Abstract

PURPOSE: To provide a picture of high quality, with a mounting precision enhanced of the electron gun, by applying the electron gun having more than two pairs of light penetrable holes in top and bottom of the electrode wall.
CONSTITUTION: At the side wall of a cover cup 28, uppermost part of an electron gun 13, and of a third electrode 29, cup-shape electrode in lowermost, is provided a light penetrable hole 30a, 30b respectively. The light penetrable hole 30a, 30b is constructed in a manner with a light beam axis, passing through said hole, so as to be along the direction of arrangement of three axes of the electron gun. With a light projected to the light penetrable hole 30a, 30b constructed in the electron gun 13 inserted into the neck portion, as well as with the light, passing through the light penetrable hole 30a, 30b, received, the positioning work is performed by a picture magnified by a monitor television.
