Abstract
Description
また特許文献2には、コンピューターのタッチパネルに接触させて装置に情報入力を行うためのタッチペンであって、指に装着が可能な治具と、その治具に取り付けられたペン先部とを備えるものが開示されている。
一方、例えばスタイラスペンなどのペン方式の入力デバイスは、紛失しやすく、紛失した場合、タッチパネルへの入力の手段を失うことがある。さらに、これらペン方式の入力デバイスは、タッチパネルへの接触部分がボールペンなどと比べると大きく、タッチパネル上で入力デバイスの指す位置が正確にわかり難い。
上記の問題に鑑み、本発明の目的は、ユーザが指の摩滅感を感じにくくなると共に、タッチパネル上での入力デバイスの指す位置が正確にわかりやすく、タッチパネルが検出する位置の精度を向上することができ、さらに紛失しても入力の手段を失いにくい静電容量式のタッチパネル用の入力デバイス等を提供することである。
このとき、入力デバイスの少なくとも接触面は光透過性であり、好ましくは透明である。
(1)入力デバイスの少なくとも一部に設けられる粘着層を更に備え、入力デバイスを粘着層を介して積層させること
(2)入力デバイスを平面状に結合させること
(3)入力デバイスを筒状の形状とし、筒状の形状の入力デバイスを積層させること
以下、添付図面を参照して、本発明の実施の形態について詳細に説明する。
図1(a)~(b)は、本実施の形態が適用される入力デバイスの一例について説明した図である。
入力デバイス10は、静電容量式(静電容量方式、静電容量結合方式)のタッチパネルに接触させることで、このタッチパネル上の位置を入力するための入力デバイスである。ここで図1(a)は、入力デバイス10の全体を説明した斜視図であり、図1(b)は、図1(a)のIb-Ib断面図である。
図1(a)~(b)に示すように入力デバイス10は、可撓性を有する絶縁層11と、絶縁層11に積層して形成される導電層12と、導電層12上の一部に設けられる粘着層13とを備える。そして絶縁層11および導電層12は、一体として平面状の六角形をなす。
図2(a)~(b)は、実際に入力デバイス10をタッチパネル40に接触させた場合の状態を説明した図である。ここで図2(a)は、入力デバイス10をタッチパネル40に接触させた場合の状態を上方向から見た図である。また図2(b)は、入力デバイス10をタッチパネル40に接触させた場合の状態を横方向から見た図である。
図2(b)に示すように本実施の形態の入力デバイス10をタッチパネル40に接触させた場合、入力デバイス10の先端部14から概ね一定の長さの部分で屈曲し、所定の面積を有する接触面を形成する。なお図2(a)および図(b)では、入力デバイス10の接触面の範囲を点線で図示している。つまり図2(a)に示すように、入力デバイス10の先端部14から屈曲部までの三角形の部分が接触面である。そのため本実施の形態の入力デバイス10の場合、スタイラスペン等に比較して、タッチパネル40との接触する面積は大きくなりやすい。そのためタッチパネル40上での入力デバイス10の入力位置を視認しにくいときがある。
また、接触面は、半透明でもよいが、透明である方が、接触面下のタッチパネル40の画像が分かりやすく好ましい。
このような機能を発揮するため粘着層13は、感圧接着剤からなることが好ましい。即ち、接着箇所を張り合わせた瞬間に、接着が終了することが好ましい。また支持体に入力デバイス10を接着して固定する場合、支持体と入力デバイス10との接着は、強固である必要はなく、入力デバイス10を支持体から簡単に離脱させることができる方が、むしろ好ましい。本実施の形態では、入力デバイス10の六角形状の1つの辺に沿った位置とその辺に対向する辺に沿った位置の2箇所に粘着層13を配している。
図3(a)~(c)は、入力位置を表す図形の例について説明した図である。
ここで図3(a)は、この図形51として十字形状のものを示している。この場合は、十字の中心部が入力位置であることを意味する。また図3(b)は、この図形51として円形状のものを示している。この場合は円の内部が入力位置であることを意味する。更に図3(c)は、この図形51として矢印形状のものを示している。この場合は、矢印の先端部が入力位置であることを意味する。
このような図形51を入力デバイス10の接触面に描くことで、ユーザが入力デバイス10によるタッチパネル40への入力位置を更に視認しやすくなる。実際には、詳しくは後述するが、印刷等により絶縁層11および導電層12の少なくとも一方に図形51を描く。
また本実施の形態では、絶縁層11および導電層12の二層構造にすることで、入力デバイス10を構成する。これが絶縁層11のみであると、タッチパネルと人体との間に、微弱電流を流すことが困難となり、入力デバイスとして機能しない。また導電層12のみであると、導電層12を金属で形成した場合には、上述の通り、先端部14において点接触となりやすく接触不良が生じやすい。一方、本実施の形態の入力デバイス10では、絶縁層11は可撓性を有する樹脂シート等からなるため、先端部14において弾性変形し、湾曲してタッチパネルに接触する。このため面接触となりやすく、微弱電流をより流しやすくすることができる。
更に近年のタッチパネルは、複数の接触点を検知することができるものが多い。つまりいわゆるマルチタッチが可能となっており、これを利用してタッチパネルに対し予め定められた動作を行なうことで、例えば、画面の拡大や縮小などの種々の機能を実現させることができる。しかしながら入力デバイスとしてスタイラスペン等を使用した場合、タッチパネルの複数の箇所を同時にタッチすることは、困難である。一方、本実施の形態の入力デバイス10では、複数の指に入力デバイス10を装着することで、タッチパネルの複数の箇所を同時にタッチすることは容易である。
例えば、後述する入力デバイス10の集合体は、持ち運びは容易であり、必要なときに必要枚数を取り出してペンや指に装着して使用すればよい。使用済みの入力デバイス10は廃棄してもよい。
あるいは、使用したい場所にこの入力デバイス10を予め装備することで、ユーザが入力デバイス10を持ち歩く必要性が低くなる。また紛失しても代わりの入力デバイス10を用意することはスタイラスペン等に比較してより容易である。
更に本実施の形態の入力デバイス10は、絶縁層11として樹脂シートを用いた場合、印刷が可能である。即ち、入力デバイス10に、その指示位置を示す図形51を印刷できる。また、入力デバイス10の商品名や使用方法、あるいは種々の模様などを印刷できるため意匠として優れたものを作製しやすい。
また粘着層13は、個々の支持体の形状に合わせるためにユーザが筒状の入力デバイス10の形状を自由に設定できるという点では、設けた方がより好ましい。ただし入力デバイス10を予め筒状の形状とした状態で、流通させる場合も考えられる。この場合は、粘着層13を設けず、圧着等により接着し筒状の形状を維持させる方式も考えられる。この場合粘着層13は、必ずしも必要とはなくなる。
次に上述した入力デバイス10の具体的な使用形態について説明を行なう。
ここで図4(a)は、入力デバイス10の使用形態の第1の例を説明した図である。
図4(a)では、図1で示した入力デバイス10を筆記具20の形状に合わせて巻回させることで筒状の形状とした場合を示している。なおここではこの筒状の形態とした入力デバイス10を、区別のため便宜上入力デバイス10aと呼ぶ。この入力デバイス10aは、入力デバイス10を絶縁層11を外側とし、導電層12を内側として巻回させ、そして入力デバイス10の端部に配された粘着層13により接着して固定を行なうことにより筒状の形状を維持している。また入力デバイス10aは、筆記具20を先端部14に対向する位置にある先端部15の側から挿入し、筆記具20に装着した状態で使用する。
そしてタッチパネルを使用するユーザは、筆記具20に装着した入力デバイス10aを把持し、入力デバイス10aの先端部14をタッチパネルに接触させることで、タッチパネルに情報の入力を行なうことができる。この際、入力デバイス10aの少なくとも一部は、筆記具20を把持する手に接触していることが好ましい。
この場合、筆記具20は、ボールペン等の通常の筆記具でよい。そのためこの形態の場合、ユーザは、使い慣れた筆記具、または手近にある筆記具を使用してタッチパネルへの情報の入力を行なうことができる。この場合、タッチパネルへの入力と通常の筆記とを両方できるデバイスが得られる。
図4(b)では、図4(a)で示した入力デバイス10aを、図4(a)におけるIVb-IVbにおいて切断したものである。ここでは、この入力デバイス10を、区別のため便宜上入力デバイス10bと呼ぶ。入力デバイス10bは、指30を切断部の側から挿入し、指30に装着した状態で使用する。なお本実施の形態では、入力デバイス10bは、上述の通り切断部から先端部14にかけて絞り形状となるようにしている。そのため指30は、先端部14の方へは、貫通することができない。これにより入力デバイス10bを安定して筆記具20に装着することができる。更に粘着層13を導電層12の全面に設けておけば、この粘着層13と指30とが接着することで固定され、更に安定させることが可能である。
図4(c)では、図4(b)で示した入力デバイス10bを、図4(b)におけるIVc-IVcにおいて更に切断したものである。ここでは、この入力デバイス10を、区別のため便宜上入力デバイス10cと呼ぶ。入力デバイス10cは、指30全体を巻回するだけの幅はなく、指30の一部に接触して装着した状態で使用する。この場合、粘着層13により入力デバイス10cと指30とは、接着され固定されている。
また入力デバイス10a,10b,10cは、図1に示した入力デバイス10を絶縁層11を外側とし、導電層12を内側として巻回させることで作製したが、絶縁層11を内側とし、導電層12を外側として巻回させることで作製してもよい。
次に入力デバイス10を集合させた集合体について説明を行なう。
ここで図5(a)は、入力デバイス10の集合体の第1の例を説明した図である。
図5(a)に示した集合体100は、入力デバイス10をその厚み方向に積層させたものである。そして入力デバイス10を粘着層13を介して積層させることで集合体100としている。このような形態とすることで、入力デバイス10を流通させる場合において、集合体100としてまとめた形で流通させることができる。そして入力デバイス10を使用するユーザは、集合体100から1枚ずつ入力デバイス10をはぎ取り、支持体である筆記具20や指30に装着することで入力デバイス10を使用することができる。
図5(b)に示した集合体200は、台形状とした入力デバイス10を平面状に結合させることで集合体200としている。本実施の形態では、各入力デバイス10の間は、ミシン目となっており、これにより各入力デバイス10は結合している。そして入力デバイス10を使用するユーザは、集合体200からミシン目の部分を破ることで入力デバイス10を分離し、支持体である筆記具20や指30に装着することで入力デバイス10を使用することができる。
本実施の形態では、各入力デバイス10の向きを互いに逆にして結合させることで、集合体200をテープ状とすることができる。そしてこのテープ状の集合体200を巻き取る形態で、集合体200を流通させることができる。
図5(c)に示した集合体300は、筒状の形状の入力デバイス10bを積層させることで集合体300としている。このような形態とすることで入力デバイス10bを使用するユーザは、入力デバイス10bを集合体300から1つずつ取り外し、支持体である筆記具20や指30に装着することで入力デバイス10bを使用することができる。またこの形態では、支持体である筆記具20や指30に装着する際に巻回させる必要はない。そのためユーザは、即座に入力デバイス10bを使用することができる。
