Patent ID: 7927029

Claim:
An imaging apparatus comprising: a lens; a first blade slidable between a first blade covering position where the first blade covers a portion of a front side of the lens and a first blade retract position where the first blade retracts from the portion of the front side of the lens to uncover the portion of the front side of the lens; and a second blade pivotally supported by the first blade and movable between a second blade covering position where the second blade covers a remaining portion of the front side of the lens and a second blade retract position where the second blade retracts from the remaining portion of the front side of the lens to uncover the remaining portion of the front side of the lens, wherein the first blade does not rotate but linearly slides to and between the first blade covering position and the first blade retract position and, as the first blade moves from the first blade retract position to the first blade covering position, the second blade moves linearly with the first blade and pivots relative to the first blade to move from the second blade retract position to the second blade covering position.
