Claim:
1. A linear movement device comprising: at least two linear movement units guided in movement along a shared linear movement axis; a first linear drive; and a second linear drive; wherein each of the at least two linear movement units can be driven in movement along the linear movement axis by at least one of the first linear drive and the second linear drive; wherein the first and the second linear drives are coupled to the at least first and second linear movement units so as to transmit drive force so that when only one of the first linear drive and the second linear drive is activated, the at least two linear movement units can be driven in movement in a shared direction along the linear movement axis at different speeds, and when the first and the second linear drives are activated simultaneously, all of the at least two linear movement units can be driven at least in joint movement in the same direction along the linear movement axis at a same speed.
