  • Patent number: 6669381
    Abstract: Disclosed herein is a camera having a shutter mechanism; actuating means for actuating the shutter mechanism; and, an aperture selecting assembly that is movable from an initial mode position to at least a first mode position. Also disclosed is an aperture selector assembly that is coupled to the shutter actuating mechanism and includes a slide that is selectively movable from an initial mode position to one of a plurality of aperture selecting positions. During slide movement to the desired aperture setting, the strobe is energized and the energy to operate the shutter is stored in a spring. At the desired position, the selector slide is detented by a first clasping device until a shutter button is actuated for releasing the shutter and firing the strobe. A second clasping device becomes operative during shutter actuation to hold the slide in position even though the detent of the first clasping device has been released.

  • Patent number: 6173126
    Abstract: An improved camera comprising a strobe circuit, a strobe, a shutter mechanism and an actuating mechanism are disclosed. A finger engageable portion of the shutter mechanism operates the shutter. A shield is movable between a first blocking position for blocking the finger portion against engagement to prevent accidental actuation of the shutter mechanism and a second position exposing the finger portion of engagement to actuate the shutter. An assembly operatively interconnecting the shield and the strobe circuit to energize the strobe circuit when the shield is in the second position.

  • Patent number: 6099172
    Abstract: A simplified camera mechanism and method for allowing an operator to select distinct ones of several apertures by actuation of a finger engageable aperture selector as well as insure return of the selector to an initial mode position as a shutter actuator assembly returns to its original unactuated position following release thereof by the operator.
