Flatbed Scanner
Overview
Flatbed Scanner(called Scanner afterwards) plays a role of scanning the original images
and converting them to electric signals. The Scanner consists of Contact glass where the
original is placed, Scan cover Assy, Image reading sensor Assy and Drive Assy supporting
the contact glass, and Scan frame Assy supporting these 3 Assy`s. OP Assy is assembled
and mounted onto the front side of the whole Assy.
The machine size in other words the scannr thickness and the price can be reduced by
using CIS instead of CCD module(using lens) for the Image reading Assy
The CIS optical unit is easy to design for the small units and the price is low, but when
scanning, the images not contacted to the contact glass may not have good images since
the depth of field is dramatically small compared to the reduction optical system.
