ABSTRACT:
A filtering arrangement for adjusting the color composition of the copying light in a color copier has three filters located upstream of an original to be copied as considered in the direction of light propagation. Each filter is divided into three filter sections which are rotatable in unison so as to project into the path of the copying light to larger or smaller degrees. A motor is provided for each filter and each motor has a rotatable drive shaft which is parallel to the path of the copying light. One of the filter sections of each filter is fixedly mounted on the shaft of the corresponding motor for rotation therewith. The remaining two filter sections of each filter are mounted on the shafts of the other motors via roller bearings so as to be rotatable relative to such shafts. The three filter sections of each filter are connected by a cable so that all three filter sections rotate when the motor corresponding to the filter is actuated. By mounting the filter sections of one filter on the drive shafts of the motors for the other filters, the number of pivots required for the filtering arrangement is reduced.
