Abstract
A driving device includes a driving motor, a first gear-, and a gear-having a smaller diameter than the gear-. Driving force from the driving motor is transmittable to a driven object when the gear-moves in an axial direction of a rotation shaft to be coupled to the gear-. When the gear-moves in the axial direction to be decoupled from the gear-, the driving force from the driving motor can be prevented from being transmitted to the driven object.
