ABSTRACT:
A camera comprises an exposure aperture, a shutter blade supported for pivotal movement from a covering position over the exposure aperture to an uncovering position removed from the exposure aperture and having an indentation along an edge of the shutter blade, and a striker movable within the indentation in a forward direction against one portion of the edge to pivot the shutter blade from its covering position to its uncovering position. The striker is movable in the forward direction out of the indentation when the shutter blade is pivoted to its uncovering position, in order to allow the shutter blade to be returned to its covering position, and is movable in a reverse direction to return to the indentation when the shutter blade is in its covering position. Another portion of the edge faces the one portion of the edge within the indentation to contact the striker in the indentation, in order to prevent the shutter blade from being dislodged from its covering position due to a physical shock to the shutter blade.
