LENS BARREL AND IMAGE PICKUP APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18317256 titled 'LENS BARREL AND IMAGE PICKUP APPARATUS

Simplified Explanation

- The patent application describes a retractable lens barrel design for an optical system. - The lens barrel includes a moving unit that can move a first optical member between an imaging position and a shifted position. - The moving unit is supported by a base member, and there is a cylindrical member and an operating member involved in the design. - When the operating member is operated, it causes relative movement between the cylindrical member and the base member. - The cylindrical member has a sliding surface on which the moving unit slides, and it also has an engagement portion. - As the lens barrel transitions from the imaging state to the retracted state, the moving unit slides on the sliding surface and moves the first optical member from the imaging position to the retracted position. - In the retracted state, the moving unit is engaged with the engagement portion of the cylindrical member, restricting its movement.


Original Abstract Submitted

A retractable lens barrel includes a moving unit configured to move a first optical member in an optical system between an imaging position located on an optical axis and a shifted position shifted from the optical axis, a base member movably supporting the moving unit, a cylindrical member, and an operating member configured, when operated, to cause relative movement between the cylindrical member and the base member. The cylindrical member includes a sliding surface on which the moving unit slides and an engagement portion. The moving unit slides on the sliding surface and moves the first optical member from the imaging position to the retracted position as the lens barrel transitions from the imaging state to the retracted state. In a case where the lens barrel is in the retracted state, the moving unit is engaged with the engagement portion and restricted from moving.
