Description

Touch panel operation patch

The present invention relates to a touch panel operation patch that can be used in all touch panel methods.

In recent years, touch panels have mainly dealt with a large number of highly publicized machines, such as ATMs and vending machines of financial institutions such as banks (especially ticket machines for train stations or restaurants), until mobile phones and mobile information terminals. (PDA), digital audio players, mobile game consoles, photocopiers, fax machines, car navigation systems, personal computers and other digital information machines are used in many aspects.

Generally speaking, the touch panel adopts a resistive film, a sonic pulse wave, a surface acoustic wave, an infrared shading, a projected capacitor, an electromagnetic induction, and an image recognition. The basic principle of the touch panel is that in any way, the conductive (dielectric) body such as a conductive or dielectrically processed stylus can be applied to the surface of the touch panel by the operator's finger and the front end. Pressure is applied to sense the information of the position of the screen being touched, and then the information signal is output to the outside.

However, in the case of operating the touch panel with the operator's finger, although the pin point operation is relatively easy compared to when the stylus is used, the contact state between the finger and the panel changes due to the increase or decrease of the force, causing the position to deviate. Or the sebum or sweat of the operator's finger causes stains on the surface of the touch panel, and thus there is a problem of deterioration in operability. In addition, compared to the case of operating with a finger, the conventional Although the stylus is relatively difficult to cause stains on the surface of the touch panel, the front of the pen is mostly pointed, so that the surface of the touch panel, the surface of the touch panel itself, and the operability deterioration may be damaged during use.

A stylus pen for squeezing a stylus is disclosed in Japanese Laid-Open Patent Publication No. 2009-259062 (Patent Document 1). A glove-type stylus pen is disclosed in the document 2), and a ring-type stylus pen placed on a finger is disclosed in Japanese Laid-Open Patent Publication No. 2012-251271 (Patent Document 3).

Here, the stylus pen 100 of Patent Document 1 is composed of a finger-type jig 101 and a nib portion 102 attached to the distal end of the jig 101, and is placed on the finger as shown in Fig. 1 . Come up and use. In the case of the stylus of Patent Document 1, it is usually used by being placed on a finger, and it can be used with the feeling of a finger, and since the tip portion is circular, it is not easy to damage the surface of the touch panel. However, since the shape of the nib portion is limited and the principle of the conventional stylus type is adopted, the pin point operation of the touch panel may be difficult, for example, for an elderly person or a physically disabled person. The problem.

Further, the stylus of Patent Document 2 is also the same, and it is difficult for the touch point operation of the touch panel to be, for example, an elderly person or a physically disabled person. Further, in comparison with the stylus of Patent Document 1, although the stylus of Patent Document 2 is relatively close to the feeling of operating with a finger, since it is a glove type, it is easy to cause an error due to the roughness of the fiber or the like.

Further, in the conductive member covered by the covering member, the conductive member covered by the covering member causes the conductive member to act on the touch panel via the slit slit provided in the covering member, but since the contact portion is a slit slit, Therefore, for an elderly person or a physically handicapped person who is not familiar with the touch point operation of the touch panel, there is a concern that the operation is difficult.

The touch panel operation patch of the present invention will be described below with reference to the drawings.

Fig. 2 is a schematic view showing a sectional structure of a touch panel operation patch of the present invention. The touch panel operation patch 1 of the present invention is composed of the conductive fiber layer 2 and the adhesive layer 3 provided on the conductive fiber layer 2.

First, the conductive fiber layer 2 will be described.

The conductive fiber constituting the conductive fiber layer 2 referred to in the present application means a conductive process for the fiber. As the fiber, a heat-resistant fiber such as a methyl polyamine fiber, a polyphenylene sulfide (PPS) fiber, a polyamidene fiber or a fluorine fiber, or an aliphatic polyaryl group such as nylon 6 or nylon 66 can be used. Amidoxime fibers, polyethylene terephthalate (PET) fibers, polytrimethylene terephthalate (PTT) fibers, polybutylene terephthalate fibers, aliphatic polyester fibers (for example, Toray Industries, Inc.) "SCIMA (registered trademark)", etc.), aromatic polyester fiber, polyacrylonitrile (PAN) fiber, PAN carbon fiber, PAN-vinyl chloride copolymer fiber, polyethylene fiber, polypropylene fiber, polyvinylidene Fiber, polyvinyl alcohol fiber, polyvinyl chloride fiber, polyvinylidene chloride fiber, polyurethane fiber, polytetrafluoroethylene (PTFE) fiber, PBT (polyparaphenylene bisthiazole) fiber and PBO (poly-p-benzoene double Various fibers such as PBZ fibers, heterocyclic polymer fibers, cellulose (natural, regenerated, acetic acid, etc.) fibers, protein fibers, glass fibers, carbon fibers, alumina fibers, and boron fibers. Further, the shape of the fiber filaments may be either monofilament or multifilament. Further, even if one of the above fibers is sufficient, it is also possible to combine two or more fibers for blending.

The selection of the fiber can be appropriately selected according to the use environment. However, in consideration of heat resistance and strength of the patch for operation of the touch panel, methyl polyamine fiber and polyphenylene sulfide are preferable. (PPS) heat-resistant fibers such as fibers, polyimine fibers, and fluorine fibers.

Next, in the case of the conductive processing performed by the fiber, a conventional technique in which metal or black lead is uniformly dispersed in the fiber and the surface of the fiber is covered with a metal or a conductive resin may be used (for example, refer to Japanese Patent No. Bulletin 4575583). Further, the conductive processing may be performed before or after the formation of the conductive fiber layer.

Next, the shape of the conductive fiber layer 2 can be from a plush fabric, a terry cloth, a meltblown or a spunbonded woven fabric, a non-woven fabric, or a stretchable woven fabric, a cotton fabric, a polyester-nylon blend fabric, an acrylic fabric. Wool fabric, crepe fabric, acetate fabric, or fabric called polyurethane fabric, or polyurethane/polyvinyl chloride synthetic leather fabric, etc., are selected. The reason why the cloth is the shape of the conductive fiber layer 2 is to consider the slidability, abrasion resistance, peeling property, and the like with the surface of the touch panel. Further, the hole size (gap) when forming a cloth of this type is not particularly limited.

Further, the thickness of the conductive fiber layer 2 is preferably 0.25 to 5.0 mm. When it is less than 0.25 mm, the deterioration of the aforementioned fitting portion 2 will be advanced in use. In addition, when it is 5.0 mm or more, it is easy to cause an error when the touch panel is operated.

Even in the above-described aspect, the conductive fiber layer 2 is also established, but the conductive fiber layer 2 may be subjected to surface processing. The surface processing described herein is used to improve the slidability and wear resistance of the touch panel operation patch of the present invention, the peeling property and the release property in the fixing between the sleeve portion and the touch panel surface. Sex. Further, the surface processing may be in the form of coating the surface of the conductive fiber layer 2 with a coating material for surface processing. In addition, since the coating material must maintain the slidability, abrasion resistance, peeling property, and release property previously described, and also must maintain the conductivity of the conductive polyoxyxene rubber, it is more suitable for conductivity. A resin containing a fluororesin or a conductive polythiophene-based polymer as a main component, a polyetheretherketone (PEEK) resin, an acrylic resin, or the like. However, in the case of the above-described conductive processing, a method of covering the surface of the fiber with a conductive resin is used, and surface processing is also included.

Further, in the conductive fiber layer, since the fiber is used, it is possible to further dye the fiber fabric, apply a pattern, design, or the like. In addition to this, an additive such as a deterioration preventing agent, a softening agent, or a flame retardant may be added or applied as appropriate.

Next, the adhesive layer 3 will be described.

The adhesive layer 3 is preferably insulative in order to prevent electric shock or the like from the user. As the material used for the pressure-sensitive adhesive layer 3, a cyanoacrylate-based adhesive, an acrylic resin-based adhesive, a polyvinyl alcohol-based, a rubber or latex-based adhesive, a polyoxygen-based adhesive, or the like can be used. Among them, a cyanoacrylate-based adhesive is preferred. The cyanoacrylate adhesive can be used as a surgical adhesive. In addition, when the temporary adhesiveness, re-peelability, and complete adhesiveness of the finger or the like of the touch panel operation of the present invention are reviewed, the above-mentioned adhesive can be appropriately selected. Further, in addition to the adhesive, the adhesive layer 3 may be used in combination with an insulating double-sided tape or the above-described adhesive together with a polymer substrate (for example, polypropylene or the like). Further, the adhesive layer 3 can be formed by a known technique.

Further, the total thickness of the touch panel operation patch 1 is about 0.3 to 10 mm. Further, the ratio of the thickness between the conductive fiber layer 2 and the adhesive layer 3 is premised on the thickness of the touch panel operation patch 1 of 0.3 to 10 mm as long as it conforms to the conductive fiber previously described. The numerical range of the thickness of the layer 2 is only required, and can be appropriately selected.

Further, when the touch panel operation patch of the present invention is used, the operation finger F is adhered to the adhesive layer 3 (see FIG. 3). FIG. 3 exemplifies the case of sticking to one finger F. However, in accordance with the size and operation of the touch panel, it can also be applied to all fingers and two fingers of one hand, and the position of the adhesive can be appropriately changed.

In addition, as shown in FIG. 4, the planar and three-dimensional shape of the touch panel operation patch 1 of the present invention can be processed into an ellipse, a cone, a rectangle or a square by a conventional technique such as press molding. For the shape of a quadrangle, a triangle, a gourd, or the like, a shape conforming to the size of the touch panel can be suitably used.

In the above, the touch panel operation patch of the present invention has been described. However, the embodiment of the present invention is not limited thereto, and may be implemented as various types without departing from the scope of the patent application and the contents described in the present specification.
