(2) Inside of Input Touch Pen 5 FIG. 4 is a cross-sectional view corresponding to the input touch pen 5 shown in FIG.
As shown in FIG. 4, an electromagnetic induction refill 30 is accommodated in the shaft tube 10. Further, a resilient member 70 that urges the electromagnetic induction refill 30 toward the rear end side in the axial direction is accommodated inside the front shaft 12 of the shaft tube 10. The details of the electromagnetic induction refill 30 and the elastic member 70 will be described later.

先軸12は、その後端から先端にかけて先細となるテーパ形状に形成されている。また、先軸12の内部には、先軸12の内径が不連続に減じた部分であって、弾発部材70の先端が接触する段部12Aが形成されている。
後軸14の後端側には、ノック操作により電磁誘導リフィル30を軸方向に摺動させるノック機構20が装着されている。
The front shaft 12 is formed in a tapered shape that tapers from the rear end to the front end. Further, inside the front shaft 12, a step portion 12 </ b> A is formed in which the inner diameter of the front shaft 12 is discontinuously reduced and the tip of the elastic member 70 contacts.

<電磁誘導リフィル30>
図5は、本実施の形態に係る電磁誘導リフィル30の正面図(A)及び正面図に対応する断面図(B)である。
電磁誘導リフィル30は、電磁誘導方式による入力に用いられるものであって、例えば、以下の構成から成る。
<Electromagnetic induction refill 30>
FIG. 5 is a front view (A) and a sectional view (B) corresponding to the front view of the electromagnetic induction refill 30 according to the present embodiment.
The electromagnetic induction refill 30 is used for input by an electromagnetic induction method and has, for example, the following configuration.

電磁誘導リフィル30は、図5(A)に示すように、電磁誘導方式による入力に用いられるリフィル本体40と、リフィル本体40の一部を被覆する被覆部材60と、を備えている。
リフィル本体40は、図5(B)に示すように、その先端と後端とにそれぞれ開口部を有する収容筒41を備えており、この収容筒41の内部に種々の部材が収容され、また、収容筒41に種々の部材が装着されている。
As shown in FIG. 5A, the electromagnetic induction refill 30 includes a refill main body 40 used for input by an electromagnetic induction method, and a covering member 60 that covers a part of the refill main body 40.
As shown in FIG. 5 (B), the refill main body 40 includes an accommodating cylinder 41 having openings at the front and rear ends, and various members are accommodated in the accommodating cylinder 41. Various members are attached to the housing cylinder 41.

収容筒41の先端側には、棒状のフェライトコア42を内蔵した、合成樹脂製の先端継手43が装着されている。また、フェライトコア42の先端には、合成樹脂製であり、使用者によるノック操作に基づいて先端開口13(図1参照)から出没可能な接触先端44が装着されている。さらに、フェライトコア42の周囲には、先端継手43を挟んで電磁誘導コイル45が配設されている。   A tip joint 43 made of synthetic resin and incorporating a rod-shaped ferrite core 42 is attached to the tip side of the housing cylinder 41. Further, the tip of the ferrite core 42 is made of a synthetic resin, and a contact tip 44 that can protrude and retract from the tip opening 13 (see FIG. 1) based on a knocking operation by a user is mounted. Further, an electromagnetic induction coil 45 is disposed around the ferrite core 42 with a tip joint 43 interposed therebetween.

収容筒41の内部空間におけるフェライトコア42よりも後端側には、電磁誘導コイル45と電気的に接続された感圧センサ46とコンデンサ47とが収容されている。また、収容筒41の後端には、合成樹脂製の後端継手48が装着されている。   A pressure-sensitive sensor 46 and a capacitor 47 that are electrically connected to the electromagnetic induction coil 45 are accommodated on the rear end side of the ferrite core 42 in the internal space of the accommodating cylinder 41. Further, a synthetic resin rear end joint 48 is attached to the rear end of the housing cylinder 41.

後端継手48の後端には、リフィル本体40と被覆部材60との固定を介在する介在部49が装着されている。この介在部49の後端側は軸方向に沿って開口している。また、介在部49の開口部分には、リフィル尾栓50の先端部分が圧入され、これにより、介在部49とリフィル尾栓50とが接続されている。そして、リフィル尾栓50の後端部分は、被覆部材60に対して圧入されており、これにより、リフィル本体40とリフィル尾栓50とが固定される。なお、リフィル本体40とリフィル尾栓50とが固定された状態では、リフィル尾栓50の後端が被覆部材60の後端から露出している。   At the rear end of the rear end joint 48, an interposition part 49 for attaching the refill main body 40 and the covering member 60 is attached. The rear end side of the interposition part 49 is open along the axial direction. Further, the distal end portion of the refill tail plug 50 is press-fitted into the opening portion of the interposition portion 49, whereby the interposition portion 49 and the refill tail plug 50 are connected. And the rear-end part of the refill tail plug 50 is press-fitted with respect to the coating | coated member 60, and, thereby, the refill main body 40 and the refill tail plug 50 are fixed. When the refill body 40 and the refill tail plug 50 are fixed, the rear end of the refill tail plug 50 is exposed from the rear end of the covering member 60.

また、介在部49の周囲には、収容筒41を先端側に付勢するリターンスプリング51が装着されている。このリターンスプリング51は、接触先端44が押圧されることに伴い収容筒41が後端側へ移動する際に圧縮される。なお、電磁誘導リフィル30は軸筒10から着脱可能とされており、また、リフィル本体40は被覆部材60から着脱可能とされている。そのため、接触先端44が摩耗したり、内蔵する電子機器類が故障したりした際には、容易に新品と交換することができる。   A return spring 51 that urges the housing cylinder 41 toward the distal end side is mounted around the interposition part 49. The return spring 51 is compressed when the receiving cylinder 41 moves to the rear end side when the contact tip 44 is pressed. The electromagnetic induction refill 30 is detachable from the shaft tube 10, and the refill main body 40 is detachable from the covering member 60. For this reason, when the contact tip 44 is worn out or a built-in electronic device breaks down, it can be easily replaced with a new one.

<弾発部材70>
図6は、本実施の形態に係る弾発部材70の斜視図である。
図6に示すように、弾発部材70は、ばね形状、具体的には、コイルばね形状に形成されている。
<Bounce member 70>
FIG. 6 is a perspective view of a resilient member 70 according to the present embodiment.
As shown in FIG. 6, the elastic member 70 is formed in a spring shape, specifically, a coil spring shape.

また、弾発部材70は、銅線がコイル形状に巻かれて形成された電磁誘導コイル45よりも軟質である絶縁性材料で形成されており、本実施の形態では熱可塑性樹脂で形成されている。本実施の形態における絶縁性材料は、抵抗値が1010Ω・cmよりも大きい材料とされている。なお、上記の「軟質」とは、例えば、弾発部材70と電磁誘導コイル45との各々を構成する材料の曲げ弾性率について、前者が後者より低いこととして定義することができる。 The elastic member 70 is made of an insulating material that is softer than the electromagnetic induction coil 45 formed by winding a copper wire in a coil shape. In this embodiment, the elastic member 70 is made of a thermoplastic resin. Yes. The insulating material in this embodiment is a material having a resistance value larger than 10 10 Ω · cm. In addition, said "soft" can be defined as the former being lower than the latter about the bending elastic modulus of the material which comprises each of the elastic member 70 and the electromagnetic induction coil 45, for example.

そして、本実施の形態では、弾発部材70を形成する熱可塑性樹脂として、ポリエーテルエーテルケトン(PEEK)を用いている。なお、弾発部材70を形成する熱可塑性樹脂は、ポリエーテルエーテルケトン(PEEK)が好適であるが、それに限らず、例えば、ポリカーボネート、ポリアセタール、アクリロニトリルスチレン、等の合成樹脂を用いてもよい。   In this embodiment, polyether ether ketone (PEEK) is used as the thermoplastic resin forming the resilient member 70. The thermoplastic resin forming the elastic member 70 is preferably polyetheretherketone (PEEK), but is not limited thereto, and synthetic resins such as polycarbonate, polyacetal, acrylonitrile styrene, and the like may be used.

ここで、弾発部材70は、先軸12の内部に収容された状態では、電磁誘導コイル45の外周に配設されるとともに、その先端が段部12Aに接触し、その後端が被覆部材60の先端の縁部分である先端縁部60A(図4及び図5参照)に接触している。これにより、弾発部材70は、使用者によるノック部材22のノック操作に伴い、段部12Aと先端縁部60Aとの間で圧縮する。   Here, the elastic member 70 is disposed on the outer periphery of the electromagnetic induction coil 45 in the state of being accommodated in the front shaft 12, and the tip thereof is in contact with the stepped portion 12 </ b> A, and the rear end thereof is the covering member 60. 60A (refer to FIG. 4 and FIG. 5) is in contact with the leading edge portion 60A (see FIG. 4 and FIG. 5). Thereby, the elastic member 70 is compressed between the step portion 12A and the tip edge portion 60A in accordance with the knocking operation of the knock member 22 by the user.

(3)作用
次に、本実施の形態の作用、具体的には、電磁誘導リフィル30により入力装置(例:電磁誘導タブレット)に情報が入力される流れについて説明する。なお、入力装置は、電磁誘導リフィル30による入力が行われる入力面が設けられており、その入力面の下面には、特定の周波数の電磁波を発生する位置検出装置が設けられている。
(3) Operation Next, the operation of the present embodiment, specifically, the flow in which information is input to the input device (eg, electromagnetic induction tablet) by the electromagnetic induction refill 30 will be described. The input device is provided with an input surface on which input by the electromagnetic induction refill 30 is performed, and a position detection device that generates an electromagnetic wave having a specific frequency is provided on the lower surface of the input surface.

まず、電磁誘導リフィル30による入力を行うためには、接触先端44が軸筒10内に没入した没入状態(図7(A)参照)から、接触先端44を軸筒10から突出させた突出状態(図4及び図7(B)参照)へと変移させる必要がある。   First, in order to perform input by the electromagnetic induction refill 30, a protruding state in which the contact tip 44 protrudes from the shaft tube 10 from a immersed state in which the contact tip 44 is immersed in the shaft tube 10 (see FIG. 7A). It is necessary to shift to (see FIGS. 4 and 7B).

図7(A)は、本実施の形態に係る入力タッチペン5の没入状態を示している。この没入状態では、弾発部材70が電磁誘導リフィル30を後端側へ付勢しており、接触先端44が軸筒10内に没入している。そして、没入状態において、使用者によるノック部材22のノック操作が行われると、押圧部材24の先端縁部24Aによりリフィル尾栓50が先端側に押圧される。このノック操作により、弾発部材70が段部12Aと先端縁部60Aとの間で圧縮され、電磁誘導リフィル30が先端側へ移動し、突出状態へと変移する。なお、図7(B)は、突出状態のうち、接触先端44を最大限軸筒10から突出させた最大突出状態を示している。   FIG. 7A shows an immersion state of the input touch pen 5 according to the present embodiment. In this immersed state, the elastic member 70 biases the electromagnetic induction refill 30 toward the rear end side, and the contact tip 44 is immersed in the shaft tube 10. When the knocking operation of the knocking member 22 is performed by the user in the immersion state, the refill tail plug 50 is pressed toward the distal end side by the distal end edge portion 24 </ b> A of the pressing member 24. By this knocking operation, the elastic member 70 is compressed between the stepped portion 12A and the tip edge portion 60A, and the electromagnetic induction refill 30 moves to the tip side and changes to a protruding state. FIG. 7B shows a maximum protruding state in which the contact tip 44 protrudes from the shaft cylinder 10 to the maximum in the protruding state.

ここで、没入状態における弾発部材70の全長はL1であり(図7(A)参照)、最大突出状態における弾発部材70の全長(密着長さ)はL2である(図7(B)参照)。そのため、本実施の形態における電磁誘導リフィル30は、L1とL2との差であるL3だけ(L1−L2=L3)、軸方向に移動可能となっている。なお、最大突出状態において、使用者がノック部材22から指を離した場合には、電磁誘導リフィル30が後端側へ若干移動し、図4に示す突出状態へと変移する。
また、図7(B)に示す最大突出状態である場合、電磁誘導コイル45は、先軸12の先端開口13の内部の段に当接しないため、電磁誘導リフィル30としての機能を損なうことを防ぐことができる。
Here, the total length of the elastic member 70 in the immersion state is L1 (see FIG. 7A), and the total length (contact length) of the elastic member 70 in the maximum protruding state is L2 (FIG. 7B). reference). Therefore, the electromagnetic induction refill 30 in the present embodiment can move in the axial direction only by L3 (L1−L2 = L3) which is the difference between L1 and L2. When the user lifts his / her finger from the knock member 22 in the maximum projecting state, the electromagnetic induction refill 30 slightly moves to the rear end side and changes to the projecting state shown in FIG.
7B, since the electromagnetic induction coil 45 does not contact the step inside the tip opening 13 of the front shaft 12, the function as the electromagnetic induction refill 30 is impaired. Can be prevented.

上記の入力装置が有する位置検出装置には、電磁誘導リフィル30に電磁エネルギーを送信するためのコイルが複数設けられている。一方、電磁誘導リフィル30には、送信信号の周波数に応じた共振周波数を有する共振回路(図示せず)が設けられている。この位置検出装置のコイルと電磁誘導リフィル30の共振回路(図示せず)の電磁誘導作用により電磁誘導リフィル30は電磁エネルギーを蓄えることができる。   The position detection device included in the input device is provided with a plurality of coils for transmitting electromagnetic energy to the electromagnetic induction refill 30. On the other hand, the electromagnetic induction refill 30 is provided with a resonance circuit (not shown) having a resonance frequency corresponding to the frequency of the transmission signal. The electromagnetic induction refill 30 can store electromagnetic energy by the electromagnetic induction action of the resonance circuit (not shown) of the coil of the position detection device and the electromagnetic induction refill 30.

そして、電磁誘導リフィル30は、共振回路(図示せず)に蓄えた電磁エネルギーを位置検出装置に帰還させる。位置検出装置は、この電磁誘導リフィル30からの電磁エネルギーを検出する。具体的には、位置検出装置は、送信信号を供給したコイルの位置と、電磁誘導リフィル30の共振回路(図示せず)からの電磁エネルギーを検出したコイルの位置とにより、電磁誘導リフィル30が指示する座標値を検出する。
また、突出状態において、電磁誘導リフィル30の接触先端44が押圧されると、コンデンサ47が押圧されて静電容量が増加する。これにより共振周波数がわずかに低くなる。そして、位置検出装置が電磁誘導リフィル30の共振周波数の変化を検出することで、電磁誘導リフィル30の接触を検出する。これにより文字等を描くことができる。
The electromagnetic induction refill 30 returns the electromagnetic energy stored in the resonance circuit (not shown) to the position detection device. The position detection device detects electromagnetic energy from the electromagnetic induction refill 30. Specifically, the position detection device determines whether the electromagnetic induction refill 30 is based on the position of the coil that supplied the transmission signal and the position of the coil that detected the electromagnetic energy from the resonance circuit (not shown) of the electromagnetic induction refill 30. The designated coordinate value is detected.
In the protruding state, when the contact tip 44 of the electromagnetic induction refill 30 is pressed, the capacitor 47 is pressed and the capacitance increases. This slightly reduces the resonant frequency. The position detection device detects a change in the resonance frequency of the electromagnetic induction refill 30 to detect contact of the electromagnetic induction refill 30. Thereby, a character etc. can be drawn.
