ABSTRACT:
A shutter mechanism comprising a shutter blade supported to move open and closed, a shutter actuator having an actuating striker and supported for movement to cause the actuating striker to strike the shutter blade to move the shutter blade open and for movement to be re-cocked, and a closing spring for moving the shutter blade closed, is characterized in that the shutter actuator is supported for unidirectional movement to cause the actuating striker to strike the shutter blade to move the shutter blade open and is supported to undergo a different direction of movement to move the actuating striker out of the way of the shutter blade to permit the shutter blade to be moved closed and to prevent the shutter blade from obstructing the actuating striker when the shutter actuator is re-cocked, and a guide device controls movement of the shutter actuator to effect the unidirectional movement and the different direction of movement of the shutter actuator.
