7.1 Functions
In this copier, the surface of the original is directly exposed to light, and the reflected light is conducted to
the surface of the drum via the mirror, lens, and slit.
The whole original image is reflected on the drum surface through the light source being scanned from the
leading edge to the trailing edge.
This area where functions as above are performed is called the optical section, located at the upper side of
the copier.
