The present invention relates to a two dimentional drive system. The drive system comprises a pair of guides provided on a base, the guides arranged in parallel in the X-direction; a rod arranged in the Y-direction, each end of the rod being slidably attached to the guides. A moving body is capable of moving on the rod. A first motor, which has a first shaft, is provided for rotating the first shaft. The first motor is provided to the base. A second motor, which has a second shaft, is provided for rotating the second shaft, the second motor is provided to the moving body. A first link includes a first end and a second end, the first end of the first link is connected to the first shaft. A second link includes a first end and a second end. The first end of the second link is connected to the second shaft. The second end of the second link is rotatably connected to the second end of the first link. In the present invention, the drive system has no ball bearing screws, so that the manufacturing cost and noise during operation can be lower.
