Description

本発明は、携帯電話、携帯端末、電子機器などの静電容量方式タッチパネル用タッチペンに関するものである。   The present invention relates to a touch pen for a capacitive touch panel such as a mobile phone, a mobile terminal, and an electronic device.

近年、携帯電話、音楽プレーヤ、ゲーム機、携帯端末、情報端末、パソコン、テレビなどの電子機器に、指で触れることにより、座標入力、キーメニュー選択操作、表示画像の切換え、スクロール、回転、拡大、縮小の指示ができる専用の入力用タッチパネル、タッチパッドもしくはディスプレイと一体化されたタッチスクリーンが採用されている。   In recent years, by touching electronic devices such as mobile phones, music players, game consoles, mobile terminals, information terminals, personal computers, and televisions, you can input coordinates, select key menus, switch display images, scroll, rotate, and zoom. A touch screen integrated with a dedicated input touch panel, a touch pad, or a display capable of instructing reduction is employed.

また、指、マウス、トラックボールなどよりもより細かく正確な入力選択操作、文字、サイン、イラストなどの筆記入力に適し、またディスプレイと一体化されたタッチスクリーンの画面を指紋で汚すことの少ないタッチペンもゲーム機、携帯端末、情報端末では広く使われている。   It is also suitable for finer and more accurate input selection operations than letters, mice, trackballs, etc., and for writing input of characters, signs, illustrations, etc., and a touch pen that does not smudge the touch screen screen integrated with the display with fingerprints Are widely used in game consoles, portable terminals, and information terminals.

一方、携帯電話、携帯端末、音楽プレーヤではディスプレイと一体化されたタッチスクリーン上の表示画像との連係動作による指での軽い入力圧力操作が好まれるため、タッチパネルとして主要な方式である感圧抵抗膜方式、電磁誘導方式、静電容量方式の中でも特に静電容量方式が多く採用されている。   On the other hand, in cellular phones, portable terminals, and music players, light input pressure operation with a finger is preferred due to the coordinated operation with the display image on the touch screen integrated with the display. Of the membrane system, electromagnetic induction system, and electrostatic capacity system, the electrostatic capacity system is often used.

静電容量方式のタッチパネルにおいては指と同様の軽い入力圧力でより細かく正確な入力操作、文字、サイン、イラストなどの筆記入力に適したタッチペンが利用されている。   Capacitive touch panels use touch pens that are suitable for finer and more accurate input operations and writing input such as letters, signs, and illustrations with the same light input pressure as a finger.

静電容量方式ではタッチパネルに対して使用者の指と同様の導電性を持つ材料で作られたタッチペンとして、使用者の手に把持される導電性材料製のペン本体部とその本体と電気的に導通された導電性材料製のペン芯先端部を備えたものが提案されている。ペン芯先端部はゴムに導電性のカーボンの粉末またはカーボンの繊維または金属の粉末または金属の繊維などを配合した複合材料を用いた例がある。   In the capacitive method, a touch pen made of a material that has the same conductivity as the user's finger with respect to the touch panel, and a pen body made of a conductive material that is gripped by the user's hand and the body There has been proposed one provided with a pen core tip portion made of a conductive material that is electrically connected to. For example, the tip of the pen core may be made of a composite material in which conductive carbon powder or carbon fiber, metal powder or metal fiber is blended with rubber.

従来、この種のタッチペンとしては、例えば、特許文献１に記載されているようなものがあった。
図７および図８は前記特許文献１に記載された従来の静電容量方式タッチパネル用タッチペンを示している。 Conventionally, as this type of touch pen, for example, there is one described in Patent Document 1.
7 and 8 show a conventional capacitive touch panel touch pen described in Patent Document 1. FIG.

図７および図８において、ペン本体部１およびペン芯先端部２は導電性材料で作られており、ペン芯先端部２はゴムに導電性カーボンの粉末または金属の粉末または金属の繊維などを配合した複合材料より構成されている。   7 and 8, the pen main body 1 and the pen core tip 2 are made of a conductive material, and the pen core tip 2 is made of conductive carbon powder, metal powder, metal fiber or the like on rubber. It is composed of a blended composite material.

また、特許文献２に記載されているように、導電性材料製のペン芯先端部と電気的に導通する導通部を使用者の手に把持されるペン本体部の外周に備えるタッチペンの例がある。   In addition, as described in Patent Document 2, an example of a touch pen including a conductive portion that is electrically connected to a pen core tip portion made of a conductive material on the outer periphery of a pen body portion gripped by a user's hand is provided. is there.

また、特許文献３記載されているように、複数本の導電性繊維により筆形に形成したペン芯先端部を備えるタッチペンの例がある。   In addition, as described in Patent Document 3, there is an example of a touch pen including a pen core tip formed in a brush shape by a plurality of conductive fibers.

しかしながら、前記従来の構成では、静電容量方式タッチパネル用タッチペンは、ペン本体部またはペン本体部の外周部に導電部を備えなければならず、この導電部は、金属、導電性繊維、金属の粉末、金属の繊維、カーボンの粉末、カーボンの繊維を含んだゴムまたは樹脂を用いるため、そのペン本体部に対して、自由な外観の色、素材配置、デザインができない課題があった。
また、導電性材料製のペン本体部またはペン本体部の外周に備わる導通部が、電子機器の外部端子コネクタの金属端子、充電用コネクタの金属端子、電源プラグの金属端子、電源コンセントの金属端子などに不用意に接触してショート、電子機器の故障原因となる課題があった。 However, in the conventional configuration, the touch pen for a capacitive touch panel must include a conductive portion on the outer periphery of the pen body or the pen body, and the conductive portion is made of metal, conductive fiber, or metal. Since powder, metal fiber, carbon powder, rubber or resin containing carbon fiber is used, there is a problem that the color, material arrangement, and design of a free appearance cannot be performed on the pen body.
Also, the pen body part made of conductive material or the conduction part provided on the outer periphery of the pen body part is a metal terminal of an external terminal connector of an electronic device, a metal terminal of a charging connector, a metal terminal of a power plug, a metal terminal of a power outlet Inadvertently touching, etc., there was a problem that caused a short circuit and failure of electronic equipment.

本発明は、上述の問題点を解決するためになされたもので、自由な外観の色、素材配置、デザインの静電容量方式タッチパネル用タッチペンを実現するとともに、タッチペンの本体が電子機器の外部コネクタの金属端子、充電用コネクタの金属端子、電源プラグの金属端子、電源コンセントの金属端子などに不用意に接触してもショート、電子機器の故障原因とならない安全な静電容量方式タッチパネル用タッチペンを実現することを目的とする。   The present invention has been made to solve the above-described problems, and realizes a touch pen for a capacitive touch panel having a free appearance color, material arrangement, and design, and the main body of the touch pen is an external connector of an electronic device.

It aims to be realized.

前記従来の課題を解決するため、本発明の静電容量方式タッチパネル用タッチペンは、導電性材料製のペン芯先端部およびペン芯軸部と、ペン芯軸部の外周を覆う電気的な導通のない絶縁性材料製のペン本体部からなり、ペン芯軸部の外周に重ねて空隙なく絶縁性材料製のペン本体部においては、ペン本体部の全長の少なくとも使用者のタッチペンの持ち手の触れる範囲の内部は導電性材料製のペン芯軸部が占有する構成とする。   In order to solve the above-described conventional problems, the touch pen for a capacitive touch panel according to the present invention is an electrically conductive pen tip and a pen core shaft made of a conductive material, and an electrically conductive cover that covers the outer periphery of the pen core shaft. In the pen body part made of an insulating material, which is made of a non-insulating material pen body part and overlaps the outer periphery of the pen core shaft part and has no gap, the pen body part of the entire length of the pen body part touches at least the user's touch pen handle. The inside of the range is configured to be occupied by a pen core shaft made of a conductive material.

本発明のタッチペンのペン芯先端部を静電容量方式タッチパネルの表面に接触させると、タッチパネル内の検出電極とペン芯先端部とが第一の静電容量結合を行ない、更にペン芯先端部と電気的に導通するペン芯軸部が、その外周を覆う絶縁性材料製のペン本体部を挟んで、使用者のタッチペンの持ち手との間に第二の静電容量結合を行うことで、タッチペンのタッチパネルへの接触検出が行なわれる。   When the tip of the touch pen of the touch pen according to the present invention is brought into contact with the surface of the capacitive touch panel, the detection electrode in the touch panel and the tip of the pen lead perform first capacitive coupling. The pen core shaft portion that is electrically conductive sandwiches the pen body portion made of an insulating material that covers the outer periphery of the pen core shaft portion, and by performing the second capacitive coupling with the handle of the user's touch pen, Touch detection of the touch pen on the touch panel is performed.

ペン芯軸部の外周を覆うペン本体部の材質はその外観の色、素材配置、デザインを自由に行なうことが可能で絶縁耐電圧の高い合成樹脂などの安価で一般的な絶縁性材料を用い、タッチペンの本体が電子機器の外部コネクタの金属端子、充電用コネクタの金属端子、電源プラグの金属端子、電源コンセントの金属端子などに不用意に接触してもショート、電子機器の故障原因とならない安全な静電容量方式タッチパネル用タッチペンを実現できる。   The pen body material that covers the outer periphery of the pen core shaft can be freely designed in terms of color, material layout, and design, and uses inexpensive and general insulating materials such as synthetic resins with high dielectric strength. If the touch pen body is inadvertently contacted with the metal terminal of the external connector of the electronic device, the metal terminal of the charging connector, the metal terminal of the power plug, the metal terminal of the power outlet, etc., it will not cause a short circuit or malfunction of the electronic device. A safe touch pen for capacitive touch panel can be realized.

本発明によれば、自由な外観の色、素材配置、デザインの静電容量方式タッチパネル用タッチペンを実現するとともに、タッチペンの本体部が電子機器の外部コネクタの金属端子、充電用コネクタの金属端子、電源プラグの金属端子、電源コンセントの金属端子などに不用意に接触してもショート、電子機器の故障原因とならない静電容量方式タッチパネル用タッチペンを実現できる。   According to the present invention, a touch pen for a capacitive touch panel with a free appearance color, material arrangement, and design is realized, and the touch pen main body is a metal terminal of an external connector of an electronic device, a metal terminal of a charging connector, Capacitive touch panel touch pens that do not cause a short circuit or failure of electronic equipment even if they are inadvertently contacted with a metal terminal of a power plug or a metal terminal of a power outlet can be realized.

FIG. 6 is a cross-sectional view of a capacitive touch panel touch pen according to Embodiment 4 of the present invention. The description of the configuration that has already been described is omitted.
The outside of the pen core shaft portion 14 made of a conductive material is covered with a pen main body portion 11 made of an insulating material, and made of an insulating material housed in a hollow portion provided at the center of the pen core shaft portion 14 made of a conductive material. The pen main body expansion / contraction part 15 and the pen core expansion / contraction part 16 made of a conductive material in the pen main body expansion / contraction part 15, and the pen core expansion / contraction part 16 made of a conductive material is externally attached when the touch pen expands and contracts. The structure is not exposed to
When the touch pen is extended to a length that is easy to use during use, the pen core shaft expansion / contraction part 16 made of a conductive material is covered with the pen main body expansion / contraction part 15 made of an insulating material and is not exposed to the appearance. In addition to realizing a free appearance design, the touch pen is short-circuited even if it touches the metal terminal of the external connector of the electronic device, the metal terminal of the connector for charging, the metal terminal of the power plug, the metal terminal of the power outlet, etc. The cause of failure of electronic equipment can be reduced.
It has a spring 18 made of a conductive material for electrically connecting the pen core shaft portion 14 made of a conductive material and the pen core shaft extension / contraction portion 16 made of a conductive material.
When the touch pen expands and contracts, the spring 18 made of a conductive material always electrically connects the pen core shaft portion 14 made of a conductive material and the pen core shaft expandable portion 16 made of a conductive material.
The pen core tip portion 2 and the pen core shaft portion 14 may be relayed by a metal screw, a metal shaft, or a metal spring, in addition to a fitting or contact structure that is electrically conductive. The tip portion 2 and the pen core shaft portion 14 may be molded as an integral product with the same material.
Even when the touch pen is shortened to be compact when being carried and the touch pen is extended to a length that is easy to use, the pen core shaft portion 14 and the pen core shaft expansion / contraction portion 16 made of conductive material are exposed from the outer peripheral surface of the pen body portion 11. This eliminates the need for a free external design, and the stylus touches the metal terminal of the external connector of the electronic device, the metal terminal of the charging connector, the metal terminal of the power plug, the metal terminal of the power outlet, etc. However, it is possible to reduce the cause of short circuit and electronic device failure.
The spring 18 may have a function of assisting a user's force when the touch pen is extended or contracted.

本発明は例えば携帯電話、音楽プレーヤ、ゲーム機、携帯端末、情報端末、パソコン、テレビ、カーナビゲーションなどの電子機器の静電容量方式タッチパネル用タッチペンに利用可能である。   The present invention is applicable to a touch pen for a capacitive touch panel of an electronic device such as a mobile phone, a music player, a game machine, a mobile terminal, an information terminal, a personal computer, a TV, and a car navigation.
