ヲ得るに好適なグロジェクシ。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a rear projection type projection television;
This is particularly suitable for obtaining a large-screen or compact grosgeection TV.
ヨンテレビの反射鏡に関する。Regarding Yong TV's reflector.
従来の背面投射形のグロジエクションテレビ。 Traditional rear projection type Gloziection TV.
においでは第１図に示すようにキャビネット１の内部に
反射鏡２がブラケット５を介して取り。As shown in FIG. 1, a reflector 2 is installed inside the cabinet 1 via a bracket 5.
付いており、第２図に示すようにキャビネット１の横巾
はブラケット５の・１゛法を除きほぼ反射。As shown in Figure 2, the width of the cabinet 1 is almost reflective except for the 1 inch width of the bracket 5.
鏡２の横巾で決まっており反射鏡２は長方形を゛してい
るためキャビネット１もほぼ角形の形状となりコンパク
トな形状に７ｆｉ来ないという欠点゛があつ１こ。It is determined by the width of the mirror 2, and since the reflecting mirror 2 has a rectangular shape, the cabinet 1 also has an almost rectangular shape, and there is one drawback that it is not 7fi despite its compact shape.
本発明の目的は」−記欠点をなくすため反射鏡・２を光
の反別に必要な部分だけと１−極カ小面積穎とし・針ヤ
ビネットもその分小さくする事により。The purpose of the present invention is to eliminate the drawbacks described above by making the reflecting mirror 2 only the part necessary for separating the light and having a very small area, and by making the needle thread net that much smaller.
大画面かつコンパクトなグロジェクシ目ンテレ・ビを提
供することにある。The objective is to provide a large-screen and compact television.
本発明は、グロジエクシ目ンテレビはプラウ１−ン管の
画面をレンズで拡大しスクリーン上に写。The present invention is a digital camera that uses a lens to magnify the screen of a 1-tube tube and displays it on the screen.
す方法であり、レンス゛がらスクリーンまでの光。This is a method that allows the light to reach the screen through the lens.
の断面はスクリーンから遼いところ程小面積と。The cross-section of the screen is as small as the distance from the screen.
なる。したがってスクリーンに対して反射鏡は。Become. Therefore, the reflector is relative to the screen.
傾けているためスクリーンから遠い反射鏡の後５゜部は
前部より小面積で済むため「１フも挾くする事゛が可能
である。従って反射鏡を従来の長方形か゛ら略台形とす
る事によりキャビネット後部をそ。Because it is tilted, the rear 5° part of the reflector, which is far from the screen, requires a smaller area than the front part, so it is possible to "sample even one frame."Therefore, the reflector can be made approximately trapezoidal instead of the conventional rectangle. Remove the back of the cabinet.
の分挾くする事が出来る。It is possible to divide it into parts.

８に投射されるが光の光路７はスクリっ。[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to FIGS. 4 to 6. In FIG. 4, a reflector 5 is attached to the inside of the cabinet 4 via a bracket 6, and as shown in FIG.
The rear width of the cabinet 4 is made into a trapezoid whose rear width is smaller than the front width, and the dimensional difference between the front width and the rear width of the reflector is made smaller in the rear ten parts of the cabinet 4. Also, as shown in Fig. 5.6, the light from the Braun tube 10 is magnified by the lens 9, reflected by the reflection mirror 121, reflection mirror 115, and projected onto the screen 8, but the optical path of the light is 7 is scree.
ン８から遠くなる程幅が挾くなる。従フて第６゜図に示
すように反射鏡５はスクリーン８に対し。The further away from ring 8, the narrower the width. Therefore, as shown in FIG. 6, the reflecting mirror 5 is directed toward the screen 8.
傾いて取り付いているため第５図で示すように、反射鏡
５の後部で反射する光路７の幅が前部で。Because it is mounted at an angle, the width of the optical path 7 reflected at the rear of the reflector 5 is the same as that at the front, as shown in Figure 5.
反射する光路７の幅より挾いため前述のように、。As mentioned above, it is wider than the width of the reflected optical path 7.
反射鏡５の後部の幅を前部より挾〈ても光路７゜をさえ
ぎることはなく画像に影響を与えること゛はない。従っ
て本実施例によれば大画面でセット後部を小さくする効
果がある。Even if the width of the rear part of the reflecting mirror 5 is sandwiched from the front part, the optical path 7° will not be blocked and the image will not be affected. Therefore, this embodiment has the effect of making the rear part of the set smaller on a large screen.

It has the effect of looking very smart because of its low C color. 1...
