Claims

[Scope of Claim for Utility Model Registration] A shutter that has a light shielding part at one end and an operating part that receives rotational force at the other end, and rotates around a shaft to open and close a photographing optical path with the light shielding part; a spring that biases the shutter in the closing direction; and a moving member that has a drive section that acts on the operating section and rotates the shutter in the opening direction in the process of returning from the set position to the rest position in conjunction with the release operation. A shutter device comprising: a locking portion on the actuating portion that prevents the shutter from rotating in the opening direction when the movable member is in the set position. Device.
