a drive device includes a base and a driven member placed on the base . the driven member is capable of rotation on the base and has a circular surface following the direction of rotation . a roller member contacts the outside or inside of the circular surface of the driven member and is supported to be capable of rotation together with the driven member . a vibration actuator contacts the roller member and drives the roller member to rotate . a pressing member presses the vibration actuator in a direction substantially perpendicular to the axis of rotation of the driven member . the pressing member presses the vibration actuator against the roller member , which in turn is pressed against the driven member .
