Latest Patents
Shimada's latest patents include a revolutionary lens barrel design. This invention provides a lens barrel in which all lens groups are attached to a leading cylindrical body. A movable lens group is moved by a driving source incorporated in the leading cylindrical body. This design minimizes the influence of external forces and allows for a more compact structure. The lens barrel consists of first, second, and third cylinders, with the first and third lens groups fixed to the third cylinder. The second lens group is positioned between the first and third lens groups and is movable along the optical axis.
Another notable patent is the lens driving apparatus. This invention prevents the lens barrel from increasing in size and cost while enabling the detection of the position of a movable lens group. The apparatus includes a first lens group, a second lens group, and a third lens group, with the second lens group being movable along the optical axis. A second lens frame holding the second lens group is equipped with a detection plate, allowing for precise position detection of the second lens group.
