Abstract

PURPOSE:To enable to apply a color cathode-ray tube to the exposure of a different deflecting angular panel as well, by arranging a light source moving upward and downward mechanism which makes a light source move upward and downward to the inside surface of a panel face. CONSTITUTION:A state which a movable plate 41 touches the least upper bounding stopper 43 is considered as, for example, the exposing position of a 110 deg. deflecting angular panel 2. When the panel is changed to a different deflecting angular kind, for example, a 90 deg. deflecting angular panel 2 from said state, the movable plate 41 is made to descend to the limit of touching the greatest lower bounding stopper 44 by activating an air cylinder 40. Then, a base 24, a light source portion table 20 and guide rails 45, 46 for drawing out a correcting lens descend together. Thereby, the distance from a light source portion 13 to the inside surface of the face of the panel 2 becomes large, and the exposure of the different kind of a panel can be done.
