To provide an X-Y table device, restraining the generation of a dead space to have good space efficiency and reduce the size.

The rotation of a cam member 12 is converted to linear motion in the lateral direction (the direction of a first axis) and in the longitudinal direction (the direction of a second axis) by a first converting mechanism 13 and a second converting mechanism 14, and synthesized by a synthesizing mechanism 15 to generate plane motion (circular motion). The first converting mechanism 13, the second converting mechanism 14, the synthesizing mechanism 5 and a table member 16 are disposed to surround the peripheral edge part of the cam member 12, so that the device can be made compact as a whole.
