The pair of base materials 5a and 5b is a transparent insulating base material having a long shape. Moreover, the base materials 5a and 5b have flexibility and are thinly formed in a film shape. The base materials 5a and 5b can be formed from, for example, a resin material such as polyethylene terephthalate.
The resistor 6 has a relatively high resistance value and is arranged so as to extend linearly in the longitudinal direction of the substrate 5a. The resistor 6 is formed with a constant thickness so as to have a uniform resistance distribution in the longitudinal direction.

The detection wiring portion 8 is arranged so as to extend linearly from the detection terminal 12 along the resistor 6. The detection wiring part 8 has a resistance value lower than that of 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 intervals. Specifically, the resistor electrode portion 9 is formed so as to extend in a comb shape from the resistor 6 toward the detection wiring portion 8. That is, the resistor electrode portions 9 have the same elongated shape and are arranged at equal intervals along the resistor 6. In addition, each of the resistor electrode portions 9 has a resistance value much lower than that of the resistor 6 so as to have substantially the same potential as that of a connection portion with the resistor 6, that is, no potential gradient is generated. For example, the resistor electrode unit 9 can be made of silver or the like.

  The plurality of detection electrode portions 10 are connected to the detection wiring portion 8 at intervals. Specifically, the detection electrode unit 10 is formed so as to extend between the resistor electrode units 9 in a comb-tooth shape from the detection wiring unit 8 toward the resistor 6. That is, the detection electrode portions 10 have the same elongated shape and are arranged at equal intervals along the detection wiring portion 8. Further, the detection electrode unit 10 has substantially the same resistance value as that of the resistor electrode unit 9, and can be made of, for example, silver.

The touch electrode portion 14 is formed so as to cover the plurality of resistor electrode portions 9 and the plurality of detection electrode portions 10. That is, the touch electrode portion 14 is formed so as to spread on the other substrate 5b in a planar shape. For this reason, the touch electrode portion 14 is locally curved when the touch position P is touched from the outside of the other base material 5b, and the resistor electrode portion 9a corresponding to the touch position P is changed to the detection electrode portion 10a. Connect electrically. Thereby, the resistor electrode part 9a is connected to the detection wiring part 8 through the detection electrode part 10a. The touch electrode portion 14 has substantially the same resistance value as that of the resistor electrode portion 9 and can be made of, for example, silver.
In addition, the some resistor electrode part 9, the some detection electrode part 10, and the touch electrode part 14 comprise the connection part in this invention.

The power supply terminals 11a and 11b are for supplying power to the resistor 6, and the power supply terminal 11a is connected to the resistor wiring part 7a and the power supply terminal 11b is connected to the resistor wiring part 7b. Thus, the power supply terminals 11a and 11b are connected to the resistor 6 via the resistor wiring portions 7a and 7b.
The detection terminal 12 is connected to the detection wiring portion 8 in order to measure the potential of the resistor electrode portion 9a corresponding to the touch.

The power feeding unit 2 is connected to the power feeding terminals 11a and 11b and feeds power to the resistor 6 via the power feeding terminals 11a and 11b.
The measurement unit 3 is connected to the detection terminal 12 and measures the potential of the resistor electrode unit 9a according to the touch 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 a measured by the measurement unit 3.

Next, the configuration of the resistor electrode unit 9, the detection electrode unit 10, and the touch electrode unit 14 will be described in detail.
As shown in FIG. 2A, the resistor electrode portion 9 and the detection electrode portion 10 disposed on the base material 5a and the touch electrode portion 14 disposed on the base material 5b are opposed to each other with a predetermined gap. Has been placed. In addition, a spacer (not shown) for forming a gap is disposed between the one base material 5a and the other base material 5b.
Here, the protection electrode 15a, 15b, and 15c are arranged to cover the resistor electrode unit 9, the detection electrode unit 10, and the touch electrode unit 14, respectively. These protection parts 15a-15c are for suppressing migration, and can be composed of, for example, carbon, a mixture of carbon and silver, or the like. In addition, it is preferable that the carbon used by the protection parts 15a-15c has a resistance value one digit or more smaller than the carbon used by the resistor 6.

  Thus, by touching the outside of the other base material 5b as shown in FIG. 2 (b) by arranging the touch electrode portion 14 to face the resistor electrode portion 9 and the detection electrode portion 10, The touch electrode unit 14 is locally bent together with the other base material 5b, and the resistor electrode unit 9a and the detection electrode unit 10a corresponding to the touch are connected by the touch electrode unit 14.

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 11 a and 11 b, and a potential distribution is formed in 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 the connection portion with the resistor 6. For this reason, the plurality of resistor electrode portions 9 are arranged in the longitudinal direction of the substrate 5 a 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 touch position P is touched from the outside of the other base material 5b, the resistor electrode portion 9a and the detection electrode portion 10a corresponding to the touch are touched. The electrodes 14 are connected. As a result, the potential of the resistor 6 drawn out from the resistor electrode portion 9 a is measured by the measuring unit 3 through the detection terminal 12.

  At this time, the touch electrode unit 14 is not connected to the resistor 6 in response to the touch, but is connected to the resistor electrode unit 9a. When the touch electrode unit 14 is directly connected to the resistor 6 having a high resistance value and presses the resistor 6, the potential measured by the measuring unit 3 may vary depending on the pressing force. Therefore, the touch electrode unit 14 is connected to the resistor electrode unit 9a, thereby suppressing the fluctuation of the potential measured by the measuring unit 3 and accurately measuring the potential of the resistor 6 via the resistor electrode unit 9a. be able to. Moreover, since the detection electrode part 10 and the detection wiring part 8 have a very low resistance value with respect to the resistor 6, it can measure accurately, without changing the electric potential of the resistor electrode part 9a.

The plurality of resistor electrode portions 9 are formed so as to intermittently extract the potential of the resistor 6. For this reason, the potential at the touch position P can be clearly distinguished from the surrounding potential, and the touch position P can be detected with high reproducibility.
Furthermore, since it has a simple structure in which the resistor electrode unit 9, the detection electrode unit 10, and the touch electrode unit 14 are arranged with respect to the resistor 6, the touch panel 1 can be formed in a small size.
In this way, the potential of the resistor 6 measured by the measurement unit 3 is output from the measurement unit 3 to the calculation unit 4. The calculation unit 4 calculates the touch position P based on the input potential of the resistor 6.

In addition, when detecting the two touch positions P, the calculation unit 4 can calculate the touch positions by a conventional method used in a resistive touch panel. For example, potential information corresponding to a combination of two touch positions is stored in advance as a lookup table, and the two touch positions are calculated by searching the lookup table based on the potential measured by the measurement unit 3. be able to.
Further, when the finger to be touched is slid in the direction along the resistor 6, the calculation unit 4 detects a continuous potential change via the measurement unit 3, and the touch position is determined based on the potential change. P is calculated sequentially. As a result, a slide operation for sliding a finger can be recognized.

  According to the present embodiment, the resistor 6 has a resistance value lower than that of the resistor 6 and is connected to the resistor 6 at intervals from each other, and the resistor electrode 9a corresponding to the touch is provided. Is electrically connected to the detection wiring portion 8, the potential of the resistor 6 can be measured without directly pressing the resistor 6 according to the touch, and the touch position P can be detected accurately.

Embodiment 2
In the first embodiment, the resistor 6 is arranged so as to extend linearly. However, the resistor 6 only needs to be arranged so as to extend linearly, and is not limited to a linearly extending one.
For example, as shown in FIG. 3, a resistor 21, a detection wiring unit 22, and a touch electrode unit 23 can be arranged instead of the resistor 6, the detection wiring unit 8, and the touch electrode unit 14 of the first embodiment. .

The resistor 21 is arranged on one base so as to extend in a circular shape, and one end is connected to the power supply terminal 11a and the other end is connected to the power supply terminal 11b. As in the first embodiment, the resistor 21 has a relatively high resistance value and is formed with a constant thickness so as to have a uniform resistance distribution in the longitudinal direction.
The detection wiring part 22 is arranged on one base so as to extend circularly inside the resistor 21, and one end part is connected to the detection terminal 12.

  The touch electrode portion 23 is disposed on the other base so as to cover the plurality of resistor electrode portions 9 and the plurality of detection electrode portions 10. That is, the touch electrode portion 23 is disposed so as to extend in a circular shape between the resistor 21 and the detection wiring portion 22.

With such a configuration, when the touch position P is touched, the resistor electrode unit 9 a and the detection electrode unit 10 a corresponding to the touch are connected by the touch electrode unit 23. Thereby, the electric potential of the resistor 21 can be measured by the measurement unit via the resistor electrode unit 9a. Here, since the resistor 21 is arranged so as to extend in a circular shape, for example, it is possible to detect the movement of a finger that is slid in a circle along the resistor 21.
According to this Embodiment, since the resistor 21 is arrange | positioned so that it may extend circularly, the touch panel 1 can be operated circularly.

Embodiment 3
In the second embodiment, the touch position P is detected between the resistor 21 and the detection wiring unit 22. However, a resistor is further arranged inside the detection wiring unit 22 to detect the touch position P at a plurality of locations. You can also
For example, as shown in FIG. 4, the resistor 31, the resistor 32, the plurality of resistor electrode portions 33, and the plurality of detection electrode portions 34 can be newly disposed in the second embodiment.

  The resistor 31 is arranged so as to extend in a circular shape inside the detection wiring part 22, and one end is connected to the resistor 32 and the other end is connected to the power supply terminal 11 a. Further, like the resistor 21, the resistor 31 is formed with a constant thickness so as to have a uniform resistance distribution.

The resistor 32 is disposed so as to extend linearly from the resistor 21 toward the resistor 31. One end of the resistor 32 is connected to one end of the resistor 21 and the other end is connected to the resistor 31. It is connected to one end of the. The resistor 32 is formed thinner than the resistors 21 and 31 so that the resistance value is larger than that of the resistors 21 and 31. The resistor 32 is formed with a constant thickness so as to have a uniform resistance distribution in the longitudinal direction.
As described above, the resistor 21, the resistor 31, and the resistor 32 are connected to each other and formed into one continuous curve.

The plurality of resistor electrode portions 33 are connected to the resistor 31 at intervals. Specifically, the plurality of resistor electrode portions 33 are formed so as to extend in a comb shape from the resistor 31 toward the detection wiring portion 22. Further, the plurality of resistor electrode portions 33 have a resistance value much lower than that of the resistor 31 so as to have substantially the same potential as the resistor 31.
The plurality of detection electrode portions 34 are connected to the inside of the detection wiring portion 22 with a space therebetween. Specifically, the plurality of detection electrode portions 34 are formed so as to extend in a comb shape between the plurality of resistor electrode portions 33 from the detection wiring portion 22 toward the resistor 31. Further, the plurality of detection electrode portions 34 have substantially the same resistance value as that of the resistor electrode portion 33.

The touch electrode unit 23 is arranged so as to cover the plurality of resistor electrode units 9, the plurality of detection electrode units 10, the plurality of resistor electrode units 33, and the plurality of detection electrode units 34. That is, the touch electrode portion 23 is disposed so as to extend between the resistor 21 and the resistor 31 in a circular shape.
In this way, the detection region S1 for detecting the touch position is formed between the detection wiring unit 22 and the resistor 21, and the detection region S2 for detecting the touch position is formed between the detection wiring unit 22 and the resistor 31. be able to.

With such a configuration, when the detection region S1 is touched, the resistor electrode unit 9 and the detection electrode unit 10 corresponding to the touch are connected by the touch electrode unit 23, and when the detection region S2 is touched, the touch is performed. The resistor electrode part 33 and the detection electrode part 34 according to the above are connected by the touch electrode part 23. For example, the detection area S1 can be used to detect the movement of a finger that is slid in a circle, and the detection area S2 can be used as an enter key.
Here, the resistor 32 is formed thinner than the resistors 21 and 31 so that the resistance value is increased, and the potential difference between the resistor 21 and the resistor 31 can be increased. Thereby, the potential when the detection area S1 is touched and the potential when the detection area S2 is touched can be clearly distinguished, and the touch position can be accurately detected.

  According to the present embodiment, since the resistor 31 is arranged inside the resistor 21 to form the two detection regions S1 and S2, the functionality of the touch panel 1 can be improved.

Embodiment 4
In the above first to third embodiments, the plurality of resistor electrode portions and the plurality of detection electrode portions are formed so as to extend in a straight line, but it is only necessary that they can be connected to each other by the touch electrode portion. It is not restricted to what extends.
For example, as shown in FIG. 5, a plurality of detection electrode portions 41 can be arranged in place of the plurality of detection electrode portions 10 of the second embodiment.

  The plurality of detection electrode portions 41 have branch portions 42 formed so as to extend in a branch shape. Here, since the plurality of resistor electrode portions 9 and the plurality of detection electrode portions 41 are arranged so as to extend in different directions, a narrow region G1 having a narrow mutual interval is formed in the vicinity of the base end portion of the detection electrode portion 41. A wide region G <b> 2 is formed in the vicinity of the tip of the detection electrode portion 41 that is formed and is widely spaced from each other. The branch portion 42 is formed so as to extend to the wide region G <b> 2 in the vicinity of the distal end portion of the detection electrode portion 41. For this reason, the resistor electrode part 9 and the detection electrode part 41 can be reliably connected by the touch electrode part 23, and a touch position can be reliably detected by suppressing the occurrence of a dead zone.

According to the present embodiment, the plurality of detection electrode portions 41 have the branch portions 42 formed so as to extend in a branch shape in the vicinity of the distal end portion having a wide interval with the resistor electrode portion 9. It is possible to reliably connect to the resistor electrode portion 9 via 23.
In addition, the branch part 42 may be formed in the resistor electrode part 9. For example, when the distance between the resistor electrode part 9 and the detection electrode part 41 is wide in the vicinity of the distal end part of the resistor electrode part 9, A branch portion 42 can be formed in the vicinity of the tip portion.

Embodiment 5
In the above-described Embodiments 2 to 4, the resistor is formed so as to extend in a circular shape. However, the resistor is not limited to a circular shape as long as it can be arranged to extend in a curved shape.
For example, as shown in FIG. 6, a resistor 51, a detection wiring portion 52, and a touch electrode portion 53 can be arranged instead of the resistor 6, the detection wiring portion 8, and the touch electrode portion 14 of the first embodiment. .

The resistor 51 is arranged on one base so as to meander and extend, and one end is connected to the power supply terminal 11a and the other end is connected to the power supply terminal 11b.
The detection wiring part 52 is arranged on one base so as to meander and extend along the resistor 51, and one end thereof is connected to the detection terminal 12.
The touch electrode portion 53 is disposed on the other base so as to cover the plurality of resistor electrode portions 9 and the plurality of detection electrode portions 10. That is, the touch electrode portion 53 is disposed so as to meander between the resistor 51 and the detection wiring portion 52.

Thus, by arranging the resistor 51 so as to meander, the detection region S where the touch position is detected can be formed so as to meander and extend.
With such a configuration, for example, when a finger is slid along the detection region S, the plurality of resistor electrode portions 9 and the plurality of detection electrode portions 10 are sequentially connected and moved along the detection region S. Can be detected.
According to the present embodiment, since the resistor 51 is arranged to meander and extend, the touch panel 1 can be operated to meander.

In the present embodiment, the resistor 51 is formed with two curved portions that change the meandering direction so as to bend, and the resolution of the detection region S varies depending on the curvature of the curved portion. Yes. For this reason, it is preferable to make the resolution of the detection region S uniform.
For example, as shown in FIG. 7, a resistor 54a, a resistor 54b, a detection wiring portion 55a, and a detection wiring portion 55b can be arranged in place of the resistor 51 and the detection wiring portion 52 described above. The detection region S has two direction changing portions T1 and T2 that change the meandering direction so as to be curved.

Resistors 54a and 54b are arranged so as to be along outer peripheries having a long length in direction change portions T1 and T2 of detection region S, respectively. That is, the resistor 54a is arranged along one edge of the detection region S where the outer peripheral portion of the direction changing portion T1 is formed, and the resistor 54b is arranged in the detection region S where the outer peripheral portion of the direction changing portion T2 is formed. Arranged along the other edge. And the connection part 56 is arrange | positioned so that the detection area | region S may be crossed, and the resistor 54a and the resistor 54b are connected by this connection part 56. FIG.
Here, the connecting portion 56 has a resistance value much lower than that of the resistors 54a and 54b so as not to greatly change the potential of the resistors 54a and 54b. For example, the connecting portion 56 can be made of silver or the like.

  The detection wiring portions 55a and 55b are arranged along the inner peripheral portion having a short length in the direction changing portions T1 and T2 of the detection region S, respectively. That is, the detection wiring portion 55a is arranged along the other edge of the detection region S where the inner peripheral portion of the direction changing portion T1 is formed, and the detection wiring portion 55b is formed of the inner peripheral portion of the direction changing portion T2. It is disposed along one edge of the detection region S. The detection wiring portions 55 a and 55 b are connected to the detection terminal 12 at their respective ends.

In this way, the resistors 54a and 54b are arranged so that the lengths are the same in the direction change unit T1 and the direction change unit T2, and the finger moves at the same speed in the direction change unit T1 and the direction change unit T2. In this case, the touch position can be detected with the same movement amount, and the resolution for detecting the touch position can be made uniform.
Furthermore, since the resistors 54a and 54b are arranged along the outer peripheral portions of the direction changing portions T1 and T2, the resolution for detecting the touch position can be improved, and the touch position can be detected accurately.

  Further, as shown in FIG. 8, in the touch panel 1 of FIG. 6, a branch-shaped portion 57a is disposed in the vicinity of the distal end portion of the detection electrode portion 10 located in the direction changing portion T1, and the resistor electrode is located in the direction changing portion T2. By disposing the branch portion 57b in the vicinity of the tip portion of the portion 9, the resolution of the direction changing portions T1 and T2 can be made uniform.

  Here, the resistor 51 is disposed along only one edge of the detection region S. That is, the direction change part T1 has the resistor 51 arranged longer than the direction change part T2. And the branch part 57a is arrange | positioned in the tip part vicinity of the detection electrode part 10 located in direction change part T1, and the branch part 57b is arrange | positioned in the tip part vicinity of the resistor electrode part 9 located in direction change part T2. ing.

As a result, the branch portion 57a improves the amount of connection between the resistor electrode unit 9 and the detection electrode unit 10 in a region close to the resistor 51, thereby reducing the resolution for detecting the touch position in the direction changing unit T1. Can do.
On the other hand, the branch portion 57b improves the amount of connection between the resistor electrode unit 9 and the detection electrode unit 10 in a region far from the resistor 51, so that the resolution for detecting the touch position in the direction changing unit T2 can be increased. .

  Thus, in the direction change part T1 in which the resistor 51 is arranged long, the branch-like part 57a is arranged in the vicinity of the tip of the detection electrode part 10, and in the direction change part T2 in which the resistor 51 is arranged short, the resistor electrode By disposing the branch portion 57b in the vicinity of the tip portion of the portion 9, the resolution of the direction changing portions T1 and T2 can be made uniform.

In the above-described fifth embodiment, the detection area S can also function as a plurality of switches.
For example, as shown in FIG. 9, instead of the resistor 51, the detection wiring unit 52, and the touch electrode unit 53 in the touch panel 1 of FIG. 6, a resistor 61, a detection wiring unit 62, and a touch electrode unit 63 may be arranged. it can.

The resistor 61 is formed to meander so as to have opposing portions in the same plane. Specifically, the resistor 61 extends in a straight line in a predetermined direction X and has three resistor-facing portions arranged so as to sequentially face each other and a resistor 61 extending in a straight line in a direction Y orthogonal to the direction X. And two resistor connecting portions for connecting the body facing portions. Thereby, the resistor 61 is formed in the meandering shape which has a corner | angular part.
The detection wiring part 62 includes three detection opposing parts that are linearly extended in the direction X and arranged so as to sequentially face each other, and two detection connection parts that extend linearly in the direction Y and connect the detection opposing parts. Have. Thereby, the detection wiring part 62 is formed in the meandering shape which has a corner | angular part.
The touch electrode unit 63 is arranged in a meandering shape between the resistor 61 and the detection wiring unit 62 so as to cover the plurality of resistor electrode units 9 and the plurality of detection electrode units 10.

Accordingly, the detection region S extends in a straight line in the direction X and is connected to the three detection facing parts L1 to L3 arranged so as to face each other in a straight line, and extends in a straight line in the direction Y to connect the detection facing parts L1 to L3. The two direction changing portions T1 and T2 are formed.
With such a configuration, for example, a plurality of switch portions W1 to W6 can be provided in the detection facing portions L1 to L3 of the detection region S. A plurality of switch units W1 to W6 can be provided on one touch panel 1 by detecting touches on the switch units W1 to W6, respectively.

The non-detection region N preferably has a width of one finger or more in the direction Y, and can be formed with a width of, for example, about 18 mm or more. Thereby, operation of switch part W1-W6 provided in different detection opposing parts L1-L3 can be detected reliably.

  According to the present embodiment, since the resistor 61 is arranged so as to meander and extend, for example, a plurality of switches W1 to W6 are provided on the detection facing portions L1 to L3, and various functions are provided on one touch panel 1. Can be provided.

Embodiment 7
In the above second to sixth embodiments, the movement of the finger that is slid in the direction along the resistor is detected, but the movement of the finger in the direction that intersects the resistor can also be detected.
For example, as shown in FIG. 10, a resistor 71, a detection wiring part 72, and a touch electrode part 73 can be arranged instead of the resistor 61, the detection wiring part 62, and the touch electrode part 63 of the sixth embodiment. .

The resistor 71 is formed to meander so as to have opposing portions in the same plane. Specifically, the resistor 71 extends linearly in the direction X and is connected to the four resistor opposing portions arranged so as to sequentially face each other and the resistor opposing portion extending linearly in the direction Y 3. It has two resistor connecting portions and is formed in a meandering shape having corner portions.
The detection wiring parts 72 are arranged so as to be along the four detection opposing parts arranged along the four resistor opposing parts of the resistor 71 and the three resistor connecting parts of the resistor 71, respectively. And three detection connecting parts for connecting the opposing parts.
The touch electrode unit 73 is arranged in a meandering shape between the resistor 71 and the detection wiring unit 72 so as to cover the plurality of resistor electrode units 9 and the plurality of detection electrode units 10.

As a result, the detection region S extends linearly in the direction X and is connected to the four detection facing portions L1 to L4 arranged so as to sequentially face each other, and the detection facing portion L1 extends linearly in the direction Y and connects the detection facing portions L1 to L4. The three direction changing portions T1 to T3 are formed in a meandering shape having corner portions.
At the corners where the resistors 71 are arranged longer in the direction changing portions T1 to T3, the detection electrode portions 10 having branch portions formed in the vicinity of the tip portions are arranged more than the resistor electrode portions 9 and touched. The resolution for detecting the position is lowered. Further, at the corners where the resistors 71 are shortly arranged in the direction changing portions T1 to T3, the resistor electrode portions 9 each having a branch-like portion formed in the vicinity of the tip portion are arranged more than the detection electrode portions 10 and touched. The resolution to detect the position is increased. Thereby, similarly to the touch panel 1 shown in FIG. 8 of the fifth embodiment, the resolution of the corners of the direction changing portions T1 to T3 can be made uniform.

  Here, the plurality of resistor electrode portions 9 are arranged over the entire length of the resistor 71 including the four resistor-facing portions. For this reason, the detection facing portions L1 to L4 of the detection region S are formed along the four resistor facing portions, respectively. As described above, when the detection facing portions L1 to L4 are arranged in the direction Y, when the finger is slid so as to cross the resistor facing portion, the finger is moved to the detection facing portions L1 to L4 having different detection areas S. Touched. For example, twelve touch positions P1 to P12 are set in the detection facing portions L1 to L4. When a finger is slid from the touch position P1 of the detection facing portion L1 to the touch position P4 of the detection facing portion L2, different potentials can be measured at the touch position P1 and the touch position P4. The movement of the finger to P4 can be detected.

  Further, three non-detection regions N having the same width are formed between the detection facing portions L1 to L4. For this reason, when the finger is slid in a direction crossing the resistor 71, the finger crosses the non-detection region N. For example, when the finger is slid from the touch position P1 to the touch position P4, the potential measured by the measurement unit once becomes zero in the non-detection region N from the value of the touch position P1, and then becomes the value of the touch position P4. . For this reason, the movement of the finger from the touch position P1 to the touch position P4 can be clearly detected.

FIG. 11 shows a method for recognizing numbers 1 to 9 drawn with a finger as an example of detecting the movement of the finger.
When recognizing the number “1”, first, the potential of the touch position P2 or the touch position P3 is detected as the first detection. Next, the finger is slid from the touch position P2 or the touch position P3, and the potential at the touch position P5 is detected as the second detection. At this time, since the finger is slid so as to cross the non-detection region N, the touch position P5 can be reliably detected.

Subsequently, after the finger is slid from the touch position P5 and the potential of the touch position P8 is detected as the third detection, the potential of the touch position P10 or the touch position P11 is detected as the fourth detection. Thereby, it can be recognized that the number written with a finger is “1”.
Similarly, the numbers 1 to 9 drawn by the finger can be recognized by sequentially detecting the touch positions P1 to P12. By storing such a lookup table in the calculation unit, it is possible to easily calculate a number drawn with a finger.
Here, when a number can be reliably recognized in the middle of sequentially detecting the touch positions P1 to P12, the number may be fixed in the middle. For example, when recognizing the number “1”, the number can be determined when the touch position P8 of the third detection is detected.

  According to the present embodiment, since the plurality of resistor electrode portions 9 are arranged at the four resistor-facing portions facing each other in the resistor 71, the detection facing portions L1 to L4 of the detection region S are arrayed in the direction Y. be able to. For this reason, not only the movement of the touch position in the direction along the resistor 71 but also the movement of the touch position crossing the four resistor facing portions can be detected. Thereby, the touch panel 1 configured in a two-dimensional plane can be obtained. For example, a finger is slid, such as a flick operation that operates so as to remove a finger and a pinch operation that operates so as to change the interval between two fingers. Various operations can be performed.

In the present embodiment, the non-detection region N is formed between the detection facing portions L1 to L4 in the detection region S. However, if the movement of the touch position in the direction intersecting the resistor can be detected. Well, not limited to this.
For example, as shown in FIG. 12, a detection wiring part 74 can be arranged instead of the detection wiring part 72 in the touch panel 1 of FIG.

  The detection wiring portion 74 includes two detection facing portions 74 a and 74 b arranged so as to extend in the direction X between two adjacent resistor facing portions of the four resistor facing portions of the resistor 71. The detection facing portions 74 a and 74 b are arranged such that the plurality of detection electrode portions 10 extend toward the resistor 71 on both sides. The plurality of resistor electrode portions 9 are arranged so as to extend between the plurality of detection electrode portions 10 from the resistor 71 toward the detection facing portions 74a and 74b.

  Accordingly, the detection region S includes two detection facing portions L1 and L2 that extend linearly in the direction X across the detection facing portion 74a, and two detection facings that extend linearly in the direction X across the detection facing portion 74b. It is formed from the parts L3 and L4, the direction change part T which connects the detection opposing part L1 and L2, and the detection opposing part L3 and L4. And the non-detection area | region N is formed between the detection opposing part L3 and the detection opposing part L4.

  With such a configuration, 12 touch positions P1 to P12 can be set in the detection facing portions L1 to L4 as in the touch panel 1 of FIG. For example, when the finger is slid from the touch position P1 of the detection facing portion L1 to the touch position P4 of the detection facing portion L2, the potential measured by the measurement unit is continuously changed from the value of the touch position P1 to the value of the touch position P4. Change. Based on this continuous change in potential, the movement of the finger from the touch position P1 to the touch position P4 can be detected.

Thus, since the detection wiring part 74 arrange | positions the some detection electrode part 10 extended toward the resistor 71 on both sides of the detection opposing parts 74a and 74b, formation of the non-detection area | region N can be suppressed, The touch panel 1 can be reduced in size.
Note that the touch positions P1 to P12 can be reliably detected by forming the detection region S small and restricting the movement of the finger. For example, the detection region S can be formed in a size in which the length in the direction X is about 60 mm and the length in the direction Y is about 69 mm.

Here, a detection region S <b> 1 is formed between the resistor 81 and the detection wiring portion 82, and a detection region S <b> 2 is formed between the resistor 84 and the detection wiring portion 82. The detection region S <b> 1 detects the touch position based on intermittent potentials drawn from the resistor 81 by the plurality of resistor electrode portions 9. On the other hand, the detection region S2 detects the touch position based on the continuous potential of the resistor 84. For this reason, the detection area S1 and the detection area S2 can be used properly according to the purpose of detecting the touch position.
