The Lens is moved by the Lens Drive Cable which is driven by the Lens Motor (stepping
motor). The motor drive pulses sent from the Motor Drive Board drive the Lens Motor to
move the Lens a given distance, corresponding to the zoom ratio, from the reference posi-
tion determined by the Lens Reference Position Sensor.
There is a fixed-type Lens Aperture Cover provided at the rear of the Lens (on the 4th Mir-
ror end). It limits the amount of light striking the surface of the PC Drum.
