てしまう問題があった。In the above-mentioned prior art, the projection display devices are individually combined and the individual screens are connected side by side. Therefore, the width of the frame for fixing the screen is the same as that of the projection display device alone. Since the width of the frame is doubled and the engagement width of the frame is increased in anticipation of the thermal expansion of the screen, the width of the frame is further increased, and there is a problem that images, characters and the like on the screen are lost, making it difficult to see. Also, the appearance of high-definition broadcasting increases the sharpness of the screen, so that the frame fixing the screen is more conspicuous and makes it difficult to see the screen.
【０００５】そこで本発明の目的は投写型表示装置の枠

型投写型表示装置を提供するにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a combination projection display device in which the frame width of the projection display device is reduced in consideration of thermal expansion so that the screen can be easily viewed.

合わせたものである。In order to achieve the above-mentioned object, an elastic member is used to elastically deform the frame fixing the screen of the projection display device alone in the thermal expansion direction of the screen, and the amount of thermal expansion is reduced. The width of the screen locking the frame is reduced, the end face of the screen is fixed by the frame, and the outer shape of the frame is adjusted to the outer size of the projection display device alone at the lowest operating temperature.

とができる。[Function] Since the external dimensions of the frame are adjusted to the external dimensions of the single unit of the front projection display device when the operating temperature is the lowest, the width of the frames does not change due to the thermal expansion of the screen, and the elastic members are used. Since the outer shape is changed, the width of the frame can be kept small.

る係止量の最少を取る。In each of the figures, the screen of the projection type display device 1 is composed of a lenticular sheet 2 and a Fresnel lens sheet 3 which are overlapped with each other. The parts are also locked by upper and lower frames 5 having a U-shape, and the left and right frames 4 and the upper and lower frames 5 are made of an elastic member such as a metal spring material.
The left and right frames 4 are engaged with the left and right frames 7 with frame set screws 10, the left and right frames 7 are locked with the cover 9 with set screws 6, and the upper and lower frames 5 are engaged with the upper and lower frames 8 with frame set screws 10. The frame 8 is locked to the cover 9 by a set screw 6. As a result, the screen in which the lenticular sheet 2 and the Fresnel lens sheet 3 are overlapped is locked to the cover 9 via the left and right frames 4 and the upper and lower frames 5 made of elastic members. Further, the outer shape width W of the left and right frames 4 and the width W of the cover 9 are the same, the outer shape of the upper and lower frames 5 and the height H of the cover 9 are the same, and the frames 4 and 5 made of the elastic members are used as the lenticular sheet 2. And the Fresnel lens sheet 3 are pressurized, and the length l, the plate thickness t, and the thinned portions 4a and 5a in the figure are provided to set the pressing force of the left and right frames 4 and the upper and lower frames 5; Sheet 2 and Fresnel And the right and left frame 4 for locking Nzushito 3 to lock the width S1 of the upper and lower frame 5 in the longitudinal direction take minimal engagement amount.

実現できることとなる。Therefore, the width dimension S1 of the locking portion between the left and right frames 4 and the upper and lower frames 5 does not have to take into account the thermal expansion of the lenticular sheet 2 and the Fresnel lens sheet 3. The lenticular sheet 2 and the Fresnel lens sheet 3,
The width in the expansion direction is approximately 800 mm and the operating temperature changes 50
℃, thermal expansion coefficient 8 × 10 ~ 5 , the expansion amount is about 3.
5 mm, and the S1 is usually 5 mm and the expansion amount is 3.
5 mm is omitted because the left and right frames 4 and the upper and lower frames 5 can be elastically deformed and bent, and S1 is 5 mm to 3.5 mm.
As a result, S1 = 1.5 mm, so that S1 can be reduced to a size of 1/3 or less.
