Abstract

PURPOSE: To produce the mark for raster position detection, by locating the raster position index to the position relating to the panel matching point, and by baking the shadow through the through hole around the shadow mask at fluorescent substance film baking.
CONSTITUTION: The shadow mask f is mounted on the pin j at the inner surface of the panel e with the holder 1 of the frame h and a number of beam holes f2 are regularly placed at the effective surface f1, and the raster position index g covers the beam hole of the surface f1. The through hole of the index g is mounted on the exposure stand main body a so that the center of the position index and the panel center are in agreement. When exposure is made after the photosensitive fluorescent film is made in the panel inside, the shadow of the index is not exposed and it can be shown for the mark of the raster position as the part having no fluorescent film. Thus, at the same time when the fluorescent film pattern is baked, the raster position mark can very accurately be adjusted to form, and the performance of the color receiving tube can be increased, by adjusting the raster position for vertical direction by taking this as reference.
