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.
