Abstract
A motor for a focus fine tuning lens is attached to the side of a lens barrel. The motor connects to a lens holding frame of the fine tuning lens via a belt, so that the backlash can be prevented. Because the motor and a belt transmission mechanism are accommodated by a drive unit, the existing drive unit can be used without changing its size and form.
