Abstract
A driving apparatus comprises: an electro-mechanical conversion element; a driving member that drives backwards and forwards in a straight line in response to extension and contraction of the electro-mechanical conversion element which are brought about by a drive signal being supplied thereto; a driven member, frictionally engaged with the driving member, that moves backwards and forwards in a straight line along the driving member by driving the driving member; and a drive control unit that divides a whole traveling area of one or both of an outgoing traveling path and an incoming traveling path of the driven member into a plurality of divided areas and supplies different drive signals to the divided areas so as to implement a drive control.
