  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an enlarged cross-sectional view of the distal end side of a stylus pen 1 as a pen-type input device. 2A and 2B show the entire stylus pen 1, wherein FIG. 2A is a side view and FIG. 2B is a longitudinal sectional view. FIG. 3 is a perspective view of the mobile terminal 21 as viewed from the front side, and FIG. 4 is a perspective view of the mobile terminal 21 as viewed from the back side. FIG. 5 is an enlarged perspective view showing the stylus pen 1 housed in the pen housing portion and its periphery. FIG. 6 is an enlarged perspective view showing the protrusion of the pen housing portion and its periphery. The stylus pen 1 for a touch panel according to the present embodiment is a device that inputs by making contact with the capacitive touch panel 22 of the mobile terminal 21.

  The mobile terminal 21 is, for example, a smartphone, and is provided such that a rectangular touch panel 22 is fitted into a rectangular plate-shaped housing 23 on the front. The surface of the touch panel 22 is covered with, for example, a glass panel, an acrylic panel, a film for preventing scattering. The rear side of the housing 23 is covered with a rectangular dish-shaped rear cover 24. The rear cover 24 also covers the rechargeable battery 25. A pen housing portion 26 formed of a long and narrow recess for housing the stylus pen 1 is formed on the outer periphery of the rechargeable battery 25 of the housing 23 exposed when the rear cover 24 is removed. The pen housing portion 26 is formed with a projection 27 that fits into the lower caulking portion 9 described later. Further, a locking portion 28 that locks to the outer periphery of the stylus pen 1 is also formed.

  The stylus pen 1 includes a metal rod-shaped pen core 2. The pen core 2 is, for example, a stainless steel round bar to ensure strength, but any material can be used as long as it is a conductive metal. Depending on the case, a conductive resin material having high strength may be used. At the tip of the round bar, a retaining portion for preventing the pen point protecting member 5 from falling off is formed. In the present embodiment, the retaining portion is composed of a bent portion 2a obtained by bending the tip of the metal rod.

  A cylindrical holding material 3 made of, for example, brass having good conductivity is fixed to the base end side of the pen core 2 by caulking. The holding material may be another metal as long as it is a highly conductive metal such as copper or aluminum, and a light metal such as aluminum is advantageous because it is lightweight and easy to process. Alternatively, a relatively strong synthetic resin or rubber containing a large amount of conductive powder such as carbon may be used. The holding material 3 is covered with a pen shaft 4 made of a hollow metal cylinder member in a state of covering the proximal end side of the pen core 2 including the holding material 3. The pen shaft 4 is made of, for example, a stainless steel round pipe, and a portion of the holding material 3 is caulked to prevent the pen shaft 4 from coming off. By caulking, a lower caulking portion 9 in which substantially the entire outer periphery on the tip end side of the pen shaft 4 is recessed is formed. The pen shaft 4 may be a metal other than stainless steel.

  The tip of the pen core 2 that further protrudes from the holding material 3 is covered with a pen tip protection member 5 made of a conductive resin material. The nib protection member 5 is insert-molded together with the pen core 2, for example, and is prevented from coming off by flowing a resin material so as to surround the periphery of the bent portion 2a during the insert molding. In the present embodiment, the pen point protecting member 5 extends to the central portion of the pen core 2, but does not need to extend to the central portion, and may be long enough to cover at least the bent portion 2a. The pen point protection member 5 may be any conductive material that has a lower hardness than a metal and does not damage the touch panel 22, such as a synthetic resin, elastomer, rubber, or the like that contains a large amount of conductive powder such as carbon. That is, the surface of the touch panel 22 is often made of glass, acrylic (hardness equivalent to aluminum), or a film for preventing scattering. The material is not particularly limited.

  A space between the nib protection member 5 and the tip of the pen shaft 4 is covered with a nib reinforcing material 6 made of an insulating material. The nib reinforcing member 6 is made of, for example, ABS resin, and has a truncated cone shape with an outer diameter gradually decreasing toward the tip and having a through hole 6a in the center. As long as the nib reinforcing material 6 has an insulating property, the material is not particularly limited, and may be an appropriately soft material such as elastomer or rubber.

  A pen head 7 made of, for example, an elastomer is fixed to the base end side of the pen shaft 4 by caulking. By caulking, an upper caulking portion 10 in which substantially the entire outer periphery of the base end side of the pen shaft 4 is recessed is formed. Note that a protrusion 27 may be provided on the pen housing portion 26 so as to correspond to the upper caulking portion 10. The pen head 7 is preferably made of a weather-resistant material that can be easily colored in accordance with the color of the housing 23. The shape of the pen head 7 has an exposed portion 7 a having a shape matching the curved side surface shape of the housing 23. Then, for example, the stylus pen 1 is inserted into the pen housing portion 26 from the distal end side thereof, and the outer periphery thereof is fitted into the locking portion 28, and the lower caulking portion 9 is fitted into the projection portion 27 of the pen housing portion 26. As a result, the stylus pen 1 is prevented from dropping while a clicking feeling is obtained. When the stylus pen 1 is completely accommodated in the pen accommodating portion 26, the surface height of the exposed portion 7a exposed from the lower opening 24a of the rear cover 24 is configured to be the same as the periphery of the housing 3. Yes. In FIG. 4, the telescopic antenna 29 can be seen from the upper opening 24b of the rear cover 24 above the exposed portion 7a. If the exposed portion of the telescopic antenna 29 and the shape of the exposed portion 7a are the same, It looks good as a target shape.

  As an assembly procedure of the stylus pen 1, for example, the pen tip protection member 5 is insert-molded into the pen core 2, and the proximal end side of the pen core 2 is inserted into the through hole 6 a of the pen tip reinforcement member 6. The holding material 3 is inserted into the base end side and caulked, then the pen shaft 4 is inserted, and the lower caulking portion 9 is formed by caulking the portion of the holding material 3. Further, after the pen head 7 is inserted into the base end side of the pen shaft 4, the upper caulking portion 10 is formed and fixed by caulking.

  In this way, the pen core 2 is made of metal and the tip of the pen core 2 is covered with the pen tip protection member 5 made of a conductive resin material to prevent the touch panel 22 from being damaged while preventing the resistance value from increasing. Can do.

  Moreover, since the nib protection member 5 is insert-molded into the bent portion 2a of the metal rod, the pen tip protection member 5 is not only caught and prevented from being detached, but also the projection of the portion closest to the touch panel 22 at the tip portion. The area increases and it is easy to detect from the touch panel 22. Further, since only bending is required, a complicated process such as forging is unnecessary, which is advantageous in terms of manufacturing cost.

  Further, since the pen core 2 is held by the metal holding member 3 and fixed to the metal pen shaft 4, the strength is ensured while preventing the resistance value from increasing.

  Furthermore, since the nib reinforcing material 6 in the vicinity of the nib is made of an insulating material, the detection displacement of the touch panel 22 that the touch panel 22 reacts with other than the nib when the nib is tilted is reduced.

  Therefore, according to the stylus pen 1 according to the present embodiment, the conductive holding material 3 that holds the metal pen core 2 is covered with the conductive pen shaft 4, and the pen tip is prevented from being detached by the conductive pen tip protection member 5. Since it is covered with the state and reinforced with the insulating pen point reinforcing material 6, even the thin pen shaft 4 can be made highly accurate without damaging the surface of the touch panel 22.

The retaining portion is configured by a folded U-shaped portion 102a of the bent metal wire. Also in this case, the pen core 102 is insert-molded by the pen tip protection member 5, so that the pen tip protection member 5 that flows between the U-shaped folded portions 102 a is caught and reliably prevented from coming off. In addition, the projected area of the folded portion 102a increases, and detection from the touch panel 22 becomes easier. Moreover, since the pen core 102 is composed of two wires, it can be used even if one of them is disconnected.
