Abstract
A photographic apparatus for use with self-developing film wherein the apparatus comprises a light-tight housing assembly having a film unit exit for allowing the film units to exit the housing assembly; an exposure control assembly including a shutter button; the exposure control assembly includes a biased carriage assembly movable between ambient, strobe and strobe charge positions in response to manual displacement thereof; a spread roller assembly including spread rollers for spreading the processing fluid in the film units; a manually operable drive mechanism is mounted in the housing assembly for bidirectional linear movement between extended and retracted positions and carries a pick for engaging and advancing a topmost film unit of the film stack into the nip, and for rotatably driving the spread roller member in response to pulling of the drive mechanism by an operator to process the film unit and eject the same from the exit; and, an interlocking assembly cooperates with the shutter button and the drive mechanism to prevent the drive mechanism from moving until the shutter button is actuated, and preventing the drive mechanism from being reinserted into the housing assembly until the drive mechanism has been pulled sufficiently so that a film unit has been processed by the spread roller member and exits the housing assembly.
