Abstract
Provided is a lens driving apparatus, including: an ultrasonic motor including a drive slider having an output shaft provided so as to project in a direction perpendicular to a driving direction of the drive slider; a lens moving frame configured to hold an optical system, and having a hole into which the output shaft is to be inserted; and a fixed portion configured to support the lens moving frame so that the lens moving frame is movable in a direction perpendicular to an optical axis, hold the ultrasonic motor so that the ultrasonic motor is removable from a side opposite to a side where the lens moving frame is provided, and have a through hole passing through the fixed portion in a direction of the optical axis.
Claims8
A lens driving apparatus, comprising:
- an ultrasonic motor including a drive slider having an output shaft provided so as to project in a direction perpendicular to a driving direction of the drive slider;
- a lens moving frame configured to hold an optical system, and having a hole into which the output shaft is to be inserted;
- and
- a fixed portion configured to support the lens moving frame so that the lens moving frame is movable in a direction perpendicular to an optical axis, hold the ultrasonic motor so that the ultrasonic motor is removable from a side opposite to a side where the lens moving frame is provided, and have a through hole passing through the fixed portion in a direction of the optical axis.
An image blur correction apparatus, comprising a lens driving apparatus, the lens driving apparatus comprising:
- an ultrasonic motor including a drive slider having an output shaft provided so as to project in a direction perpendicular to a driving direction of the drive slider;
- a lens moving frame configured to hold an optical system, and having a hole into which the output shaft is to be inserted;
- and
- a fixed portion configured to support the lens moving frame so that the lens moving frame is movable in a direction perpendicular to an optical axis, hold the ultrasonic motor so that the ultrasonic motor is removable from a side opposite to a side where the lens moving frame is provided, and have a through hole passing through the fixed portion in a direction of the optical axis.
An image pickup apparatus, comprising:
- a lens driving apparatus comprising:
- an ultrasonic motor including a drive slider having an output shaft provided so as to project in a direction perpendicular to a driving direction of the drive slider;
- a lens moving frame configured to hold an optical system, and having a hole into which the output shaft is to be inserted;
- and
- a fixed portion configured to support the lens moving frame so that the lens moving frame is movable in a direction perpendicular to an optical axis, hold the ultrasonic motor so that the ultrasonic motor is removable from a side opposite to a side where the lens moving frame is provided, and have a through hole passing through the fixed portion in a direction of the optical axis;
- and
- an image pickup element configured to receive light from the optical system.
