【発明の属する技術分野】
本発明は、携帯電話機の如く、画像撮影用のカメラを内蔵した携帯型通信端末機に関するものである。
【0002】
【従来の技術】
従来、画像撮影用のカメラを内蔵した携帯型通信端末機が知られている(例えば特許文献1参照)。
例えば折り畳み式携帯電話機においては、図2に示す如く、本体(1)と蓋体(2)がヒンジ機構(10)によって互いに開閉可能に連結されており、本体(1)の内面には、複数の操作キー(11)が配備されると共に、送話部(12)が設けられている。又、蓋体(2)の内面には、メインディスプレイ(21)が設置されると共に、受話部(22)が設けられている。
【0003】
蓋体(2)には、図10に示す如く、着信時に発光する着信報知LED(31)と、画像撮影用のCCDカメラ(32)と、画像表示用のサブディスプレイ(33)とが内蔵され、これらの光学部材を覆って化粧パネル(9)が設置されている。
化粧パネル(9)は、透明パネル本体(90)の両面に遮光膜(70)(80)を印刷してなり、該遮光膜(70)(80)の一部を開口せしめることによって、着信報知LED(31)からの光を前方へ放射せしめる着信報知窓部(91)と、前方からの映像光をCCDカメラ(32)に取り込む撮影窓部(92)と、サブディスプレイ(33)の映像光を表示する画像表示窓部(93)とが形成されている。

【0005】
【発明が解決しようとする課題】
しかしながら、図10に示す如く、着信報知LED(31)、CCDカメラ(32)及びサブディスプレイ(33)を同一平面上に配備した従来の携帯電話機においては、図中に矢印で示す様に、着信報知LED(31)やサブディスプレイ(33)から出射された光線が、前面遮光膜(80)と背面遮光膜(70)にて反射された後、CCDカメラ(32)へ入射することとなって、CCDカメラ(32)による撮影画像に悪影響を及ぼす問題があった。
【0006】
そこで本発明の目的は、画像撮影用カメラと、着信報知用発光素子や画像表示用ディスプレイ等の各種発光デバイスとを具えた携帯型通信端末機において、発光デバイスからカメラへ導かれる光を抑制して、撮影画像の品質の向上を図ることである。
【0007】
【課題を解決する為の手段】
本発明に係る携帯型通信端末機においては、ケースの内部に、画像撮影用のカメラと、該カメラによる画像撮影時に発光することとなる少なくとも1つの発光デバイスとが配備されると共に、前記ケースの表面には、前記カメラ及び発光デバイスをそれぞれ覆う複数の光透過性窓部が設けられている。
前記ケースは、前記発光デバイス及びカメラを覆って設置された化粧パネルを具えている。該化粧パネルは光透過性パネル本体を有して、該光透過性パネル本体の少なくとも片側に、前記複数の窓部を除く領域に拡がる遮光膜が形成されている。
又、前記化粧パネルには、光透過性パネル本体の少なくとも片面に密着して、前記複数の窓部を除く領域に拡がる光反射防止膜が形成されている。
具体的構成において、前記発光デバイスは、着信報知用の発光素子及び/又は画像表示用のディスプレイである。又、光反射防止膜は、例えば黒色又は灰色の塗料を用いた印刷によって形成することが出来る。
【0008】
上記本発明の携帯型通信端末機においては、発光デバイスから出射された光線が遮光膜にて反射された後、カメラへ向かって進んだとしても、その過程で大部分の光線が光反射防止膜へ入射して、光反射防止膜での反射が防止される。この結果、カメラへ入射する光の量は大幅に減少することになる。
【0009】
具体的構成においては、化粧パネルの光透過性パネル本体の背面に、前記光反射防止膜が介在している。
該具体的構成によれば、光反射防止膜の材質や製法に拘わらず、前面側の遮光膜に自由な着色を施すことが出来る。
【0010】
【発明の効果】
本発明に係る携帯型通信端末機によれば、発光デバイスからカメラへ入射する光の量が大幅に減少するので、高い画質の撮影画像を得ることが出来る。
【0011】
【発明の実施の形態】
以下、本発明を折り畳み式携帯電話機に実施した形態につき、図面に沿って具体的に説明する。
本発明に係る折り畳み式携帯電話機は、図1及び図2に示す如く、本体(1)と蓋体(2)をヒンジ機構(10)によって互いに開閉可能に連結して構成される。本体(1)の内面には、複数の操作キー(11)が配備されると共に、送話部(12)が設けられている。又、蓋体(2)の内面には、メインディスプレイ(21)が設置される共に、受話部(22)が設けられている。
【0012】
蓋体(2)は、図3及び図4に示す如く、下半ケース(3)と上半ケース(4)を具え、下半ケース(3)上には、着信時に発光する着信報知LED(31)と、画像撮影用のCCDカメラ(32)と、画像表示用のサブディスプレイ(33)とが、下半ケース(3)の中心線上に並べて配備されている。又、上半ケース(4)には、着信報知LED(31)、CCDカメラ(32)及びサブディスプレイ(33)を露出させるための3つの開口(41)(42)(43)が形成され、これら3つの開口(41)(42)(43)を覆って、化粧パネル(5)が設置されている。
【0013】
化粧パネル(5)は、図5及び図6に示す光透過性樹脂からなるパネル本体(50)を具え、該光透過性パネル本体(50)の前面には、図7に示す如く、着信報知窓部(51)、撮影窓部(52)及び画像表示窓部(53)を除く領域に、前面遮光膜(8)が形成されると共に、光透過性パネル本体(50)の背面には、図8に示す如く、着信報知窓部(51)、撮影窓部(52)及び画像表示窓部(53)を除く領域に、背面遮光膜(7)が形成されている(図9参照)。
【0014】
更に、化粧パネル(5)には、光透過性パネル本体(50)と背面遮光膜(7)の間に、図6中にハッチングを施した領域、即ち、着信報知窓部(51)と撮影窓部(52)を包囲する領域に拡がる光反射防止膜(6)が形成されている(図9参照)。尚、光反射防止膜(6)は、黒色の塗料を用いた印刷によって容易に形成することが出来る。
【0015】
上記折り畳み式携帯電話機においては、着信や画像撮影の報知のために着信報知LED(31)が発光し、その光線が、図9中に矢印で示す如く着信報知窓部(51)を透過して、前方へ向けて放射される。又、サブディスプレイ(33)に画像を表示した場合、サブディスプレイ(33)からの映像光が画像表示窓部(53)を透過して、前方へ向けて放射される。又、CCDカメラ(32)を用いた画像撮影時には、前方からの映像光が着信報知窓部(51)を透過して、CCDカメラ(32)に入射する。
【0016】
ここで、図9の如く着信報知LED(31)やサブディスプレイ(33)から斜め方向に出射された光線は、前面遮光膜(8)にて反射された後、CCDカメラ(32)へ向かって進むが、これらの光線の大部分が光反射防止膜(6)へ入射して、光反射防止膜(6)での反射が防止されることになる。
従って、CCDカメラ(32)を用いた画像撮影時に、着信報知LED(31)やサブディスプレイ(33)からCCDカメラ(32)へ導かれる光の量は、図10に示す従来の携帯電話機の場合よりも大幅に減少する。
【0017】
この結果、本発明に係る折り畳み式携帯電話機によれば、CCDカメラ(32)を用いた撮影において、着信報知LED(31)やサブディスプレイ(33)からの光の影響を受けない、高画質の映像を得ることが出来る。
又、光反射防止膜(6)は、光透過性パネル本体(50)と背面遮光膜(7)との間に介在しているので、前面遮光膜(8)には、光反射防止膜(6)の材質や製法に拘わらず、蓋体(2)のケースと同色の色彩或いはその他の自由な色彩を採用して、意匠としての効果を発揮させることが出来る。
【0018】
尚、本発明の各部構成は上記実施の形態に限らず、特許請求の範囲に記載の技術的範囲内で種々の変形が可能である。例えば、光反射防止膜(6)は、光透過性パネル本体(50)と前面遮光膜(8)の間に形成し、或いは、光透過性パネル本体(50)の両面に形成することも可能である。更に、背面遮光膜(7)を光反射防止膜(6)に代えて、背面遮光膜(7)を省略することも可能である。又、CCDカメラ(32)に代えてCMOSカメラを採用することも可能である。更に、発光デバイスとして、画像撮影時に発光するフラッシュを配備した構成も採用可能である。
また本発明は、折り畳み式携帯電話機に限らず、カメラと種々の発光デバイスとを同一面上に並設した種々の携帯型通信端末機に実施することが可能である。
