ABSTRACT:
When a toggle-like latch is pivoted to release a shutter opening blade for movement from its cocked position to open the camera shutter, a resiliently flexible member of the latch engages a shutter closing blade to retain the closing blade in its cocked position. A camming surface is arranged on the opening blade to bend the flexible member out of engagement with the closing blade to release the closing blade for movement to close the camera shutter. The camming surface bends the flexible member to release the closing blade as the opening blade is moved to at least partially open the camera shutter.
