In order to transfer a magazine from a depositing position to a processing station, a linear drive for a rigid gripper arm is attached to a supporting column, an air passage opening being formed by the space between the supporting column and an elevator drive, this linear drive being vertically adjustable in the movement direction of the elevator. The range of action of the gripper arm is located above the magazine in the depositing position and is directed vertically to the movement direction of the elevator. All drive parts are separated from the clean room by a dust-tight enclosure and suction devices are arranged adjacent to openings through which the transport elements project into the clean room.
