摘要
A drive mechanism has an ultrasonic motor having a rotor which is rotationally driven by vibration of a vibrating member having a piezoelectric element. The rotor has a projecting portion for rotation therewith. A driven member is connected to the rotor for undergoing movement along a surface extending in a radial direction of the rotor. A guide member restricts movement of the driven member and guides movement of the receiving member in a given direction. A receiving member contacts the projecting portion of the rotor to limit a range of rotation of the rotor and limit a range of movement of the driven member.
