Description of the Related Art In general, a dosing type television receiver includes a dosing machine that magnifies and administers the image projected on a cathode ray tube using a lens system, and a concave screen that projects the administered image separately from the dosing machine. There are two types: one is a separate type with a cathode ray tube, and the other is a relatively small integrated type that reflects the image projected from a cathode ray tube on a mirror plate and projects it onto the back of the screen so that the screen can be viewed from the front of the screen. There is. The latter is compact because it is constructed by housing the part that projects the image from the cathode ray tube, the mirror plate, and the screen into one body.
Although it is extremely common and can be installed freely, it is extremely complicated to adjust the angle of attaching the mirror plate that reflects the projected image optical path onto the screen.

上方向に押上げられるようになる。This mirror plate 13 is provided with a fulcrum 15 at a location shifted from its center to one side, and this fulcrum 15 is rotatably supported from both sides. In this way, the mirror plate longer than the fulcrum (11 in Figure 1) is always loaded downward, and conversely, the mirror plate shorter than the fulcrum (42 in Figure 1) is pushed upward. be able to raise it.
そこで、その短い方の一部に当接するビス１６を鏡面板

り光路を調整出来る。Therefore, a screw 16 that abuts on a part of the short side is provided on the back side of the mirror plate, so that the angle of the mirror plate 13 can be adjusted by adjusting the degree of screwing. If the head 17 of this screw 16 is arranged so as to be exposed from the top plate 18 of the casing, the optical path can be adjusted by changing the angle of the mirror plate without opening the back cover of the casing or the like.
光路の調整が終了すれば、鏡面板１３に一体に設けた固
定具１９をビス２ｏで締め付けるようにすれば、鏡面板
を完全に調整位置に固定出来る。Once the adjustment of the optical path is completed, the mirror plate can be completely fixed at the adjusted position by tightening the fixture 19 integrally provided on the mirror plate 13 with the screws 2o.
この場合ビス２０の締付けは、通常の生活上発生する振

く容易に光路の調整が出来るものである。In the optical path adjusting device configured as above, the mirror plate is always loaded on the longer side than the fulcrum, and vice versa.
The short side of 1 is pushed upwards around the entire center of the fulcrum, so if you tighten the screw from the back of the mirror plate at that part using a means to adjust the angle depending on the degree of screwing, the mirror plate will move around the fulcrum. The light path can be adjusted very easily by changing the reflection angle of the mirror plate. In addition, by exposing the head 17 of the adjustment screw 16 on the top plate of the housing as shown in Figure 1, the above optical path adjustment operation can be performed from outside the housing, making it easier to use during service. The optical path can be easily adjusted without opening the back cover of the housing.
