Abstract:
1. A lens barrel comprising: an image pickup optical system comprising a plurality of lenses transmitting a light flux from a subject; an image converting the pickup light flux element from the for photo-electrically subject transmitted by the image pickup optical system; a plurality of reflection members including first to n-th reflection members in order from the subject, the first reflection member being arranged at a position to bend an optical path of an incident light flux to enter the image pickup optical system, a (n−1)-th reflection member being arranged at a position to bend an optical path in a direction in a plane perpendicular to the optical path of the incident light flux, the n-th reflection member being arranged at a position closest to an image plane of the image pickup optical system to bend an optical path in a direction parallel to the optical path of the incident light flux; and an actuator for moving the image pickup element in a plane perpendicular to an optical path bent by the n-th reflection member for stabilizing an image, wherein the n-th reflection member and the image pickup element move in a direction parallel to an optical path bent by the (n−1)-th reflection member for an adjustment of a focal point of the image pickup optical system.
