【発明の属する技術分野】
本発明は、液晶表示部を有する情報端末装置に関し、特に液晶表示部に対する防塵対策を施した情報端末装置に関する。
【0002】
【従来の技術】
図7は、従来の情報端末装置の液晶表示部の断面の構成を示す断面図である。近年、携帯電話機等の情報端末装置は、小型化しているが、反面、液晶表示部にいたっては大型化が進んでおり、液晶表示部が大型化することによって、塵埃等のゴミが目立ち、外観的な品質を損なうため、防塵対策として液晶表示部の空間と装置内部との間を密閉することが重要な要素の一つとなっている。
【0003】
従来、防塵対策として、図7に示すように、通常ケース1aの内側と液晶表示器5の間に防塵クッション9を設けるという手法が一般的に採用されている。
【0004】
【発明が解決しようとする課題】
しかしながら、従来技術では、防塵クッションが必ず必要となっているため、貼付け工数および部品増加につながり、コストが高くなると共に組立て工程が増加してしまうという問題点があった。
【0005】
本発明は斯かる問題点を鑑みてなされたものであり、その目的とするところは、防塵クッションを使用することなく防塵を実現でき、コストを低減できるとともに組立て工程を簡略化することができる情報端末装置を提供する点にある。
【0006】
【課題を解決するための手段】
本発明は上記課題を解決すべく、以下に掲げる構成とした。
請求項1記載の発明の要旨は、ケースの液晶表示部用開口部のスクリーン貼付面とスクリーンとを両面テープにより接着させて液晶表示部が形成されている情報端末装置であって、液晶表示器を内包する固定部材と前記スクリーンとを前記両面テープにより接着させることを特徴とする情報端末装置に存する。
また請求項2記載の発明の要旨は、前記固定部材に接着用リブを形成させ、該接着用リブと前記スクリーンとを前記両面テープにより接着させることを特徴とする請求項1記載の情報端末装置に存する。
また請求項3記載の発明の要旨は、前記固定部材の前記接着用リブは、組立時に、前記スクリーン貼付面の内側に位置させると共に、前記スクリーン貼付面と同じ高さになるように形成されていることを特徴とする請求項2記載の情報端末装置に存する。
また請求項4記載の発明の要旨は、前記両面テープは、前記スクリーン貼付面より内側に広い形状であることを特徴とする請求項1乃至3のいずれかに記載の情報端末装置に存する。
また請求項5記載の発明の要旨は、組立時に、前記固定部材の前記接着用リブの内側に位置する防塵用リブを前記スクリーンの裏側に形成させることを特徴とする請求項乃至4のいずれかに記載の情報端末装置に存する。
また請求項6記載の発明の要旨は、前記固定部材の前記接着用リブに、前記スクリーンの前記防塵用リブの水平面に対向する水平対向部及び前記防塵用リブの外側鉛直面に対向する鉛直対向部が形成されていることを特徴とする請求項5記載の情報端末装置に存する。
ここで、本発明において「内側」「外側」とは、水平方向において、液晶表示部用開口部7の中心から見た「内側」「外側」をいう。
【0007】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて詳細に説明する。
【0008】
(第1の実施の形態)
図1は、本発明に係る情報端末装置の第1の実施の形態の構成を示す斜視図であり、図2は、図1に示す情報端末装置を分解した構成を示す爆発図であり、図3は、図2に示す固定部材(LCDフレーム)の構成を示す斜視図および断面図であり、図4は、図1に示す情報端末装置の液晶表示部の断面の構成を示す断面図である。
【0009】
図1および図2を参照すると、第1の実施の形態は、液晶表示部が設けられているケース1aとカバー1bとにより本体が形成され、ケース1aとカバー1bとにより形成された本体内に液晶表示器(LCD)5が固定部材(LCDフレーム)6を介してプリント基板2に取付けられ、スクリーン3が両面テープ4によってケース1aの液晶表示部用開口部7の外周に形成されているスクリーン貼付面8に貼付されている。
【0010】
固定部材(LCDフレーム)6は、図3に示すように、液晶表示器(LCD)5を内包する空間を有し、ケース1aの液晶表示部用開口部7の内側にはめ込まれるリブ6aが設けられている。
【0011】
リブ6aは、組立て時に、ケース1aのスクリーン貼付面8と同じ高さになるように形成されており、貼付されるスクリーン3の裏面まで達する事で、スクリーン3を液晶表示部用開口部7に接着させる両面テープ4に接着可能となり、スクリーン3との密閉性を保持する役目を果たす。
【0012】
図4を参照すると、固定部材(LCDフレーム)6のリブ6aの先端が、スクリーン3をケース1aに接着させる両面テープ4の裏面まで達する寸法となっていて、固定部材(LCDフレーム)6の周囲を両面テープ4により接着されたスクリーン3で覆う形となる。なお、両面テープ4は、リブ6aと接着する事を考えて、スクリーン貼付面8よりも内側に広くなっている。
【0013】
従って、液晶表示器(LCD)5を内包する固定部材(LCDフレーム)6がスクリーン3に密着することで液晶表示器(LCD)5の周囲を密閉し、防塵クッション等を追加する事無く、塵埃等のまわり込みを押さえる効果が得られる。
【0014】
しかも、本実施例では、もともとスクリーン3をケース1aに貼付させる両面テープ4を使用して防塵を実現し、防塵用のクッション等が不必要になるため、無用なコストアップを押さえられるという効果も得られる。
【0015】
以上説明したように、第1の実施の形態によれば、液晶表示器(LCD)5を内包する固定部材(LCDフレーム)6とスクリーン3とを両面テープ4を使用して密着させることで液晶表示器(LCD)5の周囲を密閉できるため、防塵クッションを使用することなく防塵を実現でき、コストを低減できるとともに組立て工程を簡略化することができるという効果を奏する。
【0016】
(第2の実施の形態)
図5は、本発明に係る情報端末装置の第2の実施の形態の液晶表示部の断面の構成を示す断面図である。
【0017】
第1の実施の形態では、固定部材(LCDフレーム)6のリブ6aにより防塵を行うように構成したが、第2の実施の形態では、更に防塵性を高めるためスクリーン3にリブ3aを形成してなる。
【0018】
図5を参照すると、第2の実施の形態は、組立時に、固定部材(LCDフレーム)6のリブ6aの内側に位置するように、スクリーン3の裏側にリブ3aが形成されている。なお、リブ3aは両面テープ4にかからない寸法とする。
【0019】
以上説明したように、第2の実施の形態によれば、第1の実施の形態による効果に加えて、液晶表示部の空間と装置内部との間に、固定部材(LCDフレーム)6のリブ6aとスクリーン3のリブ3aと2つのリブが塵埃等の侵入に対し遮蔽物として機能するため、塵埃等のまわり込みをさらに効率よく押さえることができるという効果を奏する。
【0020】
(第3の実施の形態)
図6は、本発明に係る情報端末装置の第3の実施の形態の液晶表示部の断面の構成を示す断面図である。
【0021】
図6を参照すると、第3の実施の形態は、固定部材(LCDフレーム)6に、組立て時に、ケース1aのスクリーン貼付面8と同じ高さになる部位と、スクリーン3に形成されたリブ3aと対向する部位とからなるリブ6bが形成されている。
【0022】
以上説明したように、第3の実施の形態によれば、第1の実施の形態による効果に加えて、装置内部へのゴミ等の到達距離が長くなるため、塵埃等のまわり込みをさらに効率よく押さえることができるという効果を奏する。
【0023】
なお、本発明が上記各実施形態に限定されず、本発明の技術思想の範囲内において、各実施形態は適宜変更され得ることは明らかである。また、上記構成部材の数、位置、形状等は上記実施の形態に限定されず、本発明を実施する上で好適な数、位置、形状等にすることができる。なお、各図において、同一構成要素には同一符号を付している。
