ABSTRACT:
An extensible and retractable compact self-developing camera including a first camera section for exposing and applying pressure to a self-developing film unit and a second camera section coupled in telescoping relation to the first camera section for mutual movement in opposite directions between extended and retracted positions. When extended, the first and second camera sections cooperate to form a film retention and/or imbibition chamber for receiving film units advanced thereinto by a pair of pressure applying rollers. In the retracted configuration, the second camera section slides over a major portion of the first camera section and forms a protective covering over at least the optical elements mounted thereon.
