A camera capable of stabilizing the open state and closed state of barrier
blades is disclosed. The camera comprises a lens barrel which holds a
lens; and a barrier unit placed closer to the end of the lens barrel than
a flange which is formed on the lens barrel and extends in the direction
orthogonal to the optical axis, wherein the barrier unit has: a barrier
member which opens/closes the front of the lens through a rotation
operation; a barrier driving mechanism which drives the barrier member
according to the operation of the lens barrel; and a partition plate
which separates the barrier member from the barrier driving mechanism in
the direction of the optical axis, and a shaft which supports the barrier
member in a rotatable manner is formed on the flange.
