IMAGING APPARATUS

摘要

An imaging apparatus includes a movable member supporting an imaging device; a stationary member supporting the movable member to allow the movable member to spherically swing about a point on an optical axis of the imaging device; first and second actuators which apply two driving forces to the movable member in different tilting directions to vary an inclination of the optical axis; and a third actuator which applies a driving force to the movable member in a rotational direction about the optical axis. The first, second and third actuators are provided as three separate actuators installed at intervals in a circumferential direction about the optical axis, in an initial state of the movable member in the spherical-swinging operation relative to the stationary member. Part of each of the first, second and third actuators lies on a cylindrical surface centered on the optical axis in the initial state.

1. An imaging apparatus comprising:
a movable member configured to support at least a part of an imaging device, for obtaining object images; a stationary member configured to support said movable member in a manner to allow said movable member to spherically swing about a predetermined point on an optical axis of an optical system of said imaging device; a first actuator and a second actuator which apply two driving forces to said movable member in different tilting directions to vary an inclination of said optical axis; and a third actuator which applies a driving force to said movable member in a rotational direction about said optical axis, wherein said first actuator, said second actuator and said third actuator are provided as three separate actuators installed at intervals in a circumferential direction about said optical axis, in an initial state in which said movable member is positioned at an initial position in said spherical-swinging operation with respect to said stationary member, and wherein part of each of said first actuator, said second actuator and said third actuator lies on a cylindrical surface centered on said optical axis in said initial state.
