Abstract
PURPOSE: To make it possible to secure the agreement between the gun axis of an electron gun and the tube axis of a neck and also to prevent the disturbance of the electric field of a main electron lens, by providing a support member which holds the potential of the neck inner wall at a fixed value while making the tube axis agree with the gun axis.
CONSTITUTION: Several electrodes are arranged via insulating support plate 28 and mounted on stem 30. Then, support plate 28 is provided at its fixed position with fitting part 31, via which support member 32 made of a nearly ring-shaped spring is also provided. To convergence electrode 27, getter support spring 34 provided at its middle with convex part 35 is cohered and the contact between this convex part 35 and the conductive coating of the funnel inner wall applies a high voltage to anode- voltage application voltage 26. Support member 32 is arranged nearly touching the neck inner wall and the voltage of the neck inner wall can be held at a desirable level by applying an adequate voltage via stem pin 29 from external power supply 36. As a result, color shading, a shift in color, etc., can be prevented without disturbing the electric field of the main electron lens.
