User's Manual

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 rst 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
identied 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 inuenced by the
setting of the trim wheel. (The trim wheel is the
lighten / darken control on the photocell.)
