11-6. Lens Movement
The Lens is moved by the Lens Drive Cable which is driven by Lens Motor M6 (stepping
motor). The motor drive pulses sent from PWB-F drive M5 to move the Lens a given
distance, corresponding to the zoom ratio, from the reference position determined by
Lens Reference Position Sensor PC90.
There is a fixed-type Lens Aperture Cover provided at the rear of the Lens (on the 4th
Mirror end). It limits the amount of light striking the surface of the PC Drum.
