BLUR CORRECTION DEVICE, AND LENS BARREL PROVIDED WITH BLUR CORRECTION DEVICE, AND CAMERA SYSTEM

摘要

A blur correction device according to this disclosure includes: a movable frame which supports a correction optical system, the movable frame having a through hole formed along an optical axis; a base part which holds the movable frame, and a base frame which forms a space, where the movable frame moves, between the base frame and the base part; a guide shaft being disposed inside the through hole formed in the movable frame; a locking member which is movably supported by the guide shaft, the locking member being configured to move into the through hole formed in the movable frame to come into contact with a part of the movable frame for restricting movement of the movable frame in a direction intersecting the optical axis of the movable frame; and a drive unit which drives the locking member along the guide shaft.

主权项

1. A blur correction device comprising:
a movable frame which supports a correction optical system, and is movable in a direction perpendicular to an optical axis of the correction optical system, the movable frame having a through hole formed along the optical axis; a base part which holds the movable frame in a movable state; a base frame which has a facing surface disposed to face the base part, and forms a space, where the movable frame moves, between the base frame and the base part; a guide shaft which has one end side supported on the base part and another end side supported on the base frame, the guide shaft being disposed inside the through hole formed in the movable frame; a locking member which is movably supported by the guide shaft, the locking member being configured to move into the through hole formed in the movable frame to come into contact with a part of the movable frame for restricting movement of the movable frame in a direction intersecting the optical axis of the movable frame; and a drive unit which drives the locking member along the guide shaft.
