【発明の属する技術分野】
本発明は、例えば赤外線等を用いた光学式のリモートコントローラからの光信号を受ける受光素子を備えたリモコン受光装置、及びこのリモコン受光素子を備えた電子機器に関する。
【０００２】
【従来の技術】
従来、この種のリモコン受光素子としては、例えばリモートコントローラからの赤外線等の発光信号を受光する導光体を機器の表面に臨ませて配置し、導光体の背部に発光信号を受けて機器の制御部に信号を出力する受光素子を備えるリモートコントロール用の受光部構造であって、導光体の前面を前方に突出しないフレネルレンズとして光の集光性を向上させたものがあった（例えば、特許文献１参照）。

【発明が解決しようとする課題】
上記のような従来の受光部構造において、フレネルレンズを使用している構造のものでは、そのレンズ形状のために受光部の断面形状や外観形状が制約される、と言った欠点があった。また光ファイバを使用している構造のもの、及びシールドカバーを設けている構造のものでは、コストが高くなってしまうといった問題点があった。
【０００６】
本発明の目的は、以上の問題点を解消すべく、意匠、外観上の制約なしに、且つ安価に受光角度（入射角度）の大きなリモコン受光装置を提供することにある。
【０００７】
【課題を解決するための手段】
本発明によるリモコン受光装置は、赤外線を用いるワイヤレスリモコンからの信号を受光するリモコン受光装置において、
赤外線を通過させる赤外線受光部窓と、該赤外線受光部窓と共に赤外線受光素子設置用空間を形成する容体部と、該容体部の壁面から前記赤外線受光素子設置用空間に、その受光部が臨むように保持された赤外線受光素子と、前記容体部の前記赤外線受光素子設置用空間に面する壁面に設けられ、前記赤外線を反射する反射膜層とを有することを特徴とする。
【０００８】
また、本発明によるリモコン受光装置を備えた電子機器は、上記リモコン受光装置を備えた電子機器において、
外筐の所定位置に前記容体部を形成すると共に、前記所定位置の周囲表面と面一に前記赤外線受光部窓を配設したことを特徴とする。
【０００９】
【発明の実施の形態】
実施の形態１．
図１は、本発明によるリモコン受光装置の実施の形態１の要部構成を示す断面図である。
【００１０】
同図中、電子機器の外筐２の所定位置には、リモコン受光装置１を構成する容体部３が形成されている。この容体部３の周縁には段部３ａが形成され、この段部３ａには、リモコンから発射された赤外線が通過する赤外線受光部窓４が装着されている。この容体部３と赤外線受光部窓４とによって、例えば円柱状の赤外線受光素子設置用空間７が形成され、段部３ａの深さは、赤外線受光部窓４が周辺表面と面一となるように考慮されている。
【００１１】
受光素子５は、容体部３の底部３ｃの中央部において、その受光面５ａが底部３ｃの底面と略面一となる位置で固定配置されている。また容体部３の側面３ｂの内側である内壁面には、赤外線を反射するアルミ箔などの反射膜層６が配設されている。赤外線経路１０ａ，１０ｂは、赤外線受光部窓４を通過して赤外線受光素子設置用空間７に至る赤外線の内、受光素子５に直接至る最大入射角度、即ち反射膜層６が形成されていない場合の最大入射角度の赤外線の経路を示している。また、赤外線経路１１ａ，１１ｂは、赤外線受光部窓４を通過して赤外線受光素子設置用空間７に至り、且つ反射層６で反射した反射光が受光素子５に至る際のある入射角度の赤外線の経路を示している。
【００１２】
以上のように構成されたリモコン受光装置１おいて、その動作について説明する。
【００１３】
赤外線経路１１ａに沿ってリモコン送信機（図示せず）から発射された赤外線は、赤外線を通過する赤外線受光部窓４を通過して赤外線受光素子設置用空間７に到達し、アルミ箔等の赤外線を反射する機能を有する反射膜層６に当り、受光素子５の中心軸線１００に対して一定の角度の赤外線経路１１ｂに沿って受光素子５に到達する。このように、リモコン受光装置１によると、リモコンから発射された赤外線は、反射膜層６によって１回又は複数回の反射の後、受光素子５に到達することが可能となる。
【００１４】
図２は、本実施の形態１のリモコン受光装置１の赤外線受光特性を示した特性図である。
【００１５】
同特性図は、その中心部Ｏが、リモコン受光装置１の赤外線受光部窓４の中心部近傍に相当し、中心部Ｏから放射状に引かれた放射状目盛が、受光素子５の中心軸線１００を含む平面、例えば図１に示す断面における受光素子５の中心軸線１００に対する入射角度を示し、円弧状の目盛が、入射する赤外線の受光強度を示し、そして所定強度の赤外線を、各入射角で中心部Ｏに当てたときの受光素子５による受光強度をプロットしたものである。
【００１６】
同図において、プロット線５０（実線）は、反射膜層６を除いた場合の実測値を示し、プロット線５１（破線）は、反射膜層６を設けた場合の実測値を示している。この実測結果を示す各プロット線の特性から理解されるように、反射膜層６を設けることによって、入射角の大きな角度から入射する赤外線に対する受光感度が飛躍的に高くなる。
【００１７】
以上のように、実施の形態１によるリモコン受光装置１によれば、反射膜層６を設けることによって、電子機器の外筐の意匠に影響を与えることなく、受光入射角範囲の大きなリモコン受光装置を提供できるので、デザイン的な自由度を保ったまま、広い入射角位置でのリモコン操作を可能とすることができる。
【００１８】
実施の形態２．
図３は、本発明によるリモコン受光装置の実施の形態２の要部構成を示す断面図である。
【００１９】
この実施の形態２のリモコン受光装置２１が、前記した実施の形態１のリモコン受光装置１と主に異なる点は、容体部３の側面３ｂにアルミ箔などの反射膜層６ではなく、鏡面仕上げされた反射膜層２２を設けた点である。従って、このリモコン受光装置２１が、前記した実施の形態１のリモコン受光装置１と共通する部分には同符号を付して説明を省略し、異なる点を重点的に説明する。
【００２０】
容体部３の側面３ｂの内側である内壁面は、この内壁と一体で且つ鏡面仕上げされた反射膜層２２を形成している。従って、赤外線経路１１ａに沿ってリモコン送信機（図示せず）から発射された赤外線は、赤外線を通過する赤外線受光部窓４を通過して赤外線受光素子設置用空間７に到達し、鏡面仕上げされた反射膜層２２に当り、受光素子５の中心軸線１００に対して一定の角度の赤外線経路１１ｂに沿って受光素子５に到達する。
【００２１】
以上のように、実施の形態２によるリモコン受光装置２１によれば、アルミ箔のような別部品を使用することなく、受光素子設置用空間の内壁に鏡面仕上げによる反射膜層２２を形成しているので、実施の形態１のリモコン受光装置１と同様の効果を得ることができる外に、部品点数を減らして構成を簡単にすることができるため、製造コストの削減にも寄与することができる。
【００２２】
実施の形態３．
図４は、本発明によるリモコン受光装置を備えた電子機器としてのプロジェクタ３１における設置例を概略的に示す実施の形態３の概略構成図である。
【００２３】
同図に示すように、プロジェクタ３１は、これを設置する部屋３４の天井３４ｃに、取り付け部材３３を介して取り付けられる。映像を投写するプロジェクタ３１の前面３１ａは、部屋３４の壁３４ａに配設されたスクリーン３２に対向しており、更にこのプロジェクタ３１の前面３１ａには、前記した実施の形態１で説明した容体部３（図１）が形成され、これを構成要素とする前記したリモコン受光装置１が、その受光素子５（図１）の中心軸線１００をスクリーン３２の壁３４ａに対して略垂直となる向きにして、配設されている。
【００２４】
プロジェクタ３１を以上のように配置した場合、同図からも明らかなように、プロジェクタ３１の前面３１ａからスクリーン３２の投写面３２ａまでの距離が短い場合、前記したリモコン受光装置１の反射膜層６（図１）が形成されていな場合に受信可能な最大入射角度を示す赤外線経路１０ｂが、スクリーン３２に掛かってしまうことからも明らかなように、操作者は、壁３４ａが障害となってリモコンを使った操作ができない。
【００２５】
一方、前記したリモコン受光装置１の反射膜層６（図１）によって反射された後に受光素子５（図１）に到達する赤外線の経路を示す赤外線経路１１ａの延長線は、部屋３４の床３４ｂに達するため、この場合、操作者は、リモコンによってプロジェクタ３１を操作することが可能となる。
【００２６】
以上のように、本実施の形態に示す、リモコン受光装置１を採用したプロジェクタ３１によれば、設置時に限られたスペース空間しか確保できない場合においても、リモコンによってプロジェクタ３１を操作することが可能となる。
【００２７】
尚、前記実施の形態では反射膜層をアルミ箔や鏡面仕上げによって形成したが、これに限定されるものではなく、プラスチック樹脂の表面をメッキ仕上げすることで赤外線の反射効果を持たせる構成としてもよいし、その他に反射フィルムなどを設置することにより反射膜層を形成してもよい。
【００２８】
また、前記実施の形態では、赤外線受光素子設置用空間７が円柱状となるように構成したが、これに限定されるものではなく、用途に応じて、楕円柱状、或いは四角柱状となるように構成してもよい。
【００２９】
また、実施の形態３では電子機器としてプロジェクタを用いた例を示したが、これに限定されるものではなく、テレビ、ビデオ、ＤＶＤプレーヤー、ＣＤプレーヤー、ＡＶアンプなどの映像機器や音響機器をはじめ、エアコン、扇風機、ファンヒーターなどのリモコン送信機を使用して機器の制御を行う電子機器に用いてもよいなど、種々の態様を取り得るものである。
【００３０】
【発明の効果】
本発明によれば、電子機器の外筐の意匠に影響を与えることなく、受光範囲の大きなリモコン受光装置を提供することができるので、電子機器のデザイン的な自由度を保ったまま、広い入射角位置でのリモコン操作を可能とすることができる。

[0005]
[Problems to be solved by the invention]
In the above-described conventional light receiving unit structure, the structure using a Fresnel lens has a drawback that the sectional shape and the external shape of the light receiving unit are restricted by the lens shape. In the case of the structure using the optical fiber and the structure in which the shield cover is provided, there is a problem that the cost is increased.
[0006]
SUMMARY OF THE INVENTION An object of the present invention is to provide a remote control light-receiving device having a large light-receiving angle (incident angle) at low cost without any restrictions on design and appearance in order to solve the above problems.
[0007]

And a reflecting film layer provided on a wall surface of the container portion facing the space for installing the infrared light receiving element and reflecting the infrared light.
[0008]
Further, an electronic device including the remote control light receiving device according to the present invention is an electronic device including the remote control light receiving device,
The container portion is formed at a predetermined position of an outer casing, and the infrared light receiving unit window is disposed flush with a peripheral surface of the predetermined position.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiment 1 FIG.
FIG. 1 is a cross-sectional view showing a main configuration of a remote control light-receiving device according to a first embodiment of the present invention.
[0010]
In FIG. 1, a container 3 constituting the remote control light receiving device 1 is formed at a predetermined position on an outer casing 2 of the electronic device. A step 3a is formed on the periphery of the container 3, and an infrared light receiving window 4 through which infrared rays emitted from a remote controller pass is mounted on the step 3a. The container part 3 and the infrared light receiving window 4 form a columnar infrared light receiving element installation space 7, for example, and the depth of the step 3a is such that the infrared light receiving window 4 is flush with the peripheral surface. Is taken into account.
[0011]
The light receiving element 5 is fixedly arranged at the center of the bottom 3c of the container 3 at a position where the light receiving surface 5a is substantially flush with the bottom surface of the bottom 3c. A reflection film layer 6 such as an aluminum foil that reflects infrared rays is provided on an inner wall surface inside the side surface 3 b of the container 3. The infrared paths 10a and 10b are the maximum incident angles of infrared rays that pass through the infrared light receiving unit window 4 and reach the infrared light receiving element installation space 7 and directly reach the light receiving element 5, that is, when the reflective film layer 6 is not formed. Shows the path of the infrared ray at the maximum incident angle. The infrared paths 11a and 11b pass through the infrared light receiving window 4 to reach the space 7 for installing the infrared light receiving element, and the infrared light reflected at the reflective layer 6 reaches the light receiving element 5 at a certain incident angle. Is shown.
[0012]
The operation of the remote control light receiving device 1 configured as described above will be described.
[0013]
Infrared rays emitted from a remote control transmitter (not shown) along the infrared ray path 11a pass through the infrared ray receiving window 4 that passes infrared rays, reach the infrared ray receiving element installation space 7, and are irradiated with infrared rays such as aluminum foil. And reaches the light receiving element 5 along the infrared ray path 11 b at a certain angle with respect to the central axis 100 of the light receiving element 5. As described above, according to the remote control light receiving device 1, the infrared light emitted from the remote control can reach the light receiving element 5 after being reflected once or plural times by the reflective film layer 6.
[0014]
FIG. 2 is a characteristic diagram showing infrared light receiving characteristics of remote control light receiving device 1 of the first embodiment.
[0015]
In the characteristic diagram, the central part O corresponds to the vicinity of the central part of the infrared receiving part window 4 of the remote control light receiving device 1, and the radial scale drawn radially from the central part O corresponds to the central axis 100 of the light receiving element 5. 1, the incident angle with respect to the central axis 100 of the light receiving element 5 in the cross section shown in FIG. 1, the arc-shaped scale indicates the received light intensity of the incident infrared light, and the infrared light of a predetermined intensity is centered at each incident angle. The light receiving intensity by the light receiving element 5 when it hits the part O is plotted.
[0016]
In the figure, a plot line 50 (solid line) indicates an actual measurement value when the reflection film layer 6 is removed, and a plot line 51 (dashed line) indicates an actual measurement value when the reflection film layer 6 is provided. As can be understood from the characteristics of the plot lines indicating the actual measurement results, the provision of the reflective film layer 6 dramatically increases the light receiving sensitivity to infrared light incident from a large incident angle.
[0017]
As described above, according to the remote control light receiving device 1 according to the first embodiment, by providing the reflection film layer 6, the remote control light receiving device having a large light incident angle range can be obtained without affecting the design of the outer casing of the electronic device. Therefore, it is possible to operate the remote controller at a wide incident angle position while maintaining the degree of freedom in design.
[0018]
Embodiment 2 FIG.
FIG. 3 is a cross-sectional view illustrating a main part configuration of a remote control light-receiving device according to a second embodiment of the present invention.
[0019]
The main difference between the remote control light-receiving device 21 of the second embodiment and the remote control light-receiving device 1 of the first embodiment is that the side surface 3b of the container 3 is not mirror-reflective film layer 6 such as aluminum foil, but is mirror-finished. This is the point where the reflecting film layer 22 is provided. Therefore, in the remote control light-receiving device 21, portions common to the above-described remote control light-receiving device 1 of the first embodiment are denoted by the same reference numerals, description thereof will be omitted, and different points will be mainly described.
[0020]
An inner wall surface inside the side surface 3b of the container 3 forms a reflective film layer 22 that is integrated with the inner wall and has a mirror-finished surface. Therefore, the infrared rays emitted from the remote control transmitter (not shown) along the infrared ray path 11a pass through the infrared ray receiving window 4 passing the infrared rays, reach the infrared ray receiving element installation space 7, and are mirror-finished. The light reaches the light receiving element 5 along the infrared path 11b at a certain angle with respect to the central axis 100 of the light receiving element 5.
[0021]
As described above, according to the remote control light-receiving device 21 according to the second embodiment, the reflection film layer 22 is formed on the inner wall of the light-receiving element installation space by mirror finishing without using another component such as aluminum foil. Therefore, in addition to obtaining the same effect as the remote control light-receiving device 1 of the first embodiment, the number of parts can be reduced and the configuration can be simplified, which can contribute to reduction of manufacturing cost. .

As is clear from the fact that the infrared path 10b indicating the maximum receivable angle of incidence when the image is not formed (FIG. 1) is hung on the screen 32, the operator is obstructed by the wall 34a. Cannot perform operations using.
[0025]
On the other hand, an extension of the infrared ray path 11a showing the path of the infrared ray that reaches the light receiving element 5 (FIG. 1) after being reflected by the reflection film layer 6 (FIG. 1) of the remote control light receiving device 1 is a floor 34b of the room 34. In this case, the operator can operate the projector 31 with the remote controller.
