  • Aperture mechanism having a blade positionable in an open position by a hard stop
    Patent number: 5432576
    Abstract: An aperture mechanism includes at least one blade moveable along a path between a closed position and at least one open position. At least one hard stop is moveable between a first position, out of the blade path, and a second position in the blade path to position the blade in the open position when an edge of the blade contacts the hard stop. The hard stop is located out of a plane of movement of the blade when the hard stop is in the first position to simplify and make more accurate the positioning of the blade in the open position.

  • Camera mechanism for setting focus and aperture
    Patent number: 5311239
    Abstract: A fast-opening shutter includes an actuating member moveable in a one direction for setting an aperture stop and in the opposite direction for setting focus. The camera shutter is then driven to open against the stop independently of movement of the actuating member. According to more specific features, the actuating member first sets the stop and then focuses a camera optical element. After the exposure is completed, the mechanism is reset by further movement of the actuating member in the second or opposite direction.
