AI Technical Summary

Technical Problem

Existing image stabilization devices in imaging devices are limited to translational movement and lack a configuration that can effectively restrict both translational and rotational movement of the movable part while minimizing outward protrusion, especially for correcting 'walking blur' which requires significant rotational movement.

Method used

An imaging device with a movable part capable of both translational and rotational movement, utilizing a first and second actuator to generate forces in parallel directions, and a restricting mechanism using holes and protrusions to control movement within a defined plane, with rolling members to minimize protrusion.

Benefits of technology

The solution effectively restricts both translational and rotational movements of the movable part, reducing outward protrusion and enhancing blur correction capabilities, particularly for 'walking blur', while maintaining a compact device size.

Abstract

The movement of the movable part, which is movable in a plane relative to the fixed part, is appropriately restricted. [Solution] The first image stabilization unit 20 of the imaging device 10 includes a first restricting means and a second restricting means that restrict the movement of a movable part 20b that can translate and rotate in a plane relative to a fixed part 20a, and three balls 36 sandwiched between the fixed part 20a and the movable part 20b. At least a portion of the first restricting means is positioned within a region formed by a straight line connecting the three balls 36, while the second restricting means is not positioned within that region. The first restricting means has a first hole and a second hole on one of the fixed part 20a and the movable part 20b, and a contact portion 38a that is inserted into the first hole and the second hole on the other. When viewed from a direction perpendicular to the plane in which the movable part 20b can translate, the first hole is located on a straight line parallel to the first direction in which the movable part 20b can translate, passing through at least a portion of the second hole.
