Abstract
PURPOSE: To make it possible to manufacture a color picture tube with constant- width gaps of light-absorptive stripes, by varying the light-source exposure length of a color-picture-tube manufacturing exposure unit according to the swinging of the light source and by correcting the illumination variation due to the variation in exposure length.
CONSTITUTION: On base mount 3, a panel to be exposed is placed and then exposed to light source 4 supported by swinging base mount 5 an its bottom. Light source 4 adjusts the exposure length matching with the swinging so that it will be short at the time of center exposure of panel 1 and long at the time of circumference exposure. Dimmer 7 corrects the illumination variation attending upon this exposure-length variation. Slit 11 crosses the axis of light source 4 at right angles and is reciprocated interlocking with the swinging.
