Abstract
A modular photographic system assembly that performs a series of operating functions attendent to the consecutive exposure and processing of a cassette of self-processable film units. The assembly is formed by attaching a group of system function-providing modules to a primary structural member that supports each of the modules in interfacing relationship while simultaneously defining the system exposure chamber. The module group includes a shutter module, gear train module, viewfinder module, and spreader module. Each module is attached to predetermined exterior portions of the primary structural member with snap together type fasteners. Once constructed, the assembly is an independently functioning unit that is adapted for enclosure in a protective chamber formed by mating a camera body and front cover member.
