Abstract

PURPOSE:To lessen space loss of a tube, by both constituting an envelope from a panel, shadow mask mounting frame and funnel and fixedly tightening a long hole in a side of the mask to a screw embedded to an inner wall of the mounting frame with a nut. CONSTITUTION:The envelope of a picture tube is divided into three parts and constituted from a panel 2, shadow mask mounting frame 11 and funnel 4. A mounting seat 13 with a screw is embedded to the shadow mask mounting frame 11 and correspondingly place to a long hole 3a in a shadow mask 3, then the shadow mask 3 is directly fixed to the mounting frame 11 with a washer and nut. In this way, position relation between the panel and the shadow mask can be correctly obtained to prepare the color picture tube with a less space loss.
