ABSTRACT:
A locating table apparatus according to the present invention is provided with a housing, a base member fixed in the housing, a table mounted so as to freely move in a longitudinal direction, driving members located on the base member for supporting and driving the table, and a plurality of electrostatic dust absorbing members arranged at predetermined positions in the housing via respective electrical insulative members, wherein the electrostatic dust absorbing members provide a parallel plate-shaped condenser. Further, the locating table apparatus may provide a dust counter for monitoring the dust density at predetermined positions outside the housing, a device for operating the electrostatic dust absorbing members when the monitored dust density exceeds a warning level, and a device for forcing the motor to stop in response to a level of a signal detected by the dust counter.
