Abstract:
1. An image pickup driving apparatus comprising: a transducer for generating an elliptical vibration on a driving section in response to application of a voltage signal of a predetermined frequency; a holding member having a holding section for holding the transducer and an image pickup device; a pressing mechanism arranged on the holding member to press the driving section of the transducer; and a rod-shaped movable body relatively driven by the elliptical vibration of the transducer while being pressed by the pressing mechanism and with a moving direction of the movable body being restricted by a guiding section of the holding member, wherein a weight section is mounted on an end portion of the movable body, wherein the transducer contacts the rod-shaped movable body from a direction vertical to an axis direction of the rod-shaped movable body and the elliptical vibration generated by the transducer is applied to the rod-shaped movable body from the direction vertical to the axis direction of the rod-shaped movable body.
