以下、本発明の一実施の形態による受信装置を備えた表示装置について、図面を用いて説明する。   Hereinafter, a display device including a receiving device according to an embodiment of the present invention will be described with reference to the drawings.

図１は本発明の一実施の形態による受信装置を備えた表示装置の外観を示す斜視図、図２はその表示装置を側面から見た側面図、図３は装置本体の内部構造を示す斜視図である。   1 is a perspective view showing an appearance of a display device including a receiving device according to an embodiment of the present invention, FIG. 2 is a side view of the display device viewed from the side, and FIG. 3 is a perspective view showing an internal structure of the device main body. FIG.

図１、図２に示すように、表示装置は、装置本体１と、この装置本体１に設けた樹脂からなる支持部材としての支持アーム２と、この支持アーム２の先端部に回動可能なように取り付けられた薄型で平板形状の液晶ディスプレイなどのディスプレイ装置３と、前記支持アーム２の後端部側に装置本体１に対して回動可能なように取り付けた平板形状のアンテナ装置４とを備えている。   As shown in FIG. 1 and FIG. 2, the display device is rotatable to a device main body 1, a support arm 2 as a support member made of resin provided in the device main body 1, and a distal end portion of the support arm 2. A display device 3 such as a thin and flat liquid crystal display, and a flat antenna device 4 attached to the rear end of the support arm 2 so as to be rotatable with respect to the device body 1; It has.

また、装置本体１は、図３に示すように、樹脂からなる外装筐体１ａ内に、ディスプレイ装置３に画像を表示する駆動回路、テレビジョン放送を受信して前記駆動回路に受信信号を供給するチューナ、ディスプレイ装置３を含め、電源電圧を供給するための電源回路を搭載したメイン基板５を組み込むことにより構成されている。また、メイン基板５には、前記駆動回路、チューナ、電源回路の配線を行う配線パターンと、アースパターンとなるグランドパターンが銅箔により形成されてなお、図３においては、外装筐体１ａのうち、上部から被せる筐体を省略して示している。   Further, as shown in FIG. 3, the apparatus main body 1 receives a drive circuit for displaying an image on the display device 3 and a television broadcast in an exterior casing 1a made of resin, and supplies a reception signal to the drive circuit. The main board 5 including the power supply circuit for supplying the power supply voltage including the tuner and the display device 3 is incorporated. Further, the main board 5 is formed with a wiring pattern for wiring the drive circuit, the tuner, and the power supply circuit, and a ground pattern serving as an earth pattern with copper foil. In FIG. In addition, the casing that covers from the top is omitted.

アンテナ装置４は、平板形状のアクリル樹脂などの絶縁性基板の同一面上に、所定の形状の導体パターンを形成することにより複数のアンテナ基板を配置した構造である。   The antenna device 4 has a structure in which a plurality of antenna substrates are arranged by forming a conductor pattern of a predetermined shape on the same surface of an insulating substrate such as a flat acrylic resin.

図４は表示装置において、アンテナ装置４を含む受信装置の電気回路を示す電気回路図である。   FIG. 4 is an electric circuit diagram showing an electric circuit of a receiving device including the antenna device 4 in the display device.

図４に示すように、アンテナ装置４は、アンテナ６と、アンテナ６で受信した電波を増幅する増幅器７を搭載したアンテナ基板８ａ、８ｂとを有する。   As shown in FIG. 4, the antenna device 4 includes an antenna 6 and antenna substrates 8 a and 8 b on which an amplifier 7 that amplifies radio waves received by the antenna 6 is mounted.

メイン基板５には、チューナ９、電源ブロック１０、チューナ９や増幅器７などの機器を制御するマイクロコンピュータからなる制御部１１が搭載されている。ここで、チューナ９は、アンテナ６で受信し、増幅器７で増幅した電波を受信し、復調するものである。   On the main board 5, a control unit 11 including a microcomputer that controls devices such as a tuner 9, a power supply block 10, a tuner 9 and an amplifier 7 is mounted. Here, the tuner 9 receives and demodulates the radio wave received by the antenna 6 and amplified by the amplifier 7.

同軸線１２は、増幅器７で増幅した信号をチューナ９に入力し、電源線１３は、アンテナ基板８ａに搭載された増幅器７の電源をアンテナ基板８ｂに搭載された増幅器７の電源に供給する。また、制御線１４は、制御部１１からの制御信号をアンテナ基板８ｂに搭載された増幅器７と、アンテナ基板８ａに搭載された増幅器７に供給するものである。   The coaxial line 12 inputs the signal amplified by the amplifier 7 to the tuner 9, and the power line 13 supplies the power of the amplifier 7 mounted on the antenna substrate 8a to the power of the amplifier 7 mounted on the antenna substrate 8b. The control line 14 supplies a control signal from the control unit 11 to the amplifier 7 mounted on the antenna substrate 8b and the amplifier 7 mounted on the antenna substrate 8a.

図４において、メイン基板５の電源ブロック１０からの電源電圧は、アンテナ基板８ａの増幅器７にコイルＬ２を介して同軸線１２の信号線に供給している。この時、チューナ９に電源電圧が印加されないように、コンデンサＣ２で直流を遮断する。なお、チューナ９の入力インピーダンスは５０Ωとなっているため、コイルＬ２は高周波的にインピーダンスの高いインダクタンスを持っているものが望ましい。   In FIG. 4, the power supply voltage from the power supply block 10 of the main board 5 is supplied to the signal line of the coaxial line 12 via the coil L2 to the amplifier 7 of the antenna board 8a. At this time, the direct current is cut off by the capacitor C2 so that the power supply voltage is not applied to the tuner 9. Since the input impedance of the tuner 9 is 50Ω, it is desirable that the coil L2 has an inductance with a high impedance in terms of high frequency.

同軸線１２に供給された電源電圧は、コイルＬ１を介してアンテナ基板８ａの増幅器７の電源端子に供給されるとともに、電源線１３を通してアンテナ基板８ｂの増幅器７の電源端子に供給される。この時、増幅器７の出力に電源電圧が印加されないようにコンデンサＣ１で直流を遮断する。   The power supply voltage supplied to the coaxial line 12 is supplied to the power supply terminal of the amplifier 7 of the antenna substrate 8a through the coil L1, and is also supplied to the power supply terminal of the amplifier 7 of the antenna substrate 8b through the power supply line 13. At this time, the direct current is cut off by the capacitor C1 so that the power supply voltage is not applied to the output of the amplifier 7.

一方、アンテナ基板８ａ、８ｂの増幅器７を制御するための制御部１１の制御信号は、コイルＬ３を介して同軸線１２の信号線に制御信号が供給される。同軸線１２に供給された制御信号は、コイルＬ４を介してアンテナ基板８ｂの増幅器７の制御端子に供給されるとともに、アンテナ基板８ａの増幅器７の制御端子に供給される。この時、チューナ９に制御信号が印加されないように、コンデンサＣ３で直流を遮断する。   On the other hand, the control signal of the control unit 11 for controlling the amplifier 7 of the antenna substrates 8a and 8b is supplied to the signal line of the coaxial line 12 via the coil L3. The control signal supplied to the coaxial line 12 is supplied to the control terminal of the amplifier 7 of the antenna substrate 8b via the coil L4 and also to the control terminal of the amplifier 7 of the antenna substrate 8a. At this time, the direct current is cut off by the capacitor C3 so that the control signal is not applied to the tuner 9.

このようにアンテナ基板８ａとアンテナ基板８ｂとを電源線１３と制御線１４で接続することで、それぞれのアンテナ基板８ａ、８ｂとメイン基板５とは、１本の同軸線１２のみで接続すればよい。   Thus, by connecting the antenna board 8a and the antenna board 8b with the power line 13 and the control line 14, the antenna boards 8a and 8b and the main board 5 can be connected with only one coaxial line 12. Good.

本発明は、複数のアンテナを有する受信装置において、メイン基板とアンテナ装置との間の配線を少なくすることができ、機器の配線の簡素化に有効な発明である。   INDUSTRIAL APPLICABILITY The present invention is a receiving apparatus having a plurality of antennas, which can reduce the wiring between the main board and the antenna apparatus, and is effective for simplifying the wiring of the equipment.
