  • Patent number: 11831970
    Abstract: An image pickup apparatus is capable of decreasing a space capacity occupied by component elements and being downsized compared to a case where an actuator is arranged independently of a supporting unit. The image pickup apparatus has an image pickup unit driven by the actuator, a base unit, and the supporting unit provided in a standing manner from the base unit and rotatably supports the image pickup unit. The actuator has a piezoelectric element and an oscillator including a transmission unit which transmits driving force caused by vibration excited by the piezoelectric element. The transmission unit is arranged in the supporting unit so that it is in pressure contact with the image pickup unit. The image pickup unit has a transmitted plane with which the transmission unit is brought into pressure contact, and the vibration excited by the oscillator causes the transmitted plane to move relatively to the oscillator.

  • Patent number: 11516407
    Abstract: A vibration driving device that achieves low cost and high accuracy while reducing driving load. A drive unit has a vibrator with a projection and generates driving force by vibrating the vibrator. A first unit has a contact portion with which the projection is in pressure contact in a first direction. A second unit rotates relative to the first unit around a rotation axis parallel to the first direction by the driving force. Three or more support members are between the first and second units in the first direction to support the first and second units rotatably. The support members are positioned such that, during relative rotation of the first and second units, a contact point at which the projection contacts the contact portion is always located in at least one of triangular areas formed by connecting any three support members with straight lines when viewed in the first direction.
