Abstract:
1. A parallel slider device, comprising: a first guide rail and a second guide rail that are disposed parallel to each other; a first slider and a second slider slidably supported by the first and second guide rails, respectively, along a lengthwise direction of the guide rails; a first pneumatic linear guide providing an air gap between the first guide rail and the first slider; a second pneumatic linear guide providing an air gap between the second guide rail and the second slider; a first pneumatic pressure setting device for setting the supplied air pressure of the first pneumatic linear guide at a first value; and a second pneumatic pressure setting device for setting the supplied air pressure of the second pneumatic linear guide at a second value; wherein the first and second sliders are mechanically coupled to each other, and the first and second values are set to be different from each other whereby a slider supporting stiffness of the first pneumatic linear guide is different from that of the second pneumatic linear guide.
