PURPOSE:To improve reduction of a difference in photostrength at a time of tricolor exposure as well as the relative positional accuracy of a light source and a panel face by connecting a transferer containing a DC servomotor with a means for fixing a panel to a prescribed position and a means for positioning a panel holding table in plural positions for one light source. CONSTITUTION:A moving table 23 held by the guide axes 31a and 31b provided on a box body 26 is connected to a precision feed screw 33 directly connected to a DC digital servomotor 32. Further, when a signal of the value set up by a preseit switch is sent to the DC digital servomotor 32 while being rotated, the moving table 23 moves. A three stage rack with a correction lens holder equipped with the correction lenses corresponding to three colors and correction filters in pairs are guided by a guide axis 43 while being linked to a trapezoidal thread 45 directly connected to a motor 44 for carrying the prescribed correction lens to the position of the moving stand 46. |
