Abstract
Abstract Photographic apparatus of the self-developing type including a first housing section having an open end chamber for receiving a film assemblage and a second housing section having a pair of processing rollers mounted thereon. The second housing section is pivotally coupled to the first housing section by a pair of laterally spaced brackets, each of which has an aperture therein for receiving an inwardly facing projection mounted on the first housing section. The second housing section is readily disconnected from the first housing section by pivoting the second housing section to a film loading position and then flexing one of the brackets to a position wherein the projection is withdrawn from the aperture. The second housing section is readily connected to the first housing section by reversing the aforementioned steps.
