JP5863141B2 - Touch panel operation sticker - Google Patents

Description

The present invention relates to a touch panel operation sticker that can be used in any touch panel system.

In recent years, touch panels have become highly public, such as ATMs of financial institutions such as banks, vending machines (especially vending machines such as railway stations and restaurants), mobile phones, personal digital assistants ( PDA), digital audio players, portable game machines, copiers, facsimile machines, car navigation systems, personal computers, and other digital information devices are used in various fields.

In general, a touch panel employs a system such as a resistive film, an acoustic pulse, an ultrasonic surface acoustic wave, an infrared shading, a projected capacitance, electromagnetic induction, and image recognition. The basic principle of a touch panel can be touched by applying pressure to the surface of the touch panel with a conductive (dielectric) material such as a touch pen with conductive or dielectric processing applied to the operator's fingers or tip in any method. The screen position information is detected and output as an information signal to the outside.

However, when the touch panel is operated with the fingers of the operator, the pinpoint operation is easier than when using the touch pen, but the contact state between the fingers and the panel changes due to the force, and the position is shifted. There is a problem that the surface of the touch panel is soiled by sebum and sweat of the finger of the person, thereby deteriorating operability. In addition, conventional touch pens are less susceptible to dirt on the touch panel surface than when operated with fingers, but the tip of the pen is often sharp, and the touch panel surface is damaged during use. There was a problem such as deterioration.

As a touch pen that has solved the above drawbacks, for example, a finger suck type touch pen is disclosed in Japanese Patent Laid-Open No. 2009-259062 (Patent Document 1), and a conventional touch pen is disclosed in Japanese Patent Laid-Open No. 2012-252525 (Patent Document 2). A touch pen in which the tip of the touch pen is softened is disclosed.

Here, as shown in FIG. 1, the touch pen 100 according to Patent Document 1 includes a finger suck type jig 101 and a pen tip portion 102 attached to the tip of the jig 101, and is used by being fitted to a finger. To do. In the case of the touch pen according to Patent Document 1, it is possible to use the touch pen as if using a finger by always wearing it on the finger, and the pen tip portion is rounded, so that the touch panel surface is hardly damaged. However, the shape of the pen tip is limited, and the conventional touch pen type is adopted in principle, so that pinpoint operation on the touch panel is difficult for elderly people or people with physical disabilities, for example. was there.

Similarly, in the touch pen according to Patent Document 2, a pinpoint operation on the touch panel is difficult for an elderly person or a person with a physical disability, for example. And although the touch pen which concerns on patent document 2 is a thing formed by metal-plating a silicone elastomer base material fundamentally, although the front-end | tip part was softened, there existed a problem that manufacturing cost would start.

First, the conductive silicone rubber layer 2 will be described.

The conductive silicone rubber constituting the conductive silicone rubber layer 2 is basically a mixture of silicone rubber and carbon black. Here, the silicone resin used as the raw material of the silicone rubber is not particularly limited in the structural formula, and may be either an addition polymerization type or a condensation reaction type. In addition, about silicone rubber formation, you may harden the said silicone resin using a vulcanizing agent.

Carbon black is mixed with the silicone resin before molding the silicone rubber, that is, before the silicone resin is cured by addition polymerization condensation reaction or by adding a vulcanizing agent. About the compounding quantity of carbon black, when the conductive silicone rubber layer 2 is 100 parts by weight, it is desirable to contain 40 to 50 parts by weight of carbon black, and the Shore A hardness (hardness) is 20 ° to 80 °. It is preferable that the angle is set to °. Here, the Shore A hardness is a hardness measured using a durometer A type based on JIS K 6253, and is mainly used for measuring the hardness of rubber. Furthermore, when the Shore A hardness (hardness) is 20 ° to 80 °, the volume resistivity of the conductive silicone rubber layer 2 is preferably adjusted to 2 to 500 Ω · cm. In addition, when the Shore A hardness of the conductive silicone rubber layer 2 is less than 20 °, there is a balance with the surface processing described later, but there is a possibility of sticking between the touch panel operation seal 1 and the touch panel surface. high. In addition, when the Shore A hardness is 80 ° or more, there is a balance with surface processing described later, but wear resistance and slidability, for example, the touch panel surface is damaged, and operability is affected.

The modification mentioned here is for providing the conductive silicone rubber layer 2 with a surface treatment layer 2 ′ and an adhesive layer 3 described later, or applying a dye. If this modification is not performed, a desired touch panel operation seal cannot be manufactured. This modification may be performed by a known technique such as a combustion chemical vapor deposition method (see, for example, Japanese Patent Nos. 4058438 and 4033478).

The conductive silicone rubber layer 2 is provided (provided) with a surface treatment layer 2 ′. Surface treatment as used herein refers to slidability and wear resistance when using the touch panel operation seal according to the present invention, peelability and releasability in preventing adhesion between the conductive silicone rubber layer and the touch panel surface. Used to improve. The surface processing layer 2 ', Ru adopted the form of painting a surface treatment for coating charge on the surface of the conductive silicone rubber layer 2. The coating material must maintain the conductivity of the conductive silicone rubber while maintaining the slidability, wear resistance, peelability, and releasability described above. Desirable are fluorocarbon resins, resins based on conductive polythiophene polymers, polyether ether ketone (PEEK) resins, acrylic resins, and the like. Incidentally, in FIG. 2, the surface processed layer 2 ′ has a layer structure for convenience of description, but it is not necessary to stick to the layer structure as long as the properties such as the above-described sliding property can be maintained.

Although the conductive silicone rubber layer 2 is also formed in the above-described embodiment, the conductive silicone rubber layer 2 may be colored using a paint. In this case, a general silicone paint is used as the paint. In addition, about the coloring of conductive silicone rubber, the surface of this conductive silicone rubber should just be painted after conductive silicone rubber molding. As will be described in detail in Examples described later, the coating is performed (surface coating) before the surface processed layer 2 'is formed.

Moreover, additives, such as a deterioration inhibitor, a softening agent, and a flame retardant, can be appropriately added to the conductive silicone rubber layer 2.

Next, the adhesive layer 3 will be described.

The adhesive layer 3 is preferably insulative in order to prevent electric shock to the user. As a material used for the adhesive layer 3, a cyanoacrylate adhesive, an acrylic resin adhesive, a polyvinyl alcohol, a rubber or latex, a silicone adhesive, or the like can be used.
Of these, cyanoacrylate adhesives are preferred. The cyanoacrylate adhesive is used as an instantaneous surgical adhesive. In addition, what is necessary is just to select the above-mentioned adhesive agent suitably, when examining temporary adhesiveness, re-peelability, and complete adhesiveness to the touch finger | toe for touch panel operation, etc. which concern on this invention. The adhesive layer 3 can be used in addition to an adhesive, for example, an insulating double-sided tape, or a combination of the above adhesive and a polymer substrate (for example, polypropylene). In addition, about the adhesive bond layer 3, it can create with a well-known technique.

The thickness of the touch panel operation seal 1 is about 0.3 to 10 mm as a whole. Moreover, if the ratio of the thickness between the conductive silicone rubber layer 2 and the adhesive layer 3 complies with the above-mentioned touch panel operation seal 1 having a thickness of 0.3 to 10 mm, It can be selected as appropriate.

Moreover, when using the touch panel operation sticker according to the present invention, the adhesive layer 3 is attached to the operation finger F (see FIG. 3). Although FIG. 3 shows the case where it is attached to one operating finger F, it can be used by attaching it to the whole one finger or both fingers according to the size of the touch panel and the operation application. The affixing position can also be changed as appropriate.

As shown in FIG. 4, the planar and three-dimensional shape of the touch panel operation seal 1 according to the present invention is an ellipse, a cone, a rectangle such as a rectangle or a square, and a triangle according to a conventional technique such as a punching die. It can be processed into a bowl shape, and a shape matched to the dimensions of the touch panel can be adopted as appropriate.
