B. Varying the Reproduction Ratio
The reproduction ratio in the drum axial direction (main scanning direction) is varied by the
lens drive system, and that in the drum peripheral direction (sub scanning direction) is changed by
the scanner drive system.
In the lens drive system, the positions of the fixed focal point lens and the No. 4/5 mirror are
changed to vary the reproduction ratio.
In the scanner system, the relative speed of the No. 1 mirror mount is made higher (for reduc-
tion) or lower (for enlargement) than the drum peripheral speed.
