摘要： The focal-plane shutter includes a blade drive member, an acceleration member providing a driving force to the drive member, and a lock member reducing bounce of the drive member after blade movement completion and being movable between a first position where a stopper portion thereof enters a movable area of a contact portion of the drive member and a second position where the stopper portion is located outside the movable area. During the blade movement, the contact portion pushes the lock member to move it from the first to second position. Before the blade movement completion, the contact portion is away from the lock member and thereby the lock member is moved from the second to first position by a biasing force. After the completion, the acceleration member pushes the lock member to move it from the first to second position.
