Driving method

Abstract

A method for driving a movable component of a hardware device to move a driving distance includes the steps of: (1) adjusting at least one of the former time and the latter time according to an advancing time so that a sum of the former time and the latter time is substantially equal to the advancing time; and (2) driving the movable component to the driving distance by the former force for the former time and by the latter force for the latter time.
