Claim Text:
1. A lithography apparatus that includes a plurality of driving units which include a first driving unit and a second driving unit different from the first driving unit, driving in synchronization to each other within a synchronization period and driving in asynchronization to each other within an asynchronization period, the lithography apparatus comprising: a plurality of capacitors which include a first capacitor capable of charging power to drive the first driving unit and a second capacitor capable of charging power to drive the second driving unit; a power source configured to supply power required for driving to each of the plurality of driving units and for charging power to each of the plurality of capacitors; a plurality of switching units respectively switching whether or not the power is supplied from the power source to each of the plurality of driving units and each of the plurality of capacitors; and a controller configured to control switching of the plurality of switching units, wherein the controller is configured to control the switching to cause the power source to stop supplying the power to the first driving unit and the first capacitor, and to cause the first driving unit to drive with the power charged in the first capacitor, in at least a part of the synchronization period and to control the switching to cause the power source to stop supplying the power to the second driving unit and the second capacitor and to cause the second driving unit to drive with the power charged in the second capacitor, in at least a part of the asynchronization period.
