IMAGING APPARATUS

摘要

An imaging apparatus includes a front lens group, including a reflector element and a front lens element on the object side thereof, and a rear lens group; a support member, fixed to a fixed member that supports the reflector element, including a spherical-swinging operation support positioned behind the reflection surface of the reflector element and supporting a movable member supporting the front lens element to spherically swing about a predetermined point, a rotation preventer preventing the movable member from rotating about the optical axis of the front lens element, a detector supporter, and a mounting portion mounted to the fixed member; an actuator which drives the movable member to spherically swing the movable member in response to vibrations applied to the imaging optical system; a detector detecting positional variations of the movable member; and an adjuster which adjusts the position of the mounting portion relative to the fixed member.

主权项

1. An imaging apparatus comprising:
a front lens group which constitutes part of an imaging optical system of said imaging apparatus and includes a reflector element and at least one front lens element, which is positioned on the object side of said reflector element, wherein said reflector element includes a reflection surface which reflects light rays, incident from the object side, in a different direction; a rear lens group which constitutes another part of said imaging optical system and is positioned on the image side of said front lens group; a movable member which supports said front lens element; a fixed member which supports at least said reflector element; a support member which is fixed to said fixed member and supports said movable member to allow said movable member to spherically swing about a predetermined point, positioned behind said reflection surface with respect to a direction along an optical axis of said front lens element; an actuator which applies a driving force to said movable member to spherically swing said movable member about said predetermined point in response to vibrations applied to said imaging optical system; and a detector which detects positional variations of said movable member when said movable member spherically swings about said predetermined point, wherein said support member includes a spherical-swinging operation support which is positioned behind said reflection surface in said direction along said optical axis of said front lens element and supports a supported portion of said movable member to allow said movable member to spherically swing about said predetermined point; a rotation preventer which prevents said movable member from rotating about said optical axis of said front lens element; a detector supporter which supports said detector; and a mounting portion which is mounted to said fixed member, and wherein said imaging apparatus further includes an adjuster which enables said mounting portion to be positionally adjusted relative to said fixed member.
