed into the screw holes 321 through the first through holes 531, thereby reinforcing the display region 51. It faces the transparent portion 22 of the cover member 20 through the opening 311 of the member 30.

Is set to Thereby, since the clearance gap between the touchscreen 40 and the display apparatus 50 is lose | eliminated, the appearance of the screen in the electronic device 1 improves.

  In the present embodiment, since the touch panel 40 and the display device 50 can be brought into close contact with each other without using an adhesive, there is no possibility of foreign matters or bubbles entering between the touch panel 40 and the display device 50, and the yield of the product is improved. To do.

  Note that an adhesive (dashed line portion 521 in FIG. 6) may be applied only to the outer edge region 52 of the display device 50, and the outer edge region 52 and the touch panel 40 may be fixed. Thereby, since the rigidity of the movable unit 10 can be increased, the entire movable unit 10 can be thinned as a result by thinning the constituent members 20 to 50 of the movable unit 10. Note that an adhesive may be used instead of the adhesive 521.

  In the present embodiment, the display device 50 is directly fixed to the reinforcing member 30 by the bolts 54, but the method of fixing the display device 50 to the reinforcing member 30 is not particularly limited to this. For example, although not particularly illustrated, a holding plate is newly provided on the back surface 501 side of the display device 50, and the holding plate is fixed to the reinforcing member 30 with screws or the like, and the display device 50 is fixed to the holding plate and held. The display device 50 may be indirectly fixed to the reinforcing member 30 via a plate. That is, if the display device 50 is fixed relative to the reinforcing member 30, the display device 50 may be directly fixed to the reinforcing member 30, or the display device 50 may be indirectly attached to the reinforcing member 30. May be fixed.

  As shown in FIGS. 1 and 2, the pressure sensor 60 is attached to the four corners of the movable unit 10 described above. The configuration of the pressure sensitive sensor is not limited to the one described below as long as the pressure can be detected. For example, a capacitive pressure sensor, a pressure sensitive conductive rubber, a strain gauge, or a piezoelectric element may be used as the pressure sensitive sensor.

  As shown in FIG. 7, the pressure sensor 60 includes a first electrode sheet 61, a second electrode sheet 62, and a spacer 63 interposed therebetween. 7 is a cross-sectional view taken along line VII-VII in FIG. 8 described later.

  The first electrode sheet 61 has a first base 611 and an upper electrode 612. The first base 611 is a flexible insulating film, and is made of, for example, polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyimide (PI), polyetherimide (PEI), or the like. Yes.

  The upper electrode 612 includes a first upper electrode layer 613 and a second upper electrode layer 614, and is provided on the lower surface of the first base material 611. The first upper electrode layer 613 is formed by printing and curing a conductive paste having a relatively low electrical resistance on the lower surface of the first base 611. On the other hand, the second upper electrode layer 614 is formed by printing and curing a conductive paste having a relatively high electrical resistance on the lower surface of the first base 611 so as to cover the first upper electrode layer 613. Has been.

  The second electrode sheet 62 also has a second base material 621 and a lower electrode 622. The second base 621 is made of the same material as the first base 611 described above. The lower electrode 622 includes a first lower electrode layer 623 and a second lower electrode layer 624, and is provided on the upper surface of the second base material 621.

  The first lower electrode layer 623 is formed by printing and curing a conductive paste having a relatively low electrical resistance on the upper surface of the second base material 621 in the same manner as the first upper electrode layer 613 described above. Has been. On the other hand, in the same manner as the second upper electrode layer 614 described above, the second lower electrode layer 624 is formed of a second paste so as to cover the first lower electrode layer 623 with a conductive paste having a relatively high electrical resistance. It is formed by printing on the upper surface of the material 621 and curing it.

  Examples of the conductive paste having a relatively low electrical resistance include silver (Ag) paste, gold (Au) paste, and copper (Cu) paste. On the other hand, as a conductive paste having a relatively high electrical resistance, for example, a carbon (C) paste can be exemplified. Examples of methods for printing these conductive pastes include screen printing, gravure offset printing, and inkjet method.

  The first electrode sheet 61 and the second electrode sheet 62 are laminated via a spacer 63. The spacer 63 is made of an insulating material such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyimide (PI), or polyetherimide (PEI).

  The spacer 63 has an opening 631 at a position corresponding to the upper electrode 612 and the lower electrode 622. The upper electrode 612 and the lower electrode 622 are located in the opening 631 and face each other.

  For this reason, when a predetermined voltage is applied between the upper electrode 612 and the lower electrode 622 and a load is applied to the pressure sensor 60 from above, the upper electrode 612 approaches the lower electrode 622 and comes into contact therewith. The electrical resistance between the upper electrode 612 and the lower electrode 613 changes in accordance with the size of. The pressure-sensitive sensor 60 can detect the magnitude of the pressure applied to the pressure-sensitive sensor 60 based on this resistance change, and the electronic device 1 in this embodiment can detect the electric resistance of the pressure-sensitive sensor 60. The pressing operation of the movable unit 10 by the operator is detected by comparing the value with a predetermined threshold value.

  Note that the second upper electrode layer 614 and the second lower electrode layer 624 may be formed by printing and curing pressure-sensitive ink instead of the carbon paste. The electrode layers 613, 614, 623, and 624 described above may be formed by plating or patterning instead of printing.

  The support member 80 supports the movable unit 10 via the pressure sensor 60, and is made of, for example, a metal material such as aluminum, or a resin material such as polycarbonate (PC) or ABS resin. As described above, the pressure-sensitive sensors 60 are arranged at the four corners of the support member 80. However, as shown in FIG. 8, the support member 80 is further positioned outside the pressure-sensitive sensor 60. Further, a seal member 70 is provided along the outer edge of the support member 80.

  The annular seal member 70 is made of a material having a compression elastic modulus relatively lower than the compression elastic modulus of the pressure-sensitive sensor 60 and having a sealing property. As a specific example of the material constituting such a sealing member 70, for example, closed cell urethane foam can be exemplified. In the present embodiment, since the compression elastic modulus of the seal member 70 is relatively low as described above, the gap between the movable unit 10 and the support member 80 is prevented without hindering the pressing force applied to the pressure sensor 60. It is possible to prevent foreign matter from entering from the outside.

  As shown in FIG. 2, the pressure-sensitive sensor 60 and the seal member 70 are attached to the lower surface of the main body portion 31 of the reinforcing member 30 via an adhesive 33 and attached to the support member 80 via an adhesive 83. It has been. Thus, in this embodiment, since the pressure-sensitive sensor 60 and the seal member 70 are disposed in the space formed under the main body portion 31 of the reinforcing member 30, the electronic device 1 can be thinned. . Since both the pressure-sensitive sensor 60 and the seal member 70 are disposed behind the shielding portion 23 of the cover member 20, the operator cannot visually recognize the pressure-sensitive sensor 60 and the seal member 70. In addition, as shown in FIG. 9, the pressure sensor 60 may have an annular shape, and the pressure sensor 60 may be provided inside the seal member 70.

  As shown in FIGS. 2 and 8, two screw holes 81 are formed on the upper surface of the support member 80 so as to face the second through hole 532 of the flange 53 of the display device 50. Bolts 82 are fixed to the screw holes 81 through the second through holes 532 of the display device 50.

  The bolt 82 has a head having an outer diameter larger than the inner diameter of the second through hole 532 of the display device 50 and a shaft portion having an outer diameter smaller than the inner diameter of the second through hole 532. Yes. The movable unit 10 is restricted from being separated from the support member 80 by a predetermined distance or more while allowing a slight vertical movement by the bolt 82. Thereby, for example, when the electronic apparatus 1 is inverted, the movable unit 10 is prevented from being separated from the support member 80. The bolt 82 in the present embodiment corresponds to an example of a limiting unit in the present invention.

  As described above, in the present embodiment, the cover member 20 and the display device 50 are connected via the reinforcing member 30, and the touch panel 40 is sandwiched between the cover member 20 and the display device 50. Therefore, the rigidity of the movable unit 10 is increased. improves.

  For this reason, since the amount of bending of the movable unit 10 is reduced and the dispersion of the pressing force due to the bending can be prevented, the pressure sensor 60 can accurately detect the pressure even when the display area of the electronic device 1 is enlarged. And the detection accuracy can be improved. Moreover, since the cover member 20 can be made thin, the electronic device 1 can be made thinner and lighter.
