b. Lens Movement and Copying Operation
The microprocessor master and slave (Q115)
retain the positions of the lens in relation to vari-
ous combinations of different original sizes and
copy sizes in memory.
When a change is initiated in the selected
reproduction ratio, it immediately sends drive
pulses for the X motor (M9)/Y motor (M10), there-
by changing the position of the lens (period II in
Figure 3-205).
