Document Type and Number:
WIPO Patent Application WO/2020/045630
Kind Code:
A1
Abstract:
The present invention achieves, in a driving device that drives a lens unit and a blade member by one actuator to achieve size and weight reductions of optical equipment, a reduction in the amount of force of the actuator while achieving space saving of the device. This optical member driving device is provided with: a base member which has an opening; a lens unit on which light passing through the opening is incident; a blade member which enters or retreats from the opening; and a slide member by which the blade member is pivotally supported and which slides in a uniaxial direction crossing the optical axis of the lens unit by driving of the actuator, and is further provided with an operation mechanism which operates the lens unit along the optical axis after the blade member is retreated from the opening by sliding of the slide member.
