摘要： An ultrasonic motor, comprises an annular stator including an elastic member and piezo-electric elements secured to said elastic member which generate a travelling wave on the surface of the elastic member by being applied with high frequency voltages; and a rotor which is in pressure-contact with the elastic member and is driven to be rotated with respect to said stator by the travelling wave. The rotor includes a cylindrical main body and a thin radial flange integrally secured to the periphery of the rotor main body at one end of the main body facing the stator, and a cylindrical vibration portion secured to a periphery of the flange having a diameter different from that of the rotor main body. The vibration portion extends in a direction which is the same as the vibration direction of the travelling wave. The rotor satisfies the following relation 5

摘要： Provided are a driving apparatus and an imaging device having the driving apparatus mounted thereon, the driving apparatus being capable of performing, with a simple configuration, driving in the Z-axis direction in addition to driving in a direction along the XY plane, reducing friction at the time of driving, and performing precise position holding at the time of stop. A driving apparatus includes: a frame, a contact body supported by the frame; a holder pressed against the contact body to be supported thereby; a VCM for relatively moving the frame in a direction along a support plane formed by the contact body; and a transducer for displacing, relative to the frame, the contact body in the Z-axis direction. When driving, the transducer causes the contact body to vibrate in the Z-axis direction so as to reduce a frictional force between the contact body and the holder.

摘要： A dust-screening member is shaped like a plate as a whole. A vibrating member is adjacent to one side of the dust-screening member and arranged on the surface along the one side. A drive unit is configured to drive the vibrating member to produce a vibration having a vibrational amplitude perpendicular to the surface, on the surface, such that peak ridges of the vibration form a closed loop and an area including a center of the closed loop surrounded by a node area having almost no vibrational amplitude. When a length of a side in a dust-screening member virtual rectangle corresponding to a short side of a vibrating member virtual rectangle is assumed to be LFw, and a length of short side of the vibrating member virtual rectangle is assumed to be WE, WF/LFw has a dimension of 0.095 or greater and 0.105 or less.
