Abstract

PURPOSE: To facilitate a ready optical alignment between the fluorescent surface of and the reflecting mirror of a projection type picture tube by installing the reflecting mirror in a glass cylinder inserted and connected between the face plate and a glass enclosure of the picture tube.
CONSTITUTION: A face plate 10 is welded to a glass cylinder 11 by glass solder 12. There are formed a transparent metallic film 19 on the inner surface of the face plate 10 and a fluorescent surface 20 on the predetermined area of the film 19 in a projection type picture tube. A reflecting mirror 15 is temporarily mounted by a screw 16 at an elastic spherical mirror retaining plate 14, and then connected to a pin 13 attached to the inner wall of the cylinder 11. The screw 16 is loosened in this state to then accurately disposed the optical position between the face plate 10 and the mirror 15. After this disposition, the mirror 15 is tightly secured by the screw 16. Thus, the mirror 15 is tightly disposed to the face plate 10, and then welded to a funnel 17.
