ABSTRACT:
A color copying apparatus wherein a copy carrier sheet is attracted by the suction chamber of a carriage which is reciprocable along a horizontal path past an exposure station and along a battery of aligned developing units. After each exposure with a different filter, the sheet is moved into register with a different developing unit. The carriage is moved by an endless belt which has a pin receivable in one of two vertical slots on a plate-like female coupling member of the carriage. Guide rollers automatically disengage the pin from the coupling member when the carriage reaches the exposure station. The suction chamber is then attracted by electromagnets so that two sockets of the suction chamber move downwardly and receive stationary centering pins which hold the carrier in a predetermined position during each of a series of exposures. This insures accurage register of successively projected and developed images in the three basic colors.
