6. SCANNER
6.1 Function
In the scanning section of this equipment, the surface of an original is irradiated with a direct light and the
reflected light is led through mirrors, a lens and a slit to CCD where optical-to-electrical conversion is
performed, converting the optical image data into an electrical (analog) signal. This analog signal is changed
to a digital signal, which then undertakes various corrective processes necessary for image formation.
After that, arithmetic operation is performed on the digital signal, which is then transmitted to the data
writing section.
