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