CCD Unit

●

Overview

The machine uses the CCD to expose and read an image and the image is read on a line-by-
line basis.
CCD features 4 lines (R, G, B, B/W) and B/W line is used in B/W copy and R, G, B lines are
used at color scan.

CCD overview

1. Integrated scanning configuration; CCD, lens, light source and mirror are integrated.
2. Light source: LED
3. Effective number of pixel: 7500 pix x 3 color lines, 7500 pix x 1 B/W line
4. Color filter: Colored filter (Red/Green/Blue)

[Optical path from LED]
The light generated from LED is reflected by an original and by the 5 mirrors. And then it is
irradiated to the CCD through the lens.
