(Pen tip for touch pen)
The pen nib for the touch pen of the present embodiment has at least a nib body made of an elastic material and a conductive cloth that covers at least the tip portion of the nib surface of the nib body, A conductive cloth is bonded and fixed.

  In the pen nib for the touch pen according to the present embodiment, the conductive cloth is fixed to the pen nib body by being chemically bonded. Therefore, even if the touch operation is repeated, the fixing portion is loosened due to mechanical fixation. There is no room. For this reason, it is very easy to maintain the state in which the conductive cloth covering the pen tip is stably fixed even if the touch operation is repeated.

  In the pen tip for a touch pen according to the present embodiment, a portion exposed to friction and wear by a touch operation is basically a conductive cloth, not a pen tip body made of an elastic material. Therefore, since the conductive cloth protects the nib body, it becomes easy to suppress wear and cracks of the nib body. Moreover, since the conductivity of the nib is ensured by using a conductive cloth, it is not always necessary to use conductive rubber as an elastic material constituting the nib body. Therefore, when forming the nib body, it is possible to select more diverse materials, more diverse manufacturing methods and conditions, and as a result, it is easier to improve the moldability of the nib body. . Furthermore, the rubber material that constitutes the nib body generally has low slipperiness with respect to the touch panel surface. However, by appropriately selecting the material constituting the conductive cloth, the fiber diameter, the weaving method, etc., it is possible to improve the sliding property and at the same time to ensure the durability against the frictional wear of the pen tip. In particular, when the pen tip is covered with a conductive cloth, the improvement of slipperiness becomes easier. The reason for this is that the contact between the pen tip and the touch panel surface is caused by the unevenness of the fibers constituting the conductive cloth, compared to the case where the pen tip made of conductive rubber and the touch panel surface are in surface contact. It is estimated that this is because the frictional resistance during the touch operation decreases as a result of approaching the contact.

  FIG. 1 is a schematic cross-sectional view showing an example of a pen tip for a touch pen according to the present embodiment. Specifically, a cross section of a cross-section of the touch pen nib 10A (10) taken along a plane including the axial direction C thereof. This is shown in the figure. In the following description, a cross section cut by a plane including the axial direction C of the touch pen nib 10 may be simply abbreviated as “cross section”.

  A pen nib 10A for a touch pen shown in FIG. 1 is a conductive cloth that covers substantially the entire nib surface 22T (22) of the nib body 20A (20) made of an elastic material and the outer surface 22 of the nib body 20A. 30A (30). The pen nib body 20A has a cross-sectional shape whose entire shape is a substantially bullet shape. The outer surface 22 of the nib body 20A includes a bottom surface 22B (22) forming a flat surface on one end side (bottom B side) in the axial direction C, and a surface other than the bottom surface 22B, that is, the side surface portion of the outer surface 22 and the axial direction C. And the pen tip surface 22T (22) forming the surface of the other end side (tip portion T). That is, the pen tip surface 22T is a surface obtained by combining the outer peripheral surface of the cylindrical body and the substantially spherical surface of the hemisphere.

  In addition, a hollow portion 24 that is substantially similar to the cross-sectional shape of the outer surface 22 is provided inside the nib body 20A. A circular opening 26 having an opening diameter D2 smaller than the diameter D1 of the hollow portion 24 is provided at the center of the bottom surface 22B, and the hollow portion 24 communicates with the outside through the opening 26. .

  Here, if the conductive cloth 30A is bonded and fixed to the pen tip surface 22T in at least a part of the interface 40 where the pen tip surface 22T and the conductive cloth 30A are in contact with each other. Good. In this case, for example, (1) the conductive cloth 30 is bonded and fixed to a region (tip region) 22T1 (22, 22T) in the vicinity of the tip portion T of the pen tip surface 22T (first adhesive fixing mode). (2) Adhering and fixing the region 22T2 (22, 22T) on the bottom B side of the side surface portion of the pen tip surface 22T (second adhesive fixing mode) or (3) The pen tip on the entire surface of the interface 40 The conductive cloth 30A can be bonded and fixed to the surface 22T (third bonding and fixing mode).

  In the case of the first adhesive fixing mode, in the touch operation, the conductive cloth 30A is firmly fixed to the pen tip surface 22T in the tip region 22T1 that most frequently contacts the touch panel surface. Therefore, it is possible to reliably prevent the conductive cloth 30A from shifting with respect to the pen tip surface 22T during the touch operation. As a result, a stable touch operation can be realized regardless of the strength of the pressing force applied to the touch panel surface by the touch pen. In the case of the second adhesive fixing mode, since the end of the conductive cloth 30A is firmly fixed to the pen tip surface 22T, the conductive cloth 30A starts from the end of the conductive cloth 30A. It becomes easy to suppress peeling and falling off from the nib surface 22T. Furthermore, in the case of the third adhesive fixing mode, the merits of both the first adhesive fixing mode and the second adhesive fixing mode described above can be obtained. Of the three adhesive fixing modes described above, the first adhesive fixing mode and the third adhesive fixing mode are preferable from the viewpoint that a stable touch operation can be realized. An adhesive fixing mode is more preferable.

  In the example shown in FIG. 1, the conductive cloth 30A is provided so as to cover substantially the entire surface of the pen tip surface 22T, but if it is provided so as to cover at least the tip region 22T1, the pen tip surface 22T. The covering mode of the conductive cloth 30A is not particularly limited. When the conductive cloth 30A is provided so as to cover only the tip region 22T1, the conductive cloth 30A is bonded to the tip region 22T1 by the first adhesive fixing mode.

  Moreover, in the example shown in FIG. 1, although the hollow part 24 is provided in the inside of the nib main body 20A, the hollow part 24 does not need to be provided. In addition, when the hollow part 24 is provided, it can make it easy to attach 10 A of penpoints for touch pens to other members, such as a touch pen main body. Moreover, the touch feeling at the time of pressing the touch panel surface can be adjusted by appropriately selecting the size and shape of the hollow portion 24.

  As shown in FIG. 1, the conductive cloth 30 may be bonded and fixed directly to the nib body 20 </ b> A, or may be bonded and fixed via an adhesive layer. When the conductive cloth 30 is directly bonded to the nib body 20A, the nib body 20A is formed using a rubber material having adhesiveness. Here, as the rubber material having adhesiveness, a rubber material to which an adhesive component is added or a rubber material having self-adhesiveness can be used. As the adhesive component, for example, an epoxy-based adhesion aid can be used, and as the rubber material having self-adhesiveness, for example, a silicone rubber material can be used.

  Here, when the pen tip 10A for the touch pen is manufactured using the rubber raw material having adhesiveness, for example, (1) the rubber raw material having adhesiveness and the conductive cloth 30A are set in the mold and then heated. The surface of a member made of a rubber raw material having an adhesive property that is preliminarily molded into the same shape as the pen nib body 20A in the process of integrally molding by pressure. After affixing the conductive cloth 30 to the pen tip body 20A and the conductive cloth 30 can be bonded by heat treatment. In this case, the heating conditions for adhesion can be appropriately selected according to the composition of the rubber raw material having adhesion, the material constituting the surface of the conductive cloth 30, and the like. Further, the vulcanization treatment of the rubber raw material having adhesiveness and the adhesion treatment may be performed simultaneously or separately.

  On the other hand, when the conductive cloth 30 is bonded and fixed to the nib body 20A via an adhesive layer, an adhesive is applied to one side of the conductive cloth 30 and / or the nib surface 22T of the nib body 20A. Then, the conductive cloth 30 can be adhered and adhered to the pen tip surface 22T. Moreover, in the case of adhesion | attachment, the adhesive tape by which the adhesive agent was apply | coated on both surfaces instead of an adhesive agent can also be used. As the adhesive, a non-conductive adhesive or a conductive adhesive in which carbon particles, silver particles and the like are dispersed and contained in the non-conductive adhesive can be used.

  In addition, the matrix material which comprises the nib main body 20 may be comprised from rubber | gum, and may be comprised from sponge rubber | gum. Furthermore, if necessary, the matrix material may contain a material other than rubber such as a filler in a dispersed manner.

  Moreover, the conductive cloth 30 used for producing the pen point 10 for a touch pen is usually prepared by cutting a large size conductive sheet into a predetermined size. For this reason, burrs are likely to occur at the end of the conductive cloth 30. Moreover, the conductive cloth 30 is easy to peel off starting from the end portion. Therefore, it is preferable that the end of the conductive cloth 30 is sandwiched between the nib body 20 and the covering member from the viewpoint of suppressing the burr from being exposed to the outside and further suppressing the peeling.

  FIG. 2 is a schematic cross-sectional view showing another example of a pen tip for a touch pen according to the present embodiment, specifically, an enlarged cross-sectional view showing an enlarged cross-sectional structure in the vicinity of the end portion of the conductive cloth 30. . In the pen tip 10B (10) for the touch pen shown in FIG. 2, the conductive cloth 30B (30) covers the entire surface of the pen tip surface 22T, and the end portion 30BE of the conductive cloth 30B covers the outer peripheral portion of the bottom surface 22B. Folded to cover. The bottom surface 22B is made of an elastic material including a portion covered with the end portion 30BE of the conductive cloth 30B, and the planar shape is covered with a covering member 50A (50) having the same shape as the bottom surface 22B. Yes. The covering member 50A and the end portion 30BE of the conductive cloth 30B that covers the bottom surface 22B and the outer peripheral portion of the bottom surface 22B are bonded and fixed. Therefore, the end portion 30BE of the conductive cloth 30B is sandwiched between the bottom surface 22B of the nib body 20A and the covering member 50A.

  Here, when producing the pen point 10B (10) for touch pens, for example, it is produced by the following procedure. First, the nib body 20A molded into a predetermined shape is manufactured. Next, the conductive cloth 30B (30) is affixed and adhered so as to cover the entire surface of the pen tip surface 22T, and the end portion 30BE of the conductive cloth 30B is bent to cover the outer peripheral side portion of the bottom surface 22B. Subsequently, a rubber raw material having adhesiveness is filled into a concave portion of a mold having a concave portion whose planar shape is the same as that of the covering member 50A. Then, the nib main body 20A in which the outer peripheral side portion of the bottom surface 22B is covered with the end portion 30BE of the conductive cloth 30B is disposed on the rubber material filled in the recess so that the rubber material and the bottom surface 22B come into contact with each other. To do. Thereafter, the rubber raw material is heat-treated, the rubber raw material is heated and cured to form the covering member 50A, and the covering member 50A and the end portion 30BE of the conductive cloth 30B that covers the bottom surface 22B and the outer peripheral portion of the bottom surface 22B, , Glue. Thereby, the pen point 10B for touch pens is obtained.

  FIG. 3 is a schematic diagram illustrating another example of the pen tip for a touch pen according to the present embodiment. Specifically, the cross-sectional structure in the vicinity of the end of the conductive cloth 30 is enlarged. Here, FIG. 3A shows an enlarged cross-sectional view of a cross section cut along a plane including the axial direction C (not shown in the drawing), similarly to the case shown in FIGS. 1 and 2. is there. FIG. 3B is an end view taken along a line A1-A2 illustrated in FIG.

  The touch pen nib 10C (10) shown in FIG. 3 has substantially the same structure as the touch pen nib 10B shown in FIG. 2, but the end 30CE of the conductive cloth 30C (30) covers the entire surface of the bottom surface 22B. The difference is that the covering member 50B (50) is at least mechanically fixed to the nib body 20B (20) while being covered. Here, the pen nib body 20B is provided with a recess 28 on the bottom surface 22B of the nib body 20A shown in FIGS. 1 and 2, and has the same structure as the nib body 20A except for this point. It is. Further, the conductive cloth 30C (30) is slightly larger in size than the conductive cloth 30B shown in FIG. 2, and a through hole 32 is provided in the vicinity of the end 30CE (30, 30C). Otherwise, it is the same member as the conductive cloth 30B shown in FIG. The covering member 50B (50) is a member having the same size and shape as the covering member 50A shown in FIG. 2 except that the convex portion 52 is provided on one side.

  In the pen tip 10C for the touch pen shown in FIG. 3, the end portion 30CE of the conductive cloth 30C is aligned with the bottom surface 22B so that the through hole 32 of the conductive cloth 30C matches the opening of the recess 28 provided in the bottom surface 22B. Covering the entire surface. The covering member 50B covers the end portion 30CE of the conductive cloth 30C so that the convex portion 52 penetrates through the through hole 32 and fits into the concave portion 28. That is, the end portion 30CE of the conductive cloth 30C is sandwiched between the bottom surface 22B of the nib body 20B and the covering member 50B.

  When the pen tip 10C (10) for a touch pen shown in FIG. 3 is manufactured, for example, it is manufactured by the following procedure. First, the nib main body 20B molded into a predetermined shape is manufactured. Next, the conductive cloth 30C (30) is attached and adhered so as to cover the entire surface of the pen tip surface 22T, and the entire bottom surface 22B is covered by bending the end portion 30CE of the conductive cloth 30C. At this time, the opening of the recess 28 and the opening of the through hole 32 are matched. Subsequently, a rubber raw material having adhesiveness is filled into a concave portion of a mold having a concave portion whose planar shape is the same as that of the covering member 50B. Then, the nib body 20B in which the outer peripheral side portion of the bottom surface 22B is covered with the end portion 30CE of the conductive cloth 30C is disposed on the rubber material filled in the recess so that the rubber material and the bottom surface 22B come into contact with each other. To do. At this time, the rubber raw material is also filled into the recess 28 via the through hole 32. Thereafter, the rubber raw material is heat-treated, and the rubber raw material is heated and cured to form the covering member 50B, and the covering member 50B and the end portion 30BE of the conductive cloth 30B covering the bottom surface 22B are bonded and covered. The convex portion 52 of the member 50B and the concave portion 28 are bonded. As a result, the pen tip 10C for the touch pen is obtained. Further, the pen tip 10C (10) for the touch pen shown in FIG. 3 can be manufactured by the following procedure. First, the convex portion 52 of the covering member 50B that has been molded in advance is inserted into the through hole 32 and the concave portion 28. By fitting the convex portion 52 and the concave portion 28, the pen point 10C for the touch pen can be manufactured. When manufacturing the pen tip 10C for the touch pen in the latter manufacturing process, the covering member 50B may be made of a rubber material, but is made of a material other than the rubber material such as metal, hard plastic, or ceramics. May be.

  Next, the conductive cloth 30 constituting the touch pen nib 10 will be described. As the conductive cloth 30, any known sheet-like material having conductivity as a whole sheet can be used. For example, as the conductive cloth 30, a cloth in which fibers are woven by a known weaving method, a non-woven cloth formed by intertwining fibers without being woven, or a mesh-like cloth having openings in which fibers are woven at a low density, etc. The conductive cloth containing conductive fibers can be used as the fibers constituting the cloth.

  Moreover, as the conductive cloth 30, as exemplified in Patent Document 1, a conductive cloth including conductive particles in which conductive particles are adhered and mixed between the surfaces of the fibers of the cloth and the fibers may be used. it can. However, as the conductive cloth 30, it is particularly preferable to use a conductive cloth including conductive fibers rather than a conductive cloth including conductive particles. This is because in a conductive cloth containing conductive particles, there is a high possibility that the conductive particles fall off from the fibers in the process of repeating the touch operation, and the surface resistance value of the conductive cloth gradually increases. is there. That is, when such an increase in the surface resistance value occurs, the input responsiveness at the time of a touch operation is lowered and the touch panel is likely to malfunction.

  4 and 5 are schematic diagrams illustrating an example of the conductive cloth 30. FIG. Here, the conductive cloth 30D (30) shown in FIG. 4 is a cloth woven so that the warp yarns 34A and the weft yarns 34B are alternately densely entangled, and the conductive cloth 30E (30) shown in FIG. This is a cloth in which warp yarns 34A and weft yarns 34B are woven in a lattice pattern. In the conductive cloth 30E shown in FIG. 5, all the warp yarns 34A and the weft yarns 34B may be integrally formed.

  Here, the fibers constituting the warp 34A and the weft 34 may be fibers composed only of a conductive material such as metal fiber or carbon fiber, and the surface of non-conductive fiber (core material) such as resin fiber or glass fiber. May be a fiber coated with a conductive material such as metal, or may be a fiber whose surface of a conductive fiber (core material) is coated with a conductive material made of a material different from the core material. Moreover, since the electroconductive cloth 30 should just exhibit electroconductivity as a whole, you may mix and use a conductive fiber and a nonelectroconductive fiber as a fiber which comprises the warp 34A and the weft 34B. In this case, as the non-conductive fiber used in combination with the conductive fiber, a known non-conductive fiber can be used. For example, glass fiber, Kevlar fiber, PET (polyethylene terephthalate) fiber, acrylic resin fiber, nylon Resin fibers can be used.

  FIG. 6 is a schematic cross-sectional view showing an example of conductive fibers constituting the conductive cloth 30. The conductive fiber 36 shown in FIG. 6 includes a nonconductive core material 36A and a metal layer 36B that covers the nonconductive core material 36A. Here, the layer structure of the metal layer 36 may be a single layer structure or a multilayer structure of two or more layers. As the non-conductive core material 36A, for example, known non-conductive fibers such as glass fiber, PET fiber, acrylic resin fiber, nylon resin fiber, Kevlar fiber and the like can be used. Further, as a material constituting the metal layer 36B, a known conductive metal such as Cu or Ni or an alloy thereof can be used. In addition, the conductive cloth 30 can select and use a commercial item suitably.

(Touch pens, touch pens with writing instruments, pen tip pens and refills for input pens)
The pen 10 for a touch pen according to the present embodiment can be used as a refill for an input pen such as a portable terminal among the refills of a touch pen, a touch pen with a writing tool, or a pen-tip retractable writing tool.

  Here, the touch pen of the present embodiment includes a rod-shaped main body portion and the pen nib 10 for the touch pen of the present embodiment attached to at least one end of the rod-shaped main body portion. FIG. 7 is a schematic cross-sectional view showing an example of the touch pen of the present embodiment. Specifically, when the touch pen nib 10 </ b> A and the central axis C of the rod-shaped main body 110 shown in the drawing are cut along a plane. It shows about sectional drawing. A touch pen 100 shown in FIG. 7 includes a touch pen nib 10A, a rod-shaped main body 110, a nib attaching member 120, and a cover 130. The touch pen nib 10 </ b> A is attached to one end of the rod-shaped main body 110 via the nib attaching member 120.

  The rod-shaped main body 110 is a columnar member having a diameter that is slightly larger than the diameter of the pen point 10A for the touch pen, and is made of, for example, a conductive material such as metal. A concave portion 112 forming a female screw is provided on one end face of the rod-shaped main body portion 110. Further, the pen tip attaching member 120 includes a cylindrical main body 122 having a diameter approximately equal to the diameter of the touch pen nib 10A, a convex portion 124 for fixing the touch pen nib 10A, and the main body 122. And a convex portion 126 that forms a male screw. Here, the convex portion 124 has substantially the same shape as the opening portion 26 side of the hollow portion 24 and the opening portion 26. And the pen point 10A for touch pens can be fixed to the pen point attachment member 120 by inserting the convex part 124 into the hollow part 24 from the opening part 26. FIG. Further, the pen tip mounting member 120 can be fixed to the rod-shaped main body 110 by inserting the convex portion 126 into the concave portion 112 and screwing it. Also, a cylindrical cover that covers these side surfaces of the pen tip 10 for the touch pen including the end of the conductive cloth 30A and the side surface (outer peripheral surface) of the main body 122 of the pen tip mounting member 120 so as to cover it. 130 is attached. When the touch pen 100 is used, the bar-shaped main body 100 is held by hand, and the touch pen pen tip 10A is pressed against the touch panel surface to perform a touch operation.

  The other end of the rod-shaped main body 110 is provided with a pen tip for writing with a liquid paint such as graphite (solid paint), gel ink (gel paint), oil-based ink or water-based ink. It is good also as a touch pen with. That is, the portion other than the portion to which the pen point 10A for the touch pen of the rod-shaped main body 100 is attached constitutes a normal writing instrument such as a mechanical pencil or a ballpoint pen.

  Moreover, the pen point 10 for touch pens of this embodiment can also be used for the pen tip writing tool provided with one or more rod-shaped refills. In this case, in the input refill of the present embodiment, the tip end portion of the bar-shaped refill is constituted by the pen point 10 for the touch pen. In this case, the operation of the touch panel can be performed on various pen-tip retractable writing instruments simply by replacing other rod-shaped refills with the input pen refill of the present embodiment. In addition, the pen tip retractable writing instrument of the present embodiment using the input pen refill of the present embodiment only needs to include one or more bar-shaped refills, but usually includes two or more bar-shaped refills. Preferably it is. Further, when the pen tip retractable writing instrument of the present embodiment includes two or more bar-shaped refills, one bar-shaped refill is composed of the input pen refill of the present embodiment, and the remaining bar-shaped refills are ballpoint pen refills, etc. It is preferable that it is a normal refill for writing.

  From the viewpoint of more reliably generating a change in capacitance during operation of the touch panel by further increasing the electrical conduction from the tip of the pen tip 10 for the touch pen to the hand holding the pen tip retractable writing instrument, It is preferable to use a conductive member such as a metal member or a member coated with a metal film as a member of each part constituting the input pen refill and the pen tip retractable writing instrument. However, these conductive members may be disposed at a minimum at a position where a conduction path from the tip of the pen tip 10 for the touch pen to the hand holding the pen tip writing tool can be formed.
