Abstract
PURPOSE: To prevent reduction in the electron beam passing ration cause by attaching of a substance produced from a getter material on the fluorescent screen by providing for an opening of a getter container with a circular shielding plate which opends and shuts the opening depending on temperature.
CONSTITUTION: A circular shielding plate 10 is fixed to a folded edge 112 of a supporting member 11 made of a bimetallic material which is fixed at a side 111 to a getter container fixing end of a spring 6 covering the opening 72 of a getter container 7 at ordinary temperature. As temperature is raised by high-frequency heating from the exterior of a funnel, the supporting member 11 opens so as to allow the circular shielding plate to open so that attaching of the getter material is confined within the funnel area thus preventing attaching of the getter material on the fluorescent screen in the panel area 4.
