Abstract
Abstract In a drive system of the present invention, a first slider can be moved in first and second directions by movement of first travellers and second travellers. A second slider can be moved in the first and the second directions in a plane which is located away from a plane in which the first slider moves. A third slider can be moved in the second of the first direction on the second slider. Therefore, the first and the third sliders can be synchronously moved despite the plane in which the first slider moves and the plane in which the third slider moves being separated from each other.
