  The present invention relates to an input touch pen and a manufacturing method thereof. In particular, the present invention relates to an input touch pen excellent in data input performance, operability, and the like and an efficient manufacturing method of such an input touch pen.

  For electronic devices equipped with touch panels and capacitive coordinate input pads, such as mobile tablets and smartphones, there are various touch pens for input that are compatible with the resistive film type and capacitive type due to the ease of use when inputting data. Proposed.

As such an input touch pen, for example, a touch pen intended to reduce scratches on the touch panel has been proposed (see, for example, Patent Document 1).
More specifically, as shown in FIG. 10, the touch pen 50 includes a pen body 51, accessory parts 52, 53, 54, 55, a pen shaft member 60, and a touch pen core 62, and the touch pen core 62 is detachably provided on the pen shaft member 60, is made of a soft conductive fiber material, and includes a generally elliptical pen tip (pen nib) when viewed in cross section from the lateral direction. It is configured as such.

In addition, there has been proposed a touch pen that uses conductive rubber for a pen tip and further ensures conduction from a touch panel to a finger through a conductive shaft (Patent Document 2).
More specifically, as shown in FIG. 11, a conductive pen body 100 held by the user's hand, a conductive pen tip 102 electrically connected to the pen body 100, and a clip 103, , And an input pen 105 for inputting coordinate information to a capacitive coordinate input pad, wherein the pen tip 102 is made of a conductive material made of a rubber material blended with conductive carbon black or metal powder. This is an input pen 105 made of rubber.

In addition, a conductive carbon fiber and a resin fiber are blended to form a fiber bundle, which is further solidified using a resin binder, and the conduction from the touch panel to the finger is ensured through a conductive shaft. A touch pen has been proposed (Patent Document 3).
More specifically, a conductive pen body held by the user's hand and a conductive pen tip electrically connected to the pen body are provided, and coordinate information is input to the capacitive coordinate input pad. In an input pen for a capacitive coordinate input pad that enables input of a pen, the pen tip is composed mainly of a fiber bundle in which conductive carbon fibers and resin fibers are blended, and a resin binder is interposed therein. This is an input pen for a capacitance type coordinate input pad.

Furthermore, a touch pen intended to improve operability has also been proposed (see, for example, Patent Document 4).

However, the input touch pen provided with the pen nib made of the soft conductive fiber material of Patent Document 1 is easily deformed by the frictional force with the input surface, so that the pen nib falls off. There was a problem that the input error tends to increase.
Further, the input touch pen using the conductive rubber for the pen tip of Patent Document 2 has a large frictional force with the input surface, the conductive rubber is deteriorated, falls off the pen tip, and the resistivity changes. In some cases, it was difficult to input correctly.

  In addition, an input touch pen using a fiber bundle formed by blending conductive carbon fiber and resin fiber of Patent Document 3 and binding the resin fiber by thermal welding of a resin binder or resin fiber is used as an input surface. There was a problem that the frictional force between them was large, the fiber bundle of the nib deteriorated, and it was easy to fall off from the nib. In addition, the resistivity of the fiber bundle varies or changes, and there is a problem that it is difficult to input normally.

  Furthermore, in the touch pen formed by implanting a plurality of conductive fibers having a predetermined length or the like described in Patent Document 4, the pen tip is easily deformed due to the frictional force with the input surface, and the input error tends to increase. The problem was seen. In addition, it is necessary to plant a plurality of conductive fibers having a predetermined diameter and length on the surface of the touch pen body, and there is a manufacturing problem that the manufacturing time tends to be excessively long. It was.

Accordingly, the inventors of the present invention have made extensive efforts to provide an input touch pen that includes at least a shaft core and a pen container surrounding the shaft core, and is formed of a conductive fiber at the tip of the shaft core. Then, a cylindrical object (hereinafter sometimes simply referred to as a cylindrical object) whose one end is closed by a joint part (a seam by sewing, a welded part by ultrasonic welding, or an adhesive part) is inserted. Yes, the cylindrical object and the shaft core are connected and fixed by the connection fixing member, and it is found that the above-mentioned problem can be solved by providing a conductive state between the cylindrical object and the shaft core. The invention has been completed.
That is, an object of the present invention is to provide an input touch pen excellent in data input performance, operability, and the like and an efficient manufacturing method of such an input touch pen.

An input touch pen including at least a shaft core and a pen container surrounding the periphery thereof, and a cylindrical object formed of a conductive fiber at a tip portion of the shaft core and closed at one end by a joint portion Is provided, the cylindrical object and the shaft core are connected and fixed, and a conductive state is provided between the cylindrical object and the shaft core. Can be solved.
In other words, since the cylindrical object with a predetermined configuration is fixed to the tip of the shaft core, the friction between the touch panel and the like is reduced, the writing pressure is stabilized, and as a result, smooth input is possible. Good operability and data input property can be obtained.
In addition, if it is a long bag-like cylinder formed from conductive fibers, it easily elastically deforms following the use operation of the input touch pen, without damaging the surface of the touch panel, etc., and Since it is elastically deformed moderately, the touch area between the touch panel and the like is increased, the pressing force is made uniform, and as a result, good durability and accurate data input property can be obtained.
In addition, since the cylindrical structure with a predetermined configuration is made of conductive fibers, it can also function to remove dust adhering to the surface of touch panels, etc., and to remove static electricity, and to provide more accurate data input properties. Can be obtained.

Further, in configuring the input touch pen of the present invention, it is preferable that a cushion member (buffer member) is inserted between the cylindrical object and the tip of the shaft core.
In this way, through the cushion member, by inserting the cylindrical object whose one end is closed by the joint portion, excessive deformation of the cylindrical object is suppressed, or between the cylindrical object and the shaft core, Further, it can be press-fitted and fixed in close contact, and as a result, more accurate data input property can be obtained in correspondence with a high-definition touch panel or the like.
In addition, although depending on the size and length of the cushion member (buffer member), a space can be formed between the tip of the shaft core and the cushion member.
Therefore, due to the internal pressure in the space, not only the cushion member but also the cylindrical object is easily elastically deformed to follow the use operation of the input touch pen, thereby obtaining more accurate data input property. Or excellent durability can be obtained.

In configuring the input touch pen of the present invention, it is preferable to set the diameter of the tip of the shaft core to a value in the range of 0.5 to 5 mm.
By limiting the diameter (equivalent circle diameter) of the tip of the shaft core to such a range, when a cylindrical object whose one end is closed by a joint is inserted, the diameter of the tip can be easily controlled. In addition, the frictional force (writing pressure) between the touch panel and the like is moderate, and smooth and high-speed data input is possible. Input property can be obtained.

In configuring the input touch pen of the present invention, it is preferable to set the outer diameter of the cylindrical object to a value in the range of 0.5 to 5 mm.
By limiting the outer diameter of the cylindrical object to such a range, it is possible to press fit with the tip of the shaft core, and in turn, it becomes easier to control the diameter of the tip, enabling smoother and faster input. In addition, more accurate data input property can be obtained even if it corresponds to a high-definition touch panel or the like.

In configuring the input touch pen of the present invention, it is preferable that the cylindrical object and the shaft core are fixed using a heat-shrinkable tube.
By using a heat-shrinkable tube in this way, the cylindrical object and the shaft core can be fixed uniformly and quickly, and as a result, smoother input is possible, as well as high-definition touch panels. Thus, more accurate data input property can be obtained.
In addition, the use of a heat-shrinkable tube improves the accuracy of fixing the cylindrical object and the shaft core during manufacturing, and it is quicker to reduce the manufacturing cost of the input touch pen, and to reduce the manufacturing time. It can be shortened.

Further, in configuring the input touch pen of the present invention, it is preferable that the front and back of the cylindrical object are turned over and closed by the joint, and the joint is located inside.
By configuring in this way, the joint part (seam, weld part, etc.) by the joint part (thread, ultrasonic wave, etc.) is located on the front side, and does not become an obstacle when operating the input touch pen. Input is possible.
In addition, since the joint portion is located on the inner side (back side) of the cylindrical object, it is possible to suppress the occurrence of so-called lint, and to obtain more accurate data input property corresponding to a high-definition touch panel or the like. be able to.

Further, in configuring the input touch pen of the present invention, it is preferable to set the resistivity of the conductive fiber constituting the cylindrical body to a value within the range of 1 × 10 ¹ to 1 × 10 ¹² Ω · cm.
By limiting the resistivity of such conductive fibers to a predetermined range, it is possible to achieve a good balance between accurate data input performance in the input touch pen and durability and manufacturability.

Another aspect of the present invention is a method for manufacturing an input touch pen including at least a shaft core and a pen container surrounding the shaft core, the touch pen being formed from a conductive fiber, and having one end closed by a joint. At the same time, a step of preparing a cylindrical object with one end opened, a step of inserting the cylindrical object into the tip of the shaft core through the opened one end, and connecting and fixing the cylindrical object and the shaft core A method of manufacturing a touch pen for input, comprising: a step of connecting and fixing by a member; and a step of bringing a cylindrical object and a shaft core into a conductive state.
That is, according to the input touch pen obtained, the long bag-shaped cylindrical object formed from the conductive fiber is fixed to the tip of the shaft core, so that the use operation of the input touch pen can be followed. Because it easily elastically deforms without damaging the surface of the touch panel and the like and moderately elastically deformed, the touch area between the touch panel and the like increases, and the pressing force is made uniform, As a result, good durability and accurate data input property can be obtained.
Moreover, according to the obtained touch pen for input, since the long bag-shaped cylindrical object formed from the conductive fiber is formed from the predetermined conductive fiber, dust attached to the surface of the touch panel or the like is removed. And the function of removing static electricity can be exhibited, and more accurate data input property can be obtained.
In addition, according to the input touch pen obtained, it has a simple configuration including a connection fixing member, the accuracy of fixing the cylindrical object and the shaft core at the time of manufacture is improved, and the input becomes faster.

[First Embodiment]
As illustrated in FIG. 1 and FIG. 2A, the first embodiment is an input touch pen 10 including at least a shaft core 12 and a pen container 14 surrounding the shaft core 12. A cylindrical object 18 formed of conductive fibers and having one end closed by a joint is inserted into the distal end of the cylindrical member 18. The cylindrical object 18 and the shaft core 12 are connected and fixed by a connection fixing member 16. In addition, the touch pen 10 for input is characterized in that the tube 18 and the shaft core 12 are in a conductive state.
Hereinafter, an input touch pen according to a first embodiment of the present invention will be specifically described with reference to the drawings as appropriate.

1. The shaft core 12 illustrated in FIG. 1 is housed inside the pen container 14 and normally protrudes outside the pen container 14 when in use, and is housed inside the pen container 14 when not in use. As shown in (b), it is a main member for inputting data to, for example, the touch panel 28 via the cylindrical object 18.

Here, it is preferable to set the diameter of the tip portion of the shaft core 12 to a value within the range of 0.5 to 5 mm.
The reason for this is that by limiting the diameter of the tip of the shaft core to such a range, not only the attachment of a predetermined cylindrical object becomes easy, but also the friction between the touch panel and the like via the cylindrical object is reduced. This is because it becomes smaller. Therefore, not only smooth data input by the shaft core is possible via a predetermined cylindrical object, but also data input can be performed accurately in correspondence with a high-definition touch panel or the like.
Therefore, the diameter of the tip of the shaft core 12 is more preferably set to a value within the range of 1 to 3 mm, and further preferably set to a value within the range of 1.2 to 2 mm.

2. Pen Container A pen container 14 illustrated in FIG. 1 and FIG. 2A is a casing for enclosing the periphery of the shaft core 12, and a cylindrical object 18 that protrudes from the tip of the input touch pen 10. This is a main member for gripping the input touch pen 10 when data is input to an arbitrary portion of the touch panel 28 via.
Here, the embodiment of the pen container 14 is not particularly limited. For example, as shown in FIG. 1, the pen container 14 may have a substantially cylindrical outer shape, or FIG. ), A ball-point pen type provided with a clip portion 24 and a knock portion 26 may be used.
In any pen container 14, since the usability is good, it is preferable that a spring member 20 for taking the cylindrical object 18 in and out of the pen tip is provided behind the inner wall of the pen container 14. .
In addition, when a predetermined voltage is applied to the touch panel via the input pen for a touch panel, it is preferable that an electrical wiring 22 for electrical connection with an external power source is provided in a part of the pen container 14.

3. Cylindrical material (1) Conductive fiber The conductive fiber constituting the cylindrical material 18 illustrated in FIGS. 1 and 2 is, for example, a conductive composition composed of a polymer material and a conductive material. Conductive fiber (conductive polymer-containing polymer fiber) made of a material, conductive fiber (conductive coated polymer fiber) formed by coating a conductive material on the surface of a polymer material, or conductive fiber made of a metal material ( It is basically composed of metal fibers).

  Here, the type of the polymer material is not particularly limited, and examples thereof include cotton, pulp, silk, rayon, cupra, polyester, polyamide, polyacryl, polyolefin (including polyethylene and polypropylene), and polyvinyl alcohol. , Polyvinyl chloride, polypropylene, lyocell and the like are preferably used alone or in combination of two or more.

And it is a polymer material having a melting point and a glass transition point in the range of 60 to 200 ° C., for example, because it can be thermocompression-bonded and ultrasonic welded in a short time and has predetermined mechanical properties. It is more preferable.
Therefore, it is preferable to use one kind or a combination of two or more kinds of cotton, polyester, polyamide, polyacryl, polyethylene, polypropylene, polyvinyl alcohol, and polyvinyl chloride.

In addition, the conductive fiber layer composed of the conductive composition or the conductive spinning body is not particularly limited as long as it is a sheet-like material having flexibility and shape followability. For example, a woven fabric, a knitted fabric, a nonwoven fabric, and papers are used. preferable.
That is, with such a form of fiber layer, a predetermined cushioning property and moderate deformability can be obtained, and when an input touch pen cylinder is formed, an appropriate sliding property is provided for the input screen. As a result, accurate data input becomes possible.
And since it is comparatively cheap and sliding property is favorable, it is more preferable to comprise a conductive fiber layer from a woven fabric or a nonwoven fabric.

(2) Conductive material In addition, conductive materials used for conductive fibers include gold, silver, copper, nickel, iron, stainless steel, zinc, tungsten, chromium, zirconium, sud, titanium, aluminum, solder, carbon , A single type of semiconductor material or a combination of two or more types.
In particular, because it is relatively inexpensive and has excellent conductivity, a metal material such as copper, nickel, and stainless steel, or a carbon compound material such as charcoal, carbon, and kevlar is blended inside the high molecular weight material. It is preferable to adhere to the surface of the high molecular weight material by a known lamination method such as a vapor deposition method, a sputtering method, a plating method, or a printing method.

(3) Diameter Moreover, it is preferable to make the spinning diameter at the time of forming a conductive fiber into the value within the range of 0.1-50 micrometers.
This is because, when the spinning diameter of the conductive fiber is less than 0.1 μm, it may be difficult to handle or the mechanical strength may be reduced.
On the other hand, when the spinning diameter of the conductive fiber exceeds 50 μm, the flexibility and the shape followability may be lowered when the input touch pen is configured.
Therefore, the spinning diameter of the conductive fiber is preferably set to a value within the range of 1 to 30 μm, and more preferably set to a value within the range of 3 to 20 μm.

(4) Resistivity Moreover, it is preferable to make the resistivity (volume resistance) of the conductive fiber which comprises a cylindrical thing into the value within the range of 1 * 10 < ¹ > -1 * 10 < ¹² > (omega | ohm) * cm.
The reason for this is that by limiting the resistivity of such conductive fibers to a predetermined range, it is possible to achieve a good balance between accurate data input property and durability or manufacturability. .
In other words, when the resistivity of the conductive fiber is less than 1 × 10 ¹ Ω · cm, the types of conductive materials and fiber materials used to constitute the conductive fiber are excessively limited, and data input is not possible. This is because it may be inaccurate.
On the other hand, when the resistivity of the conductive fiber becomes a value exceeding 1 × 10 ¹² Ω · cm, it may be difficult to input data accurately.
Therefore, the resistivity of the conductive fiber is preferably set to a value in the range of 1 × 10 ² to 1 × 10 ¹¹ Ω · cm, and the value in the range of 1 × 10 ³ to 1 × 10 ¹⁰ Ω · cm More preferably.
In addition, the resistivity (specific resistance) of the conductive fiber can be measured according to a four-terminal method using a digital voltmeter or the like.

(5) Diameter In addition, the outer diameter (L1) of the cylindrical object 18 illustrated in FIGS. 1 and 3 is equivalent to the size of the tip (equivalent circle diameter), and the diameter and length of the inserted shaft core. Although it is preferable to determine the thickness, it is usually preferable to set the value within the range of 0.5 to 5 mm.
The reason for this is that by limiting the outer diameter of the cylindrical object to such a range, there is almost no gap between the tip of the shaft core, and thus smoother input is possible, and high definition is possible. This is because more accurate data input property can be obtained in response to the touch panel of the above.

More specifically, when the outer diameter (L1) of the cylindrical object is a value of less than 0.5 mm, the friction with respect to the touch panel is improved, the usability is reduced, and it is difficult to manufacture with high accuracy. This is because there may be cases.
On the other hand, if the outer diameter (L1) of the cylindrical object exceeds 5 mm, the accuracy of pen input may be remarkably reduced or the fixability may be difficult.
Therefore, the outer diameter (L1) of the cylindrical object is more preferably set to a value within the range of 1 to 3 mm, and further preferably set to a value within the range of 1.2 to 2 mm.
In addition, when it corresponds to a high-definition touch panel, while making the diameter of the front-end | tip part of the axial center mentioned above into the value within the range of 0.4-1.5 mm, the outer diameter (L1) of a cylindrical thing is set. A value in the range of 0.4 to 1.5 mm is more preferable.

(6) Length The length (L2) of the cylindrical object 18 illustrated in FIGS. 1 and 3 is also determined in consideration of the diameter and length of the shaft core to be inserted or usability. Although it is preferable, it is usually preferable to set the value within a range of 5 to 50 mm.
The reason for this is that by limiting the length of the cylindrical object to such a range, not only smooth data input is possible, but also high precision touch panels etc. can be used for more accurate data input performance. This is because it can be obtained.

More specifically, when the length of the cylindrical object becomes a value of less than 5 mm, the deformability of the cylindrical object decreases, and smooth input may become difficult or durability may decrease. It is.
On the other hand, when the length of the cylindrical object exceeds 50 mm, on the contrary, the deformability of the cylindrical object becomes excessively large, and it becomes difficult to input more accurate data corresponding to a touch panel or the like. This is because there are cases.
Therefore, the length (L2) of the cylindrical object is more preferably set to a value within the range of 10 to 30 mm, and further preferably set to a value within the range of 15 to 20 mm.

(7) Tip shape The tip shape of the cylindrical object is not particularly limited. However, as shown in FIG. 3, the cylindrical shape is obtained by weaving, knitting, or pressure deformation treatment of conductive fibers. Alternatively, as shown in FIGS. 4A to 4D, a conical shape, an elliptical shape, a quadrangular prism shape, a hemispherical shape, or the like is preferable.
Moreover, although not shown in figure, it is also preferable to use these combinations, other flat shape, fan shape, spherical shape, etc.
For example, by making the tip of the cylindrical object flat (the vertical and horizontal lengths are different), fine writing and vertical writing are smooth and thick depending on the input application to the touch panel. This is because an input touch pen capable of different line inputs can be obtained.
That is, by using a flat cylindrical object, a plurality of characters, lines, etc. having a predetermined width can be input quickly and accurately.
Further, with such a flat cylindrical object, it is possible to perform sewing and ultrasonic welding with high accuracy, and to make the seam and the welded portion more inconspicuous.
Accordingly, the tip shape of the cylindrical object is made flat, the horizontal length is made longer than the vertical length, the horizontal length is set to a value within the range of 0.5 to 1.5 mm, and the vertical length is set to 0.2. It is preferable to set it as the value within the range of -1.0 mm.

On the other hand, even if the cylindrical tip shape is a cylindrical object such as a quadrangular prism shape, a conical shape, or a cylindrical shape, the manufacturing becomes easy and the adjustment of the contact property with the touch panel becomes good. Since the input touch pen can be moved more smoothly, it is a suitable tip shape.
In addition, the hemispherical, spherical, or elliptical shape makes it easy to adjust the contact area with the touch panel, enables smooth data input, and significantly increases the durability of the cylindrical object. Since it can do, it is a suitable tip shape.
In addition, by using a fan-shaped cylindrical object, as a kind of flat shape, it is possible to input data of a plurality of predetermined width characters and lines quickly and accurately, and in addition, the contact area between the touch panel Since the adjustment is also easy, it is a suitable tip shape.

(8) Cushion Member Moreover, as shown in FIG. 5B and the like, it is preferable that a cushion member 30 is inserted between the cylindrical object 18 and the shaft core 12.
The reason for this is that the cylindrical object is inserted through the cushion member in this way, so that the cylindrical object and the shaft core can be further closely connected and fixed. This is because the durability of the object can be further improved.
In addition, by interposing the cushion member in this manner, not only smoother input is possible, but also more accurate data input performance can be obtained corresponding to a high-definition touch panel or the like.

And in the case of the cushion member 30 shown in FIG. 5 (b), the end is open and the other end is a closed hemisphere, but this is as shown in FIG. 5 (a). Furthermore, it is preferable that the inner surface of the hemispherical end portion is covered with a needle-like object 12a provided at the tip end portion of the shaft core 12 in a state of being pierced.
The reason for this is that, when the cushion member 30 is made of a conductive material, the adhesiveness between the cylindrical body 18 and the shaft core 12 is enhanced via the cushion member 30 and the cushion member 30 is made of a conductive material. This is because electrical connection between the cylindrical object 18 and the shaft core 12 can be ensured more reliably.

Here, the aspect of the cushion member is not particularly limited, but is made of a fiber material such as cotton, pulp, silk, rayon, cupra, polyester, polyamide, polyacryl, polyolefin, polyvinyl alcohol, polyvinyl chloride, or foam. It is preferably composed of at least one of soft materials such as urethane, foamed styrene, natural rubber material, synthetic rubber material, silicone rubber material, and fluorine material.
These cushion members are also made of a predetermined conductive material, for example, a conductive material having a resistivity (volume resistance) of 1 × 10 ⁰ to 1 × 10 ³ Ω · cm, via the shaft core, Electrical connection between the conductive cylinder and the outside can be easily achieved.
In particular, fiber materials such as cotton, soft materials such as urethane foam and silicone rubber, and metal meshes are not only easy to impart conductivity, but also have a predetermined cushioning property over a long period of time. A cushion member that can be maintained and that is suitable and inexpensive can be configured.

And when providing a cushion member between a cylindrical thing and the front-end | tip part of an axial center, it is preferable to make the thickness into the value within the range of 0.05-3 mm normally.
This is because when the cushion member has a thickness of less than 0.05 mm, a predetermined cushion effect may not be obtained.
On the other hand, if the thickness of the cushion member exceeds 3 mm, it may be difficult to insert the cylindrical object, or it may be difficult to process the tip shape of the cylindrical object.
Therefore, the thickness of the cushion member is more preferably set to a value within the range of 0.1 to 1.2 mm, and further preferably set to a value within the range of 0.3 to 0.8 mm.

Further, as shown in FIG. 6 (a), a semispherical shaft core 12 is prepared, and then, as shown in FIG. 6 (b), the end is opened and the other end is closed. A cylindrical cushion member 30 is inserted into the prepared shaft core 12, and a predetermined volume (for example, 0.1 to ⁵ cm ³ ) is provided between the tip of the shaft core 12 and the hemispherical inner surface of the cushion member 30. It is also preferable to provide a predetermined space 30 ′ having
At this time, the cushion member 30 is made of silicon rubber, natural rubber, nitrile rubber, styrene rubber, olefin rubber, fluorine rubber, or the like having a predetermined thickness (for example, 0.1 to 1.0 mm). It is preferable that the predetermined space is formed from a rubber material having a relatively large elastic force.
Moreover, if it is the cushion member 30 comprised from such a rubber material, as shown in FIG.6 (c) and (d), while it is elastically deformed moderately and surface smoothness is favorable, it is cylindrical. The object 18 can be easily inserted, and the connection fixing means 16 can be easily and accurately fixed.

4). Connection fixing means As shown in FIG. 1 or FIGS. 7 (c) to (d), the connection fixing means 16 with respect to the shaft core 12 of the cylindrical object 18 is not particularly limited. At least one of an agent, an adhesive tape, a caulking member, and a heat shrinkable tube.
In particular, if the connection fixing means 16 is a heat-shrinkable tube as shown in FIGS. 7 (c) to (d), the volume is shrunk by heating at a predetermined temperature for a predetermined time. This is a preferable mode because it can be instantaneously fixed to the shaft core.
Moreover, even if the predetermined cylindrical object is deteriorated by use for a long time, if it is fixed using the heat shrinkable tube shown in FIGS. 7 (c) to (d), The advantage that a predetermined cylindrical object can be easily exchanged for a new one can be obtained.

Here, the aspect of the heat-shrinkable tube 16 shown in FIGS. 7C to 7D is not particularly limited, but the diameter of the heat-shrinkable tube before shrinking is 3 to 10 mm, and the length before shrinking is 3 It is preferable that the thickness (wall pressure) before shrinkage is 0.1 to 8 mm.
And it is preferable that the diameter of the heat-shrinkable tube after shrinkage is 0.5 to 5 mm, the length after shrinkage is 2 to 30 mm, and the thickness (wall pressure) after shrinkage is 0.1 to 5 mm.
In addition, such a heat-shrinkable tube is composed of at least one of heat-shrinkable polyester resin, heat-shrinkable polyurethane resin, heat-shrinkable acrylic resin, heat-shrinkable olefin resin, heat-shrinkable silicone resin, and the like. It is preferable.

5. Input Touch Pen (1) Configuration FIGS. 1 and 2A are schematic diagrams for explaining the configuration of the input touch pen of the present invention.
That is, the input touch pen of the present invention is any input touch pen as long as it can be suitably used as an electrostatic capacity type pad input pen, a resistance type pad input pen, or an electromagnetic induction type input pen. May be.

(2) Performance 1
Next, the performance of the input touch pen of the present invention will be described with reference to FIG.
The horizontal axis of FIG. 8 shows the diameter of the tip (equivalent to a circle), and the left vertical axis shows the writing pressure of the input touch pen relative to the input screen (relative value, usually 0 to 120 g / mm ^2). ), And the right vertical axis indicates the durability of the input touch pen.
The line A is a characteristic curve showing the relationship between the diameter of the tip (equivalent to a circle) and the writing pressure (pressing force) of the input touch pen on the input screen,
Here, the writing pressure of the input touch pen can be easily measured using a pressure gauge or the like, or simply, the weight of the input touch pen and the diameter of the tip (equivalent to a circle) It can also be calculated from the size of.
When the diameter (equivalent to a circle) of the tip part (mm) becomes relatively thin or thick from line A, the pen pressure on the input screen is significantly reduced. It can be understood that it affects the characteristics or durability.
For example, when the writing pressure on the input screen is excessively high, the operability of the input touch pen is reduced, and the durability is reduced.
On the other hand, if the writing pressure on the input screen is low, the operability and durability of the input touch pen are improved, but if it is excessively low, the input characteristics are remarkably deteriorated.

On the other hand, line B is a characteristic curve showing the relationship between the diameter of the tip (equivalent to a circle) and the durability of the input touch pen (relative value, usually 0 to 12000 times). In addition, durability is performed according to the evaluation criteria shown in Example 1, and an actual numerical value can also be calculated.
From line B, it is understood that excellent durability can be obtained in the range shown (0.5 to 3.5 mm) regardless of the size (mm) of the diameter (equivalent to a circle) of the tip. Is done.
If the tip diameter (equivalent to a circle) is 8 mm, the durability is reduced by less than 1000 times. If the tip diameter (equivalent to a circle) is 5 mm, the durability is reduced by less than 5000 times. It has been found separately.
Further, when the cylindrical object and the shaft core in the input touch pen are not connected and fixed by the connection fixing member, the durability (regardless of the size (mm) of the diameter (equivalent to a circle) of the tip part, It has been separately found that it decreases with less than 1000 uses.

(3) Performance 2
Next, the data input property of the input touch pen of the present invention will be described with reference to FIG.
The horizontal axis of FIG. 9 shows the diameter (equivalent to a circle) of the tip, and the left vertical axis shows the data input property (%) by the input touch pen for the input screen.
Line A has a cushion layer (silicone rubber layer) and corresponds to Example 6, and line B does not have a cushion layer and corresponds to Example 6.
And according to line A, it seems that it has a predetermined cushion layer, but when the size (mm) of the diameter (equivalent to a circle) of the tip is relatively thin to thick, it corresponds to the input screen. It is understood that the data input property is slightly lowered, but maintains a good level within a considerable range.
On the other hand, according to the line B, it seems that it does not have a predetermined cushion layer, but when the size (mm) of the diameter (equivalent to a circle) of the tip is relatively thin to thick, the data for the input screen It is understood that the input property is reduced accordingly.
In any case, although the structure is somewhat complicated and the number of manufacturing processes is increased by one, it is possible to provide a predetermined cushion layer between the tip of the shaft core and the cylindrical object. It is understood that it is advantageous in maintaining the data input property with respect to a good input screen even in a case where is slightly changed.

[Second Embodiment]
A second embodiment of the present invention is a method of manufacturing an input touch pen including at least an axis and a pen container surrounding the periphery thereof, and includes the following first to fourth steps. This is a method for manufacturing an input touch pen.
1st process: The process which prepares the cylindrical object which was formed from the electroconductive fiber, and the one end was closed by the junction part, and the one end was open | released (it may be hereafter called the preparation process of a cylindrical object).
2nd process: The process of inserting a cylindrical object into the front-end | tip part of an axial center via an open end (Hereinafter, it may be called the insertion process of a cylindrical object.)
Third step: A step of connecting and fixing the cylindrical object and the shaft core with a connection fixing member (hereinafter, sometimes referred to as a fixing step of the cylindrical object).
4th process: The process which makes a conductive state between a cylindrical thing and an axial center (henceforth a conduction process may be called).
Hereinafter, the manufacturing method of the touch pen for input which is 2nd Embodiment of this invention is demonstrated concretely, referring the manufacturing process figure shown to Fig.7 (a)-(d).

1. First Step: Cylindrical Preparatory Step The first step of preparing the cylindrical member 18 is one of the constituent materials of the input touch pen as shown in FIG. This is a step of preparing a cylindrical object 18 in which the end portion 18a is open while the other end portion 18b is closed by the joint portion 18c.
For example, a cylinder as a cylindrical bag-like material having an arbitrary diameter and length by folding two woven fabrics or non-woven fabrics, and ultrasonically welding the tip and side surfaces, or sewing them with a thread. Forms can be formed.
At this stage, since the joint portion 18c (seam or welded portion) of the cylindrical object 18 is usually located outside, the front and back of the tubular object 18 are reversed and the joint portion 18c is located inside. Is preferred.

2. Second step: Inserting process of cylindrical object Next, the inserting process of the cylindrical object 18 as a second process is as shown in FIG. This is a step of inserting the opened one end, that is, the open end 18a, and the cylindrical object 18 having the opposite end closed, that is, the closed end portion 18b, through the open end 18a.
At this time, as described above in part, the front and back of the cylindrical object 18 are reversed using a needle-shaped jig, and the joining portion (seam or welded portion) 18c is located inside the cylindrical object 18. It is preferable that
The reason for this is that, by configuring the predetermined joint portion so as to be located not on the outside but on the inside, the joint portion does not become an obstacle to operation, and smoother input becomes possible.
In addition, since the joint is located on the inner side, so-called lint generation can be suppressed, and more accurate data input property can be obtained in correspondence with a high-definition touch panel or the like.

3. Third Step: Cylindrical Fixing Step Next, the fixing step of the cylindrical product 18 as a third step is a step of connecting and fixing the cylindrical product 18 and the shaft core 12 by the connection fixing member 16.
As such a connection fixing member 16, for example, it is also preferable to use an adhesive such as an acrylic adhesive, a urethane adhesive, a polyester adhesive, an epoxy adhesive, or a cylindrical heat-shrinkable tube. The heat shrinkable tube may be contracted by heating under predetermined conditions, and the cylindrical object and the shaft core may be connected and fixed.
That is, as shown in FIG. 7 (c), a heat-shrinkable tube having a predetermined shape, which is the connection fixing member 16, is further covered around the shaft core 12 into which the cylindrical object 18 is inserted, and then, FIG. As shown in FIG. 2, it is preferable that the heat-shrinkable tube is heated from the surroundings and thermally contracted to connect and fix the cylindrical object 18 and the shaft core 12.

4). 4th process: Conducting process The conducting process as the 4th process is a process which makes a conductive state between a cylindrical thing and a shaft core although it is not illustrated.
That is, it is for providing an electrical wiring or a conductive path between the cylindrical object and the shaft core (tip end portion of the shaft core) and inputting the electrical signal to the touch panel using an input touch pen.

5. Other 1
It is preferable to appropriately provide a static electricity removing step and a fine fiber removing step.
The reason for this is that when the cylindrical object has a predetermined conductivity, when joining one end of the cylindrical object, the front and back of the cylindrical object are reversed using a needle-shaped jig and bonded. In the process where the portion (seam or welded portion) is located inside the cylindrical object, predetermined static electricity may be generated or fine fibers (linen) may be removed from the fiber, and these may be removed. preferable.
Therefore, it is preferable to remove these in advance by spraying charged air using an ionizer (manufactured by 3M, USA) or spraying a high-speed jet stream for a predetermined time.
In other words, if the cylindrical object is charged or fine fibers (linen) are attached, it is easy to collect dust and dust, and as a result, the data input property of the input touch pen may deteriorate. Because.
In addition, although it is effective to implement the static electricity removal process and the fine fiber removal process between the second process and the third process, before the first process, the first process and the second process. , Between the third step and the fourth step, or after the fourth step.

6). Other 2
It is also preferable to prepare a flat oval shape shown in FIG. 4B as the cylindrical object 18 and insert it around the shaft core 12.
That is, it is because the distal end portion after insertion can be made flat by making the distal end shape of the cylindrical object a flat oval shape (the vertical and horizontal lengths are different).
Therefore, according to the input application to the touch panel, the direction of the input touch pen can be changed as appropriate so that fine writing and vertical writing can be performed smoothly and line input with different thickness can be made. it can.
