を特徴とする投写用陰極線管装置。 An image drawn on a fluorescent surface formed on the inner surface of a face plate of a projection cathode ray tube is projected onto a projection screen via an optical system including a lens having an opposing surface substantially parallel to the outer surface of the face plate. In a projection cathode ray tube device adapted to perform enlarged projection, a biconvex lens-shaped optical cup made of an elastic body is provided between the outer surface of the face plate and the opposing surface substantially parallel to the outer surface of the face plate. A cathode ray tube device for projection, characterized in that a ring member is crimped and fixed.
