LENS BARREL AND IMAGE PICKUP APPARATUS

摘要

A retractable lens barrel includes a first main bar, a second main bar, a fixed barrel including the first main bar, a linear movement barrel including a second main bar and movable in an optical axis direction, a leaf spring configured to adjust decentering of the second main bar relative to the first main bar in a plane orthogonal to the optical axis, and leaf springs configured to adjust a tilt of the second main bar relative to the first main bar in the optical axis direction by pushing the linear movement barrel onto the fixed barrel at a plurality of positions in a plane orthogonal to the optical axis. The first main bar and the second main bar are configured to guide a lens frame holding a lens. After the second main bar is moved closer to an object than the first main bar, tilt adjustment by the leaf springs is completed following decentering adjustment by the leaf spring.

主权项

1. A the lens barrel comprising;
a first guide; a second guide configured to protrude toward an object relative to the first guide in an optical axis direction in a transition from a retracted state to a photographing state; a lens holding unit having one holder held by the first guide and another holder held by the second guide; a shift adjuster configured to adjust a shift between the first guide and the second guide in a direction orthogonal to the optical axis in the photographing state; a tilt adjuster configured to adjust a tilt between the first guide and the second guide in the photographing state; and a lock member configured to determine a positional relationship between the first guide and the second guide after the shift adjustment and the tilt adjustment.
