F. SHUTTER MECHANICAL DETAILS (Figure 2-9)
The following paragraphs describe the manner in which the mechanical components of the shutter respond to either manual or electrical direction.
1.When the operator prepares to take a picture, he first must aim and focus the camera. As he rotates the focus wheel to bring the split Fresnel
image into focus, a cam molded into the rear surface of the focus wheel moves the component identified as the cam follower assembly. The trim link coupled to the trim assembly is pinned to the cam follower in such a way that follower movement is also directly influenced by the setting of the trim wheel. (The trim wheel is the lighten / darken control on the photocell.)
