Abstract
PURPOSE:To make the construction of the apparatus simple and improve its reliability by performing the adjustment of color balance of separated light of three colors through the change in the applied voltage on an exposure lamp and performing the adjustment of overall brightness through the change in the stopping amount of the stop plates provided within the optical path. CONSTITUTION:In order to adjust the color balance of separated light of three colors, the voltage of the values adjusted by lamp voltage adjusting parts 4A, 4B, 4C in correspondence to the respective colors of three-color separating filters is applied to an exposure lamp 1 by way of a lamp voltage control part 7. At the time of exposure, the color separating filters turn to the position of crossing the optical path and every time when they stop, switches A, B, C go ON subsequently. In order to adjust the overall brightness, the optical path is shielded in correspondence to each filter by the stop plates 13 having stopping amounts differing in correspondence to the respective filters. Thereby, the construction of the apparatus is made simple and its reliability improved.
