CCD
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. CCD elemental size: 4.7 mm
3. Lens diameter: 18mm dia
4. Light source: LED
5. Effective number of pixel: 7500 pix x 3 color lines, 7500 pix x 1 B/W line
[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.
