Abstract

PURPOSE:To improve the hole shape of the exposure surface to a circular shape, by enabling a lamp house accommodating a lamp acting as a light source to make reciprocating motion in the axial direction of the color picture tube. CONSTITUTION:An extra-high pressure mercury lamp or the like to which sensitive slurry on the inner surface of a panel is exposed is accommodated in a lamp house 10. Then, the lamp house 10 can be arranged to make reciprocating motion in the direction of the tube axis of a color picture tube by moving slide spindles 102 and guide spindles 103 upward and downward by rotating an eccentric cam 101 with a motor 100. Thereby, as the light source can have a certain dimension in the direction of its motion, the hole shape of an exposure surface is improved to a circular shape from an eliptic shape.
