Lens device










Image Number 9 for United States Patent #7480104.

A lens device includes a base unit, a rotatable barrel component, a press plate, and a lens unit. The base unit includes a base plate, and a stationary barrel component connected to the base plate and extending there from a long an axis. The rotatable barrel component is sleeved rotatably on the stationary barrel component. The press plate has at least one fixing end portion secured to the base unit, and a press section connected to the fixing end portion. The press section is elastically deformable relative to the fixing end portion and is disposed to abut against an annular outer surface of the rotatable barrel component to resist axial movement of the rotatable barrel component. The lens unit is driven to move relative to the base unit along the axis upon rotation of the rotatable barrel component.
