ABSTRACT:
A camera shutter and focus lens assembly includes a rotary motor having a central shaft, and a rotary beam actuator connected to the shaft. A moveable focus lens, a first shutter blade, and a second shutter blade are in mechanical communication with the actuator beam. Rotation of the shaft by the motor operates to cause movement of the focus lens to effect a selected focusing relationship between the focus lens and a fixed lens proximate thereto, and further operates to cause movement of the first and second shutter blades to cause the shutter blades cooperatively to define an opening to permit light to pass therethrough.
