ABSTRACT:
A driving apparatus includes a stepping motor having a lead screw, a rack, and a rack-retaining bar, a barrel, a barrel-retaining bar, and a connecting spring for connecting the rack to the barrel. The connecting spring includes an engaging portion that engages with a spherical output member of the rack. The stepping motor in which the lead screw and the rack are integrated with each other and the barrel are connected to each other with provides a structure that absorbs relative positioning error and backlash.
