Abstract
Description
近年、タブレットタイプの携帯型電子機器の飛躍的な普及により、ユーザの価値観やライフスタイルが多様化し、デザインに求められる嗜好もよりスタイリッシュなものになっている。特に電子書籍専用端末のような、読書を行うための携帯型電子機器においては、ディスプレイ面側のデザインとして、書籍と同様の感覚で読書を行ううえで、狭ベゼル(狭額縁)の形状が、ユーザーから好まれている。さらに、端末の小型化にとっても狭ベゼルが望ましい。
共振パターンと、一部分に被膜除去部分を設けて外部導体を露出させた同軸ケーブルとを有し、被膜除去部分を金属シャーシの上端近傍において固定するPIFAタイプのアンテナと
を備える携帯端末である。
以下の説明は、下記の順序にしたがってなされる。
<1.一実施の形態>
<2.変形例>
「電子書籍専用端末の外観」
本開示の一実施の形態は、本開示を電子書籍専用端末に対して適用したものである。図1に示すように、電子書籍専用端末100は、タッチパネル101を有する。タッチパネル101は、光学式タッチパネル方式を採用したものである。タッチパネル101は、ディスプレイ上に設置されている。ディスプレイとしては、例えば6型電子ペーパーを使用することができる。電子ペーパーは、紙のような感覚で文字が見やすい利点を有し、電子書籍専用端末に使用して好適である。
図2に示すように、電子書籍専用端末は、複数の構成要素を積層した構造を有する。図3は、図2中の一点鎖線で示す線の断面図である。合成樹脂の成型品であるリアケース11が部品収納用凹部を有している。リアケース11の下面に対して、合成樹脂製のリアカバー12が積層されている。リアケース11の下端面には、上述したように、リセットボタン、マイクロUSB端子、電源ボタン等が設けられるが、図2では、これらの図示が省略されている。
本開示の一実施の形態は、WiFi(登録商標)(IEEE 802.11)の機能を有している。このための内蔵アンテナとしてPIFAタイプのアンテナが使用される。アンテナは、電子書籍専用端末100の上端の近傍の領域で、光学式タッチパネル101の領域の外側に設置される。この領域にアンテナを配置するのは、人の手とアンテナとの距離が小さいと、電波が人体により吸収され、利得の減少等の問題が生じる。電子書籍専用端末の場合、本体の下側半分を片手または両手で把持して使用することが普通である。したがって、本体の中央の領域および下側の領域には、アンテナを設けないことが好ましい。
1.本体の上部において、ディスプレイ用パネルとほぼ垂直になるように、PIFAタイプのアンテナを配置する構造を持つので、タブレットタイプの携帯用電子端末において、本体ディスプレイ面側で、狭ベゼル(狭額縁)のデザインを実現することが可能となり、ユーザのデザインに対する嗜好性を満足させることができる。図11Aは、本開示による端末装置例えば電子書籍専用端末の上部外観を示し、図11Bは、既存の電子書籍専用端末の上部外観を示す。本開示による電子書籍専用端末は、既存の電子書籍専用端末に比較してベゼルの幅をより狭いものとできる。
以上、本開示の実施の形態について具体的に説明したが、上述の各実施の形態に限定されるものではなく、本開示の技術的思想に基づく各種の変形が可能である。例えば、上述の実施の形態において挙げた構成、方法、工程、形状、材料および数値などはあくまでも例に過ぎず、必要に応じてこれと異なる構成、方法、工程、形状、材料および数値などを用いても良い。例えばWiFi(登録商標)以外の通信リンクを使用する場合のアンテナを使用する場合に対しても本開示を適用することができる。
