Barrier device for camera

A barrier device for a camera having a photographing lens, comprising:

• a cover plate having a first opening through which said photographing lens is selectively exposed;
• a support plate having a second opening positioned coincident with said first opening so that said photographing lens is selectively exposed through said second opening;
• a first barrier member disposed between said cover plate and said support plate, said first barrier member being movable to cover a first part of said first opening;
• a second barrier member disposed between said cover plate and said support plate, said second barrier member being movable to cover a second part of said first opening, said second part not being covered by said first barrier member, such that said second part covers more than half of said first opening;
• an operation member connected to said first barrier member that moves said first barrier member;
• and
• a lever rotatably supported by a rear surface of said support plate, said rear surface of said support plate being positioned opposite to said cover plate, said lever connecting said first barrier member and said second barrier member so that a movement of said first barrier member is transmitted to said second barrier member in such a manner that a moving amount of said second barrier member is greater than a moving amount of said first barrier member.
