Abstract

PURPOSE: To enable the automatic setting of the positions of interference filters by storing the respective positions of the interference filters determined according respective standard negative films in an electric circuit for servomechanism and having the servomechanism that can instruct the movement of the interference filters.
CONSTITUTION: A block 22 consists of a color correcting reference voltage part of a printing light source, a block 23 of an interference filter position detecting part, and a block 24 a differential amplifier part. A block 25 is a comparing part and this device is consisted of these four blocks. A servomotor 45 is inverted of its rotating direction by the positive and negative of the applied voltage and is set in such a rotating direction as to make V2=V1. If color correction of the printing light source is made beforehand for every negative of 3 kinds by variable resistors 26, 27, 28, the desired color correction is made possible only by the operation of a change-over switch 29.
