ABSTRACT:
An improved photographic apparatus particularly suitable for the exposure and initiation of processing of a self-processing film unit includes a pivotable and translatable shuttle that includes a picker finger for engaging a trailing edge of a film unit and advancing the exposed film unit from its exposure position into the nip between a pair of opposed pressure members. The shuttle includes a rack adjacent one end thereof which is coupled to a gear drive that is also coupled with the pressure rollers. A spring biases the shuttle towards a position wherein the picker finger is disposed to engage the trailing edge of the film unit. After advancement of a film unit from its exposure position a latch or restraint supports the shuttle in an inactive but energized condition against the bias of the spring. The shuttle is releasable from the restraint in response to actuation of the body release. Exposure initiation means in the form of a lever that is pivotally and slidably coupled to the shuttle is associated with the shuttle so that upon release of the shuttle from the restraint the shuttle, under the action of the spring, pivots the lever to actuate a shutter.
An improved photographic apparatus is also disclosed wherein a film transport shuttle includes a hammer supported on a cantilevered spring-like beam. The movement of the shuttle in response to actuation of a body release is used to energize the hammer for striking of a piezoelectric crystal for generation of electrical energy.
