Description

  The present invention relates to a touch pen for a capacitive input pad for inputting coordinate information to a capacitive input pad connected to an information processing apparatus such as a personal computer or a portable terminal.

Conventionally, when inputting information to a capacitive coordinate input device or a display-integrated capacitive input device of a computer, the information is input directly with a finger.
However, the finger is disadvantageous in that the contact state with the input panel changes due to force adjustment and the position is shifted, and the operability is inferior when the finger slips due to sweat or the like. Various proposals have already been made for such drawbacks. These are mainly composed of a conductive pen tip and a conductive shaft, and are proposals for enabling stable writing and position detection while ensuring conduction from the input panel to the finger.

  First, a pen tip made of a water-absorbing material and a water retaining portion provided inside the shaft body are impregnated with water, and further, a connection from the input panel to the finger is ensured through the conductive shaft body (Patent Literature). 1). In this case, since the handwriting of water remains on the panel, accurate position information may not be input due to the influence of water on the panel surface when used continuously. In addition, it could cause a fatal accident, such as attaching water to an electronic device that is extremely precise.

  Next, using a conductive fiber brush or conductive felt at the tip of the pen, further ensuring conduction from the input panel to the finger through the conductive shaft, the input pen electrostatically flocked with conductive fibers, It has been proposed by the present applicant (Patent Document 2). In this case, the tip of the brush or felt was relatively soft, the feel during input was soft, and the input panel was not damaged. The conductive fibers listed here are: “Acrylic fibers, nylon fibers, glass fibers, etc., conductive fibers adsorbed with copper ions, etc., metal-plated fibers, etc. It may be a fiber or a fiber in which a metal is deposited in the pores, and it may be any fiber as long as it is conductive and has a certain degree of flexibility. However, these fibers are electrostatically flocked only at the dome-shaped portion at the tip, and there is a drawback that deformation such as the spread of the fibers is remarkable and the contact area unintentionally spreads. In addition, since the area where the hair is planted is small, the force concentrates on the planted area, and the fibers are easily damaged and dissipated. This broken fiber can easily create fine scratches on the input panel surface. There was a drawback that unintended input was made on the panel. Further, these input pens have to be secured from the pen tip to the user's hand, and are limited in design such as selection of materials. In addition, when the planted fiber has fallen off, the pen tip cannot be attached / detached / replaced, which is a so-called disposable one.

  In addition, as a means for ensuring conduction from the input panel to the finger, the present applicant has proposed that a conductive rubber is used for the pen tip and a conductive shaft is passed through (Patent Document 3). In this case, there was no problem in the pointing operation, and the feel during input was soft and did not damage the input panel. However, the sliding of the rubber was bad, and the sliding operation was highly resistant and comfortable to slide. could not.

  Furthermore, conductive carbon fibers and resin fibers are blended into the nib, and a fiber bundle is used that is bonded by thermal welding of resin binder and resin fibers. The applicant has also proposed to secure the above (Patent Document 4). In this case, a nib with moderate sliding is obtained, and suitable operation is possible in both pointing and sliding operations, but the conductivity may be hindered because the resin binder covers the outside of the conductive fibers. In addition, since the carbon fiber is hard, the panel surface is damaged, and conversely, the carbon fiber is damaged and falls off and dissipates.

JP-A-8-44484 (Examples) Japanese Patent Laid-Open No. 10-39989 (claims, [0008], [0020], etc.) Japanese Patent Laid-Open No. 10-161895 (claims, etc.) Japanese Patent Laid-Open No. 10-161796 (claims, etc.)

  The object of the present invention is to eliminate the above-mentioned drawbacks, that is, without causing a conductive liquid such as water to adhere to the input device, with little displacement of the detection position due to writing pressure, good sliding during the sliding operation, and a soft touch And providing a touch pen for a capacitance-type input pad having an input tip that does not damage the panel surface.

In the following description, the front end side of the input touch pen in the axial direction is the front side, and the opposite side is the rear side.
As a material used for the base material of the input tip in the present invention, any solid material such as wood, stone, ceramics, metal, or resin can be used without limitation. Since the input tip is preferably conductive, the material used for the base material is preferably a metal, a conductive resin, a ceramic or a resin that includes a conductive substance and has conductivity. However, even a material that does not normally have conductivity, such as wood or stone, may be used with conductivity by applying a conductive material to the surface thereof. Of the above materials, it is more preferable to use a resin from the viewpoints of flexibility, moldability, easily modifiable properties, and the like. Examples of resins include thermosetting resins such as silicone resins, urethane resins, fluorine resins, and vulcanized rubber, or styrene resins, vinyl chloride resins, olefin resins, urethane resins, polyester resins, and nitriles. And thermoplastic resins such as thermoplastic resins, polyamide resins, silicone resins of thermoplastic resins, and fluororesins of thermoplastic resins.

  In the present invention, the input pointed base material has a low probability of the base material surface coming into contact with the input panel and can be used without worrying about its hardness because a flexible convex portion described later is adhered to the surface. . However, as the use of the touch pen of the present invention is continued, the bonded convex portion is dropped, and an opportunity for the input tip base material to directly contact the input panel is generated. At this time, if a material having a high rigidity (shear elastic modulus) is used, the input panel is damaged. For this reason, it is preferable to use a resin for the input pointed base material.

If the above-mentioned resin is used as a base material, it exhibits a certain degree of elasticity, so that a certain degree of flexible input feeling is given and the possibility of damaging the input panel is low. The preferable rigidity of these resins is 1 × 10 ⁻⁴ to 1 × 10 ⁹ N / m ² , more preferably 1 × 10 ⁻⁴ to 1 × 10 ⁸ N / m ² , and still more preferably 1 × 10 ⁻⁴ to 1 × 10 ⁷ N / m ²

  When a resin is used for the base material of the input tip, it is possible to easily mix or combine conductive materials. Examples of the material of the conductive material that can be used include a resin solution in which a conductive resin such as polypyrrole, polythiophene, polyethylenedioxythiophene, polyisothianaphthene, and polyaniline is dispersed or solubilized. When using these conductive materials, 2,3,7,8-tetracyano-1,4,6,9-tetraazanaphthalene, dodecylbenzenesulfonic acid, p-toluenesulfone are used in order to appropriately adjust the conductivity. A conductive resin to which a dopant such as an acid is added can be used.

  As this conductive material, a general resin solution in which carbon black, graphite, metal particles and the like are dispersed or a molten resin may be used. In this case, there is a possibility that the rubber hardness of the base material at the input tip changes due to mixing of carbon black, graphite, metal particles, etc., so it is necessary to adjust the rubber hardness to an appropriate one.

In the present invention, the resin used for the spherical or massive convex portion on the surface of the input tip is the same thermosetting resin as the base material of the input tip, or a thermoplastic resin such as a silicone resin or a fluorine resin. Can be mentioned. Since these resins exhibit a certain degree of elasticity, the possibility of damaging the input panel is low as with the base material of the input tip. In addition, even if the rigidity is set extremely hard for fine adjustment of the input feeling of the user, if the rigidity of the base material of the input tip is low, when the touch pen is pressed against the input panel, this Spherical or massive protrusions are pushed into the interior of the substrate, reducing the possibility of damaging the input panel. In any case, the rigidity of the spherical or massive convex portion must be set in relation to the properties of the base material of the input tip. In the case where a material having a high rigidity of 1 × 10 ⁷ to 1 × 10 ⁹ N / m ² is used for the base material of the input tip, in order to prevent damage to the input panel, a spherical or massive convex portion It is preferable that the rigidity of 1 × 10 ⁻⁴ to 1 × 10 ⁷ N / m ² is “soft”. On the contrary, when the rigidity of the base material of this input tip is as low as 1 × 10 ⁻⁴ to 1 × 10 ⁷ N / m ² , the rigidity of the spherical or massive convex portion is “higher”. 1 × 10 ⁻⁴ to 1 × 10 ⁹ N / m ² .

  Due to the presence of the spherical or massive convex portion on the surface of the input tip, when the touch pen of the present invention is pressed against the input panel, the contact area between the soft input tip and the input panel is reduced. Therefore, when the touch pen is slid on the input panel, the frictional resistance is reduced as compared with the case without the spherical or lump-shaped convex portion, and a smooth and quick input operation is possible. Depending on the thickness of the touch pen and the size of the input tip, the height that the spherical or massive convex part should protrude (the particle diameter of the spherical or massive convex part) is 1 mm or less. The probability that an error will occur is reduced. Preferably, if it is 0.5 mm or less, the error will not occur more.

  As a method of adhering such a spherical or massive convex part to the input tip surface, it is a very general process, that is, a method of applying an adhesive to the input tip surface and adhering the spherical or massive convex part appropriately. And a method of adhering an adhesive to the spherical or blocky convex portion and appropriately adhering it to the surface of the input tip.

  By the way, when it becomes possible to analyze the coordinates on the board surface of the input pad more finely due to the recent technical progress, even if it is a fine spherical or massive convex portion as described above, such a touch pen contact is not , There is a possibility that it is recognized as a contact only with the pressed spherical or blocky convex portion. This phenomenon is not a problem as long as it touches an icon or the like having a certain area. However, for example, when drawing a line with the full thickness of the touch pen when performing drawing, there is a problem.

  Therefore, such a problem can be solved by providing very fine fibrous convex portions on the surface of the input tip as in Patent Document 2 instead of the spherical or massive convex portions. That is, the countless, extremely fine fibrous convex portions come into contact with each other, so that it can be recognized as an input having a certain area as if the brushstroke touched. At this time, the user is also given a soft feel like drawing with a brush.

  Examples of such a fibrous convex material include natural fibers, animal hair fibers, polyacetal resins, acrylic resins, polyester resins, polyamide resins, polyurethane resins, polyolefin resins, polyvinyl resins, polycarbonates. Examples thereof include those made of a fibrous body made of one type or a combination of two or more types such as a series resin, a polyether series resin, and a polyphenylene series resin.

Of course, conductive fibers may be used for the fibrous convex portions. As shown in FIG. 1A, the conductive fiber is made conductive by coating the fiber (α) based on polyester resin, polyamide resin or the like with a conductive material (β). In addition, as shown in FIG. 1 (b), a material containing a conductive material (δ) in at least a part of the fibers (γ) constituting the conductive fiber bundle core is used. The resistance value of these fibers is desirably 10 ¹⁰ Ω / cm or less. These fibrous convex portions may be at least partially made of the conductive fibers, the rest may be made of the non-conductive fibers, or all of the fibers may be made of conductive fibers.

  The conductive material used for the conductive fiber is the same as the conductive material used for the base material of the input tip, that is, a conductive resin such as polypyrrole, polythiophene, polyethylenedioxythiophene, polyisothianaphthene, polyaniline is dispersed or dispersed. It is obtained by applying a solubilized resin solution to the convex portions and solidifying or heat-curing. Similarly, when using these conductive materials, 2,3,7,8-tetracyano-1,4,6,9-tetraazanaphthalene, dodecylbenzenesulfonic acid, A conductive resin to which a dopant such as p-toluenesulfonic acid is added can be used.

  Instead of the conductive material described above, a metal plating layer may be provided as shown in FIG. Examples of the metal of the metal plating layer include aluminum, zinc, gold, silver, copper, platinum, palladium, nickel, iridium, rhodium, cobalt, osmium, ruthenium, iron, etc. Gold, silver and copper are preferred.

Moreover, as a conductive material that can be used for the fibers, carbon black, graphite, metal particles, and the like, which are general conductive materials, can also be used. As described above, the fiber made of such a material as a whole may cause problems such as scratching the input panel. However, the surface of synthetic fiber such as polyester or polyamide may be covered, or a part of the fiber may have the above conductivity. When materials are used, such problems can be avoided by adjusting the flexibility of the fibers. For example, the fiber rigidity is preferably 1 × 10 ⁻⁴ to 1 × 10 ⁹ N / m ² , more preferably 1 × 10 ⁻⁴ to 1 × 10 ⁸ N / m ² , and even more preferably 1 × 10 ^−. The damage of the input panel can be avoided by setting to ⁴ to 1 × 10 ⁷ N / m ² . In addition, the general fiber thickness is 0.001 to 300 dtex, more preferably 0.001 to 30 dtex, and still more preferably 0.001 to 3 dtex, thereby providing a more flexible touch to the input panel. Can be obtained. The length of the pile (fiber to be planted) is not particularly limited as long as it is attached to the input tip base material, but a length of 0.1 to 3.0 mm can be suitably used. The thing of length of 0.1-1.5 mm can be used more suitably.

  As a method of adhering such a fibrous convex portion to the input tip surface, a very general process, that is, a method of applying an adhesive to the input tip surface and adhering the fibrous convex portion appropriately, fiber For example, there may be mentioned a method in which an adhesive is attached to the shape of the convex portion and appropriately adhered to the surface of the input tip.

  Further, as another bonding method, there is bonding by electrostatic flocking as described in Reference 2. After the adhesive is applied to the surface of the input tip, the input tip base material and the fibrous convex portion are charged to a pair of charges, and the fibrous convex portion is adhered to the input tip base material in a state where it stands. be able to. By this method, it is possible to obtain an input tip having a shape different from that of the normal process described above.

  In addition to the method for manufacturing the input tip as described above, a base portion can be provided and integrated with the base material. That is, a shaft is formed simultaneously with the base material of the input tip by a method such as forming a fused portion by a resin solution or the like at the rear end of the input tip, or bonding and fixing a resin plate or the like to the rear end of the input tip by a resin solution or the like A plane perpendicular to the direction can be formed. The resin solution or the resin plate described above may be a conductive material in order to ensure conductivity. The base can be flanged when provided at the rear end of the input tip.

  Moreover, you may insert a center core in the center part of the said input tip base material. By providing a central core in the center of the input tip base material, the mechanical strength such as the apparent bending strength of the input tip base material is greatly improved without changing the feel when the input tip touches the input panel. Can do. Examples of the core include a dense rod-shaped body, a rod-shaped body porous with a fiber bundle, and a rod-shaped body of a sintered product of particles. If it demonstrates from the side of physical properties, if it is a rod-shaped body which has the bending strength exceeding an input tip base material and has flexibility lower than an input tip base material, it can be used without a problem. Resin, metal, metal oxide, metalloid, metalloid oxide, etc. can be used for this core. Of these, resins are preferable from the viewpoint of moldability, and synthetic resins such as polyethylene, polypropylene, polyacetal, vinyl chloride, acrylic, and polycarbonate can be used. When the product according to the present invention prioritizes ensuring the conductivity, these cores can be made of a conductive material.

  The following forms can be considered as a method of inserting the core into the central portion of the input pointed base material. First, if the input tip has no base at the rear end and is made of a soft material such as a conductive resin, insert the core directly from the center of the rear end of the input tip base material. How to end up. Second, when the input tip is provided with a base at the rear end of the base material and is made of a hard material such as metal, an insertion hole for inserting the core is provided in the center of the base to insert the core. Method. Thirdly, this is also the case where the input tip is provided with a base at the rear end of the input tip base material, but with the shape in which the core is protruded from the center inside the base, the base and the core are integrally formed, A method of forming the input tip.

  If the shaft of the pen has a sufficiently large conductivity, the input tip base material containing the conductive material can be a capacitive coordinate input device or a display-integrated capacitive input even with a shaft made of a non-conductive material. Input to the device is possible. However, when the conductivity of the input tip base material is small, or when the response performance of the capacitive coordinate input device or the display-integrated capacitive input device is inferior, a synthetic resin shaft blended with carbon black, metal fine particles, etc. If the shaft body is made such that the gripping part of the shaft body and the pen nib are conductive by using a shaft made of a synthetic resin shaft surface or a shaft made of metal or conductive resin, the response is further improved. It becomes a good pen. In addition, the shaft body may be composed of a single component or a plurality of components such as a tip shaft, a shaft tube, and a tail plug as long as the grip portion of the shaft body and the pen tip have conductivity. Alternatively, the synthetic resin containing carbon black or metal fine particles is coated on the outer periphery of the member such as the tip shaft or the shaft tube, the plating is applied, the coating made of metal is applied, or the conductive The material may be coated with a functional material. For fixing the core, a core fixing tool may be provided. Furthermore, by storing conductive fibers, conductive sponges, metals, graphite sintered bodies, etc. in the shaft body so as to conduct with the pen tip, the volume of the conductor is increased. The responsiveness of the capacitive coordinate input device or the display-integrated capacitive input device can be adjusted as appropriate.

  When inputting coordinates to the capacitive coordinate input device or the display-integrated capacitive input device using the pen configured as described above, the user grasps the shaft body and sets the input tip to the electrostatic capacitance. Input is performed by pressing against a type coordinate input device or a display-integrated capacitance type input device. When the center core is inserted, it can be deformed by the repulsive force of the user's preference with a harder feeling than the case of only the input tip. As a result, an intended capacitance depending on an accurate contact area is formed between the capacitive coordinate input device or the display-integrated capacitive input device and the tip of the input tip. Is possible.

  If the input tip is configured by inserting a sintered or fiber bundle core into a relatively soft input tip base material, it can be used by adjusting the density, porosity, etc. of the core It becomes possible for the person to feel that the input is appropriate. That is, it becomes easy to adjust the bending strength and flexibility to desired values by changing the density, porosity, etc. of the core, and to make the “writing resistance” and “input feeling” appropriate for the user. At this time, by making the input pointed base material or the input pointed base material including the input pointed base material detachable, adjustment of “writing resistance” and “input feeling” by exchanging the core becomes easier.

  In addition, the fact that the input tip can be attached and detached facilitates replacement when the input tip base material deteriorates. The deterioration here refers to physical deterioration such as wear of the input tip base material and the convex portion or loss of the convex portion due to continued use, or oxidation or organicity of the conductive material constituting the input tip base material and the convex portion. Examples include solvent dissolution and swelling.

Also in this embodiment, since the input tip base material 21, the core 4 and the base portion 23 are integrated as an input tip, the user does not like "writing resistance" or "input feeling" at the input tip. By replacing the entire input tip with another one, the favorite “writing resistance” or “input feeling” can be obtained. At the time of this replacement work, when the input tip 2 is gripped by fingers, it is very easy to grip by the convex portion, and the replacement work is easy. In this example, the electrical resistance from the tip 22 to the gripping part 12 was measured, but it was impossible to measure exceeding the upper limit (10 MΩ) of the measuring instrument, but accurate input could be performed without any problem.

(Fifth embodiment)
FIG. 9 shows a fifth embodiment, which is configured to have a shaft 1 made of a conductive material and an input tip 2 including the input tip base material 21 of the conductive resin shown in the fourth example (the convex portion is shown in FIG. 9). Not shown). A hollow portion 27 is provided inside the input tip base material 21 and a flange-shaped contact portion 24 exists. The flange-shaped contact portion 24 of the input tip 2 and the input tip holding portion 11 of the shaft body 1 are joined, and the input tip 2 is held. The base material 21 is made of silicone rubber having a durometer type A hardness of about 60 ° according to JIS K 6253, and a nylon fiber whose surface is coated with silver plating as shown in FIG. It is flocked by electric flocking. The convex portion (fiber) 25 has a length of 1.5 mm, and the input tip 2 has an appearance like a Weifang head. The input touch pen configured as described above has a very soft feel when inputting, and has a very low resistance when sliding. If the user does not like “writing resistance” or “input feeling” due to dropping off of the fibrous convex portions 25, 25... Or “feeling of input”. At the time of this replacement work, when the input tip 2 is gripped by fingers, it is very easy to grip by the convex portion, and the replacement work is easy. In this embodiment, it is the structure connected from the fibrous convex part 25 of the front-end | tip 22 to the holding part 12 of the shaft body 1 through the input point holding | maintenance part 11 with the electroconductive material. However, although the electrical resistance from the tip 22 to the grip portion 12 was measured, the measured value fluctuated at a considerably high value, and a clear value could not be shown. However, there was no problem with the response to the input operation, and an accurate input could be performed.

(Sixth embodiment)
In the sixth embodiment shown in FIG. 10, the conductive core 4 inscribed in the hollow portion 27 of the input tip base material 21 shown in FIG. 5 is inserted so that the hollow portion 27 remains slightly at the tip, Except for the configuration in which the length of the fibrous convex portion 25 is set to 3.0 mm, the configuration is the same as that of the fifth embodiment. The input touch pen configured as described above has a very soft touch at the tip and a very low resistance when being slid. When pressing from the tip to a certain depth, excessive pressing is prevented by the sense of resistance received from the core 4 and the burden on the panel is reduced. Even in this embodiment, the electrical resistance from the tip 22 to the grip portion 12 was measured, but the measured value fluctuated at a considerably high value, and a clear value could not be shown. However, there was no problem with the response to the input operation, and an accurate input could be performed.

  As is clear from the above description, according to the electrostatic input touch pen of the present invention, when performing analog input from the input pad, that is, input such as drawing with a paintbrush or a marker, etc. Gives "writing resistance" and "feeling of input" and prompts correct input. Even if the user does not like these feelings, the “writing resistance” and “input feeling” can be easily adjusted by exchanging the input tip or the core.

  The product of the present invention can be used for adding and processing digital images, or inputting characters, handwriting, and pictures.
