Major Functional Subsystems of the Joshua Camera
Note:

Erecting, Viewfinder and Camera Optical System

Figure 1-12 shows in simplified form the linkage which erects the Camera and accurately positions the
optical elements for viewing the scene and exposing the picture. When the release button latch on the top of
the strobe tower is depressed, a latch at the base of the strobe unlatches the top cover. Further rotation of
the strobe tower swings the shutter assembly up to a vertical position, where the erecting linkage latches all
pivoted assemblies in place and in proper optical alignment.
The following descriptions and illustrations are
intended to familiarize you with what the Camera
subsystems are. How these subsystems work is
covered in the Theory of Operation section.
