TELEVISION IMAGE PROJECTOR

摘要

PURPOSE:To improve the assembling performance while to reduce the cost by providing a rectangular flange section on the outercircumferential face while employing rectangular rear face section of same dimension with the image to produce a projection lens then fixing said lens through a frame body in front of an image tube. CONSTITUTION:A projection lens 22 is arranged in front of the front glass board 21 of image tube 20 to project a magnified image onto a screen. In such television image projector, the lens element 23 nearest to the image tube 20 of projection lens 22is provided with rectangular flange section 23a on the outercircumferential face while the rear face section 23e is made rectangular with approximately same size with the image. The flange section 23a is adhered through a rectangular frame body 24 to the front glass board 21 while silicon gel 25 is filled in a space surrounded by the frame body 24. Consequently, it can be assembled easily with high tightness while the cost can be reduced through simplification of the frame body 24.
