Installing the Optics Wire

Caution 1: When winding wire around pulleys, be
sure that the winds are close. Be
careful to avoid overlap.
Caution 2: When changing the wire, be sure to
use the optics positioning jigs.
Caution 3: Be sure to perform image adjustment after
installing the CCD unit. (Refer to the
"Adjustment" section.)
a. Procedure (Old Type: With a spring)
(1) Fit the metal ball (midway along each optics wire)
into the mount opening on the drive pulley. Starting
from this position, wind 6 times around the outside
and 5 times around the inside.
• After winding the wires, fasten them in place (with
tape, etc.) so that they cannot come off.
• Use the "F" exposure unit mount fitting (the fitting
with the "F" printed on it) at the front, and use the
"R" fitting at the rear.
• The end with the metal ball at the tip winds around
the inside of the pulley shaft.
• Wind so that the two ends of the wire come off the
top of the pulley.
