LENS HOOD DEVICE, AND IMAGE PICKUP DEVICE USING THE SAME

摘要

A lens hood device comprises a barrier case (11) covering the front and back of a lens barrier unit (32) in an optical axis direction and having a non-circular opening at a position passed by the optical axis, and a plurality of lens barriers (14 to 17) arranged turnably in parallel with a main flat face of the barrier case (11) and made turnable 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 so housed in the barrier case (11), when they are positioned to open the opening, as not to be exposed to the opening. The lens hood device provided can improve the operability without enlarging the size of an image pickup device.
