Description

  The present invention relates to an artificial nail that can accurately operate a device including a capacitive touch panel such as a mobile phone terminal or a tablet PC without using an operation member such as a touch pen.

  In recent years, devices equipped with a touch panel, such as mobile phone terminals (including smartphones), PDAs (personal digital assistants), tablet PCs, and portable game devices, are widely used. Among them, a capacitive touch panel (in particular, a projection-type capacitive touch panel) (hereinafter also simply referred to as “touch panel”) has high durability against dust and water, has a high response speed, and has a high resolution. Since it has advantages and multipoint detection is possible, it is widely used in smartphones and the like. The touch panel is superior in that it can be operated more directly (intuitively) than the case where the user performs key input.

  In the capacitive touch panel, an electric field is formed on the panel surface, and the touch position is determined by detecting a change in the capacitance on the panel surface. In order to correctly determine the touch position, it is necessary that the panel surface and the contact object (finger, touch pen, etc.) are in contact with each other over a predetermined area. Usually, the user operates his / her touch panel by bringing his / her finger or touch pen having conductivity into contact with the panel surface over a predetermined area.

  An example of a touch pen with improved visibility during operation is disclosed in Patent Document 1. The touch pen described in Patent Document 1 includes a plate-like body made of a transparent conductive resin at the pen tip, and the user can operate the touch panel while checking the screen.

  By the way, artificial nails are widely known as a type of nail art. An artificial nail refers to an artificial nail that is pasted or kneaded on a self-nail (hereinafter also simply referred to as a “nail”). The artificial nail can be used for the purpose of concealing nail defects and discoloration, as well as imparting aesthetics to the nail.

  The artificial nail is generally made of an insulating plastic material (for example, acrylic resin). Therefore, when the user wearing the artificial nail tries to operate the touch panel by bringing the artificial nail into contact with the panel surface, there is a problem that the touch position is not correctly determined. Further, if the user tries to operate the panel surface while wearing the artificial nail, it is difficult to accurately operate the touch panel other than using the belly or the side of the finger. In addition, it is conceivable that a user wearing an artificial nail operates the touch panel using the touch pen described above, but an operation member such as a touch pen needs to be provided at all times, which does not lead to a fundamental solution. Further, the touch pen cannot perform multi-touch, and the function of the capacitive touch panel is greatly limited.

JP 2011-242903 A

  The present invention has been made in view of the above-described conventional problems, and provides an artificial nail that can accurately operate a device including a capacitive touch panel without using an operation member such as a touch pen. For the purpose.

  An artificial nail according to one aspect of the present invention is an artificial nail for operating a device provided with a capacitive touch panel, and is formed of a conductive material, and includes a nail body portion having a decoration surface, and the decoration It is provided on the back surface of the surface, and has an adhesion surface for adhering to the nail, and an operation surface provided integrally with the nail body and operating the capacitive touch panel.

  The artificial nail of the present invention can be bonded to the nail through the bonding surface. The artificial nail of the present invention has a nail body portion made of a conductive material, and the nail body portion is provided with an operation surface. Therefore, the user wearing the artificial nail of the present invention makes the operation surface of the nail body part contact the panel surface of the device equipped with the capacitive touch panel without using the belly or the side part of the finger. Thus, the capacitance of the panel surface can be changed. Since the user can directly operate the touch panel, the user can accurately operate the touch panel without using an operation member such as a touch pen.

  The said structure WHEREIN: It is preferable that the said nail | claw main-body part contains the front-end | tip part provided in the edge part of the said to-be-decorated surface, and the said operation surface is provided in at least any one of the said front-end | tip part or the to-be-decorated surface. .

  In the above configuration, when the operation surface is provided at the distal end portion, the user can contact the operation surface with the touch panel in the same manner as when the tip of the finger is brought into contact with the panel surface, and can operate the touch panel more naturally (described later). See FIG. 3). When providing an operation surface on the surface to be decorated, the user can operate the touch panel by bending a finger and bringing the operation surface into contact with the panel surface (see FIG. 8 described later).

  Furthermore, when providing an operation surface on both the tip portion and the surface to be decorated, the user can operate the touch panel in any method. At this time, if the area of the operation surface provided at the tip portion is different from the area of the operation surface provided on the decoration surface, for example, one of them is relatively narrow so that it can be used when a fine operation is required. It is possible to properly use the area.

  The said structure WHEREIN: It is preferable to provide the convex part protrudingly provided by at least any one of the said front-end | tip part or the said to-be-decorated surface, and this convex part has the said operation surface on the upper surface.

  By using the upper surface of the convex portion protruding from at least one of the tip or the surface to be decorated as the operation surface, the user touches the operation surface with the touch panel in the same way as when the tip of the finger is brought into contact with the panel surface. The touch panel can be operated more naturally (see FIG. 3 described later). Further, the user can operate the touch panel by bending a finger and bringing the operation surface into contact with the panel surface (see FIG. 8 described later). Since the operation surface is provided on the upper surface of the convex portion, it is easy to specify the operation position during operation, and the user can operate the touch panel more accurately.

In the above configuration, the claw body portion preferably includes an insulating base and a conductive layer laminated on the base.

  By providing the artificial nail of the present invention with the above-described configuration, it is not necessary to form the base portion with a conductive material. For this reason, the artificial nail of the present invention can adopt various materials including insulating materials such as conventional plastic materials and wood as raw materials, can widen the range of material selection, and further improve functionality, aesthetics, etc. Can be made.

  The said structure WHEREIN: It is preferable that the said front-end | tip part is at least partially formed with an elastic member.

  In this case, the user can elastically deform the tip portion by pressing the tip portion against the panel surface. Since the elastically deformed tip portion is in surface contact with the panel surface, it can function as an operation surface. Therefore, since the tip of the artificial nail of the present invention can have another shape (for example, a curved shape) except during operation, the aesthetic appearance can be further improved.

  ADVANTAGE OF THE INVENTION This invention can provide the artificial nail which can operate correctly the apparatus provided with the electrostatic capacitance type touch panel, without using operation members, such as a touch pen.

(Embodiment 1)
An artificial nail according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic perspective view illustrating the configuration of the artificial nail 1 of the present embodiment (Embodiment 1). FIG. 2 is a schematic diagram of a state in which the artificial nail 1 is mounted on the user's nail N (nail plate), and FIG. 2 (a) is a side view of the state in which the artificial nail 1 is mounted on the user's nail N. FIG. 2B is an end view, and FIG. 2B is a plan view of the artificial nail 1 attached to the user's nail N. FIG.

  As shown in FIG. 1, the artificial nail 1 has a nail body 2, an adhesive surface 3 bonded to a user's nail N, and an operation surface 4 for operating the touch panel. As shown in FIGS. 2A and 2B, the artificial nail 1 is used by being attached to a user's nail N. The user can operate the touch panel of the smartphone (equipment having a capacitive touch panel) while wearing the artificial nail 1 (see FIG. 3 described later).

(Nail body 2)
The nail body 2 includes a surface to be decorated 5 that covers the nail plate of the nail N, a tip 6 that is provided on the toe side end of the surface 5 to be decorated, and a rear end 7 that is located on the base side of the nail plate. And a side edge portion 8 located on the side edge side of the nail plate. The nail body 2 is made of polyacrylic resin (synthetic resin) containing carbon black (conductive material) in a dispersed state. The back surface of the artificial nail 1 has a curved shape similar to that of the nail plate so that the artificial nail 1 adheres to the user's nail N (nail plate) via an adhesive surface 3 described later.

  The method of molding the nail body 2 is not particularly limited, and a polyacrylic resin may be injection-molded using a mold, and a molten or gel (gel) polyacrylic resin is applied to the user's nail N. The coating may be spread, and light irradiation (ultraviolet irradiation) or heat curing may be performed as necessary.

  The decorated surface 5 is a surface corresponding to the nail plate of the artificial nail 1. The decoration surface 5 can be decorated with various colors, patterns, decorations, and the like. The to-be-decorated surface 5 and the front-end | tip part 6 are comprised with the same material, and there is no clear boundary. Therefore, in the present embodiment, when the user's nail N and the artificial nail 1 are bonded via the bonding surface 3 to be described later, as shown in FIG. This portion is referred to as the tip portion 6 for convenience. The definition of the front end portion 6 is not limited to this, and for example, a predetermined length from the end portion of the artificial nail 1 may be defined uniformly with the front end portion 6.

  The distal end portion 6 has a shape (non-linear taper shape) curved downward toward the distal end of the artificial nail 1. The artificial nail 1 has an operation surface 4 to be described later on a part of the curved tip portion 6.

  In addition, the shape of the front-end | tip part 6 is not specifically limited, For example, the shape bent downward toward the front-end | tip of the artificial nail 1 other than the curved shape as shown to Fig.2 (a) (linear taper shape) It may be a linear shape in which a surface to be decorated is attached and extended toward the tip of the nail 1 without bending or bending.

(Adhesive surface 3)
The bonding surface 3 is a surface provided on the back surface of the nail body 2. The artificial nail 1 is bonded to the user's nail N through the bonding surface 3. A double-sided adhesive tape (not shown) is affixed to the adhesive surface 3. Specifically, a double-sided adhesive tape provided with release paper on both sides is attached to the back surface of the nail body 2 in a state where only the release paper on one side is peeled off. The user can attach the artificial nail 1 to the nail N by bringing the adhesive surface 3 and the nail plate into close contact with each other by peeling off the other release paper of the double-sided tape attached to the adhesive surface 3.

  The method for imparting adhesiveness to the nail N on the bonding surface 3 is not particularly limited, and other than using a double-sided adhesive tape, for example, an adhesive may be applied to the back surface of the nail body 2 to bond the bonding surface. 3 may be provided with adhesiveness. It does not specifically limit as an adhesive agent, A cyanoacrylate type instantaneous adhesive agent, the other well-known adhesive for artificial nails, an adhesive, etc. can be used.

  The adhesion position of the artificial nail 1 to the nail N is not particularly limited. In the present embodiment, as shown in FIGS. 2A and 2B, the artificial nail 1 has the rear end 7 and the side edge 8 of the artificial nail 1 in contact with the skin around the nail N. Glued in place. By bonding in this way, when the user wearing the artificial nail 1 operates the touch panel P (see FIG. 3), a capacitor (capacitance) is provided between the touch panel P and the user wearing the artificial nail 1. Can be formed. In this case, if the operation surface 4 described later is brought into contact with the panel surface Pa (see FIG. 3), the capacitance of the panel surface Pa can be changed, and the user can operate the touch panel P. In the “contact” in the present embodiment, in addition to the state in which the operation surface 4 is physically in contact with the panel surface Pa, the contact position is determined even if the operation surface 4 and the panel surface Pa are not in contact. Includes detected condition. This is because, when the detection sensitivity of the touch panel P is excellent, the contact target object having conductivity such as the artificial nail 1 may be detected just by approaching the touch panel P. Because.

(Operation surface 4)
The operation surface 4 is a surface for operating the touch panel P, and is provided on a part of the nail body 2 made of polyacrylic resin containing carbon black in a dispersed state. The operation surface 4 is provided on a flat surface formed at a part of the distal end portion 6. The user can change the capacitance of the panel surface Pa by bringing the operation surface 4 into contact with the panel surface Pa, and can operate the touch panel P.

The operation surface 4 is a flat surface having a contact area that allows the touch panel P to determine the contact of the artificial nail 1 when contacting the panel surface Pa. The minimum contact area required when operating the touch panel P is not particularly limited because it depends on the performance of the touch panel P or the like, but is preferably set to a contact area (about 7 mm ² ) or more corresponding to a circle having a diameter of about 3 mm, for example. On the other hand, the maximum contact area is not particularly limited, but is preferably, for example, 200 mm ² or less so that the user can accurately perform fine operations and does not impair the aesthetic appearance of the artificial nail 1. When the contact area when the operation surface 4 is in contact with the panel surface Pa is within the above range, the contact area between the artificial nail 1 and the panel surface Pa is sufficiently secured. The touch panel P can be operated more accurately.

  FIG. 3 is a schematic diagram illustrating a state in which the user operates the touch panel P of the smartphone. The user presses the tip of the finger F with the artificial nail 1 attached to the finger F in the same manner as when the tip of the finger F (for example, the belly portion of the finger) is brought into contact with the panel surface Pa when the artificial nail 1 is not attached. By moving to A1, the operation surface 4 can be brought into contact with the touch panel P to operate the touch panel P. In FIG. 3, the artificial nail 1 is attached to each nail of the user.

  As described above, according to the artificial nail 1 of the present embodiment, the user can bond the nail N and the artificial nail 1 via the bonding surface 3. Since the artificial nail 1 has a nail body 2 made of polyacrylic resin containing carbon black in a dispersed state, a user wearing the artificial nail 1 makes the panel surface Pa by bringing the artificial nail 1 into contact with the panel surface Pa. Can be changed. Further, since the artificial nail 1 has the operation surface 4 for operating the touch panel P, the user can directly operate the touch panel P without using the belly or the side of the finger, such as a touch pen or the like. The operation member is not required. Further, if the user attaches the artificial nail 1 to a plurality of fingers F (for example, the index finger and the middle finger), the user can operate the touch panel P by multi-touch.

(Embodiment 2)
FIG. 4 is a schematic perspective view for explaining the configuration of the artificial nail 1a of the present embodiment (Embodiment 2). FIG. 5 is a schematic diagram of a state in which the artificial nail 1a is mounted on the user's nail N, and FIG. 5 (a) is a side end view of the state in which the artificial nail 1a is mounted on the user's nail N. FIG. 5B is a plan view showing a state in which the artificial nail 1a is attached to the user's nail N. FIG.

  As shown in FIGS. 4 and 5A, the artificial nail 1a has an operation surface 4a formed as a plane substantially orthogonal to the surface to be decorated 5 at the tip 6a of the nail body 2a. The configuration is the same as that of the artificial nail 1 of the first embodiment. Therefore, the same reference numerals are assigned to the same components other than the differences, and the description is omitted.

  As shown in FIG. 4 and FIG. 5A, a projecting piece 9 extending in a substantially vertical direction is formed at the tip 6a of the artificial nail 1a. The operation surface 4a is a substantially vertical surface formed on the protruding piece 9, and the user can change the capacitance of the panel surface Pa by bringing the operation surface 4a into contact with the panel surface Pa. (See FIG. 3). The length of the protruding piece 9 in the thickness direction of the artificial nail 1a is not particularly limited, and can be, for example, about 3 to 10 mm.

  According to the artificial nail 1a, as shown in FIG. 4 and FIG. 5 (b), the operation surface 4a has a width (about 10 to 20 mm) substantially equal to the lateral width of the artificial nail 1a. Further, as described above, the length of the protruding piece 9 in the thickness direction of the artificial nail 1a is about 3 to 10 mm. Therefore, the user can easily make the operation surface 4a of the artificial nail 1a face the panel surface Pa and make contact with a sufficient contact area, so that the touch position can be easily determined correctly.

(Embodiment 3)
FIG. 6 is a schematic perspective view for explaining the configuration of the artificial nail 1b of the present embodiment (Embodiment 3). FIG. 7 is a schematic diagram of a state in which the artificial nail 1b is mounted on the user's nail N, and FIG. 7 (a) is a side end view of the state in which the artificial nail 1b is mounted on the user's nail N. FIG. 7B is a plan view showing a state in which the artificial nail 1b is mounted on the user's nail N. FIG.

  As shown in FIGS. 6, 7 (a) and 7 (b), the artificial nail 1 b has an operation surface other than the tip 6 b of the artificial nail 1 b as well as the decorative surface 5. Has the same configuration as the artificial nail 1 of the first embodiment. Therefore, the same reference numerals are assigned to the same components other than the differences, and the description is omitted. 6, 7 </ b> A, and 7 </ b> B, reference numeral 4 c indicates an operation surface formed on the tip portion 6 b, and reference numeral 4 d indicates an operation surface formed on the decoration surface 5. Shows the surface.

As shown in FIGS. 6, 7 (a), and 7 (b), the decorative surface 5 of the artificial nail 1 b has a convex portion 10 (tip) that exhibits a star shape in a top view of a substantially flat shape. And a projecting portion projecting from at least one of the surface and the surface to be decorated. Similar to the claw body portion 2b, the convex portion 10 is made of a polyacrylic resin containing carbon black in a dispersed state and has conductivity. The upper surface of the convex portion 10 is planar and can function as the operation surface 4d. The area of the upper surface is preferably equal to or larger than the contact area (about 7 mm ² ) corresponding to, for example, a circle having a diameter of 3 mm, similarly to the contact area of the operation surface 4d described above.

  The planar shape, the number, and the arrangement position of the convex portions 10 can be appropriately selected according to the user's aesthetics, and are not particularly limited. The planar shape of the convex portion 10 is only required to be a plane having a predetermined area or more on the upper surface. For example, a circular shape (including an ellipse), a square shape, a character shape, a symbol shape, a flora and fauna motif, and other indefinite matters It may be a shape or the like. Moreover, the number of the convex parts 10 should just be one or more, and is not specifically limited. For example, the convex portion 10 may be a convex portion group provided with a plurality of convex portions having large and small similar shapes when viewed from above, or a convex portion group provided with a plurality of large and small convex portions each having a different shape. Also good. In this case, when the height of the plurality of protrusions (the length in the thickness direction of the nail N) is the same, the plurality of protrusions and the panel surface Pa (see FIG. 8) are in contact with each other at the same time. There is a possibility that the touch position of the touch panel P (see FIG. 8) is not correctly recognized. Therefore, it is preferable that the height of the convex portion is adjusted as appropriate so as not to cause such erroneous recognition. Furthermore, the arrangement position of the convex part 10 should just be at least any one on the to-be-decorated surface 5 or the front-end | tip part 6b, and is not specifically limited. For example, the arrangement position of the convex portion 10 may be near the center of the surface 5 to be decorated, near the rear end portion 7a (the base of the artificial nail 1b), or on the front end portion 6b. Good.

  In addition, the method of protrudingly providing the convex part 10 integrally with the to-be-decorated surface 5 of the nail | claw main-body part 2b is not specifically limited. The convex portion 10 may be molded integrally with the nail body portion 2b by injection molding or the like, and the decorative surface 5 of the nail body portion 2b molded separately and the back surface of the convex portion 10 are bonded with an adhesive or the like. May be.

  FIG. 8 is a schematic diagram for explaining a state in which a user who wears the artificial nail 1b on the nail N operates the touch panel P. In addition to the mode described with reference to FIG. 3, the user wearing the artificial nail 1 b can use the operation surface 4 d formed on the upper surface of the convex portion 10 with the finger F folded as shown in FIG. 8. The touch panel P can be operated in contact with the panel surface Pa by moving in the pressing direction A2. In FIG. 8, the artificial nail 1b is attached to each nail of the user.

  Here, for example, when the adhesion between the nail N (nail plate) and the nail body 2b is weakened due to long-term wearing or the like, if the user operates the touch panel P in the manner shown in FIG. Since the stress applied from the panel surface Pa to the artificial nail 1b is continuously applied in a direction substantially parallel to the adhesive surface 3, the artificial nail 1b may be peeled off from the nail N (nail plate). However, when the user operates the touch panel P in the manner shown in FIG. 8, the impact at the time of operation continues to be applied in a direction substantially orthogonal to the adhesive surface 3, so that the artificial nail 1 b becomes nail N ( The possibility of peeling from the nail plate) may be reduced. Moreover, when providing the operation surface (operation surface 4c and operation surface 4d) in both the front-end | tip part 6b and the to-be-decorated surface 5, the user can operate the touch panel P in any method. At this time, if the area of the operation surface 4c provided at the distal end portion 6b is different from the area of the operation surface 4d provided on the surface to be decorated 5, the user can, for example, finely operate one of the operation surfaces. For example, it is possible to selectively use a relatively small area so that it can be used.

  As mentioned above, according to the artificial nail 1b of this embodiment, the convex part 10 provided in the to-be-decorated surface 5 can provide an aesthetics to the artificial nail 1b as a decoration. Further, the user can operate the touch panel P by at least two modes (the modes illustrated in FIG. 3 or FIG. 8). In particular, the convex surface 10 is provided on the surface to be decorated 5 and the upper surface of the convex portion 10 is used as the operation surface 4d, so that the user operates the touch panel P in a manner in which an impact on the artificial nail 1b is not easily applied during operation. be able to.

  As shown in FIGS. 9 and 10 (a), the artificial nail 1c is formed with a convex group 11 including an operation surface 4e on the surface to be decorated 5 of the nail body 2c, as shown in FIG. 10 (b). As described above, the artificial nail 1c has the same configuration as the artificial nail 1b of the third embodiment except that the rear end portion 7b of the artificial nail 1c is not in contact with the skin of the nail N. Therefore, the same reference numerals are assigned to the same components other than the differences, and the description is omitted.

  As shown in FIGS. 9 and 10 (b), the surface 5 of the artificial nail 1 c is integrally provided with five substantially flat convex portions that are different in size and constitute a convex group 11. ing. Each convex portion is circular in top view. Each convex part is made of polyacrylic resin containing carbon black in a dispersed state, and has conductivity.

  The method for providing the convex group 11 on the surface to be decorated 5 is not particularly limited. The convex portion group 11 may be integrally molded with the nail body portion 2c by injection molding or the like, and the decoration surface 5 of the nail main body portion 2c and the back surface of the convex portion group 11 which are separately molded are bonded with an adhesive or the like. It may be glued. For example, the convex portion group 11 can be bonded to the decorated surface 5 by using the back surface of at least one convex portion constituting the convex portion group 11 as an adhesive surface.

  The convex portion 10a has the largest upper surface area among the five convex portions, and can function as the operation surface 4e. Moreover, the convex part 10b has the extension part 10b1 which one part extended from the to-be-decorated surface 5, and the said extension part 10b1 is a side part of a user's nail | Nail N in the state which mounted | wore with the artificial nail 1c. May come into contact with the skin. Each convex part which comprises the convex part group 11 is in contact with the adjacent convex part. For this reason, the user wearing the artificial nail 1c operates the touch panel P in the manner described with reference to FIG. 8, for example, so that a capacitor (capacitance) is provided between the touch panel P and the user wearing the artificial nail 1c. ) And the touch panel P can be operated.

  As shown in FIGS. 10A and 10B, the artificial nail 1c has a rear end portion 7b of the artificial nail 1c that is not in contact with the skin of the nail N. Therefore, the size (length) of the artificial nail 1c can be reduced. Further, since the artificial nail 1c is bonded so as to overlap with the nail N, an excellent aesthetic appearance can be imparted.

(Embodiment 5)
FIG. 11 is a schematic perspective view illustrating the configuration of the artificial nail 1d of the present embodiment (Embodiment 5). FIG. 12 is a schematic diagram of a state in which the artificial nail 1d is attached to the user's nail N, and FIG. 12 (a) is a side end view of the state in which the artificial nail 1d is attached to the user's nail N. FIG. 12B is a plan view showing a state in which the artificial nail 1d is attached to the user's nail N. FIG.

  As shown in FIGS. 11 and 12 (a), the artificial nail 1d has a claw body 2d laminated with a wooden base 12 (insulating base) and carbon black in a dispersed state. Except for including the polyacrylic resin layer (conductive layer) to be included, it has the same configuration as the artificial nail 1b of the third embodiment. Therefore, the same reference numerals are assigned to the same components other than the differences, and the description is omitted.

  As shown in FIG. 12A, the artificial nail 1 d includes a base portion 12 and a polyacrylic resin layer 13 in which the base portion 12 is laminated on the base portion 12. The base 12 is made of wood and has an insulating property. A polyacrylic resin layer 13 is laminated so as to cover the base 12.

  The method for laminating the polyacrylic resin layer 13 on the base 12 is not particularly limited. For example, it may be produced by spreading a melted polyacrylic resin on a shaped wooden base 12, and a separately prepared polyacrylic resin layer 13 is applied to the base 12 with the above-mentioned known adhesive. The adhesive surface 3 may be formed on the back surface of the base portion 12, and the melted polyacrylic resin may be bonded to the surface of the base portion 12 while being bonded to the user's nail N (nail plate) via the adhesive surface 3. It may be spread over. The polyacrylic resin in the molten state can be cured by a method such as light (UV, ultraviolet) irradiation or thermosetting according to the properties of the conductive material contained.

  The thickness of the polyacrylic resin layer 13 is not particularly limited. For example, the thickness of the polyacrylic resin layer 13 can be several nm to several mm. When the user operates the touch panel P by using the upper surface of the convex portion 10 formed on the decorated surface 5 as the operation surface 4f as described with reference to FIG. 8, the polyacrylic resin layer 13 If the thickness of the protrusion 10 is too large, the height of the protrusion 10 relative to the surface to be decorated 5 may become too small as a result of the protrusion 10 being buried in the polyacrylic resin layer 13. In this case, when the upper surface of the convex part 10 is brought into contact with the panel surface Pa, the surface to be decorated 5 is also brought into contact with the panel surface Pa, and the touch panel P may not be operated accurately. Therefore, it is preferable to increase the height of the convex portion 10 according to the thickness of the polyacrylic resin layer 13 or reduce the thickness of the polyacrylic resin layer 13 according to the height of the convex portion 10.

  The user wearing the artificial nail 1d can operate the touch panel P by bringing any part where the polyacrylic resin layer 13 is laminated into contact with the panel surface Pa. For example, as described with reference to FIG. 3, the user uses the plane formed on the distal end portion 6 as the operation surface 4 g and operates the touch panel P by bringing the panel surface Pa and the operation surface 4 g into contact with each other. As described with reference to FIG. 8, the upper surface of the convex portion 10 formed on the decoration surface 5 is used as the operation surface 4f, and the touch panel P is operated by bringing the panel surface Pa and the operation surface 4f into contact with each other. obtain.

  Since the artificial nail 1d has the polyacrylic resin layer 13, the base 12 constituting most of the nail body 2d does not need to contain carbon black. Therefore, the artificial nail 1d can employ various materials including an insulating material such as a conventional plastic material and wood as a raw material, can widen the range of material selection, and further improve the functionality and aesthetics. Can do.

FIG. 13 is a schematic side end view of a state in which the artificial nail 1e of the present embodiment (Embodiment 6) is attached to the user's nail N. FIG. FIG. 14 is a schematic diagram of a state in which the user wearing the artificial nail 1e is operating by touching the artificial nail 1e on the touch panel P (see FIG. 3). FIG. 14 (a) shows the artificial nail 1e being attached. FIG. 14B is a side end view of a state in which the user who has touched the touch panel P touches the artificial nail 1e, and FIG. 14B shows a case where the user wearing the artificial nail 1e contacts the touch nail 1e. It is a top view of the state which is operating.

  The artificial nail 1e is the same as the artificial nail 1 of the first embodiment except that the nail body 2e (including the tip 6c) is made of conductive silicone (elastic member) containing carbon black in a dispersed state. It has the composition of. Therefore, the same reference numerals are assigned to the same components other than the differences, and the description is omitted.

  As shown in FIG. 13, the artificial nail 1 e has a curved tip shape 6 c and is not a flat surface. However, since the nail body 2e is made of conductive silicone and the tip 6c has elasticity, the user operates the touch panel P as shown in FIGS. 14 (a) and 14 (b). For this purpose, when the tip 6c of the artificial nail 1e is brought into contact with the panel surface Pa, a part of the tip 6c can be elastically deformed. The elastically deformed tip portion 6c is formed with a plane having an area that can sufficiently function as the operation surface 4h. Therefore, the artificial nail 1e can have the tip 6c in other various shapes (for example, a curved shape, etc.) except during operation, so that the appearance of the artificial nail 1e can be further improved.
