<p><P>PROBLEM TO BE SOLVED: To provide a moving device which allows a plurality of translation mechanisms that move involving heat generation to have extended service life under thermal degradation. <P>SOLUTION: When the temperature margin of one of the plurality of translation mechanisms (electric motors 31R and 31L) is larger than that of the other translation mechanism, the operation mode of the plurality of translation mechanisms is controlled so that the amount of heat generated from the one translation mechanism is larger than that from the other translation mechanism. This reduces the temperature margin difference between the plurality of translation mechanisms. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
