ABSTRACT:
A cartridge changer having a predetermined width across a predetermined rotational plane, includes a rack being rotatable and storing at least first and second cartridges in a predetermined rotational plane, wherein at least one distance extending across the first and second cartridges in the predetermined rotational plane and through a rotational axis of the rack is greater than the predetermined width of the cartridge changer, and a rotator for rotating the rack in the predetermined rotational plane, so as to exchange a position of the first and second cartridges within the rotational plane without exceeding the predetermined width of the cartridge changer. The rotator more specifically performs a combination of rotation and shifting of the first and second cartridges with respect to one another within the rotational plane to accomplish exchange of the first and second cartridges within the rotational plane without exceeding the predetermined width of the cartridge changer. The shifting is more specifically linear displacement of the first and second cartridges in a direction parallel to a diameter defined in the predetermined rotational plane and through the rotational axis of the rack, and wherein an amount of linear displacement of the first and second cartridges at any given point of rotation is dependent on an amount of angular displacement of the rack from a predetermined position.
