Abstract: A photographic apparatus particularly suitable for the exposure and initiation of processing of a self-processing film unit includes a movable shuttle that is adapted to engage the film unit and advance the exposed film unit at least partially from its exposure position. A spring biases the shuttle towards a retracted position wherein a film engaging portion thereof is disposed to engage the film unit in its exposure position. After advancement of a foremost film unit from the exposure position a restraint supports the shuttle in an advanced position against the bias of the spring. The shuttle is releasable from the restraint in response to movement of a body release from an initial position to initiate exposure of the next succeeding film unit.

Abstract: A camera adapted to make exposures of a scene illuminated by substantially constant or transient (flash) light includes exposure control apparatus having a photosensor to effect an exposure of duration related to the intensity of the light, a focus control and first and second light attenuating elements mounted to be selectively positioned in and out of the optical path of the photosensor. The attenuating elements are biased to move toward the optical path; and for exposures in substantially constant light, the first attenuating element is held out of the optical path. For exposures in flash light, the first attenuating element is positioned within the optical path while the second attenuating element is moved out of the optical path while the second attenuating element is released to move into the optical path to an extent determined by the focus control.

Abstract: A self-releasing pawl and ratchet clutch is described that is particularly suitable for use as a single revolution clutch in a self-processing camera. At the end of one revolution of the clutch, the pawl is uncoupled from the ratchet wheel by a translatable and pivotable clutch release finger. The finger is spring biased towards a first position and includes a ramp at one end thereof that is locatable in the path of the pawl to stop the pawl from further rotation with the ratchet wheel. In the process of stopping the pawl, the finger is translated from the first position and held by the pawl in a second position against the bias of the spring. After the pawl is unseated from its interdental seat on the ratchet wheel the finger is restored by the spring to the first position. An enlarged tooth formed on the ratchet wheel forces the pawl to be moved generally radially outwardly along the ramp so that the pawl is held away from the tips of the smaller teeth of the ratchet wheel.
