Abstract
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.

A camera comprising:
- 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.
An optical apparatus comprising;
- a lens;
- and
- a lens barrel which holds the lens;
- wherein
- the lens barrel having in order from an object side
- a barrier member which rotates around a first shaft and opens/closes the front of the lens;
- a partition plate;
- and
- a barrier driving member which drives the barrier member through a second shaft, and the first shaft is united with the lens barrel.
