Description

  The present invention relates to a touch panel, and more particularly, to a touch panel that detects a touch position by a resistance method.

Conventionally, a touch panel that detects a touch position at which a surface is touched by a resistance method has been put to practical use. In a resistance-type touch panel, for example, two conductive films are arranged to face each other, and one conductive film touched by a finger is curved and contacts the other conductive film. Thus, the potential of the conductive film corresponding to the contact position is measured, and the touch position is calculated based on the potential.
However, there is a problem that the contact area becomes large and the touch position cannot be detected with high accuracy because one of the conductive films is in contact with the other conductive film on the curved surface.

  Therefore, as a technology for detecting a touch position with high accuracy, for example, Patent Document 1 proposes a touch panel assisting device that realizes input with the same operability as a small keyboard when inputting characters. In this touch panel auxiliary device, a projection is provided on a flexible auxiliary sheet, and the conductive film can be locally pressed by the projection, and a touch position can be detected with high accuracy.

The detection wiring section 8 is disposed so as to extend linearly from the detection terminal 12 along the resistor 6. The detection wiring section 8 has a lower resistance value than the resistor 6 and can be made of, for example, silver.

  The plurality of resistor electrode portions 9 are connected to the resistor 6 at an interval. Specifically, the resistor electrode portions 9 are arranged and formed so as to extend in a comb-like shape at equal intervals from the resistor 6 toward the detection wiring portion 8. Further, each of the resistor electrode portions 9 has a resistance much lower than that of the resistor 6 so as to have substantially the same potential as the connection portion with the resistor 6, that is, to prevent a potential gradient from occurring at the same resistor electrode portion 9. Has a value. For example, the resistor electrode section 9 can be made of silver or the like.

The plurality of sensing electrode units 10 are connected to the sensing wiring unit 8 at an interval. Specifically, the detection electrode portions 10 are arranged so as to extend in a comb-like manner at equal intervals between the resistor electrode portions 9 from the detection wiring portion 8 toward the resistor 6. The sensing electrode section 10 has substantially the same resistance as the resistor electrode section 9 and can be made of, for example, silver.
Here, a region where the plurality of resistor electrode portions 9 and the plurality of detection electrode portions 10 are arranged is defined as a detection region R, and a touch position P is detected by touching the detection region R.

  The touch electrode section 13 is for electrically connecting the plurality of resistor electrode sections 9 and the plurality of detection electrode sections 10, and is provided for the plurality of resistor electrode sections 9 and the plurality of detection electrode sections 10. They are arranged on the base material 5b so as to face each other with a gap. Further, the touch electrode portion 13 is formed so as to cover the plurality of resistor electrode portions 9 and the plurality of detection electrode portions 10, that is, to spread in a planar manner over the entire detection region R in the other base material 5b. The touch electrode section 13 has substantially the same resistance as the resistor electrode section 9 and can be made of, for example, silver.

The power supply terminals 11a and 11b are for connecting the resistor wiring portions 7a and 7b to the power supply portion 2.
The detection terminal 12 is for connecting the detection wiring section 8 to the measurement section 3.

The fixing plate 14 has a long plate shape and is arranged so as to be in contact with the base member 5a, and the base member 5a is fixed to the surface thereof. Further, the fixing plate 14 is made of a material having higher rigidity than the base materials 5a and 5b.
The cover plate 15 has a long plate shape, and is arranged so as to sandwich the base member 5b between the cover plate 15 and the base member 5a. Further, the cover plate 15 is made of a material having higher rigidity than the base materials 5a and 5b and capable of bending in response to the pressing of the touch. The cover plate 15 can be made of, for example, a resin material such as polyethylene terephthalate and a metal.

  The linear projecting portion 16 is disposed on the inner surface of the cover plate 15 facing the substrate 5b so as to face the substrate 5b with a gap therebetween. It is formed so as to extend linearly in a direction intersecting the plurality of sensing electrodes 9 and the plurality of sensing electrode portions 10. Here, the linear projecting portion 16 is formed so as to extend in the sensing region R in the arrangement direction D1 of the plurality of resistor electrode portions 9 and the plurality of sensing electrode portions 10. In addition, the linear protrusion 16 is formed so as to linearly extend substantially in the center in the width direction D2 orthogonal to the arrangement direction D1 in the detection region R.

  Further, a fixing portion 17a is arranged between the base material 5a and the base material 5b, and a fixing portion 17b is arranged between the cover plate 15 and the base material 5b. The fixing portion 17a is arranged so as to surround the detection region R, and fixes the base material 5a and the base material 5b to each other by bonding. Similarly, the fixing portion 17b is disposed so as to surround the detection region R, and bonds the base member 5b and the cover plate 15 to each other by bonding.

The power supply unit 2 supplies power to the resistor 6 via the power supply terminals 11a and 11b.
The measurement section 3 measures the potential of the resistor electrode section 9 corresponding to the touch position P via the detection terminal 12.
The calculation unit 4 is connected to the measurement unit 3 and calculates the touch position P based on the potential of the resistor electrode unit 9 measured by the measurement unit 3.

Next, the operation of this embodiment will be described.
First, as shown in FIG. 1, power is supplied from the power supply unit 2 to the resistor 6 via the power supply terminals 11a and 11b, and a potential distribution is formed on the resistor 6. Here, each of the plurality of resistor electrode portions 9 has a resistance value lower than that of the resistor 6 so as to have substantially the same potential as that of the connection portion with the resistor 6. Therefore, the plurality of resistor electrode portions 9 are arranged in the arrangement direction D1 with the same potential distribution as the resistor 6. That is, the plurality of resistor electrode portions 9 are formed so as to intermittently draw the potential of the resistor 6 to the detection wiring portion 8 side.

  Subsequently, as shown in FIGS. 2A and 2B, when the outer surface 15a of the cover plate 15 is touched with a finger, the cover plate 15 is bent toward the base material 5b in response to the touch. Change posture. Accordingly, the linear protrusion 16 disposed on the cover plate 15 is also curved, and a portion of the linear protrusion 16 corresponding to the touch position P is pressed against the base material 5b. The base material 5b against which the linear protrusion 16 is pressed is curved toward the base material 5a together with the touch electrode unit 13. Thereby, the resistor electrode section 9 corresponding to the touch position P and the detection electrode section 10 are electrically connected by the touch electrode section 13.

  As described above, since the linear protrusions 16 are arranged so as to linearly extend in the arrangement direction D1 while protruding from the inner surface of the cover plate 15, the pressing force due to the touch is not diffused in the arrangement direction D1 in the arrangement direction D1. The transmission can be performed, and the resistor electrode section 9 corresponding to the touch position P and the detection electrode section 10 can be reliably connected. In addition, since the linear protrusions 16 are arranged on the cover plate 15, the deformation of the resistor electrode portion 9 and the detection electrode portion 10 is smaller than that in the case where the linear protrusions are arranged on the touch electrode portion 13, for example. Can be suppressed, and the connectivity between the resistor electrode section 9 and the detection electrode section 10 can be maintained.

Further, since the linear protrusion 16 is formed so as to extend in the detection region R in the arrangement direction D1, the resistor electrode portion 9 and the detection electrode portion 10 can be reliably connected regardless of the touch position P. .
In addition, since the linear protrusion 16 is formed so as to extend substantially in the center in the width direction D2 in the detection region R, it corresponds to the center of the resistor electrode portion 9 and the detection electrode portion 10 in the base material 5b. The linear projection 16 can be pressed against the portion, and the resistor electrode section 9 and the detection electrode section 10 can be more reliably connected.
Further, since one linear protrusion 16 is arranged in the detection region R, it is possible to suppress the pressing force due to the touch from being diffused to a plurality of places, as compared to a case where a plurality of linear protrusions are arranged, for example. Thus, the resistor electrode section 9 and the detection electrode section 10 can be more reliably connected.

  Here, it is preferable that the linear protrusion 16 be formed to have a semicircular cross section. Thereby, the deformation of the linear projection 16 due to the pressing of the base member 5b can be suppressed, and the base member 5b can be continuously pressed at a constant pressure. In addition, the linear protrusion 16 is preferably formed to be thin and low in height, for example, can be formed to have a height of 0.2 mm.

In this way, when the resistor electrode portion 9 corresponding to the touch position P and the detection electrode portion 10 are connected, as shown in FIG. 1, the potential of the resistor 6 pulled out from the resistor electrode portion 9 becomes The measurement is performed by the measurement unit 3 via the detection terminal 12. At this time, since the plurality of resistor electrode portions 9 are formed so as to intermittently extract the potential of the resistor 6, the potential at the touch position P can be measured with high accuracy as a value different from other potentials. it can.
The potential of the resistor 6 measured by the measuring unit 3 is output from the measuring unit 3 to the calculating unit 4, and the calculating unit 4 calculates the touch position P based on the potential of the resistor 6.

  According to the present embodiment, the linear projecting portions 16 are arranged so as to extend from the inner surface of the cover plate 15 and extend in a direction orthogonal to the plurality of resistor electrode portions 9 and the plurality of sensing electrode portions 10. The pressing force when the cover plate 15 is touched can be transmitted in the arrangement direction D1 without diffusing in a planar manner, and the resistor electrode section 9 corresponding to the touch position P and the detection electrode section 10 are securely connected. Thus, the touch position P can be detected with high accuracy.

Embodiment 2
In Embodiment 1 described above, the posture of the cover plate 15 is changed so as to be curved in response to a touch, but the posture is changed so that the linear protrusion 16 is partially pressed against the base material 5b. It is only necessary to be able to make it possible, and it is not limited to this.
For example, as shown in FIG. 3, an elastic support portion 21 can be provided instead of the fixing portion 17b of the first embodiment.

  The elastic support portion 21 elastically supports the cover plate 15, and is disposed so as to elastically connect the cover plate 15 and the base member 5b. The elastic support portion 21 is disposed along the edge of the cover plate 15 so as to surround the linear protrusion 16. The elastic support portion 21 can be made of, for example, urethane.

  With such a configuration, when the outer surface 15a of the cover plate 15 is touched with a finger as shown in FIGS. 4A and 4B, the cover plate 15 is The posture is changed so as to be slightly curved while being elastically moved toward the material 5b. Accordingly, the linear protrusion 16 arranged on the cover plate 15 also bends while moving toward the base 5b, and a portion of the linear protrusion 16 corresponding to the touch position P is pressed against the base 5b.

  As described above, since the elastic support portion 21 changes the posture of the cover plate 15 so as to move toward the base material 5b, the linear projecting portion 16 can be securely attached to the base material 5b only by slightly bending the cover plate 15. Can be pressed. Therefore, for example, even when the cover plate 15 is made of a material having high rigidity, the linear protrusion 16 can be reliably pressed against the base material 5b.

  In this way, the base member 5b against which the linear protrusion 16 is pressed is curved toward the base member 5a together with the touch electrode unit 13, and the resistor electrode unit 9 and the detection electrode unit 10 corresponding to the touch position P are The connection is made by the touch electrode unit 13.

  According to the present embodiment, since the elastic support portion 21 is arranged so as to elastically connect the cover plate 15 and the base member 5b, the posture of the cover plate 15 is moved to the base member 5b side. The linear projection 16 can be reliably pressed against the base material 5b only by slightly bending the cover plate 15.

Embodiment 3
In the second embodiment, the elastic support portion 21 is disposed so as to elastically connect the cover plate 15 and the base member 5b. It is only necessary to be able to move elastically, and the present invention is not limited to this.
For example, as shown in FIG. 5, a cover plate 31 may be provided instead of the cover plate 15 of the second embodiment, and an elastic support portion 32 may be provided instead of the elastic support portion 21.

  The cover plate 31 has a long plate shape and is made of a material having higher rigidity than the base materials 5a and 5b. Here, the cover plate 31 has a larger area than the base materials 5 a and 5 b, and is arranged such that an edge thereof is opposed to an edge of the fixed plate 14.

  The elastic support portion 32 elastically supports the cover plate 31 and is disposed so as to elastically connect between the cover plate 31 and the edge of the fixed plate 14. Further, the elastic support portion 32 is arranged so as to surround the base members 5 a and 5 b together with the linear protrusion 16. Here, since the elastic support portion 32 is disposed between the cover plate 31 and the fixed plate 14, the elastic support portion 32 is formed to be thicker than the elastic support portion 21 of the second embodiment. Accordingly, since the elastic support portion 32 has a large deformation amount, the cover plate 31 can be largely moved to the base material 5b side. The elastic support portion 32 can be made of, for example, urethane.

  With such a configuration, when the outer surface of the cover plate 31 is touched with a finger, the posture of the cover plate 31 can be significantly changed. For example, as shown in FIGS. 6A and 6B, when the outer surface 31a on the side of the edge 33a of the pair of edges 33a and 33b of the cover plate 31 is touched, the elastic support 32 becomes the edge 33a. The side is largely contracted, and accordingly, the posture of the cover plate 31 is changed so that the edge 33a is lower than the edge 33b. That is, the elastic support portion 32 connects the cover plate 31 and the fixed plate 14 such that the cover plate 31 is greatly inclined toward the base material 5b in response to the touch. Thereby, the posture of the cover plate 31 is changed so that the cover plate 31 bends while being greatly inclined in response to the pressing of the touch. The linear protrusion 16 also curves while being greatly inclined toward the base material 5b according to the change in the posture of the cover plate 31, and the portion of the linear protrusion 16 corresponding to the touch position P is pressed against the base material 5b. Can be

As described above, since the elastic support portion 32 changes the attitude of the cover plate 31 so as to be greatly inclined, it is possible to reliably press the linear projecting portion 16 against the base material 5b without substantially bending the cover plate 31. it can. Therefore, even when the cover plate 31 is made of a material having higher rigidity, the linear protrusion 16 can be reliably pressed against the base material 5b.
Further, the elastic support portions 32 are arranged so as to surround the linear projecting portions 16, that is, are arranged so as to sandwich the linear projecting portions 16 in the width direction D2. Accordingly, even when the user touches a position shifted in the width direction D2 from the linear protrusion 16, the posture of the cover plate 31 changes so as to also incline in the width direction D2, so that the base material 5b can be reliably pressed. it can.

  According to the present embodiment, since the elastic support portion 32 is disposed so as to elastically connect the cover plate 31 and the fixed plate 14, the cover plate 31 is largely inclined in response to a touch pressure. The linear projection 16 can be reliably pressed against the base material 5b without substantially bending the cover plate 31.
