Description
【０００１】[0001]
本発明は、テレビジョン受像機に関するもので、特に、外光の明るさを検出し てテレビジョン受像機を自動的に制御する機能を備え、更に、リモコン信号によ り各機能を制御することができるテレビジョン受像機に関するものである。 The present invention relates to a television receiver, and in particular, has a function of automatically controlling the television receiver by detecting the brightness of external light, and further controlling each function by a remote control signal. The present invention relates to a television receiver that can do.
【０００２】[0002]
従来、テレビジョン受像機を視聴している人の目を、なるべく疲れさせないよ うにするためにその周辺の明るさによって画面の明るさを適切に自動調整する機 能を持ったテレビジョン受像機がすでに実公平１−３２５７号公報（Ｈ０４Ｎ５ ／５８）で提案されている。 Conventionally, there is a television receiver that has a function of automatically adjusting the brightness of the screen appropriately according to the brightness of the surroundings in order to prevent the eyes of a viewer of the television from getting tired as much as possible. It has already been proposed in Japanese Utility Model Publication No. 1-3257 (H04N5 / 58).
【０００３】 このようなテレビジョン受像機には、明るさ検出用のセンサが組み込まれてお り、そのセンサはテレビジョン受像機外部の明るさ検出を容易にするため、図１ １及び図１２に示すように、テレビジョン受像機のパネル１の部分に光透過率の 良好な明るさ検出用の窓部２４を設けている。（この窓部２４は、光透過率の良 い樹脂で構成されている）このパネル１の前方部へプリント基板３が配置される 。Such a television receiver has a built-in sensor for detecting brightness, and the sensor facilitates detection of brightness outside the television receiver. As shown in FIG. 3, a window portion 24 for detecting brightness having a good light transmittance is provided in the panel 1 portion of the television receiver. (The window portion 24 is made of a resin having a high light transmittance.) The printed circuit board 3 is arranged in the front portion of the panel 1.
【０００４】 そして、窓部２４を介して外光が明るさ検出用センサ９に入射され、明るさ検 出センサ９は、プリント基板３上に取り付けられテレビジョン受像機の輝度やコ ントラストなどを制御するため図示しない信号処理回路へその出力を供給する。Then, external light is incident on the brightness detection sensor 9 through the window 24, and the brightness detection sensor 9 is mounted on the printed circuit board 3 to detect the brightness and contrast of the television receiver. The output is supplied to a signal processing circuit (not shown) for control.
【０００５】 一方、今日、ほとんどのテレビジョン受像機はリモコン送信機および受信機を 有しており、遠隔操作が可能となっている。（図６にリモコン信号受光部の外観 を示す。） そこで、テレビジョン受像機には図示しないリモコン送信機からの信号の受信 を容易にするため、パネル１に前述の明るさ検出用の窓部２４とは別に、リモコ ン信号受光用の窓部２３を設けている。このリモコン信号受光用の窓部２３は、 パネル１に赤外線のみを通過させるような樹脂を塗布することで実現される。こ のような技術は、例えば、実開昭６１−１６５５０２号公報（Ｇ０２Ｂ５／２２ ）に示されるようなものが提案されている。On the other hand, most television receivers today have a remote control transmitter and a receiver, which enables remote control. (FIG. 6 shows the appearance of the remote control signal light receiving unit.) Therefore, in order to facilitate reception of a signal from a remote control transmitter (not shown) in the television receiver, the above-mentioned window portion for brightness detection on the panel 1 In addition to 24, a window portion 23 for receiving the remote control signal is provided. The window portion 23 for receiving the remote control signal is realized by coating the panel 1 with a resin that allows only infrared rays to pass therethrough. As such a technique, for example, a technique disclosed in Japanese Utility Model Laid-Open No. 61-165502 (G02B5 / 22) is proposed.
【０００６】 そして、リモコン信号は、このリモコン信号受光用の窓部２３を介して、プリ ント基板３上にあるリモコン受光部７の受光部窓８へ入射されて、リモコン信号 をテレビジョン受像機が受信する構成になっいる。Then, the remote control signal is incident on the light receiving section window 8 of the remote control light receiving section 7 on the printed circuit board 3 through the window section 23 for receiving the remote control signal, and the remote control signal is transmitted to the television receiver. Is configured to receive.
【０００７】 ところで、このように、明るさ検出用窓部とリモコン信号用受光窓部とが、別 々の窓部を有する理由を説明する。By the way, the reason why the brightness detection window portion and the remote control signal light reception window portion have different window portions will be described.
【０００８】 リモコン信号受信用の窓には、リモコン送信機からの信号は赤外線を利用して いるため、先にも述べたように可視光カットフィルター特性を持つ窓部２３を使 用している。リモコン受光部ではおもに赤外線領域の波長を持つ信号に対して感 度の高いフォトダイオードやフォトトランジスタを用いてリモコン信号を受光し ている。As the signal from the remote control transmitter uses infrared rays, the window 23 having the visible light cut filter characteristic is used for the window for receiving the remote control signal, as described above. . The remote control light receiving unit receives the remote control signal mainly by using a photodiode or phototransistor that is highly sensitive to signals having wavelengths in the infrared region.
【０００９】 しかしながら、フォト・ダイオードやフォト・トランジスタの感度が最も高く なるところが、赤外線領域となってはいるが、可視光領域に対して全く反応しな いわけではなく、相対的に可視光領域よりは、赤外線領域の方が検出感度が良い だけである。However, although the sensitivity of the photo diode or photo transistor is the highest in the infrared region, it does not completely react to the visible light region, and the visible light region is relatively insensitive. Rather, the infrared region only has better detection sensitivity.
【００１０】 このため、リモコン送信機からのリモコン信号以外の光を信号として検出して しまい、テレビジョン受像機を誤動作させることが希にあるため、透過率が赤外 線領域に対しては高く、可視光領域に対しては低い、前述の可視光カットフィル ターがリモコン信号受信用の窓部に設けられる。Therefore, since it is rare that light other than the remote control signal from the remote control transmitter is detected as a signal and the television receiver malfunctions, the transmittance is high in the infrared ray region. The above-mentioned visible light cut filter, which is low in the visible light region, is provided in the window portion for receiving the remote control signal.
【００１１】 一方、明るさ検出は、人間の可視光を検出する必要があり、先のリモコン信号 である赤外線とは、全く逆のことをしなければならない。On the other hand, for the brightness detection, it is necessary to detect human visible light, and it is necessary to do the opposite of the infrared ray which is the remote control signal.
【００１２】 従って、明るさ検出用窓部とリモコン信号受光用窓部とは、それぞれ別々の場 所に設けなくてはならないため、リモコン受光部と明るさ検出センサを配置する プリント基板の面積を余分に取らなくてはならず、また、テレビジョン受像機の パネルに２つの窓部が必要となり、その窓部にフィルタ特性などをもたせるよう な加工を必要としなければならないと言う問題があった。Therefore, the window for detecting the brightness and the window for receiving the remote control signal must be provided in different places. Therefore, the area of the printed circuit board on which the remote control light receiving section and the brightness detection sensor are arranged is reduced. There was a problem that it had to be taken extra, and that the television receiver panel had to have two windows, and that the windows had to be processed so as to have filter characteristics and the like. .
【００１３】[0013]
本考案は、以上の点に鑑みなされたものであり、テレビジョン受像機のパネル のリモコン信号受光用窓部と外光の明るさ検出用窓部とを共用して、パネルの加 工を削減し、また、リモコン信号受光部と明るさ検出部のプリント基板の面積を 削減したテレビジョン受像機を提供することを目的とする。 The present invention has been made in view of the above points, and reduces the panel processing by sharing the window for receiving the remote control signal of the panel of the television receiver and the window for detecting the brightness of external light. It is also an object of the present invention to provide a television receiver in which the area of the printed circuit board for the remote control signal light receiving section and the brightness detecting section is reduced.
【００１４】[0014]
本考案、テレビジョン受像機の各機能を遠隔制御する光リモコン信号を受光す るリモコン受光部と、テレビジョン受像機の外部の明るさを検出する明るさ検出 部と、上記リモコン受光部と明るさ検出部にリモコン信号及び外光をそれぞれ入 射させるためのテレビジョン受像機に設けられた受光窓とを備えるテレビジョン 受像機において、上記リモコン受光部と明るさ検出部とを近接して配置し、上記 リモコン受光部用受光窓と明るさ検出部用受光窓とを共用したことを特徴とする テレビジョン受像機である。 The present invention, a remote control light receiving section for receiving an optical remote control signal for remotely controlling each function of the television receiver, a brightness detection section for detecting the external brightness of the television receiver, the remote control light receiving section and the brightness. In a television receiver including a remote control signal and a light receiving window provided in a television receiver for emitting external light to the detection unit, the remote control light receiving unit and the brightness detection unit are arranged close to each other. The television receiver is characterized in that the light receiving window for the remote control light receiving portion and the light receiving window for the brightness detecting portion are shared.
【００１５】[0015]
本考案は、以上のような構成にしたことで、パネルの受光窓をリモコン信号受 光用と明るさ検出用と共用したので、パネルの加工の削減が図れる。 According to the present invention, with the above-mentioned configuration, the light receiving window of the panel is commonly used for receiving the remote control signal and for detecting the brightness, so that the panel processing can be reduced.
【００１６】[0016]
以下、本考案を図面を参照しながら説明をする。図１は本考案の実施例を示し 、従来技術で示した図番と同じものは同一構成であるため説明は割愛する。 Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of the present invention, and the same reference numerals as those shown in the prior art have the same structure, and the description thereof will be omitted.
【００１７】 まず、図１及び図２において、２はリモコン信号と外光を受光するための受光 窓部であり、この窓部２は、光透過率の高い樹脂から構成されている。そして、 このパネル１は、図２に示す如くテレビジョン受像機の前部に取り付けられてい る。First, in FIGS. 1 and 2, reference numeral 2 denotes a light receiving window portion for receiving a remote control signal and external light, and the window portion 2 is made of a resin having a high light transmittance. The panel 1 is attached to the front of the television receiver as shown in FIG.
【００１８】 また、４はリモコン信号受光と明るさを検出するための受光部で、リモコン信 号を受光するための窓６と明るさを検出するための窓５が設けられており、プリ ント基板上３に固定されている。Reference numeral 4 denotes a light receiving section for receiving a remote control signal and detecting brightness, which is provided with a window 6 for receiving a remote control signal and a window 5 for detecting brightness. It is fixed on the substrate 3.
【００１９】 そして、この受光部４は、図５に示す如く、全体がシールド板４１で囲まれて おり、その内部には、フォト・ダイオードやフォト・トランジスタ等の赤外線セ ンサ１０と明るさ検出用センサ１１がそれぞれの受光窓６、５に対して配置され ている。As shown in FIG. 5, the light receiving unit 4 is wholly surrounded by a shield plate 41, and inside the light receiving unit 4, an infrared sensor 10 such as a photo diode or a photo transistor and a brightness detection unit are provided. Sensors 11 are arranged for the respective light receiving windows 6 and 5.
【００２０】 この受光部４が配置されたプリント基板３をパネル１の前方に配置することに より図７に示すように矢印（テレビジョン受像機外部）からの光を受光部へ導き いれる。By arranging the printed circuit board 3 on which the light receiving section 4 is arranged in front of the panel 1, light from an arrow (outside the television receiver) can be guided to the light receiving section as shown in FIG.
【００２１】 ところで、この受光部４内のセンサ１０は、フォト・ダイオードまたはフォト ・トランジスタで、赤外線のみを通過させるような特性、即ち、図９に示すよう に赤外線の９００ｎｍの波長を通過させる特性となっている。更に、フォト・ダ イオードのチップに染料（赤外線を通過させる染料）を混ぜた液体樹脂でモール ドしてチップを固めることにより、上記特性からさらに赤外線のみ通過させるよ うな特性を形成し、チップへ赤外線のみ通過させることができるようにしている 。By the way, the sensor 10 in the light receiving unit 4 is a photodiode or a phototransistor, and has a characteristic of allowing only infrared rays to pass therethrough, that is, a characteristic of passing infrared wavelengths of 900 nm as shown in FIG. Has become. Furthermore, by molding the photo diode chip with a liquid resin mixed with a dye (a dye that allows infrared rays to pass through) and solidifying the chip, the characteristics described above that allow only infrared rays to pass through are formed. Only infrared rays can pass through.
【００２２】 一方、センサ１１は、明るさ検出用のため図１０に示すような特性をもつアモ ルファスの太陽電池を用いており、人間の目で見る明るさを検出するため６００ ｎｍ前後の波長を通過させる特性を有している。On the other hand, the sensor 11 uses an Amorphus solar cell having the characteristics shown in FIG. 10 for brightness detection, and has a wavelength of about 600 nm for detecting the brightness seen by human eyes. Has the property of passing through.
【００２３】 従って、パネル１の受光窓部２は、赤外線を通過させる窓部などは必要なく、 光透過性の高いもので構成すれば良く、共用した窓部２とすることができる。Therefore, the light receiving window portion 2 of the panel 1 does not need a window portion or the like that allows infrared rays to pass therethrough, and may be formed of a material having a high light transmittance, and the window portion 2 can be shared.
【００２４】 また、受光部をリモコン信号受光センサと明るさ検出用センサとを両方内蔵す ることができるため、プリント基板の面積を少なくできる。Further, since the light receiving section can incorporate both the remote control signal light receiving sensor and the brightness detecting sensor, the area of the printed circuit board can be reduced.
【００２５】 次に、第２実施例として、図３及び図５に示すような方法も取ることができる 。即ち、パネル１には、共通の光透過性の高い受光窓部２２を設け、プリント基 板３上へは、明るさ検出センサ９をパネル１に近い方へ配置し、受光部７をセン サ９の後方へ配置し、センサ９の高さを受光部７の受光窓８よりも低い位置につ けるよう配置する。Next, as a second embodiment, the method shown in FIGS. 3 and 5 can also be adopted. That is, the panel 1 is provided with a common light receiving window portion 22 having a high light transmission property, the brightness detection sensor 9 is arranged on the printed board 3 in the vicinity of the panel 1, and the light receiving portion 7 is arranged as a sensor. The sensor 9 is disposed rearward of the sensor 9 so that the height of the sensor 9 is lower than the light receiving window 8 of the light receiver 7.
【００２６】 尚、このときの明るさ検出用センサ９は、先ほど示したアモルファス太陽電池 でも良いし、従来からあるセンサでも良い。また、リモコン信号受光部７は、図 ６に示すように、先ほど説明したセンサ１０と同じ赤外線センサ１２が内蔵され て、シールド板７１で囲まれている。The brightness detecting sensor 9 at this time may be the above-mentioned amorphous solar cell or a conventional sensor. Further, as shown in FIG. 6, the remote control signal light receiving unit 7 has an infrared sensor 12 which is the same as the sensor 10 described above built therein and is surrounded by a shield plate 71.
【００２７】 また、第３の実施例として図４に示すような方法をとることもできる。即ち、 明るさ検出用センサ９とリモコン信号受光部７を横に並べて、パネル１に設けた 受光用窓部２１を１つ設ければ良い。このとき、窓部２１の面積を大きめにして やれば、リモコン信号受光部７と明るさセンサ９に十分光が入ることは言うまで もない。Further, as a third embodiment, a method as shown in FIG. 4 can be adopted. That is, the brightness detecting sensor 9 and the remote control signal light receiving portion 7 may be arranged side by side, and one light receiving window portion 21 provided on the panel 1 may be provided. At this time, needless to say, if the area of the window portion 21 is increased, sufficient light can enter the remote control signal light receiving portion 7 and the brightness sensor 9.
【００２８】[0028]
以上、本考案によれば、テレビジョン受像機を構成するパネルの窓部とプリン ト基板の面積を削減でき、リモコン受光部と明るさセンサを一体化することがで きる。 As described above, according to the present invention, it is possible to reduce the areas of the window portion of the panel and the print substrate that form the television receiver, and to integrate the remote control light receiving portion and the brightness sensor.
【００２９】 更に、明るさ検出機能がなく、リモコン操作のみが可能なテレビジョン受像機 において、新たに、明るさ検出機能を追加する場合、通常、この窓はテレビジョ ン受像機のキャビネット部品に設けられているため、明るさ検出専用の窓を新た に設けるには、その金型の変更も容易でない。Further, in a television receiver which does not have a brightness detection function and can be operated only by a remote controller, when the brightness detection function is newly added, this window is usually a cabinet part of the television receiver. Since it is provided, it is not easy to change the mold to newly provide a window for brightness detection.
【００３０】 しかし、この技術を用いれば、テレビジョン受像機の構造部品の変更は、窓の 材質を可視光カットフィルター特性から、光透過率がよく、とくにフィルタ特性 を持たない材質に変更するだけでよいので、容易に金型の変更ができる。However, if this technology is used, the structural parts of the television receiver can be changed only by changing the material of the window from a visible light cut filter characteristic to a material having a good light transmittance and no particular filter characteristic. Since it is good, the mold can be easily changed.
【００３１】 また、光透過性の良い窓を１つ設けたパネルで、明るさ検出とリモコン信号検 出を共用でき、また、リモコン信号検出用のみでも使用できるためパネルが全て の機種に対応できる。In addition, the panel provided with one window with good light transmission can share brightness detection and remote control signal detection, and can be used only for remote control signal detection, so the panel can be applied to all models. .
