LENS HOOD DEVICE, AND IMAGE PICKUP DEVICE USING THE SAME

摘要

A lens hood device includes a barrier case (11) to cover the front and back of a lens barrier unit (32) in an optical axis direction and to have a non-circular opening at a position passed by the optical axis, and a plurality of lens barriers (14 to 17) arranged rotatably in parallel with respect to a main plane of the barrier case (11) and made rotatable between a position to cover the whole face of the opening and a position to open the opening. The lens barriers (14 to 17) are contained in the barrier case (11) in order not to be exposed at the opening, when they are positioned to open the opening. The thus provided lens hood device can improve the operability without enlarging the size of an image pickup device.
