ABSTRACT:
Apparatus for pivoting a shutter or a filter between two end positions in a photographic copying machine has two magnetic systems one of which moves the shutter or filter during the last stage of movement from one to the other end position and thereupon holds the shutter or filter in the selected end position. The other magnetic system initiates the movement of shutter or filter from the one to the other end position and accelerates it during movement to a neutral position midway between the two end positions. The other system is deactivated while the shutter or filter moves between the neutral and other end positions. Each system can include an electromagnet. Alternatively, the other system employs two electromagnets and the one system then uses a permanent magnet which shares the movements of the shutter or filter.
